Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a water supply and drainage device for a pot placed on a heating stand, such as an inner pot for a buckwheat stove.

(Conventional technology and its problems) When boiling soba, udon, etc. in a soba oven,
Because the hot water in the inner pot gets dirty with the slimy noodles, I use it 2-3 times a day.
The water has been replaced twice. Also, at the end of the day, it is common to keep a glass of clean water for the next day.

If you neglect to replace the water and use dirty water for a long time, the level of boiling of the noodles will vary depending on the degree of dirtiness, and the boiling time will be inconsistent, resulting in the difference in the taste of the noodles or the unique characteristics of the restaurant. There is also the problem of not being able to produce the taste of the food. Furthermore, a hot water film forms on the inner surface of the inner pot, and when it sticks to the inner pot due to heating, a cavity is formed between the inner pot and the hot water film, and the hollow part becomes an empty state. may cause damage. This makes it necessary to replace the water.

However, when discarding the hot water in the inner pot, the inner pot must be lifted, which requires considerable effort. For example, in a commercial soba stove, the cast iron pot weighs approximately 20 kg, and the amount of hot water inside the pot is approximately 45°C (approximately 80°C), making lifting the pot a labor-intensive task.

Therefore, the present invention provides a water supply and drainage device with a simple structure that allows the hot water in the inner pot to be easily discarded while it is placed on the side stove without lifting the inner pot, and that does not use hot water or suction power such as a pump. The purpose is to Of course, the present invention can be applied to pots for various uses other than buckwheat stoves.

(Means for Solving the Problem) In order to achieve the above object, the present invention branches out from a water supply pipe that communicates with a water supply source, and one side is connected to a faucet pipe that can supply water to a pot placed on a heating stand. , the other is connected to a drain pipe that hangs down to a position below the placed pot, and a valve for opening and closing at least the drain pipe is installed in the middle of this pipe and at a position lower than the water supply surface of the placed pot. The water supply and drainage device for a pot is characterized in that the faucet pipe has a structure in which an extension pipe long enough to reach the inner bottom of the pot is detachably attached.

In addition, it is preferable to install the opening/closing valve of the pipe in at least two places, one on the water supply side of the above-mentioned branch and the other on the drain pipe at a position lower than the pot water supply surface. However, it is possible to use a two-stage switching valve provided at this branching part that allows water to flow through the faucet side and shut off the water supply side, or a three-stage switching valve that allows water to flow through the faucet side, water through the drain side, and shuts off the water supply side.

(Function) The water supply and drainage of the pot by the pot water supply and drainage device described above is carried out as follows.

Normal water supply to the kettle when the kettle is in use is carried out by removing the extension pipe from the faucet pipe, closing the drain pipe, and communicating the water supply pipe with the faucet pipe.

To drain water from the pot, connect an extension pipe to the faucet pipe and position the end of the extension pipe at the bottom of the pot. Fill the pot with water until it reaches its full level, then close the water supply pipe and immediately open the drain pipe. For example, since the pot, extension pipe, and drain pipe are all filled with water up to the position of the drain pipe opening valve located below the water surface of the pot, water is automatically drained using the siphon principle.

When water supply, washing, and drainage are repeated, the drain pipe is closed, the water supply pipe and the faucet pipe are connected to each other, water is supplied to the kettle, the kettle is washed, and then the above-mentioned draining operation is performed.

(Example) Next, an example of the present invention will be explained using a soba stove shown in the drawings. The buckwheat stove shown here has a known configuration in which an inner pot a is installed in the center, a combustion chamber b is formed in the lower part of the inner pot, and a copper pot c is formed around the inner pot.

At the rear corner of this buckwheat stove, as shown in FIGS. 1 and 2, a water supply and drainage device 1 for the inner pot is provided, and its configuration is as follows.

A water supply pipe 71 is branched and connected from the middle of the water supply pipe 3 extending from the rear wall of the buckwheat stove, and an on-off valve C is provided in the middle of the water supply pipe 71, the tip of which is for automatic water supply to the copper pot c. Tank 7 is connected. On the other hand, the water supply pipe 3 is provided with an on-off valve A on the outflow side of the branch part, and a faucet 21 at the tip of which is equipped with a faucet 21 capable of supplying water to the inner pot a via a cheese joint 5. An inner pot a to which a pipe 2 is rotatably connected and a drain pipe 4 is placed on the other side.
The length is connected to a lower position. The faucet 21 of the faucet pipe 2 is designed to be able to be detachably connected to a flexible extension pipe 6 having a length such that its tip 61 reaches the inner bottom of the inner pot a. An on-off valve B is arranged in the drain pipe 4 at a position lower than the water supply level when water is supplied to the inner pot a,
The lower end of the drain pipe 4 serves as a drain port 41.

