Description

TECHNICAL FIELD The present invention relates to a simple shower device mainly used in a general household.

[Conventional technology]

Conventionally, a shower device used in a general household uses hot water boiled by a gas water heater or an electric water heater that uses midnight power to guide it to the shower device. There was one shown in FIG.

FIG. 5 shows a conventional device of this type.
30 is a heater for heating water into hot water by using gas or electricity, 31 is a mixing stopper for mixing the hot water with water to adjust the temperature of the hot water, and 32 is for controlling the amount of hot water discharged. The control valve 33 is a pipe for sending water or hot water.

The conventional device is configured as described above. For example, water supplied from a water pipe is sent to a heater 30 through a pipe 33, and a gas combustor attached to the heater 30 or an electric heater (both not shown) is used. ) And heated to hot water.

Since the heater 30 needs to supply hot water according to the purpose of use to various places such as kitchens and bathtubs that use hot water other than a shower, the temperature of the hot water is generally slightly lower than the boiling temperature.
It is heated to around 5 ° C.

Therefore, the hot water heated to about 85 ° C. by the heater 30 is sent to the mixing tap 31, mixed with the water by the mixing tap 31 to be an appropriate temperature hot water, and then sent to the control valve 32, and the control valve 32 releases the amount of hot water. Was used as a shower while controlling.

[Problems to be Solved by the Invention]

In the conventional device as described above, the heater 30 cannot be moved, and the shower can be used only in a limited place such as a bathroom or a shower room.

Further, in the conventional configuration, there is a problem that the distance of the pipe 33 from the heater 30 to the hot water outlet is long, and heat is dissipated in the cold pipe 33 at the beginning of use, and further piping equipment is required. However, there was a problem that it became expensive.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain a simple shower device that does not require expensive piping equipment and is inexpensive and can be moved to any place for use.

[Means for Solving the Problems]

A simple shower device according to the present invention includes a tank provided inside a movable body, a heater attached to the tank, a pump for extracting hot water in the tank to the outside, and a shower head for discharging hot water taken out by the pump. And a solenoid valve attached between the shower head and the pump, the stepped portion is formed on one side of the bottom of the tank, and the space formed under the stepped portion The pump is arranged in the above, and a communication passage that connects the uppermost part of the pump chamber of the pump and the lower part inside the tank is provided in the step portion.

[Action]

In the simple shower device according to the present invention, the water in the tank is heated by the heater and is boiled into hot water having a suitable temperature.
The boiling water is introduced into the hose from the lower part of the tank by opening the solenoid valve and operating the pump, and is discharged as a shower from the shower head at the tip of the hose.

After use, when the pump is stopped and the solenoid valve is closed, some air is trapped in the uppermost part of the pump chamber, but this trapped air is returned to the tank through the communication passage during the next pump operation, The idle rotation due to the air-deflection phenomenon is prevented.

〔Example〕

 An embodiment of the present invention will be described below.

FIG. 1 is a perspective view showing the configuration of a simple shower device according to the present invention, FIG. 2 is a side sectional view showing a state in which a shower head and a hose are housed, and FIG. 3 is an enlarged sectional view of an essential part. In FIG. 3, 1 is a main body, 2 is a tank for storing water provided in the main body, 3 is a heater for heating the stored water, 4 is an electric pump, and 5 is an upper front surface of the main body 1. 6 is a shower head, 7 is a hose, and 8 is a temperature sensor for detecting the temperature of hot water. For example, a thermistor is used.

Reference numeral 9 is a solenoid valve which is located between the shower head 6 and the pump 4 and attached to a part of the hose 7, and 10 is a control device which controls the energization of the heater 3, the pump 4, and the solenoid valve 9.

As shown in FIG. 2, the tank 2 has a step portion 2a formed on one side of the bottom portion, and a pump 4 is arranged in a space formed below the step portion. As shown in FIG. 3, the pump 4 has a rotary vane 4b that is rotationally driven by a motor (not shown) in a pump chamber 4a, and one end of its suction pipe 11 is connected to the lower portion of the tank 2 to discharge One end of the pipe 12 is connected to the hose 7 via a solenoid valve 9.

Reference numeral 13 is a communication pipe for communicating the uppermost part of the pump chamber 4a with the inside of the tank 2, and has a small diameter communication port 1 provided on the pump side.
4 and the large diameter communication port 15 provided on the tank 2 side form a communication passage.

Reference numeral 16 denotes a storage chamber provided in the lower front portion of the main body 1, in which the hose 7 and the shower head 6 can be stored when not in use.

The simple shower device shown in the above-described embodiment has each device for storing and heating water stored in the main body 1, that is, as shown in FIG. 2, water is stored in the tank 2 and heated by the heater 3. It becomes hot water, which is pressurized by the pump 4 and discharged from the shower head 6 via the hose 7.

Further, the control device 10 controls the hot water temperature and the water amount,
By operating the operation unit 5, the temperature detection signal from the temperature sensor 8 is transmitted to the control device 10, and the control device 1
0 controls energization of the heater 3 by this signal.

Water is supplied to the tank 2 by the opening / closing lid 1 provided on the upper portion of the main body 1.
Open a. At the time of supplying this water, since the solenoid valve 9 is closed, air is trapped in the pump chamber 4a of the pump 4 located between the tank 2 and the solenoid valve 9, and the pump 4 remains in this state. When driven, the rotor blade 4b
Although a so-called air-deflection phenomenon occurs in which the water does not spin out and pushes out water, the uppermost part of the pump chamber 4a and the inside of the tank 2 are connected by the communication pipe 13 in the configuration of the present embodiment, and the pump 4 is operated. At times, the air trapped in the pump chamber 4a can be released into the tank 2 through the communication pipe 13.

Therefore, the air is never trapped in the pump chamber 4a, and the idling of the pump 4 can be prevented.

Here, in the above embodiment, since the step portion is formed on one side of the bottom portion of the tank and the pump is arranged in the space formed under the step portion, the space for installing the pump is provided inside the main body. It can be secured in a small space, and the main body can be downsized.

In addition, the stepped portion is provided with a communication passage that connects the uppermost part of the pump chamber and the lower part of the tank, so that the air trapped in the pump chamber can be returned to the tank in the shortest distance, and the occurrence of the air jam phenomenon occurs. Can be prevented quickly and surely, and the structure of the communication passage can be made simple and inexpensive. Furthermore, the communication port 1 on the pump side that constitutes the communication passage
Since 4 has a small diameter and the communication port 15 on the tank side has a large diameter, a baffle effect is obtained in the flow of hot water, and hot water leaking from the pump chamber 4a through the communication pipe 13 into the tank 2 becomes a jet flow. Therefore, it is possible to prevent the discharge into the tank 2.

Further, FIG. 4 is a sectional view of an essential part showing another embodiment of the present invention.
When the shower is used, the communication port 15 is opened horizontally and the communication port 15 is opened in the horizontal direction. The effect of being able to stir the hot water of the shower head 6 and to make the temperature of the hot water discharged from the shower head 6 uniform and to prevent upward splashing when the amount of hot water in the tank 2 becomes small is obtained. To be
