DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for warming a floor of a hot-water bath such as a bathroom or a shower room for comfortable use.

[0002]

2. Description of the Prior Art When trying to use a bathroom or shower room in cold weather, especially when tiles are used, it is very cold and uncomfortable when walking barefoot because the floor surface is cold.

[0003] Therefore, as disclosed in Japanese Utility Model Laid-Open No. 1-108815, a water spray nozzle for spraying hot water toward the floor of a water bath is provided to warm the upper surface of the floor so that the floor can be used. Heating devices have been conventionally proposed.

[0004]

By the way, the floor of a hot-water bath is formed with an inclined surface which becomes lower toward a drain hole in order to improve drainage. However, the heating efficiency was not good because the hot water nozzle was provided on the high side of the inclined surface and the hot water was blown from the high side to the low side. That is, when hot water is sprayed from the high side of the floor to the low side, the hot water does not spread sufficiently on the floor and flows in a streak along the slope, so that only a small area can be heated and drained in a short time. Since the water flows into the mouth, it does not warm up sufficiently and a large amount of hot water is required. If the water is to be heated over a wide area, it is necessary to provide a large number of spray nozzles, resulting in high costs.

[0005] In particular, if a small amount of hot water is allowed to flow on the tiled floor, only the hot water flows through the joints, and the upper surface of the tile may not be heated at all. There was a problem.

[0006]

SUMMARY OF THE INVENTION A floor heating apparatus for a hot-water bath according to the present invention is intended to solve the above-mentioned problems, and is intended for use in a bathroom, a shower room, or the like having an inclined floor with a gentle drain gradient. By providing a water spray nozzle in the bath room on the downstream side above the inclined floor surface with its outlet facing upstream, the hot water is blown from obliquely above the downstream side on the inclined floor surface. It is a feature.

[0007]

[Function] Hot water sprayed from obliquely above the downstream side on the inclined floor surface flows upward on the inclined floor surface due to its flow, but when it loses its flow, it tends to flow downward by its own weight. The water collides with the hot water flowing upward due to the current and accumulates, and the hot water in that portion rises and the hot water film becomes thick. The hot water escapes to both sides to avoid collisions and flows down. And the heating efficiency is greatly improved.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The bathroom shown in FIGS. 1 and 2 is formed such that the inclined floor surface 2 adjacent to the bathtub 1 has a gentle drain gradient toward the drain groove 3. In addition, a drain port lid 4 is detachably covered on the drain groove 3.

Reference numeral 5 denotes a hot / water mixing faucet provided on the inner wall surface of the bathroom, and reference numeral 6 denotes a multifunctional shower device in which hot water is supplied from the faucet 5 via a hot water supply pipe 7. ,
An operation switch 8, body shower water outlets 9, 9, a hot water discharge port 10, a top shower nozzle 11, mist shower nozzles 12, 12, and a hand shower 14 connected to the tip of a flexible hose 13 are provided. By switching the operation switch 8, hot water can be spouted straight and horizontally from the body shower spouts 9, 9; water can be spouted out of the stagnation hot water spout 10; Mist shower nozzle 12,12
Spray in the form of a mist or hand shower 1
4 and so on. Reference numeral 15 denotes a hanger provided on the bathroom wall to support the hand shower 14.

In the embodiment, the hanger 16 is fixed to the wall surface of the bathroom above the drain 3 and the sprinkler nozzle (in this case, the hand shower 17) is hung on the hanger 16 and the outlet 18 is inclined. By providing the water toward the upstream side of the surface 2, the hot water blown out from the outlet 18 can be blown obliquely upward from the downstream side to the inclined floor surface 2. The hand shower 17 may be provided exclusively for floor heating as described above, but the hand shower 14 may be shared for floor heating by changing the hand shower 14 on a hanger 16.

On the other hand, in the embodiment shown in FIGS. 3 and 4, a sprinkling nozzle 20 is protruded from a wall surface of a bathroom, and a hot water supply pipe 23 and a water supply pipe 2 are provided.
The spray nozzle 20 is disposed on the secondary side of a thermostat mixing valve 21 connected to the solenoid valve 4 through an electromagnetic valve 22, and the electromagnetic valve 22 is opened and closed by an operation panel 26 provided near an entrance door 25 of the bathroom. Is configured to work,
The operation panel 26 has a built-in timer, and the hot water whose temperature is appropriately adjusted by the thermostat mixing valve 21 can be blown out from the sprinkler nozzle 20 by operating the operation panel 26 to open the electromagnetic valve 22 for a certain period of time. I can do it. Note that the same reference numerals in FIGS. 3 and 4 as those in FIGS. 1 and 2 indicate the same components.

The hot water blown out from the hand shower 17 or the outlet 18 of the hot water spray nozzle 20 spreads in a fan shape, hits the inclined floor surface 2 and rises up the inclined floor surface 2 with its flow, loses the flow and returns. When the hot water collides with the incoming hot water, the hot water film in the vicinity of the hot water becomes thicker.

The location of the watering nozzle 20 is of course not limited to this embodiment as long as it is on the downstream side of the inclined floor surface 2. Particularly, the location near the bathtub 1 from the inside of the entrance door 25 is preferred. It is desirable to set the sprinkler nozzle 20 so as to warm up.

[0014]

As described above, according to the floor heating apparatus for a bathtub of the present invention, the hot water is supplied to the inclined floor by providing the sprinkler nozzle on the downstream side above the inclined floor surface and the outlet thereof toward the upstream side. Because it is blown from the downstream side diagonally above the surface side, a thick film of water is formed on the sloping floor surface and the tile surface can be warmed well, and the hot water spreads both outwards. Since it flows down, the inclined floor surface can be heated over a wide area with a small amount of hot water. In addition, since the water spreads out on both sides and flows down, the residence time of the hot water on the floor surface is prolonged, the sensible heat of the hot water can be sufficiently transmitted to the floor surface, and the floor surface can be efficiently heated, so that the bathroom is comfortable even in cold weather There is a beneficial effect that a shower room can be used.
