Description

  The present invention provides a cooking space that is separated from the outside by a bottom surface, a wall portion, and a front door, a steam generator, a first heating device disposed in at least one of the wall portions, and a bottom surface. It is related with a composite steamer provided with the arranged 2nd heating device.

This type of known combined-type steamer (Patent Document 1) enables cooking with hot air and / or steam. A combined steamer is generally a combination of a steam cooker and an oven. Inside, it is either baked with natural heat or cooked with steam. Also, the food to be cooked can be simply steamed, and in this case, for example, water at 100 ° C. is repeatedly sprayed. In the conventional combined steamer, such sprayed water is evaporated by the first heating device. The first heating device is attached to the wall surface in the cooking space, and surrounds a blower that circulates steam generated during cooking in the cooking space.
In general, in a combined steamer, it is not easy to directly heat a cooked product, and therefore it is not possible to cook a specific cooked product such as pizza, flammkuchen, and Gemuskuchen satisfactorily. Therefore, the conventional combined-type steamer has equipment capable of sufficiently cooking even a pizza or the like. For this reason, the conventional composite steamer has a refractory stone that can be inserted into a cooking space. The refractory stone can be heated by the second heating device arranged in the cooking space. In addition, the conventional composite steamer includes an air induction plate in the cooking space, and the air induction plate isolates the ventilator chamber in which the first heating device and the blower are arranged.
Thus, in the cooking space of the conventional combined steamer, there are many obstacles that restrict or interfere with the equipment of the cooking space and make it difficult to clean. In addition, the second heating device used to heat the refractory stone in the conventional composite steamer is not suitable for solving the problem that the food to be cooked cannot be burned with the composite steamer. The reason is that when using a combined steamer in the field of food and beverage industry, the food to be cooked is heated in a dry state, so that the food is heated with a frying pan. In this case, the food is heated to a relatively high temperature of, for example, 200 to 250 ° C. Since a large amount of steam is generated in the water filling process, the steam must be exhausted and discharged to the outside. Or you have to open the door of the combined steamer and take it out before sucking it out. For this purpose, a combination of a fume discharge hood and a combined steamer already exists (see Patent Document 2). It would be advantageous if meat could be baked inside the combined steamer itself and cooking could be completed with steam, but such a combined steamer has so far been known to the applicant. not exist.

On the other hand, another known oven (Patent Document 3) includes a heating device disposed in the oven chamber. This heating device is also an obstacle in the oven chamber, and is provided only for the purpose of heating the brick with radiant heat. That is, the conventional oven is intended to solve the problem of baking even pizza or the like, similar to the above-described conventional composite steamer.
German Utility Model Application Publication No. 201058820U1 Specification International Publication No. 2006/042307 Pamphlet German Patent Application Effect No. 3602398A1 Specification

  An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and further expand the range of use of the composite steamer.

Means for Solving the Problems and Effects of the Invention

  Such a problem is that according to the present invention, in the combined steamer of the type described at the beginning, both heating devices are arranged outside the cooking space, and the cooking area is provided with the second heating device on the bottom surface. It can be solved by configuring as.

In the combined steamer according to the present invention, since both the heating devices are arranged outside the cooking space, there is no obstacle inside the cooking space. By configuring the bottom surface as a cooking area, it is possible to place a frying pan containing food to be baked in the cooking area. Also, after cooking, switch off the cooking area and operate the combined steamer as a low-temperature cooker to slowly cook the baked food, or operate as a high-temperature cooker to complete cooking quickly You can also In order to complete the cooking, instead of placing the frying pan with baked food on the cooking space insert plate at a distance above the cooking area and switching off the cooking area, It can also be used for heating.
The frying pan may be a GN (for food and beverage industry) container made of a multilayer material placed on the insertion shelf above the bottom surface. In addition, the steam generator can be switched on to facilitate cooking completion with steam. The composite steamer according to the present invention does not require a blower in the cooking space, unlike the known composite steamer described at the beginning. This is because the heat rising from the cooking area where the switch is turned on generates sufficient convection inside the cooking space. That is, there is no obstacle in the form of a blower in the cooking space of the composite steamer according to the present invention. However, it does not exclude a configuration in which a blower is provided outside the cooking space and the discharge section is connected to the cooking space. This also applies to the steam generator, and the steam generator can be arranged outside the cooking space in the same manner as the blower and connected to the cooking space on the steam outlet side.

