Description

Technical Field

[0001] The present invention relates to the field of kitchen and bathroom, and particularly to a control system for automatically controlling the water inlet and drainage of a sink.

Background Art

[0002] The sink used in the household kitchen is a tank for holding water and used for washing tableware and ingredients to be processed. For a household kitchen, the sink is the heart of the kitchen. According to statistics, among various kitchen utensils, the sink has the highest usage rate. Especially during the preparation and cleaning work before and after meals, more than 65% of the time is directly related to the sink. And modern people's demand for a healthy, environmentally friendly, safe and intelligent kitchen is constantly expanding, and the demand for upgrading and replacing kitchen utensils is particularly urgent. Therefore, it is very important to select a sink with good performance, clean and easy to control for building a comfortable and warm kitchen.

[0003] However, in the process of using the existing sink, it is rather troublesome. As is well known, the sink is mainly composed of a sink body and a drainer. The drainer is installed at the bottom drain of the sink body. On the one hand, it is to seal the sink body to facilitate storing water in the sink body. On the other hand, it is to connect the channel between the sink body and the drain pipe. When the water in the sink body is polluted (the water left after washing fruits and vegetables or tableware), it is necessary to manually open the drainer to drain the water in the sink body into the drain pipe. However, such an operation requires the user to reach into the water to pull out or insert the drainer. Especially in winter or when the water in the sink is relatively dirty, the operation is very inconvenient. Therefore, in the existing sink, the control in the using process is rather cumbersome and the operation is rather troublesome, not to mention intelligent control. Especially, most of the drain openings of the drainer still directly operate the valve cover inside manually to control the opening and closing of the drain opening, which is not only unhygienic, but also the whole process is complex to operate. Therefore, there is still a large room for improvement in the existing kitchen sink.

Summary of the Invention

[0004] The present invention provides a control system for automatically controlling the water inlet and drainage of a sink, which realizes the automatic comprehensive control of the water supply of the faucet and the drainage of the cavity of the sink body through an integrally integrated switch control part, is convenient to operate, has high reliability, and saves the operation space on the sink countertop.

[0005] The technical solution adopted by the present invention to solve its technical problems is:

[0006] A control system for automatically controlling the water inlet and drainage of a sink, including a faucet, a sink body and a switch control part. At least one cavity for storing water is provided on the sink body. A drain opening for draining water is provided at the bottom of each cavity on the sink body. The switch control part is installed on the sink body and controls the closing and opening of the hot water inlet pipe or / and the cold water inlet pipe to supply water to the faucet.

[0007] At the drain outlet of each cavity on the water tank body, a drainer connected to the drain pipe and used to control the opening and closing of the drain outlet is respectively provided. A sealing cover for opening and closing the drain outlet is arranged in each drainer.

[0008] On the switch control part, a faucet valve body switch for controlling the closing or opening of the hot water inlet pipe or / and the cold water inlet pipe is provided. On the switch control part, a drain control switch for respectively controlling the opening or closing of the sealing cover in each drainer to open or close the drain outlet is also provided.

[0009] Between the drain control switch and each drainer, a wire-controlled pulling steel wire rope and a touch control part for driving the opening or closing of the sealing cover of each drain outlet are respectively provided. The touch control parts are respectively arranged at the bottom of each drainer and touch and drive the opening or closing of the sealing cover of the drain outlet. One end of each wire-controlled pulling steel wire rope is connected to the drain control switch, and the other end of each wire-controlled pulling steel wire rope is respectively connected to the touch control part in each drainer and drives the touch control part to touch the sealing cover in a linkage manner when the drain control switch respectively pulls each wire-controlled pulling steel wire rope.

[0010] Further, the faucet valve body switch and the drain control switch on the switch control part are integrally installed and connected.

[0011] The faucet valve body switch includes a cylindrical valve core body and a faucet switch knob installed at the top end of the valve core body. A pipeline connection end cover communicated with the hot water inlet pipe or / and the cold water inlet pipe respectively is arranged at the bottom end of the valve core body.

