Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water supply system for a kitchen, and more particularly, to a kitchen faucet provided with a tap for exclusive use of hot water, from which hot water can be discharged for use in cooking instant foods and the like. It relates to a formed kitchen hot water supply system.

[0002]

2. Description of the Related Art Conventionally, as a system of this kind, there is a system in which a water heater and a water faucet are connected by a hot water pipe, and hot water is supplied from the water heater to the water faucet via the hot water pipe. is there. In this case, conventionally, it has been customary that hot water of about 60 ° C. is supplied from a water heater to about 60 ° C. even at a high human skin temperature even at a high temperature.

[0003]

In the case of cooking instant foods, for example, boiling water of 90 ° C. or higher is usually required. However, a conventional method of obtaining this kind of boiling water is to use a kettle filled with water. It was common to use a stove or an electric pot.

However, stoves and the like have a lower thermal efficiency than a water heater, and have a small amount of heat per unit time. Therefore, conventionally, even when a small amount of hot water required for cooking of instant foods and the like is obtained, when there is no hot water in the pot, it is necessary to boil the hot water with a stove or the like each time. It was easy to increase, and it took time to get hot water.

The present invention has been made in view of such conventional circumstances,
It is a proposal. Therefore, the technical problem of the present invention is:
Hot water suitable for dishwashing, etc., and hot water necessary for cooking instant food etc. can be obtained separately from their own faucets, making it easier to use the sink and comparing to boiling from water with a stove etc. Another object of the present invention is to provide a kitchen hot water supply system formed so as to save costs and reduce time.

[0006]

The present invention employs the following technical means in order to solve the above-mentioned problems.

That is, according to the present invention, as shown in FIG.
A hot water supply system for a kitchen in which a faucet 2 of a sink 1 and a hot water supply 3 are connected by a hot water supply pipe 4, and hot water is supplied from the hot water supply 3 to the faucet 2 via the hot water supply pipe 4. 1 is provided with a tap 8 for hot water separately from the tap 2, and the hot tap 8 for hot water and the hot water supply 3 are provided separately from the hot water supply pipe 4. It is characterized by being connected by a pipe 9 (claim 1).

Here, the hot water specifically means hot water at about 90 ° C. or higher. In the case of the present invention, for example, it is preferable that the hot water is purified by the filters 7 and 17 so that the purified hot water can be supplied to the sink 1, but the present invention is not limited to this.

The present invention also provides a sensor 10 for detecting the temperature of hot water discharged from the hot water faucet 8, and a detection value of the sensor 10 is compared with a set temperature, and when the set temperature is reached, the set temperature is displayed. It is preferable that the display device includes a display 11 that performs the operation (claim 2).

The water heater 3 can instantly boil water, but unlike a pot that discharges stored water, it is impossible to discharge hot water from the beginning of operation due to its nature. . Therefore, when hot water is supplied from the hot water supply 3 to the sink 1, it is inevitable that low-temperature hot water will flow out of the hot water faucet 8 at the initial stage of turning on the hot water supply 3 or at the time of re-hot water supply. This type of system is desirably formed so that the timing of pouring hot water into an instant food or the like can be easily and clearly known.

The present invention described in claim 2 has been proposed in view of such a problem. Therefore, according to the present invention, the temperature of hot water during tapping can be known from the hot water faucet 8, the timing of pouring hot water when cooking instant foods and the like becomes clear, and beverages can be prepared at low temperatures. It can prevent cooking and cooking and can also eliminate waste of waste water.

In the case of the present invention, the position of the indicator 11 is, for example, a faucet 8 for hot water, a back guard portion of the sink 1, or a kitchen wall near the faucet 8. . The display 11 may be incorporated in the remote controller 6 of the water heater 3. When the indicator 11 is provided on the faucet 8, as soon as the set temperature is confirmed, for example, the hot water can be discharged without greatly changing the line of sight or the body direction, and the indicator 11 needs to be attached separately from the faucet 8. Because there is no, the usability is improved.

Further, in the present invention, as shown in FIGS. 6 to 9, it is preferable that the temperature of the rising hot water is displayed stepwise on the display 11 as time elapses.

This is because, in this case, the temperature can be known in real time while waiting for hot water, and cooking can be easily set up. Specifically, as shown in the figure, the display 11 has a temperature display 11a that is provided in a stepwise manner and a light emitting diode (L) provided at a position corresponding to the temperature.
ED) 11b or a liquid crystal display device for sequentially displaying a rising temperature in digital form.

Further, the present invention may be formed with an audio notifying section 14 for notifying by voice that the temperature of the hot water discharged from the hot water faucet 8 has reached the set temperature. .

In this case, the water discharge temperature can be known in real time not only by visual sense but also by auditory sense, so that it becomes easier to understand for not only visually impaired persons but also healthy persons, and the usability is improved.

In the present invention, as shown in FIG. 10, the hot water faucet 8 preferably includes a mounting table 21 for the hot water storage container 20 below the water outlet 8a. (Claim 5).

This is because, in this case, it is possible to prevent a burn due to the splashing hot water.

Specifically, the temperature of the hot water to be discharged is, for example, 3
When the temperature reaches 0 ° C., the corresponding LED 11b lights up,
Each time the temperature rises by 10 ° C., the corresponding LED 11b turns on (see FIG. 7). The cook turns on the switch 15 when the LED 11b corresponding to 90 ° C. is turned on, thereby discharging hot water of 90 ° C.

In the case of the present invention, the display 11 may be configured so that the LED 11b blinks, for example, until each temperature is reached.

Specifically, as shown in FIG. 8, a temperature display 11a is provided at intervals of 10 ° C., for example, from 70 ° C. to 90 ° C., and a corresponding LED 11b is provided beside the temperature display 11a. Then, as shown in FIG. 9, when the temperature of the hot water to be discharged does not reach 70.degree. C., the corresponding LED 11b blinks, and when the temperature reaches 70.degree. For each of the temperatures of 80 ° C. and 90 ° C., a similar operation signal
This is output to the ED 11b.

Is formed so as to be rotatable in the left-right direction about the axis. In this embodiment, the mounting table 21 is formed of a heat-resistant material in a lattice shape so that draining is possible.

When the mounting table 21 is used, before the hot water is discharged, the mounting table 21 is rotated and disposed below the water discharge port 8a. Place the cup, then let the hot water out.
When not in use, the mounting table 21 is rotated and retracted from the upper surface of the water tank 22.

[0038]

As described above, the present invention can be used at about 37 ° C.
A faucet for hot water is provided separately from a faucet for discharging hot water of -60 ° C, and the faucet for hot water and the hot water supply unit are connected by a hot water supply pipe.

Accordingly, in the case of the present invention, not only hot water having a preferable temperature for dishwashing and cooking but also hot water necessary for cooking instant foods and the like can be obtained. Since the required amount of hot water can be obtained instantaneously by the water heater as compared with the case of boiling water, there is an advantage that the time can be shortened and the gas cost can be saved.
