[0236] This utility model has the following technical effects:

[0237] This invention provides a water purifier distributor. A first water-blocking structure is installed on the bottom wall of the water outlet channel of the distributor. This allows a small amount of water to remain in the outlet channel after each dispensing, forming a liquid seal. Outside air cannot penetrate this liquid seal and enter the water purifier distributor, thus preventing bacterial growth and ensuring safe drinking water. Simultaneously, by configuring the first bottom wall to slope downwards towards the dispensing port, smooth water flow is ensured. Furthermore, by configuring the second bottom wall to slope downwards away from the dispensing port, water can easily flow back into the channel on the side of the first water-blocking structure away from the dispensing port after each dispensing, reducing water accumulation in the outlet channel. This reduces waiting time for the next hot water dispensing and improves the accuracy of the hot water temperature. Attached Figure Description

[0277] First Implementation Method

[0278] The following is based on Figures 1 to 30 This invention describes in detail the water purifier according to the first embodiment of the present invention.

[0279] In this embodiment, such as Figure 1 , Figure 18 , Figure 29 and Figure 30 As shown, the water purifier 1000 includes a main unit 100, which includes a water circuit assembly 1, a first pump body 21, a filter element assembly 3, a purified water container 41, a hot water container 42, and a casing 5. Figure 18 As shown, the water system component 1 includes a first water system 11. The inlet of the first water system 11 is used to connect to a water source, which includes, but is not limited to, external tap water (such as municipal tap water) or water tank supply. A first pump body 21 is installed on the first water system 11. The first pump body 21 is used to provide power for the water flow in the first water system 11. Because the first pump body 21 needs to provide a large amount of water power, its size is relatively large. Figure 18 As shown, the filter element assembly 3 is connected to the first water channel 11 to purify the water source. Figure 1 and Figure 18 As shown, the water purification container 41 is used to store clean water treated by the filter element assembly 3, and the hot water container 42 is used to provide hot water. Figure 3 and Figure 4 As shown, the housing 5 has a first accommodating area 521 and a second accommodating area 522 arranged vertically in sequence. The first accommodating area 521 can be located above or below the second accommodating area 522. Figure 1 and Figure 5 As shown, the length of the filter element assembly 3 extends along the first direction a, and the filter element assembly 3 is laterally arranged in the first accommodating area 521. The first pump body 21, the purified water container 41 and the hot water container 42 are separately arranged in the second accommodating area 522 along the first direction a. The first direction a (the length direction of the filter element assembly 3) and the second direction b (the width direction of the filter element assembly 3) are perpendicular to each other and are both parallel to the horizontal plane.

[0280] The first pump body 21 includes a first motor housing 211 and a pump head 212. The pump head 212 is located above the first motor housing 211. The total projected area of ​​the first motor housing 211 in the second direction b is S1, and the projected area of ​​the first motor housing 211 in the second direction b onto the water purification container 41 is S2. S2 is greater than or equal to one-fifth of S1, so that the water purification container 41 partially surrounds the first pump body. Specifically, as shown... Figure 2 , Figure 5 and Figure 29As shown, the cross-section of the housing 5 is roughly rectangular. The housing 5 has two side walls in the second direction b. Since the size of the first pump body 21 is smaller than the spatial size of the housing 5 in the second direction b, the first pump body 21 is positioned close to the inner wall of the housing 5 in the second direction b, so that there is a space between the other inner wall of the housing 5 in the second direction b and the first pump body 21. That is, there is a space between the first pump body 21 and the housing 5 in the second direction b. Furthermore, part of the structure of the water purification container 41 extends into this space. In this way, the water purification container 41 partially surrounds the first pump body 21, improving the space utilization rate.

[0281] By adopting the above technical solution, the arrangement of the larger internal components of the water purifier 1000 is optimized. Specifically, the filter element assembly 3 is arranged laterally within the first accommodating area 521, while the first pump body 21, the purified water container 41, and the hot water container 42 are separately arranged in the second accommodating area 522 along the first direction a. This improves space utilization and facilitates the miniaturization of the entire machine. Furthermore, by configuring the purified water container 41 to partially surround the first pump body 21, the spare space between the first pump body 21 and the casing 5 along the second direction b is effectively utilized. The arrangement of the purified water container 41 and the first pump body 21 is more compact, while also ensuring that the purified water container 41 has sufficient water storage capacity. The water purifier 1000 of this solution can be used in the kitchen, providing convenient drinking water.

[0282] It should be understood that in this document, "vertical" refers to the height direction of the water purifier 1000 when it is working normally, "horizontal" refers to the direction perpendicular to "vertical", "first direction a" refers to the length direction of the filter element assembly 3 when the water purifier 1000 is working normally, and "second direction b" refers to the width direction of the filter element assembly 3 when the water purifier 1000 is working normally. Furthermore, both "first direction a" and "second direction b" mentioned in this utility model are... Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 24 The markings in the text shall prevail.

[0283] In one embodiment, when the water purification container 41 needs to be replenished with purified water, under the power provided by the first pump body 21, the water in the first water path 11 is purified by the filter element assembly 3 and then enters the water purification container 41. The purified water in the water purification container 41 can be heated and then supplied to the hot water container 42, or the purified water can enter the hot water container 42 and then be heated to become hot water. In this solution, as shown... Figure 1 and Figure 5 As shown, the first pump body 21, the water purification container 41 and the hot water container 42 are sequentially arranged in the second accommodating area 522 along the first direction a according to the water flow path, which helps to shorten the length of the water circuit assembly 1.

[0284] In one embodiment, the first pump body 21 is a booster pump with sufficient hydrodynamic force, enabling water to pass through the filter element assembly 3 with adequate power.

[0285] In one implementation, such as Figures 2 to 4 As shown, the first accommodating area 521 is located below the second accommodating area 522. The filter element assembly 3 is heavy after water flow. By placing the filter element assembly 3 in the first accommodating area 521 below the casing 5, the center of gravity of the water purifier 1000 is lower, making it more stable and reducing or avoiding vibration caused by operation.

[0286] Furthermore, such as Figure 1 , Figure 3 and Figure 5 As shown, the first pump body 21 and the hot water container 42 are both roughly cylindrical. The first pump body 21 and the hot water container 42 are both vertically arranged in the second accommodating area 522, making full use of the space in the height direction of the casing 5 and avoiding the increase in the size of the casing 5 in the first direction a due to the horizontal arrangement of the first pump body 21 and the hot water container 42.

[0287] Furthermore, such as Figure 1 and Figure 5 As shown, since the first pump body 21 is roughly cylindrical and has a large size, in order to avoid the outer contour of the filter element assembly 3 interfering with the setting of the first pump body 21, the first pump body 21 is positioned completely above the filter element assembly 3.

[0288] Furthermore, such as Figure 5 , Figure 6 , Figure 14 and Figure 15 As shown, the hot water container 42 includes a tank 421 and a second pump body 422 located below the tank 421. The tank 421 is used to store and keep hot water warm. The second pump body 422 is connected to a first outlet 4211 at the bottom of the tank 421 and is used to pump out the hot water from the tank 421. The tank 421 is cylindrical and is located entirely above the filter element assembly 3. The projection of the second pump body 422 in the second direction b partially falls on the filter element assembly 3. That is, there is a free space between the filter element assembly 3 and the housing 5 in the second direction b, and the second pump body 422 is partially located within this free space, further improving space utilization.

[0289] In one implementation, such as Figure 2 and Figure 5 As shown, the water purification container 41 is generally L-shaped so that it can partially surround the first pump body 21.

[0290] In one implementation, such as Figure 2 and Figure 5As shown, the first pump body 21 is generally cylindrical, and the first side wall 411 of the water purification container 41 facing the first pump body 21 is curved. The first side wall 411 partially surrounds the first pump body 21. The first side wall 411 is defined as a curved shape, which is conducive to the compact arrangement of the water purification container 41 and the first pump body 21.

[0291] Furthermore, such as Figure 1 , Figure 3 and Figure 5 As shown, the first pump body 21 is vertically arranged within the second accommodating area 522, and the first motor accommodating cylinder 211 is used to accommodate the motor and impeller. The first pump body 21 is cylindrical. The shape of the first side wall 411 matches the circumferential surface wall of the first pump body 21, making the arrangement of the water purification container 41 and the first pump body 21 more compact.

[0292] In one implementation, such as Figure 2 and Figure 5 As shown, the projection of the first motor housing 211 in the first direction a falls completely on the water purification container 41. That is, the size of the water purification container 41 in the second direction b is greater than the radial size of the first motor housing 211. Furthermore, the two outermost contours of the first motor housing 211 in the second direction b do not exceed the two outer contours of the water purification container 41 in the second direction b. In other words, by optimizing the positional relationship between the first motor housing 211 and the water purification container 41, the size of the housing 5 in the second direction b is avoided due to the arrangement of the first motor housing 211.

[0293] In one implementation, such as Figure 2 As shown, S2 is greater than half of S1, so that the water purification container 41 surrounds the first pump body 21 more.

[0294] In one implementation, such as Figure 6 As shown, the water purification container 41 partially surrounds the filter element assembly 3, and utilizes the space between the filter element assembly 3 and the housing 5 to partially accommodate the water purification container 41, thereby increasing the water storage capacity of the water purification container 41.

[0295] Furthermore, such as Figure 2 and Figure 6 As shown, the projection of the filter element assembly 3 in the second direction b partially falls on the water purification container 41. Taking the filter element assembly 3 located below the water purification container 41 as an example, the bottom of the water purification container 41 extends downward to form an extension section 413. The extension section 413 and the filter element assembly 3 are arranged sequentially in the second direction b. The extension section 413 is accommodated in the empty space between the filter element assembly 3 and the housing 5 in the second direction b, thus optimizing the arrangement.

[0296] In one embodiment, the volume of the hot water container 42 is 1.1-1.6 times the volume of the purified water container 41. Further, the volume of the hot water container 42 is 1.8-2.2L, preferably 2L, to ensure that the water purifier 1000 has a large hot water flow rate, such as ≥1.8L / min. The volume of the purified water container 41 is 1.4-1.6L, preferably 1.5L, to promptly supply purified water to the hot water container 42.

[0297] In one implementation, such as Figure 2 , Figure 5 and Figure 18 As shown, the main unit 100 includes a heating element 6 and a second water passage 15. One end of the second water passage 15 is connected to the first water inlet 4212 of the hot water container 42, and the other end is connected to the water outlet of the heating element 6. The purified water heated by the heating element 6 flows into the hot water container 42 through the second water passage 15, replenishing the hot water container 42 with hot water. Figure 2 and Figure 3 As shown, the heating element 6 is vertically arranged within the second accommodating area 522, and the heating element 6 is located on the side of the hot water container 42 away from the clean water container 41. The projection of the heating element 6 in the second direction b partially falls on the hot water container 42. Specifically, since the tank 421 of the hot water container 42 is cylindrical and the outline of the casing 5 is roughly rectangular, a space is formed between the tank 421 and the casing 5. In particular, larger spaces are formed at the two corners inside the casing 5. The heating element 6 is placed in one of these spaces, improving space utilization.

