[0036] See also Figure 1-Figure 7 As shown, a control valve with overflow function of the present invention cooperates with a water tank 8, including a valve body 1, a valve core 2 and an operating member 3. The valve body 1 is installed at the installation port 811 set at the top of the water tank side wall 81, and the valve body 1 is provided with a valve core seat 11, an overflow chamber 12, a water outlet 18 connected to the overflow chamber 12, and an overflow port 13 located on the side of the valve body 1 and connected to the overflow chamber 12 and the inside of the water tank. The valve core 2 is installed horizontally on the valve core seat 11. Specifically, the valve core 2 is limitedly connected to the valve core seat 11 by a clamping nut 21. The driving part of the valve core 2 faces the inside of the water tank and is connected to the operating member 3 by a set screw 31. The operating member 3 blocks the overflow port 13. The above-mentioned water tank side wall 81 is specifically the rear side wall of the water tank, but it is not limited thereto. In other embodiments, the installation port 811 of the valve body 1 can be set on the left side wall or the right side wall of the water tank according to actual needs.

[0037] As a preferred embodiment, the bottom surface of the overflow chamber 12 is provided with a drainage structure to allow the water entering the overflow chamber 12 to be quickly discharged to the water outlet 18, thereby preventing the water from remaining in the overflow chamber 12 for a long time and causing odor and bacterial growth. The drainage structure includes a diversion slope and / or a diversion groove. Figure 2 As shown, the drainage-aiding structure includes a bottom surface of the overflow chamber 12 provided with a guide groove 14 extending along the axial direction of the valve core 2, one end of the guide groove 14 leads to the overflow port 13, and the water outlet 18 is located at the other end of the guide groove 14, and the water outlet 18 faces downward and is connected to the overflow pipe 9. The bottom surface of the overflow chamber 12 located on the left and right sides of the guide groove 14 is respectively formed with guide slopes 19 inclined to the guide groove 14. In this way, it can be ensured that the overflow water and the water splashed into the overflow chamber 12 by the user during the cleaning process can be quickly drained away. In other embodiments, the drainage-aiding structure includes a guide slope, which extends to the entire bottom surface of the overflow chamber, and the high end of the guide slope leads to the overflow port, and the low end of the guide slope leads to the water outlet, so that the water entering from the overflow port can flow quickly along the guide slope toward the water outlet, thereby being quickly drained away.

[0038] The overflow chamber 12 is located outside the valve core seat 11, and the driving part of the valve core 2 is located within the range of the overflow port 13, so that the volume of the overflow chamber 12 is large, the overflow area of ​​the overflow port 13 is large, and the overflow capacity is strong. In particular, in the present embodiment, the valve core seat 11 is provided in plurality, and the plurality of valve core seats 11 are arranged in the horizontal direction and connected one by one; the valve core 2 is provided in plurality, and the plurality of valve cores 2 correspond one-to-one to the plurality of valve core seats 11; the operating member 3 is also provided in plurality, and the plurality of operating members 3 correspond one-to-one to the plurality of valve cores 2. In this way, the volume of the overflow chamber 12 and the water flow area of ​​the overflow port 13 can be further increased, so that the water flow area of ​​the overflow port 13 of the present invention is larger than the water flow area of ​​the traditional overflow port 13, and the overflow capacity is significant. Specifically, the valve core seat 11, the valve core 2 and the operating member 3 of the present invention are respectively exemplified in three, but are not limited thereto.

