Description

[Detailed description of the invention] The present invention relates to an artificial hot spring device that allows people to enjoy the feeling of hot springs in inns, homes, etc., and is a device that can maintain a uniform state of bath water even when usage conditions change rapidly. This is what we provide.

(Technical background of the invention) Devices equipped with a filtration tank, a heating section, a circulation pump, and an ozone generator are known (e.g.,
2154), and an artificial hot spring device (Jitsugan 60-
187689) is also known. However, this device is good when the conditions of use are almost constant, but when the conditions of use change drastically, such as in hotels, the condition of the bath water does not follow suit and the desired purpose cannot be achieved. .

(Purpose of the invention) This invention provides a new artificial hot spring device that meets the above demands.In addition to automatically maintaining the bathtub temperature and water level constant, the water supply to the bathtub is via a gas heating section and an activation tank. To maintain the uniform condition of bathtub water at all times by supplying hot water to the bathtub.

(Summary of the invention) The structure of the present invention is a purification device in which a filtration tank, a pump, and an activated stone tank are connected in series to a bathtub, and an ozone supply pipe is connected to a secondary pipe of the activated stone tank. A bypass pipe is connected between the pump and the activated stone tank, and the bypass pipe is provided with a sub-pump and a gas heating unit that are operated by the output of a temperature sensor, and the activated stone tank is further provided with a gas heating unit. A water flow sensor that controls the gas heating section and a water supply pipe equipped with a valve that opens and closes depending on the output of the bathtub water level sensor are connected.

(Example) 1 is a bathtub, 2 is a bathtub level, 3 is a main circulation pipe, and both ends of the pipe are opened at the lower and upper parts of the bathtub side wall 1a to form a suction port 4 and a jet nozzle 5. Note that the jet nozzle is always located below the water surface and jets out jet water 2'. 6 is the filter tank, 7 is the main pump,
8 is an activated stone tank. Porous igneous rock (natural ore) containing abundant components of natural hot springs is stored in the activated stone tank 8 as an activated stone, and the activated stone absorbs pollutants in the bath water at a molecular level through its adsorption action. It also has the effect of adsorbing and removing it as a filter material. Reference numeral 9 denotes an ozone generator that generates ozone by corona discharge, and is connected just before the ejection nozzle 5 via an ozone supply pipe 10. Reference numeral 11 denotes a bypass pipe, and both ends of the pipe are connected between the main pump 7 and the activated stone tank 8, respectively. The sub pump 12 is activated by a detection signal from a temperature sensor 13 which is activated when the bath water temperature falls below a specified value, and is stopped by a detection signal from the temperature sensor when the bath water temperature exceeds a specified value. Note that the temperature sensor may detect the temperature of the bath water in the main circulation pipe or the bathtub.

Reference numeral 14 denotes a gas combustion reheating heater that heats the bath water circulating through the heating section 11a of the auxiliary circulation pipe, and in conjunction with the operation of the auxiliary pump 12, a known automatic ignition extinguishing device 15 is activated to ignite the water. The fire is extinguished when the secondary pump is stopped. A water supply pipe 16 is connected to an on-off valve 17 and a water supply heating section 16a, one end of which is connected to a water supply pipe 18, and the other end connected to the activated stone tank 8. Note that instead of this activated stone tank, a bath water supply pipe may be connected to the main circulation pipe between the activated stone tank and the main pump 7. The water level sensor 19
In addition to detecting water level changes using floats or electrodes,
It can be implemented with something that detects water pressure, etc., and its mounting position can be arbitrary. Reference numeral 20 denotes a gas combustion type feed water heater, which is ignited by a known automatic ignition extinguishing device 22 being actuated by a detection signal from a water flow sensor 21 which is activated when a feed water flow occurs in the bath water supply pipe.
The automatic ignition extinguishing system extinguishes the fire when the water supply stops. 23 is a replenishment valve 17 and a feed water heating section 16
A hot water supply branch pipe branched from the water supply pipe 16 between a and 1 is connected to the shower 24 and other hot water supply equipment 25. 26a and 26b are automatic ignition extinguishing devices 1;
This is a gas supply pipe that supplies city gas and other fuel gas through pipes 5 and 22.

By operating the main pump 7, bath water in the bathtub flows into the main circulation pipe 3 from the suction port 4, and is circulated through the filtration tank 6, the main pump 7, the activated stone tank 8, and the jet nozzle 5. During this circulation process, various types of garbage and scaly water in the bath water are removed in the filtration tank 6, and the sterilizing effect of ozone mixed into the jet water 2' from the ozone generator 9 to the bathtub 1 keeps the bath water clean. The bath water can be kept clean and the bath water does not need to be replaced for months to more than a year. During this time, the minerals and ionized trace element components contained in the activated stones in the activated stone tank are eluted into the bath water, creating bath water that is effective for the human body, and can be expected to have therapeutic effects comparable to those of natural hot springs.

When the temperature of the bath water in the bathtub falls below a specified value, the temperature sensor 13 activates the auxiliary pump 12, the bath water is circulated into the bypass pipe 11, and the reheating heater 14 is ignited to heat the bath water. , keep the bath water temperature at an appropriate temperature.

When the bath water level falls below the specified level, water level sensor 1
When the on-off valve 17 is opened by 9 and a water supply flow is generated in the water supply channel 16, the water flow sensor 21 detects this and the water supply heater 20 is ignited to heat the water supply flow. This heated hot water is supplied to the bathtub through the activated stone tank 8 to keep the level in the bathtub constant. Note that when replenishing bath water, if the bath water temperature in the bathtub is below the specified value, the sub pump 12 is operated and the reheating heater 14 is activated.
heating is carried out in parallel. Furthermore, since a water supply flow is generated in the water supply channel 16 by using a hot water supply device other than the above-mentioned bathtub, the water supply heater 20 is ignited and heats the tap water supply to the hot water supply branch pipe 23.
Hot water is then supplied to the shower 24 or other hot water supply equipment 25.

(Effects of the invention) The device of this invention constantly supplies circulating hot water and water to the bathtub via the activated stone tank, so the water quality in the bathtub is kept constant, and it is heated with gas during this supply process, which is different from the conventional device. Since the set temperature can be obtained immediately even though there may be a delay, it can be used comfortably enough not only by large families but also in hotels where the usage time and number of users fluctuate rapidly.
