Description

Apparatus for suppling Warm water and bidet having the same}

The present invention relates to a hot water supply apparatus and a bidet having the same, and more particularly, to a hot water supply apparatus for embedding a heater in the flow path to reach a desired water temperature while the raw water passes through the outer peripheral surface of the heater and a bidet having the same. will be.

Bides, which are widely used in general, adopt a hot water supply type hot water supply system, which is composed of a heat transfer heater and a temperature control device in a storage tank having a storage capacity of about 1.5 liters to 2 liters.

The low-temperature hot water supply system is a method of warming the stored water to a proper temperature with a sufficient time, so it is relatively easy to control and the water temperature rises so high that it is extremely unlikely to be exposed to a burn or the like, while the water in the tank is in a hot water state. There is a high risk of bacterial growth because of stagnation for a long time.

In addition, the low-temperature hot water supply device must consume power to maintain the water temperature even when the bidet is not used, and when cleaning starts, external cold water flows in as much as outflow from the tank. Since the temperature of the washing water decreases as time passes, there is a problem of causing discomfort due to cold water, especially in winter.

1 is a perspective view illustrating a bidet attached to a left toilet, and FIG. 2 is a schematic view illustrating a path through which the washing water is supplied to the nozzle in FIG. 1.

1 and 2, the bidet 10 attached to the toilet seat 1 is coupled to the main body 20, the main body 20, and the seat plate 30 configured to be opened and closed at a predetermined position of the main body 20. It is provided with an operation panel 40 for selecting various functions of the bidet, or to execute the operation, the operation panel 40 is provided with various operation buttons for selecting various functions of the bidet or executing the operation.

In addition, the main body 20 has a nozzle 22 which is located inside the main body 20 in the standby state and is pushed out of the main body 20 by the operation of the operation button to spout the washing water.

That is, the bidet 10 attached to the toilet seat is discharged through the nozzle 22 to the washing water of a predetermined temperature for anal cleaning, etc., it is used for the cleanliness of the individual after the toilet.

On the other hand, the washing water from the hot water supply tank 24 located inside the bidet 10 is a general nozzle for anal cleaning, female genital cleaning by the flow path selection valve 26 driven by a motor and controlled by a control unit It is ejected out through one of the bidet nozzles, and the nozzle cleaning port.

However, in general, the bidet 10 is automatically introduced into the hot water supply tank 24 by the amount of external cold water discharged as the cleaning time elapses, and thus the water temperature inside the hot water supply tank 24 is It continues to fall, and after 1 to 2 minutes, the function as a hot water supply device is remarkably lost, and it adds the function which stops washing automatically in the case of continuous use by this time by restricting washing time normally to about 1 to 2 minutes.

In addition, in order to maintain the temperature of the water in the hot water supply tank 24 even after the cleaning is finished, the control unit continuously monitors the temperature of the water, and when the temperature falls below the reference, the power is applied to the heater 24a. Increase the water temperature again.

This is unavoidable in the hot water supply device of the hot water type in which the bidet 10 is cleaned at an unspecified time, but unnecessary power is consumed, and there is a concern that bacteria may grow when warm water is accumulated for a long time.

In addition, although most bidets 10 allow the user to preset the desired water temperature before use, even if the user wants to change the water temperature, the water is already stored in the hot water supply tank 24. It is not easy to change the water temperature immediately.

It is an object of the present invention to provide a hot water supply device and a bidet having the same so that hot water is constantly maintained within a set range even when used continuously.

The hot water supply apparatus according to the present invention is installed in the inlet pipe so that the flow path is formed between the inlet pipe and the inner wall of the inlet pipe is formed in the inlet and the outlet of the heated water is discharged on one side to the inlet A flow path is formed between the housing having a double pipe structure having an extension pipe which flows along the flow path to the other side of the inflow pipe along the flow path and then flows from the other side of the inflow pipe to the discharge port, and the inner wall of the extension pipe. It is installed in the extension tube to include a heater for heating the water flowing into the housing.