  The main advantage of the combined steamer according to the present invention is that it can be used not only as a combined steamer and / or oven, but also as a range or grill plate. This is because the bottom of the cooking space of the combined steamer can be used for cooking food as well as the cooking area of the range. Therefore, the convenience of the composite steamer according to the present invention is greatly expanded compared to the prior art.

  Preferred embodiments of the invention are the subject of the dependent claims.

  In one embodiment of the combined steamer according to the present invention, if the cooking area can be pulled out from the cooking space, it is possible to improve the convenience of the range and use it more comfortably. In particular, by opening the door and pulling out the cooking area, the combined steamer can be quickly changed to a complete range. In addition, this eliminates the need for a separate oven, separate steam cooker, and separate cooking area in the kitchen, eliminating the need for a single line and simplification of the arrangement, which is extremely beneficial for single-person households, for example. .

  In another embodiment of the composite steamer according to the present invention, when the cooking area is a cooking area made of Ceran (registered trademark) or the like, the bottom surface of the cooking space of the composite steamer is easily realized using a commercially available cooking area. it can.

  In another embodiment of the composite steamer according to the present invention, when the cooking area has a plate made of a metal multilayer material, an additional advantage is obtained as compared with the configuration of the cooking area as a cooking area made of Ceran or the like. Known multi-purpose work plate-like structure for range or grill (German Utility Model Registration Publication No. 202159779U1) or known induction-type grill plate structure (German Patent Application Publication No. 10120500B4) Since the metal multilayer plate having can be heated by itself, it can be used as a heat source for the cooking space. Also, its own temperature does not increase when the second heating device is activated, but is different from a Ceran cooking area where heat released from the radiant heating device can enter the cooking space. The metal multilayer material of the plate forming the cooking area can be heated as such by means of a radiant heat source or an induction heating device, so that it functions as a heat source. Furthermore, a plate made of a metal multilayer material can itself be used as a grill plate.

In another embodiment of the composite steamer according to the present invention, when the second heating device is a radiant heating device and / or an electromagnetic induction heating device, depending on the desired use purpose of the cooking area forming the bottom surface of the cooking space Thus, an appropriate configuration of the second heating device can be selected. For example, when an electromagnetic induction heating device is provided in an area made of Ceran, only an electromagnetic induction cooking utensil placed on the cooking area can be heated. In addition, when it is desired to use the Ceran surface as a heat source for the cooking space, the second heating device is configured as a radiation and induction heating device.
On the other hand, when the cooking area | region which forms the bottom face of a cooking space has the plate which consists of a metal multilayer material, a 2nd heating apparatus can be made into a radiant heating apparatus or an electromagnetic induction heating apparatus. In addition, the second heating device can be configured as a radiation and induction heating device.

  In another embodiment of the composite steamer according to the present invention, the cooking area has a plurality of cooking surfaces, and the second heating device includes a plurality of heaters individually attached to these cooking surfaces. The cooking area that forms the bottom surface of the cooking space provides an environment in which a plurality of cooking utensils can be used simultaneously when cooking food by using the cooking area like a range. An advantageous modification of this embodiment includes the configuration of the cooking area as a cooking area that can be pulled out like a drawer from the cooking space. When the cooking area has a plate made of Ceran, or has a plate made of metal multilayer material, a metal multilayer material cooker also having electromagnetic induction capability can be advantageously used. Multilayer containers suitable for such applications are known (WO 2006/072459 pamphlet). If this container is configured as a GN container, it is more advantageous to use a known container made of a metal multilayer material. Furthermore, another advantage of the combined steamer according to this embodiment, where the cooking area has multiple cooking surfaces, is that multiple foods can be baked in the cooking space simultaneously, or generally heated for preparation. It can then be mentioned that these foods can be cooked together in a combined steamer which in this case operates as an oven and / or steam cooker.

