Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a chassis, an air conditioning outdoor unit and an air conditioner. Background Art

[0002] The condenser of the air conditioner outdoor unit is installed on the chassis. During the operation of the condenser, condensed water will be discharged. The condensed water can be discharged from the chassis through the drainage structure on the chassis. However, in the prior art, in order to meet the drainage requirements of the condenser, the overall size of the chassis is large and occupies a large amount of space. Summary of the invention

[0003] The problem solved by the present invention is how to reduce the occupied space of the chassis while meeting the drainage requirements of the condenser.

[0004] In order to solve the above problems, the present invention provides a chassis, an air conditioner outdoor unit and an air conditioner, which can effectively improve the above-mentioned technical problems.

[0005] The present invention can be implemented like this:

[0006] An embodiment of the present invention provides a chassis, including a bottom wall, a blocking wall and a protrusion, wherein the bottom wall is provided with an installation area for installing a condenser, the blocking wall is connected to the bottom wall, the protrusion is connected to the blocking wall, the protrusion protrudes relative to the blocking wall in a direction away from the installation area, and a water receiving groove is defined on a side of the protrusion close to the installation area, and the water receiving groove is used to receive condensed water dripping from the condenser.

[0007] In this way, the water receiving groove can receive the condensed water dripping from the condenser to prevent the condensed water from dripping outside the chassis. In addition, since the water receiving groove has met the drainage requirements of the condenser, it is not easy to reserve a gap between the barrier wall and the condenser, so the distance between the barrier wall and the condenser can be correspondingly reduced, thereby shortening the length of the bottom wall, thereby reducing the overall space occupied by the chassis.

[0008] Optionally, a bottom side of the protrusion is located above a bottom side of the barrier wall.

[0009] In this way, the protrusion will not contact the ground and will not occupy any floor space, thereby reducing the overall floor space of the chassis and effectively saving space.

[0010] Optionally, a guiding slope is provided in the water receiving groove, and the guiding slope is used to guide the condensed water in the water receiving groove to flow toward the bottom wall in a direction close to the installation area.

[0011] In this way, the guiding slope can improve the drainage efficiency of the condensed water.

[0012] Optionally, the blocking wall includes a first connecting wall, a second connecting wall and a third connecting wall connected in sequence, the top side of the second connecting wall is lower than the top side of the first connecting wall, the top side of the second connecting wall is lower than the top side of the third connecting wall, and the area between the first connecting wall, the second connecting wall and the third connecting wall forms an installation gap, the protrusion is installed in the installation gap, and the protrusion is simultaneously connected to the first connecting wall, the second connecting wall and the third connecting wall.

[0013] In this way, compared with the situation where the protrusion is connected to only one or two of the connecting walls, the connection stability of the protrusion can be improved and the protrusion is not likely to be detached.

[0014] Optionally, the protrusion and the first connecting wall are transitioned through an arc surface; and / or, the protrusion and the second connecting wall are transitioned through an arc surface; and / or, the protrusion and the third connecting wall are transitioned through an arc surface.

[0015] In this way, the stress between the protrusion and the first connecting wall, between the protrusion and the second connecting wall, and between the protrusion and the third connecting wall can be reduced, and stress concentration between the protrusion and the first connecting wall, between the protrusion and the second connecting wall, and between the protrusion and the third connecting wall can be avoided, thereby extending the service life of the protrusion, the first connecting wall, the second connecting wall, and the third connecting wall.

[0016] Optionally, the protrusion includes a first transition wall, a protruding wall, a second transition wall and a receiving wall, the first transition wall, the protruding wall and the second transition wall are connected in sequence, the side of the first transition wall away from the protruding wall is connected to the side of the first connecting wall close to the installation notch, the side of the second transition wall away from the protruding wall is connected to the side of the third connecting wall close to the installation notch, and the receiving wall is simultaneously connected to the bottom side of the first transition wall, the bottom side of the protruding wall, the bottom side of the second transition wall and the top side of the second connecting wall, wherein the area between the first transition wall, the protruding wall, the second transition wall and the receiving wall forms the water receiving trough.

[0017] In this way, the first transition wall, the protruding wall, the second transition wall and the receiving wall can all play the role of receiving condensed water. Under the joint blocking effect of the first transition wall, the protruding wall, the second transition wall and the receiving wall, the condensed water dripping into the water receiving trough is not easy to splash out of the water receiving trough.

