[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] For a ceiling-embedded indoor unit, a housing forming an outer shape thereof is in a box shape having a side wall portion and an upper surface wall portion. Also, a heat insulating member disposed in the housing is also in a box shape having a side wall portion and an upper surface wall portion. However, in a case where the heat insulating member is transported as a part by, for example, a truck or the like, in a case where there is a height limitation in a vehicle cabin, a container, or the like, it is desirable to transport by stacking as many heat insulating members as possible to reduce transportation costs. However, with the heat insulating member in a box shape, the height of the load increases in correspondence with the amount of increase in the height of the heat insulating member for each increase in the number of stacked heat insulating members. Therefore, for a heat insulating member in a box shape, it is not easy to increase the number of stacked heat insulating members, and thus, it is difficult to achieve a reduction in transportation costs.

[0008] Therefore, the present embodiment provides a technical solution relating to an indoor unit of an air conditioner provided with a heat insulating member in a box shape having a side wall portion and an upper surface wall portion, and a heat insulating member in a box shape provided to an indoor unit of an air conditioner, which can suppress the height in a case where a plurality of heat insulating members are stacked.

[0009] SOLUTION TO THE PROBLEM

[0010] The indoor unit of the air conditioner according to the present embodiment includes a housing having a side wall portion and an upper surface wall portion, a thermal insulation member having a thermal insulation side wall portion along the side wall portion of the housing and a thermal insulation upper surface wall portion along the upper surface wall portion of the housing, and an insertion portion formed at a corner portion of the thermal insulation side wall portion and the thermal insulation upper surface wall portion, into which a portion of another thermal insulation member is inserted.

[0011] The thermal insulation member according to the present embodiment is a thermal insulation member provided in an indoor unit of an air conditioner having an outer shape formed by a housing having a side wall portion and an upper surface wall portion, and includes a thermal insulation side wall portion along the side wall portion of the housing and a thermal insulation upper surface wall portion along the upper surface wall portion of the housing, and an insertion portion formed at a corner portion of the thermal insulation side wall portion and the thermal insulation upper surface wall portion, into which a portion of another thermal insulation member is inserted.

[0023] An embodiment of an indoor unit of an air conditioner and a heat insulating member will be described below with reference to the drawings. Figure 1 The illustrated indoor unit 10 of the air conditioner is an indoor unit that is buried in a ceiling of a room that is a space to be air-conditioned, that is, a so-called ceiling-buried indoor unit. The indoor unit 10 has a casing 11 and a decorative panel 12. The casing 11 is inserted from the indoor side into a rectangular opening portion (not shown) provided in the ceiling. Further, the casing 11 is fixed in a state of being suspended from the back surface of the ceiling by a suspension bolt or the like (not shown). The decorative panel 12 is installed below the casing 11 in a state of being exposed to the indoor side.

[0024] The decorative panel 12 is formed in a substantially rectangular plate shape. An air suction port 13 and an air blow port 14 are provided in the decorative panel 12. The air suction port 13 is formed in a substantially square shape in a central portion of the decorative panel 12. The air suction port 13 is configured to be a so-called suction grille that is opened in a lattice shape in a ventilating manner. The air blow port 14 is formed in a long strip shape along each side of the air suction port 13. A louver 14a that adjusts the direction of air blown out from the air blow port 14 is rotatably provided in the air blow port 14.

[0025] As Figure 2 illustrated, the casing 11 forms the outer shape of the upper surface and the side surface in the indoor unit 10. The casing 11 is in a box shape having a side surface wall portion 11a, an upper surface wall portion 11b, and a lower surface opening portion 11c. The side surface wall portion 11a is provided in a wall shape so as to close the side surface of the casing 11. The upper surface wall portion 11b is provided in a wall shape so as to close the upper surface of the casing 11. The lower surface opening portion 11c is opened in a substantially rectangular shape so as to open the lower surface of the casing 11. The decorative panel 12 covers the lower surface opening portion 11c of the casing 11 from below. A blower fan 15, a heat exchanger 16, and the like are accommodated in the casing 11.

