Description

Technical Field

[0001] The present invention relates to the technical field of drinking water equipment, in particular to a water-vapor separation mechanism and a water dispenser. Background Art

[0002] With the improvement of people's living standards, the functions of water dispensers are becoming more and more complete. In order to meet the user's demand for hot drinking water, a heating structure is provided in the water dispenser, and the drinking water will be heated in the heating structure before being discharged. During the heating process, water vapor is formed. If the water vapor expands in volume and is discharged from the water outlet together with the boiling water, splashing will occur, posing a risk of scalding. Based on this, a water-vapor separation mechanism can be set in the water dispenser to separate the boiling water and the water vapor and discharge them separately, thus avoiding splashing. However, general water dispensers have potential electrical safety hazards during the process of discharging water vapor, or there is water dripping outside the body after being used for a period of time, resulting in a poor user experience. Summary of the Invention

[0003] Aiming at the problem of poor user experience, the present invention provides a water-vapor separation mechanism and a water dispenser, which can not only avoid the occurrence of electrical safety problems, but also avoid water dripping outside the body, effectively improving the user experience.

[0004] A water-vapor separation mechanism, comprising:

[0005] A water tank, which is configured to have a water storage cavity, a water outlet and a suction port, and both the water outlet and the suction port are communicated with the water storage cavity to form a channel;

[0006] A heating element, which is configured to have a heating cavity, a water inlet and a water outlet, and both the water inlet and the water outlet are communicated with the heating cavity to form a heating channel, and the water inlet is communicated with the water outlet of the water tank;

[0007] A water nozzle assembly, which has a water passage cavity and a ventilation cavity communicating with each other. The hole that makes the water passage cavity and the ventilation cavity communicate is a gas passage hole, and the gas passage hole is above the highest water level of the water passage cavity. The wall of the water passage cavity is provided with a water inlet hole and a water outlet hole, and the wall of the ventilation cavity is provided with a ventilation hole. The ventilation hole is communicated with the suction port of the water tank, and the water inlet hole is communicated with the water outlet of the heating element. The boiling water entering from the water inlet hole can be discharged outside the water nozzle assembly from the water outlet hole, and the water vapor entering from the water inlet hole can be discharged outside the water nozzle assembly from the ventilation hole.

[0008] The above solution provides a water vapor separation mechanism. When in use, the water in the water tank can enter the heating element for heating, and the heated water then flows into the water passage cavity. When the heated water flows into the water passage cavity, the water vapor formed by heating will spread into the ventilation cavity through the air holes. The boiling water will be discharged from the water outlet hole for the user to drink. As the boiling water is discharged from the water outlet hole outside the water nozzle assembly, the water volume in the water storage cavity of the water tank gradually decreases, and a negative pressure is formed in the water storage cavity. Under the action of the negative pressure, the water vapor separated from the gas-liquid in the ventilation cavity is sucked into the water storage cavity from the ventilation hole and the suction port. Thus, it effectively avoids the situation of water dripping outside the body or the occurrence of electrical safety hazards after the water vapor separated from the gas-liquid is discharged. By effectively avoiding the occurrence of the above situations, the user experience is effectively improved.

[0048] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation mode of the present invention will be made in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0049] As Figure 1 shown, in one embodiment, a water vapor separation mechanism 10 is provided, including:

[0050] A water tank 11, as Figure 2 shown, the water tank 11 is configured to have a water storage cavity, a water outlet 111 and an air intake 112, and both the water outlet 111 and the air intake 112 communicate with the water storage cavity to form a channel. When the water in the water storage cavity is discharged from the water outlet 111, resulting in a negative pressure in the water storage cavity, the gas outside the water storage cavity will be sucked into the water storage cavity from the air intake 112.

[0051] Furthermore, as Figure 1 shown, the water vapor separation mechanism 10 includes a heating element 12, the heating element 12 is configured to have a heating cavity, a water inlet and a water drain, and both the water inlet and the water drain communicate with the heating cavity to form a heating channel, and the water inlet is communicated with the water outlet 111 of the water tank 11.

[0052] Furthermore, as Figure 1 shown, the water vapor separation mechanism 10 further includes a water nozzle assembly 13. As Figures 3 to 6As shown, the water nozzle assembly 13 has a water passage cavity 133 and a ventilation cavity 134 that communicate with each other. The hole that enables the water passage cavity 133 and the ventilation cavity 134 to communicate is the air passage hole 1411, and the air passage hole 1411 is above the highest water level of the water passage cavity 133. In other words, generally, the water in the water passage cavity 133 will not overflow the air passage hole 1411, and the gas in the water passage cavity 133 and the ventilation cavity 134 can flow through each other.

