Description

  The present invention relates to a cooker for cooking food with steam.

  When cooking food, it is desirable to suppress the cell destruction of the food during cooking and prevent the outflow of nutrients contained in the food so that a nutritious food can be taken. When the food is cooked using an oven (heating cooker), heat can be conducted at an appropriate temperature to the center of the food in a high temperature atmosphere, and nutrients can be prevented from flowing out of the food.

  In recent years, in response to rising health-consciousness, a heating cooker using steam capable of preventing the outflow of nutrients of food and excluding fat components has been proposed (see, for example, Patent Document 1). The heating cooker described in Patent Document 1 includes a heating chamber for heating food and a steam generator for evaporating water supplied by the heater, and a high-temperature steam from the steam generator is transferred to the heating chamber. Supply. The steam supplied to the heating chamber touches the food, and a large amount of heat from the steam conducts to the food. As a result, fat is efficiently removed from the food.

  As shown in FIGS. 3 and 4, the steam generator A has a plate-like water heater 3 having an outlet 31 and a heater 2, and a water supply port 41 to which a water supply pipe 16 is connected. And a horizontally long lid 4 attached to one side of the sheet.

  The water heater 3 is made of a metal material having a high thermal conductivity such as aluminum and an aluminum alloy, and is provided with a plate portion 3a (wall portion) which is long in the lateral direction and substantially rectangular in a front view. A horizontally long first recess 32 is provided at the top of one surface of the plate portion 3a. Further, as shown in FIG. 5, on the other surface of the plate portion 3a, a laterally long second recess 33 and an annular wall 34 projecting from the outer periphery of the second recess 33 are provided.

As shown in FIG. 6, the lid 4 faces the first recess 32, and the lid 4 and the first recess 32 form a horizontally long evaporation chamber 5. On the other hand, as shown in FIG. 5 and FIG.
On the other surface side of a, the laterally long buffer chamber 6 is formed by the other surface of the plate portion 3 a including the second recess 33 and the annular wall 34. The buffer chamber 6 is adjacent to the evaporation chamber 5 via the plate portion 3 a, and the heat of the evaporation chamber 5 is conducted to the buffer chamber 6.

  The heater 2 is embedded in the plate portion 3a along the front-rear direction of the heating chamber 6, and the heater 2 includes a heat source 2a located on the upper side and a heat source 2b located on the lower side. The heat source 2a and the heat source 2b are arranged in the vertical direction. The heat source 2 a is close to the evaporation chamber 5, and the heat source 2 b is separated downward from the evaporation chamber 5. The heat source 2 a and the heat source 2 b are close to the buffer chamber 6. That is, the heat source 2a is mainly used to evaporate water, and the heat source 2b is mainly used to heat steam.

  The heat source 2 b is located near the outlet 26. Therefore, the temperature of the steam rises in the vicinity of the outlet 26, and the steam heated to a high temperature is immediately supplied to the heating chamber 11. Further, by arranging at a position away from the evaporation chamber 5, the heat of the heat source 2b is mainly conducted to the buffer chamber 6, and the temperature of the buffer chamber 6 rises rapidly.

  The heater 2 is disposed between the buffer chamber 6 and the evaporation chamber 5 so that the heat of the heater 2 is supplied to both the chambers to improve the thermal efficiency for evaporation and reheating of the vapor. Further, the heat source 2a and the heat source 2b are positioned in a plane substantially parallel to the plate portion 3a, and the thinning and downsizing of the steam generating container A are promoted, and the steam in the narrow space between the housing 1 and the heating chamber 11 It becomes easy to arrange generation container A.

  An outlet 31 is opened at the top of the plate portion 3a. When water is supplied from the water supply port 41 to the evaporation chamber 5, the water is evaporated in the evaporation chamber 5 by the heat source 2a, and the generated vapor is drawn out to the buffer chamber 6 through the outlet 31 and stored.

  The outlet 31 is located above the outlet 26. The vapor supplied from the outlet 31 fills the inside of the buffer chamber 6 and is blown out from the blowout port 26 located on the lower side. Therefore, a large amount of steam is heated in the buffer chamber 6 and the high temperature steam is supplied to the heating chamber 11 without interruption.

