1 to 8, the instantaneous hot water device for a scrubber according to the present invention is composed of a housing 100 and a heater 200 as a heating part. The heater 200 is provided in a plate shape and is firmly fixed by combining with the housing 100. And therebetween is provided to seal the inside with a packing or gasket not shown.

The housing 100 has an inlet 10 and an outlet 20, and the heat exchanger 30 is a predetermined space between the inlet 10 and the outlet 20 to be heat exchanged with the heater 200. ) Is provided.

The heater 200 is a plate-shaped heater as shown in FIG. 7, and is configured by a coupling structure of a heating element 210, a heat transfer member 201, a lead wire 202, and a conductor 203.

The heating element 210 is a ruthenium series that generates heat when a current is supplied through the lead wire 202, which is printed on one surface of the heat transfer member 201 in a state where a plurality of the heating elements are fired at a high temperature at a predetermined interval. It is composed of a structure.

The heat transfer member 201 is directly attached to the outer surface of the heat exchanger 30 or indirectly attached to the outer surface of the heat exchanger 30 after being printed on one surface of the plate-shaped mounting plate 204 as shown in FIG. 8. It can be configured as a coupling structure of the way, it is preferable to attach directly to the outer surface of the heat exchange unit (30).

In addition, the heat transfer member 201 may be disposed in the flow path 31 in the housing 100, in which case the heat transfer member 201 of the heat transfer member 201 to protect the heating element 210 and the lead wire 202 from the fluid. On the surface, it was made to form an insulating layer by application of an insulating material (not shown).

In this case, the heat transfer member 201 is a plate-shaped plate made of aluminum oxide or stainless steel, but is not limited thereto and may be made of a material such as ceramic or copper having high thermal conductivity.

In addition, the heater 200 may be provided with a heat sink for heat exchange (not shown) to increase the heat exchange efficiency of the heating element 210 with the fluid.

The lead wire 202 is connected to the heating element 210 so that a current can be supplied to the heating element 210, and the conductor 203 is connected to each of the heating elements 210. It is configured to connect both ends of the respective heating element 210 so that the current can be supplied from the same time.

The heat exchanger 30 is provided such that a space having a predetermined thickness is formed in the housing 100 so that the fluid introduced therein can be heat-exchanged at an instant, and a heater 200 having a plate shape is attached to the lower portion thereof.

In addition, the heat exchange part 30 is a zigzag flow path 31 is formed so that the introduced fluid is sufficiently heat exchanged by increasing the heat exchange contact area as shown in FIG. At this time, the zigzag flow path 31 may be solved by forming a partition 32 through which one side of the heat exchange part 30 passes.

As shown in FIG. 3, the housing 100 includes a mixing part 40 having a predetermined space so that the fluid in the laminar flow state divided into the cold water layer and the hot water layer, which are heat-exchanged in the heat exchange part 30, may be uniformly mixed. Prepared. In addition, the mixing part 40 is provided with an inlet 41 so that the fluid heated in the heat exchange part 30 may be introduced.

The diameter of the inlet 41 is formed larger than the diameter of the water outlet 20. The reason is that the fluid introduced through the inlet 41 is larger than the fluid supplied to the scrubber not shown through the outlet 20, so that a constant pressure is formed in the mixing part 40. In addition, a constant pressure is formed and the flow of fluid is stacked to slow the flow rate, thereby increasing the mixing efficiency of the fluid in the mixing part 40.

In the mixing part 40, it is preferable to form an inlet 41 on one side so that the heat-exchanged fluid can be properly mixed so that the vortex is generated. That is, the centerline of the inlet 41 and the outlet 20 is shifted.

In addition, the mixing part 40 may form a predetermined space so that a predetermined amount of the heat exchanged fluid may be fresh inside. And the area of the mixing part 40 is formed smaller than the area of the heat exchange part (30). Therefore, the fluid is properly mixed in the mixing unit 40 is uniform temperature is supplied to the hot water scrubber (not shown) through the outlet 20.

Instantaneous hot water device for a scrubber of the present invention is provided with a plurality of detection unit (50). Since the sensing unit 50 is installed in different sensing positions, it will be described with reference to FIGS. 3 to 5.

The inlet 10 is provided with an inlet sensor 51 to measure the temperature of the introduced fluid as shown in FIG. 4 so as to adjust the amount of heat generated by the heater 200 to a set temperature supplied to the scrubber. That is, by measuring the temperature of the inlet sensor 51, if the temperature is too low, the heat generation amount of the heater 200 is increased, and if the temperature of the inlet sensor 51 is too high, the heat generation of the heater 200 is lowered.

In this case, the inlet sensor 51 is disposed adjacent to the inlet 10 so that the temperature of the fluid flowing into the inlet 10 is sensed. In addition, the inlet 10 is provided to have a predetermined distance to the heat exchanger 30 to prevent the heat exchanged fluid from flowing back and affecting the inlet sensor 51.

In addition, a fuse 52 is electrically connected to the heater 200 to block abnormal overheating.