[0053] As Figures 3 to 9 shown, the cavity wall of the water passage cavity 133 is provided with a water inlet hole 1311 and a water outlet hole 1321. The boiling water that enters the water passage cavity 133 from the water inlet hole 1311 can be discharged from the water outlet hole 1321 outside the water nozzle assembly 13. The water inlet hole 1311 communicates with the drain outlet of the heating element 12.

[0054] The cavity wall of the ventilation cavity 134 is provided with a ventilation hole 1322, and the ventilation hole 1322 communicates with the air suction port 112 of the water tank 11. The water vapor that enters from the water inlet hole 1311 can be discharged from the ventilation hole 1322 outside the water nozzle assembly 13.

[0055] A water-vapor separation mechanism 10 provided by the above solution, when in use, the water in the water tank 11 can enter the heating channel in the heating element 12, and the water is heated when passing through the heating channel. The heated water then flows into the water passage cavity 133. When the heated water is flowing into the water passage cavity 133, the water vapor formed by heating in the heating cavity first enters the water passage cavity 133 together, and then spreads into the ventilation cavity 134 through the air passage hole 1411. The boiling water in the water passage cavity 133 will be discharged from the water outlet hole 1321 for the user to drink. As the boiling water is discharged from the water outlet hole 1321 outside the water nozzle assembly 13, the water volume in the water storage cavity of the water tank 11 gradually decreases, and a negative pressure is formed in the water storage cavity. Under the action of the negative pressure, the water vapor separated from the gas-liquid in the ventilation cavity 134 is sucked into the water storage cavity from the ventilation hole 1322 and the air suction port 112. Thus, it effectively avoids the situation of water dripping outside the body or the occurrence of electrical safety hazards after the water vapor separated from the gas-liquid is discharged. By effectively avoiding the occurrence of the above situations, the user experience is effectively improved.

[0056] Specifically, in some embodiments, the height of the water tank 11 is higher than the height of the heating element 12, so that the water in the water tank 11 can flow to the water inlet under the action of gravity. Or in some other embodiments, as Figure 1As shown, a first channel is connected between the water outlet 111 of the water tank 11 and the water inlet of the heating element 12, and a first water pump 15 is provided on the first channel. The first water pump 15 can provide power for the water flow, so that the water in the water storage cavity flows towards the water inlet.

[0057] Optionally, a second channel is connected between the drain outlet of the heating element 12 and the water inlet hole 1311 of the water nozzle assembly 13, and a second water pump is provided on the second channel. The second water pump can also provide power for the water flow, so that the water in the water storage cavity flows through the heating element 12 towards the water inlet hole 1311.

[0058] Specifically, in some embodiments, the ventilation cavity 134 and the water passage cavity 133 are arranged in sequence in the longitudinal direction. In other words, the ventilation cavity 134 is the upper part space in the water nozzle assembly 13, and the water passage cavity 133 is the lower part space in the water nozzle assembly 13. There is no clear boundary between the ventilation cavity 134 and the water passage cavity 133. When the boiling water heated by the heating element 12 enters the water nozzle assembly 13, the boiling water is located in the lower space, that is, the water passage cavity 133, and the water vapor floats and is located in the upper space, that is, the ventilation cavity 134.

[0059] Optionally, in some other embodiments, the ventilation cavity 134 and the water passage cavity 133 are arranged in sequence in the horizontal direction or other directions. At this time, in order to prevent the boiling water in the water passage cavity 133 from flowing into the ventilation cavity 134, the space in the water nozzle assembly 13 can be separated by a partition member 14, so as to obtain the ventilation cavity 134 and the water passage cavity 133 that are not arranged in sequence longitudinally.

[0060] Specifically, as Figure 5 and Figure 6 shown, in one embodiment, a partition member 14 is provided in the water nozzle assembly 13. The partition member 14 divides the space in the water nozzle assembly 13 into the water passage cavity 133 and the ventilation cavity 134, and the air passage holes 1411 are formed on the partition member 14.

[0061] Further specifically, as Figure 5 and Figure 6 shown, the water passage cavity 133 and the ventilation cavity 134 are arranged in sequence in the left-right direction.