[0026] A blower 15 is disposed in the central part of the housing 11. Furthermore, the blower 15 is disposed above the air intake 13. A heat exchanger 16 is disposed around the blower 15. Additionally, the heat exchanger 16 is disposed in the upper part between the air intake 13 and the air outlet 14 in the decorative panel 12. The heat exchanger 16, together with a compressor (not shown) and an outdoor heat exchanger, constitutes a known refrigeration cycle, capable of heating and cooling the air.

[0027] like Figure 2 As illustrated by the dashed arrow W, the indoor unit 10 draws in indoor air through the air intake 13 by driving the fan 15, exchanges heat with the drawn-in air through the heat exchanger 16, and blows the heat-exchanged air out through the air outlet 14. Thus, the indoor unit 10 can perform air conditioning control to adjust the indoor temperature to a predetermined set temperature.

[0028] Furthermore, the indoor unit 10 has a drain pan 17 within the housing 11. The drain pan 17 is disposed between the decorative panel 12 and the heat exchanger 16. The drain pan 17 is arranged to fill the upper portion between the air intake 13 and the air outlet 14. The drain pan 17 collects condensate generated from the heat exchanger 16 below the heat exchanger 16.

[0029] Furthermore, the indoor unit 10 includes a heat insulation component 100 within its housing 11. The heat insulation component 100 is formed, for example, of a material with heat insulation properties such as expanded polystyrene foam. Figure 3 and Figure 4 As illustrated, the heat insulation member 100 has a box-shaped form with a heat-insulating side wall portion 100a, a heat-insulating upper surface wall portion 100b, and a heat-insulating lower surface opening portion 100c. The heat-insulating side wall portion 100a is configured as a wall to close the sides of the heat insulation member 100. The heat-insulating upper surface wall portion 100b is configured as a wall to close the upper surface of the heat insulation member 100. The heat-insulating lower surface opening portion 100c is a generally rectangular opening to open the lower surface of the heat insulation member 100.

[0030] In addition, the name "heat insulation lower surface opening 100c" refers to the name of the opening provided in the heat insulation component 100, and does not refer to the heat insulation performance of the heat insulation lower surface opening 100c.

[0031] In a state where the heat-insulating member 100 is arranged in the housing 11, the outer surface of the heat-insulating side surface wall portion 100a is arranged in a manner to follow the inner surface of the side surface wall portion 11a of the housing 11. Further, in a state where the heat-insulating member 100 is arranged in the housing 11, the outer surface of the heat-insulating upper surface wall portion 100b is arranged in a manner to follow the inner surface of the upper surface wall portion 11b of the housing 11. Further, in a state where the heat-insulating member 100 is arranged in the housing 11, the heat-insulating lower surface opening portion 100c of the heat-insulating member 100 is arranged inside the lower surface opening portion 11c of the housing 11.

[0032] A cutout portion 101 is formed in a part of the lower end portion of the heat-insulating member 100. The cutout portion 101 is cut in a substantially trapezoidal shape in which the lower side is longer than the upper side. A portion of the heat-insulating member 100 other than the cutout portion 101 remains as a wall portion 102. In other words, the wall portion 102 extends downward in a manner to fill in between the cutout portions 101. Further, the wall portion 102 extends downward from the height position of the upper end of the cutout portion 101.

[0033] Further, the heat-insulating member 100 is configured so that an embedded step portion 103 is formed in a corner portion formed by the heat-insulating side surface wall portion 100a and the heat-insulating upper surface wall portion 100b. The embedded step portion 103 is an example of an embedded portion. The embedded step portion 103 is located above the wall portion 102. That is, the heat-insulating member 100 is configured so that the wall portion 102 and the embedded step portion 103 are formed in pairs in the up-down direction. Further, the embedded step portion 103 extends in a direction orthogonal to the height direction of the heat-insulating member 100.

