[0043] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not used to limit the scope of the present utility model.

[0044] As described in the background art, in the related art, the circuit board is arranged in the circuit box, and the circuit box is installed in the internal space of the outdoor unit. The circuit box can complete the heat dissipation and insect prevention of the circuit board. However, the structure of the circuit box is complex, and the circuit box will also increase the cost of the whole machine, resulting in a complex assembly process and a high cost of the whole machine.

[0045] Therefore, the embodiments of the present application propose an outdoor unit and a heating and ventilation equipment, which are beneficial to reducing the cost of the whole machine and simplifying the assembly process while realizing the heat dissipation and insect prevention of the circuit board.

[0046] In the first aspect, the present application proposes an outdoor unit 10. As Figures 1 to 3 shown, the outdoor unit 10 includes a housing 100, a partition 200, a circuit board 300, and a first filter 400. The interior of the housing 100 has a receiving cavity 101. The partition 200 is arranged in the receiving cavity 101 to divide the receiving cavity 101 into a blower cavity 1011 and a compressor cavity 1012. The circuit board 300 is arranged in the compressor cavity 1012 and is connected to the partition 200. The housing 100 is also provided with a first ventilation opening 102 communicating with the compressor cavity 1012, and the first filter 400 covers the first ventilation opening 102.

[0047] In the present application, the outdoor unit 10 includes a housing 100, a partition 200, a circuit board 300, and a first filter 400. The housing 100 is the housing of the outdoor unit 10, and the housing 100 is usually composed of a chassis 110, a top cover 120, and a plurality of side plates connecting the chassis 110 and the bottom cover. The partition 200 is arranged in the receiving cavity 101 of the housing 100, thereby dividing the receiving cavity 101 into a blower cavity 1011 and a compressor cavity 1012. The blower cavity 1011 refers to the cavity for installing the blower 700, and the compressor cavity 1012 refers to the cavity for installing the compressor. The circuit board 300 is the circuit control board or main board of the outdoor unit 10 or the heating and ventilation equipment including the outdoor unit 10, which is used to control the operation of the whole machine system. The circuit board 300 includes a main board body and a plurality of electrical components arranged on the main board body.

[0048] For the outdoor unit 10 of the present application, the circuit board 300 is directly disposed within the compressor chamber 1012 and fixedly connected to the partition member 200, so that there is no need to additionally provide a circuit box for dissipating heat and preventing insects for the circuit board 300. In other words, the compressor chamber 1012 serves as the circuit box for the circuit board 300 in the related art. Further, the housing 100 of the outdoor unit is further provided with a first ventilation opening 102 communicating with the compressor chamber 1012, and the first filter screen 400 covers the first ventilation opening 102. The heat of the circuit board 300 can be dissipated to the outside through the first ventilation opening 102, and at the same time, the first filter screen 400 can prevent mosquitoes and insects from entering the compressor chamber 1012 through the first ventilation opening 102, so that the compressor chamber 1012 can also complete the work of dissipating heat and preventing insects for the circuit board 300. In this way, while ensuring heat dissipation and insect prevention of the circuit board 300, the cost of the whole machine can be reduced and the assembly process of the whole machine can be simplified.

[0049] It should be noted that the housing 100 of the outdoor unit 10 is of a split structure. Therefore, when assembling the housing 100, there will be an assembly gap between different components of the housing 100, and this assembly gap can serve as an air inlet, so as to form convective heat dissipation with the first ventilation opening 102, and further improve the heat dissipation effect of the compressor chamber 1012 on the circuit board 300. At the same time, the assembly gap is generally not too large, and it can also prevent mosquitoes and insects from entering.

[0050] Of course, other methods can also be used to improve the heat dissipation effect of the compressor chamber 1012 on the circuit board 300. For example, in some embodiments, as Figure 2 shown, the outdoor unit 10 further includes a second filter screen 500, and the housing 100 is further provided with a second ventilation opening 103 communicating with the compressor chamber 1012, and the second filter screen 500 covers the second ventilation opening 103. That is to say, in this embodiment, by additionally providing a second ventilation opening 103 communicating with the compressor chamber 1012 on the housing 100, the second ventilation opening 103 and the first ventilation opening 102 form convective heat dissipation, which is beneficial to further improving the heat dissipation effect of the compressor chamber 1012 on the circuit board 300. At the same time, the second ventilation opening 103 is covered by the second filter screen 500, which can also prevent mosquitoes and insects from entering, and further improve the insect prevention effect on the circuit board 300.