[0062] It should be noted that the up-down, left-right orientations of a certain device in this application refer to the up-down, left-right orientations of this device in this state when the water-vapor separation mechanism 10 is in use.

[0063] Further, in one embodiment, as Figure 4 and Figure 8As shown, an air outlet hole 1323 is further provided on the cavity wall of the ventilation cavity 134, and the water vapor entering the ventilation cavity 134 from the air passing hole 1411 can be discharged from the air outlet hole 1323. Thus, when water is replenished into the water storage cavity, the air in the water storage cavity, the heating element 12, and the water nozzle assembly 13 can be discharged from the air outlet hole 1323. Or when the water vapor separated in the ventilation cavity 134 is not in time to enter the water storage cavity, part of the water vapor can also be discharged from the air outlet hole 1323.

[0064] Further, as Figure 2 shown, a water replenishing port 113 communicating with the water storage cavity is provided on the water tank 11, and external water is replenished into the water storage cavity from the water replenishing port 113 during water replenishment.

[0065] Further, in order to prevent the gas discharged from the air outlet hole 1323 from remaining inside the water dispenser 20 and causing potential electrical safety hazards, as Figure 4 and Figure 8 shown, the air outlet hole 1323 is arranged adjacent to the water outlet hole 1321, so that the air outlet hole 1323 and the water outlet hole 1321 are similar and leak outside the water dispenser 20. Specifically, in one embodiment, as Figure 4 and Figure 8 shown, the air outlet hole 1323 is provided on the bottom wall of the water nozzle assembly 13. The water outlet hole 1321 is provided on the bottom wall of the water nozzle assembly 13.

[0066] Further, in one embodiment, as Figure 4 and Figure 8 shown, the air outlet hole 1323 and the water outlet hole 1321 are respectively located on both sides of the partition member 14. Specifically, the air outlet hole 1323 is located on the side of the partition member 14 for enclosing the ventilation cavity 134, and the water outlet hole 1321 is located on the side of the partition member 14 for enclosing the water passing cavity 133. Under the isolation of the partition member 14, the air outlet hole 1323 and the water outlet hole 1321 can be arranged adjacent to each other, and at the same time, boiling water will not flow out from the air outlet hole 1323.

[0067] Further, in one embodiment, as Figures 5 to 7 shown, the air passing hole 1411 is formed on the upper edge of the partition member 14. When the water vapor separation assembly is in use, due to the air passing hole 1411 being located at a relatively high position, it can not only meet the requirement of water vapor entering the ventilation cavity 134 from the water passing cavity 133, but also effectively isolate the boiling water outside the ventilation cavity 134.

[0068] Further specifically, the water nozzle assembly 13 can be an integrally formed structure, and the water passage cavity 133, the air passage cavity 134, the water inlet hole 1311, the water outlet hole 1321, and the air vent hole 1322 are synchronously formed during the integral forming process.

[0069] Alternatively, the water nozzle assembly 13 can also be composed of multiple parts connected together.

[0070] Further, as Figures 3 to 9 shown, in one embodiment, the water nozzle assembly 13 is divided into an upper cover 131 and a lower cover 132 by a virtual cross-section parallel to the horizontal plane, the partition member 14 is divided into an upper partition 141 and a lower partition 142 by the virtual cross-section, the upper partition 141 is connected to the upper cover 131, and the lower partition 142 is connected to the lower cover 132. At this time, the air vent hole 1411 is formed on the upper partition 141.

[0071] Specifically, in one embodiment, the water nozzle assembly 13 includes the upper cover 131 and the lower cover 132. The upper cover 131 is connected to the lower cover 132. The upper cover 131 and the lower cover 132 can be welded, or can be adhesively connected or other connection methods, which will not be elaborated here.

[0072] Further specifically, the partition member 14 includes the upper partition 141 and the lower partition 142. When the upper cover 131 and the lower cover 132 are connected together, the upper partition 141 and the lower partition 142 are connected, thereby together forming the air passage cavity 134 and the water passage cavity 133. Specifically, similar to the connection method between the upper cover 131 and the lower cover 132, the upper partition 141 and the lower partition 142 can also be connected by welding, or adhesively connected or other connection methods, which will not be elaborated here.

[0073] Further, a seal can be provided between the upper partition 141 and the lower partition 142, and the seal is pressed between the upper partition 141 and the lower partition 142.

