Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to a cooling system, which has an indoor unit configuration of a heating system consisting of a forced air supply/exhaust type combustion device and a cooling system consisting of an evaporator and a fan. This relates to an air conditioner/heater that has both systems.

[Prior Art] When installing the above-mentioned type of air-conditioning/heating machine, as is well known, the heating system's supply and exhaust pipes, the cooling system's refrigerant pipes and electrical wiring, as well as drain hoses, etc., must be installed through the outer wall, etc. Must be. The supply and exhaust pipe is a member that takes in combustion air from the outside and exhausts combustion exhaust gas to the outside, and most of them are constructed as a single pipe with a double inner and outer structure.
There are two separate refrigerant pipes: an outgoing pipe and a return pipe. Therefore, if these were individually drilled through the wall in Shinto style, the installation work would be difficult and the appearance of the building would be damaged. In this way, technological efforts have been made to pass the supply and exhaust pipes and the cooling system refrigerant piping through a common wall through-hole.

The conventional technology disclosed in the above-mentioned publication or currently practiced is to provide a wind and rain prevention plate or the like in a wall through-hole that is opened to draw out the air supply and exhaust pipe to the outside, and to substantially partition the wall through-hole. With this, a single wall through-hole can be divided into an intake/exhaust pipe and a refrigerant piping outlet for efficient use.

[Problems to be Solved by the Invention] In the above-mentioned prior art, one wall through-hole is simply divided and assigned to the insertion part of the supply/exhaust pipe and the refrigerant pipe, and the configuration is also difficult to understand. Even in Inoue, the supply and exhaust pipes and refrigerant piping are separate, and the wall penetration part of the air conditioner/heater is not structurally well-organized, causing many problems in terms of workability and appearance.

This invention was made to solve these conventional problems, and in terms of form and handling, the wall penetrating parts such as supply and exhaust pipes and refrigerant pipes can be made into a single piece, and the wall penetrating holes can be made into a single piece. The objective is to obtain an air conditioner/heater that is small in size, structurally simple, and has good installation workability and appearance.

[Means for Solving the Problems] The air conditioner according to the present invention has a wall penetrating portion that penetrates the wall of the dual internal and external supply and exhaust pipes that constitute the heating system, and the refrigerant piping and electrical wiring that constitute the cooling system. It has an internal storage part that can store each separately in a non-contact state, and is stored collectively in a wall-through sleeve that can be divided into two in the direction along the center line, and also has a cooling system drain. It is configured to be introduced into the air supply path of the above-mentioned supply and exhaust pipe and drained from the supply and exhaust pipe.

[Function] In this invention, the wall penetrating parts of the supply/exhaust tube, refrigerant piping, and electrical wiring can be accommodated in the wall penetrating sleeve nib in a non-contact state when the wall penetrating sleeve is divided into two. By simply connecting them and attaching them to the wall through-holes drilled in the wall, you can consolidate the wall-penetrating parts of the outdoor drawer member all at once, and the air supply and exhaust pipe also functions as a member for draining condensate, so you can use the drain hose. Since there is no need to draw the drain outside, the size of the wall through hole can be reduced and the structure of the wall through sleeve can be simplified.

[Example code] Each of the drawings shows an embodiment of the present invention.

The two systems of refrigerant piping and electrical wiring 5 are connected to the outdoor unit installed outdoors.
connected through the In other words, the supply/exhaust pipe 2, the refrigerant piping, the electrical wiring 5, and the drain hose 6 are normally extended outdoor members, and any of them must be provided through the wall W, which is referred to in this specification. There is a wall penetration. Each of these wall penetration parts is connected to the drain hose 6.
They are all housed in a wall penetrating sleeve 7 which is inserted and fixed into a round wall penetrating hole I formed in a wall W such as an outer wall. The wall penetrating sleeve 7 consists of a sleeve body 8, a ring-shaped mounting flange 9, and a flange nut 10. The sleeve body 8 is composed of an outer shell 11 that is divided into two parts in the direction along the center line, and a partition wall member 12 that is inscribed within the outer shell 11. The sleeve main body 8 in the joined state is a cylindrical body, and the indoor end has a flange that can be attached to the group 1 size flange 9, and the outdoor outer periphery has a screw that allows the flange nut 10 to be screwed into the sleeve. has been done. The two outer shells 11 are each made of resin and formed in the shape of a semicircular gutter, and one outer shell 11 has an outwardly facing engaging claw 13 on the joint surface, and the other outer shell 11 has an outward engaging claw 13 on the joint surface. Inwardly facing engaging claws 14 are respectively formed in the 1-series engaging claws 1.

The partition wall member 12 is a resin molded product in which a plurality of channel structures each having a C-shaped end face with a part of the outer surface open in the direction of the center line are joined together on the non-open side. The example shown in Fig. 3 has three channel structures joined together on the non-open side, with a channel structure 15 in which the supply and exhaust pipe 2 with the largest diameter is housed in the center of the upper part, and a channel structure 15 on both sides of the lower part. A channel structure 16 with a slightly smaller diameter in which the outgoing pipe 3 is housed, and a channel structure 17 with a slightly larger diameter in which the return pipe 4 is housed are formed. The upper outer shell 11 has a fitting recess 18 inside its joint surface.
is formed, into which a locking portion 19 protruding from a portion of the channel structure 16, 17 of the segmental partition member 12 can be removably fitted. The drain hose 6 is inserted at the base of the supply/exhaust tube 2 into an outer pipe that is an air supply path of the supply/exhaust tube 2, and is configured to allow drainage of drain from the end of the air supply path of the supply/exhaust tube 2. Therefore, the inside of the sleeve main body 8 is divided into a plurality of storage sections parallel to the center line. Although the housing for electrical wiring is not clearly divided, these can be stored in a suitable empty space such as section A in FIG. 3.

That is, first, the wall penetrating portions of the supply/exhaust pipe 2, refrigerant piping, and electrical wiring 5 are placed in predetermined housing portions in the partition wall member 12, and the open portions are used for channel structures 15, 16, 17, etc. Fitting, locking part 1 of partition wall member 12
