[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Reference below Figure 1-Figure 6 The air conditioner 100 according to the embodiment of the present invention is described, wherein the air conditioner 100 may be a split wall-mounted air conditioner or a split floor-standing air conditioner.

[0033] like Figure 1-Figure 6 As shown, the air conditioner 100 according to the embodiment of the present invention comprises: a housing 1, a fresh air switch 2 and a heating device 3, wherein the housing 1 is provided with an indoor air inlet 10, a fresh air inlet 11, an air outlet 12 and a fresh air outlet 13. In some examples of the present invention, such as Figure 1 As shown, the air conditioner 100 is a split wall-mounted type, with the indoor air inlet 10 located at the top of the casing 1, the fresh air inlet 11 located at the rear surface of the casing 1, the fresh air outlet 13 located on the front panel of the casing 1, and the air outlet 12 located at the front lower part of the casing 1. Specifically, the fresh air outlet 13 is arranged above the air outlet 12, so that the fresh air can be blown to the top of the room, and the fresh air can be distributed in the indoor environment from top to bottom, thereby improving the fresh air effect. Figure 1 In the specific example shown, the front panel of the housing 1 is provided with a plurality of ventilation holes to define a fresh air outlet 13, thereby achieving a windless effect and improving comfort.

[0034] The fresh air switch 2 is disposed at the fresh air inlet 11 to open or close the fresh air inlet 11. Specifically, the fresh air switch 2 can be rotatable, movable or retractable to open or close the fresh air inlet 11.

[0035] The heating device 3 is arranged on the fresh air switch 2 to heat the fresh air entering the fresh air inlet 11. Specifically, the heating device 3 can be a resistance wire heater, which can heat the outdoor air (i.e., fresh air) when powered on, and has a simple and reliable structure. Of course, it can be understood that the structure of the heating device 3 is not limited to this, as long as the heating device 3 can heat the fresh air. For example, the heating element of the heating device 3 can be a ceramic electric heating tube or an infrared heating tube. Among them, the infrared heating tube uses the infrared spectrum radiation principle to generate electromagnetic waves, thereby heating and heating the surrounding air. Compared with the resistance wire heating tube, it is safer and heats evenly and quickly. The ceramic electric heating tube contains alloy wire wound around the ceramic block, and the outer shell is wrapped with metal. It is characterized by fast heat transfer and good thermal insulation.

[0036] Specifically, the air conditioner 100 may further include components such as an indoor heat exchanger. The indoor heat exchanger is disposed in the housing 1. Indoor air enters the housing 1 through the indoor air inlet 10 and is sent to the indoor environment through the air outlet 12 after heat exchange through the indoor heat exchanger. When outdoor air needs to be introduced, the fresh air switch 2 opens the fresh air inlet 11, and the outdoor air enters the housing 1 through the fresh air inlet 11 and is sent to the indoor environment through the fresh air outlet 13.

[0037] When there is no need to introduce fresh air into the indoor environment, the fresh air switch 2 closes the fresh air inlet 11 to protect the air conditioner 100, preventing debris or small animals from entering the casing 1 through the fresh air inlet 11, and also preventing outdoor air from flowing back into the casing 1.

[0038] When the air conditioner 100 is operated in a low outdoor ambient temperature, such as in winter, when the fresh air switch 2 opens the fresh air inlet 11 to allow outdoor air to enter the fresh air inlet 11, the heating device 3 can be operated to heat the outdoor air entering the fresh air inlet 11, so that the cold air becomes hot air, thereby preventing the cold and hot air from intersecting at the fresh air inlet 11 to produce condensation water, and further preventing the condensation water from freezing and causing the fresh air switch 2 to become stuck and fail. Therefore, when the fresh air function is not needed, the fresh air switch 2 can be closed normally to block the cold air from entering the casing 1, solving the complaint of condensation water generated at the fresh air outlet 13.

[0039] According to the air conditioner 100 of the embodiment of the present invention, by arranging the heating device 3 on the fresh air switch 2, it is possible to prevent the fresh air switch 2 from being stuck and failing due to condensation water freezing. Therefore, when the fresh air function is not needed, the fresh air switch 2 can be closed normally to block cold air from entering the housing 1 and prevent the fresh air outlet 13 from generating condensation water.

[0040] In some embodiments of the present invention, the air conditioner 100 includes a first fan and a second fan, which are respectively arranged in the casing 1, and the first fan and the second fan operate independently. When the first fan operates, indoor air can be sucked into the casing 1 from the indoor air inlet 10 and heat exchanged with the indoor heat exchanger, and the heat-exchanged air is blown out from the air outlet 12. When the second fan operates, outdoor air can be sucked into the casing 1 from the fresh air inlet 11 and sent into the indoor environment from the fresh air outlet 13.

[0041] Of course, it is understandable that the number of fans is not limited to this, as long as it is ensured that indoor air can be sucked into the casing 1 from the indoor air inlet 10 and outdoor air can be sucked into the casing 1 from the fresh air inlet 11. For example, in other embodiments of the present invention, the air conditioner 100 includes an indoor fan, which is arranged in the casing 1. When the indoor fan is running, indoor air can be sucked into the casing 1 from the indoor air inlet 10, and when the fresh air inlet 11 is opened, outdoor air can be sucked into the casing 1 through the fresh air inlet 11.

