Description

Technical Field

[0001] This disclosure relates to the field of household appliance technology, and in particular to a water outlet component and a hot water treatment device. Background Technology

[0002] Hot water treatment devices are mainly used to provide users with the hot water they need for daily life. Currently, in the design of hot water treatment devices, it is sometimes necessary to output water of multiple temperatures, but the water tank only has one outlet. Therefore, water of different temperatures needs to be mixed at the outlet and discharged. If there is no suitable mixing structure, the temperature at the final outlet will fluctuate greatly, resulting in a poor user experience. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this disclosure provides a water outlet component and a hot water treatment device.

[0004] This disclosure provides a water outlet component, comprising: a housing, the housing including a flow guiding region and a mixing region, wherein water in the flow guiding region flows to the mixing region; the flow guiding region has a first water supply section and a second water supply section, the first water supply section being positioned higher than the second water supply section, such that water discharged from the first water supply section flows to the second water supply section and flows together with water discharged from the second water supply section into the mixing region; the mixing region has a water outlet for discharging water from the mixing region.

[0005] Because the first water supply unit is positioned higher than the second water supply unit, the water discharged from the first unit flows towards the second unit. When mixing is needed, water first flows from the first unit towards the second unit. In other words, after the water from the first unit reaches the second unit, the second unit discharges water, causing initial mixing of the two streams at the second unit's location. Then, the water flows together to the mixing area for further mixing before being discharged through the outlet. This simultaneous mixing of the first and second water supply units in the mixing area, ensuring thorough mixing before discharge, avoids significant temperature fluctuations in the discharged water, resulting in a better user experience.

[0006] Optionally, the flow guiding area also has an inclined section, with the first water supply section located at a first position on the inclined section and the second water supply section located at a second position on the inclined section. The first position is higher than the second position, so that the water discharged from the first water supply section flows along the inclined section to the second position and flows together with the water discharged from the second water supply section into the mixing area. Because the first position is higher than the second position, the water discharged from the first water supply section will flow along the inclined section towards the second water supply section. That is, after the water discharged from the first water supply section flows to the second position, the second water supply section discharges water. At this time, the water discharged from the first water supply section and the water discharged from the second water supply section will initially mix at the second position, and then flow together into the mixing area for further mixing. Finally, the mixed water is discharged to the outside through the outlet. This avoids large fluctuations in the temperature of the water discharged from the outlet, resulting in a better user experience.

[0007] Optionally, the housing also includes a channel through which water in the guide zone flows to the mixing zone. By providing the channel, the water in the guide zone undergoes secondary mixing before finally flowing to the mixing zone for further mixing. Therefore, the water, after multiple mixing processes, becomes more uniform, resulting in less temperature fluctuation in the water discharged from the outlet and a better user experience.

[0008] Optionally, the channel and the guide area are arranged side by side, which makes the structure of the water outlet component more compact and reduces the size of the water outlet component. The channel has an inlet and an outlet, and the flow direction of the water from the first water supply unit to the second water supply unit is opposite to the flow direction of the water from the inlet to the outlet. In this case, it is equivalent to the inlet being set closer to the second position and the outlet being set closer to the first position. A stream of water discharged from the first water supply unit will first be discharged to the first position and then flow from the first position to the second position. When it flows to the second position, a stream of water discharged from the second water supply unit will also be discharged to the second position. The two streams of water initially mix at the second position and then flow into the channel, where they mix again before flowing into the mixing area. Since the water turns when flowing from the second position to the channel, the turning point facilitates water mixing.

[0009] Optionally, the height of the inlet is higher than or equal to the height of the outlet, which facilitates the flow of water in the channel into the mixing zone through the outlet.

[0010] Optionally, the height of the water inlet of the second water supply unit is higher than the height of the first position. Since water at the first position flows to the second position, if the height of the water inlet of the second water supply unit is the same as the second position, the water at the first position will flow into the second water supply unit. To avoid the above problem, the height of the water inlet of the second water supply unit is set higher than the height of the first position. Even when the water at the first position flows to the second position, the water can only circulate around the outer periphery of the second water supply unit. After the water in the second water supply unit is discharged, it will initially mix with the water flowing down from the first position.

[0011] Optionally, the height of the water inlet of the first water supply unit is higher than or equal to the height of the first position. The height of the water inlet of the first water supply unit can be higher than the first position or level with the first position, as long as the first water supply unit can discharge water.