That is, the fuse 52 is connected to the lead wire 202, and when the heating element 210 is suddenly overheated to detect abnormal overheating, the supply of the current to the heating element 210 is blocked.

In addition, the bimetal 53 is electrically connected to the heater 200 as shown in FIG. 4.

That is, the bimetal 53 is installed at the outlet 20 of the heat exchanger 30 and is directly connected to the heating element 201.

Therefore, when the fluid sufficiently heat exchanged in the heat exchanger 30 is detected before the temperature is introduced into the mixing unit 40, if the temperature is higher than the rated temperature of the bimetal 53, the current supply to the heating element 210 is cut off, and the rated temperature is lower than the rated temperature. Then supply the current.

Therefore, the bimetal 53 is kept at a constant temperature, and the fuse 52 is prevented from overheating.

Here, the safety device fuse 52 and the bimetal 53 may be fastened with a screw using a separate member, but in order to attach more simply and reliably, the high-temperature silicone-based adhesive having excellent thermal conductivity ( (Not shown), it is desirable to ensure the performance, such as insulation performance, thermal conductivity performance, adhesion.

As shown in FIG. 3, the mixing part 40 is provided with a level sensor 54 to measure the level of the fresh water. In addition to the water level sensor 54, the water outlet 20 of the mixing section 40 is provided with a water extraction sensor 55 to detect the temperature of the fluid evenly mixed. That is, since the temperature is sensed in a state where the fluid supplied through the outlet 20 is uniformly mixed, the accuracy of the temperature can be expected.

Here, the correction value may be calculated by sensing the temperature sensed by the water extraction sensor 55 and sensing the temperature by the water intake sensor 51. The amount of heat generated by the heater can be corrected according to the correction value.

That is, when the fluid is heated by adjusting the calorific value of the heater 200 by measuring the temperature of the water inlet sensor 51, the temperature of the heated fluid is detected by the water outlet sensor 55,

The water extraction sensor 55 calculates a correction value between the fluid temperature of the heating state and the target temperature. Accordingly, when the water extraction sensor 55 is detected to be higher than the target temperature, the water output sensor 55 lowers the amount of heat generated by the heater 200 by the correction value. If lower than the temperature is to increase the amount of heat generated by the heater 200 by the correction value.

In other words, based on the information detected from the water inlet sensor 51 and the water outlet sensor 55, the water outlet sensor 55 determines whether the fluid to be withdrawn is withdrawn at an appropriate temperature, and then calculates a correction value based on the result. By adjusting the amount of heat of the heater 200, the program for adjusting the amount of heat is mounted.

Hereinafter, the operation of the instantaneous hot water device for a washing machine according to the present invention will be described with reference to FIGS. 1 to 8.

The present invention is controlled by the microcomputer of the washing machine not shown. Therefore, when a user presses the washing button of the scrubber, an inlet device (eg, a pressure pump, a pressure reducing valve, a non-return valve, a water jet device, etc.) is operated to introduce fluid into the inlet 10.

Thereafter, the temperature of the fluid introduced into the inlet 10 is detected by the inlet sensor 51, and then electricity is supplied to the heating element 210 in the heater 200 through the lead wire 202. At this time, the microcomputer not shown adjusts the amount of heat generated by the heating element 201 according to the sensing temperature of the inlet sensor 51.

Thereafter, the fluid is sufficiently heat exchanged with the heating element 210 of the heater 200 while passing through the zigzag-shaped flow path 31 of the heat exchanger 30 shown in FIG. 6. And the heat exchanged fluid flows into the mixing part 40 in a state where the cold water layer which does not contact with the hot water layer of the part in contact with the heater 200 is laminar as shown in FIG. 4.

Next, as the fluid introduced into the mixing part 40 generates a vortex in a predetermined space, the fluid in the laminar flow state is sufficiently mixed to form a fluid having a uniform temperature.

Then, the fluid mixed at the uniform temperature is supplied to the scrubber (not shown) through the outlet. And the temperature of the fluid mixed at a uniform temperature is sensed by the water extraction sensor 55 at the water outlet 20 side.

At this time, the temperature of the fluid is constant regardless of the detection position because it is sufficiently mixed. And accurate temperature sensing is possible.

Next, after calculating the correction value by calculating the temperature detected by the water extraction sensor 55 with the target temperature, a program for correcting the amount of heat generated for the heating element 210 in the heater 200 is executed according to the calculated correction value. According to the program executed in this way, the outlet 20 may be withdrawn from the fluid at the target temperature.

In this case, in the bimetal 53, when the heating element 210 rises above a prescribed temperature, the bimetal 53 cuts off the current supplied to the heating element 210 through the lead wire 202, and cuts off the current to below the prescribed temperature. When lowered, current is supplied to the heating element 210 again.

When abnormal overheat occurs in the heating element 210 of the heater 200, the fuse 52 blocks the current supplied to the heating element 210 through the lead wire 202 to prepare for a safety accident.
