Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a two-tank heating tank in which the interior of the container is partitioned by a movable membrane.

[Conventional technology]

In a domestic bath, the water in the bath is usually not changed, so the water in the bath becomes dirty as it is used. Therefore, when getting out of the bath, it is customary to prepare separate clean water and wash your body with this hot water.

And as a means of producing this clean hot water,
This was done by passing tap water into a bath kettle and boiling the tap water in the bath kettle.

In some cases, tap water has also been heated by inserting a heat exchanger into the bathtub and passing the tap water through the heat exchanger.

[Problem that the invention attempts to solve]

However, the method of making hot water by passing tap water into the bath pot and connecting a water hose to the water outlet of the bath pot can cause the bath pot to run dry if the tap water is turned off by mistake, or the bath pot may run dry or leak from the gasket. There were problems in that the bathtub could be damaged due to water leakage or water pressure becoming too high. Also, depending on the type of bath kettle, if you increase the amount of tap water a little,
The temperature dropped and some things became useless.

In addition, the method of heating tap water by inserting a heat exchanger into hot water has the problem that it can only produce water that is slightly warmer than tap water.

Of course, if you first fill this heat exchanger with water and then soak it in a hot water tank, the water will come out at approximately the same temperature as the hot water tank, but in order to increase the heat transfer area, the device Since the volume of water was small relative to the total volume, the amount was insufficient.

The present invention was developed in view of the above circumstances, and an object of the present invention is to provide a two-tank heating tank capable of ensuring a predetermined amount of hot water without leaving the bathtub empty.

[Means to solve problems]

The two-tank heating tank according to the present invention that achieves this purpose is a two-tank heating tank that is used in a bathtub, and a movable membrane is provided approximately in the center of the sealed container to keep the two tanks inside the container. Each of the partitioned tanks is provided with an inlet and an outlet.

Here, the movable membrane itself may be formed in approximately the same shape as the outer container, and may be a bendable non-elastic synthetic resin membrane, but it may be made of an elastic body (for example, a rubber plate) and The membrane may expand or contract depending on the amount of

The material of the sealed container may be made of metal plate, synthetic resin plate, sheet or rubber plate, and the outer plate of the container may be flat or wavy. The present invention is applicable to both cases where fins are formed on the outer panel of the container and cases where fins are formed on the outer panel of the container.

[Effect]

Next, a method of using the two-tank heating tank according to the present invention and its function will be explained.

First, fill one tank with water, which is separated by a movable membrane, and soak it in the hot water tank. As a result, the heat from the hot water is transferred, heating the water inside and increasing its temperature.

Next, when using the hot water contained in these two-tank heating tanks, pour it into the other tank separated by a movable membrane using a hose connected from the inlet and outlet to the water faucet. water, move the movable membrane,
Make sure to expel hot water.

In this case, hot water comes out from the inlet and outlet of one of the tanks, and by connecting a hose with a shower to this inlet and outlet, the user can take a shower of hot water.

When all the hot water has been poured out, the other tank will now contain water, and by soaking it in the bath, it will be heated and become hot water. In this case, it takes time for the water in the container to warm up, but the amount of shower that is usually used after taking a bath is not large, and furthermore, when one person gets out of the bath,
Since it takes a considerable amount of time for the next person to take a bath, the water that enters the container during this time is heated and becomes hot water.

〔Example〕

Next, with reference to the attached drawings, an embodiment of the present invention in which the present invention is specifically heated will be described to provide an understanding of the present invention.

Here, FIG. 1 is a side sectional view of a two-tank heating tank according to an embodiment of the present invention, FIG. 2 is a plan view of a two-bath heating tank according to the above embodiment, and FIG. 3 is a diagram showing the above embodiment. It is a side view of the switching valve used for the two-tank heating tank concerning.

As shown in FIGS. 1 and 2, a two-tank heating tank 10 according to an embodiment of the present invention includes a container 11 constituting an outer case, and two tanks ( That is, it is configured to include a synthetic resin membrane 14 which is an example of a movable membrane that partitions into a tank 12 and a tank 13). These will be explained in detail below.

