Technical Field

[0001] This utility model relates to the field of kitchen equipment technology, specifically to a filter installation structure and a cleaning sink. Background Technology

[0002] Traditional washing sinks typically only have a basin, and when washing food, plates or dishes are needed to hold the cleaned food, making them inconvenient to use.

[0003] To address this issue, Chinese patent application CN200420072388.8, entitled "A Kitchen Sink," provides a kitchen sink comprising a sink body with at least one trough. Horizontal continuous slide rails are provided on the front and rear walls of the trough. A tray is mounted on the slide rails, with rollers located at the four lower corners of the tray. When washing food, there is no need to use separate plates or dishes; food can be placed directly on the tray, which is easy to move and remove, making it very convenient to use.

[0004] Nowadays, most electric sinks use one of the sinks as a fixed sink for washing and purifying food, and even circulate water for washing. In order to achieve the filtration function in the water circulation, a filter is usually installed on the water outlet channel. However, the existing filter is usually installed on the water inlet base with fasteners, which is troublesome to install and remove, and inconvenient to clean or replace. Utility Model Content

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0040] like Figures 1 to 14 The image shows a preferred embodiment of the cleaning water tank with a filter installation structure according to this utility model. The cleaning water tank includes a tank body 1, a tray 2, a water inlet seat 3, a drain valve 4, a Hall sensor 5, a water inlet device 6, and a drive device 7.

[0041] The tank 1 has support bars 11 extending in the left and right directions on the side walls on both the front and rear sides.

[0042] The tray 2 is slidably installed in the tank 1. Specifically, the tray 2 contains a drain basket 20; the top edge of the tray 2 extends outward to form a folded edge, and the folded edges on the front and rear sides of the tray 2 are called sliding strips 21. These sliding strips 21 correspond to the support strips 11 and can slide left and right on the corresponding support strips 11; the rear side wall of the tray 2 has spaced water inlet holes 22, water outlet holes 23, and water passage holes 25; the rear side of the bottom of the tray 2 has a sloping wall that gradually extends backward from bottom to top, and a drain hole 24 is provided on this sloping wall; the bottom surface inside the tray 2 gradually rises from the periphery of the drain hole 24 to the outer periphery of the tray 2; a hinge seat 26 with a pin 261 is provided inside the tray 2 near the drain hole 24. In this embodiment, the tank 1 has a cleaning position, and when the tray 2 moves to its right limit position, the tray 2 is in the cleaning position.

[0043] The water inlet base 3 is installed on the rear side of the tray 2. The interior of the water inlet base 3 has an independent water inlet channel 31, a water outlet channel 32, and a float cavity 35. The outlet of the water inlet channel 31 is connected to the water inlet hole 22, and the inlet of the water outlet channel 32 is connected to the water outlet hole 23. A slot 33 is provided on the right side of the water inlet base 3, which is arranged to cross the water outlet channel 32. A filter element 34 is pluggably installed in the slot 33. The filter element 34 is arranged on the flow path of the water in the water outlet channel 32 and is used to filter the water flowing through the water outlet channel 32. A magnetic float 36 is placed in the float cavity 35. The magnetic float 36 includes a housing 361 and a magnet 362 housed in the housing 361. The magnetic float 36 is limited to the float cavity 35 and can move up and down. Since the float cavity 35 is connected to the water inlet hole 25, the magnetic float 36 can float up and down with the water level in the tray 2.

[0044] In this embodiment, the filter element 34 includes a support frame 341, a plug 342, a filter screen 343, and a sealing sleeve 344. Specifically, the top and bottom sides of the slot 33 are provided with slide rails 331 extending along the insertion and removal direction of the filter element 34. The side edges of the top and bottom sides of the support frame 341 can be slidably inserted into the corresponding slide rails 331. The plug 342 is connected to the right end of the support frame 341 and seals the opening of the slot 33. The end wall of the right end of the plug 342 is provided with a gripping part 3422 for the user to hold. The filter screen 343 is fixed on the support frame 341. The sealing sleeve 344 is fitted on the outer periphery of the plug 342. The outer periphery wall of the sealing sleeve 344 is provided with two first annular lips 3441 arranged at intervals along the insertion and removal direction of the filter element 34. Each first annular lip 3441 gradually moves away from the filter screen 343 from the head to the tail, and the tail of the first annular lip 3441 is tightly attached to the inner periphery wall of the slot 33 for sealing. The first annular lip 3441 can simultaneously play the role of sealing and installation damping positioning. In addition, the inner peripheral wall of the slot 33 and the outer peripheral wall of the plug 342 are respectively provided with an inner step 332 and an outer step 3421 that cooperate with each other. When the filter element 34 is inserted into the slot 33, the outer step 3421 is limited to the outside of the inner step 332, thereby achieving stable positioning of the filter element 34.

