Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a water outlet structure and a water purifier. Background Technology

[0002] Water purifiers are devices that integrate water purification, drinking, and heating functions. However, their accompanying hot water faucets commonly face the problem of vapor-liquid separation. Existing faucets use a baffle to divide the water vapor separation chamber into a water outlet chamber and a steam outlet chamber. Hot water enters the water outlet chamber from the inlet and exits from the outlet, while the separated water vapor enters the steam outlet chamber above the water vapor separation chamber and exits from the vent.

[0003] During the flow of hot water, if the internal air bubbles cannot separate from the water, they will be discharged from the outlet along with the hot water. After the hot water containing air bubbles is discharged from the drain, the constraint force on the air bubbles decreases or even disappears, resulting in expansion or collapse. When the air bubbles are inside the water flow, their expansion can cause the water flow to become skewed, and their collapse can cause the water flow to be interrupted. When the air bubbles are outside the water flow, their collapse can cause the water to splash. Therefore, air bubbles affect the shape of the hot water outlet, resulting in a poor user experience.

[0004] Therefore, there is an urgent need to study a water outlet structure and a water purifier to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a water outlet structure and a water purifier to solve the problems in the prior art that are easy to cause water flow interruption, tilting, and air bubbles when hot water is discharged due to insufficient venting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The water outlet structure includes a shell with an internal water vapor separation chamber. The shell has a first water inlet communicating with the water vapor separation chamber. The bottom of the shell has a first water outlet channel and a second water outlet channel communicating with the water vapor separation chamber. The inlet of the second water outlet channel is higher than the inlet of the first water outlet channel. A bubble cutter is provided inside the shell. The bubble cutter is located at the bottom of the water vapor separation chamber and is situated on the flow path of the fluid entering from the first water inlet.

[0008] As an optional technical solution for the water outlet structure, the housing includes a water outlet base and a cover. The water outlet base has a water vapor separation groove, and the first water outlet channel and the second water outlet channel are both located at the bottom of the water outlet base. The cover is placed on the water outlet base and forms the water vapor separation chamber.

[0009] As an optional technical solution for the water outlet structure, the bottom of the water outlet base protrudes upward to form a bubble cutter, and the first water inlet is disposed on the water outlet base.

[0010] As an optional technical solution for the water outlet structure, the bubble cutter is elongated along the fluid movement direction, and the width of the bubble cutter first increases and then decreases.

[0011] As an optional technical solution for the water outlet structure, the bottom of the water outlet base is provided with a first water-blocking rib protruding towards the cover between the first water outlet channel and the second water outlet channel. The first water-blocking rib divides the water vapor separation tank into a first tank and a second tank, and there is a gap between the first tank and the cover. The first tank is connected to the first water outlet channel, and the second tank is connected to the second water outlet channel.

[0012] As an optional technical solution for the spout structure, the first water-blocking rib is flared, with the opening facing the first water inlet; and / or,

[0013] The bottom of the water outlet base has several reinforcing ribs protruding into the cover body in the second groove. The reinforcing ribs are connected between the side wall of the water outlet base and the first water-blocking rib.

[0014] As an optional technical solution for the water outlet structure, the interior of the housing is provided with a baffle assembly to form an intermediate flow channel. The intermediate flow channel extends along the length of the housing and is located between the first water inlet and the first water outlet.

[0015] As an optional technical solution for the water outlet structure, the housing further includes a first water outlet cylinder and a second water outlet cylinder.

[0019] This utility model has at least the following beneficial effects:

[0020] This utility model provides a water outlet structure and a water purifier. The water outlet structure includes a shell with an internal water vapor separation chamber. The shell has a first water inlet communicating with the water vapor separation chamber. The bottom of the shell has a first water outlet channel and a second water outlet channel communicating with the water vapor separation chamber. The inlet of the second water outlet channel is higher than the inlet of the first water outlet channel. A bubble-cutting element is installed inside the shell, located at the bottom of the water vapor separation chamber and in the flow path of the fluid entering from the first water inlet. After hot water flows through the bubble-cutting element, larger air bubbles inside are broken, and the internal gas separates from the hot water. The gas then moves upward with the steam to a higher position and flows into the inlet of the second water outlet channel. Through flow control, the hot water flow process does not cross the inlet of the second water outlet channel, thus flowing out through the first water outlet channel. Because the steam and internal gas separate from the hot water, the possibility of water flow interruption, skewness, and air bubbles in the water is greatly reduced during the hot water flow process, improving the water shape and user experience.

