[0002] Air conditioners are common electrical appliances used in shopping malls, homes, and offices, used to regulate indoor temperature, air, and humidity. As people become more health-conscious, their demands for air conditioner functions are also increasing. For example, during long-term operation, bacteria can accumulate on the indoor heat exchanger, affecting the indoor environment; therefore, air conditioners also need a sterilization function.

[0003] In existing technologies, the sterilization method for air conditioners involves controlling the air conditioner to be in heating mode and stopping the indoor fan to increase the temperature of the indoor evaporator, thereby achieving a sterilization effect. However, heating the indoor evaporator solely through the air conditioner's heating function during the sterilization process results in a slow heating rate, or even prevents the indoor evaporator from reaching the temperature required for sterilization, leading to poor sterilization results.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0045] Please see Figure 1 , Figure 1 The diagram shown is a suitable structural diagram of the piping of an air conditioner provided in this application. The air conditioner includes a compressor 1, an indoor heat exchanger 11, an indoor fan 12, an outdoor heat exchanger 21, an outdoor fan 22, a pipe valve 4, a four-way valve 5, and an auxiliary heating device. The compressor 1, the indoor heat exchanger 11, the outdoor heat exchanger 21, and the pipe valve 4 are connected to form an air conditioner piping circuit. The auxiliary heating device includes a first heat pipe 31 and a second heat pipe 32. The first end of the first heat pipe 31 is located at the compressor 1, for example, coiled at the position where the first heat pipe 31 generates heat during operation. The second end is thermally connected to the indoor heat exchanger 11, for example, wrapped around the pipe at the inlet of the indoor heat exchanger 11. A first valve 33 is provided on the first heat pipe 31. When the first valve 33 is open, the first heat pipe 31 can transfer the heat generated by the compressor 1 during operation to the indoor heat exchanger 11. The first end of the second heat pipe 32 is located at the outdoor fan 22, for example, coiled at the position where the outdoor fan 22 generates heat during operation. The second end is thermally connected to the indoor heat exchanger compressor 1, for example, wrapped around the pipe at the outlet of the indoor heat exchanger 11, and a second valve 34 is provided on the second heat pipe 32. When the second valve 34 is open, the second heat pipe 32 can transfer the heat generated by the outdoor fan 22 to the indoor heat exchanger 11. In this embodiment, the first valve 33 and the second valve 34 can be solenoid valves, and the controller of the air conditioner is connected to the first valve 33 and the second valve 34, and can control the opening and closing of the first valve 33 and the second valve 34.

[0046] Figure 1 The sterilization control method of the air conditioner shown is as follows: Figure 2 As shown, it includes the following steps:

[0047] Step S1: Upon receiving the sterilization signal, control the air conditioner to switch to heating mode.

[0048] In step S1 above, the sterilization signal can be a line signal input by the user through the air conditioner control panel, a remote control signal sent by the user through the remote control, or a control signal sent by the user's smart terminal to the controller after establishing a communication connection between the user's smart terminal and the air conditioner. After receiving the line signal, remote control signal, or control signal, the air conditioner identifies it to determine whether it is a sterilization signal. If it is, the air conditioner switches to heating mode to raise the temperature of the indoor evaporator in order to provide high-temperature air for sterilization.

[0049] Step S2: Obtain the temperature value of the indoor heat exchanger 11, and control the compressor 1, the first valve 33 and the second valve 34 according to the temperature value of the indoor heat exchanger 11 to carry out sterilization treatment.

[0050] In step S2 above, a temperature sensor can be installed at the indoor heat exchanger 11. The temperature sensor can detect the temperature value of the indoor heat exchanger 11. When obtaining the temperature value of the indoor heat exchanger 11, the temperature value of the indoor heat exchanger 11 can be obtained by receiving the detection data of the temperature sensor. Both the compressor 1 and the auxiliary heating device can control the temperature of the indoor heat exchanger 21. For example, the temperature of the indoor heat exchanger 21 can be increased by increasing the frequency of the compressor 1. By controlling the opening of the first valve 33 and the second valve 34, the heat generated by the outdoor fan 22 and the compressor 1 during operation can be transferred to the indoor heat exchanger 21, respectively. Since the indoor heat exchanger 21 needs to be in a high-temperature state during sterilization, in this embodiment, the temperature of the indoor heat exchanger 21 is controlled by the compressor 1 and the auxiliary heating device to ensure that the temperature value of the indoor heat exchanger 21 meets the sterilization requirements, thereby achieving the sterilization effect.