[0034] As Figure 5 illustrated, the embedded step portion 103 is in a shape recessed in a manner to form a step toward the inside of the heat-insulating member 100. Further, the thickness D1 of the portion of the heat-insulating member 100 in which the embedded step portion 103 is formed and the thickness D2 of the portion of the heat-insulating member 100 other than the embedded step portion 103 are the same thickness, completely or almost. That is, the heat-insulating member 100 is configured so that the portion in which the embedded step portion 103 is formed is not thinner than the portion other than the embedded step portion 103. The portion of the heat-insulating member 100 other than the embedded step portion 103 is, for example, a portion in which the heat-insulating side surface wall portion 100a is formed or a portion in which the heat-insulating upper surface wall portion 100b is formed. Further, the inner surface N of the portion of the heat-insulating member 100 in which the embedded step portion 103 is formed is not in a stepped shape according to the shape in which the embedded step portion 103 is recessed, but is in a smooth curved surface shape.

[0035] Further, the recessed amount A of the embedded step portion 103 is a recessed amount taking into account the thickness of the lower end portion of the heat-insulating member 100 and the thickness of a part of the drain pan 17. That is, as Figure 6As illustrated, an extension wall portion 17a extending upward is provided at a corner portion of the drain pan 17. The cutout portion 101 of the thermal insulation member 100 has a shape corresponding to the shape of the extension wall portion 17a. Therefore, as illustrated, the extension wall portion 17a is fitted in the cutout portion 101 of the thermal insulation member 100 in a state where the drain pan 17 is assembled to the thermal insulation member 100. Figure 7 As illustrated, in a state where the drain pan 17 is assembled to the thermal insulation member 100, the extension wall portion 17a is fitted in the cutout portion 101 of the thermal insulation member 100.

[0036] Further, as illustrated, in a state where the drain pan 17 is assembled to the thermal insulation member 100, the outer surface of the extension wall portion 17a and the outer surface of the thermal insulation side wall portion 100a are entirely or substantially the same plane. Figure 7

[0037] As illustrated, in a state where the drain pan 17 is assembled to the thermal insulation member 100, the extension wall portion 17a is fitted in the cutout portion 101 of the thermal insulation member 100. Figure 8 Figure 9 As illustrated, in a case where the thermal insulation member 100 is transported as a part by, for example, a truck or the like, a plurality of thermal insulation members 100 are stacked in the up-down direction. In this case, the thermal insulation members 100 are not stacked with the open thermal insulation lower surface opening portion 100c as the lower side, but are stacked with the closed thermal insulation upper surface wall portion 100b as the lower side. By taking the closed thermal insulation upper surface wall portion 100b as the lower side, the thermal insulation members 100 can be stacked in a stable state compared to a case where the open thermal insulation lower surface opening portion 100c is taken as the lower side.

[0038] Further, in a case where a plurality of thermal insulation members 100 are stacked, a state is obtained in which the wall portion 102 of the thermal insulation member 100 on the lower side is fitted in the fitting step portion 103 of the thermal insulation member 100 on the upper side, and the thermal insulation upper surface wall portion 100b of the thermal insulation member 100 on the upper side is accommodated in the thermal insulation lower surface opening portion 100c of the thermal insulation member 100 on the lower side. Therefore, as illustrated, the height Ha in a case where a plurality of thermal insulation members 100 are stacked can be suppressed to be lower than the height Hz in a case where the conventional box-shaped thermal insulation member Z, that is, a thermal insulation member Z not having a constituent element corresponding to the fitting step portion 103 of the present disclosure, is stacked. Figure 10

[0039] That is, according to the thermal insulation member 100, the fitting step portion 103 functions as a so-called "overlapping portion". Therefore, according to the thermal insulation member 100, even in a case where the height of, for example, a truck or the like is a constraint, the number of stacked thermal insulation members 100, that is, the number of thermal insulation members 100 that can be transported at a time, can be increased. Thus, according to the thermal insulation member 100 of the present disclosure, compared to a case where the conventional thermal insulation member Z is transported, reduction of transportation cost can be achieved.

