Description

BACKGROUND

1. Field

An air conditioner and an installation kit are disclosed herein.

2. BACKGROUND

An air conditioner is a device for supplying conditioned air to an indoor space by cooling, heating, or purifying intake air. A window-mounted air conditioner is mounted between a window frame and a window and supplies conditioned air to an indoor space. The window-mounted air conditioner typically includes an inlet and an outlet which are open toward the indoor space, and an outer surface opposite to the outlet and that faces the outside.

A separate installation frame for supporting the air conditioner may be installed at the window and the window frame. However, a window-mounted air conditioner typically do not include a separate finishing member that is provided at a front of the installation frame, such that noise and vibration generated by the air conditioner may be transmitted to the indoor space, and rainwater may enter from the outside and flow into the indoor space. In addition, a height of a known installation frame typically cannot be adjusted according to a window size, such that a gap is formed between the frame, the window, and the window frame, thereby degrading sealing and insulation performance of the frame. Furthermore, known installation are typically difficult to install in a window frame, typically include various types of components, and typically have require a complicated assembly of the components.

The pairs of the plurality of support ribs 112 may face each other with the opening 101 disposed therebetween.

The first coupling part 115 and the second coupling part 116 may be symmetrical about the center line C. The first coupling part 115 may be formed on one side of the opening 101, and the second coupling part 116 may be formed on another side of the opening 101. The opening 101 may be formed between the first coupling part 115 and the second coupling part 116. The first coupling part 115 and the second coupling part 116 may face each other with the opening 101 disposed therebetween.

Pairs thehe plurality of support ribs 117 may be provided symmetrically about the center line C. For example, one of the plurality of support ribs 117 may be formed on one side of the opening 101, and another corresponding one of the plurality of support ribs 117 may be formed on another side of the opening 101.

The front panel 110 may include a cord pass-through part (or cord pass-through opening) 118. The cord pass-through part 118 may be a space through which a wire or cord (not shown) connected to the air conditioner 1 passes. The cord pass-through part 118 may be formed at a lower portion of the front panel 110. The cord pass-through part 118 may be recessed forward. The cord pass-through part 118 may be formed under the opening 101 when the front panel is installed in space 93, 94.

Referring to FIGS. 8 and 9, the installation kit 100 will be described below. FIG. 8 is an enlarged view of an upper portion of the front panel 110, and FIG. 9 is an enlarged view of the plate 114 of front panel 110. The front panel 110 may include an edge 119. The edge 119 may be formed at both side ends of the front panel 110. The edge 119 may include a lip that protrudes further rearward than the plate 114. The edge 119 may be formed outside of the opening 101. The edge 119 may be formed outside of the coupling ribs 111.

The plate 114 may have a cutting groove 1141. A plurality of cutting grooves 1141 may be formed to be vertically spaced apart from each other. The cutting grooves 1141 may be recessed forward from a rear surface of the plate 114. The cutting grooves 1141 may extend in the horizontal direction. The cutting grooves 1141 may be formed above the opening 101. The plurality of cutting grooves 1141 may be vertically spaced apart from each other. Gaps G1 to G9 may be formed between the plurality of cutting grooves 1141. The coupling ribs 111 may be disposed between the plurality of cutting grooves 1141. The coupling ribs 111 may protrude rearward from a cutting plate (or cutting plate region) 1142.

The plate 114 may include at least one of the cutting plate 1142. A plurality of cutting plates 1142 may be arranged in the vertical direction. The cutting plates 1142 may be a portion of the plate 114. Each of the cutting plates 1142 may extend in the horizontal direction. The cutting plates 1142 may be disposed above the opening 101. The plurality of cutting plates 1142 may be formed as one body.

The cutting grooves 1141 may be formed between the plurality of cutting plates 1142. The cutting plates 1142 may be formed between the plurality of cutting grooves 1141.

The plurality of cutting plates 1142 may include, for example, a first cutting plate 1142a, a second cutting plate 1142b, a third cutting plate 1142c, and a fourth cutting plate 1142d. The first to fourth cutting plates 1142a, 1142b, 1142c, and 1142d may be respectively referred to as the first, second, third, and fourth cutting plates in order from top to bottom. However, the number and names of the cutting plates 1142 are not limited thereto.

