[0041] Embodiments of the present application are described in detail below with reference to the attached drawings, which show by way of example, embodiments in which the same or similar elements or elements having the same or similar functions are denoted by the same or similar reference numerals throughout the drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0042] The air conditioner 100 according to an embodiment of the present application is described below with reference to Figure 1 and Figure 2 .

[0043] As shown in Figure 1 and Figure 2 , the air conditioner 100 according to an embodiment of the present application includes an air conditioner main body 10, a hot air flow channel 20, a cold air flow channel 30, an electric control 40, and a switch mechanism 50.

[0044] The hot air flow channel 20 and the cold air flow channel 30 are arranged on the air conditioner main body 10, the hot air flow channel 20 is used to take away the heat generated during heat exchange of the air conditioner main body 10, the cold air flow channel 30 is used to take away the cold generated during heat exchange of the air conditioner main body 10, the cold air flow channel 30 is provided with a flow guide port 301; the electric control 40 is arranged adjacent to the flow guide port 301; the switch mechanism 50 is used to open or close the flow guide port 301, and when the switch mechanism 50 opens the flow guide port 301, part of the cold air in the cold air flow channel 30 can flow through the electric control 40.

[0045] It should be noted that the air conditioner 100 can be a window type air conditioner or other forms of mobile air conditioner, and other component structures of the air conditioner 100, for example, the condenser 801, the evaporator 802, the compressor and the like structures and installation positions can refer to the prior art, and will not be described here. The electric control 40 is used to control the work of the compression element, and when the air conditioner 100 works, the hot air flow channel 20 takes away the heat released by the condenser 801 during heat exchange, and the cold air flow channel 30 takes away the cold released by the evaporator 802 during heat exchange. The air outlet of the hot air flow channel 20 and the cold air flow channel 30 can be specifically arranged according to the situation, for example, when the air conditioner 100 is used for heating, the air outlet of the hot air flow channel 20 can be located in front of the air conditioner 100 and blow towards the user; when the air conditioner 100 is used for cooling, the air outlet of the cold air flow channel 30 can be located in front of the air conditioner 100 and blow towards the user.

[0046] During the working process of the air conditioner 100, the switch mechanism 50 can selectively open or close the flow guide port 301, so that when the temperature of the electric control 40 is relatively high, part of the cold air in the cold air flow channel 30 is guided to the electric control 40, and the cold air passing through the electric control 40 can not only avoid the condensation problem of the electric control 40, but also improve the heat exchange capacity of the electric control 40, improve the operation frequency of the compressor, and make the air conditioner 100 have greater cold or heat.

[0047] According to the air conditioner 100 of the embodiment of the present application, the flow guide port 301 is arranged on the cold air flow channel 30, the electric control 40 is arranged adjacent to the flow guide port 301, and the switch mechanism 50 is used to open or close the flow guide port 301, so that when the switch mechanism 50 opens the flow guide port 301, part of the cold air in the cold air flow channel 30 can flow through the electric control 40. When the air conditioner 100 works, the cold air in the cold air flow channel 30 can be guided to the electric control 40 under the cooperation of the flow guide port 301 and the switch mechanism 50, the condensation problem of the electric control 40 can be avoided, the heat exchange capacity of the electric control 40 can be improved, the air conditioner 100 can achieve greater cold or heat, and under the premise that a smaller displacement compressor can meet the overall cooling or heating needs of a room, the overall size of the air conditioner 100 is smaller and the cost is lower.

[0048] In some embodiments of the present application, for example, Figure 1As shown, the switch mechanism 50 includes a flow guiding portion 501, which is capable of moving into the cold air flow channel 30 when the switch mechanism 50 is in the open state, so as to guide part of the cold air in the cold air flow channel 30 to flow towards the electric control 40. When the switch mechanism 50 is in the closed state, the flow guiding portion 501 is located outside the cold air flow channel 30 and does not affect the flow of the cold air in the cold air flow channel 30. When the switch mechanism 50 is in the open state, the flow guiding portion 501 moves to the cold air flow channel 30, can intercept the cold air in the cold air flow channel 30, and guide the intercepted cold air to the electric control 40, thereby increasing the amount of air flowing through the electric control 40, so that the heat exchange effect of the electric control 40 is better.