  In another embodiment of the composite steamer according to the present invention, when the outlet for waste steam and waste air is provided in the cooking space, the above-described fumes exhaust hood according to Patent Document 2 can be combined with the composite steamer according to the present invention. It is possible and suitable. In that case, the composite steamer of the present invention provided with such a fume discharge hood is particularly preferable because it can be used as a range by pulling out the cooking area from the cooking space like a drawer. This is because steam generated when cooking food can be sucked into the fume hood through the waste steam and waste outlet, cleaned there, and then released again around the combined steamer. . The composite steamer configured as such a ventilator can be installed in the center of the room. That is, as still another preferred embodiment of the composite steamer according to the present invention, a fume exhaust hood connected to the outlet of waste steam and waste air can be provided above the composite steamer.

  When the fume hood is not connected to the outlet, the waste steam and waste gas outlet of the cooking space can be communicated outdoors. However, this configuration is inferior to the ventilated solution in terms of energy. This is because in the latter case, the air is only cleaned and does not need to be heated again.

  Furthermore, in another embodiment of the composite steamer according to the present invention, when at least one of the walls is configured as a heating region provided with the first heating device, the convection generated by the cooking region on the bottom surface is strengthened. The cooking space can be brought to the proper temperature more easily and quickly. Therefore, it is preferable that at least one or two side walls are each configured as a heating region provided with the first heating device. Alternatively, or in addition to this, the upper wall of the cooking space can also be configured as a heating region including the first heating device. This has the further advantage that this heating area can also be used as a grill and thus an additional grill bar can be omitted. Additional grill bars that are normally available in the oven must be plugged into corresponding receptacles on the back wall of the oven, but such additional grill bars can be omitted. This means that although there is a possibility of grilling even in the combined steamer according to the present invention, it is not necessary to install any obstacles such as an additional insertion grill bar and its insertion port in the cooking space due to the presence of the grill. It is associated with another advantage. As described above, in the combined steamer of the present invention, the cooking space has an entirely smooth inner surface on any side, so that the advantages obtained with the conventional combined steamer can be enjoyed in addition to this. It also offers the possibility that the cooking area at the bottom can be used as a cooking area or a range plate.

  In another embodiment of the composite steamer according to the present invention, if the heating region has a plate made of Ceran or the like or a plate made of a metal multilayer material, as described above in connection with the second heating device, The optimum first heating device attached to the heating region can be selected according to the purpose of use.

  In another embodiment of the combined steamer according to the present invention, if the first heating device is a radiant heating device and / or an electromagnetic induction heating device, as described in relation to the second heating device, the heating device You can choose the most suitable one.

  In another embodiment of the composite steamer according to the present invention, the blower is arranged outside the cooking space and connected to the cooking space on the suction side and the discharge side through an opening in one of the walls. Can be provided. With this blower, air circulation and / or steam circulation in the cooking space caused by convection can be enhanced as necessary. The blower is merely connected to the cooking space on the suction side and the discharge side through an opening provided in one of the walls. That is, since it is arranged outside the cooking space as a whole, there is no obstacle or interference in the cooking space by the blower. Especially in the cooking space, unlike the prior art described in Patent Document 1 mentioned at the beginning, it is not necessary to separate the ventilator chamber from other cooking spaces by the air guide plate. Therefore, even when the blower is used in the embodiment of the present invention described above, the inside of the cooking space is maintained without any obstacles.

