These ribs support the outer side of the heat exchanger and abut against the face frame covering the chassis. The positioning ribs position the heat exchanger and, by abutting against the face frame, provide a water-blocking effect. Condensate from the heat exchanger flows along the positioning ribs into the water-receiving groove formed by the positioning ribs and support ribs, reducing condensate leakage. The positioning ribs provide both positioning and water-blocking functions, reducing the number of ribs and decreasing the chassis thickness along the front-to-back direction, thus reducing the thickness of the air conditioner. With other dimensions of the air conditioner remaining constant, the lower thickness allows for a larger number of air conditioners to be transported at once, reducing the transportation cost per unit.

Detailed Implementation

[0031] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0039] In related technologies, the chassis of an air conditioner is formed with supporting ribs, positioning ribs, and water-blocking ribs sequentially from the inside out. The supporting and positioning ribs support the bottom and outer side of the heat exchanger, respectively, to position the heat exchanger. The water-blocking ribs, located outside the positioning ribs, prevent condensate from the heat exchanger from flowing into the external space. The large number of ribs in the chassis results in a significant chassis thickness and a large overall size of the assembled air conditioner. This leads to higher transportation costs due to the limited number of air conditioners that can be transported at once.

[0040] The positioning ribs 130 in this embodiment of the application serve to position the heat exchanger 400 and block water. The chassis 100 has fewer ribs, reducing the thickness of the base plate and thus reducing the thickness of the air conditioner. The thinner size of the air conditioner allows for the transport of a larger number of air conditioners in a single shipment, thereby reducing transportation costs.

[0041] This application intends to provide an air conditioner; please refer to [link / reference]. Figures 1 to 3The air conditioner includes a chassis 100, a heat exchanger 400, and a front frame 200. The chassis 100 includes a chassis body 110, support ribs 120, and positioning ribs 130. The support ribs 120 and 130 are respectively connected to the chassis body 110. The positioning ribs 130 and support ribs 120 are spaced apart, and a water collection groove 130a is provided between the positioning ribs 130 and support ribs 120. The heat exchanger 400 is mounted on the chassis 100, with the support ribs 120 supporting the bottom of the heat exchanger 400. The water collection groove 130a is used to collect condensate from the heat exchanger 400. The front frame 200 covers the chassis 100. The inner side of the positioning ribs 130 supports the side of the heat exchanger 400 facing the front frame 200, and the outer side of the positioning ribs 130 abuts against the front frame 200.

[0042] For example, the inner side of the positioning rib 130 refers to the side of the positioning rib 130 facing the support rib 120, and the outer side of the positioning rib 130 refers to the side of the positioning rib 130 away from the support rib 120.

[0043] For example, both the support rib 120 and the positioning rib 130 are ribs extending along the length of the chassis 100. The support rib 120 and the positioning rib 130 are essentially strip-shaped structures, with the length of the positioning rib 130 arranged parallel to the length of the chassis 100. Projected along the length of the chassis 100, the projection area of ​​the positioning rib 130 gradually slopes downwards towards the support rib 120. The inclined positioning rib 130, in addition to positioning the heat exchanger 400, also guides the condensate flow, allowing it to collect effectively in the water collection tank 130a.

[0044] For example, the up and down direction is as follows Figure 1 The direction indicated by the middle arrow R1. The length direction of chassis 100 is as follows... Figure 1 The direction indicated by the middle arrow R2. The thickness direction is as follows. Figure 1 The direction indicated by the middle arrow R3.

[0045] For example, when an air conditioner is mounted on a vertical wall, it is arranged in a direction parallel to the vertical direction.

