[0003] The water outlet structure of the water dispenser can provide hot water. When the water outlet temperature is too high (above 95°C), the water flow is rapidly disordered and steam spraying is likely to occur. Therefore, the maximum water outlet temperature set by the water outlet temperature software of the existing water dispenser is generally 90°C-94°C, resulting in the actual measured maximum outlet temperature of only about 92°C, which limits the outlet temperature and affects the user experience.

[0060] Embodiment 1

[0061] like Figure 1 As shown, this embodiment provides a water outlet structure of a water dispenser, including a water outlet box 10. The water outlet box 10 is provided with an exhaust port 112, a hot water inlet 111, a normal temperature water inlet 122 and a water outlet 121. After hot water enters the water outlet box 10 through the hot water inlet 111, steam is discharged through the exhaust port 112. The normal temperature water inlet 122 is used to pass normal temperature water into the water outlet box 10, and the water in the water outlet box 10 flows out through the water outlet 121 for use by the user. The hot water inlet 111 is used to dock with the heating component of the water dispenser, and the hot water transported from the heating component enters the water outlet box 10 through the hot water inlet 111.

[0062] In order to ensure the exhaust effect of steam, the exhaust port 112 is set at the top of the water outlet box 10, so that the steam can be discharged during the rising process, which is conducive to the separation of steam and hot water.

[0063] In order to avoid steam spraying when hot water flows out from the water outlet 121, an upper cavity and a lower cavity arranged in a vertical direction are formed in the water outlet box 10, the exhaust port 112 and the hot water inlet 111 are both connected to the upper cavity, and the water outlet 121 and the normal temperature water inlet 122 are both connected to the lower cavity; the upper cavity and the lower cavity are connected through a connecting port.

[0064] When hot water is provided, hot water enters the upper cavity through the hot water inlet 111, flows in the upper cavity, and collides with the inner wall of the upper cavity to separate steam, and the steam is discharged upward through the exhaust port 112, and the hot water flows downward, enters the lower cavity through the connecting port, and after passing through the lower cavity, flows out through the water outlet 121 for user use. Hot water passes through the upper cavity and the lower cavity in sequence, which can increase the collision of hot water with the inner wall of the water outlet box 10, extend the flow path of hot water, and fully separate the steam in the hot water, so that the steam is discharged from the exhaust port 112, and the steam is prevented from being sprayed out from the water outlet 121 with the hot water, so as to avoid scalding the user.

[0065] When providing normal temperature water, normal temperature water enters the lower cavity through the normal temperature water inlet 122, and the water in the lower cavity flows out through the water outlet 121 for use by the user. Hot water and normal temperature water enter the water outlet box 10 through different inlets, and the hot water enters the upper cavity, and the normal temperature water enters the lower cavity, which can separate the normal temperature water and hot water water paths, and avoid the situation where the user has just finished taking hot water and continues to take normal temperature water, and the water temperature is affected by the hot water.

[0066] In order to avoid steam spraying when hot water flows out from the water outlet 121, a water retaining portion is further provided in the water outlet box 10. The water retaining portion is located downstream of the hot water inlet 111 along the hot water flow direction. The water retaining portion can collide with the hot water flowing into the water outlet box 10 through the hot water inlet 111 to separate the steam and reduce the steam carried in the hot water. The steam is discharged from the exhaust port 112, thereby avoiding steam spraying when hot water flows out from the water outlet 121.

[0067] Specifically, a water retaining rib 113 is provided in the water outlet box 10 , and the water retaining rib 113 forms at least a part of the water retaining portion. The hot water entering the water outlet box 10 can hit the water retaining rib 113 to separate the steam therein.

