Referring to fig. 1 to 6, the water purifying apparatus includes a balance tank 104 and a heating device 110, the balance tank 104 is provided with at least two water outlets, one of the water outlets is communicated with the heating device 110, and the bottom of the balance tank 104 is higher than the bottom of the heating device 110.

The purpose of setting up like this is in order to prevent that heating device 110 from appearing the condition of dry combustion method, and then can avoid heating device 110's damage, has prolonged water purification unit's life.

The principle of preventing the heating device 110 from being dry-burned is as follows:

by setting the bottom of the balance water tank 104 to be higher than the bottom 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.

Of course, the bottom of the balance tank 104 may be set higher than the top of the heating device 110 to achieve the above-described function.

In this embodiment, the at least two water outlets on the balance tank 104 include a first water outlet 112 and a second water outlet 116, the first water outlet 112 is communicated with the water outlet 106 of the water purifying device, the height of the first water outlet 112 and the height of the second water outlet 116 are both higher than the height of the water outlet 106, and the second water outlet 116 is communicated with the heating device 110.

According to the water purifying device provided by the embodiment of the invention, the height of the first drainage port 112 on the balance water tank 104 is set to be higher than that of the water outlet nozzle 106 of the water purifying device, 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 self gravitational potential energy, 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 device; by connecting the second water outlet 116 of the balance water tank 104 with the heating device 110 and setting the height of the second water outlet 116 to be 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 the heating of 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.

Specifically, the balance tank 104 of the embodiment of the present invention is used to store the normal temperature water pumped from the clean water tank 102 and discharge the normal temperature water to the water outlet nozzle 106 of the water purifying apparatus, or discharge the normal temperature water to the heating device 110 so that the heating device 110 heats the normal temperature water and then discharge the water from the heating device 110 to the water outlet nozzle 106 of the water purifying apparatus. The heating device 110 may be a hot tank or other component capable of performing a heating function.

Thus, the balance tank 104 is provided with the first drain port 112 and the second drain port 116, the first drain port 112 is the drain port for draining the normal temperature water to the outlet nozzle 106 of the water purification apparatus as described above, and the second drain port 116 is the drain port for draining the normal temperature water to the heating device 110 as described above. In particular, the first drain opening 112 and the second drain opening 116 are both higher than the spout 106.

Thus, the normal temperature water in the balance tank 104 will flow to the water outlet nozzle 106 under the action of its own gravitational potential energy; the water at normal temperature flowing to the heating device 110 in the balance tank 104 also flows to the heating device 110 under its own gravitational potential energy, and then flows from the heating device 110 to the water outlet nozzle 106. Through the arrangement mode, a power device is not arranged at the position of the water outlet nozzle 106, so that the design and manufacturing cost can be reduced, and the overall dimension of the water purifying equipment is correspondingly reduced.

Further, according to an embodiment of the present invention, as shown in fig. 1 to 3, a suction pump 138 is provided on the pipeline. By arranging the suction pump 138, not only can the normal-temperature water in the purified water tank 102 be pumped into the balance water tank 104 quickly and effectively, but also a certain water pressure can be formed in the balance water tank 104 because the lift of the suction pump 138 is high when the normal-temperature water in the balance water tank 104 flows to the water outlet nozzle 106 or flows into the heating device 110.

In summary, the water outlet principle of the water purifying apparatus provided by the embodiment of the invention can be summarized as follows: the normal temperature water in the balance tank 104 can flow to the water outlet nozzle 106 or the heating device 110 more smoothly and rapidly under the dual actions of the water pressure provided by the water pump 138 and the gravitational potential energy of the normal temperature water in the balance tank 104.

Further, since the water outlet nozzle 106 in the embodiment of the present invention is a common water outlet nozzle for normal temperature water and hot water, the water flow at the position of the water outlet nozzle 106 can be ensured to be constant by combining the water outlet principle.