[0051] In summary, in the technical solution of this application, the first end of the first heat pipe 31 of the auxiliary heating device is located at the compressor 1, and the second end is thermally connected to the indoor heat exchanger 21, which can conduct the heat generated by the compressor 1 during operation to the indoor heat exchanger 21; the first end of the second heat pipe 32 is located at the outdoor fan 22, and the second end is thermally connected to the indoor heat exchanger 21, which can conduct the heat generated by the outdoor fan 22 during operation to the indoor heat exchanger 21. When the air conditioner is performing sterilization, the auxiliary heating device can transfer the heat generated by the compressor 1 and the outdoor fan 22 during operation to the indoor heat exchanger 21, thereby improving the heating efficiency of the indoor heat exchanger 21 and ensuring that the temperature of the indoor heat exchanger 21 reaches the temperature required for sterilization, thus improving the sterilization effect. Furthermore, in this embodiment, the heat generated by the compressor 1 and the outdoor fan 22 during operation is used to heat the indoor heat exchanger 21, eliminating the need for separate heating energy and reducing the cost of air conditioner sterilization.

[0052] In one embodiment, during the sterilization process, the indoor fan 12 is also controlled to operate at a speed not exceeding a set speed, meaning the indoor fan 12 runs continuously. This allows the heat from the indoor heat exchanger 21 to be blown into the room, raising the indoor temperature and thus sterilizing the room. Because the speed of the indoor fan 12 does not exceed the set speed, the airflow velocity at the indoor heat exchanger 21 will not be too high, and the temperature of the indoor heat exchanger 21 will not drop too low due to the action of the indoor fan 12. Therefore, this embodiment's setup can sterilize not only the surface of the indoor heat exchanger but also the entire room, thus improving the sterilization effect.

[0053] In one embodiment, step S2 above involves obtaining the temperature values ​​of the indoor heat exchanger 21, including the inlet temperature, coil temperature, and outlet temperature of the indoor heat exchanger 21. In this embodiment, a first temperature sensor, a second temperature sensor, and a third temperature sensor can be installed at the inlet, coil, and outlet of the indoor heat exchanger 21, respectively, to detect the inlet temperature, coil temperature, and outlet temperature of the indoor heat exchanger 21. When it is necessary to obtain the inlet temperature, coil temperature, and outlet temperature values ​​of the indoor heat exchanger 21, the detection data from the first temperature sensor, the second temperature sensor, and the third temperature sensor can be received.

[0054] In this embodiment, the process of controlling the compressor 1, the first valve 33, and the second valve 34 based on the temperature value of the indoor heat exchanger 21 is as follows: Figure 3 As shown, it includes:

[0055] Step S201: Obtain the sterilization temperature value.

[0056] In this embodiment, the sterilization temperature value can be a preset temperature value or a temperature value input by the user to the air conditioner via a remote control or air conditioner control panel. When the sterilization temperature value is a preset temperature value, it can be stored in the air conditioner. When the sterilization temperature value is needed, it can be directly read and used as the sterilization temperature value. When the sterilization temperature value is a temperature value input by the user, the temperature value input by the user can be received first and then used as the sterilization temperature value.

[0057] Step S202: Based on the relationship between the inlet temperature, outlet temperature, and coil temperature of the indoor heat exchanger 21 and the sterilization temperature, control the frequency of the compressor 1 and the opening and closing of the first valve 33 and the second valve 34 to ensure that the temperature of the indoor heat exchanger 21 meets the preset conditions.

[0058] In this embodiment, the sterilization temperature value can be used as a threshold. When the inlet temperature value, outlet temperature value, or coil temperature value of the indoor heat exchanger 21 is lower than the sterilization temperature value, it can be considered that the temperature of the indoor heat exchanger 21 is too low, affecting the sterilization effect. At this time, the frequency of the compressor 1 can be controlled to increase the temperature of the indoor heat exchanger 21, or the first valve 33 and / or the second valve 34 can be controlled to open so that the heat generated by the compressor 1 and / or the outdoor fan 22 when it is working can be transferred to the indoor heat exchanger 21 to heat the indoor heat exchanger 21, so that the inlet temperature value, outlet temperature value, and coil temperature value of the indoor heat exchanger 21 are not lower than the sterilization temperature value, thereby improving the sterilization effect.