The extension tube may be formed in a screw shape to facilitate heat transfer from the heater unit to water.

The heater unit may include a sheath heater that generates heat by electricity and a power connector installed at both ends of the sheath heater.

The inlet pipe has a locking jaw formed on one side of the inner side and the extension pipe is provided with a seating portion formed on one side, but the seating portion is seated on the locking jaw so that the extension pipe may be installed inside the inlet pipe.

The heater unit may be in contact with at least any portion of the inner wall of the extension pipe.

The heater unit may be spaced apart from the inner wall of the extension tube.

The housing may include a sealing member so that water introduced into the housing does not flow out.

A bidet having a hot water supply device according to the present invention includes a hot water supply device, a cleaning nozzle connected to the hot water supply device to discharge hot water, and a control unit connected to the heater part of the hot water supply device to control the heating amount of the heater part. And a hot water button connected to the controller.

3 to 5, the hot water supply device 100 includes a housing 120 having a double pipe structure and a heater unit 150 installed to penetrate the housing 120. Since the housing 120 is a part in direct contact with water, it is preferable that the housing 120 is made of a material resistant to corrosion. Therefore, the housing 120 is preferably made of copper or stainless steel (SUS) or aluminum alloy.

The housing 120 includes an inlet pipe 130, an extension pipe 140, and a sealing member 122.

The inlet pipe 130 is formed in a hollow cylindrical shape so that the extension pipe 140 may be installed therein, and is provided by the inlet 132 and the heater unit 150 through which water is introduced into one side of the inlet pipe 130. A discharge port 134 through which the heated water is discharged is provided.

In addition, one side of the inner circumferential surface of the inflow pipe 130 is provided with a locking step 136 formed to be in contact with one side of the extension tube 140 installed in the inlet pipe 130. Since the locking jaw 136 is in contact with one side of the extension tube 140 to block the flow path to the outlet 134 side, the water introduced into the inlet 132 is not heated by the heater 150 to the outlet 134. Emissions are prevented.

In addition, one side of the extension tube 140 is seated on the locking jaw 136 so that the extension tube 140 may be installed inside the inlet tube 130.

In addition, an installation groove 137 in which the sealing member 122 is installed is formed inside the inflow pipe 130, and the heater 150 passes through the other end of the inflow pipe 130 and the sealing member 122 is formed. The through hole 138 to be mounted is formed.

The extension tube 140 is formed in a hollow cylindrical shape so that the heater unit 150 can be installed therein, and is formed in a screw shape to facilitate heat transfer from the heater unit 150 to water, that is, to form a spiral flow path.

In addition, the extension tube 140 has a seating portion 142 in contact with the locking projection 136 formed on the inlet pipe 130 on one side. That is, the extension pipe 140 is installed in the inlet pipe 130 is seated 142 is seated on the locking jaw 136. In addition, the seating portion 142 is coupled to the locking jaw 136 so that the water flowing into the inlet 132 is discharged to the outlet 134 directly along the outer circumferential surface of the extension pipe 140 without being heated by the heater 150. Prevent it.

On the other hand, the extension pipe 140 is installed in the inlet pipe 130 so that the flow path is formed between the inner wall of the inlet pipe 130. Therefore, the water flowing into the inlet pipe through the inlet 132 flows to the other side of the inlet pipe 130 through a flow path formed by the inner wall of the inlet pipe 130 and the extension pipe 140. Thereafter, water flows along the inside of the extension pipe 140 from the other side of the inflow pipe 130, and the water exiting the extension pipe 140 passes through the outlet 134 of the housing 120, that is, the hot water supply device 100. It is discharged to the outside.

In addition, as described above, the extension tube 140 is formed in a hollow cylindrical shape having a screw shape. Therefore, since water flowing into the inlet 132 flows in the housing 120 along the screw-shaped spiral flow path, the time for staying inside the housing is extended, thereby being heated more smoothly by the heater unit 150.

The sealing member 122 is provided at both ends of the housing 120 and includes a first sealing member 122a and a second sealing member 122b to prevent water flowing into the outside from flowing out.