[0049] In some embodiments of the present application, as shown in Figure 1 As shown, the flow guiding portion 501 includes a first portion 5011 and a second portion 5012 connected to each other, and an included angle is formed between the first portion 5011 and the second portion 5012. When the switch mechanism 50 is in the closed state, the first portion 5011 closes the flow guiding port 301. It can be understood that the first portion 5011 and the second portion 5012 form a "V" shape structure. When the switch mechanism 50 is in the open state, the first portion 5011 can move into the cold air flow channel 30. At this time, due to the "V" shape structure, the cold air in the cold air flow channel 30 can be intercepted, and the intercepted cold air flows along the first portion 5011 and is diverted at the second portion 5012 to flow towards the electric control 40.

[0050] In some embodiments of the present application, as shown in Figure 1 As shown, the included angle between the first portion 5011 and the second portion 5012 is 90 degrees, that is, the first portion 5011 and the second portion 5012 are both arranged vertically. The first portion 5011 can extend along the flow direction of the cold air in the cold air flow channel 30. This design is relatively simple and has low manufacturing difficulty.

[0051] Of course, the above is only an example. The included angle between the first portion 5011 and the second portion 5012 can also be other values, which can be specifically set according to the situation, as long as the cold air can be guided to the electric control 40. Here, no further description is given.

[0052] In some embodiments, the first portion 5011 and the second portion 5012 can be configured as a plate, which can save materials, has low manufacturing difficulty, and reduces cost.

[0053] In some embodiments of the present application, as shown in Figure 1 As shown, the air conditioner 100 can further include a second flow guiding plate 805, which is parallel to the second portion 5012 and is arranged with a spacing therebetween, that is, the second flow guiding plate 805 and the second portion 5012 can define a flow guiding channel, so as to guide the cold air to flow towards the electric control 40 along the flow guiding channel.

[0054] In some embodiments of the present invention, the second guide plate 805 may be disposed on the outer wall of the cold air flow channel 30. Specifically, the second guide plate 805 is installed on the outer wall of the cold air flow channel 30 by means of fasteners, such as rivets or screws. The second guide plate 805 may also be fixed to the outer wall of the cold air flow channel 30 by welding.

[0055] In some embodiments of the present invention, such as Figure 1 As shown, the second drainage plate 805 can also be disposed on the electrical control unit 40. Specifically, the second drainage plate 805 is installed on the electrical control box of the electrical control unit 40 by means of fasteners, such as rivets or screws. The second drainage plate 805 can also be fixed to the electrical control box of the electrical control unit 40 by welding.

[0056] In some embodiments of the present invention, such as Figure 2 As shown, the control unit 40 includes a control unit body 410 and a heat sink 420. The control unit body 410 is mounted on the air conditioner body 10. The heat sink 420 is located at the upper end of the control unit body 410 and below the air inlet 301. The heat sink 420 is used to dissipate heat from the control unit body 410. When the cold air flows through the heat sink 420, it can accelerate the air circulation and significantly reduce the temperature of the heat sink 420, thereby improving the heat dissipation effect of the heat sink 420 on the control unit body 410.

[0057] In some embodiments of the present invention, such as Figure 1 As shown, the second part 5012 extends along the length of the heat sink 420. In this way, the flow path of the cold air can be set along the length of the heat sink 420, and the cold air is blown horizontally to the heat sink 420, resulting in a larger contact surface and more efficient air circulation and cooling on the heat sink 420.

[0058] In some embodiments of the present invention, the extension direction of the second portion 5012 may also form an angle with the length direction of the heat sink 420, as long as the cold air drawn along the second portion 5012 can cover the heat sink 420.

[0059] In some embodiments of the present invention, the main body 410 of the electrical control unit includes an electrical control box and an electrical control board. The electrical control board is disposed inside the electrical control box, and a heat sink 420 is disposed on the electrical control box and connected to the electrical control board. The electrical control board may refer to a PCB circuit board, used to control the operation of the compressor and the fan. To avoid condensation problems, the electrical control board and the heat sink 420 may be arranged in a partitioned manner, with cold air only flowing through the area of ​​the heat sink 420. The exterior of the electrical control box may be lined with sponge for anti-condensation design. The electrical control box may also adopt a sandwich hollow structure for anti-condensation design.

