[0002] The existing instant hot water dispenser includes an integrated water tank, a pipe heater and a circuit board. The integrated water tank is provided with a water inlet and a water outlet. The water outlet is arranged below the middle of the integrated water tank. The pipe heater is located below the water outlet and connected to the water outlet.

[0003] The integrated water tank comprises a balanced water level area and a hot water area. The balanced water level area needs to be installed with a water level monitoring device, which is used to monitor the water level of the balanced water tank to facilitate water replenishment operations.

[0004] However, the existing instant hot water dispenser has a single integrated water tank structure, which results in the instant hot water dispenser being unable to adjust the outlet water temperature and only being able to outlet hot water, with a single function. Summary of the invention

[0005] The object of the present invention is to provide a multifunctional instant heating machine capable of switching between hot water and warm water.

[0006] The object of the present invention is achieved in that:

[0007] A multifunctional instant heating machine comprises an integrated water tank and an instant heating pipe heater, wherein the integrated water tank comprises a water storage area and a hot water area, wherein the water storage area is provided with a water storage inlet and a water storage outlet, wherein the hot water area is provided with a cold water inlet, a hot water inlet and a water outlet, wherein the cold water inlet is connected to the water storage area, wherein the instant heating pipe heater is connected between the water storage outlet and the hot water inlet, and further comprises a regulating valve, wherein a water conducting cavity is provided in the regulating valve, wherein a high water level port, a first low water level port and a second low water level port communicating with the water conducting cavity are respectively opened on the regulating valve, wherein the regulating valve extends into the hot water area, and the water conducting cavity is communicated with the hot water inlet, wherein the regulating valve is rotated to realize the switching of the following states:

[0008] Hot water state: the first low water level port of the regulating valve is closed, and the high water level port is connected to the water outlet;

[0009] Warm water state: the first low water level port is connected to the water storage area, and the second low water level port is connected to the water outlet.

[0010] The user rotates the regulating valve, and when the first low water level port of the regulating valve is closed and the high water level port is connected to the water outlet, the water in the water storage area enters the instant hot pipe heater along the water storage outlet for heating, and the water in the instant hot pipe heater boils and splashes out of the hot water inlet to form hot water, and the hot water is discharged to the water outlet along the water guide cavity and the high water level port. The user rotates the regulating valve, and when the first low water level port of the regulating valve is connected to the cold water inlet and the second low water level port is connected to the water outlet, part of the water in the water storage area enters the instant hot pipe heater along the water storage outlet for heating, and the water in the instant hot pipe heater boils and splashes out of the hot water inlet to form hot water, and the hot water enters the water guide cavity, and another part of the water in the water storage area enters the water guide cavity along the cold water inlet, and the hot water and cold water are mixed in the water guide cavity to form warm water, and the warm water is discharged to the water outlet along the second low water level port. Therefore, the user can switch between hot water and warm water by rotating the regulating valve, and the operation is very simple.

[0011] The purpose of the present invention can also be solved by the following technical measures:

[0012] Furthermore, the regulating valve rotates to change the size of the conduction angle between the second low water level port and the water outlet. By changing the size of the conduction angle between the second low water level port and the water outlet, the water output of the warm water is adjusted, and the operation is simple.

[0013] Furthermore, the regulating valve includes a hollow sleeve with an opening at the bottom and a sealed top, the high water level port, the first low water level port and the second low water level port are respectively arranged on the outer side wall of the hollow sleeve, the inner cavity of the hollow sleeve constitutes a water guiding cavity, the hollow sleeve is inserted into the hot water area from top to bottom, and the bottom opening edge of the hollow sleeve is rotated against the periphery of the hot water inlet so that the hot water inlet is located in the hollow sleeve.

[0014] Furthermore, the integrated water tank has a water storage cavity, a boss in the water storage cavity, a hot water area surrounded by an outer wall is arranged on the boss, the outer wall is provided with the cold water inlet and outlet, and the hot water inlet is arranged on the boss in the outer wall.

[0015] Furthermore, an inner wall is provided on the boss between the outer wall and the hot water inlet, and two notches are respectively provided on the inner wall corresponding to the cold water inlet and the water outlet of the outer wall. A rotation gap exists between the inner wall and the outer wall, and the lower part of the hollow sleeve is inserted into the rotation gap, and the bottom opening edge of the hollow sleeve rotates against the edge of the hot water inlet.