The first sealing member 122a is installed in the installation groove 137 formed at one side of the inflow pipe 130 to prevent the water from flowing out. In addition, the first sealing member 122a includes a coupling hole 122a ′ through which the heater 150 is coupled.

The second sealing member 122b is coupled to the through hole 138 formed at the other side of the inflow pipe 130 to prevent water from flowing out of the inflow pipe 130 at the other side of the inflow pipe 130. In addition, the second sealing member 122b includes an installation hole 122b ′ through which the heater 150 is coupled.

That is, water is prevented from flowing out of the housing 120 through the first and second sealing members 122a and 122b. In other words, water flowing into the inlet 132 and flowing along the flow path formed by the inner wall of the inlet pipe 130 and the extension pipe 140 is moved from the other side of the inlet pipe 130 to the outside by the second sealing member 122b. Outflow is prevented, and water flowing through the inside of the extension pipe 140 by the first sealing member 122a is prevented from flowing out from one side of the inflow pipe 130.

In addition, the sealing member 122 may be made of a material having an elastic force.

The heater unit 150 is installed inside the extension tube 140 to form a flow path between the inner wall of the extension tube 140 and heats water introduced into the housing 120. Since the heater unit 150 is installed inside the extension pipe 140 to form a flow path, the double flow path is formed in the housing 120, and eventually the housing 120 has a double pipe structure.

In other words, the water flowing into the interior of the housing 120 through the inlet 132 formed on one side of the inlet pipe 130 is the inlet pipe 130 along the flow path formed by the inlet pipe 130 and the extension pipe 140. It flows to the other side of, and flows back to one side of the inlet pipe 130 along the flow path formed by the inlet pipe 130 and the heater unit 150 from the other side of the inlet pipe 130. As a result, a double flow path is formed in the housing 120.

The heater unit 150 includes a sheath heater 152 and a power connector 154.

The sheath heater 152 is disposed inside the extension tube 140 to form a flow path between the inner wall of the extension tube 140 and heats water that is heated by electricity and flows into the housing 120. do.

That is, when water flows into the housing 120, the sheath heater 152 generates heat. At this time, the heat generated from the sheath heater 152 is transmitted to the outside of the extension tube 140 through the water flowing along the flow path formed between the sheath heater 152 and the inner wall of the extension tube 140, the extension of the tube 140 The heat transferred to the outside is transferred to the flowing water through the flow path formed by the inner wall of the extension pipe 140 and the inlet pipe 130 to heat the water primarily.

Thereafter, the water flowing through the flow path formed between the sheath heater 152 and the inner wall of the extension tube 140 is secondarily heated by the heat generated from the sheath heater 152.

That is, since water flows inside the housing 120 having the double pipe structure, the water is more surely heated by the sheath heater 152. Therefore, even when hot water is continuously used, water can be supplied within a set temperature range. In other words, the temperature of the water can be maintained within the set temperature range.

In addition, since the extension pipe 140 is formed in a screw shape, the flow path formed between the sheath heater 152 and the inner wall of the extension pipe 140 forms a screw-shaped spiral flow path. Therefore, the time for water to stay in the flow path formed between the sheath heater 152 and the inner wall of the extension tube 140 is extended, so that the water can be heated more easily by the sheath heater 152.

The heating of the water by the sheath heater 152 as described above is not only when the sheath heater 152 is mounted to contact each other at least in part with the inner wall of the extension tube 140, but the sheath heater 152 is extended to the tube 140. It would also be possible to be mounted so as to be spaced apart from the inner wall of the.

That is, the drawing shows that the sheath heater 152 is in contact with the inner wall of the extension tube 140, but is not limited to this, the sheath heater 152 may be disposed to be spaced apart from the inner wall of the extension tube 140.

On the other hand, the sheath heater 152 may be mounted such that at least any portion of the inner wall of the extension tube 140 is in contact with each other. In this case, when the sheath heater 152 generates heat to heat water, heat transfer by conduction occurs at a portion where the inner wall of the sheath heater 152 and the extension tube 140 contacts, and eventually heat generated from the sheath heater 152. The more smoothly transmitted to the outside of the extension tube 140, the water flowing in the flow path formed between the extension tube 140 and the inner wall of the inlet tube 130 can be heated more smoothly.