  In the plate portion 3a, an extending portion 3b extending in a tapered shape upward from one lateral side of the plate portion 3a and facing the water supply port 41 is integrally provided. The first recess 32 is formed across the extension 3b. The first recess 32 is recessed in the direction away from the lid 4.

  The U-shaped heater 2 is embedded in the lower portion of the plate portion 3a by die casting with the heat source 2a on the upper side and the heat source 2b on the lower side. The curved portion of the heater 2 is located below the extension 3b. At the upper part of the plate portion 3a, two mounting pieces 35, 35 protruding upward are provided integrally in a laterally separated manner. The mounting piece 35 is provided with a fitting hole 35a into which the mounting shaft 27 is fitted.

  As shown in FIGS. 5 and 6, in the water heater 3, a temperature sensor 7 is provided at a position below the extension 3b and facing the curved portion of the U-shaped heater 2. As shown in FIG. The temperature sensor 7 includes an element (thermistor) whose electric resistance value changes in accordance with a temperature change, and monitors the temperature of the water heater 3 to be exhausted in the evaporation chamber 5 or the temperature in the evaporation chamber 5 It is used to prevent shortage. Further, an annular groove 3c is provided in the peripheral portion of one surface of the plate portion 3a, the sealing member 36 is fitted and held in the annular groove 3c, and a gap between the sealing member 36 and the lid 4 is sealed.

  The first recess 32 has a deep bottom 32a which is recessed over the extension 3b, and a shallow bottom 32b connected to the lower edge of the deep bottom 32a via a curved corner. A heat source 2a for evaporation is disposed at a position facing the lower surface of the deep bottom portion 32a and the shallow bottom portion 32b.

  The lid 4 is provided with a plate portion 4a which is long in the lateral direction and has a substantially rectangular shape in a front view. At the lower part of the plate portion 4a, an outward convex portion 4b protruding in a direction away from the water heater 3 is provided. The inner surface of the outward convex portion 4 b is a horizontally long third recess 42. The first recess 32 and the third recess 42 form a laterally long evaporation chamber 5 along the heat source 2a for evaporation.

  As shown in FIGS. 4 and 6, one side along the lateral direction of the plate portion 4a has an extending portion 4c which is extended upward in a tapered manner. In the central portion excluding the peripheral edge of the extending portion 4c, an inward convex portion 43 whose outer surface is a circular recess and whose front end faces one surface of the extending portion 3b is formed. The water supply port 41 is opened at the center of the inward convex portion 43, and the tip end of the water supply pipe 16 is fitted and held in the water supply port 41. The peripheral portion of the lid 4 is removably attached to the peripheral portion of the water heater 3 by a plurality of male screws.

  The tip end of the water supply pipe 16 extends from the water supply port 41 toward the extending portion 3 b, and is opposed to one surface of the extending portion 3 b at a slight interval. Therefore, the water supplied from the water supply pipe 16 to the evaporation chamber 5 flows down along one surface of the extending portion 3b.

  The lower surface of the third recess 42, in other words, the lower surface of the evaporation chamber 5 is inclined so that the outlet 31 side is high and the water supply port 41 side is low, and the supplied water flows down to the lower surface of the evaporation chamber 5 , Can be evaporated on the side away from the outlet 31.

  The outlet 31 penetrates the upper portion of the plate portion 3a and has a long oval shape in the lateral direction. Further, the outlet 31 is a position separated from the water supply port 41 in the lateral direction, and is disposed at substantially the same position as the water supply port 41 in the vertical direction.

  As described above, the vapor generated in the evaporation chamber 5 flows through the outlet 31 and is discharged to the buffer chamber 6. As shown in FIGS. 5 and 7, the buffer chamber 6 is formed by the other surface of the plate portion 3 a including the second recess 33 and the annular wall 34. A plate-like guiding wall which is long in the lateral direction at the central portion of the buffer chamber 6 and which guides steam in a direction intersecting the thickness direction of the plate portion 3a from the outlet 31 (direction along the other surface of the plate portion 3a) 37 are provided. The guide wall 37 protrudes toward the heating chamber 11 from the other surface of the plate portion 3a. The vapor of the buffer chamber 6 meanders along the guiding wall 37 and flows for a long time, and a large amount of heat is supplied to the vapor from the heating chamber 11. Also, if the guiding wall 37 is designed to be long, the amount of heat supplied to the steam will increase.

