Description

The present invention relates to a waterbed that can be supplied with water stored inside.

Waterbeds use Pascal's principle to distribute body pressure evenly throughout the body, giving you an extremely comfortable sleeping experience that makes you feel as if you are floating on water. Also, by adjusting the temperature of the water stored inside the waterbed, you can avoid feeling cold when you go to bed in the winter or hot when you go to bed in the summer. . Furthermore, since there is no fiber filling used in futons and mattresses, the occurrence of dust mites can be suppressed, creating a sanitary environment.

Although it has such excellent characteristics, it is also true that it requires considerable effort and expense for maintenance and management. For example, in order to prevent the water stored inside the waterbed from spoiling, it is necessary to add a preservative, and if you forget to add a preservative and the water inside spoils, you will need to drain the water and reinject it. Also, if you use a heater to adjust the temperature of the water, you will incur electricity charges. Furthermore, if the heater breaks down, it is necessary to take it out from the waterbed and replace it, which requires a lot of effort. Furthermore, when trying to replace the water stored inside, it may contain preservatives, so even if you try to reuse it, it cannot be used for drinking purposes, and you will have to discard it.

When a large-scale earthquake occurs, facilities such as water pipes may be damaged and water cut off, and it may take time for restoration to occur. If you don't drink water even for a day, your life is at increased risk, and elderly people in particular are more likely to develop economy syndrome. As described above, securing water in times of disaster is extremely important, and various inventions related to water storage facilities as shown in Patent Documents 1 to 3 have been proposed.

In view of the current situation, it is conceivable to use the water stored in the waterbed as domestic water.

However, the water stored in the waterbed generally contains preservatives to prevent it from spoiling, and is not suitable for use as domestic water. Even if it were possible to secure water quality that could be used for domestic purposes, it would be extremely difficult to take the water out of the waterbed and use it.

The present invention has been made in view of these problems, and aims to provide a waterbed that can store water that can be used for daily life and that can be easily distributed.

The invention for solving the above problem is a water bed, which includes a water supply equipment that supplies water, a bed body that stores water supplied from the water supply equipment, and a water distribution equipment that distributes water stored in the bed body. It is characterized by comprising:

According to this configuration, the water bed includes a water supply facility that supplies water, a bed body that stores water supplied from the water supply facility, and a water distribution facility that distributes water stored in the bed body. When water is supplied from the equipment, the water stored in the bed body is pushed out and discharged from the water distribution equipment. This prevents the water stored in the bed body from remaining for a long period of time.

Preferably, the water supply equipment is characterized by having a water temperature adjustment mechanism that can adjust the water temperature to a predetermined temperature.

According to this configuration, the water supply equipment has a water temperature adjustment mechanism that can adjust the water temperature to a predetermined temperature, so by supplying water at an appropriate temperature to the bed body, there is no need to attach a heating device such as a heater to the bed body. , the bed itself can be kept at an appropriate temperature.

Preferably, the water temperature adjustment mechanism includes a solar water heater for raising the water temperature, and a water heater for receiving water supply from the solar water heater to adjust the water temperature and supplying the temperature-adjusted water to the bed body. It is characterized by having the following.

According to this configuration, the water temperature adjustment mechanism includes a solar water heater for raising the water temperature, receives water supply from the solar water heater to adjust the water temperature, and supplies water whose water temperature has been adjusted to the bed body. Since the water heater is equipped with a water heater, it is possible to save energy when heating the water.

Preferably, the bed body includes an upper layer that receives water directly from the water supply equipment, a lower layer located below the upper layer and connected to the water distribution equipment, and a passage section through which water stored in the upper layer and the lower layer can pass.

Since it is provided at the second end, which is the other end opposite to the end, the water stored in the bed body is sent to the water distribution equipment without being retained.

It is a block diagram of a water bed in this embodiment. It is a block diagram of water supply equipment. FIG. 3 is a front sectional view of the bed body.

Hereinafter, an embodiment of the waterbed 1 of the present invention will be described in detail with reference to FIGS. 1 to 3.

As shown in FIG. 1, the water bed 1 includes a water supply facility 10, a bed body 20, and a water distribution facility 30. Water adjusted to a predetermined temperature by the water supply equipment 10 is distributed to the kitchen 121, toilet 122, shower 123, etc. via the bed body 20 and water distribution equipment 30. This can prevent water from remaining in the bed body 20.

As shown in FIGS. 1 and 2, the water supply equipment 10 has a water temperature adjustment mechanism 11 that includes a solar water heater 12 and a water heater 15. The water temperature adjustment mechanism 11 is a so-called hybrid system in which tap water is supplied to both the solar water heater 12 and the water heater 15.

The solar water heater 12 is of a natural circulation type with an integrated tank 13, and is installed at a high position such as on the roof. On the other hand, the water heater 15 is installed on the ground. Water is delivered to the tank 13 from the water pipe 100a and stored therein. The temperature of the water stored in the tank 13 increases as it is irradiated with sunlight. Water W1 heated by the solar water heater 12 is sent to the water heater 15. The installation height of the solar water heater 12 is preferably 3 m to 8 m. When the installation height is high and the water pressure of water supplied to the water heater 15 exceeds a predetermined pressure range, it is preferable to provide a pressure reducing valve. Additionally, when the water is below a predetermined pressure range, it may be pressurized with a pressure pump for the purpose of stable water supply, but it is preferable to at least ensure water pressure that can supply water to the water heater 15 during a power outage. . Thereby, even during a power outage, the water stored in the tank 13 of the solar water heater 12 can be used for drinking or other purposes.