[0068] like Figure 2 and Figure 3As shown, the water retaining rib 113 includes a first rib plate 1131 and a second rib plate 1132 arranged at an angle, the free ends of the first rib plate 1131 and the second rib plate 1132 are connected to the inner wall of the water outlet box 10, and the side wall of the water outlet box 10 adjacent to the first rib plate 1131 and the side wall of the water outlet box 10 connected to the second rib plate 1132 are adjacent, and the first rib plate 1131 is arranged opposite to the hot water inlet 111. The water retaining rib 113 cooperates with the inner wall of the water outlet box 10, so that the front side and the opposite sides of the hot water inlet 111 along the hot water flow direction are provided with obstructions, and the hot water first hits the first rib plate 1131, and after being blocked and turned back by the first rib plate 1131, it will collide with the second rib plate 1132 and the side wall of the water outlet box 10 opposite to the second rib plate 1132, thereby improving the effect of breaking up the hot water, thereby facilitating the separation of steam in the hot water.

[0069] In this embodiment, the first rib plate 1131 and the second rib plate 1132 are vertically connected, and the two side walls of the water outlet box 10 respectively connected to the first rib plate 1131 and the second rib plate 1132 are vertical, which is beneficial to improve the effect of breaking up water.

[0070] like Figure 1 and Figure 4 As shown, the hot water inlet 111 is arranged at the upper end of the water outlet box 10, the top of the water retaining rib 113 is connected to the top surface of the water outlet box 10, and the bottom surface of the water retaining rib 113 is spaced apart from the inner wall of the water outlet box 10, so that the hot water blocked by the water retaining rib 113 can flow downward along the water retaining rib 113 to flow out through the water outlet 121.

[0071] When hot water is provided, hot water enters the upper cavity through the hot water inlet 111, separates steam by impact with the water retaining rib 113, and is discharged upward through the exhaust port 112, and the hot water flows downward, enters the lower cavity through the connecting port, and after passing through the lower cavity, flows out through the water outlet 121 for user use. When normal temperature water is provided, normal temperature water enters the lower cavity through the normal temperature water inlet 122, and the water in the lower cavity flows out through the water outlet 121 for user use.

[0072] like Figure 1 and Figure 4 As shown, the water outlet box 10 includes a shell and a top cover 13, and the shell includes a bottom shell 12 and an upper cover 11. The water outlet 121 and the normal temperature water inlet 122 are respectively arranged at opposite ends of the bottom shell 12; the upper cover 11 is arranged on the bottom shell 12, and the upper cover 11 and the bottom shell 12 form a lower cavity. The top cover 13 is arranged on the upper cover 11, and the top cover 13 and the upper cover 11 form an upper cavity, and the communication port is arranged on the upper cover 11 to connect the upper cavity and the lower cavity.

[0073] In order to prevent the hot water entering the lower cavity from moving toward the normal temperature water inlet 122, a flow guide pipe 114 is protrudingly provided on the inner wall of the lower cavity around the connecting port, and a first side outlet connected to the bottom end pipe port of the flow guide pipe 114 is provided on the side wall of the flow guide pipe 114, and the first side outlet is provided on the side of the flow guide pipe 114 facing the water outlet 121. By providing the first side outlet, on the one hand, the hot water can be guided to flow in the direction of the water outlet 121, and the hot water can be prevented from flowing back toward the normal temperature water inlet 122; on the other hand, the pipe wall of the side of the flow guide pipe 114 provided with the first side outlet is short, so that the distance between the side of the flow guide pipe 114 provided with the first side outlet and the bottom surface of the bottom shell 12 is large, and the fluid flow resistance is small, so that the normal temperature water can flow toward the water outlet 121 when passing through the flow guide pipe 114, and the normal temperature water can be prevented from flowing back when it is at the position below the flow guide pipe 114.

[0074] To ensure that water can flow out smoothly from the water outlet 121, the height of the bottom surface of the lower cavity is gradually reduced from the end with the normal temperature water inlet 122 to the end with the water outlet 121, so that water flows from high to low under the action of gravity, thereby improving the water discharge effect.

[0075] In the present embodiment, the height of the bottom surface of the bottom shell 12 gradually decreases from the edge toward the water outlet 121, forming a structure with a high edge and a low height of the water outlet 121, so that the water outlet 121 is located in the low-lying area of ​​the bottom surface of the bottom shell 12, so that the water in the lower cavity can flow toward the water outlet 121.

