Description

Technical Field

[0001] This utility model relates to the field of kitchen equipment technology, specifically to a pulsator cleaning machine and an integrated sink. Background Technology

[0002] The sink-type washer inside the integrated sink is used to wash dishes, fruits and vegetables, etc.

[0003] To improve cleaning results, people have applied the rotating impeller cleaning solution to sink-type dishwashers. For example, the Chinese patent application number CN201820891413.7, "A Sink Dishwasher", places the impeller assembly at the bottom of the dish rack to rotate and repeatedly rise and fall, enhancing the turbulence of the water and making the cleaning more efficient and faster.

[0004] However, for existing impeller washing machines, firstly, the inner tub rotates when the washing water is used. To avoid interference from the rotating inner tub, a complex connection structure is usually required to connect the water inlet pipe to the inner tub, which is costly. Secondly, while they generally have an automatic water inlet function, each function is typically associated with a separate electrical component, ultimately leading to a conflict between cost and functional innovation. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a pulsator cleaning machine that does not require additional complex water inlet connection structure.

[0006] The second technical problem to be solved by this utility model is to provide a pulsator cleaning machine that can achieve multiple functions at low cost.

[0007] The third technical problem to be solved by this utility model is to provide an integrated water tank that uses the above-mentioned impeller cleaning machine.

[0008] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a pulsator cleaning machine, comprising...

[0009] Outer drum;

[0010] The inner tub is located inside the outer tub;

[0011] A first driving component, located outside the outer tub, has its power output shaft extending upwards through the bottom wall of the outer tub and connected to the inner tub for driving the inner tub to rotate; and

[0012] The water inlet pipe is used to supply cleaning water to the inner tub.

[0013] The feature is that the power output shaft of the first driving member is a hollow shaft, the bottom end of which extends downward and outward to the bottom of the first driving member, and is rotatably connected to the port of the water outlet end of the water inlet pipe.

[0014] To enable automatic water intake, a first valve is also included for controlling the opening and closing of the water inlet pipe.

[0015] To facilitate control of the water inlet pipe's on / off state, the first valve includes:

[0016] A piston having a plug for sealing the inlet pipe; and

[0017] The second driving component, whose power output end drives the piston to rise and fall through the first transmission assembly, so that the plug seals or releases the blockage of the water inlet pipe.

[0018] To facilitate piston installation, the inlet pipe has a stepped hole that is larger at the top and smaller at the bottom. The piston can be axially slidably installed in the larger hole of the stepped hole, and the plug protrudes from the bottom of the piston.

[0019] With the first valve closed, the plug is inserted into the small hole of the stepped hole to block the water inlet pipe, thereby disconnecting the water inlet pipe.

[0020] With the first valve open, the plug disengages from the small hole of the stepped hole, thus releasing the blockage on the inlet pipe and allowing the inlet pipe to connect.

[0021] To further address the second technical problem mentioned above, the first driving component and the second driving component are the same driving component.

[0022] In order to convert the rotational motion of the power output shaft into the lifting motion of the piston, the first transmission assembly is housed within the large hole of the stepped bore, and includes...

[0023] An internally threaded tube is connected to the top of the piston; and

[0024] An externally threaded pipe is connected to the bottom end of the power output shaft of the second drive component and is threadedly connected to the internally threaded pipe.

[0025] To prevent the piston from clogging the stepped hole, the piston has multiple through-holes on its periphery.

[0026] To ensure full water intake, a pulsator is also included at the bottom of the inner cavity of the inner barrel. The pulsator has a water inlet chamber inside and a water outlet hole connected to the water inlet chamber on its surface. The top end of the power output shaft of the first drive unit extends upward into the water inlet chamber.

[0027] To achieve uniform water intake, the water inlet chamber includes multiple circumferentially spaced and intersecting flow channels, and the number of water outlet holes is multiple, which are spaced along the length of the flow channels.

[0028] To facilitate the formation of the flow channel, the impeller includes:

[0029] The disc body has an upwardly recessed bottom forming multiple circumferentially spaced and intersecting grooves, with water outlet holes perforated through the top wall of each groove; and

[0030] The base includes multiple connecting arms that are spaced apart and intersect each other in a circumferential direction. Each connecting arm corresponds to the recessed strip, covers the bottom of the corresponding recessed strip, and surrounds the recessed strip to form the flow channel.

[0031] The technical solution adopted by this utility model to solve the third technical problem mentioned above is: an integrated water tank using the above-mentioned impeller cleaning machine.

