[0002] The square cabinet drives the centrifugal fan blades to operate through the rotation of the motor, and under the action of the volute, the generated wind blows from the bottom of the air conditioner to the head, and finally blows out from the air outlet. In the square cabinet, the volute is arranged under the cabinet, and it is usually made of foam material, so it has a good thermal insulation effect and does not produce condensation water. However, the air outlet at the top is an injection molded part, which has a poor thermal insulation effect. At the same time, since there is an evaporator component under the air outlet, the air outlet temperature is relatively low in the cooling mode, which causes condensation water to easily appear on the inside of the air outlet, thereby affecting the user experience. Therefore, how to avoid condensation water from appearing at the air outlet in the square cabinet is a problem that technicians in this field need to solve. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0038] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0039] See below Figures 1 to 4 The embodiment of the present invention provides an air conditioner, comprising a cabinet body 1, wherein the cabinet body 1 comprises a control mainboard and an air outlet 111, and the air conditioner further comprises:

[0040] A wind shielding mechanism 2 is installed below the air outlet 111;

[0041] The wind shielding mechanism 2 includes a heating unit 21 , which is connected to the control mainboard and is used to heat and increase the temperature of the wind shielding mechanism 2 according to the instruction of the control mainboard.

[0042] The air conditioner described in this embodiment is provided with a wind shielding mechanism 2 below the air outlet 111 (formed by a plurality of air outlet panels 11), and the wind shielding mechanism 2 also includes a heating unit 21 connected to the control mainboard. In this embodiment, the wind shielding mechanism 2 is provided below the air outlet 111 of the cabinet body 1 to block the wind blowing up from the bottom volute 12 so that it cannot blow to other parts of the air outlet panel 11. At the same time, the heating unit 21 is provided on the wind shielding mechanism 2, which can perform corresponding heating actions according to the instructions of the control mainboard, so that the wind shielding mechanism 2 can have a higher temperature. In this way, even if the temperature of the air outlet 111 is low, under the action of the wind shielding mechanism 2, condensation water can be effectively prevented from being generated at the air outlet 111, thereby improving the user experience.

[0043] In a specific embodiment, in combination Figure 2 The cabinet body 1 also includes a volute 12 arranged below the air outlet 111, and the wind shielding mechanism 2 includes a wind shield covering the area between the volute 12 and the area below the air outlet 111, and the two sides of the wind shield are respectively fixedly installed on the two sides of the cabinet body 1.

[0044] This embodiment uses a windshield as the wind shield mechanism 2. The windshield mainly blocks the wind from the bottom of the air outlet 111 to the volute 12. Therefore, the windshield can be installed between the evaporator and the air outlet panel 11. Furthermore, the width of the windshield is flush with the left and right side panels of the cabinet body 1, and the windshield can be installed so that it does not exceed the edge of the side panel on both sides to avoid exposure and affecting the appearance. In addition, the length of the windshield can be determined according to the length from the volute 12 to the air outlet 111, as long as the windshield can cover the area from the volute 12 to the lower end of the air outlet 111. In actual application scenarios, a plurality of mounting positions 24 are respectively provided on the left and right sides of the windshield, and the windshield is fixed to the left and right side panels of the cabinet body 1 through the mounting positions 24. For example, multiple screw holes can be evenly opened as the installation position 24, and the wind shield can be fixed to the left and right side panels of the cabinet body 1 with screws. This can improve the overall sealing of the air conditioner and avoid air leakage due to a large gap between the wind shield and the cabinet body 1, thereby avoiding energy loss.

[0045] Of course, in other application scenarios, other fixing methods can also be used to fix the wind shield to the left and right side panels of the cabinet body 1, such as directly gluing the left and right sides of the wind shield to the left and right side panels of the cabinet body 1, or for example, setting multiple slots on the left and right side panels of the cabinet body 1, and correspondingly setting multiple buckles on the left and right sides of the wind shield, so that when installing and fixing, the buckles are matched with the slots to achieve snap-on connection.

[0046] In one embodiment, in combination Figure 4 The heating part 21 is arranged at any one or more of the top area, the middle area and the bottom area of ​​the wind shield.

[0047] By arranging the heating parts 21 in different areas of the wind shield mechanism 2, the wind shield mechanism 2 can maintain a uniform and constant temperature for a long time, thereby avoiding the problem of condensation water generated due to low temperature in a certain part of the wind shield mechanism 2.

[0048] Specifically, the heating part 21 may be an electric heating plate connected to the control unit. Of course, other heating devices may also be used as the heating part 21 , such as heating wires, that is, heating wires are arranged at different positions of the wind shield mechanism 2 .

[0049] In one embodiment, the air conditioner further comprises a temperature detection module connected to the control main board, and the temperature detection module is used to detect the temperature of the wind shielding mechanism 2 .

[0050] In this embodiment, the temperature of the windshield mechanism 2 is detected by the temperature detection module, and the detected temperature is sent to the control unit. After receiving the temperature of the windshield mechanism 2, the control unit can compare it with a preset temperature threshold, thereby determining whether to heat the windshield mechanism 2 and to what extent according to the comparison result. In addition, the temperature of the air outlet 111 can also be detected by the temperature detection module, and judgment can be made in combination with the temperature of the air outlet 111.

[0051] Specifically, when the air conditioner is running, the temperature of the air outlet 111 of the air conditioner is first detected, and the temperature of the air outlet 111 is compared with a preset temperature threshold; if the temperature of the air outlet 111 is lower than the preset temperature threshold, the temperature of the wind shielding mechanism 2 is continuously detected. Then, the temperature of the wind shielding mechanism 2 is compared with a preset temperature threshold (the preset temperature threshold here can be the same as or different from the temperature threshold corresponding to the previous air outlet 111 temperature); if the temperature of the wind shielding mechanism 2 is lower than the preset temperature threshold, the temperature difference between the temperature of the wind shielding mechanism 2 and the preset temperature threshold is obtained; then, according to the temperature difference, the heating unit 21 is controlled to heat the wind shielding mechanism 2.

