Description

air conditioner

[0001] The present disclosure relates to an air conditioner, and more specifically, to an air conditioner installed on a wall or ceiling.

[0002] An air conditioner can supply heat-exchanged air to an indoor space to regulate the temperature of the indoor space.

[0003] Wall-mounted air conditioners may have discharge outlets that open forward or downward. In a structure where only a single discharge outlet is formed, it is difficult to cover a wide area, making it difficult to achieve user satisfaction regarding comfort. Specifically, if the discharge outlet is formed forward, it is difficult to generate a direct airflow discharged toward the bottom of the air conditioner, and if the outlet is formed downward, there is a problem in delivering air over a long distance forward.

[0004] Korean Patent Publication KR 2020-0095936 discloses a structure of an air conditioner in which two discharge ports are formed.

[0005] However, a structure in which discharge ports are formed on multiple surfaces may be made into a structure combined with multiple structures due to structural peculiarities and issues such as injection molding.

[0006] A separate structure must be created for joining multiple structures. However, product reliability may be compromised in structures where the joining structure cannot be placed.

[0007]

[0008] The present disclosure aims to solve the aforementioned problems and other problems.

[0009] The air conditioner of the present disclosure has discharge ports formed on at least two surfaces. The purpose of the present disclosure is to provide an air conditioner in which the surfaces on which the discharge ports are formed are configured as separate discharge covers and the surfaces are stably joined together.

[0010] The air conditioner of the present disclosure may have discharge ports formed on three different sides. Additionally, fixed vanes may be disposed at at least two of the discharge ports. The object of the present disclosure is to provide an air conditioner that compartmentalizes and produces discharge covers that are difficult to injection mold as a single structure, and combines them.

[0011] Another objective is to provide an air conditioner capable of ensuring the reliability of a discharge cover combined with multiple structures.

[0012]

[0013] To achieve the above objective, an air conditioner according to an embodiment of the present disclosure comprises a case having an intake port, a first discharge port disposed on a lower surface, and a second discharge port disposed on a front surface, and a vane for opening and closing the first discharge port.

[0014] The above case includes an upper cover having an intake port formed therein, a first discharge cover having a first discharge port formed therein and disposed below the upper cover, and a second discharge cover having a second discharge port formed therein, with the upper end coupled to the upper cover and the lower end coupled to the first discharge cover.

[0015] The first discharge cover is joined to the second discharge cover by a fusion method.

[0016] The first discharge cover includes a front portion disposed in front of the first discharge port, side portions disposed on both sides of the first discharge port, and a rear portion disposed behind the first discharge port.

[0017] The rear portion is connected to the upper cover. The front portion and the side portion are coupled to the second discharge cover.

[0018] The second discharge cover includes a front wall in which the second discharge port is formed, and two side walls extending rearward from both ends of the front wall. The lower end of the front wall is coupled to the front part.

[0019] The front wall comprises a front lower wall in contact with the first discharge cover, a front upper wall in contact with the upper cover, and a plurality of front vanes spaced vertically apart between the front lower wall and the front upper wall.

[0020] The front-rear width of the above-mentioned front lower wall is formed to be smaller than the front-rear width of the above-mentioned front part.

[0021] The front-rear width of the above-mentioned front lower wall is formed to be smaller than the front-rear width of the above-mentioned front vane.

[0022] An insertion groove is formed in the front portion above, into which the front lower wall is disposed.

[0023] The above-mentioned front portion includes a front tip protruding upward from the front end and a rear tip protruding upward from the rear end. The lower portion of the front wall is positioned between the front tip and the rear tip.

[0024] A guide projection protruding upward is disposed on the side portion of the first discharge cover. The guide projection fixes the position of the second discharge cover positioned above the first discharge cover.

[0025] The second discharge cover includes a front wall in which the second discharge opening is formed, and two side walls extending rearward from both ends of the front wall. The side walls include a lower side wall in contact with the upper surface of the first discharge cover. A guide hole into which the guide projection is inserted is formed in the lower side wall.

[0026] A lateral tip is disposed on the outer side of the lateral lower wall of the first discharge cover.

[0027] A third discharge port is formed in the above-mentioned side wall.

