Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

According to the present invention, as shown in fig. 1-6, the water dispenser may include a water inlet 101 and a water outlet 102. The water inlet end 101 may be used to connect a water purifier, a water tank, or a municipal water line, etc., and water may enter the water dispenser from the water inlet end 101. The outlet end 102 may be used to connect a water intake device, such as a faucet or water intake valve, etc., and a user may access the water through the outlet end 102.

The water dispenser may further include a water storage device 100, a hot water pipe 200, and a first pipe 310. The water storage device 100 may include a water storage tank or a pressure tank, etc. Among them, the water storage apparatus 100 shown in fig. 1, 2, 5 and 6 is a pressure tank, and the water storage apparatus 100 shown in fig. 3 to 4 is a water storage tank. The water storage tank does not have a drainage function, and water stored in the water storage tank needs gravity or a water pump to be pumped and discharged. The pressure barrel may then comprise a pressure device, which may comprise, for example, a bladder or a piston, etc. When the pressure outside the pressure barrel is larger than the extrusion force of the pressure device, the water flow extrudes the pressure device and enters the pressure barrel. When the pressure outside the pressure drum is less than the squeezing force of the pressure device, the water flow can be discharged from the pressure drum through the pressure device. As shown in fig. 4, the water storage device 100 may include a water inlet 110 and a water outlet 120 of the water storage device that are independent. As shown in fig. 1-3 and 5-6, the water inlet of the water storage device and the water outlet of the water storage device can be the same water gap, and the water gap can have different functions in different use stages of the water dispenser.

The hot water line 200 may be connected between the water outlet of the water storage device and the water outlet end 102. As shown in fig. 1-3 and 5-6, the water inlet of the water storage device and the water outlet of the water storage device are the same water gap. A flow-controlled heating device 210 may be provided on the hot water line 200. The flow-controlled heating device 210 may include a flow-limiting element 211 and a first heating element 212 in series. The first heating element 212 may comprise any heating element known in the art or that may occur in the future. The first heating element 212 may heat the flow of water therethrough. The first heating element 212 may include a heating element having a constant power, and may also include a heating element that may vary the power. The flow restriction 211 may comprise one or more of a flow control pump or a flow control valve, etc. The restriction 211 may set a restricted flow rate. The effect of the restriction 211 is that when the flow entering the restriction 211 is larger than the set restriction flow of the restriction 211, the flow of the outlet end of the restriction 211 is constant and equal to the set restriction flow. Wherein, the flow limiting amount of the flow limiting element 211 can be smaller than the inflow amount of the water inlet 101.

The water inlet of the first pipeline 310 may be connected to the water inlet end 101, and the water outlet of the first pipeline 310 may be connected to the water inlet of the water storage device. In the embodiment shown in fig. 1-3 and 5-6, since the water inlet of the water storage device and the water outlet of the water storage device are the same water inlet, the water outlet of the first pipeline 310 may also be connected to the pipeline between the water storage device 100 and the flow-control heating device 210, and the functions that can be realized by the same pipeline are the same. When a user needs to take hot water, the water flow entering the water dispenser from the water inlet 101 may first flow into the hot water pipe 200 through the first pipe 310. After entering the hot water pipeline 200, the water flow may flow to the water storage device 100 and the flow control heating device 210, respectively. Since the flow restriction of the restriction element 211 is smaller than the inlet flow of the inlet 101. Therefore, a portion of the water flow passes through the flow control heating device 210, is heated and then discharged, and is received by the user. Another part of the water flow can enter the water storage device 100 to be stored. The water storage device 100 can be used as a water buffer area to store water that cannot be discharged by the water outlet 102 in time. The water stored in the water storage device 100 may be reused. In some embodiments, the water stored in the water storage device 100 may flow to the flow-controlled heating device 210, and be heated and accessed by the user. In other embodiments, the water stored in the water storage device 100 can be used to flush components in the water dispenser, which will be described in detail below.

