Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to an electric heat-insulating pot with a purifying function that keeps hot water in a container warm.

(Prior Art) Generally, an electric insulation pot has a container for boiling water in a main body, and a heater is attached to the outer periphery of the container.
Then, the water is stored in the container, and the water in the container is heated by the heater to boil it in high temperature hot water to keep it warm, and this hot water is poured out from the hot water outlet through a pump as needed. ing.

(Problems to be solved by the invention) However, there are cases where bacteria contained in water contained in the container or red rust or mold on the inner surface of the container. In such a case, There is a problem that these foreign substances are poured into the hot water from the hot water outlet while being mixed in the hot water, which not only impairs the flavor of the hot water but also impairs hygiene.

This invention was made with this point in mind, and the purpose is to purify the hot water in the container and to pour out sanitary hot water with a good taste. To serve the pot.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve such an object, the present invention relates to an electric heat-insulating pot that heats water contained in a container with a heater to keep it hot water. A circulation path for circulating the water in the container is provided, a pump and a purification filter are provided in the middle of the circulation path, and a valve for opening and closing the circulation path is provided. The water is heated by the heater and the valve is held open until the temperature reaches a temperature just before the deterioration temperature of the purification filter and the water in the container is circulated through the circulation path by the operation of the pump to the purification filter. After the water in the container passes, and the temperature in the container rises above the deterioration temperature of the purification filter, the valve is closed to stop the circulation of water, and the hot water boiled in the container is operated by the pump. Is obtained so as to dispensed through said Shirubeyuro.

(Operation) When the water in the container circulates and passes through the purification filter, the purification filter purifies the water. Then, when the water in the container reaches the temperature just before the deterioration temperature of the purification filter, the circulation of water is stopped, and thereby the thermal deterioration of the purification filter is prevented.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 designates a cylindrical main body, in which a container 2 is housed, and a boiling heater 3a having a large output and a heater 3b for keeping a small output are attached to the outer periphery of the lower portion of the container 2. A circulation path 4 connecting an inner bottom portion of the container 2 and an inner upper portion of the container 2 is formed on the outer side of the container 2, and an electric pump 5 and a purification filter are provided in the middle of the circulation path 4 in a lower portion of the container 2. 6 and 6 are provided side by side. As shown in FIG. 2, the purification filter 6 is formed of a porous hollow fiber membrane made of polypropylene, for example.

A guide pipe 7 is drawn out from the pump 5, the guide pipe 7 stands up along the outer surface of the container 2, and the opening of the tip thereof is provided as a tap 8 at the upper part on the front side of the main body 1. ing.

An electromagnetic first valve 11 is provided in the circulation path 4 between the pump 5 and the purification filter 6, and the hot water guide path 7 is provided.
In the vicinity of the pump 5, electromagnetic second valves 12 are provided respectively.

A lid 13 that opens and closes an upper end opening of the container 2 is rotatably provided at an upper portion of the main body 1, and a vapor escape path 14 that allows vapor in the container 2 to escape to the outside is formed in the lid 13. There is.
A power switch 15 and a hot water switch 16 are provided on the upper surface of the lid 13.

A hot water temperature sensor 18 for detecting the hot water temperature in the container 2 is provided on the bottom surface of the container 2, and a boiling sensor for detecting the boiling of the hot water in the container 2 is provided on the lid 13 based on the steam flowing through the steam escape passage 14. 19 are provided respectively, and further below the container 2, the power switch 15, the hot water switch 16 and the hot water temperature sensor 1 are provided.
8. Based on the signal from the boiling sensor 19, the boiling heater 3a, the heat retaining heater 3b, the pump 4, the first valve 1
A control circuit unit 20 that controls the first and second valves 12 is provided. In addition, 21 is a water level tube which displays the water level in the container 2 outside.

Next, the operation will be described.

The first valve 11 and the second valve 12 are closed during standby before the power switch 15 is turned on. In this state, the lid 13 is opened to store water in the container 2 and then the lid. When the body 13 is closed and the power switch 15 is turned on, the first valve 11 is opened and
The boiling heater 3a and the pump 5 are energized. Then, the water in the container 2 is heated by the boiling heater 3a and gradually rises in temperature.
Through which the water passes through the purification filter 6. Thus, as the water in the container 2 sequentially passes through the purification filter 6, foreign substances such as bacteria, red rust, and mold are removed and purified, so that clean water is obtained.

The water in the container 2 is heated by the boiling heater 3a to a predetermined temperature, that is, the temperature immediately before the deterioration temperature of the purification filter 6,
For example, when the temperature rises to 50 ° C., the temperature is detected by the hot water temperature sensor 18, and in response to this detection, the first valve 1
1 is closed, and the pump 5 is de-energized.
Therefore, water that has risen to a temperature that deteriorates the purification filter 6 does not flow through the purification filter 6,
Therefore, deterioration of the purification filter 6 is prevented, and an appropriate purification function is maintained for a long period of time.

The water in the container 2 is further heated by the boiling heater 3a to boil, and this boiling is detected by the boiling sensor 19,
Based on this detection, the boiling heater 3a is de-energized,
Instead, the holding heater 3b is energized, and the water in the container 2 is kept warm as high-temperature hot water of about 96 ° C. by the warming heater 3b.

When the hot water outlet switch 16 is operated under such a state, the pump 5 is energized and the second valve 12 is activated.
Is released. Then, by the operation of the pump 5, the hot water in the container 2 is sequentially poured out from the hot water outlet 8 through the second valve 12 and the hot water guide path 7. This hot water has been purified by the purification filter 6 in advance, so that it can be used for drinking and the like as clean and tasty hot water in which foreign substances such as bacteria and red rust are not mixed.

[Advantages of the Invention] As described above, according to the present invention, when boiling water, the water in the container can be circulated through the purification filter to be purified, so that a sanitary hot water with good flavor can be kept warm. Since water having a temperature lower than the deterioration temperature passes through the purification filter, thermal deterioration of the purification filter is prevented and an appropriate purification function is maintained for a long period of time. There is an advantage that can be held.
