Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an evaporator support bracket, an indoor air conditioner unit, and an air conditioner. Background Technology

[0002] Typically, for indoor units of cabinet air conditioners, the brackets supporting the evaporator are divided into upper brackets, lower brackets, and intermediate brackets. The upper bracket primarily supports the motor bracket within the air duct, making its rigidity and strength particularly important. However, existing upper brackets have poor rigidity and strength, making it difficult to effectively suppress vibrations during motor operation and failing to provide effective support for the motor. Furthermore, to accommodate wiring, a recessed notch is provided on the flat section of the upper bracket near the motor bracket; however, this notch compromises the structural integrity of the upper bracket and reduces its strength. Summary of the Invention

[0003] The first objective of this invention is to provide an evaporator upper bracket to solve the technical problem of insufficient rigidity of existing air conditioner indoor unit evaporator upper brackets.

[0004] The evaporator upper support provided by the present invention includes a support plate, the support plate being configured to surround a motor support, and the support plate having a protrusion extending along the height direction of the support plate.

[0005] The beneficial effects of the evaporator support bracket of this invention are:

[0006] By setting protrusions on the support plate, the side walls of the protrusions can form ribs relative to the support plate, thereby improving the load-bearing capacity of the support plate, increasing the rigidity of the support on the evaporator, and improving the support effect on the motor support.

[0007] In a preferred embodiment, the protrusion is located on the side of the bracket plate facing the motor bracket.

[0008] Since the motor bracket is located on the inner side of the bracket plate, the inner side of the bracket plate is subjected to greater force. By setting the protrusion on the side of the bracket plate facing the motor bracket, the rigidity of this part of the bracket plate can be significantly increased, thereby improving the support for the motor bracket.

[0009] In a preferred embodiment, the protrusion is provided with an extended ridge, which extends toward the opening of the support plate.

[0010] By providing an extended ridge to the protrusion, the rigidity of the protrusion at its midpoint along its length can be increased. Furthermore, it allows the portion of the connecting plate used to mount the PTC auxiliary heating element to remain unchanged without altering the dimensions of other components. In particular, the rigidity of the protrusion is reduced when a notch is created in the middle; providing an extended ridge increases the rigidity of the protrusion, at least partially compensating for the loss of rigidity.

[0011] In a preferred embodiment, the support plate is U-shaped, comprising a first arm and a second arm arranged at an angle, and a connecting plate portion connecting the first arm and the second arm; the protrusion includes a first convex ridge, a second convex ridge, and an arc-shaped convex ridge; the first arm and the second arm are respectively the two arms of the U-shape; the first arm is provided with the first convex ridge, the second arm is provided with the second convex ridge, and the connecting plate portion is provided with the arc-shaped convex ridge; the first convex ridge and the second convex ridge are located on the same side of the first arm and the second arm, and the arc-shaped convex ridge connects the first convex ridge and the second convex ridge.

[0012] The evaporator support also includes a surrounding plate, which is connected to the side of the support plate facing the motor support by a chamfer. The surrounding plate includes a first surrounding plate, and the chamfer includes a first chamfer. The first surrounding plate is connected to the first arm and the connecting plate through the first chamfer. The chamfer radius of the first chamfer gradually decreases from the middle position in the length direction to both ends.

[0013] By providing a first protruding rib on the first arm, a second protruding rib on the second arm, and an arc-shaped protruding rib on the connecting plate, the rigidity of the evaporator support can be improved by the participation of ribs along at least most of the length in the U-shaped extension direction. This strengthens the rigidity of the support plate in its entire extension direction, which is beneficial to improving the rigidity of the evaporator support.

[0014] By incorporating a surrounding plate, the surrounding plate can be used as a rib on the edge of the support plate facing the opening direction, significantly improving the rigidity of the support plate on that side. Furthermore, by connecting the first surrounding plate and the protrusion with a first chamfered section, and maximizing the chamfer radius, shrinkage during injection molding is reduced, improving the integrity of the support plate's surface shape, minimizing wrinkles, and thus ensuring strength. However, due to the limitations of the overall air conditioner structure, other mounting structures are required at the ends of the first protruding ridge, which are relatively close to the edge of the first protruding ridge facing the motor bracket. Therefore, the first chamfered section is designed with a gradually decreasing chamfer radius from the middle of its length towards both ends. This balances the conflict between the placement of the mounting structures and increased strength, thereby maximizing the strength of the evaporator support.