[0012] The drain control switch includes a drain switch knob, a guiding sliding sleeve and at least one lifting pull rod. The valve core body is respectively provided with guiding holes slidably matched with each lifting pull rod along the axial direction. A stop push rod extending radially from the guiding hole along the valve core body is connected to the top end of the lifting pull rod. A sliding groove communicated with the guiding hole and convenient for the stop push rod on the lifting pull rod to slide therein is provided in the corresponding radial direction of the valve core body. The guiding sliding sleeve is installed inside the drain switch knob and sleeved on the valve core body together. An inclined arc surface groove for slidably contacting with the stop push rods on all the lifting pull rods and pulling the lifting pull rods to move up and down when the drain switch knob drives the guiding sliding sleeve to rotate synchronously is arranged on the outer wall of the guiding sliding sleeve along the axial direction.

[0013] The lower end of each lifting pull rod is respectively connected to the wire-controlled pulling steel wire rope corresponding to each drainer and jacks up the sealing cover through the linkage touch control part to open the drain outlet at the bottom of the drainer.

[0014] Further, the faucet valve body switch and the drain control switch on the switch control part are integrally installed and connected.

[0015] Further, the faucet valve body switch includes a cylindrical valve core body and a faucet switch knob installed at the top end of the valve core body. A pipeline connection end cover communicating with the hot water inlet pipe and the cold water inlet pipe respectively is arranged at the bottom end of the valve core body.

[0016] The drain control switch includes a drain switch knob, a guide sliding sleeve, and two lifting pull rods. The drain switch knob uses a single control handle. Two guide holes slidably matched with the lifting pull rods are respectively arranged on the valve core body along the axial direction. A stop push rod extending radially from the guide hole along the valve core body is connected to the top end of the lifting pull rod. A chute communicating with the guide hole and facilitating the sliding of the stop push rod on the lifting pull rod therein is arranged radially on the corresponding valve core body. The guide sliding sleeve is installed inside the drain switch knob and sleeved on the valve core body together. An inclined arc surface groove with symmetric openings is axially formed on the outer wall of the circumferential direction of the guide sliding sleeve. The inclined arc surface groove is in sliding contact with the stop push rods on the two lifting pull rods respectively. When the drain switch knob drives the guide sliding sleeve to rotate synchronously, when the guide sliding sleeve rotates clockwise, the inclined surface on the right side of the inclined arc surface groove pushes the lifting pull rod on the right side of the valve core body to rise. When the guide sliding sleeve rotates counterclockwise, the inclined surface on the left side of the inclined arc surface groove pushes the lifting pull rod on the left side of the valve core body to rise.

[0017] The lower ends of the two lifting pull rods are respectively connected to the wire-controlled pulling steel wires corresponding to each drainer in the two cavities of the sink body. When the drain switch knob and the guide sliding sleeve are in the middle position between the two lifting pull rods, the drain openings corresponding to the two cavities of the sink body are controlled to be closed simultaneously. When the drain switch knob and the guide sliding sleeve rotate clockwise or counterclockwise, one of the two lifting pull rods is pulled to act, and the corresponding wire-controlled pulling steel wire drives the touch control member to respectively jack up the sealing cover of the drainer to control the opening of the drain opening of one of the two cavities of the sink body.

[0018] Further, the faucet valve body switch includes a cylindrical valve core body and a faucet switch knob installed at the top end of the valve core body. A pipeline connection end cover communicating with the hot water inlet pipe and the cold water inlet pipe respectively is arranged at the bottom end of the valve core body.

[0019] The drain control switch includes an upper handle drain switch knob, a lower handle drain switch knob, an upper side guide sliding sleeve, a lower side guide sliding sleeve, an upper handle lifting pull rod, and a lower handle lifting pull rod. Guide holes slidably matched with the upper handle lifting pull rod and the lower handle lifting pull rod are respectively arranged on the valve core body along the axial direction.

[0020] The top ends of the upper handle lifting pull rods are respectively connected with upper handle stop push rods extending radially from the guide holes along the valve core body. The top ends of the lower handle lifting pull rods are respectively connected with lower handle stop push rods extending radially from the guide holes along the valve core body. Corresponding radial directions of the valve core body are respectively provided with chutes communicating with their respective guide holes to facilitate the sliding of the upper handle stop push rods or the lower handle stop push rods therein.