[0012] Optionally, the water outlet component further includes a water supply component, which can be selectively connected to the first water supply unit and the second water supply unit to deliver water of different temperatures to the guide area through the first water supply unit and / or the second water supply unit. When the first water supply unit needs to drain, the water supply component is connected to the first water supply unit; when the second water supply unit needs to drain, the water supply component is connected to the second water supply unit, thereby enabling the water supply component to deliver water to the guide area.

[0013] Optionally, the mixing area has a receiving cavity for receiving water discharged from the guiding area; the outlet has a water outlet pipe connected to the receiving cavity, and at least a portion of the water outlet pipe is located within the receiving cavity for discharging water from the receiving cavity. The receiving cavity receives water discharged from the guiding area. Because the water outlet pipe is connected to the receiving cavity, water in the receiving cavity can be discharged from the water outlet pipe. Furthermore, due to the design of the water outlet pipe, water will only flow out of the outlet pipe when the water in the receiving cavity reaches a certain height, thus extending the mixing time of the water in the receiving cavity and making the water mix more evenly.

[0014] Optionally, the mixing area has an exhaust pipe, the top of which is higher than the top of the outlet pipe. The exhaust pipe allows for the removal of high-temperature steam from the mixing area, preventing scalding of the user during water dispensing. Additionally, when the liquid level in the mixing area is higher than the exhaust pipe, water will flow out through the exhaust pipe to other locations, ensuring a stable water flow.

[0015] Optionally, the housing is provided with a drainage structure sleeved around the water outlet pipe, with at least a portion of the water outlet pipe extending into the drainage structure. The drainage structure includes a plate, with the top surface of the water outlet pipe located between the bottom surface of the drainage structure and the plate, and the water outlet pipe positioned close to the plate. A water outlet channel is formed between the drainage structure and the water outlet pipe. Water in the receiving cavity flows through the water outlet channel to the top surface of the water outlet pipe and is discharged from the outlet on the top surface. As water is discharged, the water level in the receiving cavity decreases. When the water level in the receiving cavity is lower than the top surface of the water outlet pipe but higher than the bottom surface of the drainage structure, water can continue to be discharged until the water level in the receiving cavity is lower than the bottom surface of the drainage structure, at which point the water discharge stops, thus preventing water from accumulating in the receiving cavity.

[0016] Optionally, the mixing area has a groove, and the bottom surface of the drainage structure is positioned close to or extends into the groove, so that the water outlet channel communicates with the groove. The groove design avoids the gap between the bottom surface of the drainage structure and the bottom surface of the receiving cavity being too small, thus preventing drainage from being affected, and ensures that only a very small amount of water remains in the groove.

[0017] Optionally, the sum of the volume of water discharged from the first water supply unit and the volume of water discharged from the second water supply unit at one time is less than or equal to the volume of the receiving cavity. Since the water discharged from the first water supply unit and the second water supply unit flows into the receiving cavity simultaneously, if the volume of the receiving cavity is too small, water backflow or overflow may easily occur. Therefore, the volume of water discharged from the first water supply unit and the second water supply unit is limited so that the water in the receiving cavity is discharged through the outlet pipe.

[0018] A second aspect of this disclosure provides a hot water treatment device, comprising: a water tank and the aforementioned water outlet component, the water outlet component being installed on top of the water tank, and water from the water tank being supplied to the first water supply section and the second water supply section in the water outlet component, thus the hot water treatment device having all the beneficial effects of the water outlet component.

[0019] Additional aspects and advantages of this disclosure will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0030] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0031] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0032] Reference Figures 1 to 6As shown, the water outlet component provided in this embodiment includes a housing 100, which includes a flow guiding region 1 and a water mixing region 2. Water in the flow guiding region 1 flows into the water mixing region 2 and is then discharged through the outlet 21 in the water mixing region 2. The flow guiding region 1 has a first water supply section 11 and a second water supply section 12. The first water supply section 11 is positioned higher than the second water supply section 12. Under the influence of gravity, the water discharged from the first water supply section 11 flows towards the second water supply section 12. When mixing water, water first flows out from the first water supply unit 11. Under the influence of gravity, the water flows towards the second water supply unit 12. After the water from the first water supply unit 11 reaches the location of the second water supply unit 12, the second water supply unit 12 then discharges water. At this time, the water from the first water supply unit 11 and the water from the second water supply unit 12 will initially mix at the location of the second water supply unit 12, and then flow together into the mixing area 2. After being fully mixed in the mixing area 2, the mixed water is discharged to the outside through the outlet 21. Because the water discharged from the first water supply unit 11 and the water discharged from the second water supply unit 12 flow into the mixing area 2 simultaneously for mixing, the mixing is relatively uniform. After mixing, the water is discharged through the outlet 21, avoiding large temperature fluctuations in the water discharged from the outlet 21, resulting in a better user experience and a simple structure.