  This also applies to a configuration in which the steam generator is arranged outside the cooking space and connected to the cooking space on the steam outlet side as another embodiment of the combined steamer according to the present invention. This is because the cooking space is maintained without any obstacles in this case.

  In another embodiment of the composite steamer according to the present invention, when at least one ferromagnetic layer that can be used for controlling the Curie temperature is roller-coated inside or on the surface of the metal multilayer material, Above the temperature, there is an advantage that the phenomenon that the thermal energy destroys the ferromagnetism and the ferromagnetic material exhibits a paramagnetic behavior can be used. This is realized in the form that the ferromagnetic material loses its magnetism above this temperature, so that the multilayer material is not overheated. This allows temperature control in the cooking chamber through the multilayer material. Furthermore, this makes it possible to utilize a plate made of a multilayer material by providing a recess capable of filling water as a steam generator.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a first embodiment of a composite steamer according to the present invention, generally designated by reference numeral 10. In the first embodiment and each embodiment described below, the composite steamer 10 is a so-called composite steamer, that is, a combination of a steam cooker and an oven. The combined steamer 10 is separated from the outside by a bottom surface 14, two side walls 15 and 16 (the latter is shown only in FIG. 4), a rear wall 18, an upper wall 20, and a front door 22. The cooking space 12 is configured. Note that the steam generator 24 and the selectively added blower 26 are shown only in FIG. 4, so these are described in detail in the description of the third embodiment related to the composite steamer 10 ″ shown in FIG. 4. Describe.
In a composite steamer, the bottom surface 14 is usually a continuous bottom surface. For example, in the prior art described at the beginning, a second heating device is arranged inside the cooking space for baking pizza. However, in the composite steamer 10 described here, unlike such a conventional technique, the bottom surface 14 is configured as a cooking region 32 provided with a second heating device denoted by reference numeral 30 here. Strictly speaking, in the first embodiment of the composite steamer 10 according to the present invention described here, the cooking region 32 is inserted into the bottom surface 14, thereby substantially forming the bottom surface and cooking. It fulfills the bottom function of dividing the space 12 at the bottom. Furthermore, on the cooking area 32, the food put in the cooking utensil (not shown) can be cooked by the same method as the conventional range. That is, for example, meat can be grilled. This is impossible to achieve with steam in a steam cooker.
Since the second heating device 30 is disposed below the cooking area 32, it is located outside the cooking space 12. The second heating device 30, which is only indicated by a reference numeral in FIG. 1, can be a radiant heating element such as a heating coil or an induction heating device such as an electromagnetic induction coil. On the other hand, when the cooking region 32 is a cooking region made of Ceran or the like, the second heating device 30 is configured as a radiant heating device and / or an induction heating device. The bottom wall of the composite steamer 10 is shown as a heat-insulating wall in FIG. 1, and the cooking area 32 is inserted together with the second heating device 30. Other wall portions are similarly heat insulating.

In the composite steamer 10 according to the first embodiment, both side walls 15 and 16 facing each other (the side wall 16 is not shown in FIG. 1 and shown in FIG. 4 as described above), and the rear wall 18 are also Each of the heating regions 31 including the first heating device 28 has the same structure as the bottom surface 14. There is no fourth side wall, and an access opening to the cooking space 12 that can be closed by the door 22 is formed. Thus, unlike the prior art described at the beginning, the side walls 15, 16 and the rear wall 18 are also continuous wall portions, and the first heating device is located behind these walls, that is, outside the cooking space 12. Each is arranged. Each heating region 31 has a plate made of Ceran or the like or a plate made of a metal multilayer material. Each of these plates is inserted into the wall portion to play the role of a wall portion that separates the cooking space on the side. In addition, it is possible to heat the cooking space while eliminating the need to place any of the first heating devices inside the cooking space.
The metal multilayer material which comprises the plate of the cooking area | region 32 or the plate of each heating area | region 31 can utilize the thing similar to the prior art mentioned above. Such multi-layered materials typically have a thick intermediate layer formed of a material with good thermal conductivity, such as aluminum, for example, with two coating layers formed of much thinner stainless steel. Configured. One of both coating layers can be made of ferritic steel. That is, a material that can be magnetized well can be used. The other coating layer can be formed of an austenitic steel material. That is, it is possible to use a material that can be slightly magnetized. Alternatively, one coating layer or both coating layers may be made of a ferromagnetic steel material.