[0031] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0032] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0033] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0034] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0035] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0036] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0037] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0038] like Figures 1 to 4 As shown, this embodiment provides a water dispensing device, which can be a water purifier, a water dispenser, or a coffee machine. For ease of explanation, a water purifier is used as an example. The water purifier provides room temperature water and hot water. It includes a spout structure and a heating element. The heating element is located upstream of the spout structure and heats the room temperature water entering the spout structure to form hot water. The room temperature water has a temperature range of 5℃-40℃. The hot water has a temperature range of 50℃-100℃. When hot water flows out of the spout structure, problems such as water flow interruption, skewness, and splashing can easily occur, affecting the water flow pattern and user experience. Therefore, this embodiment proposes a spout structure to solve the above problems.

[0039] The water outlet structure includes a housing 100 with an internal water vapor separation chamber. The housing 100 has a first water inlet 130 communicating with the water vapor separation chamber. The bottom of the housing 100 has a first water outlet channel 150 and a second water outlet channel 160 communicating with the water vapor separation chamber, with the inlet of the second water outlet channel 160 higher than the inlet of the first water outlet channel 150. A bubble cutter 111 is disposed inside the housing 100, located at the bottom of the water vapor separation chamber and along the flow path of the fluid entering from the first water inlet 130. In this embodiment, a heating element is located upstream of the first water inlet 130 and heats the water entering the first water inlet 130. Of course, in other embodiments, the water outlet structure can also be applied to other drinking water devices capable of discharging hot water, such as water dispensers and coffee machines.

[0040] With the above-mentioned structure, after the hot water flows through the bubble cutter 111, the larger air bubbles inside will be cut and broken. The internal gas will separate from the hot water and move upward with the steam to a higher position and flow into the inlet of the second water outlet channel 160 and then out through the second water outlet channel 160. Through flow control, the hot water flow process will not cross the inlet of the second water outlet channel 160, so that it only flows out of the first water outlet channel 150. Since the steam and internal gas are separated from the hot water, the possibility of water flow interruption, skewness and air bubbles in the water is greatly reduced during the hot water flow process, improving the water shape and user experience.

[0041] Regarding the structure of the housing 100, in some embodiments, the housing 100 includes a water outlet base 110 and a cover 120. The water outlet base 110 has a water vapor separation groove, and the first water outlet channel 150 and the second water outlet channel 160 are both located at the bottom of the water outlet base 110. The cover 120 covers the water outlet base 110 and forms a water vapor separation chamber. The separate housing 100 facilitates production and helps improve production and assembly efficiency.

[0042] The bottom of the water outlet base 110 protrudes upward to form a bubble-cutting component 111, and the first water inlet 130 is located on the water outlet base 110. This structure allows hot water to directly impact the bubble-cutting component 111, causing the internal bubbles to burst. In addition, the bubble-cutting component 111 and the water outlet base 110 are integrally formed, reducing the number of parts and improving the assembly efficiency of the equipment.

[0043] To improve the impact resistance of the bubble cutter 111, in some embodiments, the bubble cutter 111 is elongated along the fluid flow direction. This design ensures that the bubble cutter 111 has sufficient strength to prevent breakage due to prolonged impact; simultaneously, the elongated structure prevents bubbles from re-closing after passing through the bubble cutter 111. Furthermore, the width of the bubble cutter 111 first increases and then decreases in a direction perpendicular to the fluid flow direction. This dimensional limitation of the bubble cutter 111 helps to ensure its own strength while improving the bubble cutting effect. The bubble cutter 111 is plate-shaped and extends upward from the bottom of the water outlet base 110.

[0044] The bottom of the water outlet base 110 has a first water-blocking rib 114 protruding towards the cover 120 between the first water outlet channel 150 and the second water outlet channel 160. The first water-blocking rib 114 divides the water vapor separation tank into a first tank 112 and a second tank 113, and has a gap with the cover 120. The first tank 112 is connected to the first water outlet channel 150, and the second tank 113 is connected to the second water outlet channel 160. This arrangement allows hot water to flow out of the first inlet 130 and enter the first tank 112. Then, the steam and gas in the hot water pass over the first water-blocking rib 114 and enter the second tank 113. The entire water outlet base 110 can be shell-shaped, which helps to reduce material usage. At the same time, without changing the total volume of the water vapor separation chamber, the volume of the first tank 112 and the second tank 113 is increased. The hot water flows a greater distance and for a longer time in the first tank 112, providing more space and time for water vapor separation.

[0045] To reduce large turns and impacts during hot water flow and prevent gas from returning to the hot water, the first baffle 114 is flared, with the opening facing the first inlet 130. The aforementioned first baffle 114 guides the flow of hot water, helping to reduce the impact during flow and lowering the possibility of gas returning to the hot water.

[0046] To improve the strength of the first reinforcing rib 115, in some embodiments, the bottom of the water outlet base 110 is provided with a plurality of reinforcing ribs 115 protruding into the cover 120 in the second groove 113, and the reinforcing ribs 115 are connected between the side wall of the water outlet base 110 and the first water-blocking rib 114.

