Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an air conditioner. Background Technology

[0002] In related technologies, the air outlet of an air conditioner uses a sliding door. When the sliding door is open, a gap usually forms between it and the air conditioner's casing. Therefore, in cooling mode, when cold air exits the outlet, some of it may enter this gap, causing condensation on the door, which affects the customer experience. Utility Model Content

[0003] The main purpose of this invention is to propose an air conditioner that aims to reduce the probability of condensation when opening and closing doors.

[0004] To achieve the above objectives, the air conditioner proposed in this utility model includes: The casing is equipped with an air outlet; A sliding door is provided at the air outlet to have a first state with the air outlet open and a second state with the air outlet closed. The sliding door has opposing first and second sides. In the first state, the first side is close to the edge of the air outlet. The first sealing strip includes a sealing body installed on the first side, and a first sealing rib and a second sealing rib both connected to the sealing body. The second sealing rib is spaced apart on the side of the first sealing rib closer to the second side. In the first state, both the first sealing rib and the second sealing rib are sealed and abutted against the edge of the air outlet.

[0005] In one embodiment, the first sealing rib abuts against the wall surface of the air outlet.

[0006] In one embodiment, the outer surface of the housing is provided with overlapping ribs spaced apart from the outlet wall, and the second sealing rib abuts against the overlapping ribs.

[0007] In one embodiment, the housing is provided with a water collection tray lower than the air outlet, the first side extends in the vertical direction, and the lower end of the first sealing strip is provided with a flow guiding structure, which is used to guide the condensate towards the water collection tray.

[0008] In one embodiment, the lower end face of the first sealing rib and / or the second sealing rib extends downward at an angle away from the sealing body to form the flow guiding structure.

[0009] In one embodiment, the angle between the lower end face of the first sealing rib and / or the second sealing rib and the horizontal plane is in the range of 30° to 70°.

[0010] In one embodiment, there are two doors, which are brought close together to close the air outlet; The sealing body of the first sealing strip on one of the switch doors has an abutting protrusion on the surface facing the other switch door; in the second state, there is a gap between the two switch doors, and the gap is sealed by the abutting protrusions abutting against each other.

[0011] In one embodiment, the sealing body has a deformation cavity.

[0012] In one embodiment, the abutting protrusion is configured as an arcuate protrusion.

[0013] In one embodiment, the air conditioner further includes a second sealing strip, which is installed on the second side and, in the second state, the second sealing strip is in sealing contact with the housing.

[0014] The technical solution of this utility model involves providing a first sealing strip on the first side of the switch door. In the first state where the switch door is open and the air outlet is open, the first sealing strip seals the gap between the first side and the edge of the air outlet, preventing cold air in cooling mode from entering between the switch door and the outer surface of the casing, thereby reducing the probability of condensation on the switch door. It is worth emphasizing that the first sealing strip in this embodiment is also provided with a first sealing rib and a second sealing rib. In the first state, both the first and second sealing ribs are sealed and abut against the edge of the air outlet. Thus, when the air conditioner is operating in cooling mode, the cold air blown out of the air outlet will first pass through the first sealing rib, which prevents the cold air from entering the gap between the switch door and the outer surface of the casing. If some residual cold air enters after passing through the first sealing rib, the second sealing rib will provide a sealing effect. In other words, the first sealing strip in this embodiment has a double sealing function, improving the effectiveness of the switch door in preventing condensation. Attached Figure Description

[0021] This utility model proposes an air conditioner.

[0022] Reference Figure 1 , Figure 6 and Figure 7 In one embodiment of this utility model, the air conditioner includes: The casing 1 is equipped with an air outlet 10; The switch door 2 is slidably disposed at the air outlet 10, having a first state with the air outlet 10 open and a second state with the air outlet 10 closed. The switch door 2 has opposing first and second sides. In the first state, the first side is close to the edge of the air outlet 10. The first sealing strip 3 includes a sealing body 31 installed on the first side, and a first sealing rib 32 and a second sealing rib 33 both connected to the sealing body 31. The second sealing rib 33 is spaced apart on the side of the first sealing rib 32 near the second side. In the first state, the first sealing rib 32 and the second sealing rib 33 are both sealed and abutted against the edge of the air outlet 10.