[0039] The valve body 1 is sealed and connected to the outer side of the water tank side wall 81, the overflow port 13 is connected to the installation port 811, the operating member 3 is arranged in the installation port 811, and an overflow gap 812 suitable for the operation member 3 to move is formed between the operating member 3 and the inner wall of the installation port 811. The width of the overflow gap 812 between the operating member 3 and the lower end inner wall of the installation port 811 is much larger than the width of the overflow gap 812 between the operating member 3 and the upper end inner wall of the installation port 811, so that the overflow gap 812 between the operating member 3 and the upper end inner wall of the installation port 811 is not easy to be noticed by the user, while the overflow gap 812 between the operating member 3 and the lower end inner wall of the installation port 811 is larger, and the overflow capacity is stronger, which can meet the overflow demand. At the same time, the overflow gap 812 between the operating member 3 and the lower end inner wall of the installation port 811 is blocked by the operating member 3 and is not easy to be observed by the user, especially. In this embodiment, the operating member 3 is a seesaw button structure, so that the protruding structure of the operating member 3 has a better shielding effect on the overflow gap 812 and the overflow port 13. In other embodiments, one end of the valve body provided with the overflow port is sleeved in the mounting port of the side wall of the water tank. At this time, an overflow gap communicating with the overflow port is formed between the operating member and the inner side surface of the side wall of the water tank.

[0040] The top of the water tank side wall 81 is provided with a water tank countertop 82, and the top of the valve body 1 is open to form an opening 15 connected to the overflow chamber 12, and the edge of the opening 15 facing the water tank side wall 81 and the top edge of the overflow port 13 penetrate each other. The remaining edge of the overflow port 13 is sealed and attached to the outer side of the water tank side wall 81 by the first sealing member 41, and the remaining edge of the opening 15 is sealed and attached to the lower surface of the water tank countertop 82 by the second sealing member 42. In this way, the installation height of the valve body 1 can be the highest, so that the operating member 3 is in the highest position, and the user's comfort in operation can be improved.

[0041] The overflow port 13 and the opening 15 at the top of the valve body 1 are square openings, respectively. Therefore, the remaining edges of the overflow port 13 are the left edge, right edge and lower edge of the overflow port 13, and these three edges are linear edges. Similarly, the remaining edges of the opening 15 are the left edge, right edge and one end edge away from the side wall 81 of the water tank, and these three edges are also linear edges. The first sealing member 41 is fitted on the remaining edges of the overflow port 13, and the second sealing member 42 is fitted on the remaining edges of the opening 15, and the two ends of the first sealing member 41 are connected one by one with the two ends of the second sealing member 42, so that the first sealing member 41 and the second sealing member 42 form an integrated sealing sleeve 4, and therefore, the sealing sleeve 4 is a special-shaped structure.

[0042] At least one first connecting member 83 is provided on the outer side of the water tank side wall 81, and the first connecting member 83 is threadedly connected with a first screw 5, and the tail of the first screw 5 abuts against the valve body 1 to press the first sealing member 41 against the outer side of the water tank side wall 81. Specifically, the first connecting member 83 is fixed to the outer side of the water tank side wall 81 by welding, and the number of the first connecting members 83 is two, but not limited to this, and the two first connecting members 83 are distributed on the left and right; the tail of the first screw 5 faces upward, and the valve body 1 is provided with a first inclined surface 16 corresponding to the tail of the first screw 5, the lower end of the first inclined surface 16 is close to the water tank side wall 81, and the upper end is away from the water tank side wall 81, and the tail of the first screw 5 abuts against the first inclined surface 16, as shown in FIG. Figure 5 As shown, in this way, the upward locking force of the first screw 5 can be converted into a forward locking force, ensuring the sealing between the first sealing member 41 and the outer side of the water tank side wall 81. The tail of the first screw 5 is provided with a spherical surface to prevent the tail of the first screw 5 from scratching the first inclined surface 16. Since the water tank side wall 81 is the rear side wall of the water tank, in this embodiment, the side facing the water tank side wall 81 is the front, and the opposite side is the rear.

[0043] At least one second connecting member 84 is provided on the lower surface of the sink countertop 82, and the valve body 1 is provided with a fixing portion 17 corresponding to the second connecting member 84, and the fixing portion 17 is locked to the second connecting member 84 by a second screw 6, so as to press the first sealing member 41 to the outer side of the sink side wall 81, and press the second sealing member 42 to the lower surface of the sink countertop 82. Specifically, the second connecting member 84 can be fixed to the lower surface of the sink countertop 82 by welding or the like, and the number of the second connecting members 84 is three, but not limited thereto.