[0045] The drain valve 4 is installed at the drain hole 24 and includes a cover plate 41, an elastic element 42, a push rod 43 and a sealing ring 44.

[0046] Specifically, the top of the cover plate 41 is rotatably connected to the pin 261, and a pressure block 411 is protruding on the rear surface of the cover plate 41. The top of the pressure block 411 has a pressure surface 4111 for the push rod 43 to abut against. The elastic element 42 is a torsion spring, which is sleeved on the outer periphery of the pin 261, and the two ends of the torsion spring abut against the hinge seat 26 and the cover plate 41 respectively, so that the cover plate 41 always tends to cover the drain hole 24. The push rod 43 is movably mounted on the rear side wall of the tank 1 to push the cover plate 41 to flip upward and release the cover of the drain hole 24. The sealing ring 44 is embedded on the rear surface of the cover plate 41, and a second annular lip 441 is protruding on the rear end face of the sealing ring 44. When the cover plate 41 covers the drain hole 24, the tail of the second annular lip 441 is tightly attached to the edge of the drain hole 24 for sealing.

[0047] In addition, the initial and final positions of the pressure surface 4111 in contact with the push rod 43 when the cover plate 41 is pushed are respectively recorded as the first contact point and the second contact point. When the cover plate 41 covers the drain hole 24, the pressure surface 4111 gradually approaches the push rod 43 from the first contact point to the second contact point. In this embodiment, the pressure surface 4111 gradually extends backward from top to bottom. In this way, during the process of the cover plate 41 flipping upward, although the pressure surface 4111 will move forward as the cover plate 41 flips, the inclination of the pressure surface 4111 compensates for part of the forward movement of the pressure surface 4111 because the contact position between the push rod 43 and the pressure surface 4111 changes at the same time. Therefore, the push rod 43 only needs to move forward a short distance to open the cover plate 41 at a large angle.

[0048] Hall sensor 5 is installed on the rear side of tank 1. When tray 2 is in the cleaning position and magnetic float 36 is below the warning level, magnetic float 36 is within the sensing range of Hall sensor 5. Through the cooperation of Hall sensor 5 and magnetic float 36, it is possible to monitor whether tray 2 is in position and whether the water level in tray 2 has reached the warning level.

[0049] The water inlet device 6 is installed on the rear side of the tank 1 and includes an inlet pipe 61, an outlet pipe 62, a tee pipe 63, a first valve 64, a water pump 65, and a second valve 66. Specifically, the inlet pipe 61 is used to supply water to the tray 2 and includes a first inlet section 611 and a second inlet section 612 arranged sequentially along the water inlet direction. The inlet of the first inlet section 611 is connected to an external tap water pipe, and the outlet of the second inlet section 612 is connected to an inlet connector 6121, which is movably installed on the rear side wall of the tank 1. The outlet pipe 62 is used to discharge water from the tray 2, and the inlet of the outlet pipe 62 is connected to an outlet connector 621, which is movably installed on the rear side wall of the tank 1. The tee pipe 63 has a first port. The tee pipe 63 has a first port connected to the outlet of the first inlet section 611, a second port connected to the inlet of the second inlet section 612, and a third port connected to the outlet of the outlet pipe 62. The first valve 64 is a solenoid valve installed on the first inlet section 611 to control the opening and closing of the first inlet section 611. The water pump 65 is installed on the second inlet section 612 to transport water from the inlet of the second inlet section 612 to the outlet. The second valve 66 is a solenoid valve installed on the outlet pipe 62 to control the opening and closing of the outlet pipe 62.