[0016] Furthermore, it also includes a knob, which is seated on the top of the integrated water tank. The regulating valve is provided with a rotating shaft, which extends out of the top of the integrated water tank to connect the knob, and the knob drives the regulating valve to rotate.

[0017] Furthermore, a limiting column is provided on the top of the regulating valve, and a first limiting block and a second limiting block are provided on the top inner wall of the integrated water tank. The first limiting block and the second limiting block form a limiting area. The limiting column extends into the limiting area. The limiting area limits the sliding distance of the limiting column, limits the rotation angle of the regulating valve, and thus limits the rotation angle of the knob.

[0018] A limiting column is provided on the top of the regulating valve, and the limiting column extends into the limiting area. The limiting area limits the sliding distance of the limiting column, limits the rotation angle of the regulating valve, and thus limits the rotation angle of the knob, thereby limiting the user to only switch between the closed state, hot water state and warm water state by rotating the knob, avoiding user misoperation and ensuring smooth switching between the closed state, hot water state and warm water state.

[0019] Furthermore, the first limit block and the second limit block form an arc-shaped limit area, and when the limit column slides from the first limit block to the second limit block, the regulating valve rotates 180 degrees.

[0020] Furthermore, a micro switch is included, which is electrically connected to the instant pipe heater, and the push rod of the micro switch faces the knob, and the knob is provided with a pressing flange. When the knob rotates, when the push rod abuts against the pressing flange, the micro switch starts / turns off the instant pipe heater, and when the push rod moves away from the pressing flange, the micro switch turns off / starts the instant pipe heater.

[0021] By providing a micro switch, when switching to the hot water state or the warm water state, the pressing flange of the knob just abuts against the push rod, so that the micro switch starts the instant pipe heater. When switching to the off state, the pressing flange of the knob moves away from the push rod, so that the micro switch turns off the instant pipe heater, which greatly improves the safety of using the multifunctional instant heating machine.

[0022] Furthermore, it also includes a spring and a ball, the bottom of the knob / the top of the integrated water tank are separated by a groove, the top of the integrated water tank / the bottom of the knob are separated by a spring accommodating cavity, the spring is placed in the spring accommodating cavity, the ball sits on the spring, one end of the ball rests on the spring, and the other end of the ball rests in the corresponding groove, and the spring constitutes a resetting mechanism for the ball.

[0023] When the knob is rotated, the ball enters or leaves the groove at the bottom of the knob to generate vibration, and the user has a better feel when rotating the knob. In addition, a spring accommodating cavity is opened on the top of the integrated water tank corresponding to the closed state, hot water state and warm water state. The spring is placed in the spring accommodating cavity, and the other end of the spring is against the ball. Therefore, when the user rotates to the closed state, hot water state and warm water state, corresponding vibrations can be generated, which is convenient for the user to know the state switching, greatly improving the practicality of the multi-functional instant heating machine.

[0024] The beneficial effects of the present invention are as follows:

[0025] According to the present invention, the user rotates the regulating valve, and when the first low water level port of the regulating valve is closed and the high water level port is connected to the water outlet, the water in the water storage area enters the instant hot pipe heater along the water storage outlet for heating, the water in the instant hot pipe heater boils and splashes out of the hot water inlet to form hot water, and the hot water is discharged toward the water outlet along the water guide cavity and the high water level port. The user rotates the regulating valve, and when the first low water level port of the regulating valve is connected to the cold water inlet and the second low water level port is connected to the water outlet, a part of the water in the water storage area enters the instant hot pipe heater along the water storage outlet for heating, the water in the instant hot pipe heater boils and splashes out of the hot water inlet to form hot water, and the hot water enters the water guide cavity, and another part of the water in the water storage area enters the water guide cavity along the cold water inlet, the hot water and the cold water are mixed in the water guide cavity to form warm water, and the warm water is discharged toward the water outlet along the second low water level port. Therefore, the user can switch between hot water and warm water by rotating the regulating valve, and the operation is very simple.

