Description

[0001] The present invention relates to a thermostatic water bulb for cold and hot water,

The present invention relates to a water inlet for cold and hot water, and more particularly, it relates to a water outlet for cold / hot water, more specifically, it can improve the structure of a water outlet to automatically water a water of a desired temperature and use it. Which is used for collecting water.

A common faucet is a device for supplying or blocking water, installed in a sink, sink, bathtub, etc. By using a lever or a button provided on the body connected to the water pipe, the flow path is opened and closed to regulate the flow rate, It is a device to flood.

In addition, the water bulb has a variety of types. Depending on the form, it may be connected to one water pipe to supply only cold water or hot water, to connect two water pipes to supply both cold water and hot water, A shower or the like, and a lever type, a button type or a rotating type depending on the operation type. Depending on the material, it is made of various kinds such as steel, copper alloy or stainless steel depending on the use and installation place.

Such a water outlet is connected to a water supply pipe embedded in a place requiring water such as a home or a public place, and the temperature is controlled by adjusting the temperature, flow rate and flow rate of the water supplied by the operation of the lever.

However, a water bulb which is generally used does not directly discharge water of a desired temperature.

This is because the temperature of the hot water supplied to the hot water pipe itself is not constant, or the hot water in the hot water pipe cools down after a certain period of time without flushing the hot water.

Therefore, when hot water is used, the user directly turns the control lever or the like to adjust the water temperature, or uses the water after flowing the water until the cold water in the hot water pipe is completely flooded. In the case of the former, when the lever is suddenly operated There is a risk of getting burned. In the latter case, the water is used without water, which is a major cause of waste of water.

As a means for controlling the water temperature of the water discharged from the water inlet, a Korean Registered Utility Model No. 0287692 discloses an apparatus for automatically adjusting the water temperature by providing a solenoid valve controlled by an electronic controller in the water inlet.

In Korean Patent No. 1273984, a temperature sensor is installed in a water tube and the temperature of the water which is sensed by the sensor is displayed on a digital display unit installed outside, so that the user can check it in real time and adjust the water temperature .

However, the devices disclosed in the above documents can automatically adjust the temperature to flood the water. As mentioned above, there is no mention of the treatment of the water which is cooled in the hot water pipe. Therefore, the problem that the temperature is not automatically controlled and the water is flowed before the water is completely discharged is still left, In addition, since electronic devices are used to control the temperature of water, proper installation of waterproofing measures to prevent electric shock as well as the cost of the electronic device itself is required in installing such electronic devices in a water- There is an excessively required problem.

In addition, there is a possibility of malfunction and malfunction.

1. The present invention In the embodiment  Automatic temperature control for cold / hot water A light bulb  How it Works

Hereinafter, the operation principle of the thermostatic water heater for cold / hot water according to the present invention will be described with reference to FIG. 3 and FIG.

When the control lever 10 is lifted upward, the control bar 31 of the flow path opening / closing unit 30 is operated and the lid 40 and the upper plate 100 connected to the flow path opening / The cold water pipe, the water pipe and the water pipe are opened (see the dotted line in FIG. 3).
That is, the control bar 31 connected to the upper control lever 10 is operated in the left and right direction according to the vertical movement of the control lever 10. Thus, the flow path switching unit 30, the lid 40 and the upper plate 100 The water pipe 220, the cold water pipe 230, the water pipe 240, and the water pipe 250 are opened and closed.

When the control lever 10 is rotated, the upper plate 100 is rotated so that the hot water pipe 220 and the cold water pipe 220, which are connected to the lower plate 200 by the flow control unit 120 located in the upper plate 100, (See solid lines in FIG. 3 and FIG. 4), so that hot water and cold water are mixed in the lid 40.

4, the rate at which the hot water pipe 220 and the cold water pipe 230 are controlled by the flow rate controller 120 is defined as a ratio of X: 1-X And the hot water and the cold water are mixed according to the ratio.

The hot water flows into the hot water tank 300 through the hot water tube 221 and the bimetal 420 in the hot water tank 300 operates according to the temperature of the hot water to rotate the connected inner shaft 400, The temperature of the lower plate 200 connected to the upper end of the heat exchanger 400 is automatically regulated (refer to the one-dot chain line in FIGS. 3 and 4).

In detail, when the temperature of the mixed water is low, the bottom plate 200 rotates in a direction to further open the hot water pipe 220 to increase the hot water inflow amount. When the mixed water is further rotated in the hot water direction, the water pipe 240 is opened, The mixed water flows out to the drain pipe 240. When the temperature of the hot water is high, the bottom plate 200 rotates in a direction to further open the cold water pipe 230 to increase the inflow amount of the cold water so that the temperature of the mixed water is kept constant .

The mixed water whose temperature is automatically maintained in the lid 40 is supplied to the user through the water tube 250.

That is, the upper plate 100 operates the rotating lever 10 by the user, so that the lower plate 200 is automatically rotated by the bimetal 420 to adjust the temperature of the mixed water.

On the other hand, the water drained to the drain pipe 240 is used not only as sewage but also for other purposes by being collected in a separate tank (not shown).

As described above, the thermostatic water heater for cold / hot water according to the present invention automatically adjusts the temperature by using the bimetal, so that the user can water the hot water of the desired temperature, drain the water that is cooled in the water outlet, collect water separately, It is possible to use the hot water conveniently and prevent water waste in the hot water pipe which has been thrown away from the existing water pipe, thereby saving water resources.

In addition, since it is composed of mechanical parts, the installation and maintenance cost is greatly reduced, and the practical application possibility is high and the possibility of malfunction is low.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments described above. It will be apparent to those skilled in the art that numerous modifications and variations can be made in the present invention without departing from the spirit or scope of the appended claims. And equivalents should also be considered to be within the scope of the present invention.