  The induction wall 37 is located between the heat sources 2a and 2b in the vertical direction. The heat source 2 a is located between the upper surface of the guiding wall 37 and the annular wall 34, and the heat source 2 b is located between the lower surface of the guiding wall 37 and the annular wall 34. The heat sources 2a and 2b extend laterally along the guiding wall 37. Therefore, while moving in the steam passage formed by the induction wall 37 and the annular wall 34, heat is continuously supplied to the steam of the buffer chamber 6 from the heat sources 2a and 2b.

  As shown in FIG. 5, the end of the guiding wall 37 on the side of the outlet 31 is bent downward and is in contact with the inner surface of the lower wall of the annular wall 34. A water reservoir 3 d is formed between the downwardly bent portion of the guiding wall 37 and the annular wall 34. At the end of the guide wall 37 opposite to the outlet 31, a convex portion 37a protruding upward is provided. Water accumulated on the upper surface of the guiding wall 37 becomes difficult to move over the convex portion 37a and easily flow down to the reservoir 3d.

A second temperature sensor 8 is provided in the reservoir portion 3d. The temperature sensor 8 includes an element (thermistor) whose electric resistance value changes in accordance with a temperature change, and monitors the water level in the reservoir 3 d based on the temperature change. When a predetermined amount of water is stored in the reservoir portion 3d, the temperature sensor 8 is turned on to detect water overflow into the buffer chamber 6. When the temperature sensor 8 is turned on, the control unit controls the drive of the heater 2 to heat the heater 2, for example.

  The longitudinal cross-sectional area (the area of the cross section orthogonal to the flow direction of the steam) between the induction wall 37 and the annular wall 34 is larger than the opening area of the outlet 31. For this reason, the pressure of the steam drawn out from the outlet 31 into the buffer chamber 6 is reduced, and bumping is less likely to occur in the reservoir portion 3 d.

  In the buffer chamber 6, the lower side of the guiding wall 37 faces the air outlet 26. The vapor discharged from the outlet 31 in the thickness direction of the plate portion 3a moves in the left direction in FIG. 3 above the guiding wall 37 and wraps around the convex portion 37a to turn the lower side of the guiding wall 37 to the right It moves and is blown out from the blowout port 26 to the heating chamber 11.

  The longitudinal cross-sectional area between the induction wall 37 and the annular wall 34 is wider than the total opening area of the plurality of outlets 26, and the flow velocity of the steam rises near the outlets 26. Therefore, the steam flows smoothly in the buffer chamber 6 and the pressure rise in the buffer chamber 6 is suppressed.

  Further, compared with the case where the outlet 31 and the outlet 26 face in the blowing direction, the flow path of the steam from the outlet 31 to the outlet 26 becomes longer, and while the steam flows in the buffer chamber 6 The heat of the heating chamber 11 heats the steam. Further, the steam is prevented from moving linearly from the outlet 31 to the outlet 26.

  As shown in FIG. 7, on the other side of the plate portion 3 a below the guide wall 37, a horizontally elongated groove-shaped recess 3 e is formed deeper than the second recess 33. Therefore, the volume of the buffer chamber 6 is increased, a larger amount of vapor is stored in the buffer chamber 6, and the heating efficiency is improved.

  Between the left and right of the guiding wall 37 in the buffer chamber 6, and between the guiding wall 37 and the lower wall of the annular wall 34, a cylindrical heat radiating portion 3f projecting from the other surface of the plate 3a is integrated with the plate 3a. It is provided. By providing the heat radiating portion 3 f, the contact area of the steam in the water heater 3 is increased.

