DETAILED DESCRIPTION

Description will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of illustrating the invention and are not to be construed as limiting the invention.
Referring to Figures 1 and 2 together, the control method of the embodiment of the present invention may be applied to a dishwasher 100. The dishwasher 100 includes a housing 110, a temperature detection unit 120, a heating device 130, and a first fan 140. The housing 110 is formed with a working chamber 111. The temperature detection unit 120 is configured for detecting the temperature of the working chamber 111. A heating device 130 and a first fan 140 are provided in the working chamber 111. The control method comprises the following steps:

S151: controlling the temperature detection unit 120 to detect the temperature after the dishwasher 100 finishes washing;
S152: determining whether the temperature is less than or equal to a first preset temperature; and
S153: controlling the heating device 130 and the first fan 140 to operate to establish an airflow which dissipates heat generated by the heating device 130 in the working chamber 111 when the temperature is less than or equal to the first preset temperature.

Referring again to Figure 2, the dishwasher 100 of the embodiment of the present invention includes a housing 110, a temperature detection unit 120, a heating device 130, a first fan 140, and a processor 150. The housing 110 is formed with a working chamber 111. The temperature detection unit 120 is configured for detecting the temperature of the working chamber 111. The heating device 130 and the first fan 140 are provided in the working chamber 111. The processor 150 is configured for:

controlling the temperature detection unit 120 to detect the temperature after the dishwasher 100 finishes washing;
determining whether the temperature is less than or equal to a first preset temperature; and
controlling the heating device 130 and the first fan 140 to operate to establish an airflow which dissipates heat generated by the heating device 130 in the working chamber 111 when the temperature is less than or equal to the first preset temperature.

