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] After cleaning, the cleaning water in the outer bucket is drained through the drain outlet. However, small pores and residual water in corners may remain during the drainage process, which can cause an odor inside the bucket over time. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a pulsator cleaning machine that can reduce residual water, in light of the current state of the prior art.

[0006] The second technical problem to be solved by this utility model is to provide an integrated water tank that uses the above-mentioned impeller cleaning machine.

[0007] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a pulsator cleaning machine, including an outer tub, an inner basket disposed inside the outer tub, and a drive assembly for driving the inner basket to rotate, wherein the bottom of the outer tub has a drain outlet, characterized in that: the bottom surface inside the outer tub gradually rises from the periphery of the drain outlet to the outer periphery of the outer tub.

[0008] To facilitate the drainage of residual water inside the inner basket, the bottom of the inner basket is provided with multiple strip-shaped drainage holes arranged circumferentially, and each of the strip-shaped drainage holes extends radially along the inner basket.

[0009] To facilitate the loading and unloading of the inner basket, the drive assembly includes:

[0010] A rotating seat is rotatably mounted at the bottom of the inner cavity of the outer barrel. Multiple transmission blocks are arranged circumferentially on its outer peripheral wall, with channels forming between adjacent transmission blocks.

[0011] A driving component is used to drive the rotating seat to rotate;

[0012] The bottom of the inner basket has a mounting groove for the rotating seat to be inserted. The inner wall of the mounting groove is provided with multiple driven ribs that correspond to the channels and can pass through the corresponding channels. The bottom end of each driven rib has a limiting block, which is limited to the bottom of the adjacent transmission block during the rotation of the rotating seat.

[0013] In order to facilitate the passage of the limiting block through the channel while preventing the inner basket from easily detaching from the rotating seat, the width of the limiting block is denoted as W1, and the width of the channel is denoted as W2, where W1 < W2 < 1.5W1.

[0014] In order to guide the limiting block into the channel, the bottom of both sides of the limiting block has a first guiding slope corresponding to the adjacent transmission block, and the first guiding slope gradually approaches the corresponding transmission block from bottom to top;

[0015] The top of both sides of the transmission block has a second guide slope corresponding to the adjacent driven rib, and the second guide slope gradually approaches the corresponding driven rib from top to bottom;

[0016] The top of both sides of the limiting block has a third guide slope corresponding to the adjacent transmission block, and the third guide slope gradually approaches the corresponding transmission block from top to bottom.

[0017] To improve the rotational stability of the inner basket, an annular rib is provided on the top wall inside the mounting groove, and multiple arc-shaped ribs are provided on the top wall of the rotating seat at intervals along the circumference, with each arc-shaped rib located on the outer periphery of the annular rib.

[0018] To facilitate the rotation of the rotating seat, the driving component is a motor, which is installed at the bottom of the outer barrel. The power output shaft of the motor passes through the bottom wall of the outer barrel and is connected to the rotating seat.

[0019] To prevent water leakage, the bottom wall of the outer barrel has an upward-facing mounting box. The power output shaft passes through the bottom wall of the mounting box, and an oil seal is fitted around the outer periphery of the power output shaft. The oil seal is housed inside the mounting box and seals against the inner periphery and bottom wall of the mounting box.

[0020] To improve the sealing effect, the top of the rotating seat has a groove, and the bottom of the rotating seat has a pressure ring. The top end of the power output shaft passes through the rotating seat and extends into the groove. The groove contains a nut that is threadedly connected to the power output shaft. The nut abuts against the bottom surface inside the groove, so that the pressure ring extends into the mounting box and abuts against the top surface of the oil seal ring, thereby making the bottom end of the oil seal ring tightly abut against the bottom wall inside the mounting box.

[0021] To facilitate the drainage of residual water inside the installation box, a water outlet is provided on the peripheral wall of the installation box located inside the outer barrel.

