FIG. 1 is a view showing a conventional circulation pump separately. FIG.
2 to 4 are views showing the inside of the hot water supply apparatus of the present invention.
5 to 8 are views showing the inside of the hot water supply apparatus according to another embodiment of the present invention.

Hereinafter, the configuration of the present invention will be described in detail with reference to embodiments of the present invention shown in the drawings.

2 to 4 are views showing the inside of the hot water supply apparatus of the present invention. Referring to FIG. 2, the hot water supply device 100 has a path through which water flows in from the outside and flows out through the inside of the hot water supply device 100, and includes a water receiving part 400 containing water, And a heating unit 110 for heating the substrate.

The tube 300 is made of a resilient material such as synthetic resin or rubber. The tube 300 has a U-shape inside, and the circulation operation part 200 is located in the space between the tubes.

The circulation operation unit 200 functions to press the tube 300 and push the hot water therein in one direction. The circulation operation part 200 includes a rotation motor 210 and a rotation support part 220 coupled to a shaft connected to the rotation motor 210. A pressing roller 230 is provided at an extended end of the rotation support part 220. The pressing roller 230 presses and presses a part of the tube 300 to deform the tube 300. When the rotation supporting part 220 is rotated in one direction by the rotation motor 210, , And pushes the hot water inside it forward.

At this time, the tube is arranged in a state in which the pressing curved portion 310 is formed around the rotational axis of the rotating motor 210 as an arc between the portions indicated by dotted lines of A and B, and the tube is spaced apart by a certain distance. The pressing roller 230 pushes the inner portion of the tube 300 in the pressing portion 310 of the tube 300 and pushes the inner portion of the tube 300 in the direction opposite to the clockwise rotation as shown by an arrow. The pressing roller 230 is pushed out while pushing the pressing roller 230 while pressing the pressing roller 230. When the pressing roller 230 is also engaged with the pressing roller 230, The pressure with the tube 300 is released, and the tube is continuously pivoted while the pressure in the tube B is continuously increased.

In this manner, the circulation operation unit 200 of the complex configuration is neither exposed to water nor contact with water, and noise due to contact with water is not generated. The hot water in the tube 300 circulates smoothly as the pressure roller 230 continuously presses the tube 300 and pushes it to one side.

3, a protruding pumping part 320 is protruded from the tube 300 and a known one-way valve 500 is installed at one side of the tube 300. The protruding pumping portion 320 protrudes outwardly from the other portion of the tube 300 and is an enlarged cross-sectional area and volume. The protruding pumping portion 320 is a portion that maintains elasticity, It works.

As described above, when the pressure roller 230 rotates, the pressure roller 230 comes to the position of the protruding pumping portion 320 and presses the portion. At this time, water is supplied to the side where the one-way valve 500 is installed The water is pushed in the direction opposite to the clockwise rotation in the drawing. When the pressure roller 230 moves away from the protruding pumping portion 320, the portion of the pressure roller 230 is inflated again, and the hot water passes through the unidirectional valve 500 to allow the water to flow into the portion due to a pressure change. The unidirectional valve 500 may be selectively coupled to either of the tubes 300, and is preferably connected to a portion of the tube 400 that is discharged from the water receiving portion 400.

Referring to FIG. 4, the circulating operation unit 600 may be pressed by the solenoid 610, not by the motor rotating method, to the protruding pumping unit 320 in the same manner. The input / output support portion 620 is drawn in and out according to the operation of the solenoid 610 and the pressure roller 630 at the end portion is vertically moved so that the protruding pumping portion 320 is pushed and released. Operation. Out support portion 620 may directly contact the protruding pumping portion 320 without the pressure roller 630. [

5 to 7 are views showing the inside of a hot water supply apparatus according to another embodiment of the present invention. Referring to FIG. 5, the volume of the water receiving part 400 itself is changed to perform a pumping operation.

When the volume of the water receiving part 400 is increased, the inside of the tube 300 is brought into a low pressure state, and water in the tube 300 flows into the water receiving part 400, The water is drawn into the tube 300 through the unidirectional valve 500 of the tube 300 when the volume is reduced.

For this, a constriction expanding part 410 is provided in an open state at one side of the case 440 of the water receiving part 400, and a connection part 420 is formed between the fixing part 430 and the fixing part 430. The shrinking and expanding part 410 and the connecting part 420 are preferably made of materials such as synthetic resin and rubber that can be expanded and contracted and the connecting part 420 has a wrinkle shape that can be stretched and reduced while maintaining elasticity. The fixing portion 430 is a portion fixed to the case 440.

The circulation operation portion 600 is for increasing or decreasing the internal volume of the water receiving portion 400 while changing the displacement of the contraction expanding portion 410. The solenoid 610 draws out the incoming and outgoing support portion 620 to expand the contraction expanding portion 410 may be pushed inward or pulled in the opposite direction to pull out the contraction bulging portion 410 outward. The input / output support portion 620 may be coupled to the expansion / contraction portion 410 through the coupling portion 640.

Referring to FIGS. 6 and 7, a blocking unit 450 is provided to divide the space in the water receiving unit 400, and a blocking inlet 452 is formed in the blocking unit 450. A portion communicating with the inlet port 442 may be divided into a storage space 460 and a portion communicating with the outlet port 448 may be divided into a compression space 470 and a blocking inlet port 452 of the blocking portion 450 A unidirectional shutoff valve 454 is provided to allow water flow from the storage space 460 to the compression space 470 while blocking the flow in the opposite direction.

In the same operation, when the input / output portion 620 pulls the expansion / contraction portion 410 to increase the volume of the compression space 470, the water in the storage space 460 flows through the uni-directional shutoff valve 454 into the compression space 470 ).

Conversely, if the volume of the compression space 470 is reduced by pushing the contraction bulging portion 410, water is not discharged toward the blocking inlet 452 and flows toward the outlet 448 through the unidirectional valve 500 to the outside Water is drained. Reference numeral 444 denotes a water replenishment port.

Referring to Fig. 8, an embodiment in which the circulation operating portion is constituted by a cam method is described. The cam portion includes a cam 700 and an eccentric rotation axis 710. The portion of the cam 700 protruding from the rotation axis 710 is relatively pressed toward the expansion / contraction portion 410 while the cam 700 is rotated. Therefore, during the rotation of, for example, 240 degrees during one rotation, the contraction expanding portion 410 is pushed inwardly to the inside, and the original restoring operation is performed again during 120 rotations. The elastic member 720 such as a spring is provided on the inner side of the elastic member 720 so that the elastic member 720 can be more rapidly extended to the contraction and expansion portion 410 It is preferable to expand it. The elastic member 720 is preferably supported on the inner side by the blocking portion 450 as shown in the figure, and may be supported by various internal components or wall surfaces in the case where the blocking portion 450 is not provided.

When the cam 700 continuously rotates, friction is regularly generated in the contraction expanding portion 410, so that wear and noise are inevitably generated. It is preferable to further include a metal member 412 having less friction and noise, such as an oilless metal plate for preventing this. Or the expansion / contraction portion 410 may be formed of such a metal plate. As the oilless metal plate is provided, wear and noise caused by friction due to the contact of the cam 700 are reduced and the surface is prevented from being lost.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
