[0001] This utility model belongs to the field of air conditioner technology, specifically relating to a sheet metal plate, an outdoor unit, and an air conditioner. Background Technology

[0002] The outer casing of the air conditioner outdoor unit includes a sheet metal plate installed on the outside of the compressor. During the production process, hanging holes need to be reserved on the sheet metal plate so that it can be hung up for spraying anti-corrosion coating. The existing hanging hole placement causes the sheet metal plate to tilt when hung, resulting in poor spraying and ultimately poor anti-corrosion effect, making the sheet metal plate prone to rust. Utility Model Content

[0003] Therefore, this utility model provides a sheet metal plate, an outdoor unit, and an air conditioner, which can solve the technical problems of poor coating and poor anti-corrosion effect of sheet metal plates in the prior art.

[0004] In a first aspect, this utility model provides a sheet metal plate for the outdoor unit of an air conditioner. The outdoor unit includes a housing, and the sheet metal plate forms part of the side panel of the housing. The sheet metal plate includes a hanging hole on its top and a first panel. When the sheet metal plate is lifted through the hanging hole, the angle between the first panel and the vertical plane is not greater than 3°.

[0005] In some embodiments, the sheet metal plate further includes a second panel connected to the first panel, and the included angle between the second panel and the first panel is between 88° and 92°; when the sheet metal plate is lifted through the hanging hole, the included angle between the second panel and the vertical plane is not greater than 3°.

[0006] In some embodiments, in the horizontal direction, the length of the first panel is greater than the length of the second panel, and the top of the first panel is bent toward the inside of the outdoor unit to form a baffle, and the hanging hole is provided on the baffle.

[0007] In some embodiments, the sheet metal plate is provided with a fastener, the fastener is disposed on the outside of the housing, the fastener is integrally formed with the sheet metal plate, and the fastener is used to fix the temperature sensing bulb.

[0008] In some embodiments, the fastener includes a first snap-fit ​​portion and a second snap-fit ​​portion and a third snap-fit ​​portion disposed at both ends of the first snap-fit ​​portion.

[0009] In some embodiments, the first snap-fit ​​portion includes a first groove, the second snap-fit ​​portion includes a second groove, and the third snap-fit ​​portion includes a third groove. The opening of the first groove faces a first direction, and the openings of the second and third grooves both face a second direction, wherein the first direction and the second direction are opposite.

[0010] In some embodiments, the temperature sensing element is cylindrical, and along the length direction of the first groove, the distance between the second groove and the first groove is greater than the diameter of the temperature sensing element, and the distance between the third groove and the first groove is greater than the diameter of the temperature sensing element.

[0011] In some embodiments, when a second panel is provided, the fastener is disposed on the second panel, a control board is disposed on the side of the second panel facing the interior of the outdoor unit, and a wire hole is provided on the second panel.

[0012] This utility model also provides an outdoor unit, which includes the aforementioned sheet metal plate.

[0013] In some embodiments, the first panel is provided with a baffle, the housing includes a top cover, and the top cover has a side plate extending downward on one side adjacent to the first panel. The top cover covers the baffle and the side plate covers the upper outer side of the first panel.

[0014] This utility model also provides an air conditioner, including the aforementioned outdoor unit.

[0015] This invention repositions the hanging holes, ensuring that the first panel of the sheet metal remains essentially vertical when suspended through them. This allows for more even coating during spraying, thereby improving the sheet metal's corrosion resistance.

[0016] This application also designs the fixing parts of the temperature sensing bag so that the fixing parts are integrally formed with the sheet metal plate. On the one hand, this reduces the number of parts, and on the other hand, it improves the structural strength of fixing the temperature sensing bag, ensuring the stability and accuracy of temperature detection.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0033] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0034] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0035] See also Figure 1-9 As shown, this utility model provides a sheet metal plate for the outdoor unit of an air conditioner. The outdoor unit includes a housing, and the sheet metal plate 1 forms part of the side panel of the housing. The sheet metal plate 1 includes a hanging hole 501 on its top and a first panel 101. When the sheet metal plate 1 is lifted through the hanging hole 501, the angle between the first panel 101 and the vertical plane is not greater than 3°.

[0036] By ensuring that the angle between the first panel 101 and the vertical plane is no greater than 3°, when the first panel 101 is sprayed, the paint can adhere more evenly to the surface of the first panel 101, thereby improving the corrosion resistance of the first panel 101.

[0037] The value of 3° can be determined based on the actual production process and corrosion protection requirements. Preferably, such as... Figure 1-3As shown, the sheet metal plate 1 also includes a second panel 102, which is connected to the first panel 101. The included angle between the second panel 102 and the first panel 101 is between 88° and 92°. When the sheet metal plate 1 is lifted by the hanging hole 501, the included angle between the second panel 102 and the vertical plane is not greater than 3°.

