Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, specifically to a washing 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] However, the aforementioned tray is only used as a storage tray and cannot automatically drain water, nor does it have a cleaning or purification function. In addition, most modern electrified sinks now occupy one of the sinks as a fixed sink for cleaning and purifying food, which affects the usable space of the sink and does not conform to the current trend of large single-sink sinks for a better user experience.

[0005] To facilitate food cleaning and purification without affecting the use of the tank, the applicant's earlier Chinese patent application, CN202520068976.6, entitled "A Cleaning Tank," features an inlet and outlet connector on the rear side wall of the tank for docking with a tray. This design simultaneously limits the tray's position and enables automatic water inlet and outlet, facilitating food cleaning and purification. Furthermore, the tray can be removed from the tank without affecting its use.

[0006] However, the above solutions still lack sufficient stability in the connection and sealing reliability between the pallet and the mating parts. Summary of the Invention

[0007] The first technical problem to be solved by the present invention is to provide a cleaning water tank that can improve docking stability in light of the current state of the prior art.

[0008] The second technical problem to be solved by the present invention is to provide a cleaning water tank that can improve the sealing reliability.

[0009] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a cleaning water tank, including a tank body and a tray detachably installed in the tank body, characterized in that: the tank body has a cleaning position, the rear side wall of the tray has a docking hole, and the rear side of the tray has a limiting part at the position of the outer periphery of the docking hole;

[0010] Furthermore, it also includes a docking component, which includes...

[0011] The main body is installed on the rear side wall of the tank.

[0012] The first pair of connecting pipes extends in the front-to-back direction and is installed on the main body in a movable manner;

[0013] The second pair of connectors can be movably fitted around the outer periphery of the first pair of connectors;

[0014] An elastic element acts between the second pair of connectors and the first pair of connectors to ensure that the second pair of connectors always tends to move forward relative to the first pair of connectors; and

[0015] A driving device is used to drive the first pair of pipes to move back and forth;

[0016] The first pair of connecting pipes has a first position, a second position, and a third position in sequence during the forward movement;

[0017] When the tray is in the cleaning position:

[0018] During the process of the first pair of connecting tubes moving from the first position to the second position, the second pair of connecting tubes moves forward synchronously with the first pair of connecting tubes under the elastic force of the elastic member until it abuts against the limiting part.

[0019] During the process of the first pair of connectors moving from the second position to the third position, the first pair of connectors moves forward relative to the second pair of connectors and is inserted into the mating hole.

[0020] To further address the second technical problem mentioned above, a first sealing ring is installed at the limiting part. When the first pair of connecting pipes is in the third position, the second pair of connecting pipes and the first sealing ring perform end face sealing cooperation, and the first pair of connecting pipes and the first sealing ring perform radial sealing cooperation.

[0021] To further improve the sealing effect of the double seal, a first annular sealing strip is provided on the rear end face of the first sealing ring, and a second annular sealing strip is provided on the inner peripheral wall of the first sealing ring.

[0022] With the first pair of connectors in the third position, the front end face of the second pair of connectors abuts against the end of the first annular sealing strip, and the outer peripheral wall of the first pair of connectors abuts against the end of the second annular sealing strip.

[0023] To prevent water from leaking out through the gap between the first pair of connectors and the second pair of connectors, the inner peripheral wall of the second pair of connectors is sealed to the outer peripheral wall of the first pair of connectors by a second sealing ring.

[0024] To facilitate the installation of the main body on the groove, the main body includes a base and a panel installed on the front side of the base. The rear side wall of the groove has an installation opening, the edge of which is sandwiched between the base and the panel.

[0025] To ensure the aesthetics of the cleaning tank when it is not in operation, with the first pair of connecting pipes in the first position, the front ends of the first and second pairs of connecting pipes are flush with the front end of the panel.

[0026] To prevent water in the tank from draining out through the gap between the main body and the second pair of connecting pipes, the outer peripheral wall of the second pair of connecting pipes is sealed to the base by a third sealing ring.