[0015] In a preferred embodiment, the enclosure plate is provided with a supporting protrusion, which is located on one side of the enclosure plate away from the support plate and is configured to contact the motor support.

[0016] By setting a support ridge on the side of the enclosure away from the support plate, the evaporator support can contact the motor support only through the support ridge, reducing the area of ​​possible contact and improving the machining accuracy of this small area of ​​the support ridge. This allows the support ridge to reliably contact the motor support along the entire length of the support ridge, thus enabling the motor support to be supported by the evaporator support in multiple directions.

[0017] In a preferred embodiment, the evaporator support also includes a surrounding plate, which is connected to the side of the support plate facing the motor support; the connecting plate has a wire-passing notch, and the edge of the wire-passing notch has a wire-passing surrounding plate, the two ends of the wire-passing surrounding plate in the length direction are respectively connected to the surrounding plate.

[0018] By incorporating cable passage notches, cables can be accommodated, preventing them from being damaged by being clamped by the motor bracket and evaporator support. While these notches don't cause significant stress concentration, they do reduce the rigidity and strength of the support plate. Cable passage baffles, on the other hand, act as reinforcing ribs, increasing the rigidity and strength of the support plate and compensating for this loss. Furthermore, the cable passage baffles ensure that the cable contacts the baffle at the notch, rather than the protruding part of the plate, thus increasing the contact area and preventing the cable from being cut or abraded by the side edges of the support plate. This also reduces the bending of the cable at the support plate, ultimately extending its lifespan.

[0019] In a preferred embodiment, the enclosure portion is interrupted at the wire passage gap, and at least one of the enclosure portions on both sides of the wire passage gap protrudes from the wire passage enclosure.

[0020] By making at least one of the side panels at the cable passage gap protrude beyond the cable passage enclosure, the protruding portion can be used to prevent the cable from detaching from the cable passage gap, thus preventing the outer surface of the cable from contacting the high-temperature and high-hardness surface of the motor bracket during operation. This reduces the speed and possibility of damage to the cable insulation layer and improves the reliability of the cable.

[0021] In a preferred embodiment, the wire guide plate is lower than the guard plate portion.

[0022] Since the cable needs to connect to related electrical or electronic components after passing through the bracket plate, setting the cable guide plate lower than the main body of the bracket plate allows the cable to bend at a lower position, thus avoiding the problem of excessive cable bend angle caused by excessively high bending position, and ensuring the cable life.

[0023] The second objective of this invention is to provide an indoor air conditioning unit to solve the technical problem of insufficient rigidity of the bracket on the evaporator of the indoor air conditioning unit.

[0024] The air conditioner indoor unit provided by the present invention includes the above-mentioned evaporator upper bracket.

[0025] By installing the aforementioned evaporator bracket in the indoor unit of the air conditioner, the indoor unit of the air conditioner accordingly possesses all the advantages of the aforementioned evaporator bracket, which will not be elaborated here.

[0026] The third objective of this invention is to provide an air conditioner that solves the technical problem of insufficient rigidity of the bracket on the evaporator of the indoor unit of an air conditioner.

[0027] The air conditioner provided by the present invention includes the above-mentioned indoor air conditioner unit.

[0028] By installing the aforementioned air conditioning indoor unit in the air conditioning indoor unit, the air conditioner accordingly possesses all the advantages of the air conditioning indoor unit bracket, which will not be elaborated here. Attached Figure Description

Detailed Implementation

[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0036] Example 1:

[0037] Figure 1 This is a schematic diagram of the evaporator support structure as viewed from a slightly lower angle, according to an embodiment of the present invention. Figure 1 As shown, the evaporator upper support provided in this embodiment includes a support plate 10, which is configured to surround the motor support (not shown in the figure), and the support plate 10 is provided with a protrusion that protrudes along the height direction of the support plate 10.

[0038] In order to reduce or even eliminate the shrinkage effect during the injection molding process, the protrusion is chamfered at the joint with the bracket plate 10.

[0039] By providing a protrusion in the support plate 10, the side wall of the protrusion can be used to form a rib relative to the support plate 10, thereby improving the load-bearing capacity of the support plate 10, and thus improving the rigidity of the support on the evaporator and improving the support effect on the motor support.

[0040] like Figure 1 As shown, preferably, the protrusion is provided on the side of the bracket plate 10 facing the motor bracket.