[0023] In this embodiment, the housing 1 can be the housing of a vertical indoor unit of a split-type air conditioner, or the housing of a vertical wall-mounted unit of a split-type air conditioner. However, this design is not limited to this; the housing 1 can also be the housing of an integrated air conditioner. Typically, it is the housing of an integrated air conditioner that uses a vertical cross-flow fan to supply air to the room, and its air outlet 10 is an indoor side air outlet, usually arranged in a rectangular shape extending vertically along its length.

[0024] In this embodiment, the first sealing strip 3 extends along the first side, and correspondingly, the sealing body 31, the first sealing rib 32, and the second sealing rib 33 all extend along the first side.

[0025] The technical solution of this utility model is to provide a first sealing strip 3 on the first side of the switch door 2, so that when the switch door 2 is in the first state of opening the air outlet 10, the first sealing strip 3 seals the gap between the first side and the edge of the air outlet 10, so as to prevent cold air in the cooling mode from entering between the switch door 2 and the outer surface of the housing 1, thereby reducing the probability of condensation on the switch door 2. It is worth emphasizing that the first sealing strip 3 in this embodiment is provided with a first sealing rib 32 and a second sealing rib 33. In the first state, both the first sealing rib 32 and the second sealing rib 33 are sealed and abutted against the edge of the air outlet 10. Thus, when the air conditioner is working in cooling mode, the cold air blown out from the air outlet 10 will first pass through the first sealing rib 32. The first sealing rib 32 will prevent the cold air from entering the gap between the switch door 2 and the outer surface of the casing 1. If some residual cold air enters after the cold air passes through the first sealing rib 32, the second sealing rib 33 will play a sealing role. That is, the first sealing strip 3 in this embodiment has a double sealing function, which can improve the anti-condensation effectiveness of the switch door 2.

[0026] In one embodiment, reference is made to Figure 7 The first sealing rib 32 abuts against the wall surface of the air outlet 10. Specifically, the side of the first sealing rib 32 closest to the second sealing rib 33 at the end away from the sealing body 31 abuts against the wall surface of the air outlet 10. This embodiment increases the effective sealing distance between the first sealing rib 32 and the air outlet 10 by the surface-to-surface contact between the first sealing rib 32 and the wall surface of the air outlet 10, thereby improving the sealing effect of the first sealing rib 32 and reducing the probability of cold air bypassing the first sealing rib 32. Optionally, the edge of the air outlet 10 is provided with an outwardly turned flange (not shown) to further increase the effective sealing distance between the first sealing rib 32 and the air outlet 10.

[0027] Furthermore, the outer surface of the housing 1 is provided with overlapping ribs 11 spaced apart from the opening wall of the air outlet 10, and the second sealing rib 33 abuts against the overlapping ribs 11. In this embodiment, the second sealing rib 33 abuts against the side of the overlapping rib 11 closest to the air outlet 10. It can be understood that the second sealing rib 33 and the overlapping rib 11 are also in surface-to-surface contact. Therefore, the addition of the overlapping rib 11 helps to increase the effective sealing distance of the second sealing rib 33, thereby improving the sealing effect of the second sealing rib 33 and reducing the probability of residual cold air bypassing the second sealing rib 33. In this embodiment, the height of the second sealing rib 33 is usually less than the height of the first sealing rib 32, the height of the overlapping rib 11 is usually higher than the height of the flange, and there is a gap between the second sealing rib 33 and the flange in the axial direction of the air outlet 10, so that the second sealing rib 33 can pass over the flange during the opening of the door 2, thereby ensuring that the second sealing rib 33 can abut against the overlapping rib 11 in the first state.

[0028] In this embodiment, the first sealing rib 32 abuts against the wall surface of the air outlet 10, and the second sealing rib 33 abuts against the overlapping protruding rib 11 provided on the outer surface of the housing 1; however, this design is not limited to this. In other embodiments, the first sealing rib 32 and the second sealing rib 33 may also abut against the outer surface of the outer edge of the air outlet 10 of the housing 1.

