Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, and in particular to a multifunctional water supply equipment. Background Technology

[0002] With the advancement of technology, multi-functional water dispensers have gradually become essential household appliances. Existing multi-functional water dispensers can provide users with purified drinking water. To meet diverse user needs, various types of machines with additional functions, such as tea-making water dispensers, tea-boiling water dispensers, ice water dispensers, and coffee dispensers, have appeared on the market.

[0003] Currently, a situation may arise where, after purchasing a multi-functional water supply machine without expansion capabilities or with only a single expansion function, if a user wants to use the water provided by the multi-functional water supply machine for other functions (such as brewing tea), the user needs to manually add the water provided by the multi-functional water supply machine to the corresponding brewing machine (such as a tea brewing machine), or the user needs to purchase a separate water supply unit with expansion capabilities (such as a tea brewing water supply unit). This results in the user spending more money and requiring the user to provide multiple installation spaces. Utility Model Content

[0119] In this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating the relative importance of the indicated features or the number of indicated technical features. Therefore, a feature specified as "first" or "second" can explicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two; "several" means at least one; unless otherwise expressly defined.

[0120] In this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "linking," "fixing," and "setting," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral molding; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can also refer to the internal communication of two components or the interaction between two components.

[0122] In this utility model, "front," "rear," "left," "right," "up," and "down" all refer to... Figure 1 , Figure 3 and Figure 5 The markings in the text shall prevail.

[0123] The following is based on Figures 1 to 16 This utility model describes a multi-functional water supply device.

[0124] In this embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the multi-functional water supply device 100 includes a water supply main unit 1 and a functional water dispenser 2. The water supply main unit 1 includes a water supply tank 11, and the functional water dispenser 2 includes a functional water tank 21 and an overflow prevention component 22. The overflow prevention component 22 includes a balancing chamber 221. The functional water dispenser 2 is detachably connected to the water supply main unit 1. The water supply main unit 1 supplies power to the functional water dispenser 2. Of course, the water supply main unit 1 may not supply power to the functional water dispenser 2. The functional water dispenser 2 may also be equipped with a battery or an external power supply port. Figure 9 As shown, the water supply unit 1 also includes a purified water supply outlet 12, a first water outlet path 171, and a second water outlet path 172. The outlet end of the water supply tank 11 is connected to the first water outlet path 171 and the second water outlet path 172 respectively. The first water outlet path 171 is connected to the purified water supply outlet 12. When the functional water dispenser 2 is connected to the water supply unit 1, the second water outlet path 172 is connected to the functional water tank 21. Under the power provided by the water replenishment pump 292, the water supply tank 11 supplies water to the functional water tank 21 through the second water outlet path 172. Of course, the water supply unit 1 may also be without the purified water supply outlet 12 and the first water outlet path 171, allowing users to remove the water supply tank 11 and pour out purified water for drinking.

[0125] like Figure 1 As shown, when the functional water dispenser 2 is installed on the water supply unit 1, the multi-functional water supply equipment 100 has a multi-functional working mode. Users can obtain purified water through the water supply unit 1, for example, by setting a purified water supply port 12 on the water supply unit 1 for users to obtain purified water, or by removing the water supply tank 11 to obtain purified water. Users can also obtain functional water (such as ice water, coffee, or tea) through the functional water dispenser 2, for example, by setting a functional water supply port 231 on the functional water dispenser 2 for users to obtain purified water. Figure 13 As shown, when the functional water dispenser 2 is removed from the water supply host 1, the multi-functional water supply equipment 100 has an independent working mode, and the user can obtain purified water through the water supply host 1.

[0126] When the functional water dispenser 2 is installed on the water supply unit 1 and the water supply tank 11 stops supplying water to the functional water tank 21 (i.e., the water replenishment pump 292 stops operating), if the water replenishment pump 292 malfunctions, or if the water replenishment pump 292 cannot completely block the second water outlet path 172 due to water pressure or other reasons, causing water in the water supply tank 11 to flow to the functional water tank 21, the water level in the functional water tank 21 will rise, eventually leading to overflow of the functional water tank 21. Even if a first valve (not shown in the figure) is installed on the second water outlet path 172 to block the second water outlet path 172 and prevent water in the water supply tank 11 from flowing to the functional water tank 21, this solution still carries the risk of overflow. That is, if the first valve malfunctions, there is still a risk that water in the water supply tank 11 will flow to the functional water tank 21. In this solution, if... Figure 2 , Figure 5 and Figure 9As shown, by adding an anti-overflow component 22 to the functional water tank 21, the anti-overflow component 22 includes a balancing chamber 221, which is connected to the functional water tank 21 and limits the highest point of the water-holding space of the balancing chamber 221 to be no lower than the highest point of the water-holding space of the functional water tank 21 and no lower than the highest water level of the water supply tank 11. That is, the highest point of the water-holding space of the balancing chamber 221 is at the same level as the highest water level of the water supply tank 11, or the highest point of the water-holding space of the balancing chamber 221 is higher than the highest water level of the water supply tank 11. In this way, when the water supply tank 11 stops supplying water to the functional water tank 21, when the water levels in the water supply tank 11 and the functional water tank 21 finally reach equilibrium, the water in the balancing chamber 221 will not exceed the highest point of its water-holding space because of the setting of the highest point of the water-holding space of the balancing chamber 221. The balancing chamber 221 can prevent water from overflowing, thereby preventing the functional water tank 21 from overflowing.