[0060] In some embodiments of the present application, the heat dissipation member 420 can be a heat dissipation fin or a metal heat dissipation plate. The heat dissipation fin can be a heat dissipation fin or a multi-layer heat dissipation fin structure. When the heat dissipation member 420 is a heat dissipation fin, the extension direction of the second portion 5012 is parallel to the length direction of the heat dissipation fin, and the heat dissipation effect of the heat dissipation fin is better.

[0061] In some embodiments of the present application, as shown in Figure 1 The cold air flow channel 30 has a cold air outlet 302 and a guide wall 303, and the guide opening 301 is arranged on the guide wall 303. The part of the guide wall 303 close to the first portion 5011 is parallel to the first portion 5011. The cold air in the cold air flow channel 30 is blown outwards through the cold air outlet 302, and the guide wall 303 plays a guiding role to guide the flow of cold air and reduce wind loss. The part of the guide wall 303 is parallel to the first portion 5011, which can better guide the flow of the cold air.

[0062] In some embodiments of the present application, the guide wall 303 can be an arc-shaped side wall structure to ensure smooth flow of cold air and avoid wind speed loss.

[0063] In some embodiments of the present application, as shown in Figure 1 The air conditioner main body 10 is provided with a mounting space 101, and the hot air flow channel 20, the cold air flow channel 30 and the electric control 40 are arranged in the mounting space 101. The mounting space 101 provides a mounting space to avoid the hot air flow channel 20, the cold air flow channel 30 and the electric control 40 exposed, which can play a role in aesthetics and protection.

[0064] In some embodiments of the present application, as shown in Figure 1 The cold air flow channel 30 is arranged on the front side of the hot air flow channel 20, the front end of the cold air flow channel 30 is provided with a cold air outlet 302, the rear end of the hot air flow channel 20 is provided with a hot air outlet 201, the rear wall of the mounting space 101 is provided with a hot air inlet 102 communicating with the hot air flow channel 20, and the left wall or the right wall of the mounting space 101 is provided with a cold air inlet 103 communicating with the cold air flow channel 30. That is, the cold air flow channel 30 can constitute the indoor side of the air conditioner 100, and the hot air flow channel 20 constitutes the outdoor side of the air conditioner 100, so that the air can circulate in and out in the front and rear directions of the whole machine. When the air conditioner 100 works, cold air can be blown forward, and the air in the cold air flow channel 30 can flow from the side to the front, and the hot air flow channel 20 on the rear side can realize the air flow from the rear to the rear. When the user is in front of the air conditioner 100, the noise on the front side of the air conditioner 100 can be reduced to the greatest extent, and the user experience can be improved.

[0065] Specifically, the cold air inlet 103 can be arranged on the left side wall of the installation space 101, and the electric control 40 is arranged in the right side region of the installation space 101. Alternatively, the cold air inlet 103 can be arranged on the right side wall of the installation space 101, and the electric control 40 is arranged in the left side region of the installation space 101.

[0066] In some embodiments of the present application, the cold air flow channel 30 is arranged at the rear side of the hot air flow channel 20, the rear end of the cold air flow channel 30 is provided with a cold air outlet 302, the rear side wall of the installation space 101 is provided with a cold air inlet 103 communicating with the cold air flow channel 30, the front end of the hot air flow channel 20 is provided with a hot air outlet 201, and the left side wall or the right side wall of the installation space 101 is provided with a hot air inlet 102 communicating with the hot air flow channel 20. That is, when the air conditioner 100 is working, hot air can be blown forward, and air in the hot air flow channel 20 can be in a side-in front-out mode, while the cold air flow channel 30 at the rear side can realize air in a rear-in rear-out mode, so that the noise on the front side of the air conditioner 100 can be reduced to the greatest extent when a user is in front of the air conditioner 100, and the user experience can be improved.

[0067] Specifically, the hot air inlet 102 can be arranged on the left side wall of the installation space 101, and the electric control 40 is arranged in the right side region of the installation space 101. Alternatively, the hot air inlet 102 can be arranged on the right side wall of the installation space 101, and the electric control 40 is arranged in the left side region of the installation space 101.

