Description

The present invention relates to an outdoor unit of an air conditioner that has a handle portion on its top plate.

Conventionally, in this type of product, in which a handle was formed on the top plate, the top plate was placed so as to cover the upper side of the side plate, and screws were screwed on both sides of the handle. There was an outdoor unit of an air conditioner that was fixed to the face plate so that a worker could carry it by holding the handle. (For example, Patent Document 1)

Patent No. 5131207

However, with this conventional model, when water is sprayed near the handle of the outdoor unit due to strong wind and rain, there is nothing between the handle and the side plate to prevent water from entering the outdoor unit. As a result, water could enter the outdoor unit from between the handle and the side panel, and there was a risk that electrical components installed inside the outdoor unit would get wet and malfunction.
As a means to prevent this, it is conceivable to install a sealing material or the like to prevent water intrusion between the handle portion and the side plate, but this increases the number of manufacturing steps for the outdoor unit and increases costs.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an outdoor unit for an air conditioner that can prevent water from entering between the handle and the side plate without increasing the number of manufacturing steps or increasing costs.

In order to solve the above problem, in claim 1 of the present invention, a side plate disposed on a side surface,
an inner extending portion formed at the upper end of the side plate and extending inward;
an upwardly extending portion formed at the inner end of the innerly extending portion and extending vertically upward;
an inner bent portion formed at the upper end of the upwardly extending portion and bent inward;
a top plate that covers above the side plate;
an outer bent portion formed on the top plate and bent along the inner bent portion;
a handle portion formed to protrude outward from the side plate from the lower end of the outer bent portion;
A convex portion protruding outward is formed between the upwardly extending portion covered by the handle portion and the inner bent portion, and the convex portion is configured to abut against the upper end of the handle portion. The inner bent part and the outer bent part are formed along the upper end of the inner bent part, and the inner bent part and the outer bent part are in contact with each other at the upper end of the inner bent part .

According to this invention, since the convex portion projecting outward is formed between the upwardly extending portion covered by the handle portion and the inner bent portion, a sealing material or the like is provided between the handle portion and the side plate. Since the intrusion of water can be prevented without the need for any installation, it is possible to prevent electrical components installed in the outdoor unit from getting wet without increasing the number of manufacturing steps or increasing costs.

Please refer to FIG. 1 is an outdoor unit of an air conditioner, and is a box-shaped housing. The outdoor unit 1 includes a front plate 2 placed on the front, a top plate 3 placed on the top, a side plate 4 placed on the side, and a bottom plate (not shown) placed on the bottom.

The back side of the outdoor unit 1 is open, and an outdoor heat exchanger (not shown) is installed facing the opening. The interior of the outdoor unit 1 is divided by a partition plate (not shown) into a ventilation chamber in which a blower fan is installed and a machine room in which a compressor etc. are installed, with the right side plate 4 facing the machine room. There is.

Please refer to FIG. Reference numeral 5 includes a terminal block (not shown) installed on the right side panel 4 to which a plurality of contact wires are connected, and a valve located below the terminal block to which refrigerant piping (not shown) extending in and out of the outdoor unit 1 is connected. This is a valve cover containing a valve mounting plate and a valve mounting plate.

The refrigerant piping extending to the outside of the outdoor unit 1 is connected to an indoor heat exchanger in the indoor unit (not shown), and the refrigerant piping extending to the inside of the outdoor unit 1 is connected to the interior of the outdoor unit 1 via a compressor and an expansion valve (not shown). Connected to outdoor heat exchanger.
Therefore, when a cooling operation for cooling the room is instructed by a remote controller (not shown) or the like, low-temperature refrigerant flows in the refrigerant pipes and cool air is blown out from the indoor unit, thereby making it possible to cool the room.
Further, when a heating operation for warming the room is instructed by a remote control or the like, high-temperature refrigerant flows in the refrigerant pipe and hot air is blown out from the indoor unit, thereby making it possible to heat the room.

Next, the detailed structure of the top plate 3 will be explained.
Please refer to FIGS. 2 to 6. 3a is an outer bent portion formed at the left and right ends of the top plate 3 and bent downward at a predetermined curvature; 3b is a downward extending portion extending downward from the lower end of the outer bent portion 3a; and 3c is the downward extending portion. This is a screw hole that penetrates through the portion 3b and into which a screw can be screwed, and when the downwardly extending portion 3a is placed on the inner side extending portion 4a of the side plate 4, which will be described later, the upper side of the side plate 4 is covered. The top plate 3 is attached as shown in FIG.

Next, the detailed structure of the upper end portion of the side plate 4 will be explained.
Please refer to FIGS. 3 to 6. 4a is an inner extending portion formed at the upper end of the side plate 4 and extends inward (to the left); 4b is an upward extending portion extending vertically upward from the inner end of the inner extending portion 4a; and 4c is an upward extending portion. An inner bent portion 4d formed at the upper end of the portion 4b and bent inward at a predetermined curvature is a screw hole formed to penetrate the upwardly extending portion 4b.