[0298] In one implementation, such as Figure 1 , Figure 2 and Figure 24 As shown, the main unit 100 includes an integrated water circuit component 7. The integrated water circuit component 7 has multiple flow channels inside, which are used to sequentially connect some of the water circuits within the main unit 100. The integrated water circuit component 7 is located on the side of the first pump body 21 opposite to the purified water container 41. The integrated water circuit component 7 is vertically arranged, and its width extends along the second direction b. Specifically, the integrated water circuit component 7 is located at the rear of the casing 5, that is, the integrated water circuit component 7, the first pump body 21, the purified water container 41, the hot water container 42, and the heating element 6 are arranged sequentially from back to front, as shown. Figure 18 , Figure 24 and Figure 26As shown, the first water channel 11 and the raw water inlet 721 of the integrated water channel component 7 are connected. The raw water provided by the water source enters the flow channel in the integrated water channel component 7 through the raw water inlet 721, and then flows to the filter element assembly 3 through the corresponding flow channel. After being purified by the filter element assembly 3, it is provided to the clean water container 41. The clean water in the clean water container 41 is heated by the heating element 6 and then provided to the hot water container 42. The integrated water channel component 7, the first pump body 21, the clean water container 41, the hot water container 42 and the heating element 6 are arranged in sequence along the water flow direction. The arrangement is reasonable and compact.

[0299] In one implementation, such as Figure 29 As shown, the housing 5 includes an outer shell 51 and an inner shell 52. The outer shell 51 forms the outer contour structure of the main unit 100 to improve the aesthetics of the main unit 100. The inner shell 52 is connected inside the outer shell 51 and forms a support structure for the internal components of the main unit 100. Specifically, as... Figure 3 As shown, the inner housing 52 is provided with a connected filter element seat 523 and a frame 524. The filter element seat 523 is provided with a first accommodating cavity, which constitutes a first accommodating area 521. That is, the first accommodating area 521 is located inside the filter element seat 523, and the second accommodating area 522 is located inside the frame 524 and above the filter element seat 523.

[0300] Furthermore, such as Figure 1 and Figure 3 As shown, the inner shell 52 has a first support frame 526 and a second support frame 527 arranged sequentially along the first direction a. The first support frame 526 has a second receiving cavity 5221 for accommodating the first pump body 21, and the second support frame 527 has a third receiving cavity 5222 for accommodating the hot water container 42. The purified water container 41 partially surrounds the first support frame 526. A fourth receiving cavity 5223 is formed between the outer wall of the second receiving cavity 5221 (i.e., the outer wall of the first support frame 526), ​​the outer wall of the third receiving cavity 5222 (i.e., the outer wall of the second support frame 527), and the outer wall of the filter element seat 523. The purified water container 41 is disposed in the fourth receiving cavity 5223. Figures 1 to 4 As shown, the front side plate 525 of the inner shell 52 is located on the side of the hot water container 42 away from the clean water container 41. The outer wall of the third accommodating cavity 5222 and the inner wall of the front side plate 525 form a fifth accommodating cavity 5224. The heating element 6 of the main unit 100 is disposed in the fifth accommodating cavity 5224. The second accommodating cavity 5221, the third accommodating cavity 5222, the fourth accommodating cavity 5223 and the fifth accommodating cavity 5224 together constitute the second accommodating area 522.

[0301] Furthermore, such as Figure 2 and Figure 3As shown, the cavity wall of the second accommodating cavity 5221 matches the shape of the outer wall of the first pump body 21, the cavity wall of the third accommodating cavity 5222 matches the shape of the outer wall of the hot water container 42, and the cavity wall of the fourth accommodating cavity 5223 matches the shape of the outer wall of the water purification container 41, so as to make full use of the internal space of the inner shell 52.

[0302] In one implementation, such as Figure 5 As shown, the filter assembly 3 includes a first filter element 31, a second filter element 32, and a third filter element 33 arranged parallel to each other. The first filter element 31 and the third filter element 33 are sequentially distributed along the second direction b, and the second filter element 32 is located above the first filter element 31 and the third filter element 33. Figure 13 As shown, the lowest point D1 of the second filter element 32 is located in the space formed by the first filter element 31 and the third filter element 33 in the second direction b. The lowest point D1 of the second filter element 32 is higher than the axis O1 of the first filter element 31 and the axis O3 of the third filter element 33, which helps to reduce the height of the filter element assembly 3. At the same time, it can avoid the gap between the first filter element 31 and the third filter element 33 from increasing too much due to the second filter element 32 extending too much into the space formed by the first filter element 31 and the third filter element 33 in the second direction b.

[0303] Furthermore, such as Figure 13 As shown, the first filter element 31, the second filter element 32, and the third filter element 33 are arranged in an isosceles triangle. That is, the lines connecting the centers of the cross-sections of the first filter element 31, the second filter element 32, and the third filter element 33 in the cross-section of the filter element assembly 3 form an isosceles triangle, which facilitates a compact arrangement and helps to reduce the space occupied by the filter element assembly 3.

[0304] Furthermore, such as Figure 5 and Figure 13 As shown, the first filter element 31 and the third filter element 33 have the same diameter, both smaller than the diameter of the second filter element 32. Specifically, the first filter element 31 is a filter element composed of PP cotton and activated carbon rod, used to intercept large particles of sediment and rust, adsorb discoloration and odor, and remove residual chlorine; the second filter element 32 is an RO reverse osmosis membrane filter element, used to remove harmful substances such as heavy metals, bacteria, viruses, microorganisms, nitrates, chloroform, and carbon tetrachloride from the water; the third filter element 33 is used to inhibit microorganisms and improve taste. Among them, the second filter element 32 is larger in size. In order to facilitate the compact arrangement of the first filter element, the second filter element 32, and the third filter element 33, the first filter element 31 and the third filter element 33 are configured with the same diameter, and the second filter element 32 is located above the first filter element 31 and the third filter element 33, and the three are arranged in an isosceles triangle.

[0305] Furthermore, such as Figure 13As shown, the axial distance between the first filter element 31 and the third filter element 33 is smaller than the diameter of the second filter element 32. By controlling the axial distance between the first filter element 31 and the third filter element 33, the size of the filter element assembly 3 in the second direction b is minimized as much as possible.

[0306] In one implementation, such as Figure 1 and Figure 4 As shown, the first accommodating area 521 includes a first filter element accommodating cavity 5211 for accommodating the first filter element 31, a second filter element accommodating cavity 5212 for accommodating the second filter element 32, and a third filter element accommodating cavity 5213 for accommodating the third filter element 33. The cavity walls of the first filter element accommodating cavity 5211, the second filter element accommodating cavity 5212, and the third filter element accommodating cavity 5213 are connected end to end to form the first accommodating area 521. That is to say, the first filter element accommodating cavity 5211, the second filter element accommodating cavity 5212, and the third filter element accommodating cavity 5213 are interconnected. This facilitates the first filter element 31, the second filter element 32, and the third filter element 33 to be arranged as close as possible to each other, which in turn facilitates the miniaturization design of the filter element holder 523 and reduces the space occupied by the filter element holder 523.

[0307] Furthermore, such as Figure 4 and Figure 5 As shown, the cavity wall of the first filter element receiving cavity 5211 matches the circumferential surface wall shape of the first filter element 31, and the first filter element receiving cavity 5211 surrounds more than half of the circumferential portion of the first filter element 31; the cavity wall of the second filter element receiving cavity 5212 matches the circumferential surface wall shape of the second filter element 32, and the second filter element receiving cavity 5212 surrounds more than half of the circumferential portion of the second filter element 32; the cavity wall of the third filter element receiving cavity 5213 matches the circumferential surface wall shape of the third filter element 33, and the third filter element receiving cavity 5213 surrounds more than half of the circumferential portion of the third filter element 33, so that the corresponding filter element receiving cavity can better surround the corresponding filter element.

[0308] Furthermore, such as Figures 2 to 4 As shown, the outer and inner walls of the filter element holder 523 have roughly the same outline, which helps to reduce the space occupied by the filter element holder 523. Furthermore, the outer wall of the filter element holder 523 can be formed with a recess 5231, which can be used to accommodate other internal components, such as the third water channel 16 of the water channel assembly 1 and the third pump body 22 provided on the third water channel 16, thereby improving space utilization.

[0309] In one implementation, such as Figure 3 and Figure 13As shown, the front panel 525 has three openings 5251, which are respectively connected to the first filter element receiving cavity 5211, the second filter element receiving cavity 5212 and the third filter element receiving cavity 5213; the first filter element 31, the second filter element 32 and the third filter element 33 are assembled through the corresponding openings 5251.

[0310] Furthermore, such as Figure 24 As shown, the integrated water system component 7 has three first slots 71, and a first matching valve 79 is installed in each first slot 71. Figure 1 , Figure 3 and Figure 24 As shown, the three first slots 71 are respectively set to correspond one-to-one with the three openings 5251. The first end of each filter element in the filter element assembly 3 is respectively snapped into the corresponding opening 5251 and the tail end is respectively snapped into the corresponding first slot 71. That is, the two ends of the corresponding filter element are snapped into each other through the corresponding openings 5251 and the first slots 71, which makes assembly convenient. In addition, the second matching valve of each filter element is inserted into the corresponding first matching valve 79, so that the filter element can communicate with the corresponding flow channel on the integrated water circuit component 7, so that water can enter and exit the filter element.

[0311] In one implementation, such as Figures 7 to 10 As shown, each filter element in the filter element assembly 3 is equipped with a corresponding locking component 34 and unlocking component 35. The locking component 34 is used to lock the corresponding filter element in the inner housing 52; the unlocking component 35 is used to unlock the locking component 34 to remove and install the corresponding filter element for filter element replacement.

[0312] Furthermore, such as Figures 7 to 10 As shown, the unlocking member 35 is movably connected to the corresponding filter element. The locking assembly 34 includes a locking member 341 and an elastic member 342. The locking member 341 is movably connected to the front side panel 525 and has a locked position and an unlocked position. The elastic member 342 applies an elastic force to the locking member 341, so that the locking member 341 is held in the locked position. At this time, the locking member 341 can restrict the removal of the corresponding filter element, thus achieving locking. The unlocking member 35 can move under external force, driving the locking member 341 to overcome the elastic force and move to the unlocked position. At this time, the locking member 341 releases the restriction on the corresponding filter element, and the user can remove the corresponding filter element.

[0313] In one embodiment, when the locking member 341 is in the locked position, it is at least partially located on the pull-out path of the corresponding filter element, thereby preventing the filter element from being pulled out and achieving locking. When the locking member 341 is in the unlocked position, it leaves the pull-out path, allowing the user to pull out the corresponding filter element. Specifically, the filter element is cylindrical, and its axial direction is parallel to the first direction a. When the filter element needs to be replaced, it is pulled out or inserted along the first direction a for easy operation. The partial structure of the locking member 341 blocking the pull-out path of the corresponding filter element means that this partial structure is located in front of the corresponding filter element along the pull-out direction. When the filter element has a tendency to move relative to the corresponding filter element receiving cavity along the pull-out direction, it abuts against the locking member 341 and cannot be pulled out. The pull-out path specifically refers to the spatial area traversed by the filter element from the start of pull-out to the end of pull-out. The end of pull-out means that the tail of the filter element is completely within the corresponding filter element receiving cavity.