  The cooking area 32 has a plurality of cooking surfaces (indicated by reference numerals 32a and 32b in FIG. 4). In this case, the second heating device 30 includes a plurality of heaters (indicated by reference numerals 30a and 30b in FIG. 4), one of which is added to one of the cooking surfaces. Here, the composite steamer can be used as a range when the door 22 is opened (in this case, the switch of the heating region 31 is turned off). The door 22 is then closed and the combined steamer 10 can be operated as an oven and / or steam combined steamer (in this case the heating zone 31 and the steam generator 24 (not shown in FIG. 1) are switched on). To do).

  In the combined steamer 10 shown in FIG. 1, the heat generated and rising in the cooking area 32 and the heating area 31 generates sufficient convection inside the cooking space 12. Thereby, the air blower 26 required for the cooking space of the conventional composite steamer can be omitted.

  FIG. 2 shows a composite steamer according to a second embodiment of the present invention, which is denoted by reference numeral 10 '. In this combined steamer 10 ′, a heating area 31 is additionally inserted into the upper wall 20 of the cooking space as compared with the first embodiment. The heating area 31 on the upper wall 20 has the same structure as the heating area 31 of the walls 15, 16 and 18, or has the same structure as the cooking area 32 of the bottom surface 14. Therefore, this combined steamer 10 'can additionally utilize the heating of the upper part in the cooking space 12, thereby eliminating the need for the plug-in grill normally provided in the prior art. Furthermore, the heating area 31 of the top wall 20 can improve uniform heating in the cooking space. This is particularly advantageous when the combined steamer operates as an oven. The cooking area 32 can be constituted by an electromagnetic induction grill plate made of a multi-layer plate capable of electromagnetic induction in both the composite steamer 10 shown in FIG. 1 and the composite steamer 10 ′ shown in FIG. 2. Such a multilayer plate can utilize the structure described above for the multilayer material. The electromagnetic induction grill plate can use the configuration disclosed in the above-mentioned German Patent Application Publication No. 10120500B4 from any viewpoint.

  FIG. 3 shows a composite steamer generally denoted by reference numeral 10 ″ as a third embodiment of the present invention. In the combined steamer 10 ″, as shown in FIG. 3, the cooking area 32 is configured as a cooking area that can be slid out of the cooking space 12. FIG. 4 shows the front surface of the combined steamer 10 ″, and the door 22 of the cooking space 12 is not shown for easy viewing of the drawing. In the case of the combined steamer 10 ″, the cooking area 32 forms the bottom surface, that is, forms the lower partition of the cooking space 12. The drawable configuration of the cooking area 32 to the position shown in FIG. 3 facilitates the work of the user of the combined steamer 10 ″ when using the cooking area 32 as a range. Similar to the two embodiments described above, the cooking area 32 can have a plurality of cooking surfaces, and the two heating devices 30 can have a plurality of heaters individually added to the cooking surface. In the embodiment shown in FIGS. 3 and 4, the second heating device 30 includes two heaters 30a and 30b. The bottom surface 14 has a concave portion opened toward the door 22 toward the front, and when the cooking area is not used as a range outside the cooking space 12, the cooking area 32 can be inserted and stored in the concave area.