The solar water heater 12 is installed in a place facing south and exposed to sunlight, avoiding places where it will be shaded by buildings or trees. Further, it is preferable that the mounting angle is 25° to 35° from the horizontal plane. When the inclination angle of the roof deviates from 25° to 35°, it is preferable to provide a frame to adjust the installation angle. Thereby, the temperature of the water supplied from the water pipe 100a can be efficiently raised.

The water heater 15 is a device that adjusts the temperature of water W1 supplied from the solar water heater 12 and supplies water at an appropriate temperature to the bed body 20 and the bathtub 120, and connects the solar water heater 12 and the water pipe 100b. Water is supplied from both sides. When the temperature of water W1 supplied from the solar water heater 12 is high, it is mixed with water supplied from the water pipe 100b to reach the set temperature. Moreover, when the temperature of the water W1 supplied from the solar water heater 12 is low, it is heated to a predetermined temperature. The temperature is set remotely using the controller 110.

It is preferable that the temperature of the water stored in the bed body 20 is changed as appropriate depending on conditions such as outside temperature. For example, the temperature of the bed body 20 is generally recommended to be about 28° C. in winter and 24° C. in summer. These are just guidelines, and the temperature may be adjusted around 1°C to 1.2°C depending on the user's preference.

The optimum temperature of the water supplied to the bathtub 120 is about 40°C, which is generally higher than the optimum temperature of the water stored in the bed body 20. To solve this problem, the water heater 15 is provided with a three-way valve 16. The water W2 sent from the water heater 15 is supplied to the bathtub 120 or the bed body 20 via the three-way valve 16, so that water at an appropriate temperature can be supplied to the bathtub 120 and the bed body 20, respectively. . Moreover, it is preferable that the water heater 15 has a reheating function for increasing the water temperature of the bathtub 120.

As shown in FIG. 3, the bed main body 20 is held by a bed frame 40. The installation height of the bed body 20 is set so as to ensure a height at which water supplied from the solar water heater 12 is directly supplied by natural falling. Thereby, water stored in the solar water heater 12 can be supplied to the bed body 20 via the water heater 15 without relying on a pump or the like driven by electricity even during a power outage.

The bed frame 40 is provided with a recess 40a that opens upward, and the bed main body 20 is accommodated in the recess 40a. Thereby, the installation position of the bed body 20 is maintained.

The bed body 20 has an upper layer 21 and a lower layer 22. The upper layer 21 is a layer on which the user can lie down directly, and the lower layer 22 is a layer that is placed directly on the bed frame 40. The structure is such that water stored in the upper layer 21 and the lower layer 22 can pass through each other via a passage portion 23.

Water stored in the bed body 20 is supplied via a water supply port 24 attached to the upper layer 21. On the other hand, the water is supplied to the water distribution equipment 30 via the water distribution port 25 attached to the lower layer 22 . The water supply port 24 and the water distribution port 25 penetrate the bed frame 40 and are attached to the first end 20a of the bed body 20.

The passage portion 23 is provided at the second end portion 20b of the bed body 20. Thereby, water W3 supplied from the water supply port 24 flows into the first end 20a of the upper layer 21, flows into the lower layer 22 via the passage part 23 provided at the second end 20b, and further flows into the lower layer 22. Water is distributed to the water distribution equipment 30 from the water distribution port 25 attached to the first end 20a of the water distribution facility 30. Therefore, by supplying water adjusted to a predetermined temperature by the water heater 15 only to the upper layer 21, a sleeping environment with an appropriate temperature can be ensured. Moreover, since the water in all areas moves, the water stored in the bed body 20 does not stagnate in a specific area. Thereby, spoilage of water stored in the bed body 20 can be avoided. Note that the first end 20a and the second end 20b are respective ends of the bed body 20 in the longitudinal direction.

The water distribution equipment 30 is a piping equipment for distributing water stored in the bed body 20 to the kitchen 121, the toilet 122, the shower 123, and the like. Since the water W4 is supplied to the water distribution equipment 30 from the water distribution port 25 attached to the first end 20a of the lower layer 22, the temperature of the water W4 supplied to the water distribution equipment 30 is the same as that of the water stored in the lower layer 22. This is the temperature of the water. Thereby, for example, when water is distributed to the kitchen 121, it is possible to create a situation where cooking can be done with water at an appropriate temperature, compared to the case where tap water is used directly.

This embodiment is an example, and it goes without saying that modifications can be made without departing from the technical idea of the present invention.

The waterbed according to the present invention can also be used as a facility that can secure stockpiled water for use in times of disaster. Furthermore, by making the internal temperature similar to that of a bath, it can be used as a virtual bath where people who cannot easily take a bath can relax by lying down in the event of a disaster. The industrial applicability is great.