[0314] Furthermore, such as Figure 8 and Figure 10 As shown, the locking element 341 is a latch, and the locking assembly 34 also includes a latching groove 343 disposed on the corresponding filter element. When the locking element 341 is in the locked position, the locking element 341 is engaged with the latching groove 343, and the corresponding filter element is locked through the engagement of the two. The locking structure is simple and the locking is stable. When the locking element 341 is in the unlocked position, the locking element 341 disengages from the latching groove 343 and the restriction is released.

[0315] Furthermore, such as Figure 7 and Figure 8 As shown, the locking assembly 34 also includes a pivot shaft 344, which is mounted on the front panel 525. The locking member 341 is mounted on the side of the front panel 525 opposite to the hot water container 42 via the pivot shaft 344. The locking member 341 can rotate around the pivot shaft 344 under external force, thereby switching between a locked position and an unlocked position. Specifically, as... Figure 8 and Figure 12 As shown, the locking member 341 has two pivot arms 3412, which are spaced apart along the second direction b, and are pivotally connected to the pivot shaft 344 respectively. The elastic member 342 can be a torsion spring, which is sleeved on the corresponding pivot shaft 344 and located between the two pivot arms 3412.

[0316] Furthermore, such as Figures 7 to 10 As shown, each filter element is provided with a filter element end cap 36, and the filter element end cap 36 is provided with a first groove 361. The unlocking member 35 includes a handle part 351 and a first mounting part 352, which is rotatably connected to the first groove 361. The first mounting part 352 is provided with a fastening surface 3521, which forms a fastening groove 343 with the groove wall of the first groove 361. The locking member 341 locks the filter element end cap 36 by locking it.

[0317] Furthermore, such as Figure 8 and Figure 10 As shown, the locking member 341 includes a locking protrusion 3411, which engages with both the locking groove 343 and the locking surface 3521. The first mounting part 352 is provided with a pushing surface 3522. When the user pulls the handle part 351, the first mounting part 352 rotates, causing the locking surface 3521 to disengage from the locking protrusion 3411 due to the rotation. Then, during the rotation, the pushing surface 3522 pushes the locking protrusion 3411, causing the locking member 341 to rotate around the corresponding pivot shaft 344, thereby causing the locking protrusion 3411 to disengage from the locking groove 343, that is, the locking member 341 leaves the locking position and is released from locking.

[0318] Furthermore, such as Figure 9 As shown, the first mounting part 352 is provided with a shaft hole 3523, and the filter element end cover 36 is provided with a mounting shaft 362. The mounting shaft 362 is located in the first groove 361. The first mounting part 352 and the filter element end cover 36 are rotatably connected through the shaft hole 3523 and the mounting shaft 362 to achieve assembly. The axis of the mounting shaft 362 extends along the second direction b, and the axis of the pivot shaft 344 extends along the first direction a. In this way, when the handle part 351 drives the first mounting part 352 to rotate, the pushing surface 3522 can push the locking protrusion 3411.

[0319] In one implementation, such as Figure 7 and Figure 8 As shown, each filter element is equipped with two locking elements 341 on both radial sides to ensure the stability of the locking.

[0320] Furthermore, such as Figure 8 , Figure 11 and Figure 12 As shown, two locking members 341 located between the first filter element 31 and the third filter element 33 are pivotally connected to the same pivot shaft 344 to reduce the space occupied by these two locking members 341. Specifically, the dimension of one locking member 341 in the first direction a is larger than that of the other locking member 341 in the first direction a. The two pivot arms 3412 of the larger locking member are located outside the two pivot arms 3412 of the smaller locking member. The elastic member 342 is sleeved on the pivot shaft 344 and located between the two pivot arms 3412 of the smaller locking member. The two ends of the elastic member 342 abut against the two locking members 341 respectively.

[0321] In one implementation, such as Figure 14 and Figure 15As shown, the hot water container 42 includes a tank 421 and a second pump body 422. The tank 421 has a water storage chamber 4213 and a first outlet 4211 connected to the bottom of the water storage chamber 4213. The second pump body 422 is horizontally arranged below the tank 421 to save space. The second pump body 422 includes a second outlet 4221, a pump chamber 4222, and a second inlet 4223 connected in sequence. The second inlet 4223 is connected to the first outlet 4211. Water in the tank 421 flows sequentially through the first outlet 4211 and the second inlet 4223 into the pump chamber 4222, and then is pumped out through the second outlet 4221. Furthermore, since the second pump body 422 is used to transport hot water, there is a large amount of steam in the pump chamber 4222. In this solution, by setting the second outlet 4221 at the top of the pump chamber 4222, the water pressure can discharge the steam in the pump chamber 4222 from the second outlet 4221 while the water in the pump chamber 4222 is flowing, thereby reducing or avoiding the generation of trapped air.

[0322] By adopting the above technical solution, the second pump body 422 is arranged horizontally below the tank body 421, which can save the space occupied by the hot water container 42 in the height direction of the casing 5. Furthermore, by setting the second water outlet 4221 at the top of the pump chamber 4222, it can reduce or avoid the generation of trapped air in the pump chamber 4222, so as not to affect the water output of the second pump body 422 due to trapped air.

[0323] In one implementation, such as Figure 15 and Figure 17 As shown, the second pump body 422 includes a water outlet pipe 4224, and the connection between the water outlet pipe 4224 and the pump chamber 4222 forms a second water outlet 4221. The water outlet pipe 4224 slopes upward from the second water outlet 4221, which helps to accelerate the discharge of steam.

[0324] Furthermore, the angle between the outlet pipe 4224 and the horizontal plane is 5°-20°, resulting in a better steam discharge speed.

[0325] In one implementation, such as Figure 15 and Figure 16 As shown, the second pump body 422 includes a front end cover 4225 and a second motor housing 4226. The second motor housing 4226 is used to house the motor and the impeller; that is, the second pump body 422 is an impeller pump. The second outlet 4221 and the second inlet 4223 are respectively provided on the front end cover 4225 for easy processing.

[0326] Furthermore, such as Figure 16 and Figure 17As shown, the outer periphery of the front cover 4225 is provided with four first protrusions 42251, and the outer periphery of the second motor housing 4226 is provided with four second protrusions 42261. The first protrusions 42251 and the second protrusions 42261 are arranged in a one-to-one correspondence and connected by fasteners (such as screws). The second outlet 4221 of the second pump body 422 is located below the highest first protrusion 42251, which can avoid the highest first protrusion 42251 interfering with the setting of the water outlet pipe 4224. In addition, the water outlet pipe 4224 does not protrude from the first protrusion 42251, which helps to save the space occupied by the second pump body 422 in the height direction of the housing 5. Preferably, as Figure 17 As shown, to ensure stable assembly of the front cover 4225 and the second motor housing 4226, four first protrusions 42251 are evenly spaced along the circumference of the second pump body 422. Of course, the number of first protrusions 42251 is not limited to four; it can be two, three, or even more. The number of second protrusions 42261 is consistent with the number of first protrusions 42251.

[0327] In one implementation, such as Figure 15 As shown, the second pump body 422 is provided with a baffle 4227, which is located at the second water inlet 4223. When hot water flows from the tank 421 into the pump chamber 4222 through the second water inlet 4223, the hot water flow will collide with the baffle 4227. In other words, the baffle 4227 disperses the hot water flow, achieving water vapor separation by dispersing the hot water flow. The separated steam is then discharged through the second water outlet 4221 under water pressure, thus better preventing trapped air from being generated.

[0328] Furthermore, such as Figure 15 As shown, the baffle 4227 includes an axially extending rib 42271 and a radially extending rib 42272. The axially extending rib 42271 extends along the axial direction of the second pump body 422, and the radially extending rib 42272 extends along the radial direction of the second pump body 422. The number of radially extending ribs 42272 can be one, two, or even more. In one specific embodiment, three radially extending ribs 42272 are evenly spaced apart along the circumference of the axially extending rib 42271 and are respectively connected to the axially extending rib 42271. The axially extending rib 42271 has a bullet-shaped structure, and the pointed part of the axially extending rib 42271 faces the second water inlet 4223, which is conducive to better dissipating the heat dissipation water flow.

[0329] In one implementation, such as Figure 15 and Figure 16 As shown, the hot water container 42 includes a pump mounting bracket 423, and the second pump body 422 is mounted on the bottom of the tank body 421 via the pump mounting bracket 423.

[0330] Furthermore, such as Figures 14 to 16 As shown, the pump mounting bracket 423 includes a support frame 4231 and a transfer pipe 4232, and the second pump body 422 includes an inlet pipe 4228. The second pump body 422 is mounted on the support frame 4231, and the two ends of the transfer pipe 4232 are connected to the first outlet 4211 and the second inlet 4223, respectively. That is, the first outlet 4211 and the second inlet 4223 are connected through the transfer pipe 4232, which replaces the scheme of directly connecting the first outlet 4211 and the second inlet 4223. This simplifies the structural design of the inlet pipe 4228 and the first outlet 4211 of the tank body 421. The inlet pipe 4228 and the first outlet 4211 can be designed as straight pipe structures to reduce processing costs. In addition, by limiting the length of the transfer pipe 4232, heat loss during the process of hot water flow from tank 421 to second pump 422 can be reduced, and the distance between second pump 422 and tank 421 can be shortened as much as possible, saving space.

[0331] Furthermore, such as Figure 15 As shown, the inlet pipe 4228 is inserted into one end of the adapter pipe 4232 and the assembly of the two is provided with a first seal 424. The other end of the adapter pipe 4232 is inserted into the first outlet 4211 and the assembly of the two is provided with a second seal 425, so as to ensure the sealing of the entire system of the hot water container 42.

[0332] In one implementation, such as Figures 14 to 16 As shown, the support frame 4231 has an open structure, which partially surrounds the second pump body 422. When assembling the second pump body 422 and the pump mounting bracket 423, the water inlet pipe 4228 is inserted into one end of the adapter pipe 4232, and the second motor housing 4226 is supported on the support frame 4231.

[0333] In one implementation, such as Figure 14 and Figure 16 As shown, a shock-absorbing component 426 is fitted around the outer periphery of the second pump body 422 to reduce the noise generated during operation. Specifically, the shock-absorbing component 426 surrounds the outer periphery of the second pump body 422, and the support frame 4231 fixes the second pump body 422 by clamping the shock-absorbing component 426. The shock-absorbing component 426 has a certain degree of flexibility or elasticity, which on the one hand can buffer the vibration generated by the second pump body 422, and on the other hand, helps to reduce the requirements for the machining accuracy of the support frame 4231. That is to say, the deviation of the machining dimensions of the support frame 4231 can be compensated by the deformation of the shock-absorbing component 426.

[0334] Furthermore, such as Figure 16As shown, the support frame 4231 includes an arc-shaped groove 42311 and two support grooves 42312. The two support grooves 42312 are respectively connected to both sides of the arc-shaped groove 42311. The arc-shaped groove 42311 is used to support the cylinder body of the second motor housing 4226, and the two support grooves 42312 are used to support the two pairs of first protrusions 42251 and second protrusions 42261 of the second pump body 422 respectively. Figure 14 and Figure 15 As shown, the bottom of the tank 421 is mounted on the base 428, and the pump mounting bracket 423 is mounted on the bottom of the base 428. Figure 15 and Figure 16 As shown, the arc-shaped groove 42311 is provided with a first through hole 423111, the base 428 is provided with a second through hole 4281, a pair of first protrusions 42251 and second protrusions 42261 at the lowest position are inserted into the first through hole 423111, and a pair of first protrusions 42251 and second protrusions 42261 at the highest position are inserted into the second through hole 4281.