[0074] Further specifically, as Figure 5 and Figure 6 shown, the water inlet hole 1311 is formed on the upper cover 131. The air vent hole 1322 is formed on the lower cover 132. The water outlet hole 1321 and the air outlet hole 1323 are both formed on the lower cover 132.

[0075] Further, in one embodiment, the portion of the bottom wall of the water passage chamber 133 closest to the water inlet hole 1311 is higher than the portion of the bottom wall of the water passage chamber 133 where the water outlet hole 1321 is provided, so that the boiling water entering the water passage chamber 133 from the water inlet hole 1311 can automatically flow to the water outlet hole 1321.

[0076] Specifically, in one embodiment, the bottom wall of the water passage chamber 133 can be a complete inclined plane, and the inclination direction of this inclined plane satisfies that the position where the water outlet hole 1321 is provided is the lowest position of this inclined plane.

[0077] Alternatively, in another embodiment, the bottom wall of the water passage chamber 133 is stepped, and the water levels of each step gradually decrease in the direction close to the water outlet hole 1321.

[0078] Further, in one embodiment, as Figure 4 、 Figure 8 and Figure 9 shown, a water blocking member 16 is provided in the water passage chamber 133. The water blocking member 16 divides the water passage chamber 133 into two interconnected water passage spaces, and the opening connecting these two water passage spaces is a water passage opening. The position where the water passage opening is located is higher than the position where the water outlet hole 1321 is located, and the position where the water passage opening is located is lower than the position where the air passage hole 1411 is located;

[0079] A spare water hole 1324 is further provided on the chamber wall of the water passage chamber 133. The spare water hole 1324 is communicated with one of the water passage spaces, and the spare water hole 1324, this water passage space and the water passage opening together form a spare water outlet passage;

[0080] The water inlet hole 1311 and the water outlet hole 1321 are both communicated with the other water passage space to form a main water outlet passage;

[0081] The spare water hole 1324 is located on one side of the water blocking member 16, and the water inlet hole 1311 and the water outlet hole 1321 are both located on the other side of the water blocking member 16.

[0082] When the amount of water in the water passage chamber 133 is small and the water level does not exceed the water level where the water passage opening is located, the boiling water entering from the water inlet hole 1311 mainly flows in the main water outlet passage and flows out from the water outlet hole 1321 to ensure the continuity of the water flow when the user receives water. When the amount of water in the water passage chamber 133 is large and the water level exceeds the water level where the water passage opening is located, part of the boiling water overflows the water passage opening and enters the spare water outlet passage and flows out from the spare water hole 1324. To prevent the boiling water from entering the air passage chamber 134 from the air passage hole 1411 when the amount of water in the water passage chamber 133 is too large.

[0083] More specifically, in one embodiment, as Figure 8 and Figure 9 shown, the standby water hole 1324 is formed on the bottom wall of the water nozzle assembly 13. The water blocking member 16 is connected to the bottom wall and the side wall of the water passing cavity 133. The water blocking member 16 surrounds the standby water hole 1324 on the side of the water blocking member 16 facing away from the water inlet hole 1311 and the water outlet hole 1321. A water passing port is formed by a space between the water blocking member 16 and the top wall of the water passing cavity 133. Only when the water level in the main water outlet channel is higher than the height of the water blocking member 16, the boiling water in the main water outlet channel will flow into the standby water outlet channel.

[0084] Furthermore, as Figure 8 and Figure 9 described, in one embodiment, the standby water hole 1324, the water outlet hole 1321, and the air outlet hole 1323 are arranged in sequence in the left-right direction. The standby water hole 1324 and the water outlet hole 1321 are separated by the water blocking member 16, and the water outlet hole 1321 and the air outlet hole 1323 are separated by the partition member 14.

[0085] Specifically, as Figure 8 and Figure 9 shown, in one embodiment, the water blocking member 16 includes a first water blocking rib 161 and a second water blocking rib 162 both disposed on the bottom wall of the water passing cavity 133. The first water blocking rib 161 is a straight plate type. The second water blocking rib 162 is an arched plate, and the central axis of the second water blocking rib 162 coincides with the axis of the water outlet hole 1321. One straight edge of the second water blocking rib 162 coincides and is connected with one straight edge of the first water blocking rib 161, and the other straight edge of the second water blocking rib 162 is connected with the side wall of the water passing cavity 133. The first water blocking rib 161 is arranged in the left-right direction, and the straight edge of the first water blocking rib 161 facing away from the second water blocking rib 162 is connected with the side wall of the water passing cavity 133.

