[0055] At present, if the dishes washed by the dishwasher are not used for a long time, the undried water in the dishwashing cavity may become damp, produce odor and breed bacteria. To solve the above problems, the relevant technology usually adds an additional blower mechanism. However, in some specific cases where the dishwasher is integrated with other home appliances, there is no solution that can solve this problem by linking the dishwasher with other home appliances.

[0056] Based on this, the embodiment of the present application provides a kitchen integrated system, which can use the high-temperature exhaust gas of the compressor to dry and disinfect the dishwasher, thereby reducing the cost of using a heating device. Figure 5 As shown, a schematic diagram of the structure of a kitchen integrated system provided by the present application is shown. The system includes: a dishwasher 500, a rack 501, a compressor 502, a refrigerant pipeline 503, an electronic expansion valve 504 and an exhaust temperature sensor 505. Among them, the dishwasher 500 has a dishwashing cavity, and the dishwasher is configured to clean and disinfect the tableware placed in the dishwashing cavity. The rack 501 is arranged in the dishwashing cavity and is configured to place the tableware placed in the dishwashing cavity. The compressor 502 is arranged outside the dishwashing cavity and is configured to generate high-temperature exhaust. The refrigerant pipeline 503 is at least partially arranged in the dishwashing cavity. One end of the refrigerant pipeline 503 is connected to the exhaust port of the compressor 502, and the other end is connected to the air inlet of the compressor 502. The electronic expansion valve 504 is arranged on the refrigerant pipeline whose one end of the exhaust port of the compressor 502 is connected to the dishwashing cavity, and is configured to adjust the exhaust pressure entering the dishwashing cavity. The exhaust temperature sensor 505 is disposed at the exhaust port of the compressor 502 and is configured to obtain the exhaust temperature of the compressor 502. The compressor 502 can be a compressor of a kitchen air conditioner or other household appliances, that is, the kitchen air conditioner or other household appliances are integrated with the dishwasher. In addition, a temperature sensor and a cleanliness sensor are also provided in the dishwasher 500, which are used to collect the temperature and cleanliness in the dishwashing cavity, respectively. The kitchen integrated system also includes a device for disinfection. The device for disinfection includes a processor and a memory, and the processor can implement a disinfection method for the dishwasher when executing.

[0057] Combine the following Figure 1 The present invention provides a method for disinfecting a dishwasher. The method for disinfecting a dishwasher includes:

[0058] S101. The processor receives an operation instruction from the dishwasher and controls the compressor to start running.

[0059] S102. The processor opens the electronic expansion valve so that the exhaust gas of the compressor can enter the dishwashing chamber.

[0060] S103. The processor obtains the temperature inside the dishwashing chamber.

[0061] S104. The processor adjusts the running frequency of the compressor and / or the opening degree of the electronic expansion valve to increase the temperature inside the dishwashing chamber.

[0062] In this embodiment, first, after the dishwasher washes the tableware, it sends an operation instruction to the kitchen integrated system. After receiving the operation instruction, the processor of the kitchen integrated system controls the compressor to start running. Of course, after washing the tableware, it is also possible to first send an instruction to the user asking whether to start sterilization and disinfection. After the user confirms the need for sterilization and disinfection, then start the compressor to run. Further, the compressor will open the electronic expansion valve and control it to remain at a certain opening degree, so that the exhaust gas of the compressor can enter the dishwashing chamber. At the same time, the processor will obtain the temperature inside the dishwashing chamber through the temperature sensor set in the dishwasher. Then, by adjusting the running frequency of the compressor and / or the opening degree of the electronic expansion valve, the temperature inside the dishwashing chamber is increased to sterilize and disinfect the dishwashing chamber. In this application, after the dishwasher finishes washing the internal tableware, through the refrigerant pipeline between the compressor and the dishwasher, the high-temperature exhaust gas generated by the compressor is introduced into the dishwasher for disinfection and odor removal. Therefore, compared with the method of continuously heating the air blown into the dishwasher by the heating device, the high-temperature exhaust gas of the compressor is used to dry and disinfect the dishwasher, reducing the cost of using the heating device.

[0063] Optionally, the step of adjusting the running frequency of the compressor and / or the opening degree of the electronic expansion valve includes: when t < T and T - t > t1, the processor keeps the opening degree of the electronic expansion valve unchanged and adjusts the running frequency of the compressor. When t < T and t2 < T - t < t1, the processor keeps the running frequency of the compressor unchanged and adjusts the opening degree of the electronic expansion valve. Wherein, t is the current temperature inside the chamber, T is the target temperature, t1 is the first temperature threshold inside the chamber, and t2 is the second temperature threshold inside the chamber.

[0064] In this embodiment, two different adjustment methods are divided by the temperature threshold t1 in the first cavity. During the sterilization process, the current temperature t in the cavity must be lower than the target temperature T. Therefore, by setting a temperature threshold t1 in the first cavity, when T - t > t1, it indicates that the current temperature in the cavity is low and cannot meet the sterilization requirements. Therefore, it is necessary to adjust the operating frequency of the compressor to quickly increase the compressor temperature. When t2 < T - t < t1, it indicates that the difference between the current temperature in the cavity and the target temperature is small. At this time, it is necessary to finely adjust the temperature in the cavity by adjusting the opening degree of the electronic expansion valve. This is more conducive to temperature control.

