As shown in fig. 6, the water purifying apparatus provided by the embodiment of the present invention further includes a heating device 110, the balance tank 104 is provided with a first drainage port and a second drainage port, the first drainage port is communicated with the water outlet nozzle 106 of the water purifying apparatus, the second drainage port is communicated with the heating device 110, and the height of the first drainage port and the height of the second drainage port are both higher than the height of the water outlet nozzle 106.
Specifically, the heating device 110 is used to heat the water pumped into the balance tank 104 at normal temperature, so that the water purifying apparatus has a heating function. Wherein, the first drainage port is communicated with the water outlet nozzle 106 to output normal temperature water to the water outlet nozzle 106; the second water outlet is communicated with the heating device 110 for pumping normal temperature water into the heating device 110 for heating by the heating device 110 and simultaneously realizing the purpose of dry heating prevention.
The height of the first drainage port on the balance water tank 104 is set to be higher than that of the water outlet nozzle 106 of the water purifying equipment, so that the normal-temperature water in the balance water tank 104 can always flow to the water outlet nozzle 106 under the action of gravitational potential energy of the normal-temperature water, and the normal-temperature water in the balance water tank 104 can be led out from the water outlet nozzle 106 without additionally arranging a power device at the position of the water outlet nozzle 106 of the normal-temperature water of the water purifying equipment; by communicating the second water outlet on the balance water tank 104 with the heating device 110 and setting the height of the second water outlet higher than the height of the water outlet nozzle 106 of the water purifying apparatus, the water at normal temperature in the balance water tank 104 can flow to the heating device 110 and flow to the water outlet nozzle 106 of the water purifying apparatus through heating by the heating device 110, so that the heated hot water can flow to the water outlet nozzle 106 under the action of gravitational potential energy of the heated hot water without additionally arranging a power device at the position of the water outlet nozzle 106 of the hot water of the water purifying apparatus. Thus, the design and manufacturing costs of the water purification apparatus can be reduced. In addition, since the normal temperature water and the hot water share one water outlet nozzle 106, the water flow rate at the position of the water outlet nozzle 106 can be kept constant.
According to one embodiment of the invention, the bottom of the equalization tank 104 is higher than the top of the heating device 110. That is, the balance tank 104 is positioned higher than the heating means 110 in the vertical direction.
By setting the bottom of the balance water tank 104 to be higher than the bottom of the heating device 110, it is not necessary to additionally arrange a detection device in the heating device 110, and it is also not necessary to detach the heating device 110 to check whether water remains in the heating device 110 by human observation, and it is possible to ensure that water is always present in the heating device 110 only by the potential energy generated by the liquid level difference between the balance water tank 104 and the heating device 110. Further, the heating device 110 can be prevented from being burnt, the heating device 110 is prevented from being burnt out, and the service life of the water purifying equipment is ensured.
Specifically, the principle of preventing the heating device 110 from being dry-burned by the water purifying apparatus provided by the embodiment of the present invention is as follows:
by setting the bottom surface of the balance water tank 104 to be higher than the top surface of the heating device 110, the atmospheric pressure in the balance water tank 104 is equal to the atmospheric pressure in the heating device 110, so that the normal-temperature water flowing toward the heating device 110 in the balance water tank 104 always flows toward the heating device 110 by its gravitational potential energy. This ensures that at least some of the water at normal temperature will flow to the heating device 110 as long as there is water at normal temperature in the equalization tank 104. Even if a user receives hot water from the heating device 110, the normal-temperature water in the balance water tank 104 can still supplement water into the heating device 110, and the effect of preventing the heating device 110 from being dried is achieved.
In a preferred embodiment, the water purifying apparatus further comprises a buffer water tank 118 in the water tank assembly, and an air inlet 122 is disposed at the bottom of the buffer water tank 118, and the air inlet 122 is configured to communicate with the heating device 110.
Accordingly, the buffer water tank 118 is communicated with the heating device 110 through the exhaust pipe 126, and accordingly, an exhaust port communicated with the exhaust pipe 126 is provided at the top of the heating device 110. By configuring the air inlet 122 to communicate with the heating device 110, the water vapor generated in the heating device 110 can be introduced into the buffer water tank 118 without flowing out through the water outlet nozzle 106, thereby avoiding scalding of the user.