The container 11 is made of a metal plate or a synthetic resin plate, and the outside thereof is formed into a wave shape to increase the heat transfer area. Note that if the container 11 is made of a metal plate, its strength will be increased and its heat conduction will be improved.

Approximately in the center of the container 11, an outer container 11 is provided.
A synthetic resin membrane 14 formed in approximately the same shape as the container 11 is attached to seal the periphery of the container 11 in the tank 1.
It is designed to be divided into a tank 2 and a tank 13. In addition,
This synthetic resin membrane is preferably made of a material with poor thermal conductivity, thereby making it possible to prevent heat from being transferred from adjacent tanks and to prevent hot water from cooling during use.

At the top of the tanks 11 and 12, there is an inlet/outlet 1.
5 and 16 are formed respectively, and these inlet and outlet ports 15 and 16
Attached are caps 19 and 20 to which hoses 17 and 18 are connected, respectively.

One of the hoses 17 and 18 is connected to a water faucet (not shown), and the other is connected to a well-known water shower (not shown).

At the top of the container 11, a handle 21,
22 is attached so that the two-tank heating tank 10 can be lifted up.

When using this two-tank heating tank 10, first connect the hose 17 to a water faucet and fill the tank 12 with tap water. Then, this two-bath heating tank 10 is placed in a hot water bath and heated.

When in use, the hose 18 is connected to a water faucet, and the hose 17 is connected to a water shower.
By filling the tank 13 with water in this way, the hot water in the tank 12 can be expelled and water can be discharged from the water shower.

Next, tap water is poured into the tank 12, so it is immersed in the bath again to warm it up. By repeating the above operations, the water heated by the hot water tank can be used repeatedly.

FIG. 3 shows a switching valve 23 used in this two-tank heating tank, and the spouts 24 and 25 of this switching valve 23 are connected to the pouring and draining ports 15 and 16.

In the switching valve 23, the flow direction of water is switched by turning a knob 26.
When the knob 26 is set to the position B in the figure, all water passages are closed, but by setting the knob 26 to the position A in the figure, the connection port 29 of the hose 27 is closed. The spout 24 is connected to the spout 24, and the connection port 30 of the hose 28 and the spout 25 are connected. In this state, by connecting the hose 27 to the water faucet and the hose 28 to the water shower, the water from the water faucet will enter the tank 12, and the warm water in the tank 13 will be sprayed. I'm going to get out of the shower.

Next, by adjusting the knob 26 to position C, the connection port 30 of the hose 28 and the spout 24 are connected, and the connection port 29 of the hose 27 and the spout 25 are connected.
Water from the faucet enters the tank 13 from the spout 25 through the hose 27, and at the same time, the hot water in the tank 12 flows into the spout 2.
4. The water will come out of the shower through the hose 28.

In addition, if the water pressure of the water supply is too high, attach a pressure reducing valve to the water faucet or the above switching valve.
It is preferable to lower the pressure of the water supply to a predetermined pressure before use. Furthermore, if the water pressure is too high, install a safety valve on the switching valve with an outlet connected to the other connection port, and if the pressure exceeds a certain level, the safety valve will open and tap water will be discharged from the water shower. It is also possible to make it appear directly.

Further, the two-tank heating tank according to the above embodiment can be heated by solar heat, and the container itself can be made of foldable vinyl or the like to make it convenient to carry.

In addition, the container is formed into a cylindrical shape, a moving piston is provided in the cylindrical body, and an inlet and an outlet are provided in each of the rooms partitioned by the piston, and this piston is used instead of the movable membrane. It can also be used to move warm water inside.

Further, in the above embodiment, the movable membrane was provided approximately at the center of the container, but it may also be provided diagonally across the container, thereby making it possible to reduce the amount of movement of the movable membrane.

[Effect of idea]

As is clear from the above description, the two-bath heating tank according to the present invention does not need to be connected to a bath pot, so there is no possibility of the bath being heated empty or the bath pot being damaged by water pressure.

In addition, if you take the time, you can provide shower water with a temperature that is close to that of the bath water.
Since hot water can be supplied at the same time as the water is replaced, the hassle of refilling the water can be saved.

Furthermore, since there is no internal space like a heat exchanger, even if the volume is small, it is possible to produce enough hot water for one bath.