[0127] Through the above technical solution, the water supply unit 1 and the functional water dispenser 2 are used together. Users can directly obtain purified water through the water supply unit 1 and obtain functional water through the functional water dispenser 2, thus enriching the functions. Furthermore, the water supply unit 1 supplies water and electricity to the functional water dispenser 2, eliminating some structural components of the functional water dispenser 2, resulting in good integration and low cost. In addition, an anti-overflow component 22 is added to the functional water dispenser 2. By setting a balance chamber 221 connected to the functional water tank 21 and limiting the height relationship between the highest point of the water-holding space of the balance chamber 221, the highest water level of the water supply tank 11, and the highest point of the water-holding space of the functional water tank 21, the balance chamber 221 can prevent the functional water tank 21 from overflowing. The structure is simple, and the structural modifications to the functional water dispenser 2 are minimal.

[0128] It should be understood that "overflow of functional water tank 21" in this article includes, but is not limited to, water in functional water tank 21 overflowing outward through the air pressure balancing device (the function of the air pressure balancing device is to ensure the balance between the air pressure in functional water tank 21 and atmospheric pressure, so as to avoid the problem of excessive air pressure in functional water tank 21 causing the inability to supply water to functional water tank 21; the air pressure balancing device can be: an air pressure balancing pipe connected to functional water tank 21, or an exhaust hole on functional water tank connected to atmospheric pressure, etc.) or water in functional water tank 21 overflowing outward through functional water supply port 231.

[0129] The overflow prevention component 22 also includes an overflow prevention shell and a water-stopping structure 222. The overflow prevention shell and the water-stopping structure 222 are fixedly connected. The water-stopping structure 222 can be an independent component, or it can be integrally formed into the overflow prevention shell. The overflow prevention shell and the water-stopping structure 222 together form a balance chamber 221. The lowest point of the top wall 2221 of the water-stopping structure 222 constitutes the highest point of the water-holding space of the balance chamber 221. In one embodiment, the highest point of the water-holding space of the balance chamber 221 is higher than the highest water level of the water supply tank 11. This ensures that the water level in the water supply tank 11 is always lower than the highest point of the water-holding space of the balance chamber 221, making overflow prevention more reliable. Furthermore, compared to a solution where the highest point of the water-holding space of the balance chamber 221 is level with the highest water level of the water supply tank 11, this solution reduces the requirements for assembly accuracy.

[0130] In one implementation, such as Figure 5 As shown, the highest point of the water-holding space of the balance chamber 221 is higher than the highest point of the water-holding space of the functional water tank 21, which can reduce the precise requirements for the height relationship between the anti-overflow component 22 and the functional water tank 21 during assembly, and facilitate assembly.

[0131] In one implementation, such as Figures 5 to 7 As shown, the overflow prevention component 22 also includes a water outlet chamber 223. The water inlet channel 2231 of the water outlet chamber 223 is connected to the water outlet 211 of the functional water tank 21, and the water outlet channel 2232 of the water outlet chamber 223 is connected to the functional water supply port 231. The functional water in the functional water tank 21 flows into the functional water supply port 231 through the water outlet chamber 223.

[0132] Furthermore, such as Figure 5 and Figure 7 As shown, the balance chamber 221 and the outlet chamber 223 are separated by a water-stop structure 222, and the two are connected above the top wall 2221 of the water-stop structure 222. In this design, the outlet chamber 223 is provided in the overflow prevention component 22, and the functional water supply port 231, the outlet chamber 223, the balance chamber 221, and the cavity 213 of the functional water tank 21 are connected in sequence, so that the balance chamber 221 can be connected to the atmosphere.

[0133] Furthermore, the top wall 2221 of the water-stopping structure 222 is parallel to the horizontal plane, so that the entire top wall of the water-stopping structure 222 can constitute the highest point of the water-acceptable space of the balance chamber 221. Of course, the form of the top wall of the water-stopping structure 222 is not limited to this. The top wall of the water-stopping structure 222 can also be a slope or an uneven surface, so that the lowest point of the top wall of the water-stopping structure 222 constitutes the highest point of the water-acceptable space of the balance chamber 221.

[0134] In one implementation, such as Figure 2 andFigure 5 As shown, the overflow prevention components 22 are all located above the functional water tank 21, making reasonable use of the space above the functional water tank 21 and avoiding the functional water tank 21 from being too large in lateral dimension.

[0135] Furthermore, such as Figure 5 As shown, the top wall of the functional water tank 21 has a connecting port 212, and the bottom of the balance chamber 221 is connected to the connecting port 212. The highest point of the water-holding capacity of the connecting port 212 is the highest point of the water-holding space of the functional water tank 21. Specifically, as shown... Figures 5 to 7 As shown, the bottom of the balance chamber 221 is provided with an insertion interface 2213. The insertion interface 2213 is inserted into the communication port 212 to achieve communication. In this solution, there is no need to use other connecting pipes to achieve the connection between the balance chamber 221 and the functional water tank 21, and the assembly structure is simpler.