[0050] The aforementioned water inlet device 6 has three states: water filling, water circulation, and backwashing.

[0051] When water is being added, the first valve 64 is open, the water pump 65 is open, and the second valve 66 is closed;

[0052] In water circulation mode, the first valve 64 is closed, the water pump 65 is open, and the second valve 66 is open;

[0053] In the backwashing state, the first valve 64 is open, the water pump 65 is closed, and the second valve 66 is open.

[0054] The drive device 7 is located at the rear of the tank 1 and is used to drive the aforementioned water inlet connector 6121, water outlet connector 621, and push rod 43 to move back and forth. That is, the water inlet connector 6121, water outlet connector 621, and push rod 43 share the same drive device 7. Alternatively, three drive devices can be used to drive the water inlet connector 6121, water outlet connector 621, and push rod 43 to translate respectively to achieve the same purpose. In this embodiment, the drive device 7 includes a fixed box 71, a first guide seat 72, a first slider 73, a second guide seat 74, a second slider 75, a rack 76, a gear 77, and a drive component 78.

[0055] Specifically, the fixing box 71 is installed on the rear side of the tank 1;

[0056] The first guide seat 72 is movable up and down in the fixed box 71. The left and right sides of the first guide seat 72 have first guide grooves 721. Each first guide groove 721 includes a first inclined groove section 7211 that gradually extends forward from bottom to top and a first vertical groove section 7212 that extends vertically upward from the top of the first inclined groove section 7211.

[0057] The first slider 73 can be installed in the fixed box 71 in a back-and-forth motion. The left and right sides of the first slider 73 have first guide rods 731 that correspond to the first guide grooves 721 and are inserted into the corresponding first guide grooves 721. The tails of the water inlet connector 6121 and the water outlet connector 621 are connected to the first slider 73.

[0058] The second guide seat 74 can be installed in the fixed box 71 in a vertically movable manner. The second guide seat 74 has a second guide groove 741 on its left and right sides. The second guide groove 741 includes a second inclined groove section 7411 that gradually extends forward from bottom to top and a second vertical groove section 7412 that extends vertically downward from the bottom end of the second inclined groove section 7411.

[0059] The second slider 75 can be installed in the fixed box 71 in a back-and-forth motion. The left and right sides of the second slider 75 have second guide rods 751 that correspond to the second guide groove 741 and can be slidably inserted into the second guide groove 741. The tail of the push rod 43 is connected to the second slider 75.

[0060] The rack 76 is installed in the fixed box 71 and fixed relative to the first guide seat 72 and the second guide seat 74. In this embodiment, the rack 76 and the first guide seat 72 are an integral part, and the second guide seat 74 is fixed on the first guide seat 72.

[0061] The gear 77 is rotatably mounted in the fixed box 71 and meshes with the rack 76;

[0062] The drive component 78 is a motor, which is installed in the fixed box 71, and its power output shaft is coaxially connected to the gear 77.

[0063] The drive unit 78 is activated, causing the gear 77 to rotate. Since the rack 76 meshes with the gear 77, the rack 76 subsequently drives the first guide seat 72 and the second guide seat 74 to rise and fall. Due to the guiding engagement between the first guide rod 731 and the first guide groove 741, and between the second guide rod 751 and the second guide groove 741, the inlet connector 6121, the outlet connector 621, and the push rod 43 are sequentially moved back and forth, so that the cleaning tank has at least three states:

[0064] In non-working state, such as Figure 11 As shown, the head of the inlet connector 6121 is detached from the inlet channel 31, and the head of the outlet connector 621 is detached from the outlet channel 32.

[0065] In the first and second working states, such as Figure 12 As shown, tray 2 is in the cleaning position, the head of water inlet connector 6121 is inserted into the inlet end of water inlet channel 31 and sealed, and the head of water outlet connector 621 is inserted into the outlet end of water outlet channel 32 and sealed.

[0066] Additionally, in the non-working state and the first working state, such as Figure 13 As shown, push rod 43 disengages from cover plate 41, so that cover plate 41 covers drain hole 24 under the elastic force of elastic member 42; in the second working state, as Figure 14 As shown, push rod 43 abuts against the right side of pressure surface 4111 to cause cover plate 41 to flip upward and remove the cover of drain hole 24.