[0018] Optionally, the first transition wall and the protruding wall are arranged at an obtuse angle; and / or, the first transition wall and the first connecting wall are arranged at an obtuse angle; and / or, the second transition wall and the protruding wall are arranged at an obtuse angle; and / or, the second transition wall and the third connecting wall are arranged at an obtuse angle.

[0019] In this way, after stamping, the stamping die can be demoulded more conveniently, thereby improving production efficiency.

[0020] Optionally, the first transition wall and the protruding wall are transitioned through an arc surface; and / or, the second transition wall and the protruding wall are transitioned through an arc surface; and / or, the receiving wall and the protruding wall are transitioned through an arc surface.

[0021] In this way, the stress between the protruding wall and the first transition wall, between the protruding wall and the second transition wall, and between the protruding wall and the receiving wall can be reduced, avoiding stress concentration between the protruding wall and the first transition wall, between the protruding wall and the second transition wall, and between the protruding wall and the third protruding wall, thereby extending the service life of the protruding wall, the first transition wall, the second transition wall and the receiving wall.

[0022] Optionally, a height of the protrusion relative to the outer surface of the barrier wall is A, 3mm≤A≤7mm.

[0023] In this way, it can ensure that the space occupied by the protrusion is small, and at the same time it can prevent the condensed water dripping into the water receiving trough from overflowing, thereby meeting the drainage requirements of the condenser.

[0024] Optionally, the distance between the top and bottom ends of the protrusion in the height direction of the blocking wall is B, and 10mm≤B≤15mm.

[0025] In this way, it is possible to avoid the bottom end of the protrusion from colliding with the ground, thereby extending the service life of the protrusion, while also ensuring that the water receiving groove defined by the protrusion plays its due role in receiving condensed water and meets the drainage requirements of the condenser.

[0026] The embodiment of the present invention further provides an air conditioner outdoor unit, which includes the aforementioned chassis and has all the functions of the chassis. The air conditioner outdoor unit not only meets the drainage requirements of the condenser, but also effectively reduces the space occupied.

[0027] The embodiment of the present invention further provides an air conditioner, which includes the aforementioned air conditioner outdoor unit and has all the functions of the air conditioner outdoor unit. The air conditioner not only meets the drainage requirements of the condenser, but also effectively reduces the space occupied. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] Figure 1 This is a schematic structural diagram of the chassis 1 provided in this embodiment at a first viewing angle. Figure 2 for Figure 1 The enlarged diagram of point C in the middle. Please refer to Figure 1 and Figure 2 The present embodiment provides an air conditioner outdoor unit, which includes a chassis 1 and a condenser (not shown in the figure). The chassis 1 includes a bottom wall 11, and a mounting area 111 is provided on the bottom wall 11. The condenser is connected to the bottom wall 11, and the condenser is located in the mounting area 111. During operation, the condenser will discharge condensed water, which will drip onto the bottom wall 11 and be discharged from the air conditioner outdoor unit through the drainage structure on the bottom wall 11.

[0037] Please refer to Figure 1 and Figure 2 In this embodiment, the chassis 1 further includes a blocking wall 12, which is connected to the bottom wall 11. The blocking wall 12 can prevent the condensed water on the bottom wall 11 from flowing out of the bottom wall 11, thereby preventing the condensed water on the bottom wall 11 from flowing onto the ground. In this embodiment, the chassis 1 further includes a protrusion 13, which is connected to the blocking wall 12. The protrusion 13 protrudes relative to the blocking wall 12 in a direction away from the installation area 111, and a water receiving groove 14 is defined on a side of the protrusion 13 close to the installation area 111.

[0038] It should be noted that, in this embodiment, the position of the water receiving groove 14 corresponds to the position of the condenser. The water receiving groove 14 can receive the condensed water dripping from the condenser to prevent the condensed water from dripping to the outside of the chassis 1, thereby meeting the drainage requirements of the condenser.

[0039] It is worth noting that in the related art, there is a large gap between the barrier wall 12 and the condenser, and the gap is used to ensure that the condensed water dripping from the condenser can drip onto the bottom wall 11. However, since a large gap is reserved between the barrier wall 12 and the condenser, it is necessary to extend the length of the bottom wall 11 to meet the requirement of forming a gap between the barrier wall 12 and the condenser, resulting in an increase in the overall space occupied by the chassis 1.

