Description

Hot water purifier {HOT-WATER PURIFYING APPARATUS}

The present invention relates to a hot water purifier, and more particularly, a hot water purifier in which a hot water once warmed is always circulated in a bathtub of a general household to purify, insulate and sterilize the hot water.

As said hot water purifier, various forms are shown. They are basically all built in a device body having an inlet and an outlet, a purifying unit for purifying hot water, a heater unit for keeping warm water, and a pump for circulating hot water. have.

In the conventional hot water purifier, each of the above components is housed in a separate case as a separate part, and each is connected by a hose connection and assembled in a main body case. In addition, the filter medium such as natural stone in the purification section is often used repeatedly, and in this case, a cumbersome operation of taking out the filter medium from the storage container, washing it, and then putting it back into the storage container is required.

As described above, in the conventional hot water purifying apparatus, since the effort for the hose connection in the assembly of the parts and the extraction and recharging of the filter medium in the filter medium cleaning are required, the present invention has no such drawbacks. In other words, it is an object of the present invention to provide a warm water purifying device which is easy to assemble, saves the hose connection time between parts, and can easily wash the filter medium.

The present invention solves the above problems with a hot water purifier, comprising a heater part, a sterilizing part, a purifying part, and a circulation pump, wherein the heater part, the sterilizing part, and the purifying part are assembled in one inner case. . Preferably, the filter medium in the purifying part is filled in a basket container through which water can pass through the whole surface, and the basket container can be attached to and detached from the purifying part, and the upper and lower parts of the heater part and the purifying part A water temperature sensor is placed in the drainage channel from the outlet.

(Example)

Embodiment of this invention is described based on an accompanying drawing. 1 shows an example of the appearance of the warm water purifying apparatus according to the present invention, the main body case 1 has a detachable upper cover 2, on the front of the main body case 1, restart switch, hot water temperature setting The switch panel 3 provided with a switch, a liquid crystal display part, etc. is provided. In addition, the inlet 4 and the outlet 5 are arranged on the bottom surface of the main body case 1 (see FIG. 3), and the inlet 4 is a recovery hose 6 having an absorption unit at the front end of the tub. Is connected, and a return hose (7) having a suction unit is connected to the water outlet (5) at the tip leading into the bathtub.

In the main body case 1, a heater section, a sterilization section and a purification section are provided, which are pre-assembled in one inner case 8 which is integrally molded. 4 and 5, the inner case 8 includes a heater tank 9 having heating means, a sterilization tank 10 having sterilizing ultraviolet lamps, and a purification tank containing filter material ( 11) The upper surfaces of these tanks 9 to 11 are openable.

In the heater tank 9, a heater unit 9a is assembled, and an auxiliary tube 9b extending to the water inlet 4 is attached to the bottom surface thereof. By the action of the circulation pump 16 to be described later, the hot water in the bath that is pumped up through the recovery hose 6 flows into the heater tank 9 through the auxiliary tube 9b from the inlet 4 and flows upward. . The heater tank 9 and the sterilization tank 10 communicate with each other upwardly (communication part 12), and the hot water flowing upward in the heater tank 9 is sterilization tank 10 through the communication part 12. Flows into.

In the sterilization tank 100, an ultraviolet lamp 10a for sterilization is assembled. The sterilization tank 10 and the purification tank 11 communicate with the lower part (communication part 13), and the hot water sterilized while flowing down the inside of the sterilization tank 10 from top to bottom is connected to the communication part 13. Inflow into the lower portion in the purification tank 11, and flows through the filter medium 14 and flows out through the drainage path 15 downward from the upper end of the purification tank (11).

An auxiliary hose 17 connected to the circulation pump 16 is connected to the drain passage 15 so that the inlet 16a of the circulation pump 16 and the drain passage 15 are in communication. The circulation pump 16 may be arranged on the recovery hose 6 side (water inlet side). However, in this case, since the hot water in the inner case 8 is pushed out, a leak accident is likely to occur. Therefore, it is preferable to arrange the circulation pump 16 on the return hose 7 side (outflow side) as in the present embodiment.

The filter medium 14 in the purification tank 11 is stored in a filled state in a basket container 18 with a handle that can be taken out from the surface of the purification tank 11. The basket container 18 is a product made of a resin material which can pass water through the entire surface such as a mesh shape or a porous shape. In the cleaning of the filter medium 14, the basket container 18 is taken out for each basket container 18 and sprinkled with sprayed water. In this way, it can be washed while being put in the basket container 18.

As the filter medium 14, ceramic balls, such as spherical elvan, and activated carbon 20 are used, and by periodically washing them, it is possible to suppress abnormal increase in the amount of purified bacteria in the purification tank 11. In addition, by arranging the silver ion balls 19 in the upper layer portion of the basket container 18, the generation of basic bacteria can be suppressed.

In the hot water purifying apparatus according to the present invention, sufficient safety measures are implemented. That is, in this apparatus, the water temperature sensors 21-23 are arrange | positioned in the upper part and the lower part of the heater tank 9, and the drainage path 15, and the water temperature measurement in those parts is checked at predetermined time intervals, and based on a setting value Control of temperature and circulation is achieved.

At the same time, the presence or absence of an abnormal state is determined by the difference in the detected values in the respective sensors 21 to 23. Accordingly, for example, when a sudden decrease in flow rate is detected, measures such as shutting off the power supply circuit of the heater can be taken to prevent unnecessary combustion of the heater or to prevent idling of the circulation pump.

The present invention is as described above, and according to the present invention, since the heater part, the sterilizing part, and the purifying part are assembled in one inner case in advance, the time for hose connection between these parts is saved, and the connection part is broken. Since there is no occurrence of maintenance, there is no need for maintenance, and thus, there is an effect that the hot water purifier having fewer failures can be efficiently manufactured at low cost.

According to the invention of claim 2, the washing operation of the cumbersome filter medium can be performed relatively easily and easily, thereby increasing the frequency of cleaning, and therefore, there is an effect of suppressing excessive increase in generation of purified bacteria and the like. According to the described invention, it is possible to prevent the occurrence of abnormal combustion such as unnecessary combustion of the heater and idling of the circulating pump, and there is an effect of sufficiently protecting the safety of the user.