[0033] The flow guiding area 1 also has an inclined section 13. A first water supply unit 11 is located at a first position 14 on the inclined section 13, and a second water supply unit 12 is located at a second position 15 on the inclined section 13. The first position 14 is higher than the second position 15, so that the water discharged from the first water supply unit 11 flows along the inclined section 13 towards the second position 15, and together with the water discharged from the second water supply unit 12 flows into the mixing area 2. Because the first position 14 is higher than the second position 15, the water discharged from the first water supply unit 11 flows along the inclined section 13 towards the second water supply unit 12. That is, after the water discharged from the first water supply unit 11 reaches the second position 15, the second water supply unit 12 discharges water. At this time, the water discharged from the first water supply unit 11 and the water discharged from the second water supply unit 12 will initially mix at the second position 15, and then flow together into the mixing area 2 for further mixing. Finally, the mixed water is discharged to the outside through the outlet 21. This avoids significant temperature fluctuations in the water discharged from the outlet 21, resulting in a better user experience.

[0034] In practical use, it is equivalent to the first water supply unit 11 discharging a stream of water and the second water supply unit 12 discharging a stream of water. The two streams of water will first mix at the second position 15, and then flow together to the mixing area 2 to mix. After mixing, they are discharged through the outlet 21. Since the two streams of water have been mixed twice, the mixing is more uniform, thus avoiding large fluctuations in the temperature of the water discharged from the outlet 21, resulting in a better user experience.

[0035] The first water supply unit 11 and the second water supply unit 12 described above can drain water periodically. When water is first discharged (here, "one water supply" refers to supplying water to the first water supply unit 11 once), the first water supply unit 11 discharges water first. After the water discharged from the first water supply unit 11 flows to the second position 15, the second water supply unit 12 discharges water again. At this time, the water discharged from the first water supply unit 11 and the water discharged from the second water supply unit 12 will initially mix at the second position 15, which is the first cycle. Then, the first water supply unit 11 discharges water again. After the water discharged from the first water supply unit 11 flows to the second position 15, the second water supply unit 12 also discharges water again. At this time, the water discharged from the first water supply unit 11 and the water discharged from the second water supply unit 12 will initially mix at the second position 15, which is the second cycle. Therefore, the water outlet components can perform multiple cycles of drainage, thereby achieving periodic water supply from the first water supply unit 11 and the second water supply unit 12.

[0036] For example, after the first water supply unit 11 drains, it takes 2 seconds for the water discharged from the first water supply unit 11 to reach the second position 15, and the second water supply unit 12 drains 2 seconds later, so that the two streams of water flow synchronously to the mixing area 2. The time here is determined by the distance between the first position 14 and the second position 15, and the inclination of the inclined part 13. Of course, the above parameters have been set when assembling the water outlet components. Since the two drain outlets in the prior art drain water at the same time, some water will flow to the mixing area 2 first, and then the other part of the water will flow to the mixing area 2. Therefore, it is impossible to mix evenly in the mixing area 2, resulting in a large fluctuation in the temperature of the finally discharged water, which leads to a poor user experience. The present disclosure solves this problem and improves the user experience.

[0037] In some embodiments, the water outlet component further includes a water supply component, which may selectively communicate with the first water supply section 11 and the second water supply section 12 to deliver water of different temperatures through the first water supply section 11 and / or the second water supply section 12 to the flow guiding area 1. When the first water supply section 11 needs to drain, the water supply component communicates with the first water supply section 11; when the second water supply section 12 needs to drain, the water supply component communicates with the second water supply section 12, thereby enabling the water supply component to deliver water to the flow guiding area 1.