Therefore, in the water dispenser provided by the embodiment of the present invention, by providing the current limiting element 211, the power of the first heating element 212 can be matched with the flow rate flowing through the first heating element 212, so that the first heating element 212 is not difficult to heat the water flowing through the first heating element due to the excessive flow rate, and the power of the first heating element 212 is not increased in order to heat all the water flowing into the water dispenser. Thus, the circuit in the user's home can satisfy the power of the first heating element 212 without overloading, and the size of the first heating element 212 can be limited without affecting the size of the product by increasing the power. In addition, by providing the water storage apparatus 100, the flow of water that does not flow through the first heating element 212 can be stored. The water stored in the water storage device 100 can also be heated by the first heating element 212 to be taken by the user, so as to avoid waste. In the water dispenser with the flushing function, the water stored in the water storage device 100 can be used for flushing components in the water dispenser so as to fully utilize the water flow.

Illustratively, as shown in fig. 1-4, the water dispenser may further include a filter 400 disposed on the line between the water inlet end 101 and the first line 310. The filter assembly 400 may include various types of filter elements known in the art or that may occur in the future, such as carbon fiber filter elements, PP filter elements, ceramic filter elements, or composite filter elements formed by combining a plurality of filter elements. Wherein, the raw water port 401 of the filtering apparatus 400 can be connected to the water inlet end 101, and the water purifying port 402 of the filtering apparatus 400 can be connected to the water inlet of the first pipeline 310, that is, the filtering apparatus 400 can be connected in series to the water inlet end 101 and the first pipeline 310. Raw water entering the water dispenser from the water inlet 101 may be filtered by the filter 400 to produce purified water, which may then flow into the hot water line 200.

Therefore, the embodiment of the utility model provides a water dispenser through setting up filter equipment 400, can make the user access the water purification, improves user's use and experiences, moreover, because the water purification that produces after filter equipment 400 filters gets into hot water pipeline 200, can also reduce the pipeline in filter equipment low reaches and the possibility of the interior scale deposit of each device, has improved water dispenser's life.

Illustratively, as shown in fig. 5-6, a first check valve 311 may be disposed on the first line 310. The first check valve 311 is conducted from the water inlet of the first pipeline 310 to the water outlet of the first pipeline 310. The first check valve 311 may comprise various types of check valves known in the art or that may occur in the future. The first check valve 311 is disposed to make the water flow direction in the first pipeline 310 more definite, and in the embodiment where the water storage device 100 is a pressure tank, the water flow in the pressure tank is prevented from being influenced by the pressure and discharged from the water inlet 101.

For example, as shown in fig. 5-6, the water storage device 100 may include a pressure tank. The water dispenser may also include a second conduit 320. The water inlet of the second pipe 320 can be connected to the water outlet of the water storage device 100 (in the embodiment shown in fig. 5-6, the water inlet of the water storage device and the water outlet of the water storage device are the same water inlet). The outlet of the second pipe 320 can be connected with the raw water port 401. A second check valve 321 may be provided on the second line 320. The second check valve 321 may be communicated from the water inlet of the second pipeline 320 to the water outlet of the second pipeline 320. The second check valve 321 and the first check valve 311 may be the same or different. By providing the second check valve 321 on the second pipe 320, the water in the water storage device 100 can be guided to be discharged through the second pipe 320 and flow to the raw water port 401.

In some embodiments, during the process of receiving hot water from the water outlet end 102, since the pressure at the raw water inlet 401 is higher than the pressure at the water outlet of the first pipeline 310, the raw water is filtered by the filtering device 400, and purified water is generated and discharged to the hot water pipeline 200 through the first pipeline 310. Wherein, a part of the purified water is discharged from the water outlet end 102 and is received by a user, and the other part of the purified water enters the pressure barrel to be stored. Since the pressure at the water inlet of the second pipeline 320 is lower than that at the original water inlet 401, the water in the pressure barrel is not discharged through the second pipeline 320 in the process of taking water by a user.