[0136] In one implementation, such as Figure 5 and Figure 7 As shown, the balancing chamber 221, the outlet chamber 223, and the functional water supply port 231 are distributed sequentially from back to front along the functional water machine 2, making full use of the internal space of the functional water machine 2 in the front-back direction. Of course, the balancing chamber 221 and the outlet chamber 223 can also be distributed along the left-right direction of the functional water machine 2.

[0137] In one implementation, such as Figure 6 and Figure 7 As shown, the water outlet channel 2232 is located below the water inlet channel 2231, which facilitates rapid water output.

[0138] Furthermore, such as Figure 5 and Figure 7 As shown, the water outlet chamber 223 includes a first chamber 2233 and a second chamber 2234. The first chamber 2233 is connected to the water inlet channel 2231, and the second chamber 2234 is located below the first chamber 2233 and is connected to the water outlet channel 2232. The lateral dimension of the first chamber 2233 is larger than that of the second chamber 2234, which facilitates the rapid entry of water from the functional water tank 21 into the first chamber 2233. Furthermore, when water in the first chamber 2233 flows into the second chamber 2234, the water flow first converges and then flows into the water outlet channel 2232, which can reduce the noise generated by the water flow.

[0139] In one implementation, such as Figure 7As shown, the first bottom wall 22331 of the first chamber 2233 extends downward at an incline towards the water outlet channel 2232. The water inlet channel 2231 is located above the first bottom wall 22331. After water enters the first chamber 2233 through the water inlet channel 2231, most of the water falls onto the first bottom wall 22331 and then flows along the first bottom wall 22331 into the second chamber 2234. In this design, the inclined arrangement of the first bottom wall 22331 can accelerate the flow of water from the first chamber 2233 into the second chamber 2234.

[0140] In one implementation, such as Figure 7 As shown, the first side wall 22341 of the second chamber 2234 is connected to the first bottom wall 22331 of the first chamber 2233. The first side wall 22341 extends inclined in the downward direction toward the water outlet channel 2232, which is conducive to the rapid flow of water in the second chamber 2234 toward the water outlet channel 2232.

[0141] In one implementation, such as Figure 7 As shown, the water outlet channel 2232 is located at the lowest point of the second chamber 2234. The second bottom wall 22342 of the second chamber 2234 extends downward in the direction toward the water outlet channel 2232, which facilitates the rapid flow of water in the second chamber 2234 to the water outlet channel 2232.

[0142] In one embodiment, the functional water dispenser 2 further includes a water level detection component, which is disposed on the overflow prevention component 22. The water level detection component is used to acquire first water level information in the balance chamber 221. If the first water level information indicates that the water level in the balance chamber 221 has reached a preset position, it is determined that the water level in the functional water tank 21 has reached a high water level. In this solution, by acquiring the water level information of the balance chamber 221, it is determined whether the water level in the functional water tank 21 has reached a high water level. Thus, the water level detection component is disposed on the overflow prevention component 22, eliminating the need to dispose of it on the functional water tank 21, thereby reducing the need for opening holes and soldering to components on the functional water tank 21.

[0143] Furthermore, such as Figure 5 As shown, the water level detection assembly includes a water level detection element (such as a water level sensor) and a float 24. The water level detection element is detachably mounted on the outer wall of the overflow prevention component 22, and the float 24 is located in the balance chamber 221. The water level detection element obtains first water level information by acquiring the position information of the float 24.

[0144] Furthermore, such as Figure 5 and Figure 6As shown, the outer wall of the overflow prevention component 22 is provided with a retainer 224, in which the water level detection element is snapped into the retainer 224, making it easy to install and remove the water level detection element. Of course, the assembly method of the water level detection element and the overflow prevention component 22 is not limited to this. For example, the water level detection element can also be fastened to the overflow prevention component 22 with bolts.

[0145] In one implementation, such as Figure 5 and Figure 7 As shown, the balance chamber 221 is provided with a protruding structure 2211, which is used to limit the high limit position of the float 24 and prevent the float 24 from being too high and leaving the detectable area of ​​the water level detection element.

[0146] In one implementation, such as Figure 6 and Figure 7 As shown, the overflow prevention component 22 includes a housing 226 and a cover 227. A balancing chamber 221 and a water outlet chamber 223 are located on the housing 226. A protruding structure 2211 is located on the cover 227. The cover 227 closes the opening of the housing 226, and the protruding structure 2211 extends into the balancing chamber 221. The overflow prevention component 22 is designed as a split structure, making it easier for the operator to install the float 24 into the balancing chamber 221.