[0067] It should be noted that the first vertical groove section 7212 is designed to allow the water inlet connector 6121 and the water outlet connector 621 to have a free stroke during the translation of the push rod 43. Similarly, the second vertical groove section 7412 is designed to allow the push rod 43 to have a free stroke during the translation of the water inlet connector 6121 and the water outlet connector 621, thereby avoiding interference between their movements.

[0068] In addition, the above-mentioned cleaning water tank has a controller. The Hall sensor 5, the first valve 64, the water pump 65, the second valve 66 and the drive device 7 are all connected to the controller so that the controller can receive the signal from the Hall sensor 5 and control the drive device 7 to drive the water inlet connector 6121 and the water outlet connector 621 to move back and forth, control the opening and closing of the first valve 64 and the second valve 66 and the start and stop of the water pump 65.

[0069] The working principle of this embodiment is as follows:

[0070] (1) When the food washing function of tray 2 is not needed, such as Figure 11 As shown, the cleaning tank is in a non-working state, the head of the water inlet connector 6121 is disengaged from the water inlet channel 31, and the head of the water outlet connector 621 is disengaged from the water outlet channel 32. At this time, the tray 2 can slide freely in the tank 1 in the left and right directions, and can also be removed from the tank 1 without affecting the use of the tank 1.

[0071] (2) When the food washing function of tray 2 needs to be used, tray 2 can be moved to the right to its extreme position (i.e., the washing position). At this time, Hall sensor 5 triggers the Hall effect, and the controller starts the drive device 7 to drive the inlet connector 6121 and the outlet connector 621 to move forward synchronously, so that the head of the inlet connector 6121 is inserted into the inlet end of the inlet channel 31 and sealed, and at the same time, the head of the outlet connector 621 is inserted into the outlet end of the outlet channel 32 and sealed. At this time, the washing tank is in the first working state, such as Figure 12As shown, the inlet connector 6121 and the outlet connector 621 are connected to the tray 2 to form an inlet and outlet water passage. Simultaneously, the tray 2 is fixed to form a fixed cleaning chamber. Meanwhile, as... Figure 13 As shown, push rod 43 disengages from cover plate 41 so that cover plate 41 covers drain hole 24 under the elastic force of elastic member 42.

[0072] When water needs to be added, the controller opens the first valve 64 and the water pump 65 and closes the second valve 66. At this time, tap water enters the tray 2 through the inlet pipe 61, the inlet connector 6121, the inlet flow channel 31 and the inlet hole 22 in sequence, thereby realizing the water adding function. During the water adding process, the magnetic float 36 rises with the water level in the tray 2 until the magnetic float 36 reaches the warning level, the Hall sensor 5 loses the signal, and the controller closes the first valve 64 and the water pump 65 to stop water adding.

[0073] When a cycle cleaning is required, the controller closes the first valve 64 and opens the water pump 65 and the second valve 66. At this time, the water in the tray 2 is discharged sequentially through the water outlet 23, the water outlet channel 32, the water outlet connector 621 and the water outlet pipe 62, and then returns to the tray 2 sequentially through the second water inlet section 612 of the water inlet pipe 61, the water inlet connector 6121, the water inlet channel 31 and the water inlet 22, thereby realizing the water circulation function and making efficient use of water. During this process, the filter element 34 can filter the water flowing through the water outlet channel 32.

[0074] When the filter needs to be cleaned, the controller opens the first valve 64, shuts off the water pump 65, and opens the second valve 66. At this time, tap water enters the tray 2 sequentially through the first inlet section 611 of the inlet pipe 61, the outlet pipe 62, the outlet connector 621, the outlet channel 32, and the outlet hole 23, thereby achieving backwashing of the filter element 34; or the filter element 34 can be directly pulled out of the slot 33 for cleaning.

[0075] When drainage is needed, the controller activates the drive unit 7 to move the push rod 43 forward, causing the push rod 43 to push the cover plate 41 upward and remove the cover from the drainage hole 24. At this time, as Figure 14 As shown, the cleaning tank is in the second working state, and the sewage in the tray 2 is discharged into the tank 1 through the drain hole 24.