[0059] The configuration of this embodiment allows for multi-point detection of the indoor heat exchanger 21, ensuring that the temperature at each point on the indoor heat exchanger 21 is not lower than a preset temperature value, thereby improving the sterilization effect. The following, using an embodiment, details a method for controlling the frequency of the compressor 1 and the opening and closing of the first valve 33 and the second valve 34 based on the relationship between the inlet temperature, outlet temperature, and coil temperature of the indoor heat exchanger 21 and the sterilization temperature value. It should be understood that the implementation methods in the following embodiment are exemplary and not restrictive.

[0060] In one embodiment, the second end of the first heat pipe 31 is thermally connected to the inlet of the indoor heat exchanger 21, and the first heat pipe 31 can transfer the heat generated when the compressor 1 is working to the inlet of the indoor heat exchanger 21 to increase the temperature of the inlet of the indoor heat exchanger 21; the second end of the second heat pipe 32 is thermally connected to the outlet of the indoor heat exchanger 21, and the second heat pipe 32 can transfer the heat generated when the outdoor fan 22 is working to the outlet of the indoor heat exchanger 21 to increase the temperature of the outlet of the indoor heat exchanger 21.

[0061] In this embodiment, the frequency of the compressor 1 and the opening and closing process of the first valve 33 and the second valve 34 are controlled according to the relationship between the inlet temperature, outlet temperature, and coil temperature of the indoor heat exchanger 21 and the sterilization temperature, as follows: Figure 4 As shown, it includes the following steps:

[0062] Step S211: When the inlet temperature, outlet temperature, and coil temperature of the indoor heat exchanger 21 are all lower than the sterilization temperature, control the first valve 33 and the second valve 34 to open, and increase the frequency of the compressor 1 to the first frequency. Since the inlet temperature, outlet temperature, and coil temperature of the indoor heat exchanger 21 are all lower than the sterilization temperature, it can be considered that the inlet, outlet, and coil temperatures of the indoor heat exchanger 21 are all too low. At this time, controlling the opening of the first valve 33 and the second valve 34 and increasing the frequency of the compressor 1 to the first frequency can not only raise the temperature of the indoor heat exchanger 21 through the action of the compressor 1, but also transfer the heat generated by the compressor 1 and the heat generated by the outdoor fan 22 to the indoor heat exchanger 21, thereby improving the heating efficiency of the indoor heat exchanger 21.

[0063] Step S212: When the inlet and outlet temperatures of the indoor heat exchanger 21 are lower than the sterilization temperature, and the coil temperature is not lower than the sterilization temperature, the first valve 33 and the second valve 34 are opened, and the compressor 1 is increased to a second frequency, wherein the second frequency is lower than the first frequency. When the inlet and outlet temperatures of the indoor heat exchanger 21 are lower than the sterilization temperature, but the coil temperature is not lower than the sterilization temperature, it can be considered that the inlet and outlet temperatures of the indoor heat exchanger 21 are too low. At this time, opening the first valve 33 and the second valve 34 can transfer the heat generated by the compressor 1 during operation to the inlet of the indoor heat exchanger 21 and the heat generated by the outdoor fan 22 during operation to the outlet of the indoor heat exchanger 21, thereby heating the inlet and outlet temperatures of the indoor heat exchanger 21. This not only improves the heating efficiency of the indoor heat exchanger 21, but also reduces the energy consumption of the compressor 1 by controlling the compressor 1 to increase to a second frequency lower than the first frequency.

[0064] Step S213: When the inlet temperature of the indoor heat exchanger 21 is lower than the sterilization temperature and the outlet temperature is not lower than the sterilization temperature, the first valve 33 is opened and the compressor 1 is increased to the third frequency, wherein the third frequency is lower than the second frequency. When the inlet temperature of the indoor heat exchanger 21 is lower than the sterilization temperature and the outlet temperature is not lower than the sterilization temperature, it can be considered that only the inlet temperature of the indoor heat exchanger 21 is low. At this time, opening the first valve 33 can transfer the heat generated by the frequency converter to the inlet of the indoor heat exchanger 21 to heat the inlet of the indoor heat exchanger 21, thereby improving the heating efficiency of the indoor heater inlet. In addition, since the third frequency is lower than the second frequency, the energy consumption of the compressor 1 can be reduced.