[0038] The angle between the second panel 102 and the first panel 101 is between 88° and 92°, meaning that the second panel 102 and the first panel 101 are basically perpendicular. The second panel 102 and the first panel 101 cover the outdoor unit as a whole. When lifted through the hanging hole 501, the angle between the second panel 102 and the vertical plane is no greater than 3°, which allows the surface of the second panel 102 to be coated with anti-corrosion material more evenly during the spraying of the sheet metal plate 1, thus improving the anti-corrosion capability of the second panel 102.

[0039] Preferred, such as Figure 1-3 As shown, in the horizontal direction, the length of the first panel 101 is greater than the length of the second panel 102. The top of the first panel 101 is bent toward the inside of the outdoor unit to form a baffle 502, and the hanging hole 501 is provided on the baffle 502.

[0040] In this application, the term "horizontal" refers to the horizontal direction when the outdoor unit is in operation. "Horizontal" does not impose any restrictions on the specific structure; it is a positioning used to facilitate the description of the spatial structure. Similarly, "top" refers to the top of the outdoor unit when it is in operation.

[0041] Since the length of the first panel 101 is greater than the length of the second panel 102, by setting a baffle 502 with the top of the first panel 101 facing the inside of the outdoor unit and setting the hanging hole 501 on the baffle 502, on the one hand, it is convenient to hoist the sheet metal plate 1; on the other hand, when a cover plate is set on it and covers the hanging hole 501, the sealing performance of the outdoor unit is improved.

[0042] like Figure 6 and Figure 7 As shown, the position of the hanging hole 501 is determined as follows: the hanging hole 501 is located in a preset plane, wherein the plane where the first panel 101 is located intersects the plane where the second panel 102 is located at a straight line L. The preset plane passes through the center of gravity of the sheet metal plate 1, is parallel to the straight line L, and is perpendicular to the first panel 101.

[0043] Furthermore, the hanging hole 501 is a circular hole with a diameter of 6mm-8mm.

[0044] Preferred, such as Figure 1-3As shown, the sheet metal plate 1 is provided with a fastener 503, which is located on the outside of the outer shell. The fastener 503 is integrally formed with the sheet metal plate 1 and is used to fix the temperature sensing bulb 6.

[0045] In existing technology, the outdoor unit of an air conditioner senses the temperature of the outside air through a temperature sensor 6, which is typically installed on the air intake side of the outdoor unit. The temperature sensor 6 is usually fixed to a bracket, such as... Figure 10 As shown, it is then clipped onto the copper pipes of the condenser of the outdoor unit. This method requires many additional mounting brackets, is inefficient, and is prone to loosening and falling off during transportation, resulting in low stability. Moreover, it may damage the condenser fins and copper pipes. If the clip is not secure, the temperature sensor 6 may also fall off, leading to inaccurate temperature detection and affecting the use of the air conditioner.

[0046] This application reduces the number of parts, improves the fixing firmness of the fixing part 503, and also improves production efficiency by integrally molding the fixing part 503 of the fixing temperature sensing bulb 6 with the sheet metal plate 1 (the fixing part 503 and the sheet metal plate 1 are formed from the same plate).

[0047] Preferred, such as Figure 1-3 As shown, the fastener 503 includes a first snap-fit ​​portion 201 and a second snap-fit ​​portion 202 and a third snap-fit ​​portion 203 disposed at both ends of the first snap-fit ​​portion 201.

[0048] By setting the three locking parts mentioned above, the secure fixation of the temperature sensing bag 6 is improved.

[0049] Furthermore, the sheet metal plate 1 has a thin-walled structure and a certain elastic deformation capability, which enables it to elastically wrap and compress the temperature sensing bulb 6.

[0050] Preferred, such as Figure 1-3 As shown, the first snap-fit ​​portion 201 includes a first groove, the second snap-fit ​​portion 202 includes a second groove, and the third snap-fit ​​portion 203 includes a third groove. The opening of the first groove faces a first direction, and the openings of the second and third grooves both face a second direction. The first direction and the second direction are opposite.

[0051] With the above-described arrangement, the temperature sensor 6 is fixed within the groove, improving the stability of the fixation of the temperature sensor 6. Figure 2 As shown, the middle part of the temperature sensing bag 6 is wrapped by the first groove, which mainly applies a force in the first direction to the temperature sensing bag 6. The two ends of the temperature sensing bag 6 are wrapped by the second groove and the third groove, which mainly apply a force in the second direction to the temperature sensing bag 6. Since the first direction and the second direction are opposite, the temperature sensing bag 6 is wrapped and squeezed, thus fixing the temperature sensing bag 6 firmly.

[0052] Preferably, the temperature sensing element 6 is cylindrical, and in the length direction of the first groove, the distance between the second groove and the first groove is greater than the diameter of the temperature sensing element 6, and the distance between the third groove and the first groove is greater than the diameter of the temperature sensing element 6.

[0053] The temperature sensing bag 6 is cylindrical. Since the distance between the second groove and the first groove is greater than the diameter of the temperature sensing bag 6, and the distance between the third groove and the first groove is greater than the diameter of the temperature sensing bag 6, when fixing the temperature sensing bag 6, the temperature sensing bag 6 is inserted between the first groove and the second groove, and then the temperature sensing bag 6 is rotated so that the middle part of the temperature sensing bag 6 enters the first groove and one end enters the second groove; then the third groove is deformed, so that the other end of the temperature sensing bag 6 is first inserted between the first groove and the third groove, and the third groove is restored so that the third groove acts on the temperature sensing bag 6, thereby fixing the temperature sensing bag 6.