[0335] In one implementation, such as Figure 6 As shown, the second pump body 422 is located at the bottom of the tank 421 and is positioned close to one side of the tank 421. This minimizes the distance between the tank 421 and the filter element assembly 3 in the height direction of the housing 5. Specifically, in order to reduce the interference of the second pump body 422 on the reduction of the distance between the tank 421 and the filter element assembly 3, the second pump body 422 can be partially located on one side of the filter element assembly 3 in the second direction b. That is, the projection of the second pump body 422 in the second direction b partially falls on the second filter element 32 of the filter element assembly 3.

[0336] Furthermore, the axial direction of the second pump body 422 is parallel to the first direction a, that is, the second pump body 422 is arranged parallel to the second filter element 32. This allows the second pump body 422 to be partially located on the radial side of the second filter element 32, thereby reducing the interference of the second pump body 422 on the reduced distance between the tank 421 and the filter element assembly 3. Additionally, as... Figure 6 and Figure 16 As shown, the water outlet pipe 4224 of the second pump body 422 is located completely below the tank body 421, making full use of the space between the tank body 421 and the filter element assembly 3 to accommodate the water outlet pipe 4224, avoiding the water outlet pipe 4224 from extending to the radial outside of the tank body 421 and interfering with the layout of other components.

[0337] In one implementation, such as Figure 14 As shown, the tank body 421 is provided with a heat insulation structure 4214, which surrounds the water storage cavity 4213 in a circumferential manner to reduce the cooling rate of the hot water in the tank body 421.

[0338] Furthermore, the tank body 421 has a double-layer vacuum structure, which constitutes the insulation structure 4214. Specifically, as... Figure 14 As shown, the insulation structure 4214 includes an outer tank 42141 and an inner tank 42142. The outer tank 42141 and the inner tank 42142 form a vacuum cavity 42143. The outer tank 42141, the vacuum cavity 42143 and the inner tank 42142 work together to achieve the function of heat preservation.

[0339] In one embodiment, a liquid level detection mechanism 4215 is provided inside the tank 421 to obtain liquid level information of the water storage chamber 4213.

[0340] Furthermore, such as Figure 14 As shown, the liquid level detection mechanism 4215 includes an upper float 42151, a lower float 42152, and a liquid level sensor (not shown in the figure). Both the upper float 42151 and the lower float 42152 are located inside the water storage chamber 4213. The upper float 42151 can float up and down between a first position and a second position, and the lower float 42152 can float up and down between a third position and a fourth position. When the water level in the water storage chamber 4213 changes, the liquid level sensor obtains the position information of the upper float 42151 and the lower float 42152 in the vertical direction to obtain the liquid level information of the water storage chamber 4213, so as to accurately control the amount of hot water stored in the water storage chamber 4213.

[0341] Furthermore, such as Figure 14 As shown, a mounting post 4216 is provided inside the tank body 421. The mounting post 4216 is parallel to the axis of the tank body 421. The upper float 42151 and the lower float 42152 are movably mounted on the mounting post 4216. The outer periphery of the mounting post 4216 has four limiting members 4217, which are respectively set in a first position, a second position, a third position, and a fourth position. Two of the limiting members 4217 are used to limit the upper float 42151 to float up and down only between the first position and the second position, and the other two limiting members 4217 are used to limit the lower float 42152 to float up and down only between the third position and the fourth position.

[0342] Furthermore, the mounting column 4216 has a hollow section (not shown in the figure), and the liquid level sensor is mounted in the hollow section.

[0343] In one implementation, such as Figure 14 As shown, a temperature sensor 4218 is provided inside the tank 421 to obtain water temperature information in the water storage chamber 4213, so as to adjust the water temperature in the tank 421 in a timely manner so that the hot water always maintains a preset temperature value. The preset temperature value can be a specific value (e.g., 85℃) or a range value (e.g., 82-88℃).

[0344] In one implementation, such as Figure 29 and Figure 30 As shown, the water purifier 1000 also includes a water distributor 900 for distributing water to the outside. Figure 18 As shown, the main unit 100 includes a water circuit assembly 1, which includes a hot water supply circuit 12 and a return circuit 13. The two ends of the hot water supply circuit 12 are connected to a purified water distributor 900 and a hot water container 42, respectively. The two ends of the return circuit 13 are also connected to the purified water distributor 900 and the hot water container 42, respectively. Hot water in the hot water container 42 flows into the purified water distributor 900 through the hot water supply circuit 12 and is distributed by the distributor. When the return circuit 13 is open, at least a portion of the water remaining in the purified water distributor 900 flows back to the hot water container 42 through the return circuit 13, reducing the residual water content in the purified water distributor 900. Of course, the water returning through the return circuit 13 is not limited to returning to the hot water container 42; it can also flow back to other containers (such as a separately configured return container) or back to the wastewater pipe.

[0345] By adopting the above technical solution, and by adding a return water path 13 between the water purifier 900 and the hot water container 42, when the return water path 13 is opened, at least a portion of the water remaining in the water purifier 900 will flow back into the tank 421 of the hot water container 42 through the return water path 13. This reduces the amount of residual water in the water purifier 900, thereby reducing the waiting time for hot water and the amount of cold water dispensed the next time hot water is dispensed, improving the accuracy of the water temperature, enhancing the customer experience, and reducing water waste. Furthermore, the hot water undergoes high-temperature sterilization during the return process, resulting in healthier drinking water.

[0346] In one embodiment, the water distributor 900 is located outside the main unit 100, and the water distributor 900 is connected to the main unit 100 via a connecting pipe.

[0347] In another embodiment, the water dispenser 900 can also be mostly located inside the main unit 100, with the water outlet of its dispensing port 923 located outside the main unit 100.

[0348] In one implementation, such as Figure 18 As shown, the water circuit assembly 1 includes a first valve 141, which is located on the return water circuit 13. When the first valve 141 is closed, the return water circuit 13 is blocked. When the first valve 141 is open, the return water circuit 13 is opened. At this time, if there is residual hot water in the water purifier 900, at least some of the residual water in the water purifier 900 can flow back to the hot water container 42 through the return water circuit 13 because the return water circuit 13 is open.

[0349] In one implementation, such as Figure 18As shown, the hot water container 42 includes a tank 421 and a second pump body 422. The second pump body 422 is located on the hot water supply line 12 and is used to pump water out of the tank 421 of the hot water container 42. Specifically, as shown... Figure 15 and Figure 18 As shown, the second outlet 4221 of the second pump body 422 is connected to the inlet of the hot water supply channel 12. The second pump body 422 first pumps the water in the tank 421 into the pump chamber 4222, and then pumps it into the hot water supply channel 12 through the second outlet 4221, and drives the hot water to flow forward in the hot water supply channel 12.

[0350] In one implementation, such as Figures 18 to 20 As shown, the water dispenser 900 includes a liquid buffer chamber 91 and a dispensing head 92 that are connected to each other. The liquid buffer chamber 91 is used to temporarily store liquid. The hot water supply line 12 is connected to the liquid buffer chamber 91, and the hot water from the hot water supply line 12 flows into the dispensing head 92 through the liquid buffer chamber 91.

[0351] Furthermore, such as Figures 18 to 20 As shown, the return water path 13 and the liquid buffer chamber 91 are connected before the water is distributed by the water purifier distributor 900. When the return water path 13 is opened, the hot water container 42, the hot water supply path 12, the liquid buffer chamber 91 and the return water path 13 are connected in sequence to form a preheating circulation water path. Under the power provided by the second pump body 422, a preheated hot water circulation is formed in the preheating circulation water path, so that the residual water in the liquid buffer chamber 91 flows back to the hot water container 42 through the return water path 13. In addition, the hot water supply path 12 and the liquid buffer chamber 91 are filled with hot water. In this way, the user can get hot water immediately when the water dispensing switch 921 is triggered, reducing the hot water waiting time.

[0352] In one embodiment, when the opening condition of the return water passage 13 is met, the return water passage 13 opens, and water in the liquid buffer chamber 91 flows back to the hot water container 42 through the return water passage 13. When the closing condition of the return water passage 13 is met, the return water passage 13 is blocked. The opening condition includes: the start of preheating water circulation; the closing condition includes: the end of preheating water circulation. Through preheating water circulation, residual water in the liquid buffer chamber 91 flows back to the hot water container 42 through the return water passage 13.

[0353] In one embodiment, when the water dispenser 900 dispenses water, the return water path 13 is blocked to avoid interfering with the user's water intake. When the water dispenser 900 stops dispensing hot water, the return water path 13 opens, and the water in the liquid buffer chamber 91 flows back to the hot water container 42 through the return water path 13 to reduce the amount of water remaining in the water dispenser 900. It should be understood that when the dispensing head 92 is directly connected to the liquid buffer chamber 91, if a small amount of water needs to be left at the dispensing port 923 of the water dispenser 900 to form a liquid seal after each water intake, then the water dispenser 900 retains liquid seal water, and the remaining water flows back to the tank 421 of the hot water container 42 through the return water path 13. The content of liquid seal water has a negligible impact on the water temperature when hot water is taken out. If, after each water dispensing cycle, the dispensing port 923 of the water purifier 900 is isolated from outside air by other means, or if the dispensing port 923 is not isolated from outside air, then all remaining water in the water purifier 900 can flow back to the tank 421 of the hot water container 42 through the return water path 13, achieving the effect of zero waiting time, zero stagnant water, and zero cold water when dispensing hot water. Furthermore, if... Figures 18 to 20 As shown, the liquid buffer chamber 91, the return water path 13, and the hot water container 42 are arranged sequentially from top to bottom, with a height difference between them. This height difference allows water in the liquid buffer chamber 91 to flow back to the hot water container 42 through the return water path 13, resulting in a simple return structure. Of course, the structure providing the return power for the return water path 13 is not limited to this; a small-power pump can also be installed on the return water path 13 to provide the return power.

[0354] In one implementation, such as Figure 29 As shown, the distribution head 92 includes a trigger element and a water intake switch 921. When the trigger element is activated and the water intake switch 921 is in the off state, the second pump body 422 operates to start the preheated water circulation.

[0355] Furthermore, such as Figure 30 As shown, the distribution head 92 includes a temperature selection operation element 922, which constitutes a trigger element. When water needs to be dispensed, the user first operates the temperature selection operation element 922 to select the water temperature. At the instant the temperature selection operation element 922 is operated, the second pump body 422 starts, and the preheating hot water circulation is initiated.

[0356] Furthermore, the preheating hot water circulation is configured such that when the preheating hot water circulation is executed for 3-5 seconds or one cycle, the temperature of the hot water in the hot water supply circuit 12 reaches the preset temperature value. The user operation of the temperature selection device 922 typically takes 3-5 seconds. Once the user selects the water temperature, the temperature of the hot water in the hot water supply circuit 12 has reached the preset temperature value, and the user can immediately operate the water dispensing switch 921 to dispense water, resulting in rapid hot water supply.