[0041] Since the motor bracket is located on the inner side of the bracket plate 10, the inner side of the bracket plate 10 is subjected to greater force. By setting the protrusion on the side of the bracket plate 10 facing the motor bracket, the rigidity of this part of the bracket plate 10 can be significantly increased, thereby improving the support of the motor bracket.

[0042] Figure 2 This is a schematic diagram of the evaporator support provided in an embodiment of the present invention, viewed from another direction; as shown. Figure 1 and Figure 2 As shown, preferably, the protrusion is provided with an extended ridge 24, which extends in the direction of the opening of the support plate 10.

[0043] By providing an extended ridge 24 to the protrusion, the rigidity of the protrusion at its midpoint along the length direction can be increased. Furthermore, it allows the portion of the connecting plate 10 used to mount the PTC auxiliary heating element to remain unchanged without altering the dimensions of other components. In particular, the rigidity of the protrusion is reduced after the wire-passing notch 41 is opened at its midpoint; providing the extended ridge 24 increases the rigidity of the connecting plate 12, at least partially compensating for the loss of rigidity.

[0044] Figure 3 This is a schematic diagram of the evaporator support provided in an embodiment of the present invention, viewed from another direction. (See diagram below.) Figures 1-3 As shown, preferably, the support plate 10 is U-shaped, and includes a first arm 11 and a second arm 13 arranged at an angle, and a connecting plate portion 12 connecting the first arm 11 and the second arm 13; the protrusion includes a first convex ridge portion 21, a second convex ridge portion 23, and an arc-shaped convex ridge portion 22; the first arm 11 and the second arm 13 are respectively the two arms of the U-shape; the first arm 11 is provided with the first convex ridge portion 21, the second arm 13 is provided with the second convex ridge portion 23, and the connecting plate portion 12 is provided with the arc-shaped convex ridge portion 22; the first convex ridge portion 21 and the second convex ridge portion 23 are located at... On the same side of the first arm 11 and the second arm 13, the arc-shaped protrusion 22 connects the first protrusion 21 and the second protrusion 23; the upper support of the evaporator also includes a surrounding plate 30, which is connected to the side of the support plate 10 facing the motor support through a chamfer; the surrounding plate 30 includes a first surrounding plate 31, and the chamfer includes a first chamfer 33. The first surrounding plate 31 is connected to the first arm 11 and the connecting plate 12 through the first chamfer 33; the chamfer radius of the first chamfer 33 gradually decreases from the middle position in the length direction to both ends.

[0045] The first protruding ridge 21 does not extend entirely along the length of the first arm 11. Specifically, it can be inclined relative to the length of the first arm 11. That is, one end of the first protruding ridge 21 is connected to one end of the arc-shaped protruding ridge 22, and the other end extends to the inner side of the first arm 11.

[0046] Specifically, the cross-sections perpendicular to their respective length directions of the first protruding ridge 21, the second protruding ridge 23, the arc-shaped protruding ridge 22, and the extended protruding ridge 24 described below can be rectangular or trapezoidal, and further, can be right-angled trapezoids or isosceles trapezoids. The hypotenuse of the right-angled trapezoid is the part connecting the protrusion and the support plate 10. The angled portions of the aforementioned shapes can also be chamfered. The thickness of the support plate 10 and the protrusion can be approximately the same, without significantly increasing the material thickness due to the protrusion. Thus, greater rigidity can be achieved using less material.

[0047] In addition to the first enclosure plate portion 31 mentioned above, the enclosure plate portion 30 also includes a second enclosure plate portion 32 connected to the second arm 13. The second enclosure plate portion 32 is connected to the second arm 13 and the connecting plate portion 12 through a second chamfer portion 34. Figure 1 As can be seen, the chamfer radius of the second chamfer 34 is approximately the same at various positions along its length. Similarly, in... Figure 1 As can be seen, even though the different positions of the peeling arcs lead to different projection angles and changes in visual effect, it is clear that the width of the middle part of the first chamfer 33 in the length direction is greater than that of the two ends. The result is that the chamfer radius is larger in the middle and smaller at the two ends.