The plurality of cutting grooves 1141 may include a first cutting groove 1141a and a second cutting groove 1141b. The first cutting groove 1141a and may be disposed above the second cutting groove 1141b. The first cutting groove 1141a may be formed between the first cutting plate 1142a and the second cutting plate 1142b. The second cutting groove 1141b may be formed between the second cutting plate 1142b and the third cutting plate 1142c.

A user may adjust a vertical height of the front panel 110 by applying force to the plate 114. The user may adjust the vertical height of the front panel by bending the plate 114 to cut and remove one or more of the plurality of cutting plates 1142 from the front panel 110. For example, by bending the first cutting plate 1142a toward the rear in a first rotational direction P around the first cutting groove 1141a and/or by bending the second cutting plate 1142b in a second direction Q opposite to the first direction P, the front panel 110 may be cut at the first cutting groove 1141a. Due to the cut at the first cutting groove 1141a, the first cutting plate 1142a may be separated from the front panel 110. After the first cutting plate 1142a is separated from the front panel 110, the vertical height of the front panel 110 may be reduced by a length corresponding to a width of the first gap G1 associated with the first cutting plate 1142a. The user may cur the front panel 110 at different cutting grooves 1141 to bend and remove different ones of the cutting plates 1142. Based on the above principle, the user may adjust the vertical height of the front panel 110 by removing one or more of the cutting plates 1142 from the front panel 110.

The cutting groove 1141 may include a first inclined surface 1143. The first inclined surface 1143 may be inclined vertically, and the first inclined surface 1143 may have a first inclination angle 81 with respect to a front-rear direction. The cutting groove 1141 may include a second inclined surface 1144. The second inclined surface 1144 may be inclined vertically, and the second inclined surface 1144 may have a second inclination angle 82 with respect to the front-rear direction. The second inclined surface 1144 may be formed under the first inclined surface 1143.

The cutting groove 1141 may also include a cut surface 1145. The cut surface 1145 may connect the first inclined surface 1143 and the second inclined surface 1144. The cut surface 1145 may be disposed in front of a rear surface of the cutting plate 1142.

The first inclination angle 81 may be greater than 30 degrees. The first inclination angle 81 may be less than 60 degrees. The second inclination angle 82 may be greater than 30 degrees. The second inclination angle 82 may be less than 60 degrees. If the inclination angle 81, 82 of the cutting groove 1141 is less than a predetermined angle (e.g., 30 degrees), the plate 114 may decrease in thickness such that the rigidity of the plate 114 may also decrease. In addition, if the inclination angle 81, 82 of the cutting groove 1141 is greater than a predetermined angle (e.g., 60 degrees), it may be difficult to cut the cutting plate 1142, thereby requiring an excessive force to cut the cutting plate 1142. Accordingly, by optimizing the inclination angles 81, 82 of the cutting groove 1141, the rigidity of the plate 114 may be secured while facilitating cutting of the cutting plate 1142 by a user when bending the cutting plate 1142 at the cutting groove 1141.

A depth t of the cutting groove 1141 may refer to a distance from a rear surface of the plate 114 to the cut surface 1145. The depth t of the cutting groove 1141 may be greater than 1.5 mm. The depth t of the cutting groove 1141 may be less than 2 mm. If the depth t of the cutting groove 1141 is greater than a predetermined size (e.g., 2 mm), the plate 114 decreases in thickness, such that the rigidity of the plate 114 may decrease. In addition, if the depth t of the cutting groove 1141 is less than a predetermined size (e.g., less than 1.5 mm), it is difficult to cut the cutting plate 1142, thereby requiring an excessive force to cut the cutting plate 1142. Accordingly, by optimizing the depth t of the cutting groove 1141, the rigidity of the plate 114 may be secured while facilitating cutting of the cutting plate 1142 by a user.

The front panel 110 may include a reinforcement rib 1191. The reinforcement rib 1191 may protrude rearward from the front panel 110 and may extend in the vertical direction. The reinforcement rib 1191 may be positioned closer to the center line C of the front panel 110 than the edge 119. For example, the reinforcement rib 1191 may be spaced apart from the edge 119. The edge 119 may include a panel side surface 1192, and the panel side surface 1192 may form one side surface of the front panel 110, such that the reinforcement rib 1191 is spaced inward from panel side surface 1192.

