For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0033] Example 1

[0034] According to an embodiment of the present invention, a cooking utensil is provided. Figure 1 is a schematic diagram of a cooking appliance according to an embodiment of the present invention, such as Figure 1 As shown, the cooking appliance includes:

[0035] The temperature sensor 102 is used to obtain the current temperature of the inner cavity of the cooking appliance.

[0036] The temperature sensor may be a thermocouple or a thermal resistor.

[0037] The cooling device 104 is provided in the inner cavity of the cooking utensil and is used to cool the cooking utensil.

[0038] Optionally, the cooling device includes: a cooling water channel, which is arranged outside the inner cavity of the cooking appliance.

[0039] The cooling device can be a tubular radiator, a fin radiator, an air cooler, or a water cooler. The water cooler can be a cooling water channel, which can be a condensing water channel. Condensed water refers to liquid water formed by the condensation of gaseous water. The cooling device can also be a fan, with the fan speed controlled based on the target temperature and the current temperature. The cooling device can achieve rapid cooling of cooking utensils.

[0040] The controller 106 is connected to the temperature sensor and is used to obtain the target temperature of the inner cavity of the cooking appliance and control the working state of the cooling device based on the target temperature and the current temperature.

[0041] Among them, the controller is divided into a combinational logic controller and a microprogram controller, which is not limited here; the inner cavity of the cooking utensil refers to the internal space of kitchen appliances such as a steamer, oven, and steam oven, where food to be cooked is placed; the target temperature is the temperature of the inner cavity of the cooking utensil corresponding to the current working state of the cooking utensil; the current temperature can be the real-time temperature of the inner cavity of the cooking utensil collected by the temperature sensor; the working state of the cooling device can be that the cooling device is turned on to cool the cooking utensil, or the cooling device is turned off to stop cooling the cooking utensil.

[0042] The target temperature in the above steps can be the temperature that the cooking appliance cavity needs to maintain in the current operating state. It can be a pre-set temperature for different operating states, or it can be modified according to the user's actual needs. The current operating state can be the cooking appliance's on / off state, or it can be an operating mode of the cooking appliance, such as baking mode or steaming mode. For example, the target temperature corresponding to steaming mode can be 100°C.

[0043] The working state in the above steps may be that the cooling device is turned on to cool the cooking utensil; or, the cooling device may be turned off to stop cooling the cooking utensil.

[0044] In an optional embodiment, when it is detected that the current temperature is greater than the target temperature, it means that the current temperature inside the cooking utensil is too high and needs to be cooled down. At this time, the cooling device can be started to lower the current temperature. When it is detected that the current temperature is less than or equal to the target temperature, it means that the current temperature inside the cooking utensil is not high and does not need to be cooled down. Therefore, the cooling device can be turned off to avoid the low temperature inside the cooking utensil affecting the normal cooking process.

[0045] In another optional embodiment, if the difference between the current temperature and the target temperature is less than a set value (which can be set by the user), the difference between the real-time temperature of the inner cavity and the target temperature is small, the temperature of the cooking appliance is not high, and cooling is not required, so no control signal is issued to activate the cooling device. If the difference between the current temperature and the target temperature is greater than the set value, the difference between the real-time temperature of the inner cavity and the target temperature is large, the temperature of the cooking appliance is high, and cooling is required. Therefore, by determining whether to activate the cooling device based on the difference between the current temperature and the target temperature, inefficient energy consumption is avoided.

[0046] In an embodiment of the present invention, the target temperature and current temperature of the inner cavity of the cooking utensil can be obtained first, and then the working state of the cooling device can be controlled based on the target temperature and the current temperature, thereby realizing controlling the working state of the cooling device according to the real-time temperature of the inner cavity of the cooking utensil, cooling the cooking utensil by the cooling device, ensuring that the temperature of the inner cavity of the cooking utensil is maintained below the target temperature, avoiding the high temperature of the cooking utensil cabinet, achieving the technical effect of quickly cooling the cooking utensil and improving the safety of the cooking utensil, and thus solving the technical problem of the high temperature of the cooking utensil cabinet in the prior art.

[0047] Optionally, the cooling water circuit includes: a first solenoid valve, arranged at the water inlet of the cooling water circuit, for controlling the opening or closing of the cooling water circuit; a controller, connected to the first solenoid valve, for controlling the first solenoid valve to work when the current temperature is greater than the target temperature, and controlling the first solenoid valve to stop working when the current temperature is less than or equal to the target temperature.