[0065] Optionally, the step of adjusting the operating frequency of the compressor includes: when T - t > t3, the processor increases the operating frequency of the compressor at the first speed V1. When t1 < T - t < t3, the processor increases the operating frequency of the compressor at the second speed V2. Wherein, t3 is the temperature threshold in the third cavity, and V1 > V2.

[0066] In this embodiment, the step of adjusting the operating frequency of the compressor to increase the temperature is further refined. On the basis of T - t > t1, t3 is also set to further distinguish the difference between the current temperature t in the cavity and the target temperature T. When T - t > t3, it indicates that the current difference is large and rapid heating is required. Therefore, the operating frequency of the compressor is increased at the first speed V1. When t1 < T - t < t3, the operating frequency of the compressor is increased at the second speed V2 which is lower than the first speed. By setting two different threshold levels and heating at different heating speeds, the heating efficiency is improved.

[0067] Combined with the above solution, as Figure 2 shown, another disinfection method for a dishwasher is provided. It includes:

[0068] S201, the processor determines whether T - t > t1. If not, it proceeds to S2021; if so, it proceeds to S2022.

[0069] S2021, when t2 < T - t < t1, the processor keeps the operating frequency of the compressor unchanged and adjusts the opening degree of the electronic expansion valve to increase the temperature in the washing cavity.

[0070] S2022, the processor determines whether T - t > t3. If so, it proceeds to S2031; if not, it proceeds to S2032.

[0071] S2031, the processor increases the operating frequency of the compressor at the first speed V1.

[0072] S2032, the processor increases the operating frequency of the compressor at the second speed V2.

[0073] In this embodiment, two different adjustment methods are divided by the temperature threshold t1 in the first cavity. Here, an example will be given to illustrate the solution of the present application. During the sterilization process, the current temperature t in the cavity must be lower than the target temperature T. Therefore, by setting a first temperature threshold t1 in the cavity, when T - t > t1, it indicates that the current temperature in the cavity is relatively low and cannot meet the sterilization requirements. Therefore, it is necessary to adjust the operating frequency of the compressor to quickly increase the temperature of the compressor. When t2 < T - t < t1, it indicates that the difference between the current temperature in the cavity and the target temperature is relatively small. At this time, it is necessary to finely adjust the temperature in the cavity by adjusting the opening degree of the electronic expansion valve. This is more conducive to temperature control. Further, the steps of adjusting the operating frequency of the compressor to increase the temperature are refined. On the basis of T - t > t1, t3 is also set to further distinguish the difference between the current temperature t in the cavity and the target temperature T. When T - t > t3, it indicates that the current difference is relatively large and rapid heating is required. Therefore, the operating frequency of the compressor is increased at the first speed V1. When t1 < T - t < t3, the operating frequency of the compressor is increased at the second speed V2 which is lower than the first speed. By setting two different threshold levels and heating at different heating speeds, the heating efficiency is improved.

[0074] For example, take t1 = 5°C, t2 = 0.5°C, and t3 = 15°C to introduce the solution of this embodiment. When the current temperature in the cavity is lower than the target temperature and the difference is more than 15°C, that is, the case of T - t > t3, the frequency of the compressor is increased at the first speed V1 to make the exhaust temperature rise faster. When the current temperature in the cavity is lower than the target temperature and the difference is between 5°C and 15°C, that is, the case of t1 < T - t < t3, the frequency of the compressor is increased at the second speed V2 which is lower than the first speed to make the exhaust temperature rise. When the current temperature in the cavity is lower than the target temperature and the difference is between 0.5°C and 5°C, that is, the case of t2 < T - t < t1, the opening degree of the electronic expansion valve is adjusted to finely adjust the exhaust temperature.

[0075] Optionally, the disinfection method for the dishwasher further includes: the processor obtains the cleanliness C of the dishwashing cavity. When the cleanliness C of the dishwashing cavity is greater than or equal to the preset cleanliness C s the compressor is shut down, and / or, the electronic expansion valve is closed.

[0076] In this embodiment, the cleanliness sensor will detect the cleanliness in the dishwashing cavity. When the detected cleanliness is greater than the preset cleanliness threshold, it indicates that the current cleanliness of the dishwashing cavity meets the requirements, and then the compressor is shut down and / or the electronic expansion valve is closed. This can save more energy.

[0077] Optionally, when the cleanliness C of the dishwashing cavity is less than the preset cleanliness C sIn the case of the above, the processor continues to adjust the operating frequency of the compressor and / or the opening of the electronic expansion valve until the cleanliness C of the dishwashing cavity is greater than or equal to the preset cleanliness C s In this embodiment, if the cleanliness is less than the preset cleanliness, the operating frequency of the compressor and / or the opening of the electronic expansion valve are continuously adjusted until the cleanliness C of the dishwashing cavity is greater than or equal to the preset cleanliness C. s . Thereby ensuring the sterilization effect.

