[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain pipe for a motor which is attached to the bottom of a motor housing and drains dew condensation and the like generated inside the housing to the outside.

[0002]

2. Description of the Related Art The temperature of a place where a motor is installed varies depending on the purpose and use of the housing. For example, in a relatively low-temperature freezer or a fan motor of a freezing car, the temperature difference between the inside and outside of the housing causes the temperature of the housing to decrease. Since there is a possibility that dew condensation occurs inside the housing and accumulates on the inner bottom of the housing, and there is a possibility that each part will be flooded, it is necessary to install an appropriate drainage means.
In view of this, for example, as shown in FIG. 5, there is known a structure in which a drain pipe 101 having a substantially L-shaped cross section is attached to the bottom of a housing 100.

[0003]

By the way, in the case of such a drain pipe, it is possible to exhibit the effect of discharging the dew condensation water. However, if water enters from the lower part in the horizontal (horizontal) direction, it is relatively simple. In the meantime, the water may flow backward inside the drain pipe and enter the inside of the housing, which causes inconvenience. Therefore, this invention has been made in view of the circumstances described above, ingress of water fountain or the like toward the lateral and upward it is possible to effectively prevent the, yet due to breakage exchange, immediately
An object of the present invention is to provide a motor drain pipe that can be relatively easily inserted into and removed from a hole of a housing .

[0004]

Means for Solving the Problems] That is, this invention provides a motor for a drain pipe for draining condensation water or the like generated in said inner housing attached to the bottom of the housing of the motor to the outside of said drain pipe Lower half of body
The portion is formed in a substantially L-shape having a bent portion bent obliquely.
Is, the lower end surface of the drain pipe is formed to be substantially along the horizontal direction, a two-divided head thick shape of the drain pipe on an inner peripheral surface and outer peripheral surface upper end surface of the head portion directed Subomari tapered, the flange to the intermediate portion of the body
Formed of elastic material and inserted into the mounting hole of the housing body
It is easily configured .

[0005]

In the present invention, the drain pipe is bent in a substantially L-shape, and the lower end face of the drain pipe is formed so as to extend substantially in the horizontal direction. Water or the like to enter is blocked by the inner wall surface bent in a substantially L-shape, and it is possible to prevent water from infiltrating into the upper rear portion and the inside of the housing.

In addition, in this invention, the drain pipe 2
The divided head is thick and the inner and outer peripheral surfaces of the head are tapered toward the upper end surface, so that the head can be easily pulled out of a hole formed in the housing. Ma
In addition, the housing is made
It can be easily inserted into the hole of the ring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view showing a drain pipe for a motor according to the present invention. The motor drain pipe is made of a material such as elastic rubber, and is formed in a tapered shape in which the inner and outer peripheral surfaces 11A and 11B of the head 11 of the main body 1 are tapered toward the upper end surface.

The drain pipe for a motor has a bent portion 2 in which a lower half of a main body 1 is bent obliquely and is formed in a substantially L-shape. It is formed in a thicker shape than in the prior art, so that the durability is greatly improved. Unlike the conventional one, even if it is attached to the housing 3 without using an adhesive, the necessary strength can be sufficiently secured. Has become. The head 11 has slits 11C having a fixed width at two positions facing each other.

Further, the motor drain pipe is formed such that the lower end surface 2A of the bent portion 2 extends substantially in the horizontal direction, and attempts to enter the lower end surface 2A of the drain pipe from the lateral direction or from below. Water and the like are blocked by the inner wall surface of the bent portion 2 bent in a substantially L-shape, so that water can be prevented from entering the upper back portion and the inside of the housing. A flange 12 is formed at an intermediate portion of the main body 1 so as to prevent the main body 1 from coming off when the main body 1 is inserted into the housing 3.

Therefore, according to this embodiment, for example, FIG.
When it is attempted to remove the drain pipe body 1 from the state where it is attached to the housing 3 as shown in FIG.
The slit 11C of the head 11 is closed and the head 11 contracts as if it were closed. Then, when the head 11 is further pulled in the same direction from the state shown in FIG.
Is largely bent and can pass through the hole 3A relatively easily.

[0011]

As described above, according to the present invention, the drain pipe is bent in a substantially L-shape and the lower end surface of the drain pipe is formed so as to extend substantially in the horizontal direction. The water and the like entering from the lateral direction or the lower side toward the lower end surface of the housing are prevented by the inner wall surface bent in a substantially L-shape, so that water can be prevented from infiltrating into the upper back portion and the inside of the housing. This has the effect of greatly improving the degree.

In addition, in the present invention, the drain pipe 2
The divided head is thick and the inner and outer peripheral surfaces of its upper end are tapered toward the upper end, so that it can be easily removed from the hole formed in the housing. Or easy because the flange is made of elastic material
Can be inserted into In addition, since the strength of the head is increased, stable fixing can be realized without the need for an adhesive, so that troublesome work such as peeling off the adhesive is not required, and it is also possible to easily replace just by pulling out.
