Description

food cooker

technical field

The utility model belongs to the technical field of cooking appliances, and relates to a food cooking appliance with a base and a cooking container.

Background technique

For a long time, people have relied on heating to make food ingredients more fragrant, delicious and nutritious. Obviously, in the early food cooking, the juice of the food would be stained on the firewood or the grill, and later people used pots, pots and other containers to hold the food when heating.

The invention of the pot thousands of years ago marked a major advance in the preparation of food by humans. It simplifies the steps of food preparation. The pot can cook scattered food together and better control the time and temperature. So there are recipes that allow people to make delicious food.

These basic concepts of holding food in containers for heating were later applied to the design of countless pots and pots, including pressure cookers, steamers, double-burner electric stoves, and other complex control devices.

Significant advances in the cooking process also include simplification in the provision of heat. From firewood at the beginning to natural gas later, from hydrocarbons to electricity to generate heat. Recently, most products are still directly heated by electricity, that is, conductive devices such as nickel-chromium heat-resistant wires or blocks are surrounded on the cooking container to increase its temperature, and the heat energy is conducted from bottom to top to the cooking container for heating. cooking food. This heating method is to heat from the outside of the cooking container, and the heat energy is transferred from the outside to the inside, which tends to cause uneven heating of the food, overheating or even burning the food on the outer layer, while the food in the middle is still in an unheated or undercooked state.

In addition, in most cases, the electronic control is connected to the heating device outside the cooking vessel, the most common "ceramic liner" is a ceramic bowl connected to a ring heating device Furthermore, this design can only cook one dish at a time in a meal.

In each of the examples cited below, each product attempted to reference the functionality mentioned above, but as expected, none of the products mentioned fully achieved the goal.

In the patent document of U.S. Patent No. 4,214,517, a device for making bread and the like, such as buns, is described. It is made in the die hole of this device. A heated central die occupies the entire heating die Half, be used for making this bun, so just make it impossible to make the food of other shapes except the bun of this particular shape, in addition, the structure of this device is also unfavorable for cleaning.

A "uniform heating cooker" is described in US Patent No. 5,092,229. This device consists of numerous containers, vacuum tubes, standards and pads, which are used to average the air pressure and temperature generated during the cooking process, and evenly heat a variety of foods, somewhat similar to a pressure cooker. Although this product is very successful in this regard, the structure is too complicated, consisting of countless small components, and the user needs to be trained to operate. And due to the complexity of the product, the product is not easy to clean. Additionally, the product is a notoriously dangerous product due to the potential threat of exposing consumers to high-temperature steam during the cooking process.

In the patent document of U.S. Patent No. 5,794,525, a food cooker is described. This device contains a heater, and a cooking container can be placed on the heater. The shell has an opening at the top and a protruding part at the bottom, and a steam passage is arranged inside, and the outlet of the steam passage is slightly higher than the opening position on the top of the cooking container shell, and the opening position is provided with a cover. The heater has a base similar to a cooking vessel, and inside the base is a water container that is pre-filled with the required amount of water. There are heaters around the vessel to heat the water to produce steam. As we have seen, this device lacks a heating source that can generate heat in the middle of the container, and relies on water vapor to generate heat. The diversification of product function with regard to restriction like this makes it can only be used as a steamer. In addition, there is a potential fire hazard if the water level drops below the bottom due to excessive evaporation.

In the patent document of U.S. Patent No. 6,130,416, a food heating device is described, which connects sandwich ovens or grills together with hinges equipped with heaters, and then uses heat dissipating bodies to transfer heat to other parts of the device fixed. Comes with a removable plate so that food can be heated through the radiator. This design heats and toasts sandwiches evenly, and it can also be used as a grill for toasting other foods, but it cannot be used for stewing, cooking, etc. due to its lack of pots and cooking vessels. Soup or make casseroles. The detachable dish is easy to lose and requires other aids to remove the dish. This device also does not have a central heating setting, and the heating process of the food is also from the outside to the inside.

In the patent document of US Patent No. 6,320,166, a cooking pot-shaped container with a cover is briefly described. This container has a double wall structure, so that a heater can be added in the space between the two walls. But this food cooker, in addition to the cost increase caused by the complicated structure of the silicone oil-filled double wall, also has a potential safety threat brought by the 500-degree Fahrenheit temperature of the silicone oil in the double-wall cavity inside. There is no mention here of the precautions taken against the design of cooking food in the middle of such a container with hot liquid around it.

