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 volumetric refrigeration scheme generally adopts the structures of a compressor, a condenser, an evaporator, a four-way valve, a one-way valve capillary tube assembly and the like, and enables the evaporator to be close to an inner pot of the electric cooker so as to transfer cold energy.
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 refrigeration assembly has the problems of oil cracking and the like. 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.

Namely, the water cooling assembly is used for providing water flow to the water flow channel 201 to cool the inner pot 102 by water cooling.
Meanwhile, as the liquid is directly contacted with the outer surface of the inner pan 102, the heat transfer effect is greatly improved, and the problem of poor heat transfer caused by the air gap between the evaporator and the inner pan 102 in the related technology is solved.

The working process of the cooking appliance is as follows: by inputting a temperature value into the temperature setting and status display board 1102 or selecting a preset function in the temperature setting and status display board 1102, a preset temperature value is provided in the function program, then the temperature setting and status display board 1102 transmits and stores a temperature setting signal into the control board 1101, the control board 1101 compares different temperature signals transmitted by the inner pot temperature sensor 1103 and the reservoir temperature sensor 1104, and then the water pump 106, the compressor 109 and the blower 117 are controlled to be turned on or turned off accordingly.
For example, when the temperature of the inner pot 102 is detected to be higher than the water temperature of the liquid storage tank 105 by more than 5 ℃, and the current temperature of the inner pot 102 is higher than the set temperature of the inner pot 102, the water pump 106 is controlled to start operation.

After the water pump 106 is started to operate for 0-10 min, the compressor 109 and the fan 117 are started to start refrigerating operation. When the water temperature of the liquid storage tank 105 is lower than the temperature of the inner pot 102 by less than 10 ℃, the water pump 106 stops running. When the temperature of the inner pot 102 is 0.5-1 ℃ lower than the set temperature of the inner pot 102 and is maintained for more than 10s, the compressor 109 is controlled to stop running, and the fan 117 is controlled to stop running after the compressor 109 is stopped for 15 s.
In order to better understand the working principle of the cooking appliance of the embodiment of the present invention, please refer to fig. 12, which illustrates the working sequence of the relevant components of the cooking appliance in detail with an embodiment. Fig. 12 is a timing chart of the operation of the cooking appliance, in which a in fig. 12 indicates a node where the water cooling unit is started after cooking is finished; b represents a node of starting the refrigeration assembly and powering off the water cooling assembly; c represents a node at which the refrigeration is finished and the compressor 109 is stopped; d node with fan 117 shut down.
Referring to fig. 12, it can be understood that, before the node a, the heating device 103 is continuously operated to perform a food cooking process, when the node a is reached, the cooking process is finished, the food in the inner pot 102 is processed and the temperature is highest, for example, 100 ℃, and the water pump 106 is at a high level at this time, which means that the water pump 106 is turned on, that is, the water cooling assembly is turned on, to deliver the liquid in the liquid storage tank 105 to the water supply pipe 107, and the liquid flowing out from the water supply pipe 107 is delivered to the water flow channel 201 through the water inlet 202 and flows to the outer surface of the inner pot 102 from the water outlet 203, so that the cooling energy is transferred to the inner pot 102, thereby cooling the food in the inner pot 102 and performing the rapid cooling function.
After the water pump 106 operates for a period of time, the water reaches the node B, at this time, the temperature of the food in the inner pot 102 is reduced to a certain range, for example, 30 to 70 ℃, and then the water pump 106 is controlled to be switched to a low level, that is, the water pump 106 stops working, and the water cooling assembly is in a power-off state. And, compressor 109 and fan 117 are in the high level, and compressor 109 and fan 117 start, and the refrigeration subassembly starts, and the evaporimeter butt is in heat conduction ring 104, and heat conduction ring 104 cover is located the outside of interior pot 102 to the cold volume that produces the refrigeration subassembly is transmitted to interior pot 102, and then the food in the interior pot 102 of cooling plays the refrigerated effect.
After the refrigeration assembly operates for a period of time, the temperature reaches the node C, at this time, the temperature of the food in the inner pan 102 is reduced to a set temperature, for example, the temperature is reduced to 20 ℃, then the compressor 109 is controlled to be switched to a low level, that is, the compressor 109 stops operating, the refrigeration function of the refrigeration assembly stops, the fan 117 continues to operate, the air inlet 118 serves as an inlet for cooling air, so that the cooling air can enter the air duct from the air inlet 118 and flow along the air duct, and when passing through the condenser 110, the heat of the condenser 110 is taken away, the heat exchange of the condenser 110 is accelerated, and under the driving of the fan 117, hot air obtained after heat exchange is discharged from the air outlet 119.
After the fan 117 operates for a certain period of time, for example, after the compressor 109 is stopped for 15S, the D node is reached, at this time, the temperature in the cooker body 101 is driven by the fan 117 to fall within the acceptable range, and the fan 117 also changes to the low level, that is, the fan 117 stops operating.