When supplying water to the inner pot a for boiling buckwheat noodles, close the valve B of the drain pipe 4 and open the valve A of the water supply pipe 3 without connecting the extension pipe 6 to the faucet pipe 2. Water flows out through the faucet 21 of the faucet pipe 2. Therefore, for normal water supply, valve B is kept closed and valve A is
You only have to open and close it. When replacing the hot water in the inner pot a, connect the extension pipe 6 to the faucet 21, position its tip 61 at the inner bottom of the inner pot a, and then open the valve A and replace the water supply pipe 3 and the faucet. All pipes leading to pipe 2, extension pipe 6, and valve B are filled with water to increase the amount of hot water in the inner pot, and then immediately close valve A and open valve B of drain pipe 4.
Alternatively, if you open valve B and immediately close valve A, the position of valve B is set lower than the water level in the inner pot, so the siphon principle works and the hot water in inner pot A flows through the extension pipe 6, The water is drained through a faucet pipe 2 and a drain pipe 4. Moreover, the tip 61 of the extension tube 6
is located at the inner bottom of the inner pot a, and the drain port 41 of the drain pipe 4 is located lower than the bottom of the pot, so all the hot water in the inner pot a is drained. After draining,
When rewashing the inner pot a, it is sufficient to open the valve A and then close the valve B, or operate the reverse operation to supply water into the inner pot and repeat the above operation. Valve B
If you open valve A while keeping it open, you can also clean the inside of the piping.

By providing the above-mentioned water supply and drainage device 1 in a soba stove, the hot water in the inner pot a can be easily discharged, and there is no need to lift the inner pot and discard the hot water as in the conventional method.

Note that the extension pipe 6 connected to the faucet 21 may or may not be a flexible pipe, and its shape is not limited.

Next, another example of the water supply and drainage device 1 for the inner pot is shown in the third example.
As shown in the figure. This is because a valve D, which combines the functions of both the valve A of the water supply pipe 3 and the valve B of the drain pipe 4 in the above embodiment, is provided at the connection part of the three pipes, and
The valve D is set at a lower position than the water supply level of the inner pot. The valve D can perform two operations, ie, closing the drain pipe 4 and communicating the water supply pipe 3 with the faucet pipe 2, or closing the water supply pipe 3 and communicating the drain pipe 4 with the faucet pipe 2, by switching only one valve. Either a two-stage switching valve that can be operated or a three-stage switching valve that connects the water supply pipe 3 to the drain pipe 4 in addition to the above two operations can be installed.

In a water supply and drainage system equipped with a two-stage switching valve, when supplying water to the inner pot a, an extension pipe 6 is attached to the faucet pipe.
It is sufficient to connect the water supply pipe 3 and the faucet pipe 2 by turning the valve D without connecting them.On the other hand, when replacing the hot water in the inner pot a, connect the extension pipe 6 to the faucet pipe 2, and connect the extension pipe 6 to the faucet pipe 2. After positioning the part 61 at the inner bottom of the inner pot a, turn the valve D once to fill all the piping leading to the water supply pipe 3, faucet pipe 2, and extension pipe 6 with water, and fill the inner pot a with hot water. If the water level is increased, and then immediately turn valve D to close water supply pipe 3 and at the same time connect faucet pipe 2 and drain pipe 4, the position of valve D is set lower than the water level in inner pot a. Therefore, the siphon principle works, and the hot water in the inner pot a is drained through the extension pipe 6, the faucet pipe 2, and the drain pipe 4.

In a water supply and drainage system equipped with a three-stage switching valve, the water supply and drainage operations can be performed in the same way as in the case of the two-stage switching valve described above, and in addition, the water supply pipe 3 and the drain pipe 4 can be connected with the faucet pipe 2 closed. As a result, the inside of the drain pipe 4 can also be cleaned.

In addition, if water supply and drainage to the inner pot a is performed by one valve D as shown in Figure 3, water will pass through the same valve for both water supply and drainage, but as shown in Figures 1 and 2. When using two valves A and B, drainage will not enter between valve A and fitting 5, so
If there is no risk of contaminating the valve A and the possibility of contamination of the water source is taken into consideration, it is preferable to use a configuration of two or more valves as in the embodiments shown in FIGS. 1 and 2.

(Effects of the invention) According to the invention, it is possible to easily supply and drain water to the pot by attaching and detaching the extension pipe and operating the valve, so there is no need to lift the heavy pot and discard hot water as in the past. Helps save labor when boiling buckwheat. In addition, since the hot water can be replaced easily, it is possible to prevent the hot water from getting dirty, forming a hot water film, and eventually damaging the pot.

The pot water supply and drainage device has a simple structure and does not use power such as a pump, so there is no risk of failure and it can be manufactured at low cost. Furthermore, since it can be manufactured and installed independently of the main body of the soba stove, it can be easily installed in an existing soba stove.