[0032] Compared with the prior art, the advantages of this utility model are:

[0033] First, the hollow pneumatic output shaft delivers the cleaning water supplied by the water inlet pipe to the inner tank. On the one hand, there is no need to set up a complicated water inlet connection structure, which is simple and low in cost. On the other hand, the power output shaft serves both as a drive and a water guide, making it a dual-purpose device.

[0034] Secondly, by setting the first and second driving components as the same driving component, the two major functions of inner tub rotation and automatic water filling can be realized with only one electrical component, achieving multi-functionality at low cost. Attached Figure Description

[0046] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0047] 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.

[0048] like Figures 1 to 11 The image shows a preferred embodiment of the integrated water tank of this utility model, which incorporates a pulsator cleaning machine. The pulsator cleaning machine includes a support base 10, an outer tub 1, an inner tub 2, a pulsator disc 3, a drive assembly 4, a water inlet pipe 5, a first valve 6, a drain pipe 7, and a second valve 8.

[0049] The outer barrel 1 has a drain outlet 11 on its bottom wall, and the drain outlet 11 is covered with a filter screen 12.

[0050] The inner tub 2 is located inside the outer tub 1. Specifically, the bottom of the inner tub 2 has a mounting groove 21, and the inner wall of the mounting groove 21 has multiple driven ribs 211 arranged at intervals along the circumference. The bottom of each driven rib 211 has a limiting block 2111. The bottom wall inside the inner tub 2 has a recessed part 22.

[0051] The impeller 3 is installed in the recess 22 and includes a disc body 31 and a base 32.

[0052] Specifically, the bottom of the disc body 31 is recessed upward to form multiple recessed strips 311 that are spaced apart and intersect in the circumferential direction, and multiple water outlet holes 3111 are provided through the top wall of each recessed strip 311 that are spaced apart along the length direction of the recessed strip 311.

[0053] The base 32 includes multiple connecting arms 321 arranged at intervals along the circumference and intersecting each other. Each connecting arm 321 corresponds to the aforementioned recessed strip 311, covers the bottom of the corresponding recessed strip 311, and surrounds the recessed strip 311 to form a flow channel 301. The inward-facing ends of each flow channel 301 intersect and together form a water inlet cavity 30. The water outlet 3111 is connected to the flow channel 301.

[0054] The drive assembly 4 is used to drive the inner tub 2 to rotate, and includes a rotating seat 41 and a first drive member 42.

[0055] Specifically, the rotating seat 41 can be inserted into the mounting groove 21; the outer peripheral wall of the rotating seat 41 is provided with a plurality of transmission blocks 411 arranged circumferentially, and a channel 4110 is formed between two adjacent transmission blocks 411. The aforementioned driven ribs 211 correspond one-to-one with the channel 4110 and can pass through the corresponding channel 4110. The limiting block 2111 of each driven rib 211 can be limited to the bottom of the adjacent transmission block 411 during the rotation of the rotating seat 41, so as to prevent the inner barrel 2 from rotating and rising under the action of centrifugal force and detaching from the rotating seat 41.

[0056] The first driving component 42 is a motor, located outside the outer tub 1 and installed at the bottom of the outer tub 1. The top end of its power output shaft 421 passes upward through the bottom wall of the outer tub 1 and is connected to the rotating seat 41 to drive the rotating seat 41 to rotate. In addition, the power output shaft 421 is sealed with the outer tub 1 through an oil seal.

[0057] When the first drive unit 42 is activated, the rotating seat 41 is driven to rotate through the power output shaft 421. When the transmission block 411 rotates to contact the adjacent driven rib 211, it will drive the entire inner tub 2 to rotate synchronously through the driven rib 211. At this time, the limiting block 2111 of the driven rib 211 is limited to the bottom of the adjacent transmission block 411, realizing the inverted hanging effect and preventing the inner tub 2 from rotating and rising under the action of centrifugal force (whether it is left-handed or right-handed) and detaching from the rotating seat 41.

[0058] In order to facilitate the passage of the limiting block 2111 through the channel 4110 while preventing the inner barrel 2 from easily detaching from the rotating seat 41, the width of the limiting block 2111 is denoted as W1, and the width of the channel 4110 is denoted as W2, where W1 < W2 < 1.5W1.

[0059] In order to guide the limiting block 2111 downward into the channel 4110, thereby facilitating the installation of the inner barrel 2, the bottom of both sides of the limiting block 2111 has a first guide slope 2112 corresponding to the adjacent transmission block 411. The first guide slope 2112 gradually approaches the corresponding transmission block 411 from bottom to top. The top of both sides of the transmission block 411 has a second guide slope 4111 corresponding to the adjacent driven rib 211. The second guide slope 4111 gradually approaches the corresponding driven rib 211 from top to bottom.