  As shown in FIGS. 3 and 7, an annular sealing member 38 in contact with the right side surface 11 a of the heating chamber 11 is fitted and held at the tip of the annular wall 34. The sealing member 38 protrudes to the inside of the annular wall 34 and is provided with a frame-like close contact portion 38 a along the annular wall 34. The thickness dimension at the proximal end of the adhesion portion 38a is shorter than the thickness dimension at the projecting end portion of the adhesion portion 38a. Therefore, the contact portion 38 a is easily bent with the base end as a fulcrum and is pressed against the heating chamber 11 by the vapor pressure.

  Further, a sealing member 39 in contact with the right side surface portion 11a is fitted and held at the tip of the guide wall 37. The sealing member 39 prevents the steam from flowing between the guide wall 37 and the right side surface 11a, and prevents the steam from moving linearly from the outlet 31 to the outlet 26, thereby heating The heat of the chamber 11 is sufficiently conducted to the vapor stored in the buffer chamber 6.

  When the steam generator A is attached to the right side 11a of the heating chamber 11, as shown in FIGS. 4 and 7, the attachment shafts 27, 27 are inserted into the insertion holes 35a, 35a of the steam generator A, and the attachment shaft 27 The nuts 28, 28 are screwed into the tip of the 27. The steam generator A is easily positioned by the mounting shafts 27, 27 and mounted on the right side surface portion 11a so that the position with respect to the blowout port 26 is appropriate. Further, the sealing members 38 and 39 are in contact with the right side surface portion 11a, and the buffer chamber 6 is closed by the right side surface portion 11a, resulting in a closed chamber state. Further, the heat in the heating chamber 11 is conducted into the buffer chamber 6 through the right side surface portion 11a. That is, the vapor in the buffer chamber 6 is reheated by the heat in the heating chamber 11. The buffer chamber 6 is sandwiched between the heating chamber 11 and the evaporation chamber 5, and the temperature in the buffer chamber 6 is maintained at a high temperature.

  The outlets 26 are arranged in two upper and lower rows corresponding to the upper and lower trays 60, 60. However, when three or more trays 60 are accommodated in the heating chamber 11, they are made to correspond to the tray 60. The outlets 26 are also arranged in three or more rows.

  In the heating cooker according to the first embodiment, the buffer chamber 6 is adjacent to the heating chamber 11, and the heat of the heating chamber 11 is conducted to the buffer chamber 6. Therefore, the vapor generated in the evaporation chamber 5 is reheated in the buffer chamber 6, and the vapor can be safely heated without excessively raising the temperature of the heater 2, and the vapor is reheated. Power consumption can be reduced. Further, since the steam is blown out to the heating chamber 11 via the buffer chamber 6, the pressure of the steam can be appropriately adjusted by changing the design of the buffer chamber 6.

  Further, the buffer chamber 6 is adjacent to the evaporation chamber 5, and the heat of the evaporation chamber 5 is conducted to the buffer chamber 6. Therefore, the heat for generating steam is used for steam reheating, and energy efficiency is improved.

  Further, since the buffer chamber 6 is located between the evaporation chamber 5 and the heating chamber 11, the heat of the evaporation chamber 5 and the heating chamber 11 is conducted to the buffer chamber. Therefore, the heat of both chambers is utilized for reheating of steam, and the energy efficiency regarding the reheating of steam can be dramatically improved. Further, the temperature in the buffer chamber 6 can be maintained at a high temperature by being sandwiched between the two chambers.

  Further, the heater 2 is disposed between the buffer chamber 6 and the evaporation chamber 5, and the heat of the heater 2 is supplied to both the chambers, whereby the thermal efficiency for evaporation and reheating of the vapor can be improved. In addition, downsizing of the steam generation container A can be promoted.

  In the heating cooker according to the first embodiment, the right side surface portion 11a of the heating chamber 11 doubles as the wall portion of the buffer chamber 6, but the opposing wall portion of the buffer chamber 6 facing and contacting the right side surface portion 11a You may provide. In this case, the heat of the heating chamber 11 conducts through the right side surface portion 11 a and the opposite wall portion, and the vapor in the buffer chamber 6 is heated.

  The guiding wall 37 extends in the lateral direction in the buffer chamber 6 but may extend in the vertical direction from the top or bottom surface of the buffer chamber 6.