That is, the control method of the embodiment of the present invention may be implemented by the dishwasher 100 of the embodiment of the present invention, wherein the steps S151, S152, and S153 may be implemented by the processor 150.
The control method of the dishwasher 100 and the dishwasher 100 of the embodiment of the present invention use the temperature detected by the temperature detection unit 120 to control the heating device 130 and the fan 140 to operate to establish the airflow with heat, thereby increasing the temperature of the working chamber 111, avoiding the problems of humidifying of the working chamber 111 and growth of bacteria, thereby improving the hygiene and sanitary condition for tableware such as bowls and dishes and the like to be stored in the dishwasher 100 after being washed.
In some embodiments, the temperature detection unit 120 includes a temperature sensor. In this way, the temperature can be quickly obtained using a temperature sensor.
As can be appreciated, when the temperature is relatively low, the water vapor in the dishwasher 100 easily condenses into water droplets, thereby adhering to the dishes, making the dishes moist and easy to breed bacteria, so that the heating device 130 and the first fan 140 can be controlled to operate, evaporating the water droplets and taking them out of the working chamber 111 by means of the airflow with heat.
In certain embodiments, the heating device 130 includes a heating tube. In this manner, the heating device 130 may be utilized to operate to generate heat.
In some embodiments, the first preset temperature is between 25 °C and 35 °C. In this way, it is ensured that the water vapor in the working chamber 111 is not easily condensed, and the energy consumption of the dishwasher 100 can be reduced.
Specifically, if the value of the first preset temperature is too small, such as less than 25 °C, the temperature of the working chamber 111 may be lower than 25 °C, and when the temperature of the working chamber 111 is lower than 25 °C, the water vapor in the working chamber 111 is easy to saturate and condense into water drops; if the value of the first preset temperature is too large, for example, greater than 35 °C, it is necessary to increase the operating time of the heating device 130 and the first fan 140 or to increase the operating power of the heating device 130 and the first fan 140, thereby increasing the energy consumption of the dishwasher 100. Accordingly, the first preset temperature may be set to 25 °C to 35 °C. In other embodiments, the first preset temperature may also be adjusted according to user requirements, for example, the first preset temperature may also be between 20 °C and 40 °C.
The working chamber 111, also called an inner container, may refer to a part of the dishwasher 100 where tableware can be placed and washed.
In some embodiments, the first fan 140 may be controlled to operate for a predetermined period of time before the temperature detection unit 120 detects the temperature, thereby making the temperature detected by the temperature detection unit 120 more accurate. Specifically, there is a deviation in the temperature detected by the temperature detection unit 120 due to uneven distribution of heat. For example, if the temperature detection unit 120 is disposed near the heating device 130, the temperature detected by the temperature detection unit 120 may be high, and if the temperature detection unit 120 is disposed far away from the heating device 130, the temperature detected by the temperature detection unit 120 may be low. Therefore, the first fan 140 can be controlled to operate for a preset period of time before the temperature detection unit 120 detects the temperature, so that the air in the working chamber 111 can be circulated, the heat of each position in the working chamber 111 is balanced, and the temperature detected by the temperature detection unit 120 is more accurate.
In some embodiments, temperature detection unit 120 may detect and obtain multiple temperatures and take an intermediate or average value of the multiple temperatures as the temperature of working chamber 111. Thus, the accuracy of the temperature can be guaranteed.
In some embodiments, when the temperature is greater than the first preset temperature, the temperature detection unit 120 may be controlled to detect the temperature after a first time interval, i.e., step S151 is re-executed after the first time interval. In addition, the heating device 130 and the first fan 140 can be controlled to keep the original state, that is, to keep operating if the heating device 130 and the first fan 140 were previously in the operating state, and to remain closed if the heating device 130 and the first fan 140 were previously closed.
Referring again to Figure 2, in some embodiments, the heating device 130 and the first fan 140 are disposed at a bottom of the working chamber 111.
In this manner, the airflow with heat created by the operation of the heating device 130 and the first fan 140 readily flows through the entire working chamber 111.
As can be appreciated, the density of the hot air is small, and the airflow with heat formed by the heating device 130 and the first fan 140 tends to rise upward, so that the heating device 130 and the first fan 140 are disposed at the bottom of the working chamber 111, so that the airflow with heat can flow through the whole working chamber 111, and water droplets in the working chamber 111 are evaporated and carried out of the working chamber 111.
In one embodiment, the first fan 140 is disposed adjacent to the heating device 130 such that the first fan 140 can blow heat generated by operation of the heating device 130 toward the working chamber 111.
Referring to Figure 3, in some embodiments, the control method includes the following steps before the dishwasher 100 finishes washing:
S154: controlling the dishwasher 100 to enter a washing process, a rinsing process, and a drying process.
Referring again to Figure 2, in some embodiments, the processor 150 is configured to control the dishwasher 100 to enter a washing process, a rinsing process, and a drying process.
That is, step S154 may be implemented by processor 150.
In this way, the dishwasher 100 can clean and dry the dishes in the working chamber 111.
Specifically, the end of washing of the dishwasher 100 means that the dishwasher 100 has finished the washing process, which generally sequentially includes several processes of washing, rinsing, and drying, and the end of washing of the dishwasher 100 generally means that the drying process has finished. Steps S151, S152, and S153 of an embodiment of the present invention may be regarded as a custody procedure, and steps S151, S152, and S153 may be performed in a plurality of cycles to keep the working chamber 111 dry.
Referring to Figure 4, in some embodiments, the control method includes the following steps:

S155: determining whether the temperature is greater than or equal to a second preset temperature, wherein the second preset temperature is greater than the first preset temperature; and
S156: stopping the heating device 130 and the first fan 140 when the temperature is greater than or equal to the second preset temperature.

Referring again to Figure 2, in some embodiments, the processor 150 is configured to:

determining whether the temperature is greater than or equal to a second preset temperature, wherein the second preset temperature is greater than the first preset temperature; and
stopping the heating device 130 and the first fan 140 when the temperature is greater than or equal to the second preset temperature.