[0076] To ensure that the hot water in the upper cavity can smoothly enter the lower cavity, the bottom height of the upper cavity is gradually reduced from one end of the hot water inlet 111 to one end of the connecting port, so that water flows from high to low under the action of gravity, thereby improving the water discharge effect.

[0077] In this embodiment, the height of the bottom surface of the upper cover 11 gradually decreases from the edge toward the connecting port, forming a structure with a high edge and a low height of the connecting port, so that the connecting port is located in the low-lying area of ​​the bottom surface of the upper cover 11, so that the water in the upper cavity can flow toward the connecting port.

[0078] like Figure 4 As shown, an air guide tube 115 is provided in the water outlet box 10, one end of the air guide tube 115 is connected to the lower cavity, preferably one end of the air guide tube 115 extends into the lower cavity, and the other end extends into the upper cavity. By providing the air guide tube 115, the steam entering the lower cavity can enter the upper cavity through the air guide tube 115 and be discharged through the exhaust port 112, further avoiding steam spraying at the water outlet 121.

[0079] A second side outlet 1151 is provided on the side wall of the end of the air guide tube 115 extending into the lower cavity. The second side outlet 1151 is communicated with the pipe opening of the end of the air guide tube 115 extending into the lower cavity. The second side outlet 1151 is provided on the side of the air guide tube 115 facing the water outlet 121. By providing the second side outlet 1151, the pipe wall of the side of the air guide tube 115 provided with the second side outlet 1151 is shortened, so that the distance between the side of the air guide tube 115 provided with the second side outlet 1151 and the bottom surface of the bottom shell 12 is large, so that the gas in the lower cavity is better discharged from the air guide tube 115. In addition, the resistance to fluid flow is small, so that normal temperature water and hot water can flow toward the water outlet 121 when passing through the air guide tube 115, and the normal temperature water and hot water are prevented from flowing back at the position below the air guide tube 115.

[0080] One end of the air guide pipe 115 extending into the upper cavity is located below the exhaust port 112, which facilitates the steam to enter the exhaust port 112 and be discharged. The projection of the air guide pipe 115 in the horizontal plane at least partially overlaps with the projection of the exhaust port 112 in the horizontal plane, which is conducive to the discharge of steam. After the steam in the lower cavity is discharged, it can prevent the hot water from being scattered when it is discharged from the water outlet 121.

[0081] like Figure 5 As shown, two guide ribs 123 are also provided in the bottom shell 12, the first ends of the two guide ribs 123 are close to the normal temperature water inlet 122, the second ends of the two guide ribs 123 extend to the water outlet 121, the normal temperature water inlet 122 is located between the two guide ribs 123, and the connecting port is also located between the two guide ribs 123. The guide ribs 123 can allow water in the lower cavity to flow toward the water outlet 121.

[0082] The distance between the two guide ribs 123 gradually decreases from the first end to the second end, so that water gradually gathers during the flow and is discharged through the water outlet 121 .

[0083] like Figure 4 As shown, the hot water inlet 111 and the water outlet 121 are respectively located at opposite ends of the water outlet box 10, so as to further extend the flow path of the hot water in the water outlet box 10, thereby improving the gas-liquid separation effect and avoiding the problem of steam spraying at the water outlet 121. The water outlet 121 is arranged on the bottom surface of the water outlet box 10, so that the water in the water outlet box 10 can be smoothly discharged through the water outlet 121, avoiding residual water in the water outlet box 10.

[0084] Optionally, the inner bottom surface of the water outlet box 10 is tilted downward from the surrounding edges toward the water outlet 121 so that hot water can gather at the water outlet 121 to improve water outlet efficiency.

[0085] In this embodiment, the normal temperature water inlet 122 in the water outlet structure of the water dispenser is used to introduce normal temperature water into the water outlet box 10, so that the water outlet structure of the water dispenser can provide normal temperature water to the user. Hot water and normal temperature water enter the water outlet box 10 through different entrances, further realizing the separation of the normal temperature water and hot water water paths, avoiding the situation where the water temperature is affected by the hot water when the user has just finished taking hot water and continues to take normal temperature water.