[0046] In this embodiment, the chassis 100 includes positioning ribs 130 connected to the chassis body 110. The positioning ribs 130 support the outer side of the heat exchanger 400 and abut against the face frame 200 covering the chassis 100. The positioning ribs 130 position the heat exchanger 400, and their contact with the face frame 200 provides a water-blocking effect. Condensate from the heat exchanger 400 flows along the positioning ribs 130 into the water collection groove 130a formed by the positioning ribs 130 and the support ribs 120, thus reducing condensate leakage. The positioning ribs 130 provide both positioning and water-blocking functions, reducing the number of ribs and decreasing the thickness of the chassis 100 along the front-to-back direction, thereby reducing the thickness of the air conditioner. With other dimensions of the air conditioner fixed, a lower thickness allows for a larger number of air conditioners to be transported at once, reducing the transportation cost per unit.

[0047] For example, the air conditioner also includes a panel 300, which covers the face frame 200. The panel 300 includes a display component, through which the user can observe the current set temperature and set the fan speed mode of the air conditioner.

[0048] In one embodiment, please refer to Figure 7 and Figure 8 The positioning rib 130 has a clearance portion 130b and a water-blocking portion 130c. The clearance portion 130b and the water-blocking portion 130c are arranged along the length direction of the positioning rib 130, and the width of the clearance portion 130b is smaller than the width of the water-blocking portion 130c. Since the width of the clearance portion 130b of the positioning rib 130 is smaller than the width of the water-blocking portion 130c, the positioning rib 130 as a whole forms a stepped shape. Part of the structure of the face frame 200 can extend from above the clearance portion 130b into the space of the positioning rib 130 facing the heat exchanger 400, thereby making full use of the dimensions of the air conditioner in the thickness direction and further reducing the dimensions of the air conditioner in the thickness direction.

[0049] In another embodiment, the avoidance portion 130b and the water-blocking portion 130c have a smooth transition.

[0050] It is understood that other embodiments of this application are not limited to the positioning rib 130 having a clearance portion 130b and a water-blocking portion 130c. Exemplarily, the positioning rib 130 may be a rib of an approximately rectangular plate.

[0051] In one embodiment, the width of the projection area of ​​the water-blocking part 130c, projected along the vertical direction, ranges from 7 mm to 10 mm.

[0052] For example, when projected along the vertical direction, the width of the projected area of ​​the water-retaining part 130c is 7.0mm, 7.5mm, 8.0mm, 8.5mm, 9.0mm, 9.5mm, or 10.0mm. It is understood that the width of the projected area of ​​the water-retaining part 130c can be obtained by measuring with a ruler under normal temperature and pressure conditions.

[0053] For example, the width dimension of the projected area of ​​the water-blocking part 130c is as follows: Figure 6 As shown in the medium dimension D1.

[0054] In the embodiment of this application, the width of the projected area of ​​the water-blocking part 130c is within a suitable range, so that the positioning rib 130 can minimize the flow of condensate water to the outside of the water receiving tank 130a, while also taking into account the small thickness of the chassis 100.

[0055] Understandably, air conditioners also contain movable parts such as air deflectors and louvers. These movable parts require corresponding motors to drive their movement through wires, which are usually run inside the air conditioner.

[0056] In one embodiment, please refer to Figure 4 and Figure 5 The chassis 100 also includes a wire buckle assembly 140 connected to the chassis body 110. The wire buckle assembly 140 is located on the side of the positioning rib 130 away from the support rib 120 and is used to fix the wire.

[0057] For example, the number of wires can be single or multiple.

[0058] In this embodiment of the application, the chassis 100 is equipped with a wire clip assembly 140 to fix the wires. During the assembly of the air conditioner, the wire clip assembly 140 can position the wires, thereby facilitating the wiring process for operators. Furthermore, the wire clip assembly 140 can fix the wires, reducing the possibility of displacement during operation. Moreover, the wire clip assembly 140 is located on the side of the positioning rib 130 away from the support rib 120. The wire clip assembly 140 can fix the wires as far away as possible from the water collection tank 130a, reducing contact between the wires and condensate, thereby reducing the risk of short circuits.