[0078] Combination Figure 3 As shown, another method for disinfecting a dishwasher is provided. The method comprises:

[0079] S301, the processor receives an operation instruction from the dishwasher and controls the compressor to start running.

[0080] S302, the processor opens the electronic expansion valve to allow the compressor exhaust to flow into the dishwashing chamber.

[0081] S303, the processor obtains the temperature inside the dishwashing cavity.

[0082] S304, the processor adjusts the operating frequency of the compressor and / or the opening of the electronic expansion valve to increase the temperature inside the dishwashing cavity.

[0083] S305, the processor obtains the cleanliness C of the dishwashing cavity.

[0084] S306: The processor checks that the cleanliness C of the dishwashing cavity is greater than or equal to the preset cleanliness C s In such case, shut down the compressor and / or close the electronic expansion valve.

[0085] In this embodiment, the cleanliness sensor detects the cleanliness of the dishwashing cavity. When the cleanliness is detected to be greater than the preset cleanliness threshold, it means that the current cleanliness of the dishwashing cavity meets the requirements, and the compressor is shut down and / or the electronic expansion valve is closed. This saves more energy. On the contrary, if the cleanliness is less than the preset cleanliness, the operating frequency of the compressor and / or the opening of the electronic expansion valve are continuously adjusted until the cleanliness C of the dishwashing cavity is greater than or equal to the preset cleanliness C. s . Thereby ensuring the sterilization effect.

[0086] Optionally, the disinfection method for a dishwasher may also include exhaust protection for the compressor, which specifically includes: the processor obtains the compressor exhaust temperature E. When E>E1, the processor reduces the compressor operating frequency; wherein E1 is a first exhaust temperature threshold.

[0087] In this embodiment, the exhaust protection of the compressor is mainly reflected. Normally, the temperature of the compressor should not exceed 130°C to 150°C. Therefore, by setting the first exhaust temperature threshold E1, when the exhaust temperature E is higher than E1, the operating frequency of the compressor should be appropriately reduced, thus reflecting the protection of the compressor.

[0088] Optionally, the specific steps for reducing the operating frequency of the compressor include: when E1 < E < E2, reducing the operating frequency of the compressor at the third speed V3; when E2 < E < E3, reducing the operating frequency of the compressor at the fourth speed V4; when E > E3, controlling the compressor to stop running. Wherein, E2 is the second exhaust temperature threshold, E3 is the third exhaust temperature threshold, and V3 < V4.

[0089] In this embodiment, the steps of the exhaust protection process are further refined. For example, take E1 = 90°C, E2 = 95°C, and E3 = 100°C. When the exhaust temperature is greater than 90°C, the operating frequency of the compressor should be reduced at this time. When it is within the range of 90°C to 95°C, the operating frequency of the compressor is reduced at the third speed; when it is within the range of 95°C to 100°C, the operating frequency of the compressor is reduced at the fourth speed, and the fourth speed is greater than the third speed. When the exhaust temperature is greater than 100°C, the compressor needs to stop running. It should be noted here that in actual situations, when the exhaust temperature is greater than E3, it is necessary to first operate stably for a short period of time. For example, after running continuously for one minute, then shut down the compressor. This is to prevent the compressor from being easily damaged due to sudden shutdown, thus reflecting the exhaust protection of the compressor and improving safety.

[0090] Combined Figure 4 As shown, in the above embodiment, the disinfection method for the dishwasher further includes:

[0091] S401, the processor obtains the compressor exhaust temperature E.

[0092] S402, the processor determines whether E > E2. If not, it enters S4031; if so, it enters S4032.

[0093] S4031, when E1 < E < E2, the processor reduces the operating frequency of the compressor at the third speed V3.

[0094] S4032, the processor determines whether E > E3. If so, it enters S4041; if not, it enters S4042.

[0095] S4041, control the compressor to stop running.

[0096] S4042, reduce the operating frequency of the compressor at the third speed V3.

[0097] In this embodiment, the exhaust protection process of the compressor is mainly reflected. Normally, the compressor temperature should not exceed 130℃~150℃. Therefore, by setting the first exhaust temperature threshold E1, when the exhaust temperature E is higher than E1, the operating frequency of the compressor should be appropriately reduced. Thus, the protection of the compressor is reflected. For example, take E1=90℃, E2=95℃, E3=100℃. When the exhaust temperature is greater than 90℃, the operating frequency of the compressor should be reduced at this time. When it is within the range of 90℃~95℃, the compressor operating frequency is reduced at the third speed; when it is within the range of 95℃~100℃, the compressor operating frequency is reduced at the fourth speed. And the fourth speed is greater than the third speed. When the exhaust temperature is greater than 100℃, the compressor needs to be stopped to continue running. It should be noted here that in actual situations, when the exhaust temperature is greater than E3, it is necessary to run stably for a short period of time. For example, after running continuously for one minute, the compressor is shut down. In order to prevent the compressor from being easily damaged by sudden shutdown, the exhaust protection of the compressor is reflected, which improves safety.
