Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a heat exchange unit that is fixed to a wall hanging board on an indoor wall.

(B) Prior Art Conventionally, as an example of the structure of a heat exchange unit that is fixed to a wall hanging board on an indoor wall, there has been disclosed a structure as shown in Japanese Utility Model Publication No. 1982-19224.

According to this content, a recess is provided on the back side of the main body of the heat exchange unit to accommodate the inter-unit piping led out from the main body. When installing the main unit on an indoor wall with the pipe stored in this recess, hold the pipe stored in the recess in the recess with a pipe holder to prevent the pipe from floating up from the back. The main body was fixed to a wall hanging board on the indoor wall.

(c) Problems that the invention attempts to solve In this way, by storing the piping in the recess of the main body,
When installing this main unit on an indoor wall, please
The main body had to be secured to the wall plate after the pipe was held in the recess with a pipe holder, making the installation process cumbersome.

The purpose of this invention is to make it easier to install the main unit when the piping is stored in a recess, and to prevent drain water that has adhered to the piping and fallen from leaking to the outside of the main unit. This is what I did.

(d) Means for solving the problem In order to achieve this objective, the present invention attaches a pipe holder made of synthetic resin whose tip is fixed to the pipe storage section inside the main body, and also A rising piece is provided at the rear end, and a locking portion for a wall hanging plate is provided on the rear surface of this rising piece, and a rib-shaped reinforcing piece is provided on this pipe holding device to connect the inner surface of the rising piece and the horizontal surface. This is how it was done.

(E) Function The heat exchange unit of the present invention connects the inner surface of the rising piece of the synthetic resin piping holder and the horizontal surface with a rib-shaped reinforcing piece, thereby reinforcing the piping holder. can be temporarily fixed to the storage part of the main body, and this piping holder can be engaged with the wall plate, and by receiving the inter-unit piping with a rib-shaped reinforcing piece, the inter-unit piping and the piping holder can be connected. The contact area between the units is reduced to make it difficult for the heat of the inter-unit piping to be transmitted to the piping holder.

(F) Embodiment In Fig. 1, 1 is an indoor heat exchange unit of a separate air conditioner, 2 is a wall plate fixed to the indoor wall 3, and the upper part (not shown) of this wall plate 2 is heated. The upper part of the exchange unit 1 is engaged. This heat exchange unit 1 is comprised of a main body 4 that is secured to a wall plate 2, and an exterior cover 5 that is attached to the front surface of this main body. A blower 6, a heat exchanger 7, and a drain pan 8 are attached to the main body 4. 9 is a heat insulating material attached to the back surface of the main body 4.

10, the tip 17 is the protruding piece 11 at the bottom of the main body 4.
The presser is screwed onto the holder and is made of synthetic resin.
A rising piece 12 is formed at the rear of this presser 10, and a locking portion 13 extending rearward is formed at the rear surface of this rising piece 12. 14
is from the front surface 15 of this rising piece 12 to the horizontal surface 16
There are four reinforcing pieces connected together as shown in Figure 2. Reference numeral 18 denotes a pressing piece formed on the lower surface of the horizontal plate 19, which is close to the bottom plate 20 of the main body 4.

Reference numeral 21 denotes a pipe storage section surrounded by a heat insulating material 9 and a holding tool 10, in which a refrigerant pipe 23 connected to a drain hose 22 and an outdoor heat exchange unit (not shown) and an inter-unit cord 24 are stored. .

A suction port 25 and a discharge port 26 are formed in the exterior cover 5, the suction port 25 facing the heat exchanger 7, and the discharge port 26 communicating with the ventilation passage 27 of the main body 4. A sealing material 28 is attached to the edge of the bottom plate 20 of the main body 4, and is used to block drain water flowing into the bottom plate 20 and allow it to evaporate naturally. This main body 4 is made of resin and has elastic force, and when the bottom plate 20 is pushed upward by hand from below (in the direction of the solid line arrow in Figure 3), the bottom plate 20 moves upward and is pressed by the bottom plate 20. The piece 18 is pressed so that the presser foot 10 can be moved upward.

When installing such a heat exchange unit 1, the wall hanging plate 2 is first attached to the indoor wall surface 3. On the other hand, the drain hose 2 is installed in the pipe storage section 21 of the main body 4.
2. Store the refrigerant pipe 23 and the inter-unit cord 24. At this time, since the rising piece 12 of the presser 10 extends upward, it becomes difficult for the refrigerant pipe 23 to come out from this storage part. Further, the refrigerant pipes 23 are placed on the reinforcing piece 14, and the contact area between these pipes 23 and the presser 10 is made small to make it difficult for the heat of these pipes 23 to be transmitted to the presser 10.
Moreover, this reinforcing piece 14 allows the flat presser 10 to be
is reinforced, and the weight of these pipes 23 causes the presser 10 to
makes it difficult to bend. Further, some of the drain water that has adhered to and dripped onto these pipes is received between 29 between the reinforcing pieces 14 of the presser 10 (see FIG. 2).

When the upper part of the main body 4 is engaged with the wall-hanging plate 2, the presser 10 approaches the lower part 30 of the wall-hanging plate 2. When the bottom plate 20 is pushed upward in this state, the bottom plate 20 bends upward as shown in FIG. The locking portion 13 moves along the slope 31 of the lower portion 30 and fits into the engagement hole 32 (see FIG. 4).

(g) Effects of the invention As described above, according to the invention, the inner surface of the rising piece of the synthetic resin pipe holder attached to the pipe storage section of the main body and the horizontal surface are connected by a rib-shaped reinforcing piece. The piping holder is less likely to bend due to the weight of the piping, allowing the piping to be placed at a predetermined location on the main body. In addition, the edge of the rib-shaped reinforcing piece receives the pipe to reduce the contact area between the pipe and the pipe holder, making it difficult for the heat of the pipe to be transferred to the pipe holder, which prevents dew from adhering to the wall of the main body. This can reduce the risk.