[0086] The normal temperature water inlet 122 is arranged on the bottom surface of the water outlet box 10, and the normal temperature water inlet 122 and the water outlet 121 are respectively arranged at the opposite ends of the water outlet box 10, and the hot water inlet 111 is located above the normal temperature water inlet 122, so that the hot water inlet 111 and the normal temperature water inlet 122 are both at a certain distance from the water outlet 121 to ensure the full discharge of gas in the hot water water path, thereby ensuring the water shape of the hot water or normal temperature water finally flowing out of the water outlet 121.

[0087] In this embodiment, the water outlet structure of the water dispenser also includes a lighting component 20, which is arranged on the water outlet box 10. On the one hand, the lighting component 20 can sterilize the water and improve the hygiene of drinking water. On the other hand, it can illuminate the water in the water outlet box 10 to avoid scalding, spilling, etc. caused by dim light at the water outlet 121 when the user receives water.

[0088] Specifically, the lighting assembly 20 includes a lamp holder 21 and a lamp group 22. A mounting hole is provided on the water outlet box 10, and the mounting hole is located directly above the water outlet 121. The lamp holder 21 is disposed in the mounting hole. The lamp group 22 includes a circuit board and at least one of a lighting lamp and an ultraviolet lamp disposed on the circuit board. The circuit board is disposed on the lamp holder 21, and the lighting lamp and the ultraviolet lamp are disposed on a side surface of the circuit board facing the inside of the water outlet box 10, so that the light emitted by the lighting lamp and the ultraviolet light emitted by the ultraviolet lamp are both emitted into the water in the water outlet box 10, and the ultraviolet light disinfects the water. The light emitted by the lighting lamp and the ultraviolet light is used to illuminate the water, so that the outlet water flow is bright, thereby illuminating the vicinity of the water outlet 121, and avoiding scalding or spilling of water when the user receives water.

[0089] Compared with setting a lighting lamp outside the water outlet box 10 and around the water outlet 121, in this embodiment, the lighting lamp and the ultraviolet lamp are integrated on the circuit board, and the water outlet 121 is illuminated by illuminating the water flow, which is conducive to simplifying the structure.

[0090] Since water has a high light transmittance, most of the light is directly transmitted through it, and only a small part of the light can be absorbed and scattered by the water, resulting in low brightness of the water. In order to improve the degree of illumination of the water by the lighting lamp, the lighting assembly 20 also includes a guide member, which is arranged at the water outlet 121 and is used to break up the water flow so that the light is reflected multiple times in the water flow, thereby reducing the light that directly passes through the water flow.

[0091] Optionally, the guide member may include a water outlet, which is connected to the water outlet 121, and a plurality of ribs are arranged in the water outlet, which disperse the water flow in the water outlet to increase the reflection of light in the water flow and illuminate the water flow. Exemplarily, the plurality of ribs may extend radially of the water outlet.

[0092] In some embodiments, the flow guide may include a filter screen, which is disposed in the water outlet 121 to separate the water flow in the water outlet 121 into multiple water flows, and can also increase the reflection of light in the water flow. The filter screen may be a metal mesh.

[0093] In this embodiment, the lighting lamp includes a water outlet indicator light, a high temperature indicator light and a low temperature indicator light which can be independently activated, and the water outlet indicator light, the high temperature indicator light and the low temperature indicator light have different colors. By setting indicator lights of different colors, different colors can be displayed according to the state of the water outlet structure of the water dispenser and the water outlet temperature, thereby reminding the user to avoid scalding.

[0094] Optionally, the water outlet indicator light may emit a green light, the high temperature indicator light may emit a red light, and the low temperature indicator light may emit a blue light. When the water outlet 121 is in the water outlet state, the water outlet indicator light is activated, and a green light is displayed at the water outlet 121 to remind the user to collect water. When the water temperature at the water outlet 121 is low, there is no risk of scalding to the user, the low temperature indicator light is activated, and a blue light is displayed at the water outlet 121; when the water temperature at the water outlet 121 is high, there is a risk of scalding the user, and the high temperature indicator light is activated, and a red light is displayed at the water outlet 121 to remind the user.