[0147] In one implementation, such as Figure 7 As shown, the four side walls of the balance chamber 221 are respectively provided with first protruding ribs 2212; the first protruding ribs 2212 abut against the float 24, and form a gap 225 between the float 24 and the side wall. The gap 225 is used to connect the container 213, the balance chamber 221, the outlet chamber 223 and the functional water supply port 231 of the functional water tank 21 in sequence. In this way, when the water level in the functional water tank 21 is lower than the highest point of its water-holding space, the space above the water in the functional water tank 21 can be connected to the atmosphere, so that the functional water tank 21 can be replenished smoothly. That is, the balance chamber 221 also acts as a pressure balancing component, so there is no need to set a separate pressure balancing component for the functional water tank 21. In addition, the setting of the first protruding ribs 2212 can also reduce the friction between the float 24 and the wall of the balance chamber 221. Of course, the first rib 2212 can also be provided on one side, two sides, or three sides of the balance chamber 221. Preferably, at least two opposite side walls of the balance chamber 221 are provided with the first rib 2212, so that the frictional force of the float 24 on the two opposite side walls of the balance chamber 221 is equal or as equal as possible, which is beneficial to the stable movement of the float 24. Furthermore, the first rib 2212 is elongated and extends in the vertical direction, so that the airflow can pass through the gap 225 more easily, which is beneficial to the rapid adjustment of air pressure by the functional water tank 21. Of course, the shape of the first rib 2212 is not limited to this, and also includes, but is not limited to, wavy, annular, and dotted shapes.

[0148] Furthermore, such as Figure 7 As shown, the first rib 2212 extends from the low limit position of the float 24 to the high limit position of the float 24, so that the corresponding side wall of the float 24 can contact the first rib 2212 as much as possible, so as to prevent the float 24 from deviating during the rising or falling process, which would cause the gap 225 to become smaller, thereby hindering the communication between the functional water tank 21 and the atmosphere.

[0149] In yet another implementation, such as Figure 8 As shown, the outer wall of the float 24 is provided with a second protruding rib 241; the second protruding rib 241 abuts against the cavity wall of the balance chamber 221, and forms a gap 225 between the float 24 and the cavity wall of the balance chamber 221. The gap 225 is used to connect the cavity 213, the balance chamber 221, the outlet chamber 223, and the functional water supply port 231 of the functional water tank 21 in sequence. In a specific embodiment, the float 24 is cuboid in shape, and the four side walls of the float 24 are respectively provided with second protruding ribs 241 to form gaps 225 on all four sides of the float 24. Of course, the float 24 may also have second protruding ribs 241 on two or three side walls respectively.

[0150] In one implementation, such as Figure 2 , Figure 4 , Figure 5 and Figure 9 As shown, the functional water dispenser 2 also includes a water pump 291. The inlet end of the water pump 291 is connected to the outlet 211 of the functional water tank 21, and its outlet end is connected to the inlet channel 2231 of the anti-overflow component 22 through the functional water outlet water passage 2011. In this way, the water pump 291 provides power to guide the functional water in the functional water tank 21 to the inlet channel 2231.

[0151] Furthermore, such as Figure 4 As shown, the water pump 291 is located below the functional water tank 21, and the overflow prevention component 22 is located above the functional water tank 21 to make full use of the internal space of the functional water machine 2 in the height direction.

[0152] Furthermore, such as Figure 5 As shown, the water outlet 211 is located on the bottom wall of the functional water tank 21, and the water pump 291 can be directly connected to the water outlet 211, eliminating the need for pipeline connection.

[0153] In one embodiment, the functional water machine 2 is an ice water machine. The functional water machine 2 supplies ice water to the outside through the functional water supply port 231, and is more commonly used in summer.

[0154] Furthermore, the functional water tank 21 is an ice tank, such as... Figure 4 and Figure 5As shown, the functional water purifier 2 also includes a refrigeration assembly 25, which includes a refrigeration element 251. The refrigeration element 251 includes a refrigeration end 2511 and a heat dissipation end 2512. The refrigeration end 2511 is located in the cavity 213 of the functional water tank 21 and is used to absorb heat from the water in the cavity 213, cooling the water in the cavity 213 to a preset temperature. The heat dissipation end 2512 is located outside the functional water tank 21, and the heat absorbed by the refrigeration end 2511 is transferred to the outside of the functional water tank 21 via the heat dissipation end 2512 to achieve heat transfer.

[0155] Furthermore, such as Figure 5 As shown, the cooling element 251 also includes a cooling chip 2513, which is located outside the functional water tank 21. The cooling end 2511 and the heat dissipation end 2512 are respectively connected to both sides of the cooling chip 2513. The cooling assembly 25 also includes a heat insulation element 252, which is arranged around the periphery of the cooling chip 2513. In this way, the heat insulation element 252 can protect the corners of the cooling chip 2513 to prevent damage to the cooling chip 2513. At the same time, the heat insulation element 252 can also separate the cooling end 2511 and the heat dissipation end 2512. In this way, the heat absorbed by the cooling end 2511 is successively discharged through the cooling chip 2513 and the heat dissipation end 2512, avoiding direct contact between the cooling end 2511 and the heat dissipation end 2512, which would affect the cooling efficiency of the cooling end 2511. The heat insulation element 252 includes, but is not limited to, plastic structures and asbestos structures.