[0068] In some embodiments of the present application, as shown in Figure 1 The condenser 801, the evaporator 802, the compressor and other structures are arranged in the installation space 101. The condenser 801 can be arranged between the hot air flow channel 20 and the hot air inlet 102, and the hot air flow channel 20 is provided with a hot air through hole facing the condenser 801, so as to ensure that air enters the hot air flow channel 20 through the hot air inlet 102, the condenser 801 and the hot air through hole. The evaporator 802 can be arranged between the cold air flow channel 30 and the cold air inlet 103, and the cold air flow channel 30 is provided with a cold air through hole facing the evaporator 802, so as to ensure that air enters the cold air flow channel 30 through the cold air inlet 103, the evaporator 802 and the cold air through hole.

[0069] In some embodiments of the present application, as shown in Figure 1 The air conditioner 100 further comprises a hot air fan wheel 803 and a cold air fan wheel 804, the hot air fan wheel 803 is arranged in the hot air flow channel 20, and the cold air fan wheel 804 is arranged in the cold air flow channel 30. The hot air fan wheel 803 is driven by the hot air fan connected thereto, so as to drive air to enter the hot air flow channel 20 through the hot air inlet 102, the condenser 801 and the hot air through hole. The cold air fan wheel 804 is driven by the cold air fan connected thereto, so as to drive air to enter the cold air flow channel 30 through the cold air inlet 103, the evaporator 802 and the cold air through hole.

[0070] In some embodiments of the present application, the hot air impeller 803 and the cold air impeller 804 are both cross-flow impellers. The hot air impeller 803 is arranged in the vertical direction, and drives air to flow in the horizontal direction when rotating. The cold air impeller 804 is arranged in the vertical direction, and drives air to flow in the horizontal direction when rotating.

[0071] In some embodiments of the present application, as shown in Figure 1 The projections of the hot air flow channel 20 and the cold air flow channel 30 on the vertical plane arranged in the front-rear direction at least partially overlap. In this way, the hot air impeller 803 and the cold air impeller 804 can be arranged more compactly in the installation space 101, and the overall volume of the air conditioner 100 can be reduced, which is conducive to miniaturization of the entire machine.

[0072] Specifically, as shown in the drawings, the hot air flow channel 20 can be configured as a hot air duct volute, and the flow channel is formed in the hot air duct volute. The cold air flow channel 30 can be configured as a cold air duct volute, and the flow channel is formed in the cold air duct volute. The hot air duct volute and the cold air duct volute are arranged staggered in the left-right direction and partially overlap in the front-rear direction.

[0073] In some embodiments of the present application, the hot air duct volute and the cold air duct volute are arranged in a center-to-center manner.

[0074] In some embodiments of the present application, as shown in Figure 1 The switch mechanism 50 is movably arranged on the cold air flow channel 30, or the switch mechanism 50 is pivotally arranged on the cold air flow channel 30. It can be understood that the switch mechanism 50 can switch between the open state and the closed state by moving in the horizontal direction, or can switch between the open state and the closed state by rotating.

[0075] In some embodiments of the present application, when the switch mechanism 50 is movably arranged on the cold air flow channel 30, the switch mechanism 50 can further include a telescopic drive member, and the output end of the telescopic drive member is connected to the flow guide part 501. Specifically, the output end of the telescopic drive member can be connected to the second part 5012. When the telescopic drive member drives the flow guide part 501 to move in the direction towards the flow port 301 (i.e. the direction from left to right in the drawing), the flow guide part 501 can open the flow port 301. When the telescopic drive member drives the flow guide part 501 to move in the direction away from the flow port 301 (i.e. the direction from right to left in the drawing), the flow guide part 501 can close the flow port 301.

[0076] In some embodiments of the present application, the telescopic drive member can be any one of an electric push rod, a hydraulic cylinder, and a pneumatic cylinder.