In the embodiment of the present invention, as shown in fig. 5, the first drain port 112 and the second drain port 116 are provided at the bottom of the balance tank 104. The first water outlet 112 and the second water outlet 116 are arranged at the bottom of the balance water tank 104, so that the normal-temperature water in the balance water tank 104 can smoothly flow to the water outlet nozzle 106 or the heating device 110 under the action of gravitational potential energy of the normal-temperature water, an additional power device is avoided from being arranged to drive the normal-temperature water in the balance water tank 104 to flow, the cost is saved, and the volume miniaturization of the water purifying equipment is ensured.

Since the balance tank 104 is required to store the normal-temperature water pumped from the fresh water tank 102 as described above, the balance tank 104 is further provided with a water inlet 108, and the water inlet 108 is communicated with the fresh water tank 102 through a pipe.

Further, the water inlet 108 is arranged at the bottom of the balance water tank 104, so that the laying length of the pipeline can be reduced, the pipeline arrangement inside the water purifying equipment can be further simplified, and the volume miniaturization of the water purifying equipment can be guaranteed to a certain extent.

To further serve to prevent the heating means 110 from being dried, a blocking wall 120 is provided on the inner bottom surface of the balance tank 104 along the edge of the water inlet 108. By arranging the blocking wall 120 at the edge of the water inlet 108, the normal temperature water in the balance water tank 104 cannot flow back to the clean water tank 102, so that the water in the balance water tank 104 can flow into the water outlet nozzle 106 of the water purifier or the heating device 110 as long as water exists, and the dry burning of the heating device 110 can be avoided.

Further, referring to fig. 2 and 3 in combination, the water purifying tank 102 of the water purifying apparatus according to the embodiment of the present invention includes an upper tank 130 and a lower tank 132 which are detachably connected.

Through setting water purification tank 102 to detachable form, improved the mode through welding concatenation water purification tank 102 among the prior art, and then avoided because the welding brings the quality of water to the normal atmospheric temperature water that stores in water purification tank 102 and caused pollution scheduling problem.

Specifically, the detachable connection manner between the upper case 130 and the lower case 132 in the embodiment of the present invention may be as follows:

1. a mounting column is formed on one of the lower box body 132 and the upper box body 130, a mounting hole matched with the mounting column is formed on the other of the lower box body 132 and the upper box body 130, one end, facing the mounting hole, of the mounting column is hollow and is provided with a threaded hole, and the mounting column extends into the mounting hole and is fixed with the mounting hole through a threaded piece;

2. a first clamping piece is formed on one of the lower box body 132 and the upper box body 130, a second clamping piece matched with the first clamping piece is formed on the other of the lower box body 132 and the upper box body 130, and the first clamping piece and the second clamping piece are clamped with each other for fixing;

3. the lower case 132 and the upper case 130 are connected by interference fit.

Of course, the connection manner between the upper case 130 and the lower case 132 is not limited to the three types, and further description thereof is omitted.

Thus, the balance tank 104 is provided in the fresh water tank 102 composed of the upper tank body 130 and the lower tank body 132, and preferably, the balance tank 104 is placed in the upper tank body 130.

Further, a sealing assembly 134 is disposed between the upper case 130 and the lower case 132. The sealing assembly 134 may be a sealing ring, waterproof glue, etc. In addition, in order to ensure that the sealing ring and the waterproof adhesive can be tightly attached to the upper case 130 and/or the lower case 132, a clamping groove may be provided on one of the upper case 130 or the lower case 132, and a protrusion structure that is engaged with the clamping groove may be provided on the other of the upper case 130 or the lower case 132. And then the sealing ring, the waterproof glue and the like are arranged between the clamping groove and the protruding structure so as to improve the stability of sealing connection.

The tight sealing effect between the upper tank body 130 and the lower tank body 132 can be ensured by arranging the sealing component 134, the normal-temperature water in the water purifying tank 102 is prevented from overflowing from the gap between the upper tank body 130 and the lower tank body 132, and the use safety of the water purifying equipment is further ensured.