[0051] Optionally, the first filter screen 400 can cover the first ventilation opening 102 by means of welding, detachable connection, etc., and the second filter screen 500 can cover the second ventilation opening 103 by means of welding, detachable connection, etc. The present application does not limit this.

[0052] Optionally, in some embodiments, as Figure 2As shown, the outdoor unit 10 further includes a radiator 310 for dissipating heat from the circuit board 300. The radiator 310 is disposed in the fan chamber 1011 and connected to the back surface of the circuit board 300. By providing the radiator 310, the heat dissipation effect of the circuit board 300 can be further improved.

[0053] Optionally, the radiator 310 can be assembled from a plurality of heat dissipation fins.

[0054] Optionally, the radiator 310 is also connected to the separator 200 to improve the connection reliability of the radiator 310.

[0055] In some embodiments, both the first vent 102 and the second vent 103 are located on the side of the separator 200 close to the compressor chamber 1012. The first vent 102 is located on the upper surface of the housing 100, and the second vent 103 is located on the side wall of the housing 100. Since the heat of the circuit board 300 will heat the air, and the hot air will rise. In this embodiment, the first vent 102 is provided on the upper surface of the housing 100, so that the hot air can be discharged outdoors more smoothly and at the same time, the backflow of the hot air is avoided. The second vent 103 is provided on the side wall of the housing 100, and the position of the side wall is relatively low, so that the second vent 103 is easier to suck in the air in the surrounding environment. Thus, it is beneficial to further improve the heat dissipation effect of the convective heat dissipation. In addition, both the first vent 102 and the second vent 103 are located on the side of the separator 200 close to the compressor chamber 1012. Thus, the first vent 102 and the second vent 103 can be directly communicated with the compressor chamber 1012.

[0056] In other embodiments, as Figure 2 and Figure 3 shown, the first vent 102 is located on the side of the separator 200 close to the fan chamber 1011, the second vent 103 is located on the side of the separator 200 close to the compressor chamber 1012, the first vent 102 is located on the upper surface of the housing 100, the second vent 103 is located on the side wall of the housing 100, and the first vent 102 is also communicated with the fan chamber 1011.

[0057] In this embodiment, the first ventilation opening 102 is located on the upper surface of the housing 100, and the second ventilation opening 103 is located on the side wall of the housing 100, which is conducive to improving the heat dissipation effect of convective heat dissipation. Further, the first ventilation opening 102 is located on the side of the partition member 200 close to the fan chamber 1011, and the first ventilation opening 102 is also communicated with the fan chamber 1011. That is to say, the first ventilation opening 102 is communicated with both the compressor chamber 1012 and the fan chamber 1011, and the first ventilation opening 102, the fan chamber 1011 and the compressor chamber 1012 are in a communicating state. The reason for such a setting is as follows. First, a fan 700 is provided in the fan chamber 1011. The fan 700 actively blows air and then blows the air out through the air outlet of the fan chamber 1011, which will form a negative pressure area in the fan chamber 1011. The first ventilation opening 102, the fan chamber 1011 and the compressor chamber 1012 are set to be in a communicating state, so that the hot air in the compressor chamber 1012 is affected by the negative pressure and enters the fan chamber 1011, and then the hot air is discharged through the air outlet of the fan chamber 1011. That is, forced convection of hot air from the compressor chamber 1012 to the fan chamber 1011 can be formed, which is conducive to further improving the heat dissipation effect on the circuit board 300. Second, the first ventilation opening 102 is located on the side of the partition member 200 close to the fan chamber 1011, so that the first ventilation opening 102 is not directly opposite to the circuit board 300. When it rains, external rainwater will not directly fall on the circuit board 300 through the first ventilation opening 102, which is also conducive to improving the waterproof effect of the circuit board 300.

