Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a portable washer.

[0002]

2. Description of the Related Art Conventionally, as a device for assisting excretion,
A sanitary washing device has been proposed. This sanitary washing device
It discharges hot water to the local area of the human body, and has been remarkably popular due to the recent increase in hygiene thinking. With this spread, a sanitary washing device of a type that can be carried and used even when going out has come to be proposed. It is a so-called portable washer.

There are also two methods for securing hot water in this portable washing machine, one is to use hot water obtained from the outside by putting it in a tank, and the other is to put it in the tank. The heated water is heated by a heater such as a nichrome wire.

[0004]

However, the first method requires an external hot water supply means near the place where it is actually used, and the second method requires at least 1 unit.
A power source of about 00 Watts is required, and batteries or the like cannot be used.

As described above, the conventionally provided portable washer can sufficiently exert its effect in a limited place, but cannot exert its effect in other places.

An object of the present invention is to propose a portable washing device which can obtain hot water anywhere regardless of the place of use.

[0007]

The portable cleaning device of the first invention made to solve the above problems is a portable cleaning device that is portable and discharges cleaning water to a local area of a human body. There is provided a tank for storing the cleaning water, and a Peltier element for heating the cleaning water stored in the tank.

According to the portable cleaning device of the present invention, the cleaning water stored in the tank is heated by the Peltier element, so that the local area can be cleaned at a comfortable temperature.

Further, since this Peltier element can be used with a low electric power such as that of a portable battery, hot water can be obtained anywhere regardless of the place of use.

Moreover, since the temperature response is good, the waiting time before the start of use is short.

Further, when the battery is integrally provided, it is not necessary to carry a separate battery as a driving source of the Peltier device, which is convenient. The battery can be used not only as a drive source for the Peltier element but also as a drive source for a pump for controlling the discharge of washing water, an electromagnetic on-off valve, a motor for expanding and contracting the nozzle, and the like.

When the battery is provided near the heat absorption side of the Peltier element, the heat absorption side is warmed by heat radiation from the battery, and the Peltier element can always be used in a good characteristic region.

Further, when the temperature detecting means for detecting the temperature of the cleaning water is provided, the temperature of the cleaning water can be managed and the temperature can be controlled.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described below in order to clarify the structure of the present invention described above.

FIG. 1 shows a schematic view of the portable cleaner 10 of the present invention. This portable cleaner 10 includes a slide tank (cleaning water retention part) 11, a nozzle housing body 12, and a nozzle 1.
3, a pump (not shown), a power supply for driving the pump, and a switch.

The sliding tank 11 of the portable cleaner 10 has a heating means 14 (see FIG. 2 and subsequent figures).

2 and 3 show cross sections of the portable cleaner 10 of FIG. As shown in FIGS. 2 and 3, the heating means 14
Is fixed to the inner wall of the slide tank 11, and the nozzle housing main body 12 is configured so as to match the shape of the inner wall of the slide tank 11 to which the heating means 14 is fixed. By doing so, the nozzle housing body 12 can be smoothly slid and taken out from the slide tank 11.

Further, the heating means 14 can be easily fixed to the slide type tank 11 when it is placed in a mold from which the resin compound forming the slide type tank 11 is injected and is solidified together with the injected resin compound. it can.

4 to 7 show a state in which a Peltier element 14b is used as the heating means 14. What is a Peltier element?
It utilizes the phenomenon that heat is generated or absorbed when a current flows through the joint surface of different metals.

In FIG. 4, a Peltier element 14b and a heating plate 15 made of copper, aluminum or the like having high thermal conductivity are inserted in a part of the slide tank 11. In FIG. 5, the Peltier element 14 b is inserted into a part of the slide tank 11 and the inner wall surface is covered with the heating plate 15. Further, in FIG. 6, the slide type tank 11 is configured by a Peltier element 14b, and the inner wall surface thereof is covered with the heating plate 15.
This is obtained by fixing the Peltier element 14b and the heat plate 15 with screws, an adhesive or the like. Further, it is conceivable to form a shape as shown in FIG. 7 by injection molding or the like, and fit the Peltier element 14b fixed to the hot plate with a screw, an adhesive or the like. In this case, either the hot plate 15 or the Peltier element 14b may be fitted. Also, a sealing means such as an o-ring may be used together when fitting.

Here, the Peltier element 14b is used as the heating means 14 because the temperature response is good at the voltage of the dry cell level, and if it is about 200 ml of water, it takes 35 to 4 in a short time.
This is because hot water of 0 ° C. can be obtained (details will be described in the section of Examples).

Further, since a large-scale control means is not required, the portable washing machine can be further downsized, and when a short circuit occurs, a large current does not flow and it is safe. .

FIG. 8 illustrates an electric circuit for heating the cleaning water stored in the slide type tank 11 by using the Peltier element 14b. First, a battery 18 as a power source is built in the nozzle housing body 12. Further, a set of contact switches 16 extending from the positive electrode and the negative electrode of the battery 18 are fixed to the rear end of the nozzle housing body 12. On the other hand, from the Peltier element 14b fixed to the slide type tank 11, another set of contact switches 1
6 is fixed to the tip of the slide tank 11. The electric circuit configured as described above is brought into conduction by connecting the two sets of contact switches 16 with each other in a state where the nozzle housing body 12 is pulled out. In addition, the nozzle housing body 12 is in a non-conducting state when it is stored.

Here, a dry cell may be used as the battery 18. Further, as shown in FIG. 9, when the battery 18 is formed in parallel with the pump, a common battery is used by both, so that the circuit is simpler and more compact, which is more preferable.

Alternatively, as shown in FIG. 10, a variable load may be provided in the circuit, the variable load 19 may be connected to the control device, and the heating temperature may be changed according to the outside air temperature measured by the temperature detecting means. This is preferable because the degree of temperature rise of the wash water can be changed according to the outside air temperature.

The present invention is not limited to the above-described embodiment, but can be carried out in various forms without departing from the scope of the invention, for example, the following modifications are possible.

(1) Convection means may be provided in the slide tank 11. This is preferable because the water temperature in the slide tank becomes uniform quickly. In this case, a screw motor, a fan or the like can be used as the convection means.
The convection means may be provided at the upper end of the slide tank so as not to disturb the storage.

(2) A temperature detecting means may be provided and the heating means 14 may be turned on at a predetermined temperature or lower. In this case, it is possible to perform temperature control such that the heating means 14 operates on a cold day when hot water is needed and the heating means 14 does not operate on a hot day when hot water is unnecessary, which is preferable.

(3) Peltier element 14 shown in FIGS.
A plurality of b may be provided.