[0042] According to some embodiments of the present invention, the air conditioner 100 includes a fresh air component 4, which is arranged in the housing 1. The fresh air component 4 may include at least one of a fan and a filter assembly. In a specific example of the present invention, the fresh air component 4 includes a fan, so that whether to turn on the fresh air mode can be independently controlled.

[0043] In some embodiments of the present invention, Figure 2-Figure 6 As shown, the fresh air component 4 is provided with a fresh air passage 40 connected to the fresh air inlet 11 and the fresh air outlet 13, and the fresh air switch 2 is arranged in the fresh air passage 40. Therefore, it is not only convenient to install the fresh air switch 2, but also the fresh air inlet 11 can be accurately opened or closed. In some examples of the present invention, the fresh air switch 2 is rotatably arranged in the fresh air passage 40. Thus, the opening method of the fresh air switch 2 is simple and reliable. Specifically, the fresh air switch 2 can be flipped between a horizontal position and a vertical position, and the opening of the fresh air inlet 11 is the largest when the fresh air switch 2 is rotated to the horizontal position. When the fresh air switch 2 is rotated to the vertical position, the fresh air switch 2 cooperates with the inner peripheral wall of the fresh air passage 40 to block the fresh air passage 40 and then close the fresh air inlet 11. Preferably, the fresh air switch 2 can be formed as a circular plate, so that the structure of the fresh air switch 2 is simple.

[0044] Specifically, the fresh air passage 40 can be independently provided with the heat exchange passage in the housing 1, and the indoor heat exchanger is provided in the heat exchange passage, that is, the fresh air enters the fresh air passage 40 from the fresh air inlet 11 and is directly discharged from the fresh air outlet 13. Thus, the fresh air function and the heat exchange function can be separated, which is convenient for controlling the air conditioner 100. Of course, it is understandable that the fresh air passage 40 can also be connected with the heat exchange passage in the housing 1 (always connected or connected as needed), a part of the fresh air is discharged from the fresh air outlet 13, and the other part of the fresh air can be discharged from the air outlet 12 through the heat exchange passage.

[0045] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the heating device 3 includes a heating element 30 and a mounting bracket 31, the heating element 30 is arranged on the mounting bracket 31, and the mounting bracket 31 is fixed on the fresh air switch 2. This facilitates the assembly of the heating device 3 and avoids damage to the heating element 30 during the assembly process. Furthermore, each heating device 3 may include a plurality of mounting brackets 31, the heating element 30 is arranged on the plurality of mounting brackets 31, and the plurality of mounting brackets 31 are respectively fixed on the fresh air switch 2, thereby improving the installation stability. Figure 4 In the example shown, the heating device 3 includes two mounting brackets 31, which are fixed at both ends of the heating element 30 and are fixed adjacent to the edge of the fresh air switch element 2. This can reduce the obstruction of the heating device 3 to the fresh air circulation while ensuring the installation stability, thereby ensuring the fresh air intake.

[0046] like Figure 4 As shown, in some examples of the present invention, the heating element 30 extends in a meandering manner, so that the heating capacity of the heating device 3 can be increased.

[0047] Furthermore, if Figure 4 As shown, the fresh air switch 2 is provided with a first mounting hole 20, the mounting bracket 31 is provided with a second mounting hole 310, and the fixing connecting member cooperates with the first mounting hole 20 and the second mounting hole 310 respectively to fix the mounting bracket 31 on the fresh air switch 2, wherein the fixing connecting member can be a screw, a bolt or other element. This facilitates the assembly of the mounting bracket 31. Of course, it is understandable that the mounting bracket 31 can also be fixed to the fresh air switch 2 by other means, such as snap connection, welding, etc.

[0048] like Figure 3-Figure 6 As shown, in some embodiments of the present invention, heating devices 3 are provided on opposite side walls of the fresh air switch 2. Thus, the fresh air can be effectively heated to avoid condensation. Furthermore, the heating devices 3 on the opposite side walls of the fresh air switch 2 can be controlled independently or in a linkage manner.

[0049] In some embodiments of the present invention, the air conditioner 100 has a control device, which is connected to the fresh air switch 2 and the heating device 3 respectively to control the fresh air switch 2 and the heating device 3 to operate independently. "The fresh air switch 2 and the heating device 3 operate independently" means that the working state of the fresh air switch 2 and the operating state of the heating device 3 are independently controlled. When the fresh air switch 2 opens the fresh air inlet 11, the control device controls whether the heating device 3 is turned on according to demand (for example, according to the detected outdoor ambient temperature or the user's determination whether the heating needs to be turned on). This allows for more intelligent control and energy saving.

[0050] Of course, it is understandable that the control method of the fresh air switch 2 and the heating device 3 is not limited to this. For example, the fresh air switch 2 and the heating device 3 can be controlled in linkage. For example, when the control device controls the fresh air switch 2 to open the fresh air inlet 11, the heating device 3 is controlled to be turned on in linkage. When the control device controls the fresh air switch 2 to close the fresh air inlet 11, the heating device 3 is controlled to be turned off in linkage, thereby making the control method simple and reliable.

[0051] Specifically, the heating device 3 can be connected to the control device through wires. When the air conditioner 100 is turned on, the user can use the remote control to turn on the fresh air switch 2. After the fresh air switch 2 opens the fresh air inlet 11, the heating function of the heating device 3 can be turned on.

[0052] Other components of the air conditioner 100 according to the embodiment of the present invention, such as a chassis and operations, are well known to those skilled in the art and will not be described in detail here.
