Description

Technical Field

[0001] The present application relates to the technical field of air conditioners, for example, to a detection method and device for air conditioners, an air conditioner, and a storage medium. Background Art

[0002] At present, with the rapid development of science and technology, the popularity of smart home appliances among consumers is increasing. Air conditioners are favored by consumers because of their good environmental regulation functions such as cooling, heating and dehumidification. When purchasing air conditioners, users usually ask sales staff to demonstrate the relevant functions of the air conditioner on site, such as the fresh air function and dehumidification function. However, the air conditioner prototype and the actual air conditioner are smaller in appearance, and the two have different structures in the indoor unit. Compared with the actual air conditioner, the air conditioner prototype does not have an indoor heat exchanger structure.

[0003] When the air conditioner is a real air conditioner, the salesperson can demonstrate its fresh air function by turning on the fresh air mode. However, before the real air conditioner demonstrates the fresh air function, it is necessary to obtain the outdoor ambient temperature value first. The fresh air mode can only be turned on when the outdoor ambient temperature value meets the fresh air turning-on condition. Since the air conditioner prototype is not equipped with an outdoor unit, it is impossible to obtain the outdoor ambient temperature value. Therefore, the solution for turning on the fresh air function of the real air conditioner is not applicable to the air conditioner prototype.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] How to control the air conditioner prototype to display the fresh air function when the outdoor ambient temperature value cannot be obtained. Summary of the invention

[0006] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0007] The embodiments of the present disclosure provide a detection method, a device, an air conditioner and a storage medium for an air conditioner, so as to provide a method for activating a fresh air function that is applicable to an air conditioner prototype and is not dependent on an outdoor ambient temperature value.

[0008] In some embodiments, the method includes: obtaining the communication connection status between the indoor unit and the outdoor unit; determining the optional type of the indoor unit based on the communication connection status, the optional type being a prototype or a real machine; obtaining indoor temperature information associated with the indoor unit; determining a target type from the optional types based on the indoor temperature information; and when the target type is a prototype, controlling the indoor unit to execute a fresh air mode.

[0009] In some embodiments, the device includes a processor and a memory storing program instructions, and the processor is configured to execute the aforementioned detection method for the air conditioner when running the program instructions.

[0010] In some embodiments, the air conditioner includes the detection device for the air conditioner as described above.

[0011] In some embodiments, the storage medium stores program instructions, and when the program instructions are run, the detection method for the air conditioner as described above is executed.

[0012] The detection method, device, air conditioner and storage medium for an air conditioner provided in the embodiments of the present disclosure can achieve the following technical effects:

[0013] Since neither the prototype nor the actual machine is equipped with an outdoor unit, when the indoor unit and the outdoor unit are disconnected, it can be determined that the air conditioner is not equipped with an outdoor unit, thereby determining that the optional type of the indoor unit is a real machine or a prototype. At the same time, compared with the actual machine, the prototype is not equipped with a hardware circuit for collecting indoor temperature, so the prototype cannot obtain valid indoor temperature information. Therefore, the embodiment of the present disclosure can exclude the actual machine type from the optional types based on the indoor temperature information, and determine that the target type of the indoor unit is the prototype. When determining that the target type is a prototype, the embodiment of the present disclosure can directly control the indoor unit to execute the fresh air mode to demonstrate its fresh air function without relying on the outdoor ambient temperature value.

[0022] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0026] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0027] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0028] With the rapid development of science and technology, the popularity of smart home appliances among consumers is increasing. Air conditioners are favored by consumers because of their good environmental regulation functions such as cooling, heating and dehumidification. When purchasing an air conditioner, users usually ask the salesperson in the store to demonstrate the relevant functions of the air conditioner on site, such as the fresh air function and dehumidification function. However, the air conditioner prototype and the actual air conditioner are smaller in appearance, and there are differences in the structure of the indoor unit between the two. Compared with the actual air conditioner, the air conditioner prototype does not have an indoor heat exchanger structure.

[0029] When the air conditioner is a real air conditioner, the salesperson can demonstrate its fresh air function by turning on the fresh air mode. However, before the real air conditioner demonstrates the fresh air function, it is necessary to obtain the outdoor ambient temperature value first. The fresh air mode can only be turned on when the outdoor ambient temperature value meets the fresh air turning-on condition. Since the air conditioner prototype is not equipped with an outdoor unit, it is impossible to obtain the outdoor ambient temperature value. Therefore, the solution for turning on the fresh air function of the real air conditioner is not applicable to the air conditioner prototype.

[0030] The related technology has the following problem: when the outdoor ambient temperature value cannot be obtained, the air conditioner prototype cannot be controlled to display the fresh air function.

