Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water purifying apparatus, and more particularly, to a hot water purifying apparatus for purifying, keeping warm and sterilizing hot water in a general household bath by constantly circulating hot water. Things.

[0002]

2. Description of the Related Art Various types of hot water purifying devices are available. Each of them basically includes a purifying section for purifying hot water, a heater section for keeping hot water, and a pump for circulating hot water in an apparatus body having an inlet and an outlet. It is configured.

[0003] In the above-mentioned conventional hot water purifier, each of the above components is housed as an individual part in an individual case.
Each is connected by a hose connection and incorporated into the main body case. In addition, a filter medium such as a natural stone in the purification unit is often used repeatedly, and in such a case, it is necessary to perform a troublesome operation of taking out the filter medium from the storage container, cleaning the filter medium, and then returning the filter medium to the storage container.

[0004]

As described above, in the conventional hot water purifying apparatus, the hoist for assembling parts is not provided.
The present invention does not have such a drawback, that is, it is easy to assemble and has a hose between parts, since a complicated operation such as connection of the filter medium and removal and refilling of the filter medium when the filter medium is washed is required. It is an object of the present invention to provide a hot water purifying apparatus which can save the trouble of connection and can easily clean a filter medium.

[0005]

The present invention comprises a heater, a sterilizer, a purifier, and a circulation pump.
The above object has been attained by a hot water purifying apparatus characterized in that a tar section, a sterilizing section, and a purifying section are incorporated in one internal case. Preferably, the filter medium in the purifying section is filled in a basket container capable of entirely passing water,
The basket container is attachable to and detachable from the purifying section, and a water temperature sensor is provided at an upper portion and a lower portion of the heater portion and in a drainage passage coming out of the purifying portion.

[0006]

Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an example of an appearance of a hot water purifying apparatus according to the present invention. A main body case 1 has a detachable top cover-2. A switch panel 3 including a temperature setting switch, a liquid crystal display, and the like is provided. A water inlet 4 and a water outlet 5 are provided on the bottom surface of the main body case 1 (see FIG. 3), and the water inlet 4 is provided with a collecting hose provided with a water absorbing unit at a tip extending from the inside of the bathtub. A return hose 7 having a blowing unit at the end extending into the bathtub is connected to the water outlet 5.
Is connected.

In the main body case 1, a heater section, a sterilizing section, and a purifying section are installed, and these are integrally formed.
It is pre-assembled in two internal cases 8. That is, as shown in FIGS. 4 and 5, the inner case 8 includes a heater tank 9 provided with a heating means, a sterilizing tank 10 provided with an ultraviolet lamp for sterilizing, and a purification tank containing a filter medium. 11 is provided. The upper surfaces of these tanks 9 to 11 can be opened.

In the heater tank 9, a heater unit 9a is provided.
And an auxiliary tube 9b extending to the water inlet 4 is attached to the bottom surface thereof. Hot water in the bath tub, which is pumped through the recovery hose 6 by the operation of the circulation pump 16 described later, flows into the heater tub 9 from the water inlet 4 through the auxiliary tube 9b. Through to The heater tank 9 and the sterilizing tank 10 communicate with each other at the upper part (communication part 1).
2) The hot water flowing upward in the heater tank 9 flows into the sterilizing tank 10 through the communication portion 12.

An ultraviolet lamp 1 for sterilization is provided in a sterilization tank 10.
0a is incorporated. The lower part of the sterilization tank 10 and the septic tank 11 communicate with each other (communication part 13), and the hot water sterilized while flowing down the sterilization tank 10 from above to below communicates with the communication part 1.
3, flows into the lower part of the septic tank 11, flows through the filter medium 14, and drains downward from the upper end of the septic tank 11.
Spills through.

An auxiliary hose 17 connected to a circulation pump 16 is connected to the drainage channel 15 so that the water inlet 16a of the circulation pump 16 and the drainage channel 15 are in communication.
The circulating pump 16 may be disposed on the recovery hose 6 side (water inlet side), but in that case, the hot water in the internal case 8 is pushed out, so that a water leakage accident is likely to occur. Therefore, the circulation pump 16 is preferably arranged on the return hose 7 side (water outlet side) as in the present embodiment.

The filter medium 14 in the septic tank 11 is a basket container 1 with a handle that can be taken out from the upper surface of the septic tank 11.
8 is stored. Basket container 18
Is made of resin material such as mesh, porous, etc.
When washing the filter medium 14, the basket container 18 can be taken out of the basket container 18 and immersed in spray water or the like, and can be washed while being kept in the basket container 18.

As a filter medium 14, a ceramic ball such as globular barley stone or activated carbon 20 is used, and by periodically cleaning it, the abnormal increase of the purification bacteria in the purification tank 11 can be suppressed. Further, by disposing silver ion ball 19 in the upper layer of basket container 18, the generation of anaerobic bacteria can be suppressed.

In the hot water purifying apparatus according to the present invention, sufficient safety measures are taken. That is, in the present apparatus, the water temperature sensors 21 to 23 are disposed in the upper and lower portions of the heater tank 9 and the drainage channel 15, and the water temperature measurement in those portions is checked at predetermined time intervals, and the set value is set. Temperature and circulation control based on the

At the same time, the presence or absence of an abnormal state is determined from the difference between the detection values of the sensors 21 to 23. Thereby, for example, when a sudden decrease in the flow rate is detected,
Measures such as shutting off the power supply circuit of the heater are taken in order to prevent the heater from being idle and prevent the circulation pump from running idle.

[0015]

The present invention is as described above. According to the present invention, the heater, the sterilizer, and the purifier are incorporated in one internal case in advance. There is no need to perform hose connection, and there is no need for maintenance because there is no failure at the connection part. Therefore, there is an effect that a hot water purifying apparatus with few failures can be efficiently manufactured at low cost.

According to the second aspect of the present invention, it is possible to relatively easily and easily perform a troublesome cleaning operation of the filter medium, so that the frequency of cleaning can be increased. According to the third aspect of the present invention, it is possible to prevent the occurrence of abnormal situations such as idling of the heater or idling of the circulating pump, and to sufficiently secure the safety of the user. There is an effect that can be protected.