Described in the patent document of U.S. Patent No. 6,575,082 is a design about adopting an air roaster to replace a barbecue grill. Although there is an idea in this design to use the heat of a chimney in the center of the food to reduce the cooking time, there is a lack of a design in the design. A heat source placed in the middle of the food that can participate in the cooking of one or more serving containers. And this design is mainly used for barbecue, not convenient for home kitchen.

According to the design described above, we lack a product with full function, which must be able to control the temperature and evenly heat the food. At the same time, this product must have sufficient safety guarantees, and boiled water, high-pressure steam, and some ultra-high temperature conduction liquids should not be used. Furthermore, this product also needs to have a central heat source, which can be applied to one or several food pans, and can freely select the food in which pans to heat. In addition, this device has the function of being able to place multiple food pots, and can heat or cook multiple kinds of food at the same time.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the utility model food cooker is described in further detail:

The accompanying drawing is a part of this specification document, and is used to describe the whole process to explain the principle of the invention.

As shown in Figures 1, 2, and 3, the food cooker described in the utility model includes a central axis 11, a cooking container 12, a base 14, a heating element 15, a hole 18, a bottom surface 23, an inner cooking container 28, and an upper surface. 29. Central hole 37.

A brief description of the appearance of the design drawings, as shown in Figures 1-4, shows various manifestations of the food cooker 10.

As shown in FIG. 1 , when the base 14 is combined with the cooking container 12 , the hole 18 at the bottom of the cooking container 12 is fitted into the heating element 15 protruding from the base 14 . The heat provided by the heating element 15 in the figure is transferred to the heating device 16, the heating device is a common cylindrical body, and its shape matches the bottom hole of the cooking container 12, and the holes at the bottom of all cooking containers are similar to 12 in the figure , so that the cooking container can be smoothly connected with the base 14. In this way, the heating element, the cooking vessel, the base, etc. can form a complete whole, and the cooking vessel is all replaceable.

As shown in FIG. 2 , the food cooker 10 has a cooking vessel 12 inside which is a cooking space 27 . The cooking vessel 12 has a cylindrical shape, forming side walls 21 and forming a rounded vessel rim 19 at the top, so that food to be cooked can be placed in or taken out of the cooking space 27 .

The cooking vessel shown in FIG. 2 is the same as in all other food cookers 10 , the central axis 11 is formed by the middle wall 25 with the bottom surface 23 upward and the top wall 33 at the end of the middle wall 25 . The cooking container 12 thus forms a side wall 21 and a bottom surface 23 , and together with the middle wall 25 forms a cooking space 27 inside the cooking container 12 . The middle wall 25 and the top wall 33 form the cavity 18 of the central axis 11 of the cooking container 12 , and a hole 35 is formed on the bottom surface 23 of the cooking container 12 . The cavity 18 of the cooking vessel is fitted with a central heating body 15 protruding from the planar surface 29 of the base 14 and containing the heat source 16, the cooking vessel 12 can be freely removed or attached.

With these configurations, as long as the cavity 18 of the cooking container 12 can match the size of the heating element 15 on the base 14, it can be connected to the base 14 to cook or keep food warm. The cooking vessel can also be removed from the base 14 for cleaning, or to hold food. No matter be small or big or the cooking container 12 of special shape, all can be placed on the heating element that middle part promotes on the pedestal in the same way. In this way, the heat conducted from the heating element at the axial position of the base can be conducted to the food placed in the cooking container 12 .

The cooking container 12 among Fig. 2 emphatically shows the heating element 15 that can lift above the base 14, and the holes 18 that match it, so that the heat can be transferred to the cooking container 12, and the food that is positioned in the cooking container space 27 Heating is carried out, and the heat transferred from the heating element on the plane surface 29 of the base 14 can also balance the heating degree of the food simultaneously.

Here, the top wall 33 of the cooking vessel bottom cavity is located just below the lid 20 of the cooking vessel 12 and its rim 19 . Like this, can place second cooking container 28 in the position of central shaft 11, promptly inner cooking container 28, simultaneously this cooking container bottom also has a hole 31, and this container then can be connected with the top of central shaft 11. In some special designs of the food cooker 10, the second cooking container 28 is also designed so that it can be removed from the top wall 33, and the inner cooking container 28 is also engaged with the other parts of the product with the main cooking container. 12 is engaged with the base 14, the central cavity 37 of the inner cooking vessel cooks food from the heat transferred from the heating element on the food base 14 through the main cooking vessel cavity 18 in contact with the central axis 11. If the inner cooker is removable, the inner cooker can be used either to keep food warm during cooking or as a separate food cooker. If the food cooker 10 is used to keep other foods warm while cooking, then this inner cooking container 28 is indeed an excellent choice, and it can be placed on or around the central axis of the main cooking container so that it can be placed in the main cooking container. While the cooking container 12 is cooking, the food related to the staple food, such as soup, seasoning or second course food, is kept warm.