[0086] Furthermore, as Figure 5 and Figure 6 shown, the partition member 14 is a plate-like structure. The partition member 14 includes two first partition ribs arranged in the front-back direction and a second partition rib arranged in the left-right direction. The two first partition ribs are offset in the left-right direction and are arranged in sequence in the front-back direction. The second partition rib connects the two first partition ribs. The water outlet hole 1321 and the air outlet hole 1323 are respectively located on the left and right sides of one of the first partition ribs.

[0087] Furthermore, in one embodiment, as Figure 7As shown, a stopper 17 is further provided in the water passage cavity 133. The stopper 17 at least partially blocks the water inlet direction of the water inlet hole 1311, and there is a water passing gap for boiling water to pass between the stopper 17 and the cavity wall of the water passage cavity 133.

[0088] The boiling water entering from the water inlet hole 1311 will partially impact on the stopper 17, thus preventing the boiling water from directly impacting the water outlet hole 1321. Moreover, during the process of the boiling water impacting the stopper 17, the sufficiency of gas-liquid separation can be further improved. After the boiling water impacts and decelerates, it will continue to flow from the water passing gap to the water outlet hole 1321.

[0089] Specifically, as Figure 7 shown, in one embodiment, the stopper 17 is connected to the upper cover body 131, and the lower end surface of the stopper 17 is flush with the virtual cross-section.

[0090] Further, in one embodiment, as Figure 7 shown, in the water flow direction from the water inlet hole 1311 to the water outlet hole 1321, the stopper 17 is located downstream of the air passing hole 1411. Thus, the water vapor further separated by impacting the stopper 17 can more smoothly flow into the ventilation cavity 134 from the air passing hole 1411.

[0091] More specifically, in one embodiment, the ventilation hole 1322 is formed at the connection between the bottom wall and the side wall of the ventilation cavity 134, or the ventilation hole 1322 is formed on the bottom wall of the ventilation cavity 134.

[0092] The part of the bottom wall of the ventilation cavity 134 that intersects with the hole wall of the ventilation hole 1322 is the lowest point of the bottom wall of the ventilation cavity 134. Thus, if the water vapor condenses to form condensate in the ventilation cavity 134, the condensate will flow along the bottom wall of the ventilation cavity 134 to the ventilation hole 1322 and finally flow back to the water storage cavity.

[0093] Specifically, as Figure 9 shown, in one embodiment, the air outlet hole 1323 and the ventilation hole 1322 are arranged opposite to each other in the front-rear direction. The part of the bottom wall of the ventilation cavity 134 that intersects with the hole wall of the ventilation hole 1322 is the lowest point of the bottom wall of the ventilation cavity 134. Thus, the condensate mainly flows back to the water storage cavity from the ventilation hole 1322, preventing the condensate from flowing out from the air outlet hole 1323.

[0094] More specifically, in one embodiment, the bottom wall of the ventilation cavity 134 is an inclined surface, and the water level at the position where the air outlet hole 1323 is formed on this inclined surface is higher than the water level at the position where the inclined surface meets the pore wall of the ventilation hole 1322.

[0095] Alternatively, in another embodiment, the bottom wall of the ventilation cavity 134 is stepped, and the water levels of each step gradually decrease in the direction close to the ventilation hole 1322.

[0096] Furthermore, as Figure 2 shown, in one embodiment, the air suction port 112 of the water tank 11 is formed on the top wall of the water tank 11 so that when a negative pressure is formed in the water storage cavity, water vapor can be quickly sucked into the water storage cavity.

[0097] Furthermore, as Figure 10 shown, in another embodiment, a water dispenser 20 is provided, which includes the water-vapor separation mechanism 10 described above.

[0098] The water dispenser 20 provided by the above solution, by adopting the water-vapor separation mechanism 10 described in any of the above embodiments, on the one hand, separates water vapor from boiling water and discharges them from different holes respectively, thus avoiding the situation of splashing and scalding when both water vapor and boiling water are discharged from the water outlet hole 1321. On the other hand, the separated water vapor is mainly sucked into the water storage cavity, rather than being discharged outside the body of the water dispenser 20 or into the space for placing electrical components in the body housing 21 of the water dispenser 20, thereby effectively avoiding the problems of dripping water or electrical safety hazards, and further effectively improving the user experience.