[0095] Embodiment 2

[0096] This embodiment provides a water outlet structure for a water dispenser, which is substantially the same as the water outlet structure for a water dispenser in the first embodiment, except for the specific structure of the water retaining portion.

[0097] like Figure 6-Figure 8 As shown, the water retaining rib 113 and the inner wall of the water outlet box 10 form a curved and extended steam separation channel 116, and the steam separation channel 116 is respectively connected to the hot water inlet 111, the exhaust port 112 and the water outlet 121, and the inner wall of the steam separation channel 116 forms a water retaining portion. By setting the curved and extended steam separation channel 116, the flow direction after entering the steam separation channel 116 from the hot water inlet 111 will change, and the hot water will collide with the inner wall of the steam separation channel 116, so that the steam carried in the hot water is separated, and the steam is discharged upward from the exhaust port 112, and the hot water continues to flow in the water outlet box 10 and flows out from the water outlet 121. The water outlet structure of the water dispenser can separate hot water and steam, improve exhaust, and ensure that there is no steam spray at the water outlet 121, thereby increasing the upper limit of the water outlet temperature of the water outlet 121.

[0098] like Figure 7 As shown, the hot water inlet 111 is in communication with the circumferential outer side wall of the steam separation channel 116 , so that hot water can directly enter the steam separation channel 116 through the hot water inlet 111 .

[0099] In order to facilitate the steam at the separation to be discharged from the exhaust port 112, the water retaining rib 113 is arranged around the exhaust port 112, and a notch 1133 is arranged on the water retaining rib 113, and the notch 1133 is connected to the exhaust port 112. The water retaining rib 113 is arranged around the exhaust port 112, so that the steam separation flow channel 116 is located outside the exhaust port 112, the water retaining rib 113 forms the inner wall of the steam separation flow channel 116, and the notch 1133 on the water retaining rib 113 can be connected to the exhaust port 112, so that the steam can directly enter the exhaust port 112, and the probability of the steam continuing to flow with the hot water is reduced.

[0100] Specifically, the water retaining rib 113 is arranged on the top surface of the water outlet box 10, and at least part of the bottom surface of the water retaining rib 113 is spaced apart from the bottom surface of the water outlet box 10, so as to connect the water outlet 121 and the steam separation channel 116 through the gap between the bottom surface of the water retaining rib 113 and the bottom surface of the water outlet box 10, so that the hot water after the steam is separated can flow to the water outlet 121 through the gap between the bottom surface of the water retaining rib 113 and the bottom surface of the water outlet box 10.

[0101] like Figure 8 As shown, the exhaust port 112 is arranged on the top surface of the water outlet box 10, and the hot water inlet 111 is arranged on the side of the upper end of the water outlet box 10. The hot water inlet 111 is connected to the upper part of the steam separation channel 116, so that after the hot water collides with the inner wall of the steam separation channel 116, the hot water flows to the lower end of the steam separation channel 116 under the action of gravity, and the steam at the separation point flows upward according to its own characteristics, and enters the exhaust port 112 through the notch 1133 after flowing along the steam separation channel 116.

[0102] The water outlet 121 is arranged at the lower end of the water outlet box 10. It can be understood that the steam separation channel 116 is arranged at the top of the water outlet box 10, and the bottom surface of the water retaining rib 113 is spaced from the bottom surface of the water outlet box 10, so that the bottom end of the steam separation channel 116 is connected with the water outlet 121, and the hot water flowing in the steam separation channel 116 can flow to the water outlet 121 at the lower end of the water outlet box 10 under the action of its own gravity, and the steam has a small density and will automatically flow upward, further improving the separation effect of steam and hot water.

[0103] To further improve the separation effect of steam and hot water, at least part of the steam separation channel 116 is an arc segment extending along an arc line. The extension direction of the arc segment changes continuously and has no edges and corners, which can fully collide with the hot water, thereby separating the steam in the hot water and improving the gas-liquid separation effect.

[0104] Optionally, the flow direction of hot water in the hot water inlet 111 can be tangent to the inner wall of the steam separation channel 116, so that the hot water can flow better along the inner wall of the steam separation channel 116, thereby improving the guiding effect of the steam separation channel 116 on the hot water.