[0357] In one embodiment, the temperature selection operation element 922 and the water dispensing switch 921 may be in the form of, but are not limited to, touch buttons, mechanical buttons, or knobs.

[0358] In one embodiment, the upper surface of the dispensing head 92 is a touch screen, which includes indicator lights (not shown). These indicator lights can be used to indicate the positions of the temperature selection mechanism 922 and the water dispensing switch 921, as well as other information (such as indicating the water dispensing wait time). When the touch screen is in its initial state, the indicator lights are half-lit to allow the user to see the positions of the temperature selection mechanism 922 and the water dispensing switch 921. When the touch screen is touched, the indicator lights are fully lit to more clearly present the information.

[0359] In one implementation, such as Figure 20 and Figure 22 As shown, the liquid buffer chamber 91 includes a first connecting port 911, a second connecting port 912, and a third connecting port 913, with the first connecting port 911 and the second connecting port 912 located below the third connecting port 913. Figures 18 to 22 As shown, the hot water supply path 12 is connected to the first connection port 911, and the return path 13 is connected to the second connection port 912; one end of the distribution head 92 is provided with a distribution port 923, and the other end of the distribution head 92 is connected to the third connection port 913. When a preheating hot water circulation is formed in the preheating circulation path formed by the hot water container 42, the hot water supply path 12, the liquid buffer chamber 91, and the return path 13 connected in sequence, the hot water in the hot water container 42 is transported to the liquid buffer chamber 91 through the hot water supply path 12 and the first connection port 911. Since the first connection port 911 and the second connection port 912 are located below the third connection port 913, the hot water in the liquid buffer chamber 91 flows into the return path 13 through the second connection port 912, and will not or will not easily flow upward out of the third connection port 913.

[0360] In one embodiment, the heating element 6 is disposed on the hot water supply channel 12, and the second pump body 422 is located on the water channel between the hot water container 42 and the heating element 6. The heating element 6 is used to heat the water flow in the hot water supply channel 12.

[0361] Furthermore, such as Figure 18 As shown, the hot water supply circuit 12 includes a first hot water pipe 121 and a second hot water pipe 122. The outlet end of the first hot water pipe 121 is connected to the liquid buffer chamber 91, the inlet end of the second hot water pipe 122 is connected to the hot water container 42, and the outlet end of the second hot water pipe 122 is connected to the heating element 6. That is, when the hot water container 42 supplies hot water to the water purifier distributor 900, the hot water container 42, the second hot water pipe 122, the heating element 6, the first hot water pipe 121, and the liquid buffer chamber 91 are connected in sequence along the water flow direction.

[0362] The water circuit assembly 1 includes a second water circuit 15 and a second valve 142. The outlet of the second water circuit 15 is connected to the hot water container 42. The first outlet of the second valve 142 is connected to the inlet of the first hot water pipe 121. The second outlet of the second valve 142 is connected to the second water circuit 15. The inlet of the second valve 142 is connected to the heating element 6. When the water temperature in the hot water container 42 has not reached the preset value and the water purifier 1000 is not turned on to dispense water, the first outlet of the second valve 142 is closed and the second outlet is open. The heating element 6 and the second pump body 422 are turned on. The water in the hot water container 42 enters the heating element 6 through the second hot water pipe 122. After being heated by the heating element 6, the water circulates back into the hot water container 42 through the second water circuit 15, forming a heating circulation water circuit so that the water temperature in the hot water container 42 reaches the preset value. If the user needs to take water, the first outlet of the second valve 142 is in the open state and the second outlet of the second valve 142 is in the closed state. The water in the hot water container 42 passes through the second hot water pipe 122, the heating element 6 and the first hot water pipe 121 in sequence and enters the liquid buffer chamber 91, and is distributed by the distributor 92.

[0363] In one implementation, such as Figure 18 As shown, the filter element assembly 3 is located on the first water passage 11, and the outlet of the first water passage 11 is connected to the water purifier distributor 900 to supply purified room temperature water, which users can drink directly. The room temperature water temperature is related to the current ambient temperature and is not limited to a specific value.

[0364] Furthermore, such as Figure 18 and Figure 22 As shown, the outlet of the first water path 11 is connected to the fourth connection port 914 of the liquid buffer chamber 91, and the first water path 11 is used to supply room temperature water into the liquid buffer chamber 91. The preset temperature value in the hot water container 42 is set to T1, the temperature of the room temperature water supplied by the first water path 11 is T2, and the target temperature for water intake is T. m The preset temperature T1 inside the hot water container 42 is 82-88℃, preferably 85℃, which can prevent repeatedly boiled water from appearing inside the hot water container 42.

[0365] Water intake includes the following four modes:

[0366] (1) When T m =T1, when the user’s water target is the second level of hot water (e.g., 85℃ water), the hot water in the hot water container 42 can be used directly. The water in the hot water container 42 flows into the distribution head 92 through the hot water supply channel 12 and the liquid buffer chamber 91, and is distributed to the user through the distribution head 92.

[0367] (2) When T m=T2, the user's water target is room temperature water, the room temperature water in the first water channel 11 can be used directly, the water in the first water channel 11 flows into the distribution head 92 through the liquid buffer chamber 91, and is distributed to the user through the distribution head 92.

[0368] (3) When T2 < T m When the temperature is less than T1, the user's target water temperature is the first level of hot water (e.g., 45℃). This water temperature is between the water temperature in the hot water container 42 and the ambient water temperature. The hot water flow in the hot water container 42 and the ambient water flow in the first water path 11 mix in the liquid buffer chamber 91. By controlling the mixing amount of ambient water and hot water, the desired water temperature (e.g., 45℃) is achieved. That is, the temperature obtained by mixing is T. m The water then flows into the distributor 92 and is distributed to the user via the distributor 92.

[0369] (4) When T m When the temperature is greater than T1, the user's target water temperature is the third level of hot water (e.g., 95℃). The water temperature exceeds the hot water temperature in the hot water container 42. The water in the hot water container 42 is heated to the required temperature by the heating element 6 and then flows into the distribution head 92 through the liquid buffer chamber 91 and is distributed to the user through the distribution head 92.

[0370] In this solution, the water purifier 1000 can provide drinking water in four temperature ranges, from low to high: room temperature water, first-level hot water (39-46℃), second-level hot water (82-88℃), and third-level hot water (97-99℃). The first-level hot water can be used for making milk or for direct drinking. The second-level hot water can be used for brewing, including but not limited to green tea or flower tea. The third-level hot water can be used for brewing, including but not limited to black tea or white tea. When the third-level hot water (97-99℃) is needed, it is supplied by heating the second-level hot water (82-88℃) through the heating element 6. The heating speed is fast, and the high-temperature water is obtained quickly.

[0371] In one implementation, such as Figure 18 As shown, a first check valve 171 is provided at the connection between the outlet of the first water passage 11 and the liquid buffer chamber 91. The first check valve 171 is used to prevent water from flowing into the first water passage 11 from the liquid buffer chamber 91.

[0372] In one implementation, such as Figure 18As shown, the inlet of the water purification container 41 is connected to the first water passage 11, and the outlet of the water purification container 41 is connected to the hot water supply passage 12 through the third water passage 16. A third pump body 22 is provided on the third water passage 16. When the liquid level in the water purification container 41 is lower than the preset purified water level value and the water purifier is not turned on to dispense water, the first pump body 21 operates, so that the water in the first water passage 11 flows into the water purification container 41 after being purified by the filter element assembly 3, in order to replenish the purified water. When the liquid level in the hot water container 42 is lower than the preset hot water level value and the water purifier is not turned on to dispense water, the third pump body 22 operates, so that the water in the water purification container 41 flows into the hot water supply passage 12, and after being heated by the heating element 6, flows into the hot water container 42 through the second water passage 15, in order to replenish the hot water.

[0373] Furthermore, such as Figure 18 As shown, the third water passage 16 is connected to the hot water supply passage 12 via the third valve 143. Specifically, the third valve 143 is a three-way valve. The outlet of the third valve 143 is connected to the heating element 6, the first inlet of the third valve 143 is connected to the second hot water pipe 122, and the second inlet of the third valve 143 is connected to the third water passage 16. Under normal circumstances, when the user draws water, the first inlet of the third valve 143 is open and the second inlet is closed, and hot water is supplied to the water purifier distributor 900 from the hot water container 42. When the user draws hot water, if there is no hot water in the hot water container 42 or the hot water storage is insufficient, the first inlet of the third valve 143 will close and the second inlet will open. The water in the water purifier container 41, under the power provided by the third pump body 22, flows into the heating element 6 through the third water passage 16, and is directly supplied to the water purifier distributor 900 after being heated by the heating element 6.

[0374] In one embodiment, the third pump body 22 is a diaphragm pump.

[0375] In one implementation, such as Figure 18 and Figure 19 As shown, the hot water container 42 is provided with a first exhaust pipe 427, and the outlet of the first exhaust pipe 427 is connected to the second exhaust pipe 93 provided with the water purification distributor 900 to ensure the pressure balance of the hot water container 42.

[0376] Furthermore, such as Figure 18 As shown, the water purification container 41 is provided with a third exhaust pipe 412, and the outlet of the third exhaust pipe 412 is connected to the first exhaust pipe 427 to ensure the pressure balance of the water purification container 41.

[0377] In one embodiment, the hot water supply circuit 12 is made of Teflon tubing, which has good thermal insulation properties.

[0378] In one implementation, such as Figure 18As shown, the filter assembly 3 includes a first filter element 31, a second filter element 32, and a third filter element 33 arranged sequentially along the water flow direction of the first water passage 11. The first filter element 31 and the second filter element 32 are used to filter and purify the water flow, and the third filter element 33 is used to inhibit microorganisms and / or improve the taste. The water passage assembly 1 includes a first wastewater passage 181, the inlet of which is connected to the water passage between the second filter element 32 and the third filter element 33. The first wastewater passage 181 is used to discharge wastewater discharged from the second filter element 32.

[0379] Furthermore, such as Figure 18 As shown, the water circuit assembly 1 includes a second wastewater circuit 182. The inlet of the second wastewater circuit 182 is connected to the downstream of the third filter element 33. When the filter element assembly 3 needs cleaning, water enters the first water circuit 11 and passes through the first filter element 31, the second filter element 32, and the third filter element 33 in sequence to clean the three filter elements. The cleaned wastewater is discharged through the second wastewater circuit 182. A second check valve 172 is provided on the second wastewater circuit 182 to prevent backflow of external wastewater through the second wastewater circuit 182.

[0380] In one implementation, such as Figure 19 As shown, the water distributor 900 includes a distribution port 923, a water outlet channel 924, and a first water-blocking structure 925. The distribution port 923 is used to dissipate water. The two ends of the water outlet channel 924 are respectively connected to the distribution port 923 and the water supply port of the water circuit assembly 1 of the main unit 100. The water outlet channel 924 includes a first bottom wall 9241 and a second bottom wall 9242. The first water-blocking structure 925 is disposed on the bottom wall of the water outlet channel 924. The second bottom wall 9242, the first water-blocking structure 925, and the first bottom wall 9241 are distributed sequentially along the water flow direction. The first bottom wall 9241 slopes downward in the direction towards the distribution port 923, and the second bottom wall 9242 slopes downward in the direction away from the distribution port 923.

