Description

[Detailed description of the invention] (b) Industrial application fields The present invention relates to a steam generator such as a steam sauna.

(B) Conventional technology Conventionally, as shown in Figure 3, a steam generator for a steam sauna heats and evaporates water by connecting an evaporator (V) with a heat source to a water source (V) such as a water supply. This steam is then led to the bathroom (Ro).

In addition, the steam piping (1) extending from the steam generator (■°)
, 3") are simply opened into the interior of the bathroom (Ro).

(c) Problems to be Solved by the Invention However, in the conventional configuration described above, in order to diffuse steam into the bathroom, the steam generator must generate at least 10% of water.
It does not work unless it is heated to 0℃, and steam pressure is used to eject water vapor into the bathroom.
There is a problem in that the amount of heat consumed is large and the economic burden is large.

Furthermore, since it takes time to heat the low-temperature water from the water source to IOO'C, the rise of steam generation is slow, and it takes a long time after starting the device until you can take a bath.

(d) Means for Solving the Problems In the present invention, a pressurizing stage whose suction side is connected to a hot water storage tank is connected to a pipe provided with a heating means in the middle, and the tip of the F pipe is installed in a bathroom for spraying. Provided is a steam generating device for a steam sauna, characterized in that the device is configured to emit steam by spouting pressurized and heated water from the spray hand r into a bathroom. This is what I am trying to do.

(E) Functions and Effects According to the present invention, water heated and heated by the pressurizing means and the heating means is sprayed in the form of mist from the spraying means, so that even if the temperature is 100°C or lower, steam is not generated. Furthermore, since steam pressure is not required for steam ejection, the amount of heat consumed by the heating means can be reduced and the steam sauna can be operated manually.

In addition, since the hot water stored in the hot water storage tank can be electrically heated to 90'C, steam generation is quick and it is possible to take a bath in a short time after starting the device.

In particular, if you use a hot water storage type electric water heater that uses cheap nighttime electricity for the hot water storage tank, you can operate the steam sauna more economically, and it is also easier to use electric heat with a small calorific value as the heat source. This makes it possible to unify the heat source to electric heat, which is advantageous in terms of installation work and safety.

(f) Examples Embodiments of the present invention will be specifically described with reference to the drawings.

FIG. 1 shows the configuration of a steam sauna (A) equipped with a steam generator (v) according to the present invention, and the steam sauna (A) mainly consists of a bathroom (R) and a steam generator ( ) and a control device f (C).

The bathroom (1?) has an entrance and exit (1), a ventilation hole (2) at the top of the bathroom (R), and a drain port (3) at the bottom.
In the bathroom (R), there is a bathtub (B), a collar (B1) for filling the bathtub (B) with water, a vanity shelf (R1), a sitting area (R3) in the washing area (R2), and a stool (R3) in the washing area (R2). A hot water/cold water mixing faucet (R4) provided on the side wall of the hot/cold water mixing faucet (R4) is provided with a spraying means (N) of a steam generator (■) to be described later on the side wall of the three manual sides of the hot water/cold water mixing faucet (R4).

In addition, as shown in Figure 2, the steam generator (■) is equipped with a temperature sensor (S) that detects the internal temperature of the bathroom and is connected to a control device (C), which will be described later. ), a pressurizing means (P), a heating means (H), a spraying means (N), and piping connecting these.

The hot water tank (4) is a hot water storage type electric water heater that uses inexpensive nighttime electricity as a heat source, and can use a multi-bend burner or the like to supply hot water at about 70°C.

The pressurizing means (P) has a discharge pressure of approximately 5 kg/cd, and its water inlet is connected to the hot water storage tank (4), and its discharge outlet (6 is connected to the heating means (H) through piping (7). ) is connected to the inlet (8).

The heating means (H) winds a heating wire as a heat source around the outer periphery of a metal pipe such as a steel pipe while maintaining insulation, and efficiently transfers the heat generated by the heating wire to the water flowing through the heating means (H). That's what I do.

In addition to the above, a gas burner, an oil burner, or the like can be used as the heat source of the heating means (11).

The spraying means (N) is installed at the bottom of the side wall of the bathroom (R) with the spraying direction diagonally upward, and there is an on-off valve (12) in the middle.
It is connected to the outlet (14) of the heating means (H) via a high-temperature pipe (IB) provided with.

Further, the high temperature pipe (13) is branched upstream of the on-off valve (12), and a drain valve (15) is connected to the tip thereof.

In addition, the hot water mixing faucet (R4) is connected to the hot water storage 11 (4) and the water source (W), and the hot water mixing faucet (R4) is equipped with a Karan (old) for filling the bathtub (B) with water. , faucet (R5)
and the shower (Re) via a manual valve (R8).

The input side of the control device (C) is connected to the temperature sensor (S) installed in the bathroom (R), the operation switch (IB), and the temperature setting switch (17), and the output side is connected to the The pressurizing means (P), the heat source of the heating means (1 ()), and the on-off valve (12) are connected, and when the temperature in the bathroom is lower than the set temperature, the opening degree of the on-off valve (I2) is increased. ,vice versa,
When the temperature in the bathroom is higher than the set temperature, close the on-off valve (12
) is opened to a smaller degree or closed to maintain a constant temperature in the bathroom.

The embodiment of the present invention is configured as described above, and when starting to use the steam sauna (A), first, the on-off valve (1
2) is closed, the drain valve (15) is opened, and the pressurizing means (
P) is activated to replace the low-temperature water in the piping (7) and heating means (H) with high-temperature hot water from the hot water storage tank (4), and to preheat each of the above-mentioned members.

Next, the drain valve (15) is closed, the pressurizing means (P) is stopped, and the heat source of the heating means (H) is energized.
Heat the water inside.

When the temperature of the water in the heating means (l()) rises to about 90°C, the pressurizing means (P) is started, the drain valve (I5) is opened, and the low-temperature water in the high-temperature pipe (13) is drained. Replace with hot water from heating means (H).

Next, the on-off valve (12) is opened, the drain valve (15) is closed, and the spraying means (N) is pressurized to about 5 kgf/cd.
About 500 m1/-1n of hot water heated to about 90°C is sprayed into the bathroom (1?).

The high-pressure, high-temperature water sprayed in this manner quickly vaporizes, so that the interior of the bathroom (R) can be rapidly filled with water vapor.

As mentioned above, since it is sufficient to heat the approximately 70"C vortex from the hot water storage tank (4) to approximately 90°C, the amount of heat consumed by the heating means (H) is small, and it is possible to In addition, unlike conventional methods, the discharge pressure of the pressurizing means (P) is used instead of steam pressure, so no heat is required for the ejection nozzle.
Furthermore, the consumption of heat can be reduced.

In addition, since it is only necessary to heat hot water at about 70°C to 9 (1'C), the steam generation is quick and it is possible to take a bath in a short time after starting the steam generator (■).

Then, the temperature sensor (S) controls the on-off valve (12) and the like to keep the temperature in the bathroom constant.

As mentioned above, by dividing the heating of the water for the generation into two stages and using the hot water storage tank (4) in the first stage, the heating means (
) The amount of heat generated in 1) can be reduced, making it easier to use electric heating with a small amount of heat.

In addition, by using a hot water storage type electric water heater that uses nighttime electricity in the hot water storage tank (4), the steam sauna (A) can be used more economically, and all heat sources can be unified with electricity. This is advantageous in terms of equipment installation and safety.