[0058] In some embodiments, as Figures 2 to 4 shown, the first ventilation opening 102 is located on the side of the partition member 200 close to the fan chamber 1011 and is provided on the upper surface of the housing 100. The partition member 200 includes a main body portion 210 and a first flanging 220 connected to the main body portion 210. The first flanging 220 is bent toward the side of the main body portion 210 close to the fan chamber 1011 to form a notch 230 at the top of the main body portion 210. The compressor chamber 1012 is communicated with the first ventilation opening 102 through the notch 230.

[0059] In this embodiment, the first ventilation opening 102 is located on the side of the partition member 200 close to the fan chamber 1011. That is to say, the first ventilation opening 102 is directly communicated with the fan chamber 1011. In this case, it is also necessary to realize the communication between the first ventilation opening 102 and the compressor chamber 1012. Specifically, in this embodiment, the partition member 200 is designed. The main body portion 210 of the partition member 200 is used for fixedly connecting with the housing 100, and the first flanging 220 is bent towards the side of the main body portion 210 close to the fan chamber 1011 to form a notch 230 at the top of the main body portion 210. This notch 230 is the communication channel between the first ventilation opening 102 and the compressor chamber 1012. Through this design, not only the top of the partition member 200 is fixedly connected to the housing 100, but also the communication between the first ventilation opening 102 and the compressor chamber 1012 is realized.

[0060] It should be noted that in this embodiment, the first flanging 220 is formed by bending a part of the partition member 200, and the shape of the first flanging 220 conforms to the shape of the notch 230. Of course, in some other embodiments, the first flanging 220 can also be a separate component installed on the partition member 200, and the present application does not limit this.

[0061] In some embodiments, as Figures 2 to 4 shown, the first filter screen 400 includes a first filtering portion 410, a second filtering portion 420 and a mounting portion 430. The first filtering portion 410 is fixedly connected to the first ventilation opening 102, the mounting portion 430 is fixedly connected to the first flanging 220, one end of the second filtering portion 420 is connected to the first filtering portion 410, and the other end is connected to the mounting portion 430.

[0062] This embodiment further proposes the structure of the first filter screen 400. The first filtering portion 410 can prevent insects from entering through the first ventilation opening 102, and the second filtering portion 420 can prevent insects from entering the communication channel between the compressor chamber 1012 and the fan chamber 1011, which is beneficial to improving the insect prevention effect on the circuit board 300. At the same time, the first filtering portion 410 covers the first ventilation opening 102 and is fixedly connected to the first ventilation opening 102, and the mounting portion 430 is fixedly connected to the first flanging 220. Thus, the fixing and connection of the first filter screen 400 are also realized, which is also beneficial to improving the convenience of installing the first filter screen 400.

[0063] In some embodiments, as Figures 2 to 4As shown, the outdoor unit 10 further includes an air duct partition 600 disposed in the fan cavity 1011. The air duct partition 600 includes a first sub-board 610 and a second sub-board 620. The first sub-board 610 is disposed opposite to the first flanging 220. The first sub-board 610 is provided with a first opening 611. One end of the second sub-board 620 is connected to the first sub-board 610, and the other end is connected to the top of the housing 100. The first sub-board 610, the second sub-board 620, and the first flanging 220 construct an air duct. One end of the air duct is communicated with the first ventilation opening 102, and the other end is communicated with the first opening 611.

[0064] In this embodiment, an air duct partition 600 is further disposed in the fan cavity 1011. The air duct partition 600 and the first flanging 220 form an air duct from the fan cavity 1011 to the first ventilation opening 102. This air duct is zigzag-shaped. At the same time, the air duct is also communicated with the compressor cavity 1012. When it is rainy, under the structure of this labyrinth air duct, the water droplets thrown out by the fan 700 are difficult to enter the compressor cavity 1012 through the air duct, thereby further improving the waterproof effect on the circuit board 300.

[0065] In some embodiments, the first filter screen 400 has a plurality of first mesh holes. In any one of the first mesh holes, the distance between any two points on the edge of the first mesh hole is less than or equal to 5 mm. Thus, the blocking effect of the first mesh hole on mosquitoes is enhanced, which is beneficial to reducing the probability of mosquitoes entering the compressor cavity 1012, and further beneficial to improving the insect-proof effect on the circuit board 300.