Referring to fig. 13, the control method according to the embodiment of the present invention includes, but is not limited to, step S1301, step S1302, step S1303, step S1304, step S1305, and step S1306.
Step S1301, a first signal is obtained, where the first signal is used to represent that the heating apparatus stops operating.
It will be appreciated that a temperature sensor may be provided at the bottom of the inner pot, and when the temperature of the inner pot reaches a set upper limit temperature, indicating that the food in the inner pot has been processed and the temperature is highest, the heating device stops operating and generates a first signal, i.e. the first signal may be a temperature signal.
It can also be understood that when the food in the inner pot is processed and the temperature is highest, the heating device stops operating, and then stops or enters into a heat preservation mode, which is a common control method for cooking appliances such as electric cookers. Therefore, the first signal of step S1301 may also be a signal generated by stopping the operation of the heating device, and generating the first signal after the heating device is powered off for a certain time, for example, after the heating device is powered off for one minute, that is, the first signal may be a time signal.
Step S1302, a first temperature is obtained and used for representing the temperature of the inner pot.

In step S1305, when the difference between the first temperature and the second temperature is less than or equal to the first set value, the water cooling module is controlled to be closed.
It can be understood that, when the difference between the first temperature and the second temperature is less than or equal to the first set value, for example, the temperature of the inner pot is higher than the water temperature of the liquid storage tank by within 3 ℃, it indicates that the difference between the water temperature of the liquid storage tank and the temperature of the inner pot is not large, the solution of the liquid storage tank is adopted for water cooling, so that the temperature of the inner pot is reduced less, the water cooling assembly is controlled to be closed, and the water cooling is finished, so that the energy can be saved.
It can be understood that when the water cooling assembly is closed, the first temperature is detected to be higher than the set temperature, which indicates that the set temperature of the inner pot is still lower than the current temperature of the inner pot at the moment, the compressor and the fan are controlled to start, and the refrigeration assembly starts to operate. Through the combination of water-cooling subassembly and refrigeration subassembly, pot temperature in the water-cooled mode can be reduced fast, and need not the long-time cooling of refrigeration subassembly, avoids compressor overload operation, improves refrigeration subassembly reliability.
It should be noted that, in some embodiments, the step S1304 may also be modified to control the water cooling assembly and the refrigeration assembly to start when the difference between the first temperature and the second temperature is greater than the first set value and the first temperature is higher than the set temperature. Correspondingly, step S1306 is cancelled. Namely, the two embodiments are different in that the water cooling assembly and the refrigerating assembly are started together when meeting the same condition or are started separately when meeting different conditions. Work together when water-cooling subassembly and refrigeration subassembly for refrigeration efficiency greatly promotes, is favorable to interior pot rapid cooling.

Step S1307, when the difference between the first temperature and the set temperature is smaller than the second set value and the first set time is maintained, the refrigeration component is controlled to be turned off.
It can be understood that, when the difference between the first temperature and the set temperature is less than the second set value, it indicates that the temperature of the inner pan is lower than the set temperature of the inner pan, for example, the temperature of the inner pan is lower than the set temperature of the inner pan by 0.5 ℃, and at this time, the cooling requirement of the cooking appliance may be met, or the temperature may be caused by temperature fluctuation or detection error, in order to make the control more accurate, therefore, it is further necessary to determine whether the first set time, for example, more than 10 seconds, can be maintained when the difference between the first temperature and the set temperature is less than the second set value, and at this time, it may be determined that the cooling requirement of the cooking appliance is met, and the cooling component is controlled to be turned off.

It can also be understood that when the food in the inner pot is processed and the temperature is highest, the heating device stops operating, and then stops or enters into a heat preservation mode, which is a common control method for cooking appliances such as electric cookers. Therefore, the first signal of step S1301 may also be a signal generated by stopping the operation of the heating device, and generating the first signal after the heating device is powered off for a certain time, for example, after the heating device is powered off for one minute, that is, the first signal may be a time signal.

And step S1504, controlling the refrigeration assembly to start when the running time of the water cooling assembly reaches a second set time.