[0381] By adopting the above technical solution, a first water-blocking structure 925 is set on the bottom wall of the water outlet channel 924, so that a small amount of water can remain in the water outlet channel 924 after each water dispensing to form a liquid seal. Outside air cannot pass through the liquid seal and penetrate into the water purifier distributor 900, thus preventing the growth of bacteria and ensuring drinking water health. At the same time, by configuring the first bottom wall 9241 to slope downwards towards the distribution port 923, smooth water dispensing is ensured. By configuring the second bottom wall 9242 to slope downwards away from the distribution port 923, water in the channel on the side of the first water-blocking structure 925 away from the distribution port 923 can flow back after each water dispensing, reducing the accumulation of stagnant water in the water outlet channel 924. This reduces the waiting time for the next hot water dispensing and improves the accuracy of the hot water temperature. In addition, the first water-blocking structure 925 and the first bottom wall 9241 also play a role in water vapor separation, preventing water splashing due to the presence of water vapor during the water dispensing process from the distribution port 923.

[0382] In one implementation, such as Figure 19 As shown, the second bottom wall 9242, the first water-blocking structure 925, and the first bottom wall 9241 are connected in sequence. Taking the first water-blocking structure 925 as the boundary, the side of the first water-blocking structure 925 facing the distribution port 923 can smoothly discharge water. That is, when water is taken, after the water flow in the water outlet channel 924 passes the first water-blocking structure 925, it immediately flows towards the distribution port 923 under the guidance of the first bottom wall 9241. The side of the first water-blocking structure 925 away from the distribution port 923 can promote backflow. That is, after water is taken, the water flow on the side of the first water-blocking structure 925 away from the distribution port 923 immediately flows back under the guidance of the second bottom wall 9242.

[0383] Furthermore, such as Figure 19 As shown, the second bottom wall 9242 is higher than the first bottom wall 9241, which facilitates the water flow to quickly pass over the first water-blocking structure 925 during the water intake process.

[0384] In one implementation, such as Figure 19 As shown, the bottom wall of the water outlet channel 924 protrudes upward to form the first water-blocking structure 925, which is easy to process.

[0385] In one implementation, such as Figure 19 and Figure 21As shown, the water distributor 900 includes an air-blocking structure 926 and a second water-blocking structure 92311. The air-blocking structure 926 is located on the top wall of the water outlet channel 924, between the distribution port 923 and the first water-blocking structure 925. The second water-blocking structure 92311 is located at the distribution port 923. The height h1 of the top wall of the first water-blocking structure 925 is higher than the height h2 of the bottom wall of the air-blocking structure 926. h1 is configured to partially block the backflow of water in the water outlet channel 924, so as to form a pre-stored water level h3 between the first water-blocking structure 925 and the second water-blocking structure 92311. Furthermore, h2 < h3 < h1, so that the pre-stored water forms a water seal at the air-blocking structure 926, thereby preventing the exchange of gas on both sides of the air-blocking structure 926, thus isolating air and preventing the growth of bacteria.

[0386] It should be understood that if the structure of the distribution port 923 located at one end of the water outlet channel 924 is configured such that the small amount of water retained by the first water-blocking structure 925 can directly cover the port of the distribution port 923, that is, the reserved water directly seals the distribution port 923, then there is no need to set up the air-blocking structure 926.

[0387] Furthermore, such as Figure 19 and Figure 21 As shown, the outer wall of the distribution port 923 forms the second water-blocking structure 92311, eliminating the need for a separate component as the second water-blocking structure 92311, which helps reduce the number of components.

[0388] In one implementation, such as Figure 19 As shown, the top wall of the water outlet channel 924 protrudes downward to form an air-blocking structure 926, which is easy to process.

[0389] In one implementation, such as Figures 19 to 21As shown, the water outlet channel 924 includes a horizontal channel 9243 and a vertical channel 9244 that are connected. The distribution port 923 is connected to the horizontal channel 9243, and the liquid buffer chamber 91 is connected to the vertical channel 9244. The first water-blocking structure 925 is located within the horizontal channel 9243. The water dispenser 900 includes a thermostat 94. The detection end of the thermostat 94 is located within the vertical channel 9244, and the lowest point D2 of the detection end is located above the liquid buffer chamber 91 and below the top wall of the first water-blocking structure 925. During the preheating circulation process, the hot water in the hot water container 42 is transported to the liquid buffer chamber 91 through the hot water supply channel 12 and the first connection port 911. The hot water in the liquid buffer chamber 91 flows into the return channel 13 through the second connection port 912. When the thermostat 94 obtains temperature information, it indicates that there is a risk of the hot water in the liquid buffer chamber 91 overflowing from the third connection port 913 of the liquid buffer chamber 91 or that overflow has already occurred. Then, the second pump body 422 is turned off, the preheating circulation is stopped, and the water in the liquid buffer chamber 91 flows back to the hot water container 42 through the return channel 13.

[0390] In addition, the thermostat 94 is also used to detect the water temperature during normal water intake. If the temperature detected by the thermostat 94 does not reach the preset value, the water temperature can be adjusted by adjusting the water flow rate or the mixing ratio of room temperature water and hot water, so as to provide drinking water with the required temperature.

[0391] Furthermore, in one embodiment, when the preheating water circulation stops and the thermostat 94 does not obtain temperature information, it indicates that the overflow risk has been eliminated, and the second pump 422 is turned on to restore the preheating water circulation.

[0392] In another embodiment, when the preheated water circulation stops for a preset period of time, it indicates that the risk of overflow has been eliminated, and the second pump 422 is turned on to resume the preheated water circulation.

[0393] In one implementation, such as Figure 19 As shown, the water distributor 900 includes an ultraviolet (UV) sterilization element 95, which is located within the water outlet channel 924 and near the distribution port 923. The UV sterilization element 95 sterilizes the liquid-sealed water within the water outlet channel 924, ensuring the hygiene of the interior of the water distributor 900. Furthermore, the UV sterilization element 95 is located between the distribution port 923 and the first water-blocking structure 925, and is positioned close to the distribution port 923.

[0394] In one implementation, such as Figure 19 As shown, the dispensing head 92 is roughly L-shaped to form a horizontal channel 9243 and a vertical channel 9244. (As...) Figure 20As shown, the end of the dispensing head 92 away from the dispensing port 923 is provided with a second mounting part 927; the second mounting part 927 is inserted into the fourth communication port 914 of the liquid buffer chamber 91, and a third sealing member 96 is provided at the assembly point of the two.

[0395] In one implementation, such as Figure 20 and Figure 22 As shown, the water distributor 900 includes a water return structure 97. The water return structure 97 has a hollow structure to form a liquid buffer chamber 91. Setting the water distributor 900 as a multi-part assembly structure can reduce the complexity of individual parts and avoid making the parts structure too complex, which would lead to complicated processing molds and increased processing costs.

[0396] In one implementation, such as Figure 19 , Figure 21 and Figure 23 As shown, the distribution port 923 includes a first distribution pipe 9231, a second distribution pipe 9232, and a plug 9233. The height h4 of the first distribution pipe 9231 is higher than the height of the first water-blocking structure 925. The first distribution pipe 9231 has a first water distribution inlet 92312. The height h5 of the second distribution pipe 9232 is higher than the h4 of the first distribution pipe 9231. The outer wall of the first distribution pipe 9231 forms the second water-blocking structure 92311. The plug 9233 is inserted into part of the inlet of the second distribution pipe 9232. The assembly point of the plug 9233 and the second distribution pipe 9232 forms a steam venting gap 9234. The plug 9233 divides the inlet of the second distribution pipe 9232 into a second water distribution inlet 92321 and a steam venting gap 9234.

[0397] In this scheme, the water outlet of distribution port 923 includes the following two scenarios:

[0398] (1) The water level in the water outlet channel 924 is h6. When h4<h6≤h5, the water in the water outlet channel 924 enters the distribution port 923 through the first water distribution inlet 92312. In addition, the water vapor in the water outlet channel 924 enters the distribution port 923 through the second water distribution inlet 92321 and is discharged outward.

[0399] (2) When h6 > h5, the water in the outlet channel 924 enters the distribution port 923 through the first water distribution inlet 92312 and the second water distribution inlet 92321. Furthermore, the water vapor in the outlet channel 924 enters the distribution port 923 through the steam exhaust gap 9234 and is then discharged outwards. It should be understood that when the water flow rate is too large or too rapid, some water may enter the distribution port 923 through the steam exhaust gap 9234, but the main function of the steam exhaust gap 9234 is to discharge the water vapor from the outlet channel 924.

[0400] In one implementation, such as Figure 19As shown, the first distribution pipe 9231 is located between the second distribution pipe 9232 and the first water-blocking structure 925. Thus, when h4 < h6 ≤ h5, the water in the outlet channel 924 can first contact the first distribution pipe 9231 and enter the distribution port 923 through the first water distribution inlet 92312.

[0401] In one implementation, such as Figure 21 As shown, the distribution port 923 includes an outlet channel 9235. The outlets of the first distribution pipe 9231 and the second distribution pipe 9232 are respectively connected to the outlet channel 9235, and the purified water is distributed to the outside through the outlet channel 9235.

[0402] In one implementation, such as Figure 19 As shown, the water purifier distributor 900 includes a second exhaust pipe 93, which is located inside the distributor head 92 of the water purifier distributor 900. The outlet 931 of the second exhaust pipe 93 faces downward and is connected to the atmosphere. The first exhaust pipe 427 of the hot water container 42 is connected to the inlet of the second exhaust pipe 93 to ensure the air pressure balance inside the hot water container 42.

[0403] In one implementation, such as Figure 30 As shown, the temperature selection operation 922 of the dispensing head 92 is a touch key, and the water dispensing switch 921 is a knob structure and a pressable structure, located above the touch screen. When the user wants to dispense water, they select the water temperature by touching the corresponding temperature selection operation 922, and then press the water dispensing switch 921 to start dispensing water; or, they select the temperature by rotating the water dispensing switch 921, and then press the water dispensing switch 921 to start dispensing water. Of course, the structure of the user temperature selection operation 922 and the water dispensing switch 921 is not limited to this; any form of selection operation and switch structure can be applied to this solution.

[0404] In one implementation, such as Figure 19 and Figure 23 As shown, the dispensing head 92 includes an inner core body 928 and an inner core cover 929. The inner core body 928 has a groove structure 9281, and the inner core cover 929 is used to seal the groove structure 9281. The inner core body 928 and the inner core cover 929 together form a water outlet channel 924. The first water-blocking structure 925, the air-blocking structure 926, and the dispensing port 923 are all integrally formed on the inner core body 928. The inner core cover 929 has a first mounting seat 9291 and a second mounting seat 9292. The ultraviolet sterilization element 95 is inserted into the first mounting seat 9291, and its ultraviolet emitting end is located in the water outlet channel 924. The temperature controller 94 is screwed into the second mounting seat 9292, and its detection end is located in the water outlet channel 924.

