[0003] Preheating water dispensers are widely used in homes and offices due to their ease of use. They rapidly heat water to meet the demand for instant hot and room temperature drinking water. One publicly disclosed preheating instant water dispenser includes a water tank, a water circuit board, and a top-mounted faucet assembly. The faucet assembly has an upper water tank cover, a middle water inlet, and an end outlet. A drip tray is located directly below the outlet. A heating and circulation mechanism is located on the left side of the water tank.

The water circuit board is a single piece without silicone joints, resulting in a complex structure and high development costs. Furthermore, due to its structure, the water circuit board results in an excessively long water path, creating a time interval between the water output time and the initial command transmission.

[0039] In one possible implementation, the hot water inlet 25 of the diversion valve 7 is connected to the outlet 28 of the diversion fixed pipe 6, the inlet 29 of the diversion fixed pipe 6 is connected to the outlet 30 of the heating element 5, and the inlet 31 of the heating element 5 is connected to the outlet of the water pump.

[0040] In one possible implementation, the water circuit board body 3 is connected to the water tank body 4, forming a raised water inlet 35 and a water tank vent 34, and then a water pump is connected to the water tank outlet 32 ​​to form an output outlet.

[0041] In one possible implementation, a level switch 37 is provided at the center of the water circuit board body 3 for monitoring the water level.

[0042] In one possible implementation, the top surface 36 of the water circuit board body 3 forms a water inlet for connecting to an external water source.

[0043] In one possible implementation, the side of the water circuit board body 3 is formed with a normal temperature water drain outlet 20, a hot water drain outlet 21 and an exhaust outlet 22, a hot water circulation inlet 24, and a liquid level switch 37.

[0044] In one possible implementation, the water tank body assembly consists of a water tank body 4, a water circuit board body 3, a water tank drain outlet 33, and a water tank outlet 32. The water circuit board body 3 connects to the water tank 4 and forms a water inlet 35 therein, which is set at the same height as the water tank vent 34, and then connects to a water pump through the water tank outlet 32 ​​to form an output outlet.

[0045] In one possible implementation, the preheating water circulation channel is formed by connecting the water tank body 4 and the water circuit board body 3 to form a water inlet 35 and an exhaust port 34. The hot water circulation inlet 24 and the water tank outlet 32 ​​are connected to the diversion inlet 25 to form a circulating water channel.

[0046] In one possible implementation, the water tank body 4 and the water circuit board cover 3 form an exhaust port 22, which is located near the hot water outlet 21; the diameter of the ventilation channel is the same as the diameter of the water flow channel, which is smaller than the diameter of the normal temperature outlet; and the water circuit board adopts an integrated design structure without silicone tubes.

[0047] In one possible implementation, the water circuit board body 3 circulates water, vents water and air, and supplies water to the water tank body 4. The top surface 36 of the water circuit board body 3 has a water inlet that can be directly connected to a faucet, etc. The side of the water circuit board body 3 has an inlet 11 and an outlet 12 controlled by a normal temperature water solenoid valve 1, and a water tank inlet 15 and an outlet 16 controlled by a water tank solenoid valve 2. The other side has a preheating circulation inlet 24, a hot water outlet 23, a normal temperature water outlet 20, a hot water outlet 21, an exhaust outlet 22, and a level switch 37, forming a water circulation, exhaust, and water inlet / outlet separation system.

[0048] In one possible implementation, the vent 34 is used to promptly expel air from the water tank body 4. The inlet 35 is used for water intake and replenishment. The water tank body 4 stores water supplied by the water circuit board 3 and can circulate water according to software settings. The water tank body assembly consists of the water tank 4, water circuit board 3, diversion valve 7, diversion fixing pipe 6, heating element 5, and water pump. The water tank body forms a drain outlet 33 for drainage, and the outlet 32 ​​is used to connect the water pump to the heating element 5, connect the diversion pipe 6, connect the diversion valve 7 to the water circuit board 3, and then install a sealing silicone ring on the water circuit board and fix it with screws to form a circulating heat preservation and preheating system.

[0049] In one possible implementation, the water pipe and the ventilation pipe are made of one-piece molded food-grade high-temperature resistant PP material.

[0050] In one possible implementation, taking the application of an automatic water supply circulation preheating water circuit board on a water dispenser as an example, the water circuit board body 3 is installed and fixed above the opening of the water tank body 4, and then the entire assembly is installed and fixed on the right side of the whole machine, so that there is a certain height difference between the water circuit board body 3 and the water tank body 4.

[0051] Working principle:

[0052] After the water pipe 36 is connected to the water flow, under the force of water pressure, and controlled by the solenoid valve 1, the room temperature water flows out from the large flow outlet 20 through the inlet 8. Controlled by the solenoid valve 2 and influenced by gravity, the water flows into the water tank 4 through the flow channel. The water level is controlled by the ultrasonic level switch 37. Once the specified water level is reached, the solenoid valve 2 closes the water flow. Upon system recognition, the circulating heating preheating is initiated. The water is drawn from the outlet 32 ​​into the heating device 5 by the suction of the water pump, then flows into the water tank 4 through the diversion valve 7 via a fixed pipe, forming a circulating preheating cycle. Once the predetermined temperature is reached, the water pump and heating element stop working. With the water tank 4 sealed, the circulating heating steam is discharged through the exhaust port 34 under atmospheric pressure. When hot water is produced after preheating or before preheating, the hot water is discharged from the outlet 26 of the reversing valve 7 to the faucet 8 for use.

[0053] It can be seen that the water circuit board utilizes atmospheric pressure and gravity to achieve automatic water supply without a water pump, and the water supply volume is consistent each time, thus achieving precise water supply.

[0054] Furthermore, when water at a temperature higher than that of the tank is dispensed after preheating, the former dispenses more water in a shorter time compared to when no preheating is required. Because the water supply tank in this application eliminates the need for silicone tubing and uses a one-piece molded food-grade high-temperature resistant material, it not only reduces the likelihood of repairs but also saves on manufacturing costs.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