[0026] The present invention is provided with a micro switch. When switched to the hot water state or the warm water state, the pressing flange of the knob just abuts against the push rod, so that the micro switch starts the instant pipe heater. When switched to the off state, the pressing flange of the knob is away from the push rod, so that the micro switch turns off the instant pipe heater, which greatly improves the safety of the multifunctional instant heating machine.

[0027] According to the present invention, when the knob is rotated, the ball enters or leaves the groove at the bottom of the knob to generate vibration, so that the user has a better hand feel when rotating the knob. In addition, a spring accommodating cavity is opened on the top of the integrated water tank corresponding to the closed state, hot water state and warm water state.

Two notches 123 are respectively provided on the inner wall 122 at the positions corresponding to the cold water inlet 15 and the water outlet 16 of the outer wall 121. A rotation gap 124 exists between the inner wall 122 and the outer wall 121.

[0057] The water storage cavity 11 outside the outer wall 121 forms a water storage area 17 . The base 1 is provided with a water storage inlet 171 and a water storage outlet 172 connected to the water storage area 17 . The cold water inlet 15 is connected to the water storage area 17 .

[0058] The upper cover 2 is fixed to the top opening of the base 1 , and the bottom wall of the upper cover 2 is provided with a first limit block 21 and a second limit block 22 , which enclose a limit area 23 , and the limit area 23 is an arc-shaped limit area 23 .

[0059] The top of the return pipe 3 is provided with an open opening 31, and the upper outer wall of the return pipe 3 near the open opening 31 is provided with a small groove 32, the small groove 32 is connected to the open opening 31, and the open opening 31 and the small groove 32 together constitute a return opening 33, the lowest end of the return opening 33 is the bottom edge of the small groove 32, and the highest end is the edge of the open opening 31.

[0060] The reflux pipe 3 passes through the bottom of the water storage area 17 from bottom to top and extends into the water storage area 17, and the lowest end of the reflux port 33 is lower than the water storage inlet 171, and the lowest end of the water outlet 16 is located between the lowest end and the highest end of the reflux port 33. The bottom of the reflux pipe 3 has an open opening to form a bottom port 34.

[0061] The water box 4 is located below the integrated water tank, the inlet of the water pump 10 is connected to the water inlet pipeline 101, the outlet of the water pump 10, the water storage inlet 171 and the bottom port 34 of the return pipe 3 are respectively connected to the water box 4, the inlet of the instant hot pipe heater 8 is connected to the water storage outlet 172, and the outlet of the instant hot pipe heater 8 is connected to the hot water inlet 14.

[0062] The regulating valve 5 includes a hollow sleeve with an opening at the bottom and a sealed top. The inner cavity of the hollow sleeve constitutes a water guide cavity 51. The outer wall of the hollow sleeve is provided with a high water level port 52, a first low water level port 53 and a second low water level port 54. The hollow sleeve is inserted into the rotating gap 124 from top to bottom, and the bottom opening edge of the hollow sleeve rotates against the edge of the hot water inlet 14 so that the hot water inlet 14 is located in the hollow sleeve, and the water outlet 9 is connected to the water outlet 16.

[0063] The top of the upper cover 2 is separated by grooves 24, the knob 6 is provided with a pressing flange 61, and the bottom of the knob 6 is separated by spring accommodating chambers 62. The knob 6 sits on the top of the upper cover 2, and the spring 63 is placed in the spring accommodating chamber 62.

The spring 63 constitutes a reset mechanism for the ball 64.

[0064] The regulating valve 5 is provided with a rotating shaft 55 and a limiting column 56. The rotating shaft 55 extends out of the top of the upper cover 2 to connect with the knob 6. The knob 6 drives the regulating valve 5 to rotate. At the same time, the limiting column 56 extends into the limiting area 23. The limiting area 23 limits the sliding distance of the limiting column 56. When the limiting column 56 slides from the first limiting block 21 to the second limiting block 22, the regulating valve 5 rotates 180 degrees, so that the limiting area 23 limits the rotation angle of the regulating valve 5, thereby limiting the rotation angle of the knob 6.

[0065] The micro switch 7 is electrically connected to the instant pipe heater 8, and the push rod 71 of the micro switch 7 is directed toward the knob 6. The knob 6 rotates. When the push rod 71 abuts against the pressing flange 61, the micro switch 7 starts the instant pipe heater 8. When the push rod 71 moves away from the pressing flange 61, the micro switch 7 turns off the instant pipe heater 8.