[0059] In one embodiment, please refer to Figure 4 There are multiple wire clip assemblies 140, which are arranged at intervals along the length of the positioning rib 130. The multiple wire clip assemblies 140 work together to fix the wire, so that the installation of the wire is more stable.

[0060] In one embodiment, please refer to Figure 5The wire fastener assembly 140 includes a first fastener 141 and a second fastener 142 arranged along the length of the positioning rib 130. Both the first fastener 141 and the second fastener 142 are connected to the chassis body 110. When the wire fastener assembly 140 fixes the corresponding wire, the first fastener 141 abuts against the lower part of the wire, and the second fastener 142 abuts against the upper part of the wire. The first fastener 141 protrudes upward to form a first protrusion 141a, which is located on the side of the wire away from the positioning rib 130. The second fastener 142 protrudes along the length of the positioning rib 130 to form a second protrusion 142a, which is located on the side of the wire away from the positioning rib 130.

[0061] For example, the first protrusion 141a and the second protrusion 142a both abut against the side of the wire away from the positioning rib 130.

[0062] In the embodiment of this application, the first fixing member 141 and the second fixing member 142 are respectively abutted against the lower and upper parts of the corresponding wires to fix the wires. Furthermore, the first fixing member 141 and the second fixing member 142 are respectively formed with a first protrusion 141a and a second protrusion 142a on the side of the wire away from the positioning rib 130. The first protrusion 141a and the second protrusion 142a can reduce the degree of wire warping, thereby reducing the interference between the face frame 200 and the wires.

[0063] It is understood that other embodiments of this application do not limit the structural form of the second fastener 142. Exemplarily, the shape of the second fastener 142 may be a cylinder.

[0064] In one embodiment, please refer to Figure 5 The number of second fasteners 142 is at least two. The first fastener 141 is provided with second fasteners 142 on both sides along the length direction of the positioning rib 130. The protrusion direction of the second protrusion 142a of the second fastener 142 is facing the corresponding first fastener 141.

[0065] For example, there are two second fasteners 142, which are located on both sides of the first fastener 141 along the length of the positioning rib 130, with the first fastener 141 located in the middle of the two second fasteners 142. The protrusion directions of the second protrusions 142a corresponding to the second fasteners 142 located on both sides of the first fastener 141 are opposite.

[0066] In the embodiment of this application, there are at least two second fixing members 142. The first fixing member 141 is provided with second fixing members 142 on both sides along the length direction. The force on the wire is relatively uniform, and the wire buckle assembly 140 has a high fixing effect on the wire.

[0067] In one embodiment, the chassis 100 further includes a thermal insulation element that is attached to the positioning rib 130 and located on the side of the positioning rib 130 opposite to the support rib 120. The thermal insulation element has an opening to avoid the wire clip assembly 140. The thermal insulation element can be used to insulate the positioning rib 130, preventing excessive condensation on the sides of the positioning rib 130, which could lead to a short circuit. For example, the thermal insulation element can be made of sponge.

[0068] In one embodiment, please refer to Figure 3 The face frame 200 has a guide surface 200a on the side facing the inside of the positioning machine. The guide surface 200a gradually slopes from top to bottom toward the positioning rib 130 and abuts against the top of the positioning rib 130.

[0069] For example, the guide surface 200a extends along the length direction of the positioning rib 130.

[0070] In this embodiment, the guide surface 200a is an inclined surface that abuts against the top of the positioning rib 130. When the heat exchanger 400 generates condensate, the condensate may splash as it drips onto the chassis 100, continuously accumulating into water droplets on the side wall of the frame 200. These water droplets can flow along the inclined guide surface 200a towards the positioning rib 130, and then into the water collection tank 130a. The guide surface 200a guides the flow of condensate, reducing the amount of condensate accumulating outside the water collection tank 130a.

[0071] It is understood that the embodiments of this application do not limit the shape of the guide surface 200a. Exemplarily, the guide surface 200a is arranged vertically from top to bottom.

