JPS5839309Y2 - Floor device for both Japanese and Western rooms - Google Patents

Description

[Detailed explanation of the invention] This invention relates to a floor heating system for both Japanese and Western rooms.
To provide a system that heats a room from below by installing a heating frame after removing two floorboards or removing floorboards of similar dimensions in a Western-style room, and using hot water pipes with heat sinks housed within the frame.

Conventionally, heating devices mainly heat the human body directly,
There are things that warm the indoor air, things that warm the floor, etc.

It is common knowledge that a device that heats the floor heats all or most of the floor surface of the room.

This idea goes against common sense; for example, in a four-and-a-half tatami room or eight tatami room, for example, one tatami mat is used, and in a ten tatami room, the two tatami mats are removed, and then a heating frame of the appropriate size is installed.

Traditionally, this was a radiator for steam heating placed against the wall of a Western-style room,
This is a new type of heating that resembles the recent screen-shaped electric heating board, which is wider and lower in temperature, and inserted into the tatami mats on the floor of a Japanese-style room, and the heating heat source is placed at the bottom of the room to increase heating efficiency. It is something.

Next, the configuration and implementation of this invention will be explained with reference to the drawings.

Figures 1 and 2 show the heating frame 10 of the Japanese-style room floor heating system of this invention.
An example is shown below.

As mentioned above, the heating frame 10 has a size suitable for being laid after removing 12 tatami mats in a Japanese-style room, and has a size suitable for laying down after removing 12 tatami mats in a Japanese-style room, and has a heating frame on the top surface. A foamed resin heat insulating board 1 having a plurality of grooves 8 arranged in parallel, each having a depth equal to or more than half the thickness of a tatami mat, a width greater than this depth, and a length not reaching the periphery.
, a hot water pipe 3 in which straight pipes placed one by one in each groove 8 are connected by a curved pipe, etc. A fin material attached to the entire length of the straight pipe in each groove 8, which is wider than the width of the groove 8. 2 groups of rectangular heat sinks with a small width and the upper and lower edges bent at right angles to a height equal to the groove depth, 1 heat insulating plate
These include a metal top plate 5 that rests on the entire top surface and also on the upper edge of each heat sink 2, hot water equipment 6, 7 that circulates hot water through the hot water pipes 3, and the like.

In this example, the heat insulating board 1 is surrounded by an outer frame 4.

The equipment for circulating hot water through the hot water pipe 3 is a pipe 6 and a water heater 7, which are simply illustrated in FIG.

The heat insulating board 1 of this embodiment is made of urethane foam, and its hardness is matched to that of tatami mats.

A groove material for creating a groove 8 is floated and supported in a surface-treated steel outer frame 4 having the required dimensions, a hot water pipe 3 is placed in this, both ends of the groove material are closed, and urethane material is poured in and heated. Then, a heat insulating board 1 made of urethane foam was formed.

Alternatively, the hot water pipe 3 may be bent later so that the shape of the groove 8 matches the bending of the hot water pipe 3 so that the hot water pipe 3 is accommodated in the shaped groove 8.

In FIG. 1, the curved portion of the hot water pipe 3 is buried in the heat insulating plate 1, but it is exposed in the curved groove.

It goes without saying that the pipes connecting the hot water pipes 3 that have entered the parallel grooves of the heat insulating board 1 may be of a parallel type instead of a series type as shown.

Since two groups of heat sinks are attached to the hot water pipe 3, a large amount of heat from the hot water is trapped in the groove 8, and most of the heat spreads into the metal upper plate 5 and is radiated upward, that is, indoors.

The hot water heated to around 60°C is sent to the water heater 7 using the same heating frame 10 but with two groups of heat sinks attached to the hot water pipes 3.
When I compared the temperature of the water returned to the water heater 7 with one without it, the temperature of the water returned to the water heater 7 was 2 to 3 degrees Celsius different.

If you attach the heat sink 2, the amount of heat released from the hot water will increase accordingly.
The warm water returns at a correspondingly lower temperature.

Note that the hot water pipe 3 was made of steel, and the heat sink 2 was made of aluminum.

The heat sink 2 shown in FIG. 3 is provided for pressurization from above.

The method of connecting the hot water pipe 3 and the hot water pipe 6 can be left to the designer, but if you use a stove with the water heater 7 in the same room, insert the pipe from the top of the heating frame 10 and connect the water heater 7 in another room. If it is taken from the floor, it is better to raise the pipe from under the floor to the heating frame 10.

The metal upper plate 5 of the heating frame 10 is a galvanized steel plate in this example, and of course, a receiving overlay, a carpet, etc. is laid on it, so it does not interfere with walking, and the large surface area of its fibers becomes a heat radiation surface.

The above examples were obtained through repeated improvements and experiments.
- Satisfactory results were achieved in the long-term winter experiment.

This idea turns part of the floor of a Japanese-Western room into a heat-radiating surface that matches the size of the tatami mats.

This provides a new form of heating.

It does not dissipate high heat from a small area like conventional heating equipment, nor does it heat the entire floor to the extent that it does not cool down.
The heat dissipation area between the two warms the room from below at an intermediate temperature.

In a Japanese-style room, except for two tatami mats, a heating frame of the same thickness of this invention is placed, so the heating frame is a mass-produced product, can be installed with simple construction, and has a good appearance and livability.

In terms of performance, relatively wide grooves are arranged in parallel on the top surface of the insulation board, and the inside of the grooves is heated by hot water pipes with heat sinks, so it is better than conventional floor heating where the bare hot water pipes are submerged in the insulation material. You can get several times the heating effect compared to.

This made it possible to provide a heat radiation amount suitable for the new heat radiation area of two tatami mats.