[0021] The upper side guide sliding sleeve is installed inside the lower water switch knob of the upper handle and is sleeved on the upper side of the valve core body together. The lower side guide sliding sleeve is installed inside the lower water switch knob of the lower handle and is sleeved on the upper side of the valve core body below the upper side guide sliding sleeve on the lower handle.

[0022] Axially along the outer circumferential walls of the upper side guide sliding sleeve and the lower side guide sliding sleeve, one-way inclined arc-shaped grooves are respectively formed in a one-way inclined manner. The one-way inclined arc-shaped grooves are respectively in sliding contact with the upper handle stop push rod on the upper handle lifting pull rod and the lower handle stop push rod of the lower handle lifting pull rod.

[0023] The lower water switch knob of the upper handle drives the upper side guide sliding sleeve to rotate synchronously. The lower water switch knob of the lower handle drives the lower side guide sliding sleeve to rotate synchronously. When the upper side guide sliding sleeve and the lower side guide sliding sleeve rotate clockwise respectively, the inclined surfaces of the one-way inclined arc-shaped grooves respectively push the upper handle lifting pull rod and the lower handle lifting pull rod to rise respectively. When the upper side guide sliding sleeve and the lower side guide sliding sleeve rotate counterclockwise respectively, the inclined surfaces of the one-way inclined arc-shaped grooves respectively release the stop push, and then the upper handle lifting pull rod and the lower handle lifting pull rod respectively descend and reset.

[0024] The lower ends of the upper handle lifting pull rod and the lower handle lifting pull rod are respectively connected with the wire-controlled pulling steel wires corresponding to each drainer in two cavities of the sink body. The lower water switch knob of the upper handle, the upper side guide sliding sleeve and the upper handle lifting pull rod independently control the closing and opening of the drain port of the drainer corresponding to one cavity of the sink body through the wire-controlled pulling steel wire. The lower water switch knob of the lower handle, the lower side guide sliding sleeve and the lower handle lifting pull rod independently control the closing and opening of the drain port of the drainer corresponding to the other cavity of the sink body through the wire-controlled pulling steel wire. The lower water switch knob of the upper handle and the lower water switch knob of the lower handle are independently and non-associatedly connected and controlled for the drain ports of the drainers corresponding to their respective cavities of the sink body.

[0025] Further, the drainer is in a cylindrical shape. A circular sealing cover is inserted on the upper side of the drain port of the cylindrical drainer. A central positioning shaft extends downward from the center of the bottom end of the sealing cover. A central guide hole is provided at the center of the corresponding drain port of the drainer, which is matched with the central positioning shaft to facilitate the insertion of the sealing cover to seal the entire drain port and the lifting of the sealing cover to open the drain port.

[0026] The touch control member is an L-shaped deflector. A receiving cavity for accommodating the L-shaped deflector is formed below the central guiding hole of the cylindrical drainer. The corner of the L-shaped deflector is hinged to the inner wall of the cylindrical drainer, and a hinge fulcrum shaft for hinging and fixing the L-shaped deflector extends into the receiving cavity from the corresponding inner wall of the cylindrical drainer.

[0027] A side guiding through hole is provided on the side wall of the cylindrical drainer corresponding to the upper side of the L-shaped deflector, which facilitates the direct insertion of the wire-controlled pulling steel wire rope and is straightly connected and fixed to the upper side of the L-shaped deflector. A pushing block for contacting the central positioning shaft at the lower end of the bottom of the sealing cover is provided at the lower end of the L-shaped deflector corresponding to the lower side of the central guiding hole. The L-shaped deflector deflects at a certain angle around the hinge fulcrum shaft under the pulling of the wire-controlled pulling steel wire rope, contacts the end of the central positioning shaft, and pushes the sealing cover to rise to open the drain opening of the drainer.

[0028] Further, at least one diversion port for facilitating the discharge of water in the cavity of the sink body is provided at the drain opening in the circumferential direction of the central guiding hole; the L-shaped deflector is installed in the receiving cavity below the central guiding hole while avoiding the diversion port, and a shielding cover is provided in the circumferential direction of the corresponding central guiding hole to cover the upper side of the L-shaped deflector, preventing the water in the cavity from directly flushing the L-shaped deflector or preventing foreign matters in the water from winding around the L-shaped deflector to block the drain opening.