Further, an air outlet 128 is provided on the upper tank 130, and the buffer water tank 118 communicates with the outside through the air outlet 128. By arranging the air outlet 128 on the upper box body 130, the water vapor in the buffer water tank 118 after being naturally cooled can be discharged to the outside through the air outlet 128, and the user is further prevented from being scalded by the water vapor.
Still further, according to one embodiment of the present invention, the bottom surface of the surge tank 118 is not lower than the plane in which the top of the surge tank 104 is located. By setting the bottom surface of the buffer water tank 118 not to be lower than the plane on which the top of the balance water tank 104 is located, the water vapor in the buffer water tank 118 does not cause temperature interference to the normal-temperature water in the balance water tank 104, and the temperature change of the normal-temperature water in the balance water tank 104 is avoided.
The water purifying device provided by the embodiment of the invention comprises but is not limited to one of a water purifying dispenser, a water purifier, a water dispenser or a water purifier.
The working process of the water purification apparatus is explained as follows:
the water outlet nozzle 106 is normally open, and when the normal temperature water solenoid valve is turned on, the first drain port in the balance tank 104 is higher than the water outlet nozzle 106, and the balance tank 104 is communicated with the water outlet nozzle 106, so that the two are in a state of air pressure balance. Thus, the first drain opening and the nozzle 106 can be considered as an inverted U-shaped tube, and the liquid level between the first drain opening and the nozzle 106 is determined by the nozzle 106 at the lower position under the siphon principle. The normal temperature water in the balance tank 104 flows from the balance tank 104 to the water outlet nozzle 106 under the action of its gravitational potential energy.
With the pump 138 in operation, the equilibrium tank 104 is constantly replenished with water at ambient temperature from the clean water tank 102. Therefore, if water is stored in the balance tank 104 and the outlet nozzle 106 is opened, normal temperature water flows out from the outlet nozzle 106.
Meanwhile, if there is no water in the heating device 110, the water inside the balance tank 104 will directly flow into the heating device 110 through the second water outlet under the action of its gravitational potential energy because of the height difference between the balance tank 104 and the heating device 110. At this time, water storage in the heating device 110 is started. When the highest water level in the heating device 110 and the lowest water level in the balance tank 104 are level with each other, the water inside the balance tank 104 does not flow into the heating device 110 any more. This ensures that water remains in heating device 110 at all times, and further, prevents dry heating of heating device 110.
When the hot water solenoid valve is turned on, the second water outlet of the balance water tank 104 is higher than the water outlet nozzle 106, and the balance water tank 104 and the water outlet nozzle 106 are communicated with each other, so that the two are in a state of air pressure balance. Thus, the second outlet, the heating device 110 and the nozzle 106 can be considered as an inverted U-shaped tube, and the liquid level between the second outlet and the nozzle 106 is determined by the nozzle 106 in the lower position under the siphon principle. The normal temperature water in the balance water tank 104 flows from the balance water tank 104 into the heating device 110 under the action of its gravitational potential energy, and then flows to the water outlet nozzle 106 after being heated by the heating device 110.
At the same time, the water level in the heating device 110 drops, and the water pump 138 is in operation, so that the normal temperature water in the clean water tank 102 is continuously replenished into the balance water tank 104, and the water in the balance water tank 104 still flows to the heating device 110. Even if no water is stored in the balance water tank 104, due to the position relation between the balance water tank and the balance water tank, the lowest water level in the heating device 110 can be at least ensured to be flush with the bottom surface of the balance water tank 104, and then the dry burning prevention of the heating device 110 is realized.
Meanwhile, because there is water inside the balance water tank 104, the height of the first drainage port is higher than that of the water outlet nozzle 106, and the balance water tank 104 and the water outlet nozzle 106 are communicated with each other, the two are in a state of air pressure balance. Thus, there is always a water spot in the line from the balance tank 104 to the outlet nozzle 106.
From the above working states, the water purifying apparatus can realize the functions of discharging water and preventing the heating device 110 from being burned dry at the same time by using the gravitational potential energy of the water. Therefore, the water purifying device provided by the embodiment of the invention is a complete and inseparable whole.