[0038] The first water supply unit 11 and the second water supply unit 12 cannot discharge water simultaneously. The first water supply unit 11 is used to discharge low-temperature water, and the second water supply unit 12 is used to discharge high-temperature water. When low-temperature water is needed, only the first water supply unit 11 discharges water; when high-temperature water is needed, only the second water supply unit 12 discharges water; when mixed water is needed, the first water supply unit 11 and the second water supply unit 12 can discharge water alternately, so that low-temperature water and high-temperature water can mix in the mixing zone 2 and then be discharged through the outlet 21.

[0039] Of course, the temperature of the water discharged from outlet 21 is determined according to the user's needs. For example, the water outlet component has three buttons: the first button controls the discharge of low-temperature water, the second button controls the discharge of mixed warm water, and the third button controls the discharge of high-temperature water. When the first button is pressed, the second water supply unit 12 does not discharge water, and the first water supply unit 11 discharges low-temperature water. The low-temperature water flows through the guide area 1 to the mixing area 2 and is discharged through outlet 21. When the third button is pressed, the first water supply unit 11 does not discharge water, and the second water supply unit 12 discharges high-temperature water. The high-temperature water flows through the guide area 1 to the mixing area 2 and is discharged through outlet 21. When the second button is pressed, the first water supply unit 11 discharges water first. After the water discharged from the first water supply unit 11 flows to the second position 15, the second water supply unit 12 discharges water. At this time, the water discharged from the first water supply unit 11 and the water discharged from the second water supply unit 12 will be initially mixed at the second position 15, and then flow together into the mixing area 2 and be discharged through outlet 21. This has the advantages of uniform mixing and a good user experience.

[0040] The aforementioned water supply components can be connected to the first water supply unit 11 and the second water supply unit 12 via a three-way valve. A heat exchange component is installed between the three-way valve and the first water supply unit 11 to reduce the temperature of the water exiting the first water supply unit 11, thus enabling the first water supply unit 11 to discharge low-temperature water. The three-way valve is directly connected to the second water supply unit 12, allowing the second water supply unit 12 to discharge high-temperature water. When the user requires low-temperature water, the three-way valve is only connected to the first water supply unit 11, and the first water supply unit 11 discharges low-temperature water, which flows through the guide area 1 to the mixing area 2. When the user requires high-temperature water, the three-way valve is only connected to the second water supply unit 12, and the second water supply unit 12 discharges high-temperature water, which flows through the guide area 1 to the mixing area 2. When a user needs warm water, the three-way valve first connects to the first water supply unit 11 to supply water. When the water discharged from the first water supply unit 11 flows to the second position 15, the three-way valve then connects to the second water supply unit 12 to supply water. This allows the water discharged from the second water supply unit 12 to initially mix with the water discharged from the first water supply unit 11 and then flow together into the mixing area 2. This has the advantage of simple structure.

[0041] The aforementioned water supply components are electrically connected to the control components. After receiving a signal, the control components control the three-way valve to connect with the first water supply unit 11 or the second water supply unit 12, thereby supplying water.

[0042] In some embodiments, such as Figure 2 and Figure 3As shown, the height of the water inlet of the second water supply section 12 is higher than the height of the first position 14. Since the water at the first position 14 flows to the second position 15, if the height of the water inlet of the second water supply section 12 is the same as that of the second position 15, the water at the first position 14 will flow into the second water supply section 12. To avoid this problem, the height of the water inlet of the second water supply section 12 is set higher than that of the first position 14. Even when the water at the first position 14 flows to the second position 15, the water can only circulate around the outer periphery of the second water supply section 12. After the water from the second water supply section 12 is discharged, it initially mixes with the water flowing down from the first position 14, and then flows into the mixing area 2. Here, the second water supply section 12 can be set as a water supply pipe, that is, the top surface of the water supply pipe is higher than the height of the first position 14.

[0043] Wherein, the height of the water inlet of the first water supply section 11 is higher than or equal to the height of the first position 14. When the height of the water inlet of the first water supply section 11 is level with the first position 14, the water discharged from the water inlet can flow directly to the inclined section 13. When the height of the water inlet of the first water supply section 11 is higher than the first position 14, the water discharged from the water inlet can flow out along the outer wall of the first water supply section 11. The specific structure is not specifically limited here, as long as the first water supply section 11 can discharge water.

[0044] Furthermore, the volume of water discharged from the first water supply unit 11 at one time can be equal to the volume of water discharged from the second water supply unit 12 at one time. The first water supply unit 11 discharges low-temperature water, and the second water supply unit 12 discharges high-temperature water. Since their volumes are the same, it is only necessary to control the temperature of the low-temperature water discharged from the first water supply unit 11 and the high-temperature water discharged from the second water supply unit 12 to obtain water at the desired target temperature, which is then discharged through the outlet 21. Here, the high-temperature water can be 100 degrees Celsius, and the low-temperature water can be 25 degrees Celsius, 45 degrees Celsius, or 60 degrees Celsius.

