Description

[Detailed description of the invention] [Technical field of the invention] This invention relates to a separate type air conditioner in which an indoor unit and an outdoor unit are separated, and in particular, the invention relates to a separate air conditioner in which an indoor unit and an outdoor unit are separated. This invention relates to the mounting structure of a heat insulating case covering a packed valve.

[Technical background of the invention and its problems]

Generally, a separate air conditioner has an indoor unit and an outdoor unit installed separately, and the two units are connected by a connecting pipe equipped with a packed valve. The packed valve is attached to the unit casing of the outdoor unit from the outside and protrudes outward from the unit casing in order to facilitate the attachment and detachment of connecting piping. For this reason, the sealed valve can be easily touched by a person from the outside, but on the other hand, the inside of the connecting pipe becomes hot during heating operation, so there is a risk of burns.

Furthermore, during cooling operation, the pressure inside the connecting pipes becomes low, so dew adheres to them. As the cooling operation continues, the dew adhering to the connecting pipes gradually grows, and the amount of adhesion gradually increases. For this reason, when the outdoor unit of an air conditioner is attached to the wall of a house or installed on the balcony of a high-rise residential building, water droplets adhering to the sealed valve will drip outside and hit people, laundry, etc. There was a risk of contamination.

In addition, the packed valve that protrudes from the unit casing of the outdoor unit is usually made of brass, and because it is attached to the outdoor unit that is exposed to the wind and rain, it may gradually discolor and become unsightly, or if you step on the packed valve. There were cases where people were hit and injured.

[Purpose of invention]

This idea was created in consideration of the above-mentioned circumstances, and by covering the sealed valve with an insulating case, it not only improves aesthetics but also prevents dew from dripping during cooling operation and ensures human body protection during heating operation. The purpose is to provide an air conditioner with

[Summary of the idea]

In order to achieve the above-mentioned object, this invention is a separate type air conditioner in which a packed valve is provided in the connecting pipe connecting an indoor unit and an outdoor unit. A heat insulating case is attached to the unit casing of the outdoor unit from the outside.

[Example of idea]

Hereinafter, embodiments of this invention will be described with reference to the accompanying drawings.

In FIG. 1, reference numeral 10 indicates a connection pipe that connects an indoor unit and an outdoor unit of a separate air conditioner, and a packed valve 11 is provided in the middle of this connection pipe 10 so as to be freely insertable and removable. The packed valve 11 is housed in a box-shaped heat insulating case 12 and is thermally shielded from the outside.

The insulation case 12 is made of closed cell foam resin material.
For example, it is constructed by using polyethylene as a material and molding it. The heat insulating case 12 is divided into upper and lower halves, an upper case element 13a and a lower case element 13b, which are connected by a hinge joint 13.
c, and recesses 14 and 15 for housing packed valves are formed inside. The packed valve 11 is attached to a unit casing 16 (see FIGS. 3 to 5) of the outdoor unit, attached to a fixing plate 17 with a fitting 18, and covered with a heat insulating case 12.

A drain guide 20 extends to one side from the packed valve housing recess of the heat insulating case 12.
The drain guide 20 extends into the unit casing 16 of the outdoor unit through a guide groove 21 formed in the fixed plate 17, and guides the drain accommodated in the packed valve housing recesses 14 and 15 into the unit casing 16. , preventing it from being dissipated to the outside.

On the other hand, a pipe insertion hole 23 through which the connecting pipe 10 passes is formed in the upper case element 13a of the heat insulating case 12. The pipe insertion hole 23 has a hole diameter larger than the diameter of the connecting pipe 10, so that the connecting pipe 10
is loosely fitted into the pipe insertion hole 23. Further, a slit 24 is formed in the upper case element 13a to allow the connecting pipe 10 to be inserted into and removed from the pipe insertion hole 23. The slit 24 is located in the upper case element 13a.
It extends toward the pipe insertion hole 23 from one side. At that time, since the heat insulating case 12 is made of a soft closed-cell foam material, it is easily deformed, and the pipe insertion hole 2 of the upper case element 13a
This makes it easier to push the connecting pipe 10 into 3. After the connecting pipe 10 is pushed in, the elastic holding force of the slit 24 prevents the heat insulating case 12 from coming off.

After the packed valve 11 is covered with the heat insulating case 12 in this manner, the heat insulating case 12 is covered with a box-shaped case cover 25 made of a resin material such as plastic. The case cover 25 has an opening on one side, and is attached to the heat insulating case 12 through this opening. During installation, the connection pipe 10 is guided to be inserted into the pipe insertion hole 27 via an insertion guide 26 formed at the top, and is loosely fitted into the pipe insertion hole 27. case cover 25
can be transparent or colored, and the color is appropriately selected according to the design of the unit casing 16 of the outdoor unit. Specifically, the insulation case 12
When the color of the heat insulating case 12 is emphasized, the case cover 25 is made transparent, and when it is not desired to show the color of the heat insulating case 12, it can be a colored cover.
The color is selected in consideration of the contrast with 6, the connecting pipe 10, or the house.