The cutting groove 1141 may include an edge groove 1146. The edge groove 1146 may form an end portion of the cutting groove 1141. The edge groove 1146 may be formed by recessing a portion of the edge 119. The edge groove 1146 may include the first and second inclined surfaces 1143 and 1144 and the cut surface 1145.

The cutting groove 1141 may include a rib groove 1147. The rib groove 1147 may be spaced apart from the edge groove 1146. The rib groove 1147 may be formed by recessing a portion of the reinforcement rib 1191. The rib groove 1147 may include the first and second inclined surfaces 1143 and 1144 and the cut surface 1145.

The cutting groove 1141 may include a connection groove 1148. The connection groove 1148 may be formed between the edge groove 1146 and the rib groove 1147. The connection groove 1148 may connect the edge groove 1146 and the rib groove 1147.

The edge groove 1146 may be spaced apart from the panel side surface 1192. A gap D1 may be formed between the edge groove 1146 and the panel side surface 1192. Accordingly, when the front panel 110 is viewed from a lateral side, the cutting groove 1141 may not be seen. For example, the cutting groove 1141 may be covered by the edge 119 and thus may not be seen.

The gap D1 between the edge groove 1146 and the panel side surface 1192 may be greater than 1.2 mm. The gap D1 between the edge groove 1146 and the panel side surface 1192 may be less than 3 mm. If the gap D1 between the edge groove 1146 and the panel side surface 1192 is too large (e.g., more than 3 mm), it may be difficult to cut the cutting plate 1142, such that an excessive force from a user may be required to cut the cutting plate 1142. In addition, if the gap D1 between the edge groove 1146 and the panel side surface 1192 is too small (e.g., less than 1.2 mm), the rigidity of the plate 114 decreases, thereby causing a problem in that the cutting plate 1142 may be cut even when little or no force is inadvertently applied thereto. Further, if the gap D1 is not formed between the edge groove 1146 and the panel side surface 1192 such that the cutting groove 1141 extends to the edge of panel side surface 1192, the cutting groove 1141 may be viewed from the outside of the front panel 110, thereby degrading the appearance of the installation kit 100. Accordingly, by optimizing the gap D1 between the edge groove 1146 and the panel side surface 1192 in the installation kit 100 of the present disclosure, sufficient rigidity may be secured and the plate 114 may be easily cut while maintaining a desirable smooth panel side surface 1192.

The edge groove 1146 and the rib groove 1147 may be spaced apart from each other. A gap D2 may be formed between the edge groove 1146 and the rib groove 1147. The connection groove 1148 may have a length corresponding to the gap D2.

A plurality of rib opening parts 1132 may be spaced apart from each other in an extending direction of the gasket coupling rib 1131. Certain ones of the rib opening part 1132 may be positioned in the first coupling part 115. In another example, other ones of the rib opening part 1132 may be positioned in the second coupling part 116. The rib opening parts 1132 may face the coupling ribs 111. The rib coupling parts 1132 may be formed at positions corresponding to the coupling ribs 111. A fastening member (or fastener) 1112 (see FIG. 14) may pass through the rib opening part 1132 to be fastened to the coupling rib 111.

The support protrusion 112 may face the gasket coupling rib 1131. The support protrusion 112 may be disposed between a pair of the plurality of rib coupling parts 1132. The coupling rib 111 may be disposed between the edge 119 and the gasket coupling rib 1131, and the support protrusion 112 may be disposed between the edge 119 and the gasket coupling rib 1131. In another example, the coupling rib 111 may be disposed between the reinforcement rib 1191 and the gasket coupling rib 1131, and the support protrusion 112 may be disposed between the reinforcement rib 1191 and the gasket coupling rib 1131.

The support rib 117 may be seated on top of the lower support 912 (see FIG. 1) of window frame 91. For example, the support rib 117 may allow the installation kit 100 to be seated on the window frame 91 (see FIG. 1). The above structure allows the support rib 117 to be stably seated on the window frame 91 (see FIG. 1). In addition, by forming the gap G between the support rib 117 and the bottom of the panel lower end 110a, the installation kit 100 may be firmly fixed to the window frame 91 (see FIG. 1). For example, a lower portion of the front panel 110, at which the support rib 117 is disposed, may be force-fitted into or otherwise coupled to the lower support 912 (see FIG. 1) of the window frame 91 (see FIG. 1).