[0029] Further, a leakage blocking cover for facilitating the sliding of the wire-controlled pulling steel wire rope and sealing the side guiding through hole to prevent the drainer from leaking water is provided on the outer wall of the cylindrical drainer corresponding to the side guiding through hole.

[0030] Further, a guide connection cover communicating with the drain pipe is threadedly connected to the bottom end of the drainer.

[0031] The beneficial effects of the present invention are as follows:

[0032] In the present invention, a faucet valve body switch for controlling the water supply of the faucet and a drain control switch for controlling the drainage of each cavity of the sink body are respectively arranged on the integrally integrated switch control part, realizing the automatic comprehensive control of water supply and drainage. Compared with various control switches installed on the sink tabletop in the prior art, the control space on the sink tabletop is effectively saved, the installation interfaces are reduced, the pollution of the sink tabletop is reduced, and the cleanliness of the sink tabletop is effectively increased.

[0033] The linkage control assembly that controls the opening or closing of the drain port of the sealing cover of each drainer is composed of a water discharge control switch, a wire-controlled pulling steel wire rope, and a touch control member. This linkage control assembly realizes the traction sliding of the wire-controlled pulling steel wire rope according to the wire rope braking system that controls the wheel stop on the bicycle, which is convenient to operate and facilitates the automatic drainage of each cavity of the sink body. Especially in winter or when the water in the sink is relatively dirty, it can avoid freezing the hands or soiling the hands, improve the comfort of user use, and ensure the cleanliness and tidiness during the use process. Moreover, one end of the wire-controlled pulling steel wire rope is directly connected and fixed to the end of the lifting pull rod of the water discharge control switch, and the other end of the wire-controlled pulling steel wire rope passes straight through the side guide hole on the side wall of the cylindrical drainer and is directly connected and fixed to the upper side of the L-shaped deflector. The overall connection structure is simple, effectively preventing the wire-controlled pulling steel wire rope from knotting or jamming, effectively improving the reliability of the operation of the water discharge control switch, and preventing the sealing cover at the drain port of the drainer from not being able to be opened or not being tightly closed.

[0034] At the same time, since the touch control member is an L-shaped deflector, the central positioning shaft on the lower side of the bottom end of the sealing cover is in contact with the pushing block at the lower end of the L-shaped deflector. In this way, according to needs, the sealing cover can also be manually controlled to open and close the drain port of the drainer, realizing the free switching between the automatic control mode and the manual control mode, and improving the wide applicability during the use process of the sink.

[0035] In addition, the L-shaped deflector is installed in the accommodation cavity below the central guide hole while avoiding the diversion port, and a shielding cover that seals the upper side of the L-shaped deflector is provided circumferentially around the corresponding central guide hole. The diversion port at the drain port is set structurally, and the shielding cover prevents the water body in the sink cavity from directly flushing the L-shaped deflector or foreign objects in the water body from winding around the L-shaped deflector and blocking the drain port during the use process of the drainer and the corresponding sink, further improving the reliability of the drain port of the drainer.

Detailed implementation manners

[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0054] Embodiment 1

[0055] A control system for automatically controlling the water inlet and drainage of a water tank, as Figures 1 to 12As shown, it includes a faucet 1, a sink body 2 and a switch control unit 3. The sink body 2 is provided with two cavities 20 for storing water. A drain port 4 for draining water is provided at the bottom of each cavity 20 on the sink body 2. The switch control unit 3 is installed on the sink body 2 and controls the closing and opening of the hot water inlet pipe 5 and the cold water inlet pipe 6 to supply water to the faucet 1. Of course, it can also be different from this embodiment. The sink body is provided with a cavity for storing water, and the bottom of the cavity on the sink body is provided with a drain port for draining water. The switch control unit is installed on the sink body and controls the closing and opening of the hot water inlet pipe or the cold water inlet pipe, or a single water source to supply water to the faucet.

[0056] like Figures 1 to 10 As shown, the drain outlet 4 of each cavity 20 on the sink body 2 is also provided with a drain 7 connected to the sewer pipe and used to control the opening and closing of the drain outlet 4, and each drain 7 is provided with a sealing cover 8 for opening and closing the drain outlet 4; the switch control part 3 is provided with a faucet valve body switch 30 for controlling the closing or opening of the hot water inlet pipe 5 and the cold water inlet pipe 6, and a drain control switch 31 for controlling the sealing cover 8 in each drain 7 to open or close the drain outlet 4; wherein, the faucet valve body switch 30 and the drain control switch 31 on the switch control part 3 are integrally installed and connected.