Wherein, in the user water intaking process, former mouth of a river 401 stops intaking, and the water purification in the pressure vessel will flow to go out water end 102 and supply the user to take, and the pressure vessel at this moment can be as the water source, and the water in the pressure vessel is the water purification that filter equipment 400 newly prepared moreover. When the user stops receiving hot water and no water flows into the filter device 400 from the raw water port 401, the pressure of the raw water port 401 is reduced, the water outlet end 102 is stopped due to the stop of receiving water, and the water flow in the pressure barrel can be discharged through the second pipeline 320 and flows to the raw water port 401. Because the pressure barrel stores the filtered purified water in the process of taking water by a user, the purified water flowing from the pressure barrel to the raw water port 401 can flush the filter device 400, and the purified water in the pressure barrel can be used for carrying out water purification bubble membrane on the filter device 400.

Therefore, the embodiment of the utility model provides a water dispenser, owing to can wash or the water purification bubble membrane filter equipment 400, so can solve the too high problem of head cup water TDS value. In addition, compared with the prior art that a water storage tank is arranged in a water dispenser, for the user to extract heated water in the water storage tank, the water received by the user through the water dispenser is newly prepared, so that the problem of precipitation of purified water caused by long-time placement is avoided, and the influence of noise caused by arrangement of devices such as a water suction pump and the like can be avoided.

Illustratively, as shown in fig. 5-6, a first high-pressure switch 220 may also be provided on the hot water line 200. The first high pressure switch 220 may be located downstream of the outlet of the first pipe 310. The water dispenser may further include a controller. The controller may be electrically connected with the first high voltage switch 220 and the current limiting element 211.

In one embodiment, the first high pressure switch 220 may be disposed in the conduit between the flow restriction 211 and the outlet end 102. When a user desires to take water, the user may open a faucet disposed at the water outlet end 102, the pressure within the conduit in which the first high pressure switch 220 is located drops, and the first high pressure switch 220 may close, generating an electrical signal to take water. The controller can control the water pump to start or the electromagnetic valve to open according to the water getting electric signal to make the water flow into the hot water pipeline 200. In embodiments where the water dispenser includes a filter apparatus 400, the filter apparatus 400 may include a water pump. The filtering device 400 may generate purified water, and after the purified water enters the hot water pipeline 200, a part of the purified water may be heated by the flow control heating device 210 and received by a user, and another part of the purified water may enter the pressure tank. If the purified water in the pressure tank is stored to a certain amount and the user is still taking water, the pressure in the pipeline where the first high-voltage switch 220 is located rises, the first high-voltage switch 220 can be turned off, and the first high-voltage switch 220 generates an electric signal for stopping taking water.

The controller may control the filtering apparatus 400 to stop preparing the purified water according to the water stop electric signal. At this time, the clean water in the pressure barrel can be discharged. The purified water in the pressure tank can enter the flow control heating device 210 through the hot water pipeline 200, and is heated and taken by a user. When the purified water in the pressure tank is discharged to a certain amount, if the user is still taking water, the pressure in the pipeline where the first high-voltage switch 220 is located is reduced, the first high-voltage switch 220 is turned on again, and the first high-voltage switch 220 generates a water taking electric signal. The controller may control the filtering apparatus 400 to prepare purified water according to the water intake electric signal. And repeating the steps until the user stops getting water. When a user stops taking water, the filter device 400 can firstly store the generated purified water into the pressure barrel, after the pressure in the pipeline where the first high-voltage switch 220 is located rises, the first high-voltage switch 220 is switched off, the first high-voltage switch 220 generates a water taking stopping electric signal, the filter device 400 stops preparing the purified water, the purified water in the pressure barrel can enter the raw water port 401 of the filter device 400 through the second pipeline 320, and the filter device 400 is washed or a water purifying bubble film is formed. At this time, since the user stops getting water, the water outlet end 102 is in a cut-off state, and the back pressure exists at the raw water port 401 of the filter device 400, the water in the pressure tank and the hot water pipeline 200 will be in a balanced state, and the water dispenser will be in a standby state to wait for the next water getting action of the user.