[0405] In one implementation, such as Figures 24 to 28As shown, the integrated water circuit component 7 includes multiple water inlets and multiple flow channels. The multiple water inlets include a raw water inlet 721, a first filter element inlet 7221, a first filter element outlet 7222, a first pump body inlet 7231, a first pump body outlet 7232, a second filter element inlet 7241, a second filter element outlet 7242, a second filter element wastewater outlet 7243, a third filter element inlet 7251, a third filter element outlet 7252, a first purified water outlet 7261, a second purified water outlet 7262, and a wastewater outlet 727. Multiple flow channels include a first flow channel 731 connecting the raw water inlet 721 and the first filter element inlet 7221, a second flow channel 732 connecting the first filter element outlet 7222 and the first pump body inlet 7231, a third flow channel 733 connecting the first pump body outlet 7232 and the second filter element inlet 7241, a fourth flow channel 734 connecting the second filter element outlet 7242 and the third filter element inlet 7251, a fifth flow channel 735 connecting the third filter element outlet 7252 and the first purified water outlet 7261, a sixth flow channel 736 connecting the third filter element outlet 7252 and the second purified water outlet 7262, a seventh flow channel 737 connecting the second filter element wastewater outlet 7243 and the wastewater outlet 727, and an eighth flow channel 738 connecting the third filter element outlet 7252 and the wastewater outlet 727. Among them, the raw water inlet 721 is connected to the first water channel 11 inside the main unit 100, which is used to connect to the water source; the first purified water outlet 7261 is connected to the purified water distributor 900 of the water purifier; and the second purified water outlet 7262 is connected to the purified water container 41.

[0406] Furthermore, such as Figure 26 and Figure 27 As shown, the raw water inlet 721, the first purified water outlet 7261, the second purified water outlet 7262, and the wastewater outlet 727 are located on the upper part of the integrated water circuit component 7, so as to lay as many corresponding water pipes as possible inside the main unit 100 in the upper position inside the casing 5, making full use of the narrow space between the top wall of other components and the casing 5 to lay water pipes.

[0407] Furthermore, such as Figure 24 , Figure 26 and Figure 27 As shown, the raw water inlet 721, wastewater outlet 727, second purified water outlet 7262, and first purified water outlet 7261 are arranged sequentially along the width direction (i.e., the second direction b) of the integrated water circuit component 7. Since the filter element assembly 3 is located downstream of the raw water inlet 721 and upstream of the second purified water outlet 7262 and the first purified water outlet 7261, arranging the positions of the raw water inlet 721, wastewater outlet 727, second purified water outlet 7262, and first purified water outlet 7261 according to the position of the filter element assembly 3 in the water circuit is beneficial to shortening the length of the water circuit pipeline.

[0408] In one implementation, such as Figure 24As shown, the top wall of the integrated water circuit component 7 is provided with an installation pipe 78, which is connected to the original water inlet 721. The installation pipe 78 is used to install a low-pressure switch (not shown in the figure), which is used to detect whether the water source is interrupted.

[0409] In one implementation, such as 24 and Figure 25 As shown, the first filter element inlet 7221 and the first filter element outlet 7222 are respectively connected to the second matching valve of the first filter element 31 through the corresponding first matching valve 79. The second filter element inlet 7241, the second filter element outlet 7242 and the second filter element wastewater outlet 7243 are respectively connected to the second matching valve of the second filter element 32 through the corresponding first matching valve 79. The third filter element inlet 7251 and the third filter element outlet 7252 are respectively connected to the second matching valve of the third filter element 33 through the corresponding first matching valve 79. Since the filter element assembly 3 is located at the lower part inside the housing 5, and the second filter element 32 is located above the first filter element 31 and the third filter element 33, the first filter element inlet 7221, the first filter element outlet 7222, the third filter element inlet 7251 and the third filter element outlet 7252 are arranged at the lower part of the integrated water circuit component 7, and the second filter element inlet 7241, the second filter element outlet 7242 and the second filter element wastewater outlet 7243 are located in the middle of the integrated water circuit component 7, so as to facilitate the connection between the matching first matching valve and the second matching valve of the filter element.

[0410] Furthermore, such as Figure 25 As shown, the first filter element inlet 7221, the first filter element outlet 7222, the third filter element inlet 7251, and the third filter element outlet 7252 are arranged sequentially along the width direction of the integrated water circuit component 7, and the second filter element inlet 7241, the second filter element outlet 7242, and the second filter element wastewater outlet 7243 are arranged sequentially along the width direction of the integrated water circuit component 7 to match the position of the corresponding filter elements.

[0411] In one implementation, such as Figure 25 As shown, since the raw water inlet 721 and the first flow channel 731 are the upstream of the entire waterway within the main unit 100, the first flow channel 731 is set close to the vertical side wall of the integrated waterway component 7. The first flow channel 731 and the second flow channel 732 both extend vertically and are set adjacent to each other, which is conducive to the compact design of each flow channel.

[0412] Furthermore, such as Figure 25 As shown, the third flow channel 733 is U-shaped and the fourth flow channel 734 is L-shaped. The third flow channel 733 surrounds the fourth flow channel 734. The first flow channel 731, the second flow channel 732 and the third flow channel 733 are arranged sequentially along the width direction of the integrated water channel component 7, which is conducive to the compact design of each flow channel.

[0413] Furthermore, such as Figure 25As shown, the fifth flow channel 735 extends vertically, with one end of the fifth flow channel 735 inserted downward into the U-shaped area formed by the third flow channel 733 and this end being parallel to one end of the fourth flow channel 734. The other end of the fifth flow channel 735 extends upward, which further facilitates the compact design of each flow channel.

[0414] In one implementation, such as Figure 18 , Figure 25 and Figure 26 As shown, the fifth flow channel 735 is equipped with a first valve interface 741, which is used to install a fourth valve 144. The fourth valve 144 is used to control the opening and closing of the fifth flow channel 735. When the user takes room temperature water or the target water temperature is T... m When the water temperature is between the ambient water temperature T2 and the preset temperature T1 in the hot water container 42, the fourth valve 144 opens; otherwise, the fourth valve 144 closes.

[0415] In one implementation, such as Figure 25 As shown, the sixth flow channel 736 is located on one side above the fifth flow channel 735 and extends vertically, which is beneficial for the compact design of each flow channel. Figure 18 , Figure 25 and Figure 26 As shown, the integrated water circuit component 7 includes a second valve interface 742, which is used to install a fifth valve 145. The fifth valve 145 is used to control the opening and closing of the sixth flow channel 736. When the water level in the purified water container 41 does not reach the preset purified water level value, the fifth valve 145 opens, and the water purified by the filter element assembly 3 flows into the purified water container 41 through the sixth flow channel 736; when the water level in the purified water container 41 reaches the preset purified water level value, the fifth valve 145 is closed.

[0416] Furthermore, such as Figure 25 As shown, the seventh flow channel 737 extends vertically, and the seventh flow channel 737, the sixth flow channel 736 and the fifth flow channel 735 are arranged sequentially along the width direction of the integrated water channel component 7, which is conducive to the compact design of each flow channel.

[0417] Furthermore, the eighth flow channel 738 partially overlaps with the seventh flow channel 737. Specifically, the seventh flow channel 737 is used to transport the wastewater discharged from the second filter element 32, and the eighth flow channel 738 is used to transport the wastewater formed by cleaning the first filter element 31, the second filter element 32, and the third filter element 33. The two types of wastewater can eventually merge into the same wastewater pipe and be discharged to the outside. Therefore, configuring the eighth flow channel 738 to partially overlap with the seventh flow channel 737, and the wastewater in the eighth flow channel 738 flows to the wastewater outlet 727 through the seventh flow channel 737, is beneficial for the compact design of each flow channel.

[0418] In one implementation, such as Figure 18 , Figure 25 and Figure 26 As shown, the eighth flow channel 738 is provided with a third valve interface 743, which is used to install a sixth valve 146. The sixth valve 146 is used to control the opening and closing of the eighth flow channel 738. When the filter element assembly 3 does not need to be cleaned, the sixth valve 146 is closed; when the filter element assembly 3 needs to be cleaned, the sixth valve 146 is opened so that the wastewater after cleaning is discharged from the main unit 100 through the eighth flow channel 738.

[0419] In one implementation, such as Figure 18 , Figure 25 and Figure 26 As shown, the seventh flow channel 737 is provided with a fourth valve interface 744, which is used to install the seventh valve 147. The seventh valve 147 controls the opening and closing of the seventh flow channel 737. When the second filter element 32 does not need to discharge wastewater, the seventh valve 147 is closed; when the second filter element 32 needs to discharge wastewater, the seventh valve 147 is open.

[0420] In one implementation, such as Figure 18 , Figure 25 and Figure 26 As shown, a fifth valve interface 745 is provided on the first flow channel 731. The fifth valve interface 745 is used to install an eighth valve 148, which controls the opening and closing of the first flow channel 731. When the first water channel 11 of the water circuit assembly 1 needs water to enter, the eighth valve 148 opens; when the first water channel 11 does not need water to enter, the eighth valve 148 closes.

[0421] In one implementation, such as Figure 18 , Figure 25 and Figure 26 As shown, the integrated water circuit component 7 includes a check valve interface 746, which is used to install a second check valve 172. The second check valve 172 is used to prevent wastewater from flowing back into the eighth flow channel 738.

[0422] In one implementation, such as Figure 18 and Figure 28As shown, the integrated water circuit component 7 includes a first TDS sensor interface 751, an NTC sensor interface 752, a second TDS sensor interface 753, and a flow meter interface 754. The first TDS sensor interface 751 is connected to the second flow channel 732 and is used to mount a first TDS sensor 81, which is used to detect the water quality of the water flowing in the second flow channel 732. The NTC sensor interface 752 is connected to the fourth flow channel 734 and is used to mount an NTC sensor 82, which is used to detect the water temperature of the water flowing in the fourth flow channel 734. The second TDS sensor interface 753 is connected to the fourth flow channel 734 and is used to mount a second TDS sensor 83, which is used to detect the water quality of the water flowing in the fourth flow channel 734. The flow meter interface 754 is located downstream of the third filter cartridge outlet 7252. The flow meter interface 754 is used to install the flow meter 84, which is used to detect the flow rate of the water purified by the filter cartridge assembly 3.

[0423] In one embodiment, the cross-sectional area of ​​the flow channel is greater than or equal to 40 mm². 2 This facilitates the smooth flow of water.

[0424] In one implementation, such as Figure 24 As shown, the integrated water channel component 7 includes a first plate 76 and a second plate 77. The wall thickness of the first plate 76 and the second plate 77 is 4mm. The first plate 76 and the second plate 77 are welded by hot plate welding with a welding depth ≥4mm to ensure structural strength and withstand pressure of 3.2Mpa. The first plate 76 and the second plate 77 together form multiple flow channels. The integrated water channel component 7 is configured as a split structure, which facilitates the processing of the flow channel structure.

