Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a jet device for baths.

BACKGROUND OF THE INVENTION In recent years, jet jet devices have become popular even in general households.

An example of a conventional jet device will be described below based on the drawings.

In FIG. 4, 16 is a bathtub, 17 is a wall separating the bathroom from the outdoors, 18 is a suction pipe communicating with the bathtub 16, and 19 is a discharge pipe communicating with the bathtub 16. 20 has a suction port as suction pipe 1
8 is a pump casing (hereinafter referred to as pump casing) whose discharge port is connected to the discharge pipe 19, and 21 is an electric motor for driving the pump. 22 is an air suction pipe for generating bubbles.

The operation of the jet device configured as described above will be described below.

As the impeller 24 attached to the drive shaft 23 of the electric motor 21 rotates, water in the bathtub 16 flows through the suction pipe 18 communicating with the bathtub, and at the same time, air flows through the air suction pipe 2.
2, becomes a mixed water of steam and water in the pump casing 20, and is discharged into the bathtub 16 as a jet through the discharge pipe 19.

In the jet jet apparatus described above, the pressurizing pump equipped with the electric motor 21 is placed outdoors, but if there is space under the floor of the bathroom, it may be installed there. In this case, it can be installed close to the bathtub,
The suction and discharge pipes connecting the jet jet device and the bathtub can be shortened, and the pressurizing capacity of the device can be utilized to the fullest.

Problems to be Solved by the Invention Generally, electric motors are very sensitive to moisture, and if installed in a humid location, the frame or core may rust or the degree of insulation may deteriorate. By the way, even if the area under the bathroom floor is watertight with the inside of the bathroom, it is extremely humid when the bathroom is in use, so it is recommended to install a jet jet device under the bathroom floor. In such a case, the above-mentioned adverse effects would be exerted on the electric motor, which was very inconvenient.

The present invention was made in view of the above problems, and even when installed under the bathtub floor, it does not suffer from the adverse effects of moisture (
The object of the present invention is to provide a sheet jet device that is easy to use.

Means for Solving the Problems In order to achieve this object, the present invention accommodates a pressurizing pump including an electric motor in a closed container, and includes a communication port in the closed container to enable communication between the inside of the closed container and the outside of the bathroom. A trachea was established.

Effect of the present invention By using the above-described means, the humid air under the bathroom floor does not come into contact with the electric motor, and the air inside the sealed container can be replaced with outside air through the ventilation pipe that communicates with the outdoors. There is also little chance that the temperature will rise too high and cause damage.

Embodiments Hereinafter, embodiments of the jet device according to the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of a bathroom in which the shed jet device of this embodiment is installed. In Figure 1, 1 is a bathtub, 2 is a wall between the bathroom and the outdoors, 3 is a suction pipe communicating with the bathtub 1, and 4 is a wall between the bathroom and the outdoors.
5 is a discharge pipe communicating with the bathtub; 5 is a pump casing of a pressurizing pump whose suction port is connected to the suction pipe 3 and its discharge port is connected to the discharge pipe 4; and 6 is an electric motor for driving the pump. 7 is a drive shaft of the electric motor 6, and 8 is an impeller housed in the pump casing 5 and attached to the drive shaft 7. Reference numeral 9 denotes a case made of synthetic resin or the like, and a pressurizing pump including the electric motor 6 is housed within the case 9. case 9
The bathtub is sealed to prevent air from below the bathtub floor from entering the bathtub.

Reference numerals 10 and 11 are ventilation pipes provided between the case 9 and the wall 2, and the ventilation pipes 10 and 11 allow air to circulate between the inside of the case 9 and the outdoors. Further, the ventilation pipe 10 is connected to the bottom of the case 9, and the ventilation pipe 11 is connected to the top of the case 9.

In the jet device configured as described above, by turning on the electric motor 6, the pump casing 5
When the impeller 8 housed inside rotates, the water in the bathtub 1 flows through the suction pipe 3 communicating with the bathtub, and at the same time air flows in through the air suction pipe 12, causing the pump casing 5 to flow.
The water becomes a mixture of air and water inside the tank, and is discharged into the bathtub as a jet through the discharge pipe 4.

When the pump is operated, the temperature of the motor itself increases due to heat generated from the motor's windings, frictional heat from the bearings, and heat transmitted from the flowing hot water. Furthermore, the temperature of the air inside the case 9 also increases due to the dissipated heat, but the air that has become high temperature inside the case 9 can flow out from the ventilation pipe 11.
Since outside air can flow into the case 9 through the ventilation pipe 10, air circulation occurs between the inside of the case 9 and the outside, and a rise in temperature of the electric motor 6 can be suppressed.

A second embodiment of the present invention will be described below with reference to FIG.

The configuration of this embodiment differs from that of the first embodiment in that an electric fan 13 is provided inside the ventilation pipe 10.

In this embodiment, when the temperature inside the case 9 rises too much, by operating the fan 13 in the ventilation pipe 10, air is forcibly exchanged between the pump chamber and the outside air, and the pump is effectively stopped. This will reduce the temperature rise of the pump.

A third embodiment of the present invention will be described below with reference to FIG.

This embodiment differs from the first embodiment in that the ends of the ventilation pipes 10 and 11 extend into the case 9, and the respective ends 14 and 15 are connected to the inside of the housing of the electric motor 25. In this case, the drive shaft 26 of the electric motor 25
A cooling fan 27 provided in the main body actively circulates air.

This embodiment is effective when a relatively large electric motor is used, and the amount of heat radiated from the electric motor is so large that the temperature would reach a very high temperature in a short period of time if the motor was operated in a closed case.

Effects of the Invention The present invention houses a pressurizing pump including an electric motor in a sealed container, and the sealed container is provided with a ventilation pipe that allows communication between the inside of the sealed container and the outside of the bathroom. Even if installed, insulation failure and rust due to high humidity will not occur in the motor, and damage due to heating can be prevented.