Alternatively, the first high voltage switch 220 may also directly control the filter device 400. The first high voltage switch 220 may generate a get water electrical signal that is high and generate a stop get water electrical signal that is low. The filtering apparatus 400 may operate according to the high level signal and stop operating according to the low level signal. Alternatively, the first high voltage switch 220 may be connected in series with the filter device 400. When the pressure of the pipe section where the first high-voltage switch 220 is located rises to its trip threshold, the first high-voltage switch 220 trips (is turned off), and the filter device 400 is disconnected from the power supply and stops operating. On the contrary, when the pressure of the pipeline section where the first high-pressure switch 220 is located is lower, the first high-pressure switch 220 is closed, and the filtering device 400 is in the water production state.

For example, the controller may be configured to control the restriction 211 to shut off the hot water line 200 when the first high voltage switch 220 is open. In this case, the restriction 211 also has the function of opening and closing the line in which it is located, and such restriction 211 may comprise a flow control valve. The restriction 211 may close a valve disposed therein, thereby blocking the hot water line 200. The cut-off of the hot water line 200 can maintain the pressure in the line where the first high pressure switch 220 is located, and can avoid frequent start and stop of the water dispenser, and this arrangement can be applied to embodiments where a faucet or other valve capable of physical cut-off is provided at the water outlet end 102.

It should be noted that the controller described below may include an independent controller provided in each component, or may include an integrated controller capable of controlling a plurality of components. The arrangement and use of the controller is well known to those skilled in the art and is not central to the invention and is not described in excessive detail.

The water dispenser with the water dispenser is simple in working principle and easy to realize.

Illustratively, the water dispenser may include a hot water intake detection device and a hot water intake solenoid valve 240. The hot water inlet solenoid valve 240 may be disposed on the hot water line 200 between the outlet of the first line 310 and the water outlet 102.

Illustratively, the water dispenser may also include a cold water line 600. The cold water line 600 may be connected between the water inlet and water outlet ends 102 of the first line 310. The setting of cold water pipeline 600 can provide multiple water intaking for the user and select, moreover because can not set up heating element etc. on the cold water pipeline 600, so the discharge in the cold water pipeline 600 can not be restricted, and the user can connect and get cold water fast and in a large number, satisfies user's daily needs, improves user's use and experiences.

In the water dispenser with the cold water pipeline 600, the water outlet ends may include a hot water outlet end 102a and a cold water outlet end 102b, the hot water outlet end 102a may be connected to the hot water pipeline 200, and the cold water outlet end 102b may be connected to the cold water pipeline 600.

The controller may be used to control the operation of the water feeding device 500 according to the on/off of the third high voltage switch 610. The operation principle of the third high voltage switch 610 may be the same as that of the first high voltage switch 220 except that the third high voltage switch 610 detects a pressure value in the cold water line 600. When the third high-voltage switch 610 is closed, the controller controls the water feeding device 500 to be activated. The water dispenser with the arrangement is easy to realize the access of cold water.

Illustratively, a cold water inlet solenoid valve 620 may be further provided on the cold water pipeline 600. The cold water inlet solenoid valve 620 can be turned on and off by the controller.

Of course, it will be appreciated that in some embodiments, both hot water intake detection means and cold water intake detection means may be provided within the electrically controlled faucet to facilitate the user's operation of taking hot or cold water.

Illustratively, as shown in fig. 6, a third check valve 250 may be disposed on the hot water pipe 200 between the outlet of the first pipe 310 and the restriction 211. The third check valve 250 may be conducted from the water outlet of the first pipeline 310 to the flow restriction element 211. A fourth check valve 630 may be provided on the cold water line 600. The fourth check valve 630 may be conducted from the water inlet end 101 to the water outlet end 102. The water dispenser may also include an intermediate conduit 700. One end of the intermediate pipe 700 may be connected to the hot water pipe 200 between the third check valve 250 and the restriction 211. The other end of the intermediate line 700 may be connected to the cold water line 600 between the fourth one-way valve 630 and the water outlet 102. A fourth high-pressure switch 710 may also be provided on the intermediate conduit 700. The water dispenser may also include a controller and water delivery device 500. The water feeding device 500 may be provided on a pipe between the water inlet end 101 and the first pipe 310. The controller may be electrically connected to the fourth high voltage switch 710. The controller may be used to control the operation of the water feeding device 500 according to the on/off of the fourth high voltage switch 710.