[0066] The regulating valve 5 rotates to change the size of the conduction angle between the second low water level port 54 and the water outlet 16 or between the high water level port 52 and the water outlet 16 .

[0067] Working principle:

[0068] Closed state:

[0069] When the multifunctional instant heating machine is in the off state, the limit column 56 is at the center position of the limit area 23, and at the same time, the flange 61 is pressed away from the push rod 71 of the micro switch 7, and the micro switch 7 turns off the instant pipe heater 8. At this time, the outer wall of the regulating valve 5 closes the water outlet 16, resulting in the water outlet 16 being unable to drain.

[0070] Hot water status with maximum water output:

[0071] The user rotates the knob 6 counterclockwise, and when the limit column 56 abuts against the first limit block 21 (the regulating valve 5 rotates 0°), and the flange 61 is pressed against the push rod 71, the micro switch 7 starts the instant hot pipe heater 8, and the outer wall 121 closes the first low water level port 53, and the high water level port 52 is connected to the water outlet 16. The water in the water storage area 17 enters the instant hot pipe heater 8 along the water storage outlet 172 for heating, and the water in the instant hot pipe heater 8 boils and sprays out of the hot water inlet 14 to form hot water, and the hot water is discharged to the water outlet 9 along the water guide cavity 51, the high water level port 52, and the water outlet 16.

[0072] Adjust the hot water output:

[0073] The user can adjust the conduction angle between the high water level port 52 and the water outlet 16 by rotating the knob 6 within the range of 0°-90°, thereby adjusting the output amount of hot water.

[0074] Warm water state with maximum water output:

[0075] The user rotates the knob 6 clockwise, and when the limit column 56 abuts against the second limit block (the regulating valve 5 rotates 180°), and the flange 61 is pressed against the push rod 71, the micro switch 7 starts the instant hot pipe heater 8, and the first low water level port 53 is connected to the cold water inlet 15, and the second low water level port 54 is connected to the water outlet 16. The water in the water storage area 17 enters the instant hot pipe heater 8 along the water storage outlet 172 for heating, and the water in the instant hot pipe heater 8 boils and sprays out of the hot water inlet 14 to form hot water, and the hot water enters the water guide cavity 51. At the same time, the water in the water storage area 17 enters the water guide cavity 51 along the cold water inlet 15 and the first low water level port 53, and the cold water and the hot water are mixed in the water guide cavity 51 to form warm water, and the warm water is discharged to the water outlet 9 along the second low water level port 54 and the water outlet 16.

[0076] Adjust the warm water output:

[0077] The user can rotate the knob 6 within the range of 90°-180° to adjust the conduction angle between the second low water level port 54 and the water outlet 16, thereby adjusting the water output of the warm water.

[0078] Water outlet 9 anti-drip:

[0079] When the multifunctional instant heating machine is in the off state, water in the water storage area 17 which is higher than the open opening 31 at the top of the return pipe 3 enters the return pipe 3 along the open opening 31 and is discharged into the water box 4. At the same time, water in the water storage area 17 which is lower than the open opening 31 at the top of the return pipe 3 enters the return pipe 3 along the small groove 32 and is discharged into the water box 4. Therefore, water in the water storage area 17 which is higher than the open opening 31 at the top of the return pipe 3 and water in the water storage area 17 which is lower than the open opening 31 at the top of the return pipe 3 enters the return pipe 3 at the same time and is discharged into the water box 4, which greatly accelerates the water reflux in the water storage area 17.

[0080] Moreover, the open mouth 31 and the small groove 32 together constitute a return port 33, the lowest end of the return port 33 is the bottom edge of the small groove 32, and the highest end is the edge of the open mouth 31, and the lowest end level of the water outlet 16 is located between the lowest end and the highest end of the return port 33. Therefore, when the multifunctional instant heating machine is in a closed state, the water level of the water storage area 17 is lower than the lowest end of the return port 33, and the lowest end level of the water outlet 16 is located between the lowest end and the highest end of the return port 33. Therefore, the water level of the water storage area 17 is lower than the lowest end level of the water outlet 16, and the water in the water storage area 17 cannot enter the water outlet 16, so the water outlet 9 will not drip.