[0027] To prevent water in the tank from draining out through the gap between the main body and the mounting port, the front end face of the base is sealed to the edge of the mounting port by a fourth sealing ring.

[0028] In order to guide the relative movement between the first pair of connectors and the second pair of connectors, the outer periphery of the rear of the first pair of connectors has a first extension seat, and a guide hole is provided through the first extension seat in the front-rear direction.

[0029] The outer periphery of the rear portion of the second pair of connecting pipes has a second extension seat, which has a rearwardly extending guide rod that can slide back and forth through a corresponding guide hole.

[0030] In order to limit the extreme position of the second pair of connectors relative to the first pair of connectors, the rear end of the guide rod has a limiting block, which abuts against the rear side of the first extension seat when no external force is applied to the second pair of connectors.

[0031] To facilitate the installation of the elastic element, the elastic element is a compression spring, which is sleeved on the outer periphery of the guide rod, and the two ends of the compression spring abut against the opposite surfaces of the first extension seat and the second extension seat, respectively.

[0032] To drive the first pair of connecting pipes to move back and forth, the drive device includes:

[0033] A lead screw nut is mounted on the first extension seat;

[0034] A lead screw, extending in the front-to-back direction, is threadedly connected to the lead screw nut; and

[0035] A lead screw motor is used to drive the lead screw to rotate around its own axis.

[0036] To facilitate water inlet and outlet, there are two connecting holes, which are referred to as the water inlet hole and the outlet hole, respectively.

[0037] The first pair of connectors and the second pair of connectors each have two pieces, and they correspond to the docking holes.

[0038] The two first pairs of pipes are connected by a first extension seat, and the two second pairs of pipes are connected by a second extension seat.

[0039] In order to utilize the existing drainage pipes of the tank for drainage and avoid setting up additional drainage pipes for the tray, the front ports of the first pair of connecting pipes corresponding to the drainage hole are closed. When the first pair of connecting pipes is inserted into the drainage hole, the drainage hole is in a closed state.

[0040] To increase the freedom of use of the tray, the tray can be slidably installed in the groove.

[0041] To facilitate the sliding and loading / unloading of the pallet, the side walls on both the front and rear sides of the trough are provided with support bars extending in the left and right directions. The side walls on both the front and rear sides of the pallet are provided with sliding bars corresponding to the support bars, and each sliding bar can slide left and right and rest on the corresponding support bar.

[0042] To facilitate the processing of the slide bar, the edge of the top of the tray extends outward to form the slide bar.

[0043] To facilitate moving the tray to the cleaning position, the tray is in the cleaning position when it is moved to its extreme position to the left or right.

[0044] Compared with the prior art, the advantages of the present invention are as follows:

[0045] (1) The docking assembly, consisting of the main body, the first pair of connecting tubes, the second pair of connecting tubes, the elastic element and the driving device, docks with the docking hole. During the docking process, the first pair of connecting tubes first drives the second pair of connecting tubes to move forward synchronously so that the second pair of connecting tubes abuts against the limiting part of the tray for pre-positioning. Then the first pair of connecting tubes moves forward relative to the second pair of connecting tubes and inserts into the docking hole to achieve motion docking, which can improve docking stability.

[0046] (2) By installing a first sealing ring at the limiting part, when the two pipes are in the docking position, the second pipe pair and the first sealing ring are sealed at the end face, and the first pipe pair and the first sealing ring are sealed radially. This double sealing method can improve the sealing reliability. Attached Figure Description

[0054] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0055] The specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0056] like Figures 1 to 7 The image shows a preferred embodiment of the cleaning tank of the present invention. The cleaning tank includes a tank body 1, a tray 2, and a docking assembly 3.

[0057] The top of the front and rear side walls of the tank 1 has support bars 11 extending in the left and right direction; the rear side wall of the right side of the tank 1 has an installation port 12.