If the second cooking container 28 is connected with the main cooking container 12 and cannot be taken off, then these two cooking containers can be considered as a whole, and the main cooking container without the second cooking container 28 can also be equipped on the base 14. container12. If removable, the second cooking container 28 can be directly engaged with the cavity 18 of the main cooking container 12 temporarily. Further, the second cooking vessel 28 will be able to engage the main cooking vessel 12 of any shape and size as long as they fit on the same base and have a central wall 25 of the same size suitable for the inner cooking vessel. This allows the inner cooking container 28 to be compatible with a variety of different main cooking containers 12 . In all food cookers 10 containing the inner cooking container 28, the cavity 18 formed by the middle wall 25 is located in the center of the cooking container 12, so that the inner cooking container 28 is placed in its central position, and the handles 34 and 36 are used for The movement or other handling of the cooking vessel 12 and its lid 20 during or before or after cooking the food. And the height of cooking container 28 will not surpass the height of cooking space 27, the lid of main cooking container just can cover like this.

The design in FIG. 4 has another advantage. The central axis 11 is provided with a conical wall surface adapted to the heating element 15 . Find in the experiment, if the upper part of central heating element 15 is changed into conical shape, and the hole 18 of main cooking container 12 is also changed into same shape, the heat that sends out from the central part of cooking container 12 just can be more so. Well spread out. Simultaneously, this conical shape can also increase the contact area between the food and the heating element more than the cylindrical shape shown in FIG. 3 . In addition, the inner cooking container 28 is also easier to fit into the cavity 18 of the main cooking container, because the conical inclined surface can better align the center position and increase the area for receiving and transferring heat energy. When the cone-shaped inclined surface of the upper part of the heating element 15 is in contact with the central hole of a similar shape, the heat dissipated can be better transferred to the corners of the cooking container, and the dissipated area is also increased.

The heating element 15 in the central part is cylindrical in Fig. 1 and Fig. 3, but conical in Fig. 4 . Undoubtedly, such a design technique can also change the heating element 15 into other various shapes, as long as it can match the cavity 18 of the cooking vessel. When adding the second cooking container 28, its conical shape or the cylindrical shape in Fig. 3 also enables the second container to increase the heating area.

On the side wall 21 of the cooking container 12 there is a removable cover 20 which can cover the entire cooking space 27 . A central heating element 15 is mounted on the base 14 , and a protruding heating element 16 is mounted on the central heating element 15 . Similarly, a detachable cooking container 12 can also be connected to the base 14, and the cooking container 12 can be positioned on the outer surface 29 of the base. The heating device 16 is connected to the central heating element 15, so that heat energy can be transferred to the food from the middle position of the cooking container, and the bottom of the container can also receive uniform heat. The heating part of the central assembly can cook all the food, or the cooking container 12 can be raised slightly to keep a little distance from the surface of the base, so that it can be ensured that the food in the cooking container space 27 is Heat from its center.

The heat emitted from the heating element 15 can be realized in various ways, such as using electric heating, using a heater 26 or using a thermistor 32 specially designed for the food cooker 10 . Thermostat 22 and timer 30 enable more precise cooking. This thermostat mode can keep the heater 26 in a constant temperature state. It is very convenient to use the food heat preservation function of the food cooker 10 or the function of keeping the food at a certain fixed temperature for a certain period of time. When the temperature exceeds the temperature set by the temperature regulator 22, the heater 26 or the thermistor 32 will automatically cut off the power supply. Power is delivered via wires and a connector 24 that is sized appropriately for the power source.

The base 14 transmits electric power to the heating element 16 through the electric wire 24 , and after generating heat, the heat energy is transferred to the cooking space 27 of the cooking container 12 through the central hole 18 and the central heating element 15 of the cooking container 12 .

Generally, when the main cooking container 12 receives heat energy transmitted through the cooking space 27 , the top will be covered with the lid 20 . The cooking container 12 is located on the surface 29 of the base 14, and the size of the hole 18 is consistent with the outer diameter of the central heating element 15, so that the position can be well fixed. The best situation is that the main cooking container can be connected to the base very smoothly, and at the same time it can not be easily disengaged, and can transfer heat most efficiently.