[0077] In some embodiments of the present invention, when the switching mechanism 50 is pivotally mounted on the cold air duct 30, the switching mechanism 50 may further include a rotary drive member, the output end of which is connected to the drainage portion 501. Specifically, the output end of the rotary drive member may be connected at the junction of the second portion 5012 and the first portion 5011, and the output end of the rotary drive member may rotate in a vertical direction. For example, the rotary drive member may rotate clockwise in a vertical direction to open the drainage port 301 of the drainage portion 501, or it may rotate counterclockwise in a vertical direction to close the drainage port 301 of the drainage portion 501.

[0078] In some embodiments of the present invention, the rotary drive can be any one of a motor, a rotary cylinder, or a rotary hydraulic cylinder.

[0079] A specific embodiment of the air conditioner 100 of the present invention will now be described with reference to the accompanying drawings.

[0081] The air conditioner body 10 has an installation space 101, and the hot air duct 20, the cold air duct 30 and the electrical control 40 are located in the installation space 101.

[0092] In summary, the window air conditioner constructed using the air conditioner 100 of the present invention has an air inlet 301 on the cold air flow channel 30, and an electrical control 40 is disposed adjacent to the air inlet 301. The switching mechanism 50 is used to open or close the air inlet 301. When the switching mechanism 50 opens the air inlet 301, some of the cold air in the cold air flow channel 30 can flow through the electrical control 40. When the air conditioner 100 is running, the cold air in the cold air flow channel 30 can be guided to the electrical control 40 with the cooperation of the air inlet 301 and the switching mechanism 50, avoiding the condensation problem of the electrical control 40, improving the heat exchange capacity of the electrical control 40, so that the air conditioner 100 can meet the overall cooling needs of the room with a smaller displacement compressor, with a smaller body size and lower cost, and can reduce the maximum temperature of the electrical control 40 from 113 degrees to 43 to 45 degrees while meeting the required cooling capacity.

[0093] like Figure 4 As shown, according to an embodiment of the present invention, the control method for an air conditioner 100, wherein the air conditioner 100 is the air conditioner 100 described above, includes:

[0094] Step S1: Set the preset temperature of the electrical control 40.

[0095] A preset temperature is set for the electrical control component 40. The preset temperature can be understood as the critical temperature that affects the performance of the electrical control component 40. Exceeding this preset temperature will affect the operating frequency of the compressor. For example, the preset temperature t0 is 95℃~120℃, that is, t0 can be any value among 95℃, 100℃, 105℃, 110℃, 115℃, and 120℃. This is just an example and is not limited to this. As long as t0 is a value within the range of 95℃~120℃, it is acceptable.

[0096] The temperature of the electrical control unit 40 can be collected by a corresponding detection device, such as a temperature sensor. As mentioned above, the electrical control unit 40 includes an electrical control body 410 and a heat sink 420. The heat sink 420 can be a heat sink. Therefore, the electrical control unit 40 collects the temperature of the electrical control board in the electrical control body 410.

[0097] Step S2: Open or close the drain port 301 according to the preset temperature control switch mechanism 50.

[0098] According to the control method of the air conditioner 100 of the present invention, by setting a preset temperature of the electrical control 40, the control switch mechanism 50 is opened or closed according to the preset temperature. When the air conditioner 100 is running, the cold air from the cold air flow channel 30 can be diverted to the electrical control 40, avoiding condensation problems in the electrical control 40, improving the heat exchange capacity of the electrical control 40, enabling the air conditioner 100 to achieve greater cooling or heating capacity, and under the premise that a smaller displacement compressor can meet the overall cooling or heating needs of the room, the overall size of the unit is smaller and the cost is lower.

[0099] In some embodiments of the present application, as shown in Figure 5 Step S2 comprises:

[0100] Step S21: When the temperature of the electric control 40 is greater than the preset temperature, the switching mechanism 50 opens the flow guide port 301 to guide the cold air to the electric control 40 for heat exchange.

[0101] Step S22: When the temperature of the electric control 40 is less than or equal to the preset temperature, the switching mechanism 50 closes the flow guide port 301, and the cold air is blown out by the cold air flow channel 30.

