[0032] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0033] In the description of the embodiments of the present invention, the terms “first” and “second” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0034] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on the specific circumstances.

[0035] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiment of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0036] When the air conditioner is running, the indoor unit often makes a "crackling" sound. This is due to the large temperature difference between the indoor unit and the indoor air, which causes the plastic components of the unit to expand and contract due to heat and cold, causing friction and noise. Specifically, during the heating process, due to the rapid rise in ambient temperature, some parts of the indoor unit or their local thermal conductivity are slow to heat up. This creates a large temperature difference between the components and the ambient temperature, causing friction between the components and the noise.

[0037] Currently, the commonly used method is to stick sponge or velvet on the contact surface of the parts assembly to solve the problem, but the production efficiency is low and the effect is not obvious.

[0038] In order to solve the above problems, Figure 1 As shown, the noise reduction control method of the air conditioner according to the embodiment of the present invention includes:

[0039] S100: determining a critical temperature of the structural component according to the ambient temperature of the structural component.

[0040] Based on the material properties of the structural components, simulation experiments were conducted to determine the critical temperatures of the components at different ambient temperatures. The critical temperature refers to the temperature difference at which noise is generated. A database was then established that correlated ambient temperatures with the critical temperatures of the structural components. In other words, once the ambient temperature was known, the critical temperature could be determined by looking up the table.

[0041] It should be noted that the database corresponding to the ambient temperature and the critical temperature of the structural component can be stored in the memory for easy retrieval and storage.

[0042] S200 , controlling the air conditioner to perform corresponding operations according to the actual temperature and critical temperature of the structural component to reduce the noise of the air conditioner.

[0043] The actual temperature is compared with the critical temperature to obtain a comparison result. If the actual temperature is greater than the critical temperature, it means that the structural parts will not rub against each other. If the actual temperature is less than the critical temperature, the air conditioner is controlled to perform corresponding operations to reduce the noise of the air conditioner.

[0044] It should be particularly noted that the structural member may be made of plastic, for example, the structural member may be an air conditioning panel or an air guide plate.

[0045] In this embodiment of the present invention, the critical temperature of the structural component is determined based on the ambient temperature of the structural component. If the actual temperature of the structural component is lower than the critical temperature, the air conditioner is controlled to perform corresponding operations to reduce air conditioner noise. Compared with the existing method of applying sponge or flannel to the contact surface, the noise reduction method of this embodiment is simple and highly effective.

[0046] In an optional embodiment, the method further includes determining a first target temperature and a second target temperature according to the critical temperature, wherein the first target temperature is greater than the second target temperature.

[0047] For example, the critical temperature is 22°C, the first target temperature is 30°C, and the second target temperature is 27°C.

[0048] According to the actual temperature and critical temperature of the structural parts, the air conditioner is controlled to perform corresponding operations to reduce the noise of the air conditioner, including:

[0049] When the actual temperature is less than or equal to the first target temperature and greater than the second target temperature, the structural component is heated.

[0050] For example, when the actual temperature of the structural component is 28° C., the structural component needs to be heated, that is, the temperature of the structural component needs to be raised to above 30° C.

[0051] When the actual temperature is less than or equal to the second target temperature, the fan speed of the indoor unit is reduced and / or the frequency of the compressor is reduced.

[0052] For example, when the actual temperature of the structural component is 23° C., it is necessary to reduce the fan speed of the indoor unit or reduce the frequency of the compressor.

[0053] Alternatively, when the actual temperature of the structural component is 15° C., it is necessary to reduce the fan speed of the indoor unit and the frequency of the compressor.

[0054] In an optional embodiment, determining the first target temperature and the second target temperature according to the critical temperature includes:

[0055] The first target temperature is equal to the sum of the critical temperature and the first correction temperature, and the second target temperature is equal to the sum of the critical temperature and the second correction temperature.

[0056] For example, if the critical temperature is 22° C., the first target temperature is 30° C. and the second target temperature is 27° C. That is, the first correction temperature is 8° C. and the second correction temperature is 5° C.

[0057] It should be noted that the first correction temperature and the second correction temperature are selected according to the material characteristic parameters of the structural component and are not specifically limited here.

[0058] In an optional embodiment, a plurality of heating components are evenly arranged in the structural member, so that the structural member can be evenly heated.

[0059] The heating component may be an electric heating wire. On the premise of ensuring that the heat of the electric heating wire is transferred to the structural component, it is necessary to ensure that the heating process of the electric heating wire does not damage the structure of the structural component.