The fourth high voltage switch 710 replaces the previous first high voltage switch 220 and third high voltage switch 610. Although the hot water line 200 and the cold water line 600 are communicated through the intermediate line 700, since the connection point of the intermediate line 700 and the hot water line 200 is located upstream of the flow control heating device 210, the flow restriction element 211 can still control the flow rate of water flowing through the first heating element 212, and thus does not affect the operation state of the first heating element 212. Therefore, the pressure in the hot water pipe 200 and the pressure in the cold water pipe 600 can be detected by arranging the fourth high-pressure switch 710, and the control of the water delivery device 500 is realized. The number of the high-voltage switches can be reduced, and the cost of the product is reduced.

For example, in the embodiment of the water dispenser having the cold water pipeline 600, the pipeline between the water inlet end 101 and the first pipeline 310 may be further provided with the filtering device 400. Wherein the raw water port 401 of the filter device 400 can be connected with the water inlet end 101. The clean water port 402 of the filter apparatus 400 may connect the water inlet of the first pipe 310 and the water inlet of the cold water pipe 600. Thus, the water discharged from the water dispenser through the cold water pipeline can also be purified water generated by the filtering device 400, and various options are provided for users to take water.

Illustratively, the filtration apparatus 400 may also include a reverse osmosis cartridge 410. The water dispenser may include a water supply device 500. The water supply device 500 may be disposed between the water inlet port 101 and the raw water port 401 of the filter device 400. The water feeding device 500 may include a pressurizing pump 420. The concentrate port 403 of the reverse osmosis cartridge 410 may be connected to a drain line 800. The drain line 800 may be provided with a concentrate solenoid valve 810. The reverse osmosis filter element 410 can filter raw water to generate pure water under the action of the booster pump 420. At the same time as the pure water is produced, concentrated water is also produced at the concentrate port 403, and the concentrated water is discharged from the drain line 800. In the embodiment having the pressure tank, the water in the pressure tank can flush the filter apparatus 400, and the strong water solenoid valve 810 of the drain line 800 can be in a conduction state during the flushing process, so that the flushing water can be smoothly discharged through the drain line 800. After the flushing is completed, the concentrated water solenoid valve 810 can also be turned off to prevent the purified water from being discharged, so that the reverse osmosis filter element 410 is in a state of a purified water bubble membrane. Therefore, the TDS value of the head cup water received through the water dispenser can be reduced, and the use experience of a user is improved.

In some embodiments, the water storage device 100 may further include a water storage tank, and the flow restriction 211 may include a flow control pump, as shown in fig. 3-4. The water storage tank and the water tank may be substantially the same, and neither has a function of draining water. The flow control pump can pump out the purified water stored in the water storage tank for use. The water dispenser is simple in structure and easy to realize.

Further, as shown in fig. 4, a second heating element (not shown) may be provided on the water storage tank. The water inlet of the water storage device 100 and the water outlet of the water storage device 100 may be respectively disposed at opposite ends of the water storage tank. The second heating means may be the same as or different from the first heating element 212. The second heating device is used for heating the water stored in the water storage tank. Thus, when a user receives hot water at the outlet end 102, the initial temperature of the water flowing through the flow control heating device 210 is increased, thereby increasing the heating rate of the water flow by the first heating element 212 and decreasing the heating power of the first heating element 212. The water inlet of the water storage device 100 and the water outlet of the water storage device 100 are respectively arranged at two opposite ends of the water storage tank, so that water flow can flow in the water storage tank in the process of flowing through the water storage tank, and the effect of full heating is achieved.

For example, as shown in fig. 2, in the embodiment where the water storage device 100 includes a pressure tank, the flow restriction element 211 may include not only a flow control pump but also a flow control valve. In embodiments where the flow restriction 211 is a flow control valve, the water dispenser may further include a pressure relief valve 270. A pressure reducing valve 270 may be provided on the hot water line 200 between the outlet of the first line 310 and the flow control valve. The flow control valve has the function of limiting the flow, but in a waterway with unstable pressure, the output flow of the flow control valve can be unstable. Particularly in embodiments having a pressure tank, the pressure in the piping downstream of the pressure tank may vary depending on the amount of water stored in the pressure tank. Therefore, the pressure in the upstream pipeline of the flow control valve can be stabilized by arranging the pressure reducing valve at the upstream of the flow control valve, so that the flow control effect of the flow control valve is improved, and the flow control precision is improved.