[0156] Furthermore, such as Figure 5 As shown, a sealing element 253 is provided between the refrigeration element 251 and the functional water tank 21. The sealing element 253 seals the assembly gap between the refrigeration element 251 and the functional water tank 21 to prevent water leakage.

[0157] In one implementation, such as Figure 5 As shown, the functional water purifier 2 also includes a fan 26, which is located on the outside of the heat dissipation end 2512 to accelerate the heat dissipation of the heat dissipation end 2512 and thus improve the cooling efficiency.

[0158] Furthermore, such as Figure 1As shown, the water supply unit 1 includes a main unit housing 13 and a raw water tank 14. The water supply tank 11 is located inside the main unit housing 13 (of course, in other embodiments, the water supply tank can also be located outside the main unit housing, for example, plugged into the main unit housing; alternatively, two water supply tanks can be provided, one inside the main unit housing and the other outside the main unit housing and plugged into the main unit housing, etc.). The purified water supply port 12 is connected to the main unit housing 13. One of the raw water tank 14 and the functional water dispenser 2 is located on the left side of the main unit housing 13, and the other is located on the right side of the main unit housing 13, to avoid the multi-functional water supply device 100 being too large in the front-to-back direction, which would limit the application scenarios of the multi-functional water supply device 100 due to the width limitation of the placement surface. Figure 2 , Figure 4 and Figure 5 As shown, the functional water tank 21, the heat dissipation end 2512, and the fan 26 are arranged sequentially from front to back along the functional water machine 2. The functional water tank 21 is located on the side closest to the internal space of the functional water machine 2, the overflow prevention component 22 is located above the functional water tank 21, and the water pump 291 is located below the functional water tank 21. This arrangement makes more efficient use of space and facilitates the miniaturization design of the functional water machine 2. Of course, the positional relationship of the functional water tank 21, the heat dissipation end 2512, and the fan 26 is not limited to this. The heat dissipation end 2512 can also be located on either the front-back or left-right side of the functional water tank 21, and the fan 26 can be located on either side of the heat dissipation end 2512.

[0159] In one embodiment, both the cooling end 2511 and the heat dissipation end 2512 are metal fins, resulting in good heat exchange performance. Preferably, to ensure heat exchange efficiency, both the cooling end 2511 and the heat dissipation end 2512 include multiple metal fins.

[0160] In one implementation, such as Figure 5 As shown, the water inlet 214 of the functional water tank 21 is located on the top wall of the functional water tank 21. The water introduced by the water inlet 214 falls at least partially onto the cooling end 2511. This part of the water can directly contact the cooling end 2511 to be cooled quickly. In addition, the water in the cavity 213 can also contact the cold air in the cavity 213 to be cooled.

[0161] Furthermore, such as Figure 5 As shown, the functional water tank 21 includes a water guide plate 215, which divides the cavity 213 to form a water inlet cavity 2131 and a cooling cavity 2132. The water inlet cavity 2131 is located above the cooling cavity 2132. The water guide plate 215 is provided with a through hole 2151, and the projection of the through hole 2151 in the vertically downward direction at least partially falls on the cooling end 2511. Specifically, as... Figure 4 and Figure 9As shown, the inlet of the water supply pump 292 is connected to the second outlet water passage 172, and its outlet is connected to the water supply passage 2010. Figure 5 and Figure 9 As shown, when the functional water tank 21 is replenished with water, the replenishment pump 292 is turned on. The clean water from the water supply tank 11 flows into the replenishment pump 292 through the second water outlet 172. The water in the replenishment pump 292 flows into the inlet 214 of the functional water tank 21 through the replenishment water channel 2010. The water flows from the inlet 214 into the inlet chamber 2131. Part of the water flows directly through the through hole 2151 and into the cooling chamber 2132. Another part of the water falls on the guide plate 215 and then flows to the through hole 2151 and enters the cooling chamber 2132.

[0162] Furthermore, such as Figure 5 As shown, the water guide plate 215 extends downward at an angle from its first end toward its second end, and a through hole 2151 is provided at the second end of the water guide plate 215 to accelerate the flow of water falling on the water guide plate 215 toward the through hole 2151.

[0163] In one implementation, such as Figure 5 As shown, the functional water tank 21 includes a tank body 216 and an insulation layer 217. The insulation layer 217 surrounds the tank body 216, and the functional water is located in the tank body 216. The insulation layer 217 is used to reduce the rate of cold loss in the cavity 213.

[0164] In one implementation, such as Figure 5 As shown, the functional water tank 21 is equipped with a temperature detection element 218, which is used to obtain the water temperature in the cooling chamber 2132. If the water temperature in the cooling chamber 2132 does not reach the preset value, the cooling component 25 continues to cool. If the water temperature in the cooling chamber 2132 reaches the preset value, the cooling component 25 stops cooling.

[0165] In one implementation, such as Figure 2 As shown, the functional water dispenser 2 also includes a manual drain port 232, which can be manually opened to drain water. When the functional water dispenser 2 malfunctions and needs maintenance, the water in the functional water tank 21 needs to be drained first. If the functional water supply port 231 malfunctions, water can be drained through the manual drain port 232 to ensure that maintenance work can be carried out smoothly.