[0058] The tray 2 is slidable left and right and detachably installed in the tank 1. Specifically, 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 referred to as 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 two docking holes 22 arranged one above the other, referred to as a water inlet hole 22a and a drain hole 22b, respectively. The rear side of the tray 2 has a limiting part 23 located at the outer periphery of the docking holes 22. A first sealing ring 24 is installed at the limiting part 23. A first annular sealing strip 241 protrudes rearward on the rear end face of the first sealing ring 24, and a second annular sealing strip 242 protrudes inward on the inner peripheral wall of the first sealing ring 24. In this embodiment, the tank 1 has a cleaning position. When the tray 2 moves to the right to its limit position, the tray 2 is in the cleaning position.

[0059] The docking assembly 3 includes a main body 31, a first coupling tube 32, a second coupling tube 33, an elastic element 34, and a drive device 35.

[0060] Specifically, the main body 31 is installed at the aforementioned mounting opening 12, including a base 311 and a panel 312 installed on the front side of the base 311, with the edge of the aforementioned mounting opening 12 sandwiched between the base 311 and the panel 312.

[0061] There are two first pairs of connectors 32, which correspond one-to-one with the aforementioned docking holes 22. Each first pair of connectors 32 extends in the front-back direction. The two first pairs of connectors 32 are connected by a first extension seat 321 located on the outer periphery of the rear of the first pair of connectors 32. The first extension seat 321 has two guide holes 3211 arranged one above the other in the front-back direction.

[0062] There are two second pairs of connectors 33, which correspond one-to-one with the aforementioned docking holes 22. Each second pair of connectors 33 extends in the front-back direction and can be movably fitted around the outer periphery of the corresponding first pair of connectors 32. The two second pairs of connectors 33 are connected by a second extension seat 331 provided on the rear outer periphery of the second pair of connectors 33. The second extension seat 331 has a guide rod 3311 that extends backward and corresponds one-to-one with the aforementioned guide holes 3211. Each guide rod 3311 can slide back and forth through the corresponding guide hole 3211, and the rear end of each guide rod 3311 has a limiting block 3312.

[0063] There are two elastic elements 34, which correspond one-to-one with the guide rods 3311. Each elastic element 34 is a compression spring, which is sleeved on the outer periphery of the corresponding guide rod 3311, and the two ends of the compression spring abut against the opposite surfaces of the first extension seat 321 and the second extension seat 331, so that the second pair of connecting tubes 33 always has a tendency to move forward relative to the first pair of connecting tubes 32. When no external force is applied to the second pair of connecting tubes 33, the limiting block 3312 abuts against the rear side of the first extension seat 321, thereby limiting the extreme position of the second pair of connecting tubes 33 moving forward relative to the first pair of connecting tubes 32.

[0064] The drive device 35 includes a lead screw nut 351, a lead screw 352, and a lead screw motor 353. The lead screw nut 351 is mounted on the first extension seat 321. The lead screw 352 extends in the front-back direction, and both ends of the lead screw 352 are rotatably connected to the base 311. The lead screw nut 351 is threadedly connected to the outer circumference of the lead screw 352. The power output end of the lead screw motor 353 is connected to the lead screw 352 to drive the lead screw 352 to rotate around its own axis. When the lead screw motor 353 is started, the lead screw 352 is driven to rotate. Since the lead screw nut 351 is threadedly connected to the lead screw 352, the lead screw nut 351 drives the first connecting pipe 32 to move back and forth.

[0065] The first pair of connecting pipes 32 described above have a first position, a second position, and a third position in sequence during the forward movement. When the tray 2 is in the cleaning position:

[0066] During the process of the first pair of connecting tubes 32 moving from the first position to the second position, the second pair of connecting tubes 33 moves forward synchronously with the first pair of connecting tubes 32 under the elastic force of the elastic member 34 until it abuts against the first sealing ring 24 on the limiting part 23.

[0067] During the process of the first pair of connectors 32 moving from the second position to the third position, the first pair of connectors 32 moves forward relative to the second pair of connectors 33 and is inserted into the corresponding mating hole 22;

[0068] With the first pair of connectors 32 in the first position, such as Figure 5 As shown, the front ends of the first pair of connecting pipes 32 and the second pair of connecting pipes 33 are flush with the front end of the panel 312, which can ensure the aesthetics of the cleaning tank when it is not in operation.