[0045] Combination Figures 2-4 As shown, the housing 100 also includes a channel 3. Water in the guide area 1 flows to the mixing area 2 through the channel 3. By setting the channel 3, the water in the guide area 1 can be mixed again in the channel 3, and the mixing time is extended to provide a mixing effect. After mixing, it flows to the mixing area 2 for further mixing. The water that has been mixed multiple times will be more uniform, so the temperature of the water discharged through the outlet 21 is more uniform and there will be no large fluctuations, resulting in a better user experience.

[0046] In this design, channel 3 and flow guiding area 1 are arranged side by side, eliminating the need for excessively long outlet components. This allows for a more compact structure of the outlet components, thereby reducing their size. Channel 3 has an inlet 31 and an outlet 32. Inlet 31 is connected to flow guiding area 1, and outlet 32 ​​is connected to mixing area 2. The water flow direction from the first water supply section 11 to the second water supply section 12 is opposite to the water flow direction from the inlet 31 to the outlet 32. At this time, it is equivalent to the inlet 31 being set away from the first position 14 and the inlet 31 being set close to the second position 15. The water discharged from the first water supply section 11 will first be discharged to the first position 14 and then flow from the first position 14 along the guide section 13 to the second position 15. When it flows to the second position 15, the water discharged from the second water supply section 12 will also be discharged to the second position 15. After initial mixing in the second position 15, it will flow into the channel 3 through the inlet 31. After mixing in the channel 3, it will then flow into the mixing area 2 through the outlet 32. At the same time, the water will turn when flowing from the second position 15 to the channel 3. Therefore, when turning, the water will collide with the inner wall of the shell, which is more conducive to the mixing of the water.

[0047] Furthermore, the height of inlet 31 is lower than the height of the second position 15, facilitating the flow of water from the second position 15 into the channel 3 through inlet 31. The height of inlet 31 is higher than or equal to the height of outlet 32. When the height of inlet 31 is higher than the height of outlet 32, it facilitates the flow of water from the channel 3 into the mixing zone 2 through outlet 32. When the height of inlet 31 is equal to the height of outlet 32, the water flow velocity allows water from the channel 3 to flow into the mixing zone 2 through outlet 32.

[0048] A partition can be provided in the aforementioned housing 100, which can divide the housing 100 into a flow guiding area 1 and a channel 3.

[0049] The inner wall of the aforementioned channel 3 can be configured as a sloping structure to facilitate the flow of water from the inlet 31 to the outlet 32.

[0050] An angle can be formed between the aforementioned channel 3 and the inclined part 13, so the water path can be V-shaped. The position of the channel 3 can reduce the size of the water outlet component and reduce the footprint.

[0051] Combination Figure 3 and Figure 4As shown, the mixing zone 2 has a receiving cavity 22 for receiving water discharged from the guiding zone 1. Meanwhile, the outlet 21 has an outlet pipe 25. Since the outlet pipe 25 is connected to the receiving cavity 22, water in the receiving cavity 22 can be discharged from the outlet pipe 25. Furthermore, since at least part of the outlet pipe 25 is located inside the receiving cavity 22, water in the receiving cavity 22 will only flow out from the top outlet of the outlet pipe 25 when it reaches a certain height (i.e., the water level is higher than the top surface of the outlet pipe 25). This further prolongs the mixing time of the water in the receiving cavity 22, allowing the water to be mixed more evenly.

[0052] The housing 100 is provided with a drainage structure 4 sleeved around the water outlet pipe 25, and the water outlet pipe 25 extends at least partially into the drainage structure 4. The drainage structure 4 includes a plate 41 (the plate 41 is located in the middle of the drainage structure 4), the top surface of the water outlet pipe 25 is located between the bottom surface of the drainage structure 4 and the plate 41, and the water outlet pipe 25 is located close to the plate 41. A water outlet channel 5 is formed between the drainage structure 4 and the water outlet pipe 25. Water in the receiving cavity 22 flows through the outlet channel 5 to the top surface of the outlet pipe 25 and is discharged from the outlet on the top surface. As water is gradually discharged, the water level in the receiving cavity 22 gradually decreases. When the water level in the receiving cavity 22 is lower than the top surface of the outlet pipe 25 but higher than the bottom surface of the drainage structure 4, under pressure, water can continue to flow from the outlet channel 5 to the top surface of the outlet pipe 25 until the water level in the receiving cavity 22 is lower than the bottom surface of the drainage structure 4, at which point the water discharge will stop, thus preventing water from accumulating in the receiving cavity 22. The outlet pipe 25 and the drainage structure 4 here use the siphon principle to discharge as much water as possible from the receiving cavity 22.

