The cooking utensil refers to a device capable of converting electric energy into heat energy, such as an electric cooker, a pressure cooker and the like.

Electric rice cookers, also known as electric cookers and electric rice cookers. The electric cooker converts electric energy into heat energy, has various operation functions of steaming, boiling, stewing and the like on food, and is convenient to use, safe and reliable. The multifunctional cooking machine can cook food, can preserve heat, is clean and sanitary to use, has no pollution, saves time and labor, and is one of indispensable tools for modernization of housework.

Pressure cookers are also called pressure cookers and pressure cookers, and are also cookers for converting electric energy into internal energy. The physical phenomenon that the boiling point of liquid under higher air pressure can be improved is utilized to exert pressure on water, so that the water can reach higher temperature without boiling, and the efficiency of stewing food is accelerated.

In order to make the cooking utensil have the function of cold storage and fresh keeping, in the related art, some cooking utensils have a refrigerating device arranged in a pot body, the refrigerating device adopts a semiconductor refrigerating scheme, and the semiconductor refrigerating is a solid refrigerating mode and is realized by directly transferring heat in the movement of holes and electrons. The working principle of semiconductor refrigeration is based on the peltier effect. The semiconductor thermocouple is composed of an N-type semiconductor and a P-type semiconductor. The N-type semiconductor has excess electrons and a negative temperature difference potential. The P-type semiconductor has insufficient electrons and has positive temperature difference potential; when electrons travel from the P-type to the N-type through the junction, the temperature of the junction decreases, the energy thereof necessarily increases, and the increased energy corresponds to the energy consumed by the junction. Conversely, as electrons flow from the N-type to the P-type material, the temperature of the junction increases. Because the semiconductor refrigeration has no mechanical rotating part, no refrigerant is needed, no noise, no pollution, high reliability, long service life, reverse heating by current, easy constant temperature control and the like, the prior cooking utensil adopts more technical schemes of semiconductor refrigeration.

However, the refrigerating capacity of the semiconductor refrigeration is relatively small, and if the scheme of the semiconductor refrigeration is used for the cooking appliances such as the electric rice cooker, the temperature is reduced from high temperature, the cooling time is long, and the practicability is not high. Accordingly, in the related art, a volume type cooling scheme is used in a cooking appliance such as an electric cooker. The positive displacement refrigeration scheme generally adopts the structures such as a compressor, a condenser, an evaporator, a four-way valve, a one-way valve capillary tube assembly and the like.

The refrigeration working process is as follows: the compressor compresses refrigerant into high-temperature high-pressure liquid, the high-temperature high-pressure liquid is sent to the condenser to release heat, the high-temperature high-pressure liquid is subjected to pressure reduction and throttling through the expansion valve (capillary tube), the high-temperature high-pressure liquid enters the evaporator, the high-temperature high-pressure liquid is evaporated and absorbed in the evaporator to become superheated steam, the superheated steam returns to the compressor, the cold energy of the evaporator is transferred to the inner pot of the cooking utensil, and the reciprocating circulation is carried out, so that the purpose of cooling food in the inner pot is achieved.

In the related art, the solution of the positive displacement refrigeration has a plurality of problems to be solved. For example, on one hand, the evaporator is in close contact with the inner pot of the electric cooker, and the inner pot can generate high temperature during cooking (especially in a coil electromagnetic heating mode), and the high temperature is transmitted to the evaporator, so that the oil product cracking and other problems occur in a refrigeration system. On the other hand, because interior pot can load and unload, and the lateral wall of interior pot is vertical upwards to extend from the bottom of a boiler, consequently, has the air gap between interior pot and the evaporimeter, causes the heat transfer effect poor, and refrigeration efficiency is low.

With reference to fig. 1 to 14, how the cooking appliance according to the embodiment of the present invention solves the above problem will be described.

The refrigerating system comprises a compressor 104, a condenser 105, an evaporator 106 and a throttling device 107 which are mutually communicated, the evaporator 106 is abutted to the heat conduction ring 108, so that cold energy generated by the refrigerating system is transmitted to the inner pot 102, food in the inner pot 102 is cooled, a rapid cooling effect is achieved, the refrigerating system continuously keeps refrigeration, and refrigeration and fresh keeping of the food can be achieved.

The heat conduction ring 108 comprises a support section 505, the shape of the support section 505 corresponding to the shape of the inclined section 504, such that the support section 505 can conform to the inclined section 504. At least one section of the inner pan 102 and the heat conducting ring 108 have the same inclination angle in the relative vertical direction, namely, the inclination angle of the inclined section 504 of the inner pan 102 is the same as that of the supporting section 505 of the heat conducting ring 108, when the inner pan 102 is put down, the inner pan 102 is automatically and tightly attached to the heat conducting ring 108 under the action of gravity, so that the heat transfer distance between the inner pan 102 and the heat conducting ring 108 is smaller, the heat resistance is smaller, the heat exchange effect is further enhanced, and the refrigeration efficiency is improved.