[0102] In some embodiments of the present application, as shown in Figure 5 Step S21, when the temperature of the electric control 40 is greater than the preset temperature, the switching mechanism 50 opens the flow guide port 301, and then comprises:

[0103] Step S211: According to the temperature of the electric control 40 and the preset temperature, the opening degree of the switching mechanism 50 opening the flow guide port 301 is controlled. It can be understood that according to the difference between the temperature of the electric control 40 and the preset temperature, the opening degree of the switching mechanism 50 opening the flow guide port 301 can be adaptively adjusted as needed. For example, the greater the temperature of the electric control 40 exceeds the preset temperature, the greater the percentage of the opening degree of the switching mechanism 50 opening the flow guide port 301.

[0104] Specifically, the percentage of the opening degree of the switching mechanism 50 opening the flow guide port 301 is n%, and n can be 1, 2, 3, … The greater the temperature of the electric control 40 exceeds the preset temperature, the greater the value of n. Wherein, the opening degree of the switching mechanism 50 opening the flow guide port 301 can be controlled by a driving member, as described above, by controlling the extension length of the telescopic driving member or the rotation angle of the rotary driving member, thereby playing the role of the opening degree of the flow guide port 301.

[0105] In some embodiments of the present application, as shown in Figures 3 to 6 Step S21, when the temperature of the electric control 40 is greater than the preset temperature, the switching mechanism 50 opens the flow guide port 301, and then further comprises:

[0106] Step S212: Increase the operating frequency of the compressor and the rotating speed of the hot air fan and the cold air fan. For example, the operating frequency of the compressor can be preset as fc, the rotating speed of the hot air fan as Win, and the rotating speed of the cold air fan as Wout. When the temperature of the electric control 40 is greater than the preset temperature, the switching mechanism 50 opens the flow guide port 301, and the operating frequency of the compressor can be increased from fc to fn, the rotating speed of the hot air fan from Win to Winn, and the rotating speed of the cold air fan from Wout to Woutn.

[0107] Before the switch mechanism 50 closes the air flow port 301 in step S22, it further includes step S221: reducing the operating frequency of the compressor, reducing the rotating speed of the hot air fan and the cold air fan. It can be understood that the operating frequency of the compressor is reduced from fc to the rated frequency, the rotating speed of the hot air fan is reduced to be lower than Win, and the rotating speed of the cold air fan is reduced to be lower than Woutn.

[0108] A specific embodiment of the control method of the air conditioner 100 will be described below in combination with ​

[0109] Step S1: presetting the preset temperature t0 of the electric control 40, presetting the operating frequency fc of the compressor, presetting the rotating speed Win of the hot air fan, presetting the rotating speed Wout of the cold air fan, and detecting the temperature t of the electric control 40. The preset temperature t0 is 95℃.

[0110] Step S2: controlling the switch mechanism 50 to open or close the air flow port 301 according to the preset temperature.

[0111] When the temperature of the electric control 40 is greater than the preset temperature 95℃, the following steps are executed:

[0112] Step S21: the switch mechanism 50 opens the air flow port 301 to guide the cold air to the electric control 40 for heat exchange.

[0113] Step S211: controlling the switch mechanism 50 to open or close the air flow port 301 according to the temperature of the electric control 40 and the preset temperature.

[0114] Step S212: increasing the operating frequency of the compressor, increasing the rotating speed of the hot air fan and the cold air fan

[0115] When the temperature of the electric control 40 is less than or equal to the preset temperature 95℃, the following steps are executed:

[0116] Step S221: reducing the operating frequency of the compressor, reducing the rotating speed of the hot air fan and the cold air fan.

[0117] Step S222: the switch mechanism 50 closes the air flow port 301, and the cold air is blown out by the cold air flow channel 30.

[0118] ​In summary, the window air conditioner formed by the air conditioner 100 of the present application can avoid the condensation problem of the electric control 40 by setting the preset temperature of the electric control 40, controlling the opening or closing of the flow guide opening 301 according to the preset temperature, guiding the cold air of the cold air flow channel 30 to the electric control 40 when the air conditioner 100 is running, improving the heat exchange capacity of the electric control 40, and reducing the maximum temperature of the electric control 40 from 113 degrees to 43 degrees to 45 degrees under the premise that the air conditioner 100 can meet the overall refrigeration needs of the room by using a smaller displacement compressor, and the size of the machine body is smaller, the cost is lower, and the maximum temperature of the electric control 40 can be reduced to 43 degrees to 45 degrees under the premise of meeting the required cooling capacity.
