Abstract

PURPOSE:To facilitate the design change of an electrical part containing section and at the same time prevent the electrical part containing section from being influenced by an air passage to blow off the air into a room by a structure wherein the electrical part containing section is arranged in an empty space made at one side of a partition plate so as to be in the state separated from the partition plate. CONSTITUTION:An electrical part containing section 29 is arranged in an empty space made at one side of a partition plate 20, which partitions the indoor side of an integral type air conditioner from its outdoor side, so as to be in a state separated from the partition plate 20 in such a manner that the indoor side and the outdoor side are partitioned from each other. Consequently, the design of the electrical part containing section can be changed arbitrarily without changing the designing of the partition plate 20 and a fan casing 23, resulting in facilitating the minor change of electrical parts due to the seriately designing of air conditioning units and, in addition, enabling to utilize the covers of the electrical parts composing of the electrical part containing section to other parts for common use.

[Problem that the invention seeks to solve]

However, in the conventional air conditioner described above, the electrical component storage area including the electrical component mounting frame 12 and the recess 18 is separated by the partition plates 9 and 7.
Since it is constructed integrally using a part of the casing 15, the electrical components including the electrical control means may be partially changed due to the creation of a series of air conditioning units, etc. If it becomes necessary to change the design of the section, the design of the partition plate and casing must also be changed, which is uneconomical and increases costs.

In addition, since the air outlet frame 14 through which cold air flows is placed in contact with or very close to the upper part of the electrical component storage section, the electrical component mounting frame 12 is cooled through this air outlet frame 14, and the surface of the electrical component mounting frame 12 is cooled. Condensation forms. In this case, the dew that has formed on the inner surface of the top plate of the electrical component mounting frame 12 drips onto the electrical components inside, degrading the insulation of the electrical components and impeding the normal operation of the electrical components, and eventually causing the air conditioner to malfunction. This will make driving control impossible.

Therefore, dew condensation can be prevented by pasting a heat insulating sheet on the surface of the electrical component mounting frame 12, especially on the inner surface of the top plate, but the additional process of pasting the heat insulating sheet increases costs. Moreover, because there is uneven adhesion between the top plate and the heat insulating sheet, the heat insulating sheet becomes thinner over time, making it impossible to consistently prevent condensation and maintaining stable quality. there were.

[Purpose of the invention]

This invention was made in order to solve the above-mentioned conventional problems, and it is possible to easily change the design of the electrical component storage section due to a minor change in electrical components without changing the design of the partition plate. It is an object of the present invention to provide an air conditioner that allows components to be used for other purposes and prevents dew from forming on electrical components, etc., without using a heat insulating material.

[Means for solving problems]

In the integrated air conditioner according to the present invention, an empty space is formed on one side of a partition plate that partitions an indoor side and an outdoor side near an indoor heat exchange unit, and an electrical appliance separated from the partition plate is provided in this empty space. This is where a storage section is placed.

[Effect]

In this invention, by arranging the electrical component storage section in an empty space formed on one side of the partition plate and separated from the partition plate, it is easy to change the electrical component storage section, and the electrical component storage section can be connected to an indoor air outlet. Avoid being affected by wind paths.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

Ru.

FIGS. 1 to 3 show an example of the top-blowing integrated air conditioner of the present invention.

An air passage 26 located above the wind tunnel 25 and communicating therewith is formed horizontally, and this air passage 26 communicates with the blow-off hole 22 of the partition plate 20. A blowout guide frame 27 is attached to guide the air pumped by the rotation of the Sirocco 7 ammeter from the blowout hole 22 to the blowout port 19b of the front panel 19.

By making the width dimension of the partition plate 20 shorter than the width dimension d of the base 2, an electrical component storage section 29 is disposed in the empty space 28 formed at one end of the partition plate 20. The electrical component storage section 29 includes an electrical component mounting plate 29a bent into an L shape, and an electrical component cover 2 bent into an L shape.
9b and a top plate 29c, among these components,

The top opening surrounded by 4 is covered by a top plate 38. In addition, in this figure, the same reference numerals as in FIGS. 1 to 3 indicate the same parts.

In the electrical component storage section 29 in the embodiment described above, the same effects as in the case of FIG. 1 can be obtained, and the partition plate 2
By securing an empty space 28 on one side of the 0 and installing the electrical component storage section 29 in this empty space 28 separately from the partition plate 20, the outdoor heat exchange unit 4 side of the electrical component cover With this expansion, the electrical equipment cover can be used as a cover for soundproofing the compressed m5.

Note that the electrical component cover 33 is not limited to being used to obtain the soundproofing effect of the compression m5, and can of course be used for other purposes.

〔Effect of the invention〕

As explained above, according to the present invention, an empty space is formed on one side of the partition plate that partitions the indoor side and the outdoor side of an integrated air conditioner, and the indoor side and the outdoor side are separated in this empty space. Since the electrical component storage section 29 is arranged separately from the partition plate so as to be partitioned, the design of the electrical component storage section can be changed arbitrarily without changing the design of the partition plate and the uncasing 7. Along with this, the air conditioning units have been made into a series, which not only makes it easier to make minor changes to electrical components, but also makes it possible to use them for purposes other than the electrical component covers that make up the electrical component storage area. Furthermore, since the electrical component storage section is reliably separated from the air path side, dew condensation on the electrical component side can be prevented without providing a heat insulating material to the electrical component storage section.