In addition, the sealing member 122 is coupled to both ends of the sheath heater 152, one end of the sheath heater 152 is coupled to the coupling hole (122a`) of the first sealing member (122a), the other end of the second seal It is coupled to the installation hole 122b` of the ring member 122b. This prevents the power connector 154 and the water in contact.

The power connector 154 is installed at both ends of the sheath heater 152 and is connected to a power supply (not shown) to serve to heat the sheath heater 152. That is, the power connector 154 is installed in the sheath heater 152 so as to be disposed outside the housing 120, and when power is supplied to the power connector 154, heat is generated in the sheath heater 152 to heat the water. .

Hereinafter, the bidet 200 having the hot water supply device 100 according to the present invention as described above will be described with reference to the drawings.

6 is a schematic configuration diagram showing a bidet equipped with a hot water supply device according to the present invention.

That is, the controller 240 normally does not provide power to the power connector 154, and when the signal of the hot water button 260 is input, different power is supplied to the power connector 154 according to the signal of the hot water button 260. The temperature of the hot water is controlled by providing the sheath heater 152 to have a different amount of heat.

The temperature of the hot water discharged through the cleaning nozzle 220 may be set by the user as needed.

Hereinafter will be described the action of the bidet is provided with a hot water supply apparatus according to the present invention.

When the user presses the hot water button 260, the control unit 240 provides power to the power connector 154 according to the signal of the hot water button 260 to cause the sheath heater 152 to heat up.

At this time, water is filled in the housing 120 of the hot water supply device 100, and the water is heated by the sheath heater 152. When heated water, that is, hot water is discharged through the cleaning nozzle 200, water is introduced through the inlet 132 provided on one side of the inlet pipe 130 as much as the discharged water.

Inflowed water flows to the other side of the inflow pipe 130 along a flow path formed between the inner wall of the inflow pipe 130 and the extension pipe 140. At this time, since the sheath heater 152 is in a heat-generating state, heat generated from the sheath heater 152 is transferred to the water flowing along the flow path formed between the inner wall of the inlet pipe 130 and the extension pipe 140 to primarily transfer water. Heated to.

However, the sheath heater 152 that generates heat is in contact with at least a portion of the inner wall of the extension tube 140, so that the heat generated from the sheath heater 152 is outside of the extension tube 140, that is, of the inlet tube 130. It is more easily transmitted to the water flowing along the flow path formed between the inner wall and the extension pipe 140.

Water flowing to the other side of the inlet pipe 130 then flows to one side of the inlet pipe 130 along the flow path formed by the inner wall of the extension pipe 140 and the sheath heater 152. At this time, heat is generated from the sheath heater 152 and the water is heated once again. That is, the water is secondarily heated while flowing along the flow path formed by the inner wall of the extension pipe 140 and the sheath heater 152.

By the way, the extension tube 140 is formed in a screw shape, the flow path formed by the inner wall of the extension tube 140 and the seat heater 152 is also formed in a screw shape.

Accordingly, water flows to one side of the inlet pipe 130 along the flow path formed in the screw shape, and water may stay longer in the flow path not formed in the screw shape in the flow path formed in the screw shape, and thus the sheath heater 152. Can be heated for longer.

As described above, the water flows through the inside of the housing 120 having the double pipe structure including the inlet pipe 130 and the extension pipe 140, so that the water is heated more reliably. In addition, the extension tube 140 may be formed in a screw shape so that water may flow along the flow path formed in the screw shape, and thus may be heated by the sheath heater 152 for a longer time.

The heated water, that is, the temperature of the hot water can be maintained within the set temperature range, hot water that can be maintained within the set temperature range can be discharged through the cleaning nozzle.

In addition, by configuring the heating element with the sheath heater 152, the installation cost can be reduced and the heat resistance can be improved.