[0048] The first solenoid valve in the above steps can be any one of a direct-acting solenoid valve, a distributed direct-acting solenoid valve, a pilot-operated solenoid valve, etc. The type of the first solenoid valve is not limited here.

[0049] In an optional embodiment, it can be determined whether the current temperature is greater than the target temperature. If the current temperature is greater than the target temperature, it means that the temperature of the inner cavity of the cooking appliance is too high. At this time, the first solenoid valve can be controlled to work, and the cooling device is turned on by the first solenoid valve to cool the inner cavity of the cooking appliance, so that the inner cavity of the cooking appliance can reach the target temperature and meet the user's usage needs; if the current temperature is less than or equal to the target temperature, it means that the temperature of the inner cavity of the cooking appliance does not need to be cooled anymore. At this time, the first solenoid valve can be controlled to stop working, and the cooling device is closed by the first solenoid valve to stop cooling the inner cavity of the cooking appliance, so as to reduce the power consumption of the cooking appliance.

[0050] Optionally, the controller is further configured to detect whether the working state of the cooking appliance has changed, and if it is detected that the working state of the cooking appliance has changed, obtain the target temperature and the current temperature.

[0051] The change in the working state in the above steps can be a transition between working modes. For example, it can be converted from baking mode to steaming mode, or from steaming mode to baking mode, or from the first baking mode to the second baking mode, wherein the temperature of the first baking mode is higher than that of the second baking mode; the change in the working state can also be a transition between the start and end of cooking of the cooking appliance, for example, the cooking appliance switches from starting cooking to ending cooking.

[0052] In an optional embodiment, when it is detected that the cooking appliance is switched from a higher temperature baking mode to a lower temperature baking mode, it indicates that the working state at this time has changed. The working state of the cooling device can be determined based on the real-time temperature of the inner cavity and the target temperature corresponding to the lower temperature baking mode. When the real-time temperature is greater than the target temperature, the cooling device is started to cool down; when the real-time temperature is less than or equal to the target temperature, the cooling device is turned off.

[0053] Optionally, the controller is also used to detect whether the cooking appliance has finished cooking, wherein if the cooking appliance has finished cooking, it is determined that the working state of the cooking appliance has changed; detect whether the working mode of the cooking appliance has changed, wherein if the working mode has changed, it is determined that the working state of the cooking appliance has changed.

[0054] In an optional embodiment, whether the working state of the cooking appliance has changed can be determined by detecting whether the cooking appliance has finished cooking. Specifically, whether the cooking appliance has finished cooking can be determined by determining whether the cooking operation duration of the cooking appliance has reached a preset cooking duration. If the cooking operation duration reaches the cooking duration, it is determined that the cooking appliance has finished cooking, i.e., the working state has changed. If the cooking operation duration does not reach the cooking duration, it is determined that the cooking appliance is still cooking, i.e., the working state has not changed.

[0055] In another optional embodiment, whether the working state has changed can be determined by detecting whether the working mode has changed. If the working mode has changed, for example, from baking mode to steaming mode, it is determined that the working state has changed; if the working mode has not changed, it is determined that the working state remains unchanged.

[0056] Optionally, the cooking appliance further includes: a steam generator, disposed outside the inner cavity, for providing steam to the inner cavity; and a controller, for controlling the steam generator to provide steam.

[0057] In the above steps, the steam generator includes an atmospheric pressure steam generator, a low pressure steam generator, a medium pressure steam generator, a sub-high pressure steam generator, an ultra-high pressure steam generator, a subcritical pressure steam generator, a supercritical pressure steam generator, and an ultra-supercritical pressure steam generator. The type of steam generator is not limited here.

[0058] In an optional embodiment, when the cooking appliance is in steaming mode, in order to ensure that the moisture content of the food does not decrease as the cooking time increases, a steam generator can be provided in the cooking appliance. When the inner cavity of the cooking appliance is relatively dry and the moisture content of the food is low, the steam generator can be controlled to provide steam to the inner cavity, thereby increasing the moisture content of the food.

[0059] Optionally, the cooking appliance also includes: a second solenoid valve, arranged on the first pipe connecting the cooling water circuit and the steam generator, for controlling the cooling water circuit to inject water into the steam generator; a controller, connected to the second solenoid valve, for controlling the operation of the second solenoid valve when the working mode is the steaming mode.