Illustratively, the first heating element 212 may be located downstream of the flow restriction element 211. This allows the first heating element 212 to be closer to the outlet end 102, thereby reducing the distance the water flows through the conduit and reducing the amount of hot water temperature lost after the water is heated.

Illustratively, the hot water line 200 may further include a faucet, and the first heating element 212 may be disposed in the faucet, that is, the faucet may integrate the first heating element 212 therein, and when water flows through the faucet, the water may be heated, which may improve the integration of the water dispenser.

Illustratively, as shown in fig. 1-4, the water dispenser may further include a flow sensor 910 and a controller. The flow sensor 910 may be disposed on the hot water line 200 between the outlet of the first line 310 and the outlet end 102. The controller may electrically connect the flow sensor 910 and the current limiting element 211. The controller may be configured to adjust the flow restriction of the flow restriction element 211 based on flow information detected by the flow sensor 910. The flow sensor 910 may detect the output flow of the restriction 211. The controller controls the flow restriction 211 according to the result detected by the flow sensor 910, so that the flow restriction 211 can output the flow more precisely. In embodiments where the first heating element 212 is a constant wattage heating element, the controller may precisely control the outlet water temperature by controlling the flow of the restricted flow. In other embodiments, the flow sensor 910 may also function to calculate the water flow, providing a hardware basis for the water dispenser to output a certain amount of water. Preferably, the flow sensor 910 may be disposed on a line between the restriction 211 and the first heating element 212.

Illustratively, the water dispenser may further include an inlet water temperature sensor 920 and a controller. An inlet water temperature sensor 920 may be provided on the hot water line 200 between the outlet of the first line 310 and the first heating element 212. The controller may be electrically connected to the incoming water temperature sensor 920. Wherein the controller may also be electrically connected to the current limiting element 211. In some embodiments, the controller may be configured to adjust the flow restriction of the flow restriction element 211 based on the first water temperature information detected by the incoming water temperature sensor 920. In other embodiments, the controller may also be electrically connected to the first heating element 212. The controller may be configured to adjust the heating power of the first heating element 212 based on the first water temperature information detected by the incoming water temperature sensor 920. Therefore, the water dispenser provided by the embodiment of the present invention can provide the initial parameters for the current limiting element 211 and/or the first heating element 212 according to the detected first water temperature information, and the initial parameters can include the current limiting flow of the current limiting element 211 and the heating power of the first heating element 212, so that when the hot water is discharged from the water outlet end 102, the user can receive the hot water at the required temperature, and the accuracy of the water outlet temperature is improved.

Illustratively, the water dispenser may further include an outlet water temperature sensor 930 and a controller. An outlet water temperature sensor 930 may be disposed on the hot water line 200 between the first heating element 212 and the outlet end 102. The controller may be electrically connected to the outlet water temperature sensor 930. In some embodiments, the controller may also be electrically connected to the current limiting element 211. The controller may be configured to adjust the flow restriction of the flow restriction element 211 based on the second water temperature information detected by the outlet water temperature sensor 930. In other embodiments, the controller may also be electrically connected to the first heating element 212. The controller may be adapted to adjust the heating power of the first heating element 212 in dependence of the second water temperature information detected by the leaving water temperature sensor 930. Of course, the controller may also adjust both the current limiting element 211 and the first heating element 212. Therefore, the water dispenser provided by the embodiment of the present invention can adjust the parameters of the current limiting element 211 and/or the first heating element 212 according to the detected second outlet water temperature information, wherein the parameters may include the current limiting flow of the current limiting element 211 and the heating power of the first heating element 212. Therefore, closed-loop control can be formed on the water outlet temperature, the water outlet temperature is more accurate, and the use experience of a user is improved.