[0053] In addition, the diversion structure 4 has a diversion part and a connecting part. The diversion part is connected to the inner wall of the housing 100 through the connecting part. The diversion part is sleeved on the outer periphery of the water outlet pipe 25. The gap between the top surface of the diversion part and the top surface of the water outlet pipe 25 should not be too large, and the gap between the side wall of the diversion part and the side wall of the water outlet pipe 25 should not be too large to avoid poor diversion effect.

[0054] The aforementioned mixing area 2 has a groove 23. The bottom surface of the drainage structure 4 is positioned close to or extends into the groove 23, allowing the water outlet channel 5 to communicate with the groove 23. Water in the receiving cavity 22 flows through the groove 23 into the water outlet channel 5. The groove 23 prevents the gap between the bottom surface of the drainage structure 4 and the bottom surface of the receiving cavity 22 from being too small, thus ensuring a certain gap between them. Furthermore, when water discharge stops, only a very small amount of water remains in the groove 23. Even when the water outlet component is used again, the water in the groove 23 has virtually no impact on the temperature of the water in the entire receiving cavity 22.

[0055] The sum of the volume of water discharged from the first water supply unit 11 and the volume of water discharged from the second water supply unit 12 at one time is less than or equal to the volume of the receiving cavity 22. Since the water discharged from the first water supply unit 11 and the second water supply unit 12 flows into the receiving cavity 22 at the same time, if the volume of the receiving cavity 22 is too small, water backflow or overflow may easily occur. In order to avoid the above problems, the volume of water discharged from the first water supply unit 11 and the second water supply unit 12 is limited so that the water in the receiving cavity 22 can be smoothly discharged through the water outlet pipe 25.

[0056] The aforementioned mixing zone 2 has an exhaust pipe 24, the top of which is higher than the top of the outlet pipe 25. The exhaust pipe 24 allows for the removal of high-temperature steam from the mixing zone 2, preventing scalding of users during water dispensing and also avoiding excessive internal pressure that could affect drainage. Furthermore, when the liquid level in the mixing zone 2 is higher than the exhaust pipe 24, water will flow out through the exhaust pipe 24 to other locations, preventing backflow.

[0057] When the water in the aforementioned receiving cavity 22 reaches the top surface of the outlet pipe 25, the water begins to flow out from the outlet on the top surface. The flow rate is related to the height of the portion of the outlet pipe 25 within the receiving cavity 22; the higher the portion of the outlet pipe 25 within the receiving cavity 22, the faster the flow rate. When the total inlet velocity of the first water supply unit 11 and the second water supply unit 12 is less than the outlet velocity of the outlet pipe 25, the height of the portion of the outlet pipe 25 within the receiving cavity 22 needs to be lowered until the total inlet velocity of the first water supply unit 11 and the second water supply unit 12 is the same as the outlet velocity of the outlet pipe 25, at which point dynamic equilibrium of the liquid level can be achieved. When the total inlet velocity of the first water supply unit 11 and the second water supply unit 12 is greater than the outlet velocity of the outlet pipe 25, the height of the portion of the outlet pipe 25 within the receiving cavity 22 needs to be raised until the total inlet velocity of the first water supply unit 11 and the second water supply unit 12 is the same as the outlet velocity of the outlet pipe 25, at which point dynamic equilibrium of the liquid level can be achieved. Of course, the height of the water outlet pipe 25 located in the receiving cavity 22 was set when the water outlet component was assembled.

[0058] The hot water treatment device provided in this embodiment includes a water tank and a water outlet component. The water outlet component is installed on the top of the water tank, and water from the water tank is supplied to the first water supply section 11 and the second water supply section 12 in the water outlet component. Since the hot water treatment device provided in this embodiment has the same advantages as the water outlet component provided in this embodiment, further details are omitted here.