[0047] The housing 100 has an internal baffle assembly forming an intermediate flow channel, which extends along the length of the housing 100. A first water outlet channel 150 is located on the extension line of the intermediate flow channel and is positioned between the first water inlet 130 and the first water outlet channel 150. The housing 100 also has a second water inlet 140 communicating with a water vapor separation chamber. The water temperature entering through the second water inlet 140 is lower than that entering through the first water inlet 130. Specifically, hot water is introduced through the first water inlet 130, and room temperature water is introduced through the second water inlet 140. The first water inlet 130 and the second water inlet 140 are spaced apart in the width direction of the housing 100; in other words, the first water outlet channel 150 is located between the first water inlet 130 and the second water inlet 140 in the width direction of the housing 100.

[0048] Specifically, the baffle assembly includes a second baffle 116 on the water outlet base 110 and a third baffle 121 and a baffle plate 122 on the cover 120. The second baffle 116 and the third baffle 121 abut against each other and are both located in the extension direction of the first water inlet 130. Along the width direction of the water outlet base 110, the baffle plate 122 and the third baffle 121 are arranged at intervals to form an intermediate flow channel. The above arrangement allows one side wall of the baffle plate 122 to guide the hot water, thereby allowing the hot water to enter the first water outlet channel 150 with the shortest distance, increasing the hot water flow rate; at the same time, it avoids the hot water flowing through multiple areas, reducing heat loss in the hot water and ensuring the outlet water temperature; finally, it reduces the range of air contact during the flow process, reducing the probability of air dissolving into the hot water, thereby improving the water shape of the outlet. In addition, the other side wall of the baffle 122 guides the room temperature water, allowing it to enter the first water outlet channel 150 and the second water outlet channel 160 with the shortest distance, thus increasing the outflow speed of the room temperature water. At the same time, it reduces the range of air contact during the flow process, reducing the probability of air dissolving into the room temperature water, thereby improving the water shape at the outlet.

[0049] The cover 120 extends towards the water outlet base 110 and is provided with a fourth water-blocking rib 123. The fourth water-blocking rib 123 is located downstream of the middle channel and has a gap with the water outlet base 110. Hot water moves downward from the middle channel and bypasses the fourth water-blocking rib 123, and then moves upward. This process, with the help of inertia, will promote better upward separation of steam and gas in the water, thereby improving the water vapor separation effect.

[0050] In some embodiments, the inner diameter of the first inlet 130 is smaller than the inner diameter of the second inlet 140, so that when the pressure is the same, the water flow rate entering the water vapor separation chamber through the first inlet 130 is less than the water flow rate entering the water vapor separation chamber through the second inlet 140. This arrangement ensures that, given a greater demand for room temperature water than for hot water, the water pressure in the second inlet 140 is equal to or even less than the water pressure in the first inlet 130, reducing the water flow velocity and thus making the water flow as gentle as possible. This prevents turbulent water from mixing with air and helps maintain the shape of the room temperature water flowing out from the first outlet channel 150 and the second outlet channel 160.

[0051] In some embodiments, combined with Figure 2 As shown, the housing 100 further includes a first water outlet cylinder 210, which communicates with the first water outlet channel 150, and the inner wall of the first water outlet cylinder 210 is provided with a first guide rib 211; the housing 100 also includes a second water outlet cylinder 220, which communicates with the second water outlet channel 160, and the inner wall of the second water outlet cylinder 220 is provided with a second guide rib 221. A plurality of first guide ribs 211 are evenly distributed around the circumference of the first water outlet cylinder 210, which helps to ensure the water shape of hot or room temperature water. A plurality of second guide ribs 221 are evenly distributed around the circumference of the second water outlet cylinder 220, which helps to ensure the water shape of room temperature water. The first water outlet cylinder 210 is located inside the second water outlet cylinder 220.

[0052] If the flow rate of the water purifier is very high, the flow of room temperature water will cause water dispersion when it flows out of the outlet of the second water outlet 220. To address this, in some embodiments, the lower end of the second water outlet 220 is provided with an annular water-gathering rib 222. When the flow rate of room temperature water is high, the water-gathering rib 222 can concentrate the water flow and prevent it from dispersing, thus ensuring the water output effect.

[0053] In some embodiments, the water outlet base 110 is provided with an annular cylinder 117, the inner side of the annular cylinder 117 is threaded, the outer side of the second water outlet cylinder 220 is threaded, and the second water outlet cylinder 220 is located inside the annular cylinder 117 and is screwed to it. This arrangement makes the second water outlet cylinder 220 easier to design and process, reducing manufacturing difficulty.

[0054] Reference Figure 3 As shown, the dashed line represents the steam flow path; the arrow in the first inlet 130 indicates the flow path of hot water and steam. (Refer to...) Figure 4 As shown, the arrow at the second inlet 140 indicates the flow path of room temperature water; the arrows at the first outlet 210 located in the second outlet 220 also indicate the flow path of room temperature water.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