[0069] When the first pair of connectors 32 are in the third position, such as Figure 7As shown, the front end face of the second pair of connecting pipes 33 abuts against the end of the first annular sealing strip 241, thereby achieving a face sealing fit between the second pair of connecting pipes 33 and the first sealing ring 24. The outer peripheral wall of the first pair of connecting pipes 32 abuts against the end of the second annular sealing strip 242, thereby achieving a radial sealing fit between the first pair of connecting pipes 32 and the first sealing ring 24. This double sealing method can ensure the sealing reliability between the docking assembly 3 and the docking hole 22, and prevent water from being discharged through the gap between the two.

[0070] In addition, to prevent water from draining through the gap between the first pair of connecting pipes 32 and the second pair of connecting pipes 33, the inner peripheral wall of the second pair of connecting pipes 33 is sealed to the outer peripheral wall of the first pair of connecting pipes 32 by a second sealing ring 332; to prevent water in the tank 1 from draining through the gap between the main body 31 and the second pair of connecting pipes 33, the outer peripheral wall of the second pair of connecting pipes 33 is sealed to the base 311 by a third sealing ring 333; to prevent water in the tank 1 from draining through the gap between the main body 31 and the mounting port 12, the front end face of the base 311 is sealed to the edge of the mounting port 12 by a fourth sealing ring 3111.

[0071] In addition, in this embodiment, the tray 2 adopts an in-slot drainage method. The front port of the first pair of connecting pipes 32 corresponding to the drain hole 22b is closed. When the first pair of connecting pipes 32 is not inserted into the drain hole 22b, the drain hole 22b is in the open state, and the water in the tray 2 can be discharged into the tank 1 through the drain hole 22b. When the first pair of connecting pipes 32 is inserted into the drain hole 22b, the drain hole 22b is in the closed state, and water can be stored in the tray 2.

[0072] The working principle of this embodiment is as follows:

[0073] (1) When the food washing function of tray 2 is not needed, such as Figure 1 and Figure 5 As shown, the first pair of connecting pipes 32 is in the first position, and the front end faces of the first pair of connecting pipes 32 and the second pair of connecting pipes 33 are flush with the front end face of the panel 312. At this time, the tray 2 can slide freely in the tank 1 in the left and right directions, and can also be taken out from the tank 1 without affecting the use of the water tank 1.

[0074] (2) When the food washing function of tray 2 needs to be used, tray 2 can be moved to the right to the extreme position (i.e., the washing position) first, and then the drive device 35 can be started to drive the first pair of pipes 32 to move forward from the first position.

[0075] During the forward movement of the first pair of connecting pipes 32, the second pair of connecting pipes 33, under the elastic force of the elastic member 34, moves forward synchronously with the first pair of connecting pipes 32 until it abuts against the first sealing ring 24 on the limiting part 23 to achieve pre-positioning and stabilize the tray 2. At this time, if Figure 6 As shown, the first pair of connecting pipes 32 moves to the second position;

[0076] The first pair of connecting pipes 32 continues to move forward. During this process, the second pair of connecting pipes 33 is pressed tighter and tighter under the obstruction of the first sealing ring 24 to achieve end face sealing. The first pair of connecting pipes 32 moves forward relative to the second pair of connecting pipes 33 and is inserted into the corresponding mating hole 22 to achieve radial sealing. At this time, if Figure 7 As shown, the first pair of connecting pipes 32 moves to the third position, and a water inlet channel is formed between the first pair of connecting pipes 32 corresponding to the water inlet hole 22a and the water inlet hole 22a. The first pair of connecting pipes 32 corresponding to the drain hole 22b blocks the drain hole 22b. At the same time, the tray 2 is fixed to form a fixed cleaning chamber, which facilitates the cleaning and purification of food.