[0166] In one implementation, such as Figure 9 As shown, a heating element 181 is provided on the first water outlet 171. When a user takes hot water, the clean water provided by the water supply tank 11 is heated by the heating element 181 and flows into the clean water supply port 12 and is distributed to the outside.

[0167] In one implementation, such as Figure 9As shown, a water stop box 182 is provided between the first water outlet 171 and the purified water supply port 12. When the water supply tank 11 stops supplying water to the purified water supply port 12, the water stop box 182 is used to prevent the water in the water supply tank 11 from overflowing. For example, the water stop box 182 can be used to prevent the water in the water supply tank 11 from overflowing outward through the purified water supply port 12, as well as other possible overflow situations where the water in the water supply tank 1 flows out into the main unit housing 13 or out of the main unit housing 13.

[0168] In one implementation, such as Figure 9 As shown, the water supply unit 1 includes a raw water inlet channel 173, a water purification filter element, and a water purification outlet channel 174 arranged in sequence. The inlet end of the raw water inlet channel 173 is used to connect to raw water (such as raw water tank 14 or municipal tap water). The outlet end of the raw water inlet channel 173 is connected to the inlet of the water purification filter element. The inlet end of the water purification outlet channel 174 is connected to the outlet of the water purification filter element. The outlet end of the water purification outlet channel 174 is connected to the inlet of the water supply tank 11. The water purification filter cartridge includes a polypropylene activated carbon composite filter cartridge 191, a reverse osmosis membrane filter cartridge 192, and an activated carbon water purification composite filter cartridge 193, arranged sequentially along the water flow direction. The polypropylene activated carbon composite filter cartridge 191 is used to intercept large particles of sediment and rust, adsorb discoloration and odor, and remove residual chlorine. The reverse osmosis membrane filter cartridge 192 is used to remove harmful substances such as heavy metals, bacteria, viruses, microorganisms, nitrates, chloroform, and carbon tetrachloride from the water. The activated carbon water purification composite filter cartridge 193 is used to inhibit microorganisms and improve taste. Of course, the water supply unit 1 may not be equipped with a water purification filter cartridge, and the water supply tank 11 can store purified water or mineral water, or other water that the user considers clean. In practical applications, the aforementioned water supply unit 1 can be a water purifier or a coffee machine, etc. Preferably, the functional water machine is a machine whose function complements that of the water supply unit. For example, when the water supply unit 1 is a water purifier, the functional water machine can be a coffee machine; when the water supply unit 1 is a coffee machine, the functional water machine can be an ice maker; when the water supply unit 1 is a water purifier, the functional water machine can be a tea maker, a tea brewer, etc.

[0169] In one implementation, such as Figure 10 and Figure 11 As shown, the water supply unit 1 also includes an expansion function module 15, through which the water supply unit 1 can be detachably connected to the functional water machine 2.

[0170] Furthermore, such as Figures 9 to 11 As shown, the extended function module 15 is equipped with a water supply main unit electrical connection element 151 and a water supply main unit water circuit connection element 152. The two ends of the second water outlet 172 are respectively connected to the water supply main unit water circuit connection element 152 and the water supply tank 11. The extended function module 15 is used to cooperate with the functional water dispenser 2. The multi-functional water supply equipment 100 has at least two operating modes, specifically a multi-functional operating mode and a standalone operating mode. Figure 1 andFigure 11 As shown, when the multi-functional water supply equipment 100 is in multi-functional working mode, a functional water dispenser 2 is installed on the extended function module 15. The water supply host 1 supplies power to the functional water dispenser 2 through the water supply host electrical connection element 151, and supplies liquid to the functional water dispenser 2 through the water supply host water circuit connection element 152. The water supply host 1 and the functional water dispenser 2 work together, and the functional water dispenser 2 can use the water purified by the water supply host 1. Figure 13 As shown, when the multi-functional water supply device 100 is in standby mode, the extended function module 15 does not have a functional water dispenser 2 installed. The water supply host 1 works independently and purifies the input water source through the water purification filter cartridge, and then provides purified water for drinking through the purified water supply port 12.

[0171] With the above setup, users can first meet their need for direct drinking purified water through the water supply unit 1; secondly, by connecting the functional water machine 2 through the expansion module 15, the water supply unit 1 can directly supply water and liquid to the functional water machine 2, saving some of the structure of the functional water machine 2, resulting in good integration and low cost.

[0172] In one implementation, such as Figure 11 As shown, the electrical connection element 151 of the water supply unit is a coupler, and the water circuit connection element 152 of the water supply unit is a stop valve. When the multi-functional water supply equipment 100 is in multi-functional working mode, the water supply unit 1 supplies power to the functional water machine 2 through the coupler and supplies liquid to the functional water machine 2 through the stop valve.