[0022] In order to generate air pressure during rotation to facilitate the discharge of residual water, the outer peripheral wall of the pressure ring is provided with multiple ribs arranged at intervals along the circumference, which are directly opposite the water outlet.

[0023] To prevent water from accumulating in the groove, a drain outlet is provided on the peripheral wall of the rotating seat, which communicates with the groove.

[0024] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: an integrated water tank, including a water tank, characterized in that: it also includes the above-mentioned impeller cleaning machine, which is disposed on the water tank.

[0025] To facilitate the installation of the impeller cleaning machine, the water tank includes interconnected tank bodies and a fixed cylinder, with the outer bucket located inside the fixed cylinder.

[0026] Compared with the prior art, the advantages of this utility model are: by setting the bottom surface inside the outer tub to gradually rise from the periphery of the drain outlet to the outer periphery of the outer tub, the cleaning water inside the outer tub can be easily collected to the drain outlet for discharge, thereby reducing residual water.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] 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.

[0038] like Figures 1 to 9 The image shows a preferred embodiment of the integrated sink of this utility model. The integrated sink includes a sink 1 and a pulsator washing machine disposed on the sink 1. The pulsator washing machine includes an outer tub 2, an inner basket 3, a drive assembly 4, and a sealing ring 5.

[0039] The water tank 1 includes a tank body 11 and a fixed cylinder 12 that are connected to each other.

[0040] The outer tub 2 is located inside the fixed tube 12. Specifically, the bottom wall of the outer tub 2 has an upward-facing mounting box 21; the side wall of the outer tub 2 has a water inlet 22, and the bottom wall of the outer tub 2 has a drain outlet 23. The drain outlet 22 is covered with a filter screen 24. In this embodiment, the bottom surface inside the outer tub 2 gradually rises from the periphery of the drain outlet 23 to the outer periphery of the outer tub 2, thereby facilitating the collection of cleaning water inside the outer tub 2 to the drain outlet 23 for discharge.

[0041] The inner basket 3 is located inside the outer bucket 2. Specifically, the bottom of the inner basket 3 is provided with multiple strip-shaped drainage holes 30 arranged circumferentially, and each strip-shaped drainage hole 30 extends radially along the inner basket 3; the bottom of the inner basket 3 has a mounting groove 31, and the inner peripheral wall of the mounting groove 31 is provided with multiple circumferentially arranged driven ribs 311, and the bottom end of each driven rib 311 has a limiting block 3111; the edge of the top of the inner basket 3 is partially bent inward to form a pair of symmetrically arranged handles 32.

[0042] The drive assembly 4 is used to drive the inner basket 3 to rotate, and includes a fixed base 40, a rotating base 41 and a drive component 42.

[0043] Specifically, the fixing seat 40 is installed at the bottom of the outer barrel 2;

[0044] The rotating seat 41 is rotatably installed at the bottom of the inner cavity of the outer barrel 2, and its top can be inserted into the mounting groove 31. 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 driven ribs 311 correspond one-to-one with the channel 4110 and can pass through the corresponding channel 4110. The limiting block 3111 of each driven rib 311 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 basket 3 from rotating and rising under the action of centrifugal force and detaching from the rotating seat 41. The top of the rotating seat 41 has a groove 413, and the bottom of the rotating seat 41 has a pressure ring 414.

[0045] The driving component 42 is a motor, which is installed at the bottom of the fixed base 40. The power output shaft 421 of the motor passes through the bottom wall of the mounting box 21 and the rotating base 41 in sequence and extends into the groove 413.

[0046] The oil seal 5 is housed in the mounting box 21 and sleeved on the outer periphery of the power output shaft 421. The oil seal 5 is in sealing fit with the inner peripheral wall and bottom wall of the mounting box 21.