When attaching the top plate 3 to the side plate 4, the downward extending portion 3b of the top plate 3 is placed on the inner extending portion 4a of the side plate 4, and the screw hole 3c of the top plate 3 and the screw hole of the side plate 4 are placed. The top plate 3 is fixed to the side plate 4 by screws screwed into the top plate 4d.

Next, the handle portion 6 formed on the top plate 3 will be explained.
Please refer to FIGS. 2 to 5. Reference numerals 6 denote handles provided at left and right positions of the top plate 3, respectively. The handle portion 6 is formed to protrude from the lower end of the outer bent portion 3a of the top plate 3 in the outer direction (left and right direction) than the side plate 4, and to be inclined downward with respect to the horizontal direction. The lower end 6a of the handle portion 6 is bent into a substantially U-shaped cross section when viewed from the front, so that the end surface is not exposed at the lower end 6a.
Thereby, when the operator grasps the handle portion 6 and lifts it up, it is possible to prevent the operator from getting his or her hand caught on the rough end surface in the exposed state and injuring his or her hand.

Further, the front and rear ends of the handle portion 6 connected to the top plate 3 are formed to be inclined downward in the front and rear width direction at a predetermined angle, and reach the lower end of the downwardly extending portion 3b of the top plate 3. When viewed from the side, it almost looks like a square.
As a result, compared to the case where the front and rear ends of the handle part 6 are not inclined downward in the width direction of the front and back, the strength of the handle part 6 is improved by making the connection surface with the top plate 3 larger, and the strength of the handle part 6 is improved. Damage due to load being applied to the handle portion 6 during transportation can be prevented.

Next, a structure for preventing water from entering the outdoor unit 1 from the handle portion 6 will be described.
See Figures 3, 4 and 5. Reference numeral 4e denotes a convex portion that is located between the upwardly extending portion 4b and the inner bent portion 4c and is formed to protrude outward (rightward). The convex portion 4e is in contact with the upper end 6b of the handle portion 6, which is bent outward from the lower end of the outer bent portion 3a.
The inner bent portion 4c of the side plate 4 is formed with a curvature that contacts the outer bent portion 3a near the upper end.

Therefore, when water is sprayed onto the handle part 6 due to strong wind and rain, etc., the convex part 4e is in contact with the upper end 6b of the handle part 6, so that the water will not flow between the outer bent part 3a and the inner bent part 4c. It can prevent intrusion.
Furthermore, even if water enters from between the convex portion 4e and the upper end 6b, since the vicinity of the upper end of the inner bent portion 4c is in contact with the outer bent portion 3a, water can be prevented from entering earlier. Therefore, it is possible to reliably prevent water from entering the interior of the outdoor unit 1 and electrical components installed inside the outdoor unit 1 becoming wet and malfunctioning.

Further, the front and rear ends of the convex portion 4e are formed to be inclined downward in the front and rear width direction at the same angle as the front and rear ends of the handle portion 6, and the convex portion 4e extends along the upper end 6b of the handle portion 6. It is formed.
Therefore, since the entire upper end 6b of the handle part 6 is in contact with the convex part 4e, water can be prevented from entering the interior of the outdoor unit 1 at any part of the handle part 6.

Next, the effects of the present invention will be explained.

See FIG. 5. When the top plate 3 is placed on the side plate 4, a convex portion 4e that comes into contact with the upper end 6b of the handle portion 6 and protrudes outward is formed between the upwardly extending portion 4b and the inner bent portion 4c. Even if water is sprayed onto the handle part 6 due to wind and rain and tries to enter the interior of the outdoor unit 1, the convex part 4e will keep the water between the upwardly extending part 4b and the inner bent part 4c and the upper end 6b of the handle part 6. The gaps can be filled, water can be prevented from entering the interior of the outdoor unit 1, and electrical components installed inside the outdoor unit 1 can be prevented from getting wet and malfunctioning.

In addition, the upper end of the upper extending part 4b, the inner bending part 4c and the handle part 6 can be easily formed by forming a convex part 4e projecting outward between the upper extending part 4b and the inner bending part 4c. Since it is possible to block water in the gap with 6b, there is no increase in the manufacturing process due to filling the gap using a sealant or the like to block water, and there is no increase in cost due to the use of the sealant.

Further, since the protrusion 4e is formed along the upper end 6b of the handle portion 6 whose front and rear ends are inclined downward in the front and rear width direction, the entire area of the upper end 6b is in contact with the protrusion 4e. It is possible to reliably prevent water from entering the outdoor unit 1 from the handle part 6.

In addition, in this embodiment, the outdoor unit 1 of an air conditioner that enables indoor heating and cooling by blowing cold air and hot air from an indoor unit connected with refrigerant piping is described, but the invention is not limited to this. A hot water heating heat pump system that performs floor heating by connecting to refrigerant pipes leading to a floor heating panel embedded under the floor, a heat pump water heater system that stores high-temperature hot water in a hot water storage tank and uses it for hot water supply, baths, etc., geothermal heat and heat This invention is applicable to outdoor units 1 used in various systems such as geothermal heat pump devices to be replaced.