[0044] The fixing portion 17 is provided with a through hole 171 for the second screw 6 to pass upward. The through hole 171 is a flat hole whose length direction is consistent with the axial direction of the valve core 2. Specifically, the through hole 171 is an elliptical hole, but it is not limited thereto. In other embodiments, the through hole 171 is a waist-shaped hole, etc. The fixing portion 17 is provided with a second inclined surface 172 at the lower end corresponding to the through hole 171. The lower end of the second inclined surface 172 is close to the side wall 81 of the water tank, and the high end is away from the side wall 81 of the water tank. The present invention also includes an inclined block 7 that is slidably fitted on the second inclined surface 172. The screw rod of the second screw 6 passes through the inclined block 7 and the through hole 171 upward in sequence, and is threadedly connected to the second connecting member 84, such as Figure 5 The through hole 171 on the fixing part 17 is set as a flat hole, so that when the second screw 6 is tightened, the valve body 1 can move forward to press the first sealing member 41; the inclined block 7 can slide forward and backward and move up and down, and the second screw 6 is tightened upward, and the upward force is decomposed into a forward locking force and an upward locking force, so that the first sealing member 41 is tightly attached to the outer side of the water tank side wall 81, and the second sealing member 42 is tightly attached to the lower surface of the water tank countertop 82, thereby ensuring the sealing between the valve body 1 and the water tank.

[0045] A control valve with overflow function of the present invention is installed in a water tank 8. When the water tank 8 overflows, water flows into the overflow cavity 12 through the overflow gap 812 between the operating member 3 and the inner wall around the installation port 811 and the overflow port 13 in sequence, and flows to the water outlet 18 under the guidance of the guide groove 14 and the guide slopes 19 on both sides, and finally discharged to the downpipe group installed at the bottom of the water tank through the overflow pipe 9, such as Figure 7 As shown, the arrows in the figure indicate the direction of water flow.

[0046] Therefore, the control valve of the present invention integrates an overflow function, and its operating member 3 can block the overflow port 13 whether it is opened or closed, and the user cannot directly see the overflow port 13, so that the appearance of the sink 8 does not have a conventional overflow port. In particular, the operating member 3 is located at the highest position below the sink countertop 82, and the operating member 3 is set as a seesaw button structure. The height of a general kitchen countertop is 800mm. According to ergonomics and actual tests, the raised operating member 3 can block the overflow gap 812 below the operating member 3. When people use it normally, their vision is blocked and they cannot directly see the overflow gap 812 below the operating member 3. Therefore, the operating member 3 of the present invention can play a role in hiding the overflow port 13 and the overflow gap 812, making the internal appearance of the sink 8 more concise and beautiful. In addition, the present invention can not only ensure overflow, but also conform to ergonomics to the greatest extent and be comfortable to use.

[0047] See also Figure 1-Figure 7 As shown, an integrated water tank of the present invention comprises a water tank 8 and also comprises a control valve with overflow function as described above.

[0048] The integrated sink of the present invention also includes a temperature control knob 20 arranged on the sink countertop 82 and a temperature control valve core 30 arranged under the sink countertop 82 and connected to the temperature control knob 20. The temperature control valve core 30 is a constant temperature valve core, and its water outlet end is connected to the water inlet end of each of the above-mentioned valve cores 2. Each of the above-mentioned valve cores 2 is a switch valve core.

[0049] The integrated water sink of the present invention also includes a flying rain water outlet module 50 arranged on the side wall 81 of the water sink and a water outlet pipe assembly 40 arranged on the water sink table 82. The water inlet ends of the water outlet pipe assembly 40 and the flying rain water outlet module 50 are respectively connected to the water outlet ends of the corresponding valve core 2 so that the corresponding valve core 2 can control whether water is discharged or not.