[0040] Further, as illustrated, in a case where the thermal insulation member 100 is transported as a part by, for example, a truck or the like, a plurality of thermal insulation members 100 are stacked in the up-down direction. In this case, the thermal insulation members 100 are not stacked with the open thermal insulation lower surface opening portion 100c as the lower side, but are stacked with the closed thermal insulation upper surface wall portion 100b as the lower side. By taking the closed thermal insulation upper surface wall portion 100b as the lower side, the thermal insulation members 100 can be stacked in a stable state compared to a case where the open thermal insulation lower surface opening portion 100c is taken as the lower side. Figure 11 ​​​As illustrated, in a state in which a plurality of the thermal insulation members 100 are stacked, the cutout portion 101 of the lower thermal insulation member 100 is not completely buried, and becomes a state in which the opening K is formed in a part thereof. That is, the length of the embedded step portion 103 in the height direction of the thermal insulation member 100 becomes a length to the extent that, in a state in which a plurality of the thermal insulation members 100 are stacked, not the entire wall portion 102 of the lower thermal insulation member 100 is embedded, but only a part of the wall portion 102 of the lower thermal insulation member 100, in this case, a part that becomes the upper side in the stacked state, is embedded.

[0041] Therefore, according to the thermal insulation member 100 of the present disclosure, in a state in which a plurality of the thermal insulation members 100 are stacked, it is possible to form the opening K in the cutout portion 101 of the lower thermal insulation member 100. Also, for example, when the worker detaches the upper thermal insulation member 100 from the lower thermal insulation member 100, by inserting a finger into the opening K, it is possible to easily lift and separate the upper thermal insulation member 100 from the lower thermal insulation member 100. That is, the opening K can be used as a so-called "handle".

[0042] Further, the embedded step portion 103 is a shape that is recessed toward the inside of the thermal insulation member 100, but the thickness of the portion of the thermal insulation member 100 in which the embedded step portion 103 is formed is completely or approximately the same as the thickness of the portion of the thermal insulation member 100 other than the embedded step portion 103. Therefore, even if a part of the thermal insulation member 100 is recessed toward the inside to form the embedded step portion 103, it is possible to avoid a decrease in the thermal insulation performance or strength of the portion in which the embedded step portion 103 is formed and the surrounding portion.

[0043] Further, the embedded step portion 103 is a shape that is recessed toward the inside of the thermal insulation member 100, but the inner surface N of the portion of the thermal insulation member 100 in which the embedded step portion 103 is formed does not become a stepped shape according to the shape in which the embedded step portion 103 is recessed, but is formed as a smooth curved surface. Thereby, even if a part of the thermal insulation member 100 is recessed toward the inside to form the embedded step portion 103, it is possible to make the flow of air on the inside of the portion in which the embedded step portion 103 is formed smooth, and it is possible to avoid a disorder, weakening, or obstruction of the flow of air. Therefore, even if the thermal insulation member 100 is formed with the embedded step portion 103, it is possible to avoid a decrease in the air supply performance of the indoor unit 10.

[0044] In addition, the present embodiment is not limited to the above-described embodiment, and various modifications, extensions, and the like can be made within the scope of the gist thereof. For example, as long as the configuration is such that at least a part of the lower heat insulating member 100 can be fitted, the position, size, amount of recess, length, and the like of the fitting step portion 103 in the heat insulating member 100 can be appropriately changed and implemented. That is, as long as the fitting step portion 103 is a configuration in which a wall portion 102 or a portion other than the wall portion 102 of another heat insulating member 100 can be fitted, the configuration can be appropriately changed and implemented. In addition, the portion of the heat insulating member 100 in which the fitting step portion 103 of another heat insulating member 100 is fitted is preferably a portion of the lower side of the heat insulating member 100 as much as possible.

[0045] Further, the fitting portion can not be a shape in which a step is formed toward the inner side of the heat insulating member 100, but can be, for example, a shape in which a smooth recess is formed toward the inner side of the heat insulating member 100, and the like.

[0046] The above-described embodiments relating to the present application have been described, but these embodiments are merely presented as examples and are not intended to limit the scope of the application. These new embodiments can be implemented in various other ways, and various omissions, substitutions, modifications, and the like can be made within the scope of the gist of the application. The present embodiment and its modifications are included in the scope and gist of the application, and are included in the scope of the application and its equivalents described in the claims.