[0040] In this embodiment, since the water receiving groove 14 defined by the protrusion 13 can receive the condensed water dripping from the condenser, the blocking wall 12 can be moved toward the condenser and the length of the bottom wall 11 can be shortened accordingly, thereby reducing the overall space occupied by the chassis 1.

[0041] That is to say, in this embodiment, the chassis 1 effectively reduces the space occupied while ensuring the drainage requirements of the condenser.

[0042] Figure 3 This is a schematic structural diagram of the chassis 1 provided in this embodiment at a second viewing angle. Figure 4 for Figure 3 Please refer to the enlarged diagram of D in the figure. Figure 3 and Figure 4 In this embodiment, the bottom side of the protrusion 13 is located above the bottom side of the barrier wall 12. In this way, the protrusion 13 will not contact the ground, and there will be no floor space, thereby reducing the overall floor space of the chassis 1 and effectively saving space.

[0043] It should be noted that, in this embodiment, the terms "bottom", "top", "upper", "lower" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the chassis 1 is usually placed when in use. Figure 3 For example, Figure 3 The placement state of the middle chassis 1 can be understood as the usual placement state of the chassis 1 when it works normally.

[0044] Please refer to Figure 4 , Figure 4The directions indicated by arrows F and G can be understood as the height direction of the barrier wall 12. The inventor has found that if the distance between the top and bottom of the protrusion 13 in the height direction of the barrier wall 12 is large, then the bottom of the protrusion 13 is closer to the bottom side of the barrier wall 12, so that during the installation or transportation of the chassis 1, the bottom of the protrusion 13 is easy to collide with the ground, which is easy to damage the protrusion 13, resulting in a shorter service life of the protrusion 13. However, if the distance between the top and bottom of the protrusion 13 in the height direction of the barrier wall 12 is small, then the volume of the water receiving groove 14 defined by the protrusion 13 is small, so that the condensed water dripping into the water receiving groove 14 may overflow from the water receiving groove 14, thereby failing to meet the drainage requirements of the condenser. Therefore, in this embodiment, the distance between the top and bottom of the protrusion 13 in the height direction of the barrier wall 12 is limited to a certain range.

[0045] For details, please refer to Figure 4 In this embodiment, the distance between the top and bottom of the protrusion 13 in the height direction of the barrier wall 12 is B, 10mm≤B≤15mm. In this way, it can prevent the bottom of the protrusion 13 from colliding with the ground and extend the service life of the protrusion 13, while ensuring that the water receiving groove 14 defined by the protrusion 13 plays the role of receiving condensed water and meets the drainage requirements of the condenser.

[0046] Optionally, the distance B may be 10 mm, 13 mm, 15 mm, etc.

[0047] Please refer to Figure 4 The inventor has found that if the protrusion 13 is protruding from the outer surface of the barrier wall 12 at a greater height, the space occupied by the protrusion 13 will increase, thereby increasing the space occupied by the entire chassis 1. If the protrusion 13 is protruding from the outer wall of the barrier wall 12 at a smaller height, the volume of the water receiving groove 14 defined by the protrusion 13 is smaller, so that the condensed water dripping into the water receiving groove 14 may overflow from the water receiving groove 14, thereby failing to meet the drainage requirements of the condenser. Therefore, the embodiment also limits the protrusion 13 from the outer surface of the barrier wall 12 to a certain range.

[0048] For details, please refer to Figure 4 In this embodiment, the height of the protrusion 13 relative to the outer surface of the barrier wall 12 is A, 3mm≤A≤7mm. In this way, the space occupied by the protrusion 13 can be kept small, and the condensed water dripping into the water receiving groove 14 can be prevented from overflowing, thereby meeting the drainage requirements of the condenser.

[0049] Optionally, the height A may be 3 mm, 5 mm, 7 mm, etc.

[0050] It should be noted that, in the present embodiment, the outer surface of the aforementioned blocking wall 12 can be understood as a side surface of the blocking wall 12 away from the installation area 111 .