[0173] Specifically, the coupler includes at least one of a host power supply terminal, a host detection terminal, and a host signal terminal. The host power supply terminal provides power to the functional water dispenser, the host detection terminal determines whether the functional water dispenser is connected, and the host signal terminal sends information to and / or receives information from the functional water dispenser. In practical applications, different types and numbers of terminals are provided according to product requirements. For example, to facilitate user installation, the coupler includes a host power supply terminal, thus eliminating the need for an additional socket for the functional water dispenser in the installation environment. Alternatively, to save costs and facilitate user operation through a single interface, the coupler includes a host signal terminal.

[0174] Specifically, the stop valve is used to close in stand-alone mode to prevent liquid from flowing out of the water supply unit 1, and to open in multi-function mode to supply liquid to the functional water machine.

[0175] In one embodiment, the extended function module 15 is retractably installed on the water supply unit 1. Specifically, as shown in the following example... Figures 10 to 13 As shown, the water supply unit 1 includes a main unit housing 13, a water supply tank 11 located in the main unit housing 13, and an expansion function module 15 retractably installed on the main unit housing 13.

[0176] like Figure 13 As shown, when the multi-functional water supply device 100 is in stand-alone working mode, the expansion function module 15 is in a retracted state. At least the electrical connection component 151 and the water circuit connection component 152 of the water supply unit are located inside the water supply unit 1 to improve the overall aesthetics. Preferably, all expansion function modules 15 are retracted inside the water supply unit 1, which not only enhances the overall aesthetics but also avoids bumps and knocks during transportation and use, and provides dust and water protection.

[0177] like Figure 10 and Figure 11 As shown, when the multi-functional water supply equipment 100 is in the multi-functional working mode, at least the water supply host electrical connection element 151 and the water supply host water circuit connection element 152 in the extended function module 15 are located outside the water supply host 1, so that the functional water machine 2 can be smoothly connected to the extended function module 15.

[0178] Preferably, such as Figure 11 As shown, when the multi-functional water supply equipment 100 is in multi-functional working mode, at least the water supply host electrical connection element 151 and the water supply host water circuit connection element 152 in the extended function module 15 are exposed on the water supply host 1 for the installation of the functional water machine 2.

[0179] In one implementation, such as Figure 11 As shown, the extended function module 15 is located on the lower side of the water supply unit 1. The bottom of the extended function module 15 can abut against the installation platform. After docking with the water supply unit 2, it can minimize or even avoid bearing the weight exerted on it by the water supply unit 2, thereby ensuring that the extended function module 15 has the characteristics of small positional deformation and high docking accuracy during long-term use.

[0180] In yet another implementation, such as Figures 14 to 16 As shown, the extended function module 15 is disposed on one side wall of the water supply unit 1, facing the functional water dispenser 2. Specifically, the extended function module 15 is disposed on the lower part of one side of the water supply unit 1. The functional water dispenser 2 is inserted into and locked in the extended function module 15 along the left-right direction with the water supply unit electrical connection element 151 (e.g., a coupler) and the water supply unit water circuit connection element 152 (e.g., a stop valve). In this embodiment, it is worth noting that the extended function module 15 is fixedly disposed on the water supply unit 1. The protruding direction of the water supply unit electrical connection element 151 is parallel to the connection direction of the functional water dispenser 2, the protruding direction of the water supply unit electrical connection element 151 is parallel to the bottom surface of the water supply unit 1, and the extending direction of the water supply unit water circuit connection element 152 is parallel to the bottom surface, so as to allow the functional water dispenser 2 to be inserted laterally. Figure 11In another embodiment shown, the functional water dispenser 2 is connected to the water supply host 1 in the vertical direction. The protruding direction of the electrical connection element 151 of the water supply host is perpendicular to the bottom surface of the water supply host 1, and the extending direction of the water circuit connection element 152 of the water supply host is perpendicular to the bottom surface. In this way, the problem of the functional water dispenser 2 moving due to the vibration of the booster pump during the operation of the whole machine can be avoided.

[0181] In one implementation, such as Figure 11 and Figure 13 As shown, for the storage of the expansion function module 15, the water supply unit 1 is provided with a receiving cavity 131. The receiving cavity 131 can penetrate the side wall of the water supply unit 1, so as to facilitate the switching of the relative position of the expansion function module 15 between the standalone working mode and the multi-functional working mode.

[0182] Furthermore, to facilitate easy switching of the relative position of the expansion function module 15, a slide rail (not shown in the figure) is provided in the accommodating cavity 131, and a slide groove (not shown in the figure) is provided on the expansion function module 15. The slide rail and the slide groove cooperate with each other to allow the expansion function module 15 to be slidably mounted on the water supply unit 1. Of course, the installation positions of the slide rail and the slide groove can be replaced, with the main purpose of facilitating installation. Alternatively, a pull-out method using a wedge block and a groove, or a pull-out method using a cylinder to push and retract, can be adopted, with the main purpose of meeting the characteristics of low cost and small installation space occupation.