[0105] In this embodiment, Figure 7 As shown, the steam separation channel 116 includes two arc segments and two straight segments, and the hot water inlet 111 is connected to one end of one of the arc segments. After the hot water enters the steam separation channel 116, it first flows along the arc segment to achieve the purpose of fully separating the steam. In other embodiments, the steam separation channel 116 can be annular, that is, the inner wall of the steam separation channel 116 is a curved surface, which can further improve the steam separation effect.

[0106] Furthermore, the hot water inlet 111 is tangent to the circumferential outer wall of the arc segment to guide the hot water to flow along the circumferential outer wall of the arc segment, which is beneficial to improving the steam separation effect.

[0107] Because the water in the hot water inlet 111 has a certain flow rate, when the hot water enters the steam separation flow channel 116, it is affected by inertia and gravity and flows approximately in a spiral direction. It can be understood that the longer the path of the hot water flowing in the steam separation flow channel 116 before falling to the bottom of the water outlet box 10, the better the steam separation effect. To this end, in this embodiment, the two arc segments of the steam separation flow channel 116 are connected by a straight line segment, so that the steam separation flow channel 116 can be long and strip-shaped. On the basis of not increasing the diameter of the arc segment, the total length of the steam separation flow channel 116 is extended, thereby extending the flow path of the hot water before it falls to the bottom of the water outlet box 10, which is conducive to improving the gas-liquid separation effect.

[0108] In this embodiment, Figure 7 As shown, a groove is provided on the top inner wall of the water outlet box 10, and the exhaust port 112 is connected to the bottom surface of the groove; a water retaining rib 113 is provided in the groove and around the exhaust port 112, and the water retaining rib 113 and the inner wall of the groove form a steam separation channel 116, and the steam separation channel 116 is provided around the exhaust port 112 in a circumferential direction.

[0109] In order to increase the flow path of hot water in the steam separation channel 116, one end of the water retaining rib 113 is connected to the inner wall of the groove, and the other end forms a notch 1133, and the notch 1133 and the hot water inlet 111 are respectively located on opposite sides of the water retaining rib 113. Through this arrangement, the steam entering the steam separation channel 116 can flow from one end of the steam separation channel 116 connected to the hot water inlet 111 to the other end of the steam separation channel 116, and then enter the exhaust port 112 through the notch 1133, thereby extending the flow path of water and steam and improving the gas-liquid separation effect.

[0110] In this embodiment, the water outlet box 10 includes a shell, and the shell includes an upper cover 11 and a bottom shell 12 connected to each other. The exhaust port 112, the hot water inlet 111 and the water retaining rib 113 are all arranged on the upper cover 11, and the normal temperature water inlet 122 and the water outlet 121 are arranged on the bottom surface of the bottom shell 12. Compared with the water outlet box 10 of the first embodiment, the upper cover is omitted in the water outlet box 10 of the present embodiment, and only one cavity is arranged in the water outlet box 10. By arranging the hot water inlet 111 at the top of the water outlet box 10 and the normal temperature water inlet 122 at the bottom of the water outlet box 10, the distance between the two can be enlarged, and the hot water and normal temperature water channels can be separated.

[0111] In some embodiments, the water outlet box 10 may also adopt the structure in the first embodiment, that is, an upper cavity and a lower cavity are formed in the water outlet box 10 by adding an upper cover.

[0112] In this embodiment, the water outlet structure of the water dispenser also includes a lighting component 20, which is arranged on the water outlet box 10. On the one hand, the lighting component 20 can sterilize the water and improve the hygiene of drinking water. On the other hand, it can illuminate the water in the water outlet box 10 to avoid scalding, spilling, etc. caused by dim light at the water outlet 121 when the user receives water.