[0047] In addition, the groove 413 contains a nut 4131 that is threadedly connected to the power output shaft 421. The nut 4131 abuts against the bottom surface inside the groove 413, so that the pressure ring 414 extends into the mounting box 21 and abuts against the top surface of the oil seal 5. This causes the bottom end of the oil seal 5 to press tightly against the bottom wall inside the mounting box 21. On the one hand, this enables the power output shaft 421 to be driven to the rotating seat 3 to drive the rotating seat 41 to rotate, and on the other hand, it improves the sealing effect.

[0048] In order to facilitate the passage of the limiting block 3111 through the channel 4110 while preventing the inner basket 3 from easily detaching from the rotating seat 41, the width of the limiting block 3111 is denoted as W1, and the width of the channel 4110 is denoted as W2, where W1 < W2 < 1.5W1.

[0049] In order to guide the limiting block 3111 downward into the channel 4110, thereby facilitating the installation of the inner basket 3, the bottom of both sides of the limiting block 3111 has a first guide slope 3112 corresponding to the adjacent transmission block 411, and the first guide slope 3112 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 311, and the second guide slope 4111 gradually approaches the corresponding driven rib 311 from top to bottom.

[0050] In order to guide the limiting block 3111 upward into the channel 4110, thereby facilitating the disassembly of the inner basket 3, the top of both sides of the limiting block 3111 has a third guide slope 3113 corresponding to the adjacent transmission block 411. The third guide slope 3113 gradually approaches the corresponding transmission block 411 from top to bottom.

[0051] To improve the rotational stability of the inner basket 3, an annular rib 312 is provided on the top wall inside the mounting groove 31, and multiple arc-shaped ribs 412 are provided on the top wall of the rotating seat 41 at intervals along the circumference, with each arc-shaped rib 412 located on the outer periphery of the annular rib 312.

[0052] In addition, the mounting box 21 has a water outlet 211 on its peripheral wall inside the outer barrel 2, and multiple ribs 4141 are arranged circumferentially on the outer peripheral wall of the pressure ring 414. The ribs 4141 are directly opposite the water outlet 211. In this way, the ribs 4141 generate air pressure during rotation, which facilitates the discharge of residual water in the mounting box 21 through the water outlet 211. The rotating seat 41 has a drain outlet 4130 that communicates with the groove 413 on its peripheral wall, which can prevent water from accumulating in the groove 413. Similarly, the gap between adjacent arc-shaped ribs 412 can also facilitate the discharge of residual water.

[0053] The working principle of this embodiment is as follows:

[0054] (1) During installation, simply align the mounting slot 31 of the inner basket 3 with the rotating seat 41 and place it into the outer bucket 2. Under the action of gravity, the limiting blocks 3111 of each moving rib 311 will slide down the guide slope into the corresponding channel 4110 and pass through the channel 4110, thereby installing the inner basket 3 in place.

[0055] (2) During cleaning, the drive unit 42 drives the rotating seat 41 to rotate. When the transmission block 411 rotates to contact the adjacent driven rib 311, it will drive the entire inner basket 3 to rotate synchronously through the driven rib 311. At this time, the limiting block 3111 of the driven rib 311 is limited to the bottom of the adjacent transmission block 411, realizing the inverted hanging effect and preventing the inner basket 3 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.

[0056] (3) When draining, the cleaning water in the inner tub 2 is discharged through the drain outlet 23. The rotating seat 41 and the inner basket 3 continue to rotate. The residual water inside the inner basket 3, at the connection between the rotating seat 41 and the inner basket 3, and at the connection between the rotating seat 41 and the mounting box 21 is thrown into the inner cavity of the inner tub 2 under centrifugal force, and then converges along the bottom surface inside the inner tub 2 to the drain outlet 23 for discharge.

[0057] (4) When disassembling, simply hold the handle 32 and lift the inner basket 3. Under the action of the pull, the limiting blocks 3111 of each moving rib 311 can slide upward along the guide slope into the corresponding channel 4110 and pass through the channel 4110, thereby taking out the inner basket 3 and making it convenient to clean the inner basket 3.