[0048] By providing a first protruding rib 21 in the first arm 11, a second protruding rib 23 in the second arm 13, and an arc-shaped protruding rib 22 in the connecting plate 12, the rigidity of the support plate 10 can be improved by the participation of ribs along at least most of its length in the U-shaped extension direction. This strengthens the rigidity of the support plate 10 throughout its entire extension direction, which is beneficial for improving the rigidity of the support on the evaporator. By providing a surrounding plate 30, the surrounding plate 30 can be used as a rib on the edge of the support plate 10 facing the opening direction, significantly improving the rigidity of the support plate 10 on the opening direction side. Furthermore, by providing a first chamfered portion connecting the first surrounding plate 31 and the protrusion, and maximizing the chamfer radius, shrinkage of the material during injection molding can be reduced, improving the integrity of the surface shape of the support plate 10, reducing wrinkles, and thus ensuring strength. However, other mounting structures need to be installed at the two ends of the first protruding ridge 21. The distance between the first protruding ridge 21 and the edge facing the motor bracket is small. Therefore, the first chamfer 33 is set so that the chamfer radius gradually decreases from the middle position in the length direction to both ends. This can balance the contradiction between the position of the mounting structure and the improvement of strength, thereby ensuring the strength of the bracket on the evaporator as much as possible.

[0049] like Figures 1-3 As shown, preferably, the surrounding plate portion 30 is provided with a supporting protrusion 35, which is disposed on the side of the surrounding plate portion 30 opposite to the support plate 10, and is configured to contact the motor bracket. Specifically, the supporting protrusion 35 can be disposed at the middle position in the height direction of the surrounding plate portion 30 and parallel to the support plate 10. The cross-section of the supporting protrusion 35 perpendicular to the length direction is a chamfered rectangle or a chamfered isosceles trapezoid.

[0050] By providing a support ridge 35 on the side of the enclosure 30 away from the support plate 10, the evaporator upper support can contact the motor support only through the support ridge 35, reducing the area of ​​possible contact and improving the machining accuracy of this small area of ​​the support ridge 35. This allows the support ridge 35 to reliably contact the motor support in its entire length direction, thereby enabling the motor support to be supported by the evaporator upper support in multiple directions.

[0051] like Figures 1-3 As shown, preferably, the connecting plate portion 12 is provided with a wire passage notch 41, and the edge of the wire passage notch 41 is provided with a wire passage enclosure 42. The two ends of the wire passage enclosure 42 in the length direction are respectively connected to the enclosure portion 30.

[0052] By providing a cable passage notch 41, cables can be accommodated, preventing them from being damaged by being clamped by the motor bracket and the evaporator bracket. While the notch 41 does not cause significant stress concentration, it reduces the rigidity and strength of the bracket plate 10. The cable passage enclosure 42 acts as a reinforcing rib, increasing the rigidity and strength of the bracket plate 10 and compensating for the loss of rigidity and strength. Furthermore, the cable passage enclosure 42 ensures that the cable contacts the enclosure 42 at the notch 41, rather than directly on the bracket plate 10. This increases the contact area, preventing the cable from being cut or abraded by the side edges of the bracket plate 10, reducing the bending degree of the cable at the bracket plate 10, and thus improving the cable's service life.

[0053] like Figures 2-3 As shown, preferably, the enclosure portion 30 is interrupted at the wire passage gap 41, and at least one of the enclosure portions 30 on both sides of the wire passage gap 41 protrudes from the wire passage enclosure 42.

[0054] In this embodiment, the protruding portion may be provided only on one of the surrounding plate portions 30 located on both sides of the wire passage gap 41, for example, at the end of the first surrounding plate portion 31, while the second surrounding plate portion 32 does not protrude from the wire passage surrounding plate 42. In another implementation, it may also be provided on the surrounding plate portions 30 on both sides of the wire passage gap 41. Furthermore, as... Figure 2 As shown, the protruding part can be in the shape of an isosceles trapezoid.

[0055] By making at least one of the side panels 30 on both sides of the cable passage gap 41 protrude beyond the cable passage enclosure 42, the protruding portion can be used to prevent the cable from detaching from the cable passage gap 41, thus preventing the outer surface of the cable from contacting the surface of the motor bracket, which is hot and hard during operation. This reduces the speed and possibility of damage to the cable insulation layer and improves the reliability of the cable.

[0056] like Figures 2-3As shown, preferably, the guide plate 42 is lower than the guide plate portion 30. More specifically, it can be lower than the position of the supporting protrusion 35.

[0057] Since the cable needs to be connected to relevant electrical or electronic components after passing through the bracket plate 10, the cable guide plate 42 is set lower than the guide plate part 30. This allows the cable to be bent at a lower position, thus avoiding the problem of excessive cable bend angle caused by excessively high bend position, and ensuring the cable life.