In a preferred embodiment, the water purification apparatus further comprises a buffer water tank 118, and an overflow port 124 is provided at a top edge of the buffer water tank 118. The surge tank 118 and the balance tank 104 are fixedly connected together, for example, they may be fixedly connected by an integral molding method or a connecting method. As described above, the surge tank 118 is also placed in the fresh water tank 102 formed of the upper tank body 130 and the lower tank body 132.

By providing the overflow port 124 at the top edge of the surge tank 118, it can be ensured that when the water in the surge tank 118 overflows, it can flow into the fresh water tank 102 through the overflow port 124. An overflow 124 may be provided at the top edge of the surge tank 118, and the overflow 124 may communicate with the fresh water tank 102.

Further, the bottom of the buffer water tank 118 is provided with an air inlet 122, and the air inlet 122 is configured to communicate with the heating device 110.

By configuring the air inlet 122 to communicate with the heating device 110, when water vapor is generated in the heating device 110, the water vapor moves upward and is finally introduced into the buffer water tank 118, so that the water vapor is prevented from flowing out through the water outlet nozzle 106, and scalding of a user is avoided.

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.

Still further, an air outlet 128 is provided on the upper tank 130, and the buffer water tank 118 is communicated 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, the buffer water tank 118 is disposed in the upper case 130 and forms a seal with the upper case 130. The sealing at this point may be achieved by the top of the buffer water tank 118 abutting against the inner wall of the upper tank 130, or by a sealing member such as a gasket disposed on the top of the buffer water tank 118.

By sealing the buffer water tank 118 and the upper tank 130, the water in the buffer water tank 118 can only flow out from the overflow port 124 and can not flow into other positions. In addition, because a seal is formed between the buffer water tank 118 and the upper tank 130, the steam discharged from the heating device 110 is prevented from flowing into other positions, and the scald of the steam to a user is further avoided. Moreover, since the buffer water tank 118 forms a certain sealing structure at this point, the water vapor can be condensed into water flowing back to the buffer water tank 118 by natural condensation in the buffer water tank 118.

Further, 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 where the top of the balance water tank 104 is located, the high-temperature steam flowing into the buffer water tank 118 does not interfere with the temperature of the normal-temperature water in the balance water tank 104, and temperature leaping among the water tanks inside the water purification apparatus is avoided.

In a preferred embodiment, the water purifying apparatus further includes a water level detecting member 136 and a pressurizing pump, the water level detecting member 136 being provided in the fresh water tank 102, and the pressurizing pump replenishing water into the fresh water tank 102 according to a detection signal of the water level detecting member 136. The water level detector 136 may be a dual float water level sensor, a photoelectric water level sensor, or a capacitive water level sensor.

The water level in the fresh water tank 102 can be detected in real time by the water level detecting member 136, and the booster pump can flexibly select pumping of normal temperature water into the fresh water tank 102 or stopping of water supply according to the detection result of the water level detecting member 136. From this, the end of intaking of booster pump can also communicate with filter equipment, former water tank in proper order. In addition, a control unit may be provided in the water purifying apparatus to control the operation or stop of the booster pump according to a detection signal of the water level detecting member 136.

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 after the normal temperature water solenoid valve is turned on, the height of the first drain port 112 in the balance water tank 104 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, so that the two are in a state of air pressure balance. Thus, the first drain 112 and the nozzle 106 can be considered as an inverted U-shaped tube, and the liquid level between the first drain 112 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 116 due to the gravitational potential energy of the water 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 116 in the balance tank 104 is higher than the water outlet nozzle 106, and the balance 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 116, 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 116 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 relationship 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 further, the dry burning prevention of the heating device 110 is realized.

Meanwhile, since there is water inside the balance tank 104, the height of the first drain port 112 is higher than that of the water outlet nozzle 106, and the balance 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, 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 simultaneously realize the functions of discharging water by using the gravitational potential energy of water and preventing the heating device 110 from being dried. Therefore, the water purifying device provided by the embodiment of the invention is a complete and inseparable whole.

The above embodiments are merely illustrative of the present invention and are not to be construed as limiting the invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalents may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention, and the technical solution of the present invention is covered by the claims of the present invention.