[0183] In one embodiment, the extended function module 15 is retractably installed on the main unit housing 13 of the water supply unit 1, such as... Figure 12 and Figure 13 As shown, the main housing 13 also includes a decorative cover 132. When the multi-functional water supply device 100 is in stand-alone working mode, the decorative cover 132 covers the extended function module 15. In the method of housing the extended function module 15 within the receiving cavity 131, due to the design requirements of the assembly space, the functional part of the extended function module 15 is still exposed to the air. For users with high cleanliness requirements, the introduction of the decorative cover 132 allows for complete sealing of the functional part of the extended function module 15 after the closing action, thereby achieving a better cleanliness maintenance effect and providing users with a variety of operational needs.

[0184] In an embodiment where the extended function module 15 is installed on the water supply unit 1 and housed in the receiving cavity 131, the decorative cover 132 can be inserted into the receiving cavity 131 to achieve the closing action of the extended function module 15.

[0185] In one implementation, such as Figure 11As shown, the extended function module includes a housing 153, and an electrical connection element 151 (such as a coupler) and a water circuit connection element 152 (such as a stop valve) of the water supply unit are disposed on the housing 153. Specifically, the functional parts of the electrical connection element 151 and the water circuit connection element 152 of the water supply unit are both disposed on the upper surface of the housing 153. The purpose of this is that during the connection process between the selected functional water dispenser 2 and the water supply unit 1, the connection action is vertically downward and fits against the side wall of the water supply unit 1. In this way, the connection action between the functional water dispenser 2 and the extended function module 15 is completed at the same time as the connection action is completed, which is simple to operate and precise in connection.

[0186] Furthermore, the electrical connection element 151 of the water supply unit includes at least one electrical conductor, and the water circuit connection element 152 of the water supply unit is a stop valve and includes a valve core. Even further, as... Figure 11 As shown, at least one waterproof component 154 is provided on the housing 153. The waterproof component 154 is correspondingly arranged with the conductive component, and at least one conductive component is located below its corresponding waterproof component 154. Preferably, the waterproof component 154 is an openable waterproof silicone sheet. The waterproof silicone sheet has openings with cross-shaped, star-shaped, or other structures. During the docking process, the corresponding plug of the functional water pump 2 squeezes the opening of the waterproof silicone sheet, passes through, and docks with the conductive component.

[0187] In one embodiment, the water circuit connection element 152 of the water supply unit is in fluid communication with the water supply tank 11. The water purification filter element is located inside the water supply unit 1, and at least a portion of the water purification outlet 12 is located outside the water supply unit 1, with the water purification outlet 12 in fluid communication with the water supply tank 11.

[0188] In one implementation, such as Figure 3 As shown, the functional water dispenser 2 includes a functional water dispenser housing 27 and an attachment docking module 28. The attachment docking module 28 is disposed on the functional water dispenser housing 27 and includes an attachment electrical docking element 281 and an attachment water circuit docking element 282. Figure 3 and Figure 11 As shown, the attached electrical connection element 281 is used to connect with the water supply unit's electrical connection element 151 to receive electrical signals from the water supply unit 1. The attached water connection element 282 is used to connect with the water supply unit's water connection element 152 to receive liquid supplied by the water supply unit 1. Specifically, when the functional water dispenser 2 is installed on the water supply unit 1 via the expansion function module 15, the attached electrical connection element 281 connects with the water supply unit's electrical connection element 151, and the attached water connection element 282 connects with the water supply unit's water connection element 152.

[0189] Furthermore, such as Figure 3 and Figure 11 As shown, the electrical connection element 151 of the water supply unit is a coupler, and the attached electrical connection element 281 is a coupling interface.

[0190] In one implementation, such as Figure 3 and Figure 9 As shown, the water replenishment pump 292 of the functional water dispenser 2 is connected to the attached water circuit connection element 282. The water replenishment pump 292 is located inside the functional water dispenser housing 27 and connected to the functional water tank 21. As a driving source, the water replenishment pump 292 can pump water from the source so that the purified water in the water supply tank 11 can be introduced into the functional water tank 21. Furthermore, it differs from existing tea-brewing water supply units that do not have a pump structure.

[0191] In one implementation, such as Figure 1 As shown, the multi-functional water supply device 100 also includes a display 16, which displays different interfaces when the multi-functional water supply device 100 is in different working modes. Furthermore, the display 16 is positioned close to the purified water supply port 12, making it convenient for users to observe the display interface during water dispensing.

[0192] In one embodiment, the functional water maker is a tea maker, tea brewer, or coffee maker. Of course, the functional water maker can be one or more of these functions, and can be selectively combined according to actual needs, resulting in a variety of functions.

[0193] In this embodiment, as Figure 1 and Figure 2 As shown, the water supply tank 11 is detachably installed in the main unit housing 13, facilitating replacement, disinfection, and cleaning. The water supply unit 1 also includes a raw water tank 14, which is detachably installed on the main unit housing 13. Water from the raw water tank 14 is purified by a filter element and then supplied to the water supply tank 11. Preferably, the raw water tank 14 is located on the side of the water supply unit 1 facing away from the functional water dispenser 2. This symmetrical arrangement of the raw water tank 14 and the functional water dispenser 2 with respect to the water supply unit 1 shortens the operating distance of the components of the water supply unit 1 and is more aesthetically pleasing.

[0194] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this utility model that may not be explicitly described.