[0052] Furthermore, when the temperature detection module detects that the temperature of the wind shield mechanism 2 has reached a preset temperature threshold and has been maintained for a certain period of time, the control unit can control the heating part 21 to cut off power to stop heating. This not only solves the problem of condensation water generated at the air outlet 111, but also avoids waste of resources.

[0053] In a specific embodiment, in combination Figure 4 and Figure 5 A yielding portion 22 is provided in the middle area of ​​the wind shield.

[0054] For the middle area of ​​the windshield, a yielding arrangement can be made according to the structure of the air outlet panel 11 contacting the windshield. In addition, since there is usually no interference with the evaporator located below the cabinet body 1 and the evaporator is far from the installation position of the windshield, the bottom area of ​​the windshield does not need to be yielded.

[0055] Furthermore, at least one rib strip 23 is provided at the upper end and / or the lower end of the wind shield.

[0056] For the upper and lower ends of the windshield, in order to avoid deformation that may lead to poor sealing, ribs 23 are appropriately added to the upper and lower ends of the windshield. This not only avoids air leakage, but also improves the edge structural strength of the windshield.

[0057] Preferably, a downward folded edge is provided at the upper end of the wind shield.

[0058] The upper end of the windshield is designed to be a downward folded edge, which can prevent the edge of the windshield from being too sharp and causing harm to the user, thereby improving the safety performance of the product.

[0059] In some optional embodiments, the wind shield is made of corrosion-resistant material.

[0060] Since the windshield mainly serves to block the wind, its thickness can meet the requirement of not being easily deformed after assembly. However, for example, when the air conditioner is turned on in cooling mode, the windshield will be in a wet and cold environment for a long time, so it is necessary to use a material with strong corrosion resistance to prepare the windshield, such as PA material (PA material is the abbreviation of polyamide material, also known as nylon) to prepare the windshield. Furthermore, an integrated molding mold can be used for preparation to obtain an integrated corrosion-resistant windshield.

[0061] like Figure 6 As shown, an embodiment of the present invention further provides an air conditioner control method, which is applied to the air conditioner as described in any one of the above items, and the method includes: steps S101 to S104.

[0062] Step S101, when the air conditioner is running, detecting the temperature of the wind shielding mechanism 2;

[0063] Step S102, comparing the temperature of the wind shielding mechanism 2 with a preset first temperature threshold;

[0064] Step S103: if the temperature of the wind shielding mechanism 2 is lower than a preset first temperature threshold, obtaining a temperature difference between the temperature of the wind shielding mechanism 2 and the preset first temperature threshold;

[0065] Step S104 , controlling the heating unit 21 to heat the wind shielding mechanism 2 according to the temperature difference.

[0066] In this embodiment, when the air conditioner is running, the temperature of the wind shield mechanism 2 can be detected by the temperature detection module, and the temperature of the wind shield mechanism 2 can be compared with a preset temperature threshold to determine whether the temperature of the wind shield mechanism 2 reaches the preset temperature threshold. If the temperature of the wind shield mechanism 2 does not reach (i.e., is lower than) the preset temperature threshold, the heating unit 21 is controlled to perform a heating and temperature raising action according to the temperature difference between the temperature of the wind shield mechanism 2 and the preset temperature threshold to increase the temperature of the wind shield mechanism 2.

[0067] Furthermore, after the heating unit 21 performs the heating and temperature raising action, the temperature of the windshield mechanism 2 continues to be detected by the temperature detection module, and it is continued to be determined whether the temperature of the windshield mechanism 2 reaches the preset temperature threshold, until it is determined that the temperature of the windshield mechanism 2 reaches the preset temperature threshold. When the temperature detection module detects that the temperature of the windshield mechanism 2 reaches the preset temperature threshold and is maintained for a certain period of time (for example, 60 seconds), the control unit can control the heating unit 21 to be powered off to stop heating, which can not only solve the problem of condensed water generated at the air outlet 111, but also avoid waste of resources.

[0068] In addition, if Figure 7 As shown, the process before step S101 includes: steps S201 to S202.

[0069] Step S201, detecting the temperature of the air outlet 111 of the air conditioner, and comparing the temperature of the air outlet 111 with a preset second temperature threshold;

[0070] Step S202: If the temperature of the air outlet 111 is lower than a preset second temperature threshold, the temperature of the wind shielding mechanism 2 is detected.

[0071] Before detecting the temperature of the wind shielding mechanism 2, the present embodiment first detects the temperature of the air outlet 111 of the air conditioner to confirm whether condensation water will be generated at the temperature of the air outlet 111. For example, when the air conditioner is running in heating mode, the temperature of the air outlet 111 will be higher, so no condensation water will be generated, and when the air conditioner is running in cooling mode, the temperature of the air outlet 111 will be lower, and condensation water may be generated at this time, so the detected temperature of the air outlet 111 is compared with a preset temperature threshold (the temperature threshold here can be the same as or different from the temperature threshold corresponding to the temperature of the wind shielding mechanism 2), and when the temperature of the air outlet 111 is lower than the preset temperature threshold, the temperature of the wind shielding mechanism 2 is detected, and when the temperature of the air outlet 111 is higher than or equal to the preset temperature threshold, the temperature of the wind shielding mechanism 2 may be temporarily not detected.