[0065] Step S214: When the inlet temperature of the indoor heat exchanger 21 is not less than the sterilization temperature and the outlet temperature is less than the sterilization temperature, control the second valve 34 to open and the compressor 1 to increase the frequency to the third frequency. When the inlet temperature of the indoor heat exchanger 21 is not less than the sterilization temperature and the outlet temperature is less than the sterilization temperature, it can be considered that only the inlet temperature of the indoor heat exchanger 21 is low. At this time, controlling the second valve 34 to open can transfer the heat generated by the frequency converter to the outlet of the indoor heat exchanger 21 to heat the outlet of the indoor heat exchanger 21, thereby improving the heating efficiency of the indoor heater outlet. In addition, the third frequency is less than the second frequency mentioned above, which can reduce the energy consumption of the compressor 1.

[0066] The configuration of this embodiment can control the frequency of compressor 1 and the opening and closing of the first valve 33 and the second valve 34 based on the inlet temperature, outlet temperature and coil temperature of indoor heat exchanger 21, and based on the relationship between the inlet temperature, outlet temperature and coil temperature and sterilization temperature. This not only reduces the energy consumption of compressor 1 during sterilization, but also improves the adjustment efficiency of the inlet temperature, outlet temperature and coil temperature of indoor heat exchanger 21.

[0067] In one embodiment, the process of obtaining the sterilization temperature value in step S211 above is as follows: Figure 5 As shown, it includes the following steps:

[0068] Step S221: Determine whether a user-inputted temperature value has been received within a preset time period. This user-inputted temperature value can be entered by the user via the air conditioner's remote control, the air conditioner's control panel, or by establishing a communication connection between a smartphone or other smart terminal and the air conditioner, sending the temperature value to the air conditioner via the smart terminal. The preset time period is the set time period after receiving the sterilization signal, for example, 1 minute after receiving the sterilization signal. If a user-inputted temperature value is received within this time period, it is assumed that the user wishes to use this temperature value as the sterilization temperature.

[0069] Step S222: If received, the temperature value input by the user is used as the sterilization temperature value;

[0070] If no temperature is received, a preset temperature value is obtained and used as the sterilization temperature value. For example, the preset temperature value stored on the air conditioner can be obtained by data reading and used as the sterilization temperature value.

[0071] In this embodiment, the preset temperature value is 56℃. Since most bacteria can be killed at 56℃, resulting in a good sterilization effect, the sterilization effect is poor below 56℃. Therefore, in this embodiment, the preset temperature value is set to 56℃ to ensure the sterilization effect during the air conditioner's sterilization process.

[0072] By using the setting method in this embodiment, the priority of the temperature value input by the user can be increased when obtaining the sterilization temperature value, and the temperature value input by the user can be used as the sterilization temperature value to meet the user's requirements for sterilization treatment.

[0073] In one embodiment, the sterilization control method for the air conditioner of this application further includes the following steps:

[0074] During the sterilization process, it is determined whether a signal to stop the sterilization process has been received, or whether the sterilization process has reached the set duration.

[0075] If a signal to stop the sterilization process is received, or if the sterilization process has reached the set duration, the sterilization process will be stopped.

[0076] In this embodiment, the signal to stop sterilization can be a line signal input by the user through the air conditioner control panel, a remote control signal sent by the user through the remote control, or a control signal sent by the user's smart terminal to the controller after establishing a communication connection between the user's smart terminal and the air conditioner. Upon receiving the line signal, remote control signal, or control signal, the air conditioner identifies it and determines whether it is a signal to stop sterilization. If so, it assumes the user intends to stop sterilization and stops the process. If no signal to stop sterilization is received, but the sterilization duration has reached the set time, it is considered that the sterilization effect has achieved the expected result, and the sterilization process also stops.

[0077] In this embodiment, stopping the sterilization process can be achieved by controlling the first valve 33 and the second valve 34 to close, controlling the compressor 1 to stop, controlling the indoor fan 12 to stop, or controlling the air conditioner to be in standby mode, or controlling the air conditioner to be turned off.