[0060] In order to guide the limiting block 2111 upward into the channel 4110, thereby facilitating the disassembly of the inner barrel 2, the top of both sides of the limiting block 2111 has a third guide slope 2113 corresponding to the adjacent transmission block 411. The third guide slope 2113 gradually approaches the corresponding transmission block 411 from top to bottom.

[0061] The water inlet pipe 5 is a rigid pipe, vertically installed on the support base 10, and is used to supply cleaning water. Specifically, the water inlet pipe 5 has a stepped hole 51 that is larger at the top and smaller at the bottom.

[0062] The first valve 6 is used to control the opening and closing of the water inlet pipe 5, and includes a piston 61, an internal threaded pipe 62, an external threaded pipe 63, and a second drive component 64.

[0063] Specifically, the piston 61 is axially slidably installed in the large hole of the stepped hole 51; the bottom of the piston 61 is provided with a plug 611 for sealing the small hole of the stepped hole 51, and two sealing rings arranged one above the other are installed on the outer periphery of the plug 611; the periphery of the piston 61 has multiple through-holes 612.

[0064] The internally threaded tube 62 is housed in the large hole of the stepped hole 51 and connected to the top of the piston 61;

[0065] The externally threaded tube 63 is housed in the large hole of the stepped hole 51 and is threadedly connected to the internally threaded tube 62.

[0066] The second drive member 64 is the same drive member as the first drive member 42. Its power output end 641 is a hollow shaft. The top end of the power output shaft 641 extends upward into the water inlet cavity 30 and is sealed with the impeller 3 through a sealing ring. The bottom end of the power output shaft 641 extends downward outward to the bottom of the second drive member 64 and is rotatably connected to the top end of the stepped hole 51 (i.e., the water outlet end of the water inlet pipe 5) and is sealed with the top end of the water inlet pipe 5 through an oil seal. The top end of the external threaded pipe 63 is connected to the bottom end of the power output shaft 641.

[0067] The second drive unit 64 is activated, which drives the external threaded pipe 63 to rotate via the power output shaft 641. Since the internal threaded pipe 62 is threadedly connected to the external threaded pipe 63, the internal threaded pipe 62 drives the piston 61 to rise and fall synchronously. When the first valve 6 is closed, the plug 611 is inserted into the small hole of the stepped hole 51 to block the water inlet pipe 5, thereby disconnecting the water inlet pipe 5. When the first valve 6 is open, the plug 611 is disengaged from the small hole of the stepped hole 51 to release the blockage on the water inlet pipe 5, thereby allowing the water inlet pipe 5 to be connected.

[0068] The drain pipe 7 is connected to the drain outlet 11, and at least a portion of it is a flexible section 71 for draining the cleaning water. In this embodiment, the entire drain pipe 7 is a flexible pipe.

[0069] The second valve 8 is used to control the opening and closing of the drain pipe 7, and includes a pipe clamp seat 81, a movable pipe clamp 82, an elastic element 83, a push rod 84, a sliding seat 85, a gear 86, and a third drive element 87.

[0070] Specifically, the pipe clamp seat 81 is arranged around the outer periphery of the flexible section 71. The pipe clamp seat 81 has a fixed pipe clamp 811 and a limiting seat 812 located on the left and right sides of the flexible section 71, respectively. The fixed pipe clamp 811 is arranged close to the flexible section 71.

[0071] The movable pipe clamp 82 is slidably installed between the fixed pipe clamp 811 and the limiting seat 812 of the pipe clamp seat 81, and is located on the right side of the flexible section 71; in addition, the limiting seat 812 and the movable pipe clamp 82 are respectively provided with a first limiting post 8121 and a second limiting post 821 on their opposite surfaces.

[0072] The elastic element 83 is a compression spring. The two ends of the compression spring are respectively sleeved on the outer periphery of the first limiting post 8121 and the second limiting post 821, and respectively abut against the opposite surfaces of the limiting seat 812 and the movable tube clamp 82, so that the movable tube clamp 82 always has a tendency to move toward the fixed tube clamp 811.

[0073] There are two push rods 84, which are located on the front and rear sides of the fixed pipe clamp 811 respectively. Each push rod 84 extends in the left and right direction and is used to push the movable pipe clamp 82 to move away from the fixed pipe clamp 811.

[0074] The sliding seat 85 is slidably mounted on the support seat 10 and has a rack 851 extending along the length of the push rod 84, which is connected to the right end of the sliding seat 85.

[0075] Gear 86 meshes with rack 851;

[0076] The third drive member 87 is the same drive member as the first drive member 42. The bottom end of its power output shaft 871 extends downward and outward from the bottom of the third drive member 87. The gear 86 is coaxially connected to the outer periphery of the power output shaft 871.