[0060] In the above steps, the water output of the cooling water circuit can control the steam generator to enter the operating state. When the water output of the cooling water circuit is greater than the preset water output, a control signal controls the steam generator to operate. The preset water output can be any of the following: the preset water output can be the water volume corresponding to the maximum volume of the steam generator; the preset water output can also be a preset value set by the user or the system; the preset water output can also be 0, that is, as soon as water is injected into the steam generator, the steam generator immediately begins to operate. The above three methods can be set according to actual needs. In this embodiment of the present invention, the preset water output is the water volume corresponding to the maximum volume of the steam generator as an example for explanation.

[0061] In an optional embodiment, in the steaming mode, steam needs to be provided to the inner cavity through the steam generator during the cooking process. In order to ensure the normal operation of the steam generator, water needs to be injected into the evaporator. At the same time, the cooling water in the cooling water circuit has a certain temperature after heat exchange. In order to avoid the waste of cooling water caused by direct discharge, the second solenoid valve can be controlled to work, and the cooling water circuit is controlled by the second solenoid valve to inject cooling water with a certain heat dissipation temperature into the steam generator for heating, so that the steam generator can quickly generate water vapor, thereby achieving the purpose of shortening the waiting time and fast steam endurance during continuous cooking, thereby achieving the technical effect of improving the utilization of heat.

[0062] Optionally, the cooling device includes: a third solenoid valve, arranged at the water outlet of a second pipe connected to the cooling water circuit, for controlling the cooling water circuit to drain water; a controller, connected to the third solenoid valve, for controlling the operation of the third solenoid valve when it is detected that cooking of the cooking appliance is finished.

[0063] In an optional embodiment, after cooking is completed, the third solenoid valve can be controlled to operate, and the cooling water channel can be controlled by the third solenoid valve to drain water. Draining excess water is beneficial to the cleaning of the cooking equipment and extending its service life. If it is detected that the cooling water channel drainage is completed, the cooking appliance automatically shuts down to reduce unnecessary waste of resources.

[0064] Optionally, the cooking appliance further includes: a fourth solenoid valve, arranged at the water inlet of the third pipe connected to the cooling water circuit, for controlling water injection into the cooling water circuit; and a controller, connected to the fourth solenoid valve, for controlling the operation of the fourth solenoid valve.

[0065] In an optional embodiment, the cooling water circuit is controlled to drain water before the cooking appliance is shut down. In order to ensure that the cooking appliance can cool down normally during the next cooking process, after the cooking appliance starts cooking, the fourth solenoid valve can be controlled to operate, and the cooling water circuit is controlled to be filled with water through the fourth solenoid valve.

[0066] It should be noted that during the cooking process, to ensure the normal circulation of cooling water in the cooling water circuit, the third and fourth solenoid valves must remain in operation. This means that cooling water is continuously injected and discharged from the cooling water circuit. Furthermore, while the third solenoid valve is controlling the discharge of cooling water from the cooling water circuit, the fourth solenoid valve must be deactivated.

[0067] Optionally, the cooking appliance further comprises: an output device for outputting a preset signal, wherein the preset signal is used to remind the user that the current temperature is less than or equal to the target temperature.

[0068] The output preset signal in the above steps can be presented in the form of an indicator light; it can also be presented by a specified sentence or symbol on an electronic screen; it can also be presented by playing a voice, in which case the preset signal can be an audio signal; it can also be presented by sending a preset signal to a communication device, so that the user can receive the signal even if they are temporarily away from home or attending to other matters. For example, a text message can be sent to the user to inform them of the real-time status of the cooking device, thereby improving the user experience.

[0069] In an optional embodiment, after the cooking appliance finishes working, if the current temperature of the cooking appliance is less than or equal to the target temperature in the current working state, a preset signal can be output to let the user know the real-time temperature of the inner cavity of the cooking appliance, thereby improving the user experience.

[0070] Optionally, the water pipe of the cooling water circuit is coiled outside the inner cavity of the cooking utensil.

[0071] In the above steps, the materials of the water pipes include metal materials and non-metal materials, and the material of the water pipes is not limited here.

[0072] Optionally, the cooling device further includes: a fan embedded in the inner cavity of the cooking appliance; and a controller connected to the fan for controlling the operation of the fan.