[0072] In one embodiment, please refer to Figure 3 The face frame 200 also has a water-receiving rib 200b, which is located above the positioning rib 130. The water-receiving rib 200b is connected to the guide surface 200a and is projected in the vertical direction. The projection area of ​​the water-receiving rib 200b spans the projection area of ​​the guide surface 200a and the projection area of ​​the positioning rib 130.

[0073] For example, the water-receiving rib 200b is integrally formed with the guide surface 200a. The overall strength of the face frame 200 is high, and its service life is long. The extension direction of the water-receiving rib 200b is arranged parallel to the length direction of the positioning rib 130.

[0074] The projection area of ​​the water-receiving rib 200b spans the projection area of ​​the guide surface 200a and the projection area of ​​the positioning rib 130, meaning that the projection areas of the guide surface 200a and the positioning rib 130 both overlap with the projection area of ​​the water-receiving rib 200b.

[0075] For example, along the length of the positioning rib 130, the water-receiving rib 200b is positioned above the clearance portion 130b. The water-receiving rib 200b can, to some extent, reduce the leakage of condensate caused by the positioning rib 130's small width due to the clearance portion 130b. Part of the structure of the water-receiving rib 200b can extend from above the clearance portion 130b to the side of the positioning rib 130 facing the support rib 120.

[0076] In the embodiment of this application, the projection of the water-receiving rib 200b spans the projection area of ​​the guide surface 200a and the projection area of ​​the positioning rib 130 along the vertical direction. When condensate generated by the heat exchanger 400 drips from above, the water-receiving rib 200b can contact the condensate outside the positioning rib 130, thereby guiding the condensate into the water-receiving tank 130a, further reducing the possibility of condensate leakage caused by condensate flowing outside the chassis 100.

[0077] It is understood that other embodiments of this application do not limit whether the faceplate 200 has a water-receiving rib 200b.

[0078] It is understandable that setting a water-receiving rib 200b above the positioning rib 130 can increase the water-receiving capacity of the chassis 100, thereby further reducing the leakage of condensate. However, the distance between the water-receiving rib 200b and the chassis 100 will affect the difficulty of condensate flowing to the water-receiving tank 130a after contacting the water-receiving rib 200b.

[0079] In one embodiment, the distance between the water-receiving rib 200b and the positioning rib 130 in the vertical direction ranges from 4mm to 10mm.

[0080] For example, the distance between the water-receiving rib 200b and the positioning rib 130 in the vertical direction is 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, or 10mm. It is understood that the distance between the water-receiving rib 200b and the positioning rib 130 can be measured with a ruler under normal temperature and pressure conditions.

[0081] For example, the distance between the water-receiving rib 200b and the positioning rib 130 in the vertical direction is as follows: Figure 2 As shown in the medium dimension D2.

[0082] In the embodiment of this application, the distance between the water-receiving rib 200b and the positioning rib 130 along the vertical direction is within a suitable range so that when the water-receiving rib 200b comes into contact with condensate, the condensate can flow smoothly along the water-receiving rib 200b to the positioning rib 130. It can also reduce the interference between the water-receiving rib 200b and the positioning rib 130 during the installation of the face frame 200 onto the chassis 100.

[0083] It is understandable that when condensate comes into contact with the water-receiving rib 200b, it will flow along the shape of the water-receiving rib 200b. In one embodiment, the water-receiving rib 200b gradually tilts towards the positioning rib 130 in a top-to-bottom direction.

[0084] In the embodiment of this application, the water receiving rib 200b gradually tilts toward the positioning rib 130, so that the condensate can flow smoothly toward the positioning rib 130 when it comes into contact with the water receiving rib 200b, and thus collect in the water receiving tank 130a, thereby reducing the situation where condensate condenses above the water receiving rib 200b.

[0085] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and all should be covered within the scope of the specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of protection.