[0066] It should be noted that the distance between any two points on the edge of the first mesh hole being less than or equal to 5 mm means that the length of the connecting line segment between any two different points on the edge of the first mesh hole is less than or equal to 5 mm. For example, if a certain first mesh hole is square, and the diagonal of the square is the longest line segment in the square, then as long as the diagonal of the square is less than or equal to 5 mm, it can satisfy that the distance between any two points on the edge of the first mesh hole is less than or equal to 5 mm.

[0067] In some embodiments, the second filter screen 500 has a plurality of second mesh holes. In any one of the second mesh holes, the distance between any two points on the edge of the second mesh hole is less than or equal to 5 mm. Thus, the blocking effect of the second mesh hole on mosquitoes is enhanced, which is beneficial to reducing the probability of mosquitoes entering the compressor cavity 1012, and further beneficial to improving the insect-proof effect on the circuit board 300.

[0068] In some embodiments, such as Figure 2 、 Figure 4As shown, the housing 100 includes a chassis 110 and a top cover 120. The top of the partition member 200 is connected to the top cover 120, and the bottom of the partition member 200 is connected to the chassis 110. The chassis 110 is further provided with a plurality of first grooves 111, and each first groove 111 and the partition member 200 enclose a water passing hole 130.

[0069] In this embodiment, the housing 100 includes a chassis 110 and a top cover 120. It is easy to understand that the housing 100 further includes a plurality of side plates connecting the chassis 110 and the top cover 120. The top of the partition member 200 is connected to the top cover 120, and the bottom of the partition member 200 is connected to the chassis 110. Thus, the fixed installation of the partition member 200 in the accommodation cavity 101 is realized. Since a small amount of condensed water is generated when the outdoor unit 10 is working, the condensed water needs to be discharged through the drain port at the bottom of the blower cavity 1011. Therefore, in this embodiment, the chassis 110 is further provided with a plurality of first grooves 111, and each first groove 111 and the partition member 200 enclose a water passing hole 130. Through the water passing hole 130, the condensed water in the compressor cavity 1012 can be discharged into the blower cavity 1011 and discharged through the drain port in the blower cavity 1011.

[0070] Since the water passing hole 130 generally has a large area, it is easy for external mosquitoes to enter the compressor cavity 1012 through the water passing hole 130. Thus, in some embodiments, as Figures 5 to 8 shown and with reference to Figure 5 , the outdoor unit 10 further includes a plurality of sealing members 900 connected to the partition member 200. Each sealing member 900 is disposed between the first groove 111 and the partition member 200. The sealing member 900 abuts against the first groove 111, and at least one second groove 901 is provided on the surface of the sealing member 900 close to the first groove 111. With such a setting, on the one hand, a part of the sealing member 900 can block the water passing hole 130 to prevent mosquitoes from entering the compressor cavity 1012 through the water passing hole 130. On the other hand, since the sealing member 900 abuts against the first groove 111, the second groove 901 of the sealing member 900 and the first groove 111 of the chassis 110 re-enclose a new small water passing hole (the third mesh hole). The small water passing hole can allow the condensed water to pass through and at the same time has a certain anti-mosquito effect. Thus, it is beneficial to further improve the anti-insect effect on the circuit board 300.

[0071] It is easy to understand that since the second groove 901 and the first groove 111 of the chassis 110 re-enclose a new small water passing hole, without considering the elastic deformation of the sealing member 900, the shape of the surface of the sealing member 900 close to the first groove 111 is substantially the same as the shape of the inner surface of the first groove 111.

[0072] In some embodiments, each second groove 901 and the first groove 111 enclose a third mesh hole. In any third mesh hole, the distance between any two points on the edge of the third mesh hole is less than or equal to 5 mm. With such a setting, the blocking ability of the third mesh hole formed by the second groove 901 of the seal 900 and the first groove 111 of the chassis 110 against mosquitoes is further improved, which is beneficial to further improving the anti-insect effect on the circuit board 300.

[0073] It should be noted that the thickness of the seal 900 is much greater than the thicknesses of the first filter net 400 and the second filter net 500, so that the formed third mesh hole also has a certain thickness. In this way, in the above embodiments, any two points on the edge of the third mesh hole refer to any two points on the edge of the third mesh hole in the cross-section obtained by making a cross-section of the third mesh hole with a plane perpendicular to the thickness direction of the partition 200.