[0054] Furthermore, the sheet metal plate 1 has a certain elastic deformation capacity, so the fastener 503 also has a certain elastic deformation capacity, which can achieve better fixation of the temperature sensing bulb 6.

[0055] Preferred, such as Figure 4-5 As shown, when the second panel 102 is provided, the fixing member 503 is provided on the second panel 102, and a control board is provided on the side of the second panel 102 facing the interior of the outdoor unit. The second panel 102 is provided with a wire hole 504.

[0056] By providing a wire hole 504 on the second panel 102, a temperature sensor 6 is fixedly installed on one side of the second panel 102, and a control board is installed on the other side. The temperature sensor 6 and the control board are connected by a wire, which passes through the wire hole 504 and through the second panel 102. In this way, the length of the wire is shortened, which helps to reduce the risk of the wire being too long (for example, the wire being dragged and pulling the temperature sensor 6 out of the fixing member 503).

[0057] Specifically, the wire hole 504 is located on the upper edge of the second panel 102 and is U-shaped.

[0058] Specifically, such as Figure 3As shown, a fixing member 503 for fixing the temperature sensor 6 is provided 30-40mm below the wire hole 504, which facilitates wiring. A first support wall is provided vertically outward from the outer edge of the second panel 102. The angle between the first support wall and the second panel 102 is between 90° and 135° (90° is preferred). Its vertical length is 50-60mm, and its height (the height perpendicular to the second panel 102) is 15-20mm. To ensure structural strength, several first reinforcing ribs 401 are provided at the connection between the first support wall and the second panel 102. Furthermore, a second support arm 302 is provided at the top of the first support wall. The second support arm 302 is parallel to the second panel 102. To improve strength, several second reinforcing ribs 402 are provided at the junction of the second support arm 302 and the first support wall (corner connection). A U-shaped first groove is provided 10-15mm outward from the middle of the second support arm 302 (away from the first support arm 301) to accommodate the temperature sensor 6. To avoid scratching the temperature sensor 6 during installation, a first rounded corner 701 is provided at the corner of the outer baffle wall. The radius of the first rounded corner 701 is not less than 3mm. If the wire diameter of the temperature sensor 6 is D, then the depth of the first groove is D and the width is D+0.5mm. The distance between the bottom of the first groove and the condenser fins is not less than 8mm to avoid interference from the condenser temperature on the detection of the temperature sensor 6. Furthermore, L-shaped baffles are provided at both ends of the upper and lower edges of the first support arm 301. The L-shaped baffles are spaced apart from the first groove. The openings of the L-shaped baffles (the space surrounded by the L-shaped baffles forms the second and third grooves) face inwards, opposite to the opening direction of the first groove. The three grooves (the first, second, and third grooves) cooperate to fix the temperature sensor 6. In addition, the width of the L-shaped baffles is not less than 6mm. To prevent scratches on the temperature sensor 6 during assembly, a folded edge is provided on the edge of the L-shaped baffles, and a second rounded corner 702 is provided at the corner, which is not less than 3mm. Furthermore, the gap width between the first and second grooves is (0.5-1)mm larger than the wire diameter D of the temperature sensor 65, which facilitates the sliding of the temperature sensor 6 from between the first and second grooves into the L-shaped baffles and the groove.

[0059] This utility model also provides an outdoor unit, wherein the sheet metal plate 1 of the outdoor unit is provided.

[0060] Preferred, such as Figure 8-9 As shown, the first panel 101 is provided with a baffle 502, and the outer shell includes a top cover 505. The top cover 505 is provided with a side plate 506 extending downward on the side adjacent to the first panel 101. The top cover 505 covers the baffle 502 and the side plate 506 covers the upper outer side of the first panel 101.

[0061] like Figure 11As shown, in the existing technology, the hanging holes are located on the side wall. When the outdoor environment is harsh, rainwater, sand and dust may enter the interior of the outdoor unit through the gaps between the sheet metal parts of the outer casing and the hanging holes, thereby damaging the internal components.

[0062] like Figure 8 and Figure 9 As shown, this application includes a baffle 502 on the first panel 101 and a top cover 505 on the outer casing. A side plate 506 extending downwards is provided on the side of the top cover 505 adjacent to the first panel 101. The top cover 505 covers the baffle 502, and the side plate 506 covers the upper outer side of the first panel 101. When the top cover 505 covers the sheet metal plate 1, it not only covers the baffle 502, but the side plate 506 of the top cover 505 also partially overlaps with the top of the sheet metal plate 1. This makes it difficult for external wind, water, and dust to enter the outdoor unit through the hanging holes 501 on the baffle 502, preventing corrosion and damage to the internal components of the outdoor unit and improving its safety.

[0063] This utility model also provides an air conditioner, including the aforementioned outdoor unit.

[0064] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0065] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
