Description

[Detailed Description of the Invention] This invention relates to an electrical component box having a rain collection function in an indoor unit of an air conditioner.

Generally, in the indoor unit of an air conditioner, rainfall enters through the inlet or outlet provided in the outer cabinet that covers the condenser, so the question is how to protect nearby electrical components from the rain. I've been having a lot of trouble with this.

This invention was made from this point of view, and will be explained in detail below with reference to the embodiments shown in Figs. 1 to 3. 1 is an indoor unit main body of an air conditioner, 2 is a front panel 3a is the left side plate, 3b is the right side plate, 4 is a suction grill formed integrally with the top plate of the front cabinet 2, and 5 is fixed to the front cabinet 2. The air outlet, 6 is an outdoor base with an inverted-shaped cross section and consists of a back plate and a bottom plate, and 7 is a partition plate with an inverted-shaped cross section, which is divided into a heat exchanger chamber 8 and a compressor chamber 9. There is.

10 is a compressor, 11 is a blower electric motor, 12 is a blower,
13a and 13b are L-shaped condensers provided so as to surround the blower 12, 14 is an upper electrical box that is a feature of this invention, and 15 is a lower electrical box.
is fixed to the back plate of the outdoor base 6 with screws.

Reference numeral 16 indicates an upward rib extending upward and formed in a U-shape on the periphery of the electrical product upper box 14; 17 indicates a downward rib extending downward and formed in a U-shape on the periphery of the electrical product upper box 14; 18; 1 is a flat surface of the upper box 14 for electrical components, and 19 is an inclined surface formed on one side of the upper box for electrical components.

Further, the electrical product upper box 14 is larger than the electrical product lower box 15 in both vertical and horizontal dimensions, and the electrical product upper box 14 and the electrical product lower box 15
are connected to a compressor motor operating capacitor 20, a blower, and a temperature switch 21 for regulating motor speed. Electrical components such as a blower motor operating capacitor 22 are clamped and fixed with screws 23.

Since the outdoor unit main body is configured in this way, even if rainwater enters from the suction grille 4, the rainwater will flow through the electrical equipment upper box 1.
Since there is a U-shaped upward rib 16 around the flat part 18, rainfall can be stored on the flat part 18 to some extent, but when the amount of water stored increases, it flows to the slope 19 and the partition plate 7 is formed. It is then poured into the bottom plate of the outdoor base 6.

In addition, even if the outer surface of the upward rib 16 is wetted by the splashing of rain, since the upper electrical product box 14 is larger in both vertical and horizontal dimensions than the lower electrical product box 15, the rain may splash onto the outer surface of the upward rib 16.
The downward rib 17 extending downward is transmitted to the periphery of the electrical component 4, and the electrical components fall directly to the bottom plate of the outdoor base 6 located below, so that the electrical components are not wetted by rain, and the electrical component upper box 14 also serves as a rain collection function. This provides an inexpensive electrical box with fewer parts.