[0099] Furthermore, in one embodiment, as Figures 10 to 12 shown, the water dispenser 20 further includes a body housing 21. The heating element 12 and the water tank 11 are both arranged inside the body housing 21. The body housing 21 has a socket position 211 for installing the water nozzle assembly 13, and the water nozzle assembly 13 is plugged outside the body housing 21;

[0100] The plug-in position 211 is provided with a first plug 2111 and a second plug 2112. The first plug 2111 is communicated with the drain port of the heating element 12, and the second plug 2112 is communicated with the suction port 112 of the water tank 11. The first plug 2111 and the second plug 2112 can be respectively plugged into the water inlet hole 1311 and the ventilation hole 1322 of the water nozzle assembly 13; or, the plug-in position 211 is provided with a first plug-in hole and a second plug-in hole. The first plug-in hole is communicated with the drain port of the heating element 12, and the second plug-in hole is communicated with the suction port 112 of the water tank 11. A first plug is provided at the water inlet hole 1311 of the water nozzle assembly 13, and a second plug is provided at the ventilation hole 1322 of the water nozzle assembly 13. The first plug and the second plug can be respectively plugged into the first plug-in hole and the second plug-in hole.

[0101] Thus, during assembly, first install the heating element 12 and the water tank 11 into the body housing 21, and then, after the pipelines in the body housing 21 are well connected, install the water nozzle assembly 13. Moreover, the water nozzle assembly 13 can be directly plugged into the plug-in position 211 of the body housing 21, and the installation process is simple and fast.

[0102] Further, to improve the sealing performance, as Figure 11 shown, a first sealing ring 24 is provided between the first plug 2111 and the hole wall of the plugged hole. A second sealing ring 25 is provided between the second plug 2112 and the hole wall of the plugged hole.

[0103] Further, in one embodiment, as Figures 10 to 12 shown, the water dispenser 20 further includes a connecting member 23. The water nozzle assembly 13 is provided with a lug 22. The lug 22 is provided with a first connecting hole, and a second connecting hole is provided at a position corresponding to the first connecting hole on the body housing 21. The connecting member 23 can sequentially pass through the first connecting hole and the second connecting hole to connect the water nozzle assembly 13 and the body housing 21. So that the water nozzle assembly 13 can be more reliably fixed at the plug-in position 211.

[0104] Further, in one embodiment, a filtering assembly is further provided in the body housing 21;

[0105] As Figure 11 and Figure 12As shown, a third plug connector 2113 is provided at the plugging position 211. The third plug connector 2113 communicates with the purified water outlet of the filtering component. A purified water inlet 18 is further provided on the wall of the water passing cavity 133. The third plug connector 2113 can be plugged into the purified water inlet 18; alternatively, a third socket is provided at the plugging position 211. The third socket communicates with the purified water outlet of the filtering component. As Figure 13 shown, a purified water inlet 18 is further provided on the wall of the water passing cavity 133. A third plug connector is provided at the purified water inlet 18 on the water nozzle assembly 13. The third plug connector can be plugged into the third socket.

[0106] Thus, the purified water obtained by filtering of the filtering component can enter the water passing cavity 133 from the purified water inlet 18, and then flow out from the water outlet hole 1321 for the user to drink.

[0107] Optionally, in another embodiment, as Figure 11 and Figure 12 shown, a third plug connector 2113 is provided at the plugging position 211. The third plug connector 2113 communicates with the water outlet 111 of the water tank 11. A purified water inlet 18 is further provided on the wall of the water passing cavity 133. The third plug connector 2113 can be plugged into the purified water inlet 18; alternatively, a third socket is provided at the plugging position 211. The third socket communicates with the water outlet 111 of the water tank 11. As Figure 13 shown, a purified water inlet 18 is further provided on the wall of the water passing cavity 133. A third plug connector is provided at the purified water inlet 18 on the water nozzle assembly 13. The third plug connector can be plugged into the third socket.

[0108] Thus, when the user does not need hot water, the cold water in the water storage cavity can directly enter the water passing cavity 133 from the purified water inlet 18.

[0109] Further, in one embodiment, as Figure 3 、 Figure 4 and Figure 13 described, both the water inlet hole 1311 and the ventilation hole 1322 are located at the tail of the water nozzle assembly 13.

[0110] The purified water inlet 18 can also be located at the tail of the water nozzle assembly 13.

[0111] Thus, it is convenient for the water inlet hole 1311, the ventilation hole 1322 and the purified water inlet 18 to be correspondingly assembled with the respective plug connectors at the plugging position 211 during plugging.
