Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a simple shower device for use in general households.

[Conventional technology]

Conventionally, shower devices used in general households have been used by directing hot water heated by a gas water heater or electric water heater to the shower device. It was structured like this.

That is, in FIG. 3, 30 is a heater for heating water to hot water using gas or electricity, 31 is a mixing faucet for mixing hot water and water to adjust the temperature of the hot water, and 32 is a discharger. A 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 the heater 30 through the pipe 33, and heated by the heater 30 to become hot water.

Since the hot water heated by the heater 30 is used for purposes other than showering, the temperature of the hot water is heated to a high temperature close to the boiling temperature.

Therefore, hot water is mixed with water using a mixing faucet 31 to obtain hot water at an appropriate temperature, and then sent to a control valve 32, and used as a shower while adjusting the amount of hot water released.

[Problem to be solved by the invention]

With conventional devices like the one mentioned above, the heating temperature is high, so in order to lower the temperature of hot water to the appropriate temperature for showering, it is necessary to mix it with water. There were restrictions on where it could be used, rather than being able to move it to other places to use it.

In addition, since the piping 33 from the heater 30 to the shower device is long, cold water may be emitted for a while at the start of use, and heat may be absorbed within the piping 33, making it extremely difficult to adjust the temperature of the hot water. There were also some problems.

This invention was made in order to solve the above-mentioned problems, and provides a simple shower device that can be moved and used anywhere and that can always control the temperature of hot water at a constant and appropriate temperature. The purpose is to

[Means to solve the problem]

The simple shower device according to the present invention incorporates a water storage tank, a heater, and a pump in a movable main body, and uses pressurized water supply by the pump to send hot water in the water storage tank to a shower head and discharge hot water. A temperature sensor for detecting the temperature of hot water boiled in a water storage tank is attached to a step formed at the bottom of the water storage tank, and a heater is disposed below this step.

[Effect]

In this invention, the water in the water storage tank is heated by energizing the heater, and when the water is heated to a predetermined temperature, the temperature sensor detects this temperature and the control device stops energizing the heater.

The temperature sensor is installed on the step at the bottom of the water storage tank, and is located in the middle of the convection flow caused by the heating of the heater installed below this step, so it does not receive radiant heat from the heater. Accurately detect the temperature of hot water.

〔Example〕

An embodiment of the present invention will be described below.

FIG. 1 is a perspective view of a simple shower device showing an embodiment of the present invention, and FIG. 2 is a side sectional view thereof.
The hose and shower head are shown stored in the storage area inside the main unit.

In the figure, 1 is the main body, 2 is a water storage tank, 3 is a heater, 4 is a pump, 5 is an operation panel, 6 is a shower head, 7 is a hose, 8 is a temperature sensor, 9 is a control device, 10 is the bottom of the water storage tank 2 This is a stepped portion formed on one side, and a sensor mounting portion 11 of the temperature sensor 8 is integrally provided therein.

12 is a solenoid valve; 13 is a suction pipe connected to the suction port of the pump 4; 14 is a discharge pipe also connected to the discharge port of the pump 4; 15 is a lid covering the top opening of the water storage tank 2; 16 is the storage section.

As shown in the figure, the simple shower device of the above embodiment houses all the devices for storing and heating water inside the main body 1, and water is stored in a water storage tank 2 and heated by a heater 3 to become hot water. When the pump 4 operates, it is sucked in through the suction pipe 13 and discharged into the discharge pipe 14.
The hot water is discharged under higher pressure and is discharged from the shower head 6 via the solenoid valve 12 and the hose 7.

Further, the control device 9 controls the temperature and amount of water, and is controlled by operating the operation panel 5. The detection signal from the temperature sensor 8 is transmitted to the control device 9, which controls the supply of electricity to the heater 3 to maintain the water temperature at a constant temperature that is comfortable for a shower.

Here, in this embodiment, as shown in FIG.
At the same time, the heater 3 is installed in the water storage tank 2 with the heater 3 located below the stepped part 10, and the convection of water caused by heating by the heater 3 is as indicated by the arrow in the figure. flowing like
Since the temperature sensor 8 is located in the middle of this flow, it is not directly exposed to radiant heat from the heater 3 and can accurately detect the temperature of the hot water.

Therefore, with the above configuration, the temperature of the hot water in the water storage tank 4 can be accurately detected, and since the main body 1 is movable, there is no restriction on the place of use, and the water storage tank 2 and the shower head can be moved. The distance between 6 can be made much shorter than before, which eliminates the problem of heat being lost or cold water being sprayed for a while after use, and makes it easier to adjust the water temperature. be.

〔Effect of the invention〕

As described above, according to the present invention, a water storage tank, a heater, and a pump are incorporated into a movable main body,
Since the system uses a pump to send hot water to the shower head and discharge it, it can be easily moved and used anywhere, and since no piping equipment is required, it can be provided at a low cost.It also detects the temperature of the hot water in the water storage tank. Since the temperature sensor is installed so as not to receive radiant heat from the heater, it has the effect of accurately detecting the water temperature.