It is understood that the contact position of the heat-conducting ring 108 and the evaporator 106 is provided with a heat-conducting silicone (not shown in the figure) for filling the gap between the evaporator 106 and the heat-conducting ring 108, so as to enhance the heat-conducting effect. Before the heat conductive silicone is used, a gap is formed between the contact portion of the heat conductive ring 108 and the evaporator 106, and the gap is filled with air, so that heat transfer between the heat conductive ring 108 and the evaporator 106 at the gap is carried out through air. The gap between the untouched interfaces is often filled with air and heat will travel through the gap layer in a thermally conductive and radiative manner, this additional resistance to heat transfer being referred to as contact resistance compared to the ideal true full contact. By arranging the heat-conducting silica gel at the contact position of the heat-conducting ring 108 and the evaporator 106, the contact pressure is increased, and the air between interfaces is filled with the interface material, so that the contact thermal resistance is reduced, and the heat transfer efficiency is improved. It is understood that a flexible thermal pad may be provided at the contact location of the thermal ring 108 and the evaporator 106.

Similarly, it will be appreciated that a flexible heat conducting gasket (not shown) is disposed between the inner pan 102 and the heat conducting ring 108 to increase the contact pressure and increase the interface material to fill the air between the interfaces, thereby reducing the contact resistance and improving the heat transfer efficiency. Specifically, the inner side of the heat conduction ring 108 is attached with a flexible heat conduction gasket with a certain thickness, so that no gap is generated between the inner pot 102 and the heat conduction ring 108, and a good heat conduction effect is formed. It can be understood that a flexible heat-conducting gasket with a certain thickness can be attached to the outer side of the inner pan 102 to fill the gap between the inner pan 102 and the heat-conducting ring 108, so as to enhance the heat-conducting effect.

Because interface materials such as heat-conducting silica gel and flexible heat-conducting gaskets are arranged between the inner pot 102 and the evaporator 106, no air gap exists, the heat-conducting property is good, and the cooling rate is high.

It can be understood that the outer side of the evaporator 106 is provided with a heat insulation layer with a certain thickness, the heat insulation layer is made of a high temperature resistant material, and by adopting the heat insulation layer, the evaporator 106 is prevented from being affected by the high temperature of the inner pot 102, so that the high temperature is prevented from being transferred to the evaporator 106, and the problem that the oil product is cracked due to the high temperature of the refrigeration system is solved.

It is understood that the material of the heat-conducting ring 108 may be a metal material with good heat-conducting property, such as aluminum or copper. Aluminum or copper has good thermal conductivity but poor magnetic conductivity. Because part cooking utensil adopts the electromagnetic heating mode, and cooking utensil's heating device 103 is provided with electromagnetic heating coil promptly, and the material of heat conduction ring 108 uses aluminium or copper, can be so that heat conduction ring 108 keeps good heat transfer performance simultaneously, avoids producing induction current and produces the induction heating effect, avoids evaporimeter 106 to receive the influence of high temperature, the oil cracking scheduling problem appears.

It can be understood that the cooking utensil further comprises a magnetic isolation plate (not shown in the figure), the magnetic isolation plate is located between the heating device 103 and the compressor 104, and the area of the magnetic isolation plate is enough to shield the whole heating device 103 and isolate an electromagnetic vortex generated by an electromagnetic coil in the heating device 103, so that the compressor 104 and other components are prevented from generating an induction heating effect and being heated and damaged. For example, the magnetic shield may be disposed 1cm to 3cm below the heating device 103. The magnetic shield may also be disposed at an upper portion or a side portion of the compressor 104.

It is understood that the evaporator 106 can be one of a round tube type heat exchanger coil, a square tube type heat exchanger coil, or a microchannel flat tube.

It can be understood that, the evaporator 106 includes the pipe body, the pipe body twines in heat conduction ring 108, in order to surround heat conduction ring 108 in circumference, make heat conduction of heat conduction ring 108 more even, and heat conduction ring 108 is provided with the concave part (not shown in the figure), the pipe body laminating is in the concave part, make the contact between evaporator 106 and the heat conduction ring 108 become the face contact by line contact, heat transfer area has been increased, and then heat exchange efficiency can be improved, reduce the clearance between evaporator 106 and the heat conduction ring 108 simultaneously, and then reduce the thermal contact resistance between evaporator 106 and the heat conduction ring 108.

Referring to fig. 5, it can be understood that the evaporator 106 is disposed separately from the heat conduction ring 108, and the tube body of the evaporator 106 is wound outside the heat conduction ring 108, so as to facilitate installation, adjustment and maintenance.

Referring to fig. 1 to 4, it can be understood that an insulating layer 109 is further disposed on the outer side of the evaporator 106, the insulating layer 109, the heat conduction ring 108 and the inner pan 102 enclose a relatively closed insulating space, and the evaporator 106 is disposed in the insulating space, so as to effectively prevent the dissipation of the cold energy of the evaporator 106, increase the utilization rate of the cold energy, and improve the heat exchange efficiency.

It should be noted that the evaporator 106 and the heat conduction ring 108 may also be integrated, the evaporator 106 is fixed or embedded in the heat conduction ring 108 by welding or casting, and the heat conduction ring 108 is a metal ring or a bracket.
