DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) Referring to FIG. 1 through FIG. 5, the present invention discloses an instant hot water dispenser system, comprising a main body 10, a first heating unit 30, a second heating unit 40, a processing unit 50, a plurality of temperature sensor 60, and a faucet 90.

(9) The main body 10 has a water flow control valve seat 11, a water inlet 12, and a water outlet 13. The water flow control valve seat 11 is provided with a first flow control valve 111 and a second flow control valve 112. One end of the water inlet 12 is connected to a tap water pipeline through a water pipeline, and another end of the water inlet 12 is connected to a chamber 113 of the water flow control valve seat 11. The chamber 113 communicates with the first flow control valve 111 and the second flow control valve 112. The second flow control valve 112 communicates with a first water inlet 21 of a water collection device 20. The water outlet 13 communicates with the faucet 90 through the water pipeline. A water filtering device 70 is provided between the water inlet 12 of the main body 10 and the tap water pipeline.

(10) The faucet 90 is provided with a first pull member 91, a second pull member 92, and a water outlet pipe 93. The first pull member 92 is configured to control the water supply sent from the tap water pipeline to the water outlet pipe 93. The second pull member 92 is configured to control the water supply sent from the water outlet 13 to the water outlet pipe 93.

(11) The first heating unit 30 has a first water storage space 31 and a heater. One side of the first water storage space 31 communicates with the first flow control valve 111, and another side of the first water storage space 31 communicates with the second water inlet 22 of the water collection device 20. The heater is configured to preheat the water supply in the first water storage space 31 to a predetermined temperature (the preset value is 85° C.).

(12) The second heating unit 40 has a circulating water path 41 and an instantaneous heater. One side of the circulating water path 41 communicates with a third water outlet 23 of the water collection device 20, and another other side of the circulating water path 41 communicates with the water outlet 13 of the main body 10. The instantaneous heater is configured to instantaneously heat the water supply in the circulating water path 41 to a predetermined temperature.

(13) The first heating unit 30 and the second heating unit 40 further include a plurality of temperature protection switches 80. If the first heating unit 30 or the second heating unit 40 is abnormal and the water temperature exceeds a preset value (such as a temperature above 110° C.), the processing unit 50 immediately command the first heating unit 30 or the second heating unit 40 to stop heating.

(14) The processing unit 50 is electrically connected to a control interface 51 and an external power source 52. The processing unit 50 is further electrically connected to the water flow control valve seat 11, the first heating unit 30 and the second heating unit 40. The control interface 51 is provided with a water-dispensing button, a temperature button, a number button, a temperature display, a water volume display, and a status display of the water filtering device 70.

(15) The plurality of temperature sensors 60 are respectively disposed on the water flow control valve seat 11, the first heating unit 30, the third water outlet 23 of the water collection device 20 and the water outlet 13 of the main body 10 for sensing the temperatures of the water supplies and sending a signal of the temperatures of the water supplies to the processing unit 50.

(16) Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

(17) Referring to FIG. 3 and FIG. 8, when the user wants to drink drinking water (40° C.), first, the user presses a spring rod 9211 on a safety switch 921 to slightly rotate the second puller member 92 to a predetermined position and touches a micro switch 922 to start the processing unit 50. At this time, the user elects and presses the temperature button (40° C.) on the control interface 51. When the processing unit 50 receives the water-dispensing temperature signal from the control interface 51 and determines that the water-dispensing temperature signal is 40° C., the second flow control valve 112 is opened, and the water supply in the chamber 113 is sent to the water collection device 20. If the temperature sensor 60 on the water collection device 20 detects that the temperature is less than 40° C., the water supply is sent to the circulating water path 41 in the second heating unit 40 for heating instantaneously. Finally, the water supply flows from the water outlet 13 to the water outlet pipe 93 of the faucet 90 through the water outlet pipe, so as to supply drinking water (40° C.) immediately.

(18) When the user wants to drink drinking water (60° C.), first, the user presses the spring rod 9211 on the safety switch 921 to slightly rotate the second puller member 92 to a predetermined position and touches the micro switch 922 to start the processing unit 50. At this time, the user elects and presses the temperature button (60° C.) on the control interface 51. When the processing unit 50 receives the water-dispensing temperature signal from the control interface 51 and determines that the water-dispensing temperature signal is 60° C., the second flow control valve 112 and the second water inlet 22 of the water collection device 20 are opened to mix the water supply in the chamber 113 and the water supply in the first water storage space 31 through the water collection device 20 to be at a temperature of 60° C. Finally, the water supply flows from the water outlet 13 to the water outlet pipe 93 of the faucet 90 through the water outlet pipe, so as to supply drinking water (40° C.) immediately.

(19) When the user wants to drink drinking water (95° C.), first, the user presses the spring rod 9211 on the safety switch 921 to slightly rotate the second puller member 92 to a predetermined position and touches the micro switch 922 to start the processing unit 50. At this time, the user elects and presses the temperature button (95° C.) on the control interface 51. When the processing unit 50 receives the water-dispensing temperature signal from the control interface 51 and determines that the water-dispensing temperature signal is 95° C., the second water inlet 22 of the water collection device 20 is opened, and the water supply in the first water storage space 31 is sent to the circulating water path 41 of the second heating unit 40 via the water collection device 20 for heating. When the temperature of the water supply reaches 95° C., the water supply flows from the water outlet 13 to the water outlet pipe 93 of the faucet 90 via the water outlet pipe, so as to supply drinking water (95° C.) immediately.

(20) The instant hot water dispenser system of the present invention has the following advantages:

(21) 1. The water supply with a medium-high temperature in the first water storage space 31 is sent to the circulating water path 41 of the second heating unit 40 for heating instantaneously. The water supply can be effectively heated to a specified high temperature in a short time.

(22) 2. Since the water supply in the first water storage space 31 is maintained at a medium-high temperature at any time, it can be continuously replenished to the circulating water path 41, and hot water above 95° C. is not easily consumed.

(23) Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