[0051] Figure 5 This is a schematic diagram of the structure of the chassis 1 provided in this embodiment without the protrusion 13. Figure 6 for Figure 5 The enlarged diagram of point E in the middle. Please refer to Figure 5 and Figure 6 , and combined with Figure 2 In this embodiment, the barrier wall 12 includes a first connecting wall 121, a second connecting wall 122 and a third connecting wall 123 connected in sequence, the top side of the second connecting wall 122 is lower than the top side of the first connecting wall 121, the top side of the second connecting wall 122 is lower than the top side of the third connecting wall 123, and the area between the first connecting wall 121, the second connecting wall 122 and the third connecting wall 123 can form a mounting notch 124, the aforementioned protrusion 13 is mounted in the mounting notch 124, and the protrusion 13 is simultaneously connected to the first connecting wall 121, the second connecting wall 122 and the third connecting wall 123. In this way, compared with the case where the protrusion 13 is only connected to one or two of the connecting walls, the connection stability of the protrusion 13 can be improved, the protrusion 13 is not easy to be separated, and the service life of the protrusion 13 can be extended.

[0052] Optionally, the protrusion 13 , the first connecting wall 121 , the second connecting wall 122 and the third connecting wall 123 may be connected by integral molding, welding or the like.

[0053] In this embodiment, the protrusion 13 , the first connecting wall 121 , the second connecting wall 122 and the third connecting wall 123 are integrally formed, so that the connection strength between the protrusion 13 , the first connecting wall 121 , the second connecting wall 122 and the third connecting wall 123 is relatively high.

[0054] It is understandable that the length of the second connecting wall 122 is equal to the length of the installation notch 124. Optionally, in practical applications, the length of the second connecting wall 122 can be adjusted according to the position and size of the condenser, so that the area of ​​the installation notch 124 can be aligned with the installation area 111 where the condenser is installed, thereby effectively ensuring that the water receiving groove 14 can accurately receive the condensed water dripping from the condenser.

[0055] Combination Figure 2 In the present embodiment, the protrusion 13 and the first connecting wall 121 are transitioned through an arc surface, which can reduce the stress between the protrusion 13 and the first connecting wall 121, avoid stress concentration between the protrusion 13 and the first connecting wall 121, thereby avoiding cracks at the connection between the protrusion 13 and the first connecting wall 121, and thus extending the service life of the protrusion 13 and the first connecting wall 121.

[0056] Similarly, in the present embodiment, the protrusion 13 and the second connecting wall 122 are transitioned through an arc surface, which can reduce the stress between the protrusion 13 and the second connecting wall 122 and avoid stress concentration between the protrusion 13 and the second connecting wall 122, thereby avoiding cracks at the connection between the protrusion 13 and the second connecting wall 122, thereby extending the service life of the protrusion 13 and the second connecting wall 122.

[0057] Similarly, in the present embodiment, the protrusion 13 and the third connecting wall 123 are transitioned through an arc surface, which can reduce the stress between the protrusion 13 and the third connecting wall 123 and avoid stress concentration between the protrusion 13 and the third connecting wall 123, thereby avoiding cracks at the connection between the protrusion 13 and the third connecting wall 123, thereby extending the service life of the protrusion 13 and the third connecting wall 123.

[0058] Optionally, in other embodiments, one or two of the first connecting wall 121 , the second connecting wall 122 and the third connecting wall 123 may transition to the protrusion 13 through an arc surface.

[0059] Please refer to Figure 2 and Figure 6 In this embodiment, the protrusion 13 includes a first transition wall 131, a protruding wall 132, a second transition wall 133 and a receiving wall 134. The first transition wall 131, the protruding wall 132 and the second transition wall 133 are connected in sequence. The side of the first transition wall 131 away from the protruding wall 132 is connected to the side of the first connecting wall 121 close to the installation notch 124. The side of the second transition wall 133 away from the protruding wall 132 is connected to the side of the third connecting wall 123 close to the installation notch 124. The receiving wall 134 is simultaneously connected to the bottom side of the first transition wall 131, the bottom side of the protruding wall 132, the bottom side of the second transition wall 133 and the top side of the second connecting wall 122. In this way, the area between the first transition wall 131, the protruding wall 132, the second transition wall 133 and the receiving wall 134 forms the aforementioned water receiving trough 14. The first transition wall 131, the protruding wall 132, the second transition wall 133 and the receiving wall 134 can all serve to receive condensed water. Under the joint blocking effect of the first transition wall 131, the protruding wall 132, the second transition wall 133 and the receiving wall 134, the condensed water dripping into the water receiving trough 14 is not easy to splash out of the water receiving trough 14, which can effectively prevent the condensed water from splashing on the ground outside the water receiving trough 14.