[0077] When the third drive unit 87 is activated, the gear 86 is driven to rotate via the power output shaft 871. Since the rack 851 and the gear 86 mesh, the sliding seat 85 drives the push rod 84 to move horizontally. When the second valve 8 is closed, the push rod 84 disengages from the movable pipe clamp 82, so that it cooperates with the fixed pipe clamp 811 to clamp the flexible section 71 under the elastic force of the elastic element 83, thereby disconnecting the drain pipe 7. When the second valve 8 is open, the push rod 84 abuts against the left side of the movable pipe clamp 82, so that it overcomes the elastic force of the elastic element 83 and releases the clamp on the flexible section 71, thereby connecting the drain pipe 7.

[0078] As can be seen, the aforementioned drive assembly 4, the first valve 6, and the second valve 8 share the same drive source, so that the impeller cleaning machine has at least three states that do not interfere with each other:

[0079] In the first state, such as Figure 3 and Figure 4 As shown, both the first valve 6 and the second valve 8 are closed;

[0080] In the second state, such as Figure 5 and Figure 6 As shown, the first valve 6 is open, and the second valve 8 is closed;

[0081] In the third state, such as Figure 7 and Figure 8 As shown, the first valve 6 is closed and the second valve 8 is open.

[0082] The working principle of this embodiment is as follows:

[0083] (1) During installation, simply align the mounting slot 21 of the inner tub 2 with the rotating seat 41 and place it into the outer tub 1. Under the action of gravity, the limiting blocks 2111 of each moving rib 211 will slide down the guide slope into the corresponding channel 4110 and pass through the channel 4110, thereby installing the inner tub 2 in place.

[0084] (2) During work:

[0085] Cleaning mode: When cleaning is required, the drive unit intermittently rotates forward and backward x times, causing the entire inner tub 2 to rotate synchronously, such as... Figure 3 As shown, the plug 611 in the first valve 6 is always inserted into the small hole of the stepped hole 51 during the lifting and lowering process, thus blocking the water inlet pipe 5 and disconnecting the water inlet pipe 5. At the same time, as Figure 4 As shown, the push rod 84 in the second valve 8 is always disengaged from the movable pipe clamp 82 during the translation process, so that it cooperates with the fixed pipe clamp 811 to clamp the flexible section 71 under the elastic force of the elastic element 83, thereby disconnecting the drain pipe 7. That is, the first valve 6 and the second valve 8 are always closed and will not affect the cleaning.

[0086] Water intake mode: When water needs to be introduced, the drive unit reverses the rotation by y revolutions, such as... Figure 5 As shown, the plug 611 of the first valve 6 disengages from the small hole of the stepped hole 51, thus releasing the blockage on the inlet pipe 5 and allowing the inlet pipe 5 to be connected. Simultaneously, as... Figure 6 As shown, the push rod 84 in the second valve 8 is still disengaged from the movable pipe clamp 82, so that it can cooperate with the fixed pipe clamp 811 to clamp the flexible section 71 under the elastic force of the elastic element 83, thereby disconnecting the drain pipe 7, that is, the first valve 6 is opened and the second valve 8 is closed. The cleaning water is sequentially transported to the inlet chamber 30 through the inlet pipe 5 and the power output shaft, and diffused to each flow channel 301, and finally enters the inner cavity of the inner barrel 2 through the outlet hole 3111.

[0087] Drainage mode: When drainage is needed, the drive unit rotates clockwise by Z revolutions, such as... Figure 7 As shown, the plug 611 in the first valve 6 is still inserted in the small hole of the stepped hole 51 to block the water inlet pipe 5, so that the water inlet pipe 5 is disconnected. At the same time, as Figure 8 As shown, push rod 84 abuts against the left side of movable pipe clamp 82 so that it overcomes the elastic force of elastic element 83 and releases the clamp on flexible section 71, thereby connecting drain pipe 7, that is, first valve 6 is closed and second valve 8 is opened, the cleaning water in inner tub 2 enters outer tub 1 through the gap between inner tub 2 and power output shaft, and is finally discharged through drain outlet 11 and drain pipe 7.

[0088] Where y > x and z > x, x is preferably 3, y is preferably 10, and z is preferably 5;

[0089] (3) When disassembling, simply lift the inner tub 2 upwards. Under the action of the pulling force, the limiting blocks 2111 of each moving rib 211 can slide upwards along the guide slope into the corresponding channel 4110 and pass through the channel 4110, thereby removing the inner tub 2 and the impeller 3, which is convenient for cleaning the inner tub 2 and the impeller 3.