Next, the insulation case 12 and the case cover 25
The installation procedure will be explained with reference to FIGS. 3 to 5.

After installing the indoor and outdoor units of the air conditioner, connect the packed valve 1 between these units.
Connect with the connecting pipe 10 with 1. At this time, the connecting pipe 10 is covered with a highly flexible pipe heat insulating material 28 such as sponge.

After that, attach the insulation case 1 to the packed valve 11.
Attach 2. When installing the heat insulating case 12, the pipe heat insulating material 28 of the connecting pipe 10 is previously displaced upward by a distance L, for example 50 mm, or cut and adjusted. After this adjustment, the lower case element 13b is applied from below the packed valve 11, and the drain guide 20 protruding from the lower case element 13b is inserted into the unit casing 16 of the outdoor unit through the guide groove 21 of the valve fixing plate 17. insert. Thereafter, the upper case element 13a is folded up via the hinge joint 13c. By this folding, the upper case element 13a
The connecting pipe 10 is guided into the slit 24 and relatively pushed into the pipe insertion hole 23. By pushing the connecting pipe 10 into the pipe insertion hole 23 and loosely fitting it, the packed valve 11 is inserted into the insulation case 1.
Covered by 2. Thereafter, the insulating case 12 may be pre-colored in a color that matches the design of the unit casing 16.

Next, the case cover 25 is inserted into the heat insulating case 12, and the case cover 25 is attached to the heat insulating case 12. When inserting the case cover 25, the piping guide part 26 is pulled up to guide the connecting pipe 10, and after insertion, the piping guide part is pulled down to set the case cover 25 so that it does not come off easily.
After this setting, the piping insulation material 28 is pulled down and adjusted so that the gap between the packed valve 11 and the insulation case 12 becomes smaller. At that time, in order to eliminate gaps, the gaps between the connecting pipes may be covered with mounting tape or the like.

By attaching the heat insulating case 12 and the case cover 25, the packed valve 11 is covered in a heat insulating manner. When the air conditioner is operated in this state, the inside of the connecting pipe 10 connected to the outdoor unit becomes a low pressure side, and dew adheres to the connecting pipe 10 and the packed valve 11, and the attached dew gradually grows and becomes water droplets. The water is guided through the connecting pipe 10 into the packed valve storage recesses 14 and 15 of the heat insulating case 12, and the water droplets (drain) guided into the recess 15 are then passed through the drain guide 20 and into the unit casing 16 of the outdoor unit. guided by. Therefore, water droplets generated in the connecting pipes will not scatter around and stain the human body or laundry.

Furthermore, during heating operation, the packed valve 11 attached to the unit casing 16 of the outdoor unit becomes hot, but in this case, by covering the packed valve 11 with the heat insulating case 12, the packed valve 11 can be thermally isolated from the surroundings. can. Therefore, the high temperature of the packed bulb will not cause burns to the human body, and by covering the packed bulb 11 with a highly elastic heat insulating case, injury to humans can be prevented.

In one embodiment of this invention, an example was described in which a packed valve was covered with a heat insulating case and then a case cover was attached to the heat insulating case.
A case cover is not necessarily required. If the case cover is not required, it is necessary to fix the upper and lower case elements 13a and 13b of the heat insulating case with a connecting device such as a connecting wedge 30 shown in FIG. 6 or a band 31 shown in FIG. 7. .

Further, the heat insulating case does not necessarily need to connect the case elements with a hinge joint, and may have a structure in which each case element is made independent.

Furthermore, when a plurality of packed valves are arranged in parallel, the recesses for storing packed valves formed in the heat insulating case may be formed independently.
They may be formed in common, or if the recesses are made independent, guide grooves or holes may be formed to allow the recesses to communicate with each other.

[Effect of idea]

As described above, in the air conditioner according to this invention, the packed valve is covered with a divisible heat insulating case, and this heat insulating case is attached to the unit casing of the outdoor unit from the outside. is blocked. Therefore, even if the packed valve becomes hot during heating operation, there is no risk of people getting burned, and it is safe, and since the packed valve is covered with a heat insulating case, the packed valve is not exposed to the outside. Therefore, even if the packed bulb becomes discolored due to aging, the aesthetic appearance will not be impaired. In particular, the aesthetic appearance can be improved if the insulating case is colored to match the unit casing of the outdoor unit.

In addition, during cooling operation, if water droplets adhering to the connecting pipes are guided into the insulating case, and the water droplets accumulated in the insulating case are guided into the unit casing of the outdoor unit via the drain guide, the water droplets Since it does not scatter outside, there is no risk of staining laundry or clothes.

Furthermore, by covering the packed valve with a heat insulating case, it is safe and will not be injured even if you trip over it, and the heat insulating case can be easily inserted and removed from the packed valve, so it is easy to maintain and maintain.
During service, the insulation case can be easily removed and the packed valve can be easily adjusted.