[0031] Figure 1 The hardware structure diagram of the air conditioner is shown in Figure 1. Figure 1 As shown, an embodiment of the present disclosure provides an air conditioner, including an outdoor unit 2 and an indoor unit 1. The outdoor unit 2 is provided with a first control board 21. The indoor unit 1 is provided with a second control board 11 which can be communicatively connected with the first control board 21 and a temperature acquisition circuit 12 for collecting indoor temperature. The temperature acquisition circuit 12 is provided with an indoor temperature sensor (not shown in the figure) and an inner coil temperature sensor (not shown in the figure). The air conditioner can be any of a wall-mounted air conditioner, a cabinet air conditioner or a duct air conditioner.

[0032] The air conditioner prototype represents an air conditioner that is not equipped with an outdoor unit 2 and the indoor unit 1 is not equipped with an indoor heat exchanger and a hardware circuit for collecting indoor temperature. The air conditioner real machine represents an air conditioner that is not equipped with an outdoor unit 2 and the indoor unit 1 is equipped with an indoor heat exchanger and a hardware circuit for collecting indoor temperature. Among them, the hardware circuit for collecting indoor temperature includes a temperature collection circuit 12.

[0033] Based on the above air conditioner, combined with Figure 2 As shown, the embodiment of the present disclosure provides a detection method for an air conditioner, comprising:

[0034] S01, the processor obtains the communication connection status between the indoor unit and the outdoor unit.

[0035] S02: The processor determines, according to the communication connection state, that the optional type of the indoor unit is a prototype unit or a real unit.

[0036] S03: The processor obtains indoor temperature information associated with the indoor unit.

[0037] S04: The processor determines a target type from optional types according to the indoor temperature information.

[0038] S05: When the target type is a prototype, the processor controls the indoor unit to execute a fresh air mode.

[0039] Using the detection method for the air conditioner provided by the embodiment of the present disclosure, since neither the prototype nor the actual machine is equipped with an outdoor unit, when the indoor unit and the outdoor unit are in a disconnected state, it can be determined that the air conditioner is not equipped with an outdoor unit, thereby determining that the optional type of the indoor unit is a real machine or a prototype. At the same time, compared with the actual machine, the prototype is not equipped with a hardware circuit for collecting indoor temperature, and the prototype cannot obtain valid indoor temperature information. Therefore, the embodiment of the present disclosure can exclude the actual machine type from the optional types based on the indoor temperature information, and determine that the target type of the indoor unit is the prototype. When determining that the target type is the prototype, the embodiment of the present disclosure can directly control the indoor unit to execute the fresh air mode to demonstrate its fresh air function without relying on the outdoor ambient temperature value.

[0040] The execution subject of the above detection method for air conditioner is a processor, which can be configured on the air conditioner or on a server connected to the air conditioner.

[0041] Optionally, the processor determines, according to the communication connection state, that the optional type of the indoor unit is a prototype or a real unit, including:

[0042] The processor determines that the optional type of the indoor unit is a prototype unit or a real unit when the communication connection state indicates that the indoor unit is disconnected from the outdoor unit.

[0043] In this way, since neither the prototype nor the actual machine is equipped with an outdoor unit, when the indoor unit and the outdoor unit are disconnected, it can be determined that the air conditioner is not equipped with an outdoor unit, thereby determining that the optional type of the indoor unit is an actual unit or a prototype. Through the indoor and outdoor communication connection status, the optional type of the indoor unit can be more accurately known, improving the accuracy of the indoor unit type judgment. In addition, without relying on the outdoor ambient temperature value, the indoor unit is directly controlled to execute the fresh air mode to demonstrate its fresh air function.

[0044] Optionally, combined Figure 3 As shown, the processor obtains the communication connection status between the indoor unit and the outdoor unit, including:

[0045] S11, the processor controls the second control board to send a connection request to the first control board, so that the second control board receives and generates a connection response when communicating with the first control board.

[0046] S12, the processor determines whether the second control board receives a connection response, if not, executes S13, if yes, executes S14.

[0047] S13, the processor determines that the indoor unit is disconnected from the outdoor unit.

[0048] S14, the processor determines that the indoor unit is connected to the outdoor unit.

[0049] In this way, after the second control board sends a connection request to the first control board, by detecting whether the second control board receives a connection response, it is possible to accurately identify whether the second control board and the first control board are disconnected, thereby improving the reliability of judging the communication connection status of the indoor and outdoor units.

[0050] It is understandable that the connection request can be implemented as a high or low level trigger signal, or as a binary code with a continuous time sequence. The connection response is implemented in the same way as the connection request. This embodiment of the present disclosure does not specifically limit this.

[0051] Optionally, combined Figure 4 As shown, the processor determines the target type from the optional types according to the indoor temperature information, including:

[0052] S21, when the processor does not receive the indoor temperature information at the port configured by the second control board, it is determined that the temperature acquisition circuit is disconnected from the second control board.

[0053] S22: The processor determines the target type of the indoor unit as a prototype from the optional types.

[0054] The port represents the connection port between the temperature sensor and the second control board.