[0057] Continue as Figures 1 to 10 As shown, a wire-controlled pulling steel wire rope 9 and a touch control part 10 for driving each sealing cover 8 to open or close the drain outlet 4 are respectively provided between the drain control switch 31 and each drain 7. The touch control part 10 is respectively arranged at the bottom of each drain 7 and contacts the sealing cover 8 to open or close the drain outlet 4. One end of each wire-controlled pulling steel wire rope 9 is connected to the drain control switch 31, and the other end of each wire-controlled pulling steel wire rope 9 is respectively connected to the touch control part 10 in each drain 7, and the drain control switch 31 pulls each wire-controlled pulling steel wire rope 9 to drive the touch control part 10 to touch the sealing cover 8.

[0058] like Figure 9 and Figure 10 As shown, the faucet valve body switch 30 includes a cylindrical valve core body 300 and a faucet switch knob 301 installed on the top of the valve core body 300, and the bottom end of the valve core body 300 is provided with a pipeline connection end cover 302 respectively connected to the hot water inlet pipe 5 and the cold water inlet pipe 6 and a positioning ring 303 for installing and fixing the water control switch 31; of course, a cavity 20 for storing water is provided on the corresponding sink body 2, and the bottom end of the valve core body 300 is provided with a pipeline connection end cover respectively connected to the hot water inlet pipe 5 or the cold water inlet pipe 6, or a single water source.

[0059] Continue as Figure 9 and Figure 10As shown in the figure, the water drainage control switch 31 includes a water drainage switch knob 310, a guiding sliding sleeve 311 and two lifting pull rods 312. The water drainage switch knob 310 uses a single control handle. The valve core body 300 is axially provided with two guiding holes 3000 that are slidably matched with the lifting pull rods 312. The tops of the two lifting pull rods 312 are respectively connected with stop push rods 313 that extend out from the guiding holes 3000 along the radial direction of the valve core body 300. Corresponding to the valve core body 300, a sliding groove 3001 that is communicated with the guiding holes 3000 and is convenient for the stop push rods 313 on the lifting pull rods 312 to slide therein is radially provided. The guiding sliding sleeve 311 is installed inside the water drainage switch knob 310 and is sleeved on the valve core body 300 together. An inclined arc surface groove 3110 that is symmetrically opened is axially formed on the outer circumferential wall of the guiding sliding sleeve 311. The inclined arc surface groove 3110 is in sliding contact with the stop push rods on the two lifting pull rods 312 respectively. The water drainage switch knob 310 drives the guiding sliding sleeve 311 to rotate synchronously. When the guiding sliding sleeve 311 rotates clockwise, the inclined surface a on the right side of the inclined arc surface groove 3110 pushes the lifting pull rod 312 on the right side of the valve core body 300 to rise. When the guiding sliding sleeve 311 rotates counterclockwise, the inclined surface b on the left side of the inclined arc surface groove 3110 pushes the lifting pull rod 312 on the left side of the valve core body 300 to rise.

[0060] Moreover, as shown in FIGS. 4 and Figure 7 , the lower ends of the two lifting pull rods 312 are respectively connected with the wire-controlled pulling steel wires 9 corresponding to each water drainer 7 in the two cavities 20 of the water tank body 2. When the water drainage switch knob 310 and the guiding sliding sleeve 311 are located at the middle position between the two lifting pull rods 312, the drain ports 4 of the water drainers 7 corresponding to the two cavities 20 of the water tank body 2 are controlled to be closed simultaneously. When the water drainage switch knob 310 and the guiding sliding sleeve 311 rotate clockwise, the inclined surface on the right side of the guiding sliding sleeve 311 pulls the lifting pull rod 312 on the right side of the valve core body 300 to rise, and drives the touch control member 10 through the wire-controlled pulling steel wire 9 on the right side, and jacks up the sealing cover 8 of the water drainer 7 in the right cavity 20 of the water tank body 2 to control the drain port 4 on the right cavity 20 of the water tank body 2 to open. When the water drainage switch knob 310 and the guiding sliding sleeve 311 rotate counterclockwise, the inclined surface on the left side of the guiding sliding sleeve 311 pulls the lifting pull rod 312 on the left side of the valve core body 300 to rise, and drives the touch control member 10 through the wire-controlled pulling steel wire 9 on the left side, and jacks up the sealing cover 8 of the water drainer 7 in the left cavity 20 of the water tank body 2 to control the drain port 4 on the left cavity 20 of the water tank body 2 to open.