[0074] In some embodiments, such as Figure 7 and Figure 8 As shown, a second flanging 240 is provided at the bottom of the partition 200. The partition 200 is connected to the chassis 110 through the second flanging 240. The seal 900 includes a clamping portion 910, a water passing portion 920, and a water passing portion 930 connecting the clamping portion 910 and the water passing portion 920. The clamping portion 910 is provided with a clamping groove 911. The clamping portion 910 is clamped to the second flanging 240 through the clamping groove 911. The water passing portion 920 abuts against the first groove 111. The second groove 901 is provided on the surface of the water passing portion 920 close to the first groove 111.

[0075] In this embodiment, the partition 200 is connected to the chassis 110 through the second flanging 240, which can improve the convenience of the connection between the two. Further, the seal 900 includes a clamping portion 910, a water passing portion 920, and a blocking portion 930. The clamping portion 910 is clamped to the second flanging 240 through the clamping groove 911, so that the seal 900 can be fixed. After the partition 200 is connected to the chassis 110, the seal 900 is clamped between the first groove 111 and the second flanging 240. The blocking portion 930 of the seal 900 can block most of the area of the water passing hole 130 formed by the first groove 111 of the chassis 110 and the partition 200, and the water passing portion 920 can block the other small part of the area of the water passing hole 130. The second groove 901 of the seal 900 is formed on the surface of the water passing portion 920 close to the first groove 111. In this way, the second groove 901 of the water passing portion 920 and the first groove 111 re-form a third mesh hole for simultaneously playing the roles of water passing and anti-insect. Therefore, it is beneficial to further improve the anti-insect effect on the circuit board 300 while ensuring drainage.

[0076] In some embodiments, Figure 2 and Figure 5As shown, the outdoor unit 10 further includes a blower 700, a first heat exchanger 710, and a compressor 800. The blower 700 and the first heat exchanger 710 are disposed in the blower chamber 1011, and the compressor 800 is disposed in the compressor chamber 1012. Thus, a design of separating the blower 700 and the compressor 800 into different chambers is achieved, and at the same time, the blower 700 can dissipate heat from the first heat exchanger 710. Further, an air outlet (not shown in the figure) opposite to the blower 700 is provided on the housing 100 of the blower chamber 1011. This air outlet is different from the first ventilation opening, and is used for the air agitated by the blower to blow out.

[0077] Further, as Figure 2 and Figure 5 shown, the outdoor unit 10 further includes a second heat exchanger 720, and the second heat exchanger 720 is disposed in the compressor chamber 1012. Since both the first heat exchanger 710 and the second heat exchanger 720 are provided in the housing 100, in this case, the outdoor unit 10 can be regarded as an integrated unit. Thus, it is beneficial to realize the miniaturization of the heating and ventilation equipment.

[0078] In a second aspect, the present application provides a heating and ventilation equipment, including the outdoor unit 10 described in the first aspect. The heating and ventilation equipment can be an air conditioner, a heat pump, etc. In the heating and ventilation equipment according to the embodiments of the present application, the outdoor unit 10 described in the first aspect is used. The outdoor unit 10 directly disposes the circuit board 300 in the compressor chamber 1012 and fixedly connects it to the partition member 200, so that there is no need to additionally provide a circuit box for dissipating heat from and preventing insects from damaging the circuit board 300. In other words, the compressor chamber 1012 serves as the circuit box for the circuit board 300 in the related art. Further, the housing 100 is further provided with a first ventilation opening 102 communicating with the compressor chamber 1012, and the first filter net 400 covers the first ventilation opening 102. The heat of the circuit board 300 can be dissipated to the outside through the first ventilation opening 102, and at the same time, the first filter net 400 can prevent mosquitoes and insects from entering the compressor chamber 1012 through the first ventilation opening 102, so that the compressor chamber 1012 can also complete the work of dissipating heat from and preventing insects from damaging the circuit board 300. In this way, while ensuring the heat dissipation and insect prevention of the circuit board 300, the cost of the whole machine can be reduced, and the assembly process of the whole machine can be simplified.