In the combined steamer 10 ″ shown in FIGS. 3 and 4, the cooking space has outlets for waste steam and waste air. Further, a haze exhaust hood connected to the outlet 40 and generally designated by reference numeral 42 is disposed above the combined steamer. The smoke discharge hood 42 can have a structure similar to the structure disclosed in Patent Document 2 described above. The details of the smoke exhaust hood having such a structure will not be specifically described here, but a suction opening 44 (shown in FIG. 3) above the door 22, a suction filter structure, a unique suction fan, A condensing heat exchanger for dehydrating steam drawn from the cooking space 12 through the outlet 40 or taken in through the opening 44, a connection to the outlet 40, and preferably a fume exhaust hood 42 It includes an outlet opening 46 (shown as an outlet connecting pipe in FIGS. 3 and 4) that leads to the nearest point. The exhaust passage communicates with a bypass passage that leads to the upstream side of the suction filter structure, and an air flow generated by a suction fan is supplied to the condensation heat exchanger. Such a structure ensures that the air exiting the fume hood through the outlet opening 46 is free of particles including oil droplets. The bypass passage leading to the upstream side of the suction filter structure first removes particles (including oil droplets) from the exhaust from the combined steamer 10 ″ via the outlet 40 to the fume discharge hood 42 and then concentrates it. It is ensured that the heat exchanger is reached and discharged from the fume discharge hood 42 via the outlet opening 46. Therefore, the inside of the smoke discharge hood 42 is not soiled with oil and fat, and the surroundings are not contaminated with undesirable particles.
A plasma module can also be arranged in the suction passage downstream of the suction filter structure. By such an exhaust treatment of the plasma module, particularly gaseous organic carbon compounds such as odor molecules can be removed so as to suit the environment. This technology also serves to disinfect the air. This type of air purification is disclosed as a publication in, for example, German Patent Application Publication No. 10312309A1 and European Patent Application Publication No. 1249265B1. When the cooking area 32 is pulled out and operated as a range, the cooking space 12 sucks out steam generated when cooking the food and discharges it again into the space around the combined steamer 10 ″ as cleaned circulating air. To do so, it can be used with a fume hood 42 communicated to the cooking space. At this time, steam generated when the food is cooked is additionally taken into the fume discharge hood 42 through the suction opening 44.

  In the first and second embodiments of the combined steamer, if it is desired to further enhance the convection generated in the cooking space, a blower 26 can be further added behind the side wall 16. A steam generator 24 is also provided behind the side wall. The blower 26 communicates with the cooking space 12 on the suction side and the discharge side through the openings 27 to 27a of the side wall 16. Similarly, the steam generator 24 disposed outside the cooking space 12 communicates with the cooking space on the steam outlet side.

  Furthermore, at least one ferromagnetic layer that can be used for temperature control of the Curie temperature can be roller-coated inside or on the surface of the metal multilayer material in the cooking region 32 or each heating region 31. The Curie temperature is 260 ° C., for example. The Curie temperature is the upper limit temperature at which the ferromagnet exhibits ferromagnetism, and when this temperature is exceeded, it means that the metal multilayer material loses its magnetism and exhibits inductivity. For example, in order to prevent overheating of the cooking region 32 or the heating region 31, the above characteristics can be used for temperature control. One suitable ferromagnetic material is a soft magnetic iron-nickel-chromium alloy named PHYTHERM 260 from Imphys Alloys, which belongs to the Arcelor group, which was developed for an electromagnetic induction cooker. is there.

  The steam generator 24 shown and arranged behind the side wall 16 in the embodiment of FIG. 4 is connected to a water supply in the case of a cooking area 32 having a plate made of metal multilayer material, or as required. It is also possible to replace it with a depression (not shown) provided in the plate, which can be manually filled with water.

  The wall portions 15, 16, 18, and 20 of the cooking space 12 are provided with insertion shelves as in the conventional oven. The insertion shelf can be arranged at the height at which the insertion plate is selected. The food to be cooked is placed on the insertion plate as it is or in a cooking container. Such an insertion shelf is not shown. For the cooking area to be drawn out of the cooking space 12, FIGS. 3 and 4 show grooves 48 to 50 which are guides for guiding the peripheral edge outside the cooking area 32.