[0060] Combination Figure 2It should be noted that, in the present embodiment, the first transition wall 131 and the protruding wall 132 are transitioned through an arc surface, which can reduce the stress between the first transition wall 131 and the protruding wall 132, avoid stress concentration between the protruding wall 132 and the first transition wall 131, thereby avoiding cracks at the connection between the protruding wall 132 and the first transition wall 131, and further extending the service life of the protruding wall 132 and the first transition wall 131.

[0061] Similarly, in the present embodiment, the second transition wall 133 and the protruding wall 132 are transitioned through an arc surface, which can reduce the stress between the second transition wall 133 and the protruding wall 132, avoid stress concentration between the protruding wall 132 and the second transition wall 133, thereby avoiding cracks at the connection between the protruding wall 132 and the second transition wall 133, and further extending the service life of the protruding wall 132 and the second transition wall 133.

[0062] Similarly, in the present embodiment, the receiving wall 134 and the protruding wall 132 are transitioned through an arc surface, which can reduce the stress between the receiving wall 134 and the protruding wall 132, avoid stress concentration between the protruding wall 132 and the receiving wall 134, thereby avoiding cracks at the connection between the protruding wall 132 and the receiving wall 134, and further extending the service life of the protruding wall 132 and the receiving wall 134.

[0063] Optionally, in other embodiments, one or both of the first transition wall 131 , the second transition wall 133 and the receiving wall 134 may transition to the protruding wall 132 through an arc surface.

[0064] Combination Figure 2 It should be noted that, in this embodiment, the aforementioned arcuate transition between the protrusion 13 and the first connecting wall 121 can be understood as the arcuate transition between the first transition wall 131 and the first connecting wall 121. The aforementioned arcuate transition between the protrusion 13 and the second connecting wall 122 can be understood as the arcuate transition between the receiving wall 134 and the second connecting wall 122. The aforementioned arcuate transition between the protrusion 13 and the third connecting wall 123 can be understood as the arcuate transition between the second transition wall 133 and the third connecting wall 123.

[0065] Combination Figure 2 In this embodiment, a guiding slope 15 is provided in the water receiving groove 14. After the condensed water in the condenser drops into the water receiving groove 14, the guiding slope 15 can guide the condensed water in the water receiving groove 14 to flow toward the bottom wall 11 in the direction close to the installation area 111. The condensed water flowing toward the bottom wall 11 is finally discharged from the bottom pan 1 through the drainage structure on the bottom wall 11. It can be understood that the guiding slope 15 can effectively improve the drainage efficiency of the condensed water.

[0066] Optionally, the receiving wall 134 may be inclined, and the surface of the receiving wall 134 forms the aforementioned guiding inclined surface 15. Alternatively, an additional inclined wall may be provided on the receiving wall 134, and the surface of the inclined wall may form the aforementioned guiding inclined surface 15. The additional inclined wall and the receiving wall 134 may be connected by integral molding, welding, etc.

[0067] The above text describes that the protrusion 13, the first connecting wall 121, the second connecting wall 122 and the third connecting wall 123 are connected in an integrally formed manner. Specifically, in practical applications, the protrusion 13 is generally formed by a stamping process.

[0068] Combination Figure 2 In the present embodiment, the first transition wall 131 and the protruding wall 132 are arranged at an obtuse angle, so that after stamping, the stamping die can be demoulded more conveniently, thereby improving the production efficiency.

[0069] Similarly, combining Figure 2 and Figure 6 In this embodiment, the first transition wall 131 and the first connecting wall 121 are set at an obtuse angle, the second transition wall 133 and the protruding wall 132 are set at an obtuse angle, and the second transition wall 133 and the third connecting wall 123 are set at an obtuse angle. This can facilitate the demoulding of the stamping die and improve the production efficiency.

[0070] Optionally, in other embodiments, one of the first connecting wall 121 and the protruding wall 132 may be disposed at an obtuse angle to the first transition wall 131 .

[0071] Optionally, in other embodiments, one of the second connecting wall 122 and the protruding wall 132 may be disposed at an obtuse angle to the second transition wall 133 .

Generally, the air conditioner also includes an air conditioner indoor unit, which is interconnected with the air conditioner outdoor unit to achieve the function of adjusting the indoor temperature.

[0073] In summary, the present embodiment provides a chassis 1, an air conditioner outdoor unit and an air conditioner, which effectively reduce the space occupied while meeting the drainage requirements of the condenser.

[0074] Although the present invention is disclosed as above, the present invention is not limited thereto.

Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