[0029] In one embodiment, reference is made to Figures 2 to 4 , Figure 7 The unit has two opening and closing doors 2. The two doors 2 are positioned close to each other to close the air outlet 10, and spaced apart to open the air outlet 10. Optionally, the two doors 2 are driven by different drive mechanisms. These two drive mechanisms typically operate synchronously, but they can also operate independently to open only one door 2, thus meeting the small-scale air supply needs of some users during special times. Optionally, the two drive mechanisms are located at opposite ends of the air outlet 10 (for example, when the two doors 2 open and close in the left-right direction, the two drive mechanisms are located at the upper and lower ends of the air outlet 10), to better utilize the installation space at opposite ends of the air outlet 10, resulting in a more rational product structure layout.

[0030] In this embodiment, the sealing body 31 of the first sealing strip 3 on one of the switch doors 2 has an abutting protrusion 311 on its surface facing the other switch door 2. In the second state, there is a gap between the two switch doors 2, and the two abutting protrusions 311 abut against each other to seal the gap. In this embodiment, when the air conditioner stops working and the two switch doors 2 are closed, the two abutting protrusions 311 of the two first sealing strips 3 on the two switch doors 2 will preferentially contact each other to achieve soft contact, thereby solving the closing noise problem of the two switch doors 2. Optionally, the abutting protrusion 311 is configured as an arc-shaped protrusion, which is beneficial to have a larger contact sealing area when the two abutting protrusions 311 contact each other, thereby helping to ensure a larger effective sealing distance when the two abutting protrusions 311 contact each other; however, this design is not limited to this. In other embodiments, the cross-section of the abutting protrusion 311 can also be a protrusion of other shapes, as long as effective sealing contact can be generated between the two abutting protrusions 311 in the second state. Optionally, the sealing body 31 is provided with a deformation cavity 312 to increase the elasticity of the sealing body 31, thereby providing more effective soft contact for the two abutting protrusions 311 and further reducing closing noise.

[0031] In one embodiment, reference is made to Figure 5 The air conditioner also includes a second sealing strip 4, which is installed on the second side. In the second state, the second sealing strip 4 is in sealing contact with the housing 1 to seal the gap between the second side of the switch door 2 and the outer surface of the housing 1. This reduces the probability of insects entering the housing 1 through the gap between the second side of the switch door 2 and the outer surface of the housing 1 when the switch door 2 closes the air outlet 10.

[0032] Optionally, the housing 1 is provided with a mating rib 13 corresponding to the second sealing strip 4, and the second sealing strip 4 abuts against the mating rib 13 to improve the sealing effectiveness of the second sealing strip 4. In this embodiment, the mating rib 13 and the overlapping rib 11 are spaced apart, and the second sealing strip 4 abuts against the side of the mating rib 13 away from the overlapping rib 11.

[0033] Optionally, the material of the first sealing strip 3 and / or the second sealing strip 4 may be, but is not limited to, silicone, rubber (e.g., but not limited to neoprene), fluororubber, TPS, TPA, etc.

[0034] In the preceding embodiments, the first and second side edges can be horizontal, vertical, or diagonal. In the following embodiments, both the first and second side edges extend vertically. (Refer to...) Figures 8 to 11The housing 1 is provided with a water collection tray 12 that is lower than the air outlet 10. The lower end of the first sealing strip 3 is provided with a flow guiding structure 34, which is used to guide the condensate towards the water collection tray 12. In this way, when the air conditioner is working in cooling mode, the condensate on the first sealing strip 3 flows downward to the lower end and can be guided to the water collection tray 12 by the flow guiding structure 34, thereby preventing the condensate from flowing to the ground and avoiding affecting the user experience.

[0035] Optionally, the lower end faces of the first sealing rib 32 and / or the second sealing rib 33 extend downward at an angle away from the sealing body 31 to form the flow guiding structure 34. The technical solution of this embodiment directly sets the lower end faces of the first sealing rib 32 and / or the second sealing rib 33 at an angle to guide the condensate flow. This flow guiding structure 34 is relatively simple and beneficial for product manufacturing. However, this design is not limited to this. In other embodiments, the lower ends of the first sealing rib 32 and / or the second sealing rib 33 can be set horizontally, and additional downwardly extending flow guiding ribs can be provided at the horizontal lower ends to form the flow guiding structure 34.

[0036] Optionally, the angle between the lower end face of the first sealing rib 32 and / or the second sealing rib 33 and the horizontal plane is in the range of 30° to 70°, and the flow guiding structure 34 within this angle range has good flow guiding ability.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the scope of protection of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