That is, steps S155 and S156 may be implemented by processor 150.
In this manner, the energy consumption of the dishwasher 100 can be reduced and damage to the heating device 130 and the first fan 140 can be avoided.
Specifically, when the temperature is relatively high, for example, when the temperature is greater than or equal to the second preset temperature, it is difficult for the water vapor in the working chamber 111 to condense into water droplets, so that the heating device 130 and the first fan 140 can be stopped, thereby reducing the power consumption of the dishwasher 100. On the other hand, it is possible to avoid the problem of damage such as burning, abrasion and the like caused by the fact that the heating device 130 and the first fan 140 are always in operation.
In some embodiments, when the temperature is less than the second preset temperature, the temperature detection unit 120 may be controlled to detect the temperature after a second time interval, i.e., step S151 is re-executed after the second time interval. In addition, the heating device 130 and the first fan 140 can be controlled to keep the original state, that is, to keep operating if the heating device 130 and the first fan 140 were previously in the operating state; and to remain closed if the heating device 130 and the first fan 140 were previously closed.
It should be noted that the first time interval and the second time interval may be the same or different and are not specifically limited herein.
In some embodiments, the second preset temperature is between 45 °C and 50 °C. In this manner, frequent operation and stoppage of the heating device 130 and the first fan 140 can be avoided, and energy consumption of the dishwasher 100 can be reduced.
Specifically, if the value of the second preset temperature is too small, for example, less than 45 °C, the second preset temperature may be closer to the first preset temperature, so that the temperature of the working chamber 111 is easily less than or equal to the first preset temperature after the heating device 130 and the first fan 140 are stopped for a short period of time, that is, the heating device 130 and the first fan 140 are operated again within a short time after being stopped. The heating device 130 and the first fan 140 are frequently operated and stopped, which may cause damage to the heating device 130 and the first fan 140; if the value of the second preset temperature is too large, for example, greater than 50 °C, the operating time of the heating device 130 and the first fan 140 needs to be increased or the operating power of the heating device 130 and the first fan 140 needs to be increased, thereby increasing the power consumption of the dishwasher 100. Therefore, the second preset temperature may be set to 45 °C to 50 °C. In other embodiments, the second preset temperature may also be adjusted according to user requirements, for example, the second preset temperature may also be between 45 °C and 60 °C.
Referring to Figures 5 and 6 together, in some embodiments, the housing 110 is provided with an air duct 112 communicating outside and the working chamber 111, and the dishwasher 100 includes a second fan 160 disposed within the air duct 112; the control method comprises the following steps:
S157: controlling the second fan 160 to operate when the first fan 140 operates.
Referring again to Figure 6, in some embodiments, the housing 110 is provided with an air duct 112 communicating outside (exterior of the dishwasher 100) and the working chamber 111, the dishwasher 100 including a second fan 160 disposed within the duct 112; the processor 150 is configured to control the second fan 160 to operate when the first fan 140 operates.
That is, step S157 may be implemented by processor 150.
In this manner, the first fan 140 and the second fan 160 may cooperate to establish an airflow communicating the outside and the working chamber 111, thereby improving the dehumidification effect.
Specifically, the second fan 160 may be provided in the air duct 112 communicating the outside and the working chamber 111. The airflow with heat formed by the operation of the heating device 130 and the first fan 140 evaporates the water droplets so that the airflow carries the water vapor, and the second fan 160 directs the air flow from the inside of the working chamber 111 to the outside so that the water vapor can be discharged from the working chamber 111 to the outside.
Referring again to Figure 6, in some embodiments, the air duct 112 is disposed at the top of the working chamber 111.
In this way, the airflow with heat formed by the operation of the heating device 130 and the first fan 140 easily flows to the outside.
It will be appreciated that the density of the hot air is small, and the airflow with heat formed by the heating device 130 and the first fan 140 tends to rise, so that the air duct 112 is disposed at the top of the working chamber 111 so that the airflow with heat rises and then flows out of the air duct 112. In addition, the second fan 160 is arranged in the air duct 112 and the air duct 112 is arranged at the top of the working chamber 111, so that the airflow with heat can be conveniently guided to the outside when the second fan 160 works.
In some embodiments, since the space of the working chamber 111 is limited, for example, the working chamber 111 is small, the temperature detection unit 120 cannot be directly installed in the working chamber 111, and therefore, the temperature detection unit 120 can be installed in the air duct 112, and the temperature in the air duct 112 can be detected by the temperature detection unit 120. In some embodiments, the temperature within the air duct 112 may be considered the temperature of the working chamber 111.
In some embodiments, the temperature detection unit 120 may be disposed directly within the working chamber 111 to accurately obtain the temperature of the working chamber 111, and is not specifically limited thereto.