[0425] Furthermore, such as Figure 1 and Figure 24 As shown, the first plate 76 is located outside the second plate 77, and the first slot 71 is located on the side of the second plate 77 opposite to the first plate 76. One end of the first filter element 31, the second filter element 32, and the third filter element 33 are respectively engaged with the three first slots 71 on the second plate 77, as shown. Figure 25 As shown, the first filter element inlet 7221, the first filter element outlet 7222, the first pump body inlet 7231, the first pump body outlet 7232, the second filter element inlet 7241, the second filter element outlet 7242, the second filter element wastewater outlet 7243, the third filter element inlet 7251, and the third filter element outlet 7252 are all located on the second plate 77. Figure 26 and Figure 27 As shown, the raw water inlet 721, the first purified water outlet 7261, the second purified water outlet 7262, the wastewater outlet 727, and the installation pipe 78 are all located on the second plate 77.

[0426] In one implementation, such as Figure 25 and Figure 26 As shown, the bends in the flow channel are all rounded to prevent residual water stains from breeding bacteria.

[0427] Second Implementation Method

[0428] The following is based on Figures 31 to 34 This invention provides a detailed description of the second embodiment of the water purifier.

[0429] The water purifier in this embodiment has a similar structure to the water purifier in the first embodiment. The differences between the two embodiments are mainly described below.

[0430] In this embodiment, such as Figures 31 to 34 As shown, the water distributor 900 includes a mixing chamber 972 and two non-communicating liquid buffer chambers 91 and 971 at room temperature. The liquid buffer chamber 91 is lower than the mixing chamber 972. The outlet of the liquid buffer chamber 91 is connected to the mixing chamber 972, and the inlet of the liquid buffer chamber 91 is connected to the hot water supply circuit 12 and the return water circuit 13 of the main unit 100, respectively. The outlet of the room temperature water chamber 971 is connected to the mixing chamber 972, and the inlet of the room temperature water chamber 971 is connected to the outlet of the first water circuit 11 of the main unit 100.

[0431] When the water purifier distributor 900 distributes room temperature water, the water from the first water path 11 is purified and transported to the room temperature water chamber 971, then enters the mixing chamber 972, and is distributed to the outside through the distributor head 92 of the water purifier distributor 900.

[0432] When the water purifier distributor 900 needs to call hot water through the hot water supply circuit 12, the hot water in the hot water supply circuit 12 enters the mixing chamber 972 through the liquid buffer chamber 91, and is distributed to the outside through the distribution head 92 of the water purifier distributor 900.

[0433] When the return water path 13 is opened, the water in the liquid buffer chamber 91 enters the return water path 13 and flows back to the hot water container 42 of the host 100 via the return water path 13.

[0434] By adopting the above technical solution, the water distributor 900 is equipped with three water chambers: a mixing chamber 972, a liquid buffer chamber 91, and a room temperature water chamber 971. When hot water is dispensed, the hot water flows to the distributor head 92 through the liquid buffer chamber 91. When the return water path 13 is opened, the residual water in the liquid buffer chamber 91 will flow back to the tank 421 of the hot water container 42 through the return water path 13, thereby reducing the amount of residual water in the water distributor 900. This reduces the waiting time for hot water when dispensed again.

[0435] It should be understood that the outlet and inlet of the liquid buffer chamber 91, and the outlet and inlet of the room temperature water chamber 971 are based on the water flow direction when the water purifier distributor 900 is in normal water distribution state. For example, when the water purifier distributor 900 needs to call hot water through the hot water supply circuit 12, the hot water in the hot water supply circuit 12 flows into the liquid buffer chamber 91 from the inlet, and then the hot water in the liquid buffer chamber 91 flows into the mixing chamber 972 from the outlet of the liquid buffer chamber 91.

[0436] In one implementation, such as Figures 32 to 34 As shown, the water distributor 900 includes a return water structure 97, which is integrally formed with a mixing chamber 972, a liquid buffer chamber 91, and a room temperature water chamber 971. In this solution, by adding independent components (the return water structure) to form the mixing chamber 972, the liquid buffer chamber 91, and the room temperature water chamber 971, modifications to the water distributor 900 can be reduced, thereby lowering manufacturing costs.

[0437] In one implementation, such as Figure 20 , Figure 31 and Figure 34 As shown, the dispensing head 92, mixing chamber 972, liquid buffer chamber 91, return water path 13, and hot water container 42 are arranged sequentially from top to bottom. Utilizing the height difference, residual water in the dispensing head 92 can flow sequentially through the mixing chamber 972 and the liquid buffer chamber 91, and then return to the hot water container 42 through the return water path 13. The second mounting part 927 of the dispensing head 92 is connected to the outlet end of the mixing chamber 972, and a third sealing element 96 is provided at the assembly point of the two. It should be understood that the main difference between this embodiment and the first embodiment lies in the specific structure of the return water structure 97, while the assembly structure and positional relationship between the return water structure 97 and the dispensing head 92 are the same as in the first embodiment, and will not be described again here.

[0438] In one implementation, such as Figure 31 , Figure 32 and Figure 34 As shown, the liquid buffer chamber 91 is provided with a first connecting port 911, a second connecting port 912 and a third connecting port 913. The third connecting port 913 is located above the first connecting port 911 and the second connecting port 912. The ambient temperature water chamber 971 is provided with a fifth connecting port 9711 and a sixth connecting port 9712. The first connecting port 911 is connected to the hot water supply channel 12, the second connecting port 912 is connected to the return water channel 13, the third connecting port 913 and the sixth connecting port 9712 are respectively connected to the mixing chamber 972, and the fifth connecting port 9711 is connected to the first water channel 11.

[0439] In one implementation, such as Figure 31 and Figure 34As shown, a third check valve 173 is provided at the connection between the ambient temperature water chamber 971 and the first water passage 11. The third check valve 173 is used to prevent water in the water purifier 900 from entering the first water passage 11.

[0440] Furthermore, such as Figure 34 As shown, the third check valve 173 is located inside the inlet of the ambient temperature water chamber 971.

[0441] In one embodiment, before the water is dispensed by the water dispenser 900, such as Figure 31 and Figure 34 As shown, the return water path 13 is opened, and the hot water container 42, the hot water supply water path 12, the liquid buffer chamber 91 and the return water path 13 are connected in sequence to form a preheating circulation water path. The residual water in the liquid buffer chamber 91 flows back to the hot water container 42 through the return water path 13. Under the power provided by the second pump body 422 of the main unit 100, a preheating hot water circulation is formed in the preheating circulation water path. In this scheme, since the second pump body 422 provides power for the water flow, the relative positions of the distribution head 92, the mixing chamber 972 and the liquid buffer chamber 91 are not limited to being arranged in sequence from top to bottom. A fourth check valve 174 is provided at the connection between the liquid buffer chamber 91 and the mixing chamber 972. The fourth check valve 174 is used to prevent water in the mixing chamber 972 from entering the liquid buffer chamber 91 after the user has taken water, thus avoiding the risk of the water level in the hot water container 42 rising and overflowing. At the same time, the fourth check valve 174 is also used to prevent hot water in the liquid buffer chamber 91 from flowing to the distributor 92 when a preheated hot water circulation is formed in the preheating circulation water circuit, which would cause the distributor 42 to overflow during the preheated hot water circulation stage and affect the user experience. It should be understood that in this solution, when the water purifier distributor 900 stops distributing water, the water in the distributor 92 and the mixing chamber 972 is prevented from flowing back by the fourth check valve 174, and the water in the liquid buffer chamber 91 can flow back to the hot water container 42 of the main unit 100 through the return water circuit 13.

[0442] Furthermore, when the preheating water circulation ends, the return water path 13 is blocked to prevent residual water in the liquid buffer chamber 91 from flowing back into the hot water container 42 through the return water path 13, which could cause the water level in the hot water container 42 to rise abnormally or even overflow.

[0443] Furthermore, such as Figure 34 As shown, the fourth check valve 174 is located inside the outlet end of the liquid buffer chamber 91.

[0444] Of course, the fourth check valve 174 may not be installed at the connection between the liquid buffer chamber 91 and the mixing chamber 972, such as... Figure 19As shown, by installing a thermostat 94 inside the water distributor 900, and limiting the lowest point D2 of the detection end of the thermostat 94 to be above the mixing chamber 972, when the thermostat 94 obtains temperature information, it indicates that hot water in the liquid buffer chamber 91 has entered the mixing chamber 972, and there is a risk of hot water overflowing from the mixing chamber 972 or an overflow has already occurred. Figure 31 As shown, the second pump 422 is shut off, stopping the preheating water circulation. The hot water in the mixing chamber 972 flows back to the liquid buffer chamber 91, and may even flow back to the hot water container 42 via the return water path 13, thereby preventing the risk of preheating water circulation overflow. Further, in one embodiment, when the preheating water circulation stops and the thermostat 94 does not receive temperature information, it indicates that the overflow risk has been eliminated, and the second pump 422 is turned on to resume the preheating water circulation. In another embodiment, when the preheating water circulation stops for a preset duration, it indicates that the overflow risk has been eliminated, and the second pump 422 is turned on to resume the preheating water circulation.

[0445] The preset temperature value inside the hot water container 42 is set to T1, the temperature of the room temperature water provided by the first water channel 11 is set to T2, and the target water temperature is set to T. m The preset temperature T1 inside the hot water container 42 is 82-88℃, preferably 85℃, to prevent repeatedly boiled water from forming inside the hot water container 42. In this embodiment, water intake includes the following four modes:

[0446] (1) When T m =T1, the user's water target is the second level of hot water (e.g., 85℃ water). The hot water in the hot water container 42 can be used directly. The water in the hot water container 42 flows through the hot water supply channel 12, the liquid buffer chamber 91 and the mixing chamber 972 in sequence and then flows into the distributor 92, and is distributed to the user through the distributor 92.

[0447] (2) When T m =T2, the user’s water target is room temperature water. The room temperature water in the first water channel 11 can be used directly. The water in the first water channel 11 flows into the distribution head 92 after passing through the room temperature water chamber 971 and the mixing chamber 972 in sequence, and is distributed to the user through the distribution head 92.

[0448] (3) When T2 < T m When the temperature is less than T1, the user's target water temperature is the first level of hot water (e.g., 45℃). This water temperature is between the water temperature in the hot water container 42 and the ambient water temperature. The water flow in the hot water container 42 and the water flow in the first water path 11 mix in the mixing chamber 972. By controlling the mixing amount of ambient water and hot water, the desired water temperature (e.g., 45℃) is achieved. That is, the temperature obtained by mixing is T. m The water then flows into the distributor 92 and is distributed to the user via the distributor 92.

[0449] (4) When T m When the temperature is greater than T1, the user's target water temperature is the third level of hot water (e.g., 95℃). The water temperature exceeds the hot water temperature in the hot water container 42. The water in the hot water container 42 is heated by the heating element 6 and then flows into the distribution head 92 through the liquid buffer chamber 91, and is distributed to the user through the distribution head 92.

[0450] In one embodiment, the integrated water circuit component 7 has a fifth check valve 175 on its sixth flow channel 736, which connects the third filter cartridge outlet 7252 and the second purified water outlet 7262, to prevent purified water in the purified water container 41 from flowing to the first water circuit 11.

[0451] In one implementation, such as Figure 31 As shown, the third valve 143 is a two-way valve, and the third valve 143 is installed on the second hot water pipe 122 of the hot water supply circuit 12.

[0452] It should be understood that when comparing various height values ​​in this article, the corresponding height values ​​are determined based on the same horizontal reference plane.