[0060] It is understandable that the heating component can have its own power supply or share a power supply with the air conditioner indoor unit. The energy supply method of the heating component can be selected according to the actual working conditions and is not specifically limited here.

[0061] It is particularly important to point out that multiple electric heating wires are provided inside the structural member, and a corresponding number of them are arranged based on the shape characteristics of the structural member, and the heating rate of the structural member is controlled by controlling the number of electric heating wires turned on.

[0062] When the actual temperature is less than or equal to the first target temperature and greater than the second target temperature, heating the structural component includes:

[0063] When the actual temperature is less than or equal to the first target temperature and greater than the second target temperature, at least one of the plurality of heating components is turned on.

[0064] For example, if the critical temperature is 22°C, the first target temperature is 30°C and the second target temperature is 27°C. Two electric heating wires are set inside the structural component. When the actual temperature of the structural component is 28°C, one electric heating wire is turned on to heat the structural component. When the actual temperature of the structural component is 27°C, both electric heating wires are turned on to heat the structural component.

[0065] For example, if the critical temperature is 22°C, the first target temperature is 30°C, and the second target temperature is 27°C. An electric heating wire is set inside the structural component. When the actual temperature of the structural component is 28°C, the electric heating wire is turned on to heat the structural component at a first heating power. When the actual temperature of the structural component is 27°C, the electric heating wire is turned on to heat the structural component at a second heating power. The first heating power is lower than the second heating power.

[0066] It is particularly important to note that the heating element can be an electric heating plate, which heats the air conditioner panel by supplying power to the electric heating plate. The electric heating plate is easy to install on the air conditioner panel. The heating element can adjust its heating power. When the heating power is high, the heating intensity of the air conditioner panel is greater. Similarly, when the heating power is low, the heating intensity of the air conditioner panel is less.

[0067] It should be noted that the air conditioner includes an air conditioner panel, which is equipped with an air outlet grille. A temperature sensor and an electric heating plate are located near the air outlet grille on the air conditioner panel. The temperature sensor is configured to detect the temperature of the air conditioner panel, and the electric heating plate is configured to heat the air conditioner panel. The electric heating plate is located on the inner side of the air conditioner panel. It can also be used to heat the air conditioner panel without affecting its appearance.

[0068] In an optional embodiment, the actual temperature of the structural component is obtained as follows:

[0069] Obtain multiple temperatures corresponding to multiple temperature measurement points on the structural part;

[0070] The multiple temperatures are averaged to determine the actual temperature of the structure.

[0071] It should be noted that in order to ensure the accuracy of the actual temperature of the structural component, multiple temperature measuring points can be arranged on the structural component. The number of temperature measuring points is determined by the shape and size of the structural component and is not specifically limited here.

[0072] For example, four temperature measuring points are set on the structural component, and the temperatures of the four temperature measuring points are 25°C, 26°C, 25°C and 27°C respectively. At this time, the actual temperature of the structural component is 25.75°C.

[0073] In an optional embodiment, the multiple temperature measurement points are all located on the surface of the structural component.

[0074] That is, in order to facilitate the measurement of the temperature of the structural member, multiple temperature measurement points are set on the surface of the structural member.

[0075] It should be noted that the surface temperature of the structural component can be obtained by infrared thermal imaging technology, and the ambient temperature can also be obtained by infrared thermal imaging technology. The ambient temperature can also be obtained by a temperature sensor, and the specific acquisition method is not specifically limited here.

[0077] like Figure 2 As shown, the noise reduction control system of the air conditioner according to the embodiment of the present invention includes: a determination module 10 and an execution module 20.

[0078] The determination module 10 is used to determine the critical temperature of the structural component according to the ambient temperature of the structural component.

[0079] The execution module 20 is used to control the air conditioner to perform corresponding operations according to the actual temperature and critical temperature of the structural component to reduce the noise of the air conditioner.

[0080] The determination module 10 is further configured to determine a first target temperature and a second target temperature according to the critical temperature, wherein the first target temperature is greater than the second target temperature.

[0081] Among them, the execution module 20 is also used to heat the structural parts when the actual temperature is less than or equal to the first target temperature and greater than the second target temperature; reduce the fan speed of the indoor unit when the actual temperature is less than or equal to the second target temperature; or reduce the frequency of the compressor; or reduce the fan speed of the indoor unit and reduce the frequency of the compressor.

[0082] The determining module 10 is further configured to determine that the first target temperature is equal to the sum of the critical temperature and the first correction temperature, and the second target temperature is equal to the sum of the critical temperature and the second correction temperature.