[0113] Specifically, the lighting assembly 20 includes a lamp holder 21 and a lamp group 22. A mounting hole is provided on the water outlet box 10, and the mounting hole is located directly above the water outlet 121. The lamp holder 21 is disposed in the mounting hole. The lamp group 22 includes a circuit board and at least one of a lighting lamp and an ultraviolet lamp disposed on the circuit board. The circuit board is disposed on the lamp holder 21, and the lighting lamp and the ultraviolet lamp are disposed on a side surface of the circuit board facing the inside of the water outlet box 10, so that the light emitted by the lighting lamp and the ultraviolet light emitted by the ultraviolet lamp are both emitted into the water in the water outlet box 10, and the ultraviolet light disinfects the water. The light emitted by the lighting lamp and the ultraviolet light is used to illuminate the water, so that the outlet water flow is bright, thereby illuminating the vicinity of the water outlet 121, and avoiding scalding or spilling of water when the user receives water.

[0114] Compared with setting a lighting lamp outside the water outlet box 10 and around the water outlet 121, in this embodiment, the lighting lamp and the ultraviolet lamp are integrated on the circuit board, and the water outlet 121 is illuminated by illuminating the water flow, which is conducive to simplifying the structure.

[0115] Since water has a high light transmittance, most of the light is directly transmitted through it, and only a small part of the light can be absorbed and scattered by the water, resulting in low brightness of the water. In order to improve the degree of illumination of the water by the lighting lamp, the lighting assembly 20 also includes a guide member, which is arranged at the water outlet 121 and is used to break up the water flow so that the light is reflected multiple times in the water flow, thereby reducing the light that directly passes through the water flow.

[0116] Optionally, the guide member may include a water outlet, which is connected to the water outlet 121, and a plurality of ribs are arranged in the water outlet, which disperse the water flow in the water outlet to increase the reflection of light in the water flow and illuminate the water flow. Exemplarily, the plurality of ribs may extend radially of the water outlet.

[0117] In some embodiments, the flow guide may include a filter screen, which is disposed in the water outlet 121 to separate the water flow in the water outlet 121 into multiple water flows, and can also increase the reflection of light in the water flow. The filter screen may be a metal mesh.

[0118] In this embodiment, the lighting lamp includes a water outlet indicator light, a high temperature indicator light and a low temperature indicator light which can be independently activated, and the water outlet indicator light, the high temperature indicator light and the low temperature indicator light have different colors. By setting indicator lights of different colors, different colors can be displayed according to the state of the water outlet structure of the water dispenser and the water outlet temperature, thereby reminding the user to avoid scalding.

[0119] Optionally, the water outlet indicator light may emit a green light, the high temperature indicator light may emit a red light, and the low temperature indicator light may emit a blue light. When the water outlet 121 is in the water outlet state, the water outlet indicator light is activated, and a green light is displayed at the water outlet 121 to remind the user to collect water. When the water temperature at the water outlet 121 is low, there is no risk of scalding to the user, the low temperature indicator light is activated, and a blue light is displayed at the water outlet 121; when the water temperature at the water outlet 121 is high, there is a risk of scalding the user, and the high temperature indicator light is activated, and a red light is displayed at the water outlet 121 to remind the user.

[0120] like Figure 8 As shown, the lighting assembly 20 further includes a lampshade 23, which is covered on the lamp holder 21, and the lamp group 22 is located in the lampshade 23. By providing the lampshade 23, water can be prevented from directly contacting the lighting lamp, the ultraviolet lamp and the circuit board, so as to improve the safety of use.

[0121] Furthermore, a sealing member 24 is provided between the lamp holder 21 and the water outlet box 10 . The sealing member 24 may be a sealing ring to improve the sealing performance of the water outlet box 10 and prevent the water outlet box 10 from leaking.

[0124] In this embodiment, no water retaining ribs are provided in the water outlet box 10, and the inner wall of the water outlet box 10 forms a water retaining portion. Specifically, the water outlet box 10 has a side wall that is arranged opposite to the hot water inlet 111, and the distance between this part of the inner wall and the hot water inlet 111 is small, so that the hot water flowing into the water outlet box 10 from the hot water inlet 111 can hit the inner wall of the water outlet box 10 to separate the steam. In this embodiment, it is not necessary to provide a water retaining rib in the water outlet box 10, and it is only necessary to adjust the distance between the hot water inlet 111 and part of the inner wall of the water outlet box 10. The structure is simple, which is conducive to reducing costs.