[0061] In addition, as shown in Figure 4 , Figure 7 , Figure 11 and Figure 12As shown, the drainer 7 is in the shape of a round barrel. A circular sealing cover 8 is inserted above the drain opening 4 of the round-barrel-shaped drainer 7. A central positioning shaft 80 extends downward from the center of the bottom end of the sealing cover 8. A central guiding hole 70 that cooperates with the central positioning shaft 80 is provided at the center of the corresponding drain opening 4 of the drainer 7, which facilitates the insertion of the sealing cover 8 to seal the entire drain opening 4 and the raising of the sealing cover 8 to open the drain opening 4. A guide connection cover 71 communicating with the drain pipe is also threadedly connected to the bottom end of the drainer 7. Among them, the touch control member 10 is an L-shaped deflecting member. A receiving cavity 72 for accommodating the L-shaped deflecting member is formed below the central guiding hole 70 of the round-barrel-shaped drainer 7. The corner of the L-shaped deflecting member is hinged to the inner wall of the round-barrel-shaped drainer 7. A hinge support shaft 73 for hinging and fixing the L-shaped deflecting member extends from the corresponding inner wall of the round-barrel-shaped drainer 7 into the receiving cavity 10. A side guiding through hole 74 is provided at the side wall of the corresponding round-barrel-shaped drainer 7 above the L-shaped deflecting member, which facilitates the direct insertion of the wire-controlled pulling steel wire rope 9 and is straightly connected and fixed to the upper side of the L-shaped deflecting member. A leakage blocking cover 11 is also provided at the outer wall of the corresponding round-barrel-shaped drainer 7 of the side guiding through hole 74, which facilitates the sliding of the wire-controlled pulling steel wire rope 9 and seals the side guiding through hole 74 to prevent the drainer 7 from leaking water. A pushing block 100 that contacts the central positioning shaft 80 at the lower center of the bottom end of the sealing cover 8 is provided at the lower end of the L-shaped deflecting member corresponding to the lower side of the central guiding hole 70. The L-shaped deflecting member deflects a certain angle around the hinge support shaft 73 under the pulling of the wire-controlled pulling steel wire rope 9, contacts the end of the central positioning shaft 80, and pushes the sealing cover 8 to rise to open the drain opening 4 of the drainer 7.

[0062] As Figure 4 , Figure 7 , Figure 11 and Figure 12 shown, three diversion ports 40 that are evenly distributed and facilitate the discharge of the water body in the cavity 20 of the sink body 2 are also provided at the drain opening 4 in the circumferential direction of the central guiding hole 70. Among them, the L-shaped deflecting member avoids the diversion ports 40 and is installed in the receiving cavity 72 below the central guiding hole 70. A shielding cover 12 that covers the upper side of the L-shaped deflecting member is provided in the circumferential direction of the corresponding central guiding hole 70 to prevent the water body in the cavity 20 from directly flushing the L-shaped deflecting member or preventing foreign objects in the water body from winding around the L-shaped deflecting member to block the drain opening 4.

The valve core body 300 is axially provided with guide holes 3000 that slidably cooperate with the upper handle lifting pull rod 314' and the lower handle lifting pull rod 315' respectively. At the top of the upper handle lifting pull rod 314', upper handle stop push rods 3140' extending radially from the guide holes along the valve core body 300 are respectively connected. At the top of the lower handle lifting pull rod 315', lower handle stop push rods 3150' extending radially from the guide holes 3000 along the valve core body 300 are respectively connected. Corresponding to the valve core body 300, chutes 3001 communicating with their respective guide holes are radially provided to facilitate the sliding of the upper handle stop push rod 3140' or the lower handle stop push rod 3150' therein.