[0073] In an optional embodiment, since the water pipes of the cooling water circuit are coiled around the outside of the inner cavity of the cooking appliance, the cooling water circuit can cool the air close to the inner cavity wall of the cooking appliance. In order to achieve the purpose of rapid cooling, a fan can be set on the inner cavity to make the air inside the inner cavity flow, so that the temperature inside the inner cavity is quickly balanced.

[0074] Optionally, the cooling device further includes: a heat dissipation hole, which is arranged on the outside of the box of the cooking appliance; and a controller, which is connected to the heat dissipation hole and is used to control the operation of the heat dissipation hole.

[0075] There is no requirement for the shape of the heat dissipation holes in the above steps. The shape with the best heat dissipation effect is selected.

[0076] In an optional embodiment, heat dissipation holes may be provided on the wall of the inner cavity. By controlling the operation of the heat dissipation holes, the hot air in the inner cavity may be discharged in time, thereby further improving the cooling effect.

[0077] The following combination Figures 2 to 4 A preferred embodiment of the present invention is described in detail. Figure 4 As shown, the method may include the following steps:

[0091] Step S414, closing the cooling water circuit.

[0092] The cooking appliance in the above steps can be an ordinary cooking appliance or an intelligent cooking appliance, and its components include a temperature sensor, a cooling device, and a controller. Figure 2 As shown, the cooking appliance includes: a first solenoid valve 1, a second solenoid valve 2, a third solenoid valve 3, a fourth solenoid valve 4, a cooling water channel 7, a circulating fan 8 and a steam generator 9, wherein the first solenoid valve 1 is arranged at the water inlet of the cooling water channel 7, for controlling the opening or closing of the cooling water channel 7; the second solenoid valve 2 is arranged on the first pipe 10 connecting the cooling water channel 7 and the steam generator 9, for controlling the cooling water channel 7 to inject water into the steam generator 9; the third solenoid valve 3 is arranged at the water outlet 6 of the second pipe 20 connected to the cooling water channel 7, for controlling the cooling water channel 7 to drain water; the fourth solenoid valve 4 is arranged at the water inlet 5 of the third pipe 30 connected to the cooling water channel 7, for controlling the cooling water channel 7 to inject water; the cooling water channel 7 is coiled outside the inner cavity of the cooking appliance. Figure 3 As shown, the circulation fan 8 is embedded in the inner cavity of the cooking utensil; the steam generator 9 is arranged outside the inner cavity of the cooking utensil to provide steam to the inner cavity.

[0093] In a first optional embodiment, after the cooking appliance finishes cooking according to a certain working mode, the first solenoid valve, the third solenoid valve, the fourth solenoid valve and the inner cavity fan are opened, the cooling water circuit is opened, and the temperature sensor periodically detects the temperature of the inner cavity. When the current temperature T of the cooking appliance is greater than the target temperature T0, the cooling water circuit continues to be opened until the temperature of the inner cavity of the cooking appliance reaches T0, the fourth solenoid valve and the inner cavity fan are closed, the first solenoid valve and the third solenoid valve are kept open, and after the water in the water circuit is drained, the cooking appliance automatically shuts down.

[0094] In a second optional embodiment, the user uses the cooking utensil to bake and then steam. At this time, the working mode of the cooking utensil is switched from baking mode to steaming mode. The first solenoid valve, the third solenoid valve, the fourth solenoid valve and the inner cavity fan are opened, the cooling water circuit is opened, and the temperature sensor periodically detects the temperature of the inner cavity. When the current temperature T of the cooking utensil is greater than the steaming temperature T0 (100°C), the cooling water circuit continues to be opened until the temperature of the inner cavity of the cooking utensil reaches T0. The third solenoid valve, the fourth solenoid valve and the inner cavity fan are closed, and the first solenoid valve and the second solenoid valve are kept open. After a certain amount of cooling water after heat exchange is passed to the steam generator to the maximum volume, the steaming mode is turned on.

The fourth solenoid valve and the inner cavity fan are closed, and the second baking cooking is started. If the temperature T of the inner cavity of the cooking utensil is less than the temperature T0 of the second baking mode, the heating tube in the corresponding mode starts working, and after reaching the target temperature T0, the second cooking is started. After the second baking cooking is completed, cooking is no longer continued, and the first optional embodiment is executed, which is not described here.
