Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a bathroom heating device, and more particularly to a technique for effectively heating a bathroom with a simple configuration using a hotbed mat. [[Background Art] Conventionally, bathroom heating, especially floor heating, is carried out by using a hot bed mat and introducing hot water into a hot water passage formed in the hot bed mat. This is done through a separate system from the hot bed mat, and the hot water supply route to the hot bed mat must be constructed separately, which is costly, and the temperature control of the hot bed mat is not the same as the temperature control of the hot water in the bathtub. This has to be done separately, and the management of raising the temperature to an appropriate level is troublesome, and the configuration for that purpose is also complicated.

In order to solve such problems,
As in Publication No. 28338 and Publication No. 48330 of 1983, a configuration has been proposed in which the hot water supplied to the bathtub is used to heat the floor and walls. It is a method that uses only the heat of the pine tree, and is not designed to use the hot water effectively.In particular, in hotbed pine trees, hot water that has warmed the pine tree is spouted from below to create a shower from below. It cannot be used as such.

[Object of the Invention] The present invention has been made in view of these problems, and its purpose is to supply hot water exclusively for the hot bed mat by incorporating the hot bed mat into the path for supplying hot water to the bathtub. It is possible to eliminate the work of turning the path and reduce the cost, while effectively heating the hotbed pine and heating the bathroom with the hot water supplied to the bathtub. The purpose of the present invention is to provide a bathroom heating device that can be used by emitting heat to the bathroom.

[Disclosure of the Invention] The bathroom heating device of the present invention includes a hot water passage path 4 for the hot bed mat 3 in the middle of the path for supplying hot water to the bathtub 1, and a large number of hot water injection holes 2 at the end of the hot water passage path. By configuring it in this manner, the above object is achieved. In other words, by incorporating the hot bed pine 3 in the middle of the path for supplying hot water to the bathtub 1, it is possible to omit the construction of a dedicated hot water supply path to the hot bed pine 3, thereby significantly reducing costs. When hot water is supplied to hot bed mat 3, hot water can always be supplied to hot bed mat 3, so that not only hot bed mat 3 but also the bathroom can be heated in a timely manner, so that suitable heating can be performed when taking a bath. In addition, since heating of the hot bed mat 3 is performed by hot water to the bathtub 1, it is possible to save energy, and a large number of hot water injection holes 2 are provided at the end of the hot water passage path 4 in the hot bed mat 3. Therefore, the temperature of the hot bed mat 3 can be raised by the hot water supplied to the hot water passage path 4, and the hot water can be directly heated like a shower from below, and the hot water injection hole is located at the end of the path. Therefore, the hot water injected from the hot water injection hole 2 is at a low temperature after being heat exchanged in the hot water passage path 4, and there is no risk of burns.

Embodiments of the present invention will be described in detail below based on the drawings.

The route for supplying hot water to the bathtub 1 is as shown in Figure 1.
Water governor switch built into heat source device 5
WG, water flow switch FSW, waterway switching motor valve MV, check valve AV, safety solenoid valve GV ₁ on the fuel gas supply side, main solenoid valve GV ₂ , gas proportional valve GCV, heat exchanger 8, fan F, etc. It is connected to the bathtub 1 via the bathtub 1, so that hot water at an appropriate temperature can be supplied to the bathtub 1. In such hot water supply, that is, when filling the hot water, it is preferable to automatically stop the hot water supply when the water level reaches a certain level, or to maintain the water level at a substantially constant level depending on the use of the hot water. As described above, a well-known structure can be employed for supplying hot water at an appropriate temperature to a constant water level in the bathtub 1 and for maintaining the water level at a substantially constant water level depending on the use of the hot water.

A hot water passage path 4 for the hot bed pine 3 is constructed in the middle of the path for supplying hot water to the bathtub 1.In this way, by incorporating the hot bed pine 3 in the middle of the path for supplying hot water to the bathtub 1, the hot bed pine By omitting the construction of a dedicated hot water supply route to mat 3, we aim to significantly reduce costs, and when supplying hot water to bathtub 1, we always supply hot water to hot bed mat 3, heating not only hot bed mat 3 but also the bathroom in a timely manner. However, suitable heating is provided during bathing.

The mat switching unit MC allows switching between two states: a heating-only state shown in FIG. 2a and a bath-only state shown in FIG. 2b. By the way, the matsutto switching trick
A temperature sensor (not shown) is built into the MC, and when high-temperature water of, for example, 93°C is supplied during reheating, the MC switches to switch the mat based on the temperature detected by the temperature sensor. Figure 2b
Switches to bath-only state as shown, Hotbed Matsuto 3
Hot water with a temperature higher than a certain temperature (approximately 39 to 42 degrees Celsius) is not supplied to On the supply side,
It is equipped with a hot water supply stop valve 6 that closes at about 45°C and opens at about 40°C, and in addition to providing heating with the hot water supplied to the hot water passageway 4, the hot water passageway By forming the hot water injection hole 2 at the end of the hot water injection hole 2, the hot water injected from the hot water injection hole 2 can be directly heated like a shower from below. 4, the hot water injected from the hot water injection hole 2 is at a low temperature after heat exchange in the hot water passage path 4, and hot water is supplied to the upstream side of the hot water injection hole 2. By providing the stop valve 6,
It is possible to prevent the injection of high temperature water from the hot water injection hole 2, resulting in high safety, and by forming the hot water injection hole 2 at the end of the hot water passage path 4, the end of the hot water passage path 4 is opened, and the hot water can be heated. It is possible to reduce the amount of hot water remaining inside the mat 3, and to reduce the load caused by the residual water on the hot bed mat 3.

[Effects of the Invention] In short, the present invention configures the hot water passage path of the hot bed pine in the middle of the path that supplies hot water to the bathtub, that is, the hot bed pine is incorporated in the middle of the path that supplies hot water to the bathtub. It is possible to omit the construction of a dedicated hot-water supply route to the hotbed pine, which significantly reduces costs, and when supplying hot water to the bathtub, hot water can always be supplied to the hotbed pine. It has the advantage of being able to heat the bathroom in a timely manner, thereby providing suitable heating when taking a bath, and also saving energy since the heating of the hotbed pine is done using hot water in the bathtub. Moreover, since a large number of hot water injection holes are provided at the end of the hot water passage in the hot bed pine, the temperature of the hot bed pine is raised by the hot water supplied to the hot water passage, and hot water is sprayed from below like a shower. Direct heating can be performed, and since the hot water injection holes are formed at the end of the path, the hot water injected from the hot water injection holes is at a low temperature after heat exchange in the hot water passage path, and is less likely to cause burns. There is no danger.