[0028] A plurality of lateral vanes are arranged in the third discharge port of the aforementioned lateral wall, spaced vertically and inclined upward. A plurality of front vanes are arranged in the second discharge port of the aforementioned front wall, spaced vertically and inclined upward.

[0029] A locking projection protruding upward is disposed on the rear portion of the first discharge cover to engage with the upper cover.

[0031] A first member is disposed at the upper portion of the second discharge cover, positioned in front of the upper fixing projection, and coupled to the upper cover by magnetic force.

[0032] Specific details of other embodiments are included in the detailed description and drawings.

[0033] According to the air conditioner of the present disclosure, one or more of the following effects are provided.

[0034] First, the first discharge cover and the second discharge cover are joined by a fusion method, which has the advantage of allowing them to be joined without a separate joining structure. In addition, it provides a structure that can be stably joined even in a structure where there is no space to place a joining structure.

[0035] Second, there is also an advantage that the first discharge cover and the second discharge cover can be stably joined by fusing the front wall of the second discharge cover while it is inserted into the insertion groove of the first discharge cover.

[0036] Third, a guide projection protruding from the first discharge cover is inserted into a guide hole formed in the second discharge cover, so that the first discharge cover and the second discharge cover can be joined to each other at a predetermined position.

[0147] The front upper wall (136) has a structure that is bent downward from the center in the front-rear direction.

[0148] The length (136W) of the front upper wall (136) formed in the front-rear direction may be longer than the length (138L) of the front vane (138) formed in the front-rear direction. The length (136W) of the front upper wall (136) formed in the front-rear direction may be longer than the width (134W) of the front lower wall (134) formed in the front-rear direction.

[0149] The front vane (138) forms an inclined surface toward the front and upper side. Therefore, the front vane (138) can guide the air discharged through the second discharge port (16) toward the front and upper side.

[0150] Since the length formed by the front lower wall (134) in the front-rear direction is shorter than the length formed by the front vane (138) in the front-rear direction, the front lower wall (134) can be formed with a relatively narrow width.

[0151] Therefore, it is difficult to provide a separate structure for coupling with the first discharge cover (110) on the front lower wall (134). Additionally, since the front lower wall (134) is formed in a relatively narrow area, its relative strength may be weak. Therefore, coupling through a separate structure may cause the shape of the front lower wall (134) to deform or be damaged.

[0152] In the present invention, the front lower wall (134) is inserted into an insertion groove (114c) formed in the front part (112) of the first discharge cover (110) and has a structure that is joined by a fusion method. Accordingly, the front lower wall (134), having a relatively thin thickness and width, can be stably joined to the first discharge cover (110).

[0153] The gap (D1) between the front lower wall (134) and the front vane (138) positioned adjacent to the front lower wall (134) is formed to be smaller than the gap (D2) between the plurality of front vanes (138). The gap (D3) between the front upper wall (136) and the front vane (138) positioned adjacent to the front upper wall (136) is formed to be equal to or larger than the gap (D2) between the plurality of front vanes (138).

[0154] The thickness of each front vane (138) formed in the vertical direction decreases as it goes from the rear to the front.

[0155] Referring to FIG. 8, the side wall structure of the second discharge cover and the connection relationship with the first discharge cover will be explained.

[0156] A third discharge port (18) is formed in the side wall (150). The side wall (150) includes a side vane (156) that guides the air discharged through the third discharge port (18) upward. The side vane (156) may have a shape that slopes upward as it extends outward. A plurality of side vanes (156) may be provided spaced apart in the vertical direction.

[0157] The side wall (150) includes a side lower wall (152) that contacts the first discharge cover (110). The side lower wall (152) can be joined to the first discharge cover (110) by a fusion method.

[0158] A lateral tip (118) is disposed on the outer side of the lateral lower wall (152) of the first discharge cover (110). The lateral tip (118) protrudes upward from the outer end of the lateral portion (116) of the first discharge cover (110). The second discharge cover (130) can be stably disposed on top of the first discharge cover (110) by means of the lateral tip (118).

[0159] The side wall (150) includes a side upper wall (157) facing the upper cover (20). A guide rib (158) may be disposed on the side upper wall (157). The guide rib (158) may be inserted into a rib hole (30) formed in the upper cover (20).