[0055] In this way, since the indoor unit of the prototype is not equipped with an indoor heat exchanger and a hardware circuit for collecting indoor temperature, the indoor temperature information cannot be received when the indoor unit is a prototype. Therefore, by judging whether the port configured by the second control board receives the indoor temperature information, it is possible to determine whether the temperature acquisition circuit is connected to the second control board. And when determining the disconnection, exclude the real machine type and determine the prototype type. The disclosed embodiment can accurately identify the target type of the indoor unit based on whether the second control board configured in the indoor unit receives the indoor temperature information, thereby improving the accuracy of the indoor unit type judgment. Thereby, without relying on the outdoor ambient temperature value, the indoor unit is directly controlled to execute the fresh air mode to demonstrate its fresh air function.

[0056] Optionally, the indoor temperature information includes an indoor temperature value and an internal coil temperature value.

[0057] Determine that the indoor temperature information is not received at the port configured on the second control board as follows:

[0058] The port configured with the second control board does not receive the indoor temperature value collected by the indoor temperature sensor; and,

[0059] The port configured on the second control board does not receive the inner coil temperature value collected by the inner coil temperature sensor.

[0060] In this way, when the second control board does not receive the indoor temperature value collected by the indoor temperature sensor, it indicates that the second control board is disconnected from the indoor temperature sensor. When the second control board does not receive the inner coil temperature value collected by the inner coil temperature sensor, it indicates that the second control board is disconnected from the inner coil temperature sensor. In this way, it can be determined that the indoor unit is not equipped with an indoor temperature sensor and an inner coil temperature sensor. This is more conducive to the reliability of the connection judgment between the temperature acquisition circuit and the second control board, and further improves the accuracy of the indoor unit type judgment.

[0061] It should be noted that the port includes a first port and a second port. The first port represents a connection port between the indoor temperature sensor and the second control board. The second port represents a connection port between the inner coil temperature sensor and the second control board. The second control board can determine the connection status of the indoor temperature sensor according to the reception status of the indoor temperature value at the first port, and can determine the connection status of the inner coil temperature sensor according to the reception status of the inner coil temperature value at the second port.

[0062] Optionally, the processor determines the target type of the indoor unit as a prototype from the optional types:

[0063] The processor controls the indoor fan to run at a preset speed value, and obtains the power value of the indoor fan running at the preset speed.

[0064] The processor determines that the target type of the indoor unit is a prototype unit when the power value matches the target power value.

[0065] The target power value indicates the power value corresponding to the indoor fan configured in the prototype when it runs at a preset speed value.

[0066] In this way, the air conditioner prototype is not equipped with an indoor heat exchanger, and the difference in performance between it and the actual air conditioner includes: the operating power of the indoor fan of the air conditioner prototype and the actual air conditioner when powered on is different. Specifically, when other conditions are controlled to be the same, the operating power value of the indoor fan of the actual air conditioner is less than the operating power value of the indoor fan of the air conditioner prototype. Based on the above difference, the embodiment of the present disclosure pre-stores the power value of the indoor fan of the prototype at a preset speed. When the power value running at the preset speed matches the target power value, the indoor unit can be accurately determined to be a prototype, further improving the accuracy of indoor unit type judgment.

[0067] Optionally, the power value matches the target power value, including the power value being equal to the target power value, or the power value being within a preset range corresponding to the target power value. The preset range is [target power value - power deviation, target power value + power deviation]. The power deviation is approximately 5% of the target power value.

[0068] Optionally, combined Figure 5As shown, the processor obtains the communication connection status between the indoor unit and the outdoor unit, including:

[0069] S31, the processor controls the air conditioner to operate in a cooling mode.

[0070] S32: The processor obtains the internal coil temperature information associated with the indoor unit.

[0071] S33: The processor determines that the indoor unit is disconnected from the outdoor unit when the temperature information of the inner coil remains unchanged.

[0072] In this way, since the prototype is not equipped with an outdoor unit, when the prototype is running in cooling mode, the indoor unit cannot form a refrigeration cycle with the outdoor unit, so the temperature information of the inner coil associated with the indoor unit must be maintained continuously. Therefore, the embodiment of the present disclosure can determine the connection status of the indoor and outdoor units based on whether the temperature of the inner coil remains unchanged. In this way, the optional type of the indoor unit can be known more accurately, and the accuracy of indoor unit type determination is improved.

[0073] The inner coil temperature information remains unchanged, including: the inner coil temperature value is maintained continuously within a preset time period.

[0074] In practical applications, the detection method for air conditioners specifically performs the following steps:

[0075] S41, after the processor configured in the air conditioner determines that the air conditioner is powered on, it controls the second control board to send a connection request to the first control board. After judging, the second control board does not receive a connection response, and determines that the indoor unit is disconnected from the outdoor unit. Thus, it is known that the air conditioner is one of the optional types of prototype or real machine.

[0076] S42, the processor determines whether the port configured by the second control board receives the indoor temperature information. After judging, the port of the second control board does not receive the indoor temperature information, and determines that the temperature acquisition circuit is disconnected from the second control board. Therefore, it is known that the target type of the air conditioner is a prototype.

[0077] S43, the processor controls the indoor unit to directly turn on the fresh air mode and operate in the fresh air mode.
