[0040] The utility model will be further described below in combination with the drawings:

[0041] Embodiment:

[0042] The integrated sink assembly is shown in the attachedFigure 1 As shown in the accompanying drawings, the sink 1 comprises a sink body 1.1, and a storage cabinet structure connected to the sink body 1.1 for storing articles.

[0043] As shown in the accompanying drawings, the sink 1 comprises a sink body 1.1, and a storage cabinet structure connected to the sink body 1.1 for storing articles. Figure 1 As shown in the accompanying drawings, the sink 1 comprises a sink body 1.1, and a storage cabinet structure connected to the sink body 1.1 for storing articles.

[0044] The sink body 1.1 of the sink 1 is generally installed in the kitchen countertop in a flush manner. According to the conventional installation state of the sink body 1.1, it generally comprises: a front part opposite to the kitchen worker after being installed in the kitchen countertop in a flush manner; and a rear part opposite to the kitchen wall and away from the kitchen worker. There is a certain gap between the rear part of the sink and the kitchen wall, which is not easy to be touched by the worker and is often not effectively utilized, belonging to idle space.

[0045] Therefore, in the embodiment, the rear part of the sink body 1.1 is protrusively formed with: a connecting plate 1.12 horizontally extending and arranged outside the washing tank 1.11; and the cabinet body 2 is installed on the connecting plate 1.12. For example, the connecting plate 1.12 is provided with an embedded hole penetrating from top to bottom, the lower end of the cabinet body 2 is inserted into the embedded hole, and the cabinet body 2 has a support part lapping on the connecting plate 1.12 from top to bottom, so that the cabinet body 2 can be detachably embedded in the sink body 1.1.

[0046] Compared with installing the cabinet body 2 in the front part, left part or right part of the sink body 1.1 which is easy to be touched by the kitchen worker, through the above-mentioned arrangement, the collision between the kitchen worker and the cabinet body 2 can be better avoided, the space behind the sink can be effectively utilized, more space which is easy to be touched by the kitchen worker can be released, the kitchen worker can have a wider use experience, and the use experience of the kitchen with the integrated sink assembly is optimized.

[0047] Further, the cabinet body 2 has a receiving groove 2.1 with an opening facing upward; the cabinet body 3 is movably installed in the receiving groove 2.1 and is configured to be upwardly extended out of the receiving groove 2.1 by upward movement, and the cabinet body 3 has a storage groove 3.1 with an opening facing one side for storing articles.

[0048] That is, when it is needed to put the external articles into the storage groove 3.1, the cabinet body 3 can be pulled up to the position shown in the accompanying drawings by external force. Figure 4 As shown in the accompanying drawings, the storage groove 3.1 exposes the cabinet body 2 to put articles into the storage groove 3.1.

[0049] After the placement is completed, the cabinet 3 can be pushed downward into the containing groove 2.1, as shown in the accompanying Figure 2 , to achieve the storage of the articles.

[0050] In order to improve the stability of the cabinet 3 during the lifting process, the cabinet 3 and the warehouse body 2 are generally provided with a sliding connection structure, such as a drawer. For example, one side wall of the containing groove 2.1 is provided with a sliding rail extending in the vertical direction, and the outer surface of the cabinet 3 is provided with a sliding block matching the sliding rail, which is slidingly connected to the sliding rail to enable vertical lifting and sliding, thereby enabling the cabinet 3 to be lifted and moved more stably in the vertical direction.

[0051] Further, in combination with the installation environment of the sink 1, in order to facilitate the taking and placing of articles, as shown in the accompanying Figure 1 , the cabinet 3 has a side surface facing the washing tank 1.11, and the article placing groove 3.1 is arranged on the side surface with an opening facing the washing tank 1.11. This enables the kitchen worker working in the front area of the tank body 1.1 to more conveniently place and take articles.

[0052] Further, considering that when using the sink 1 for washing, water splashes often occur, which can easily fall into the containing groove 2.1 from the opening of the containing groove 2.1, thereby eroding the articles in the containing groove 2.1.

[0053] Therefore, as shown in the accompanying Figure 1 and the accompanying Figure 2 , the present embodiment further provides a top cover plate 3.2 at the upper end of the cabinet 3, which is sized to fit the size of the opening of the containing groove 2.1, so that, as shown in the accompanying Figure 2 , when the cabinet 3 is placed in the containing groove 2.1, the top cover plate 3.2 is placed on the warehouse body 2 to cover the opening of the containing groove 2.1, thereby preventing water splashes in the sink 1 from falling into the containing groove 2.1.

[0054] As shown in the accompanying Figure 1 , in order to improve the convenience of placing articles into the article placing groove 3.1 or taking articles out of the article placing groove 3.1, the article placing groove 3.1 has two side walls placed on both sides thereof in the horizontal direction, one of which can be recessed to form a first notch 3.11 in communication with the opening, and the other of which can be recessed to form a second notch 3.12 in communication with the opening, to increase the operable space when articles are taken out. The specific size of the first notch 3.11 and the second notch 3.12 is set according to actual needs.

[0055] On the basis of the above-mentioned scheme, in order to better prevent water in the sink 1 from falling into the containing groove 2.1, as shown in the accompanying Figure 1As shown in the drawings, the cabinet 2 in the embodiment has a part placed above the connecting plate 1.12, so that the slot opening of the accommodating groove 2.1 is higher than the connecting plate 1.12.

[0056] In order to improve the convenience of lifting movement of the cabinet 3, as shown in the drawings, the cabinet 3 is spaced apart from the groove bottom of the accommodating groove 2.1, and a lifting device 4 connected with the cabinet 3 is arranged between the cabinet 3 and the groove bottom of the accommodating groove 2.1, and is used to drive the cabinet 3 to move up and down. Figure 2

[0057] The cabinet 3 is driven by the lifting device 4 to rise to expose the cabinet 2, and the articles can be put into or taken out of the article accommodating groove 3.1.

[0058] And the cabinet 3 is driven by the lifting device 4 to drop to the state shown in the drawings, that is, to keep the conventional storage state. Figure 2

[0059] The lifting device 4 can be a common push rod motor or a push rod cylinder. By fixing the cabinet 3 with the push rod piston of the push rod motor, the cabinet 3 can be driven to move up and down by the lifting movement of the push rod piston. However, directly fixing the cabinet 3 on the push rod piston will cause excessive load pressure, which will shorten the service life.

[0060] Therefore, the lifting device 4 in the embodiment preferably does not directly press the cabinet 3 on the structure of the rotating motor 4.3.

[0061] Specifically, as shown in the drawings, the lifting device 4 in the embodiment mainly comprises a rotating shaft 4.1, a sleeve 4.2 and a rotating motor 4.3. Figure 3 Specifically, as shown in the drawings, the rotating shaft 4.1 is a shaft member with a vertical axis arranged in a vertical direction to extend in the vertical direction, and the lower end of the rotating shaft 4.1 is rotatably connected to the cabinet 2, so that the rotating shaft 4.1 can rotate around the vertical axis arranged in the vertical direction.

[0062] Figure 2 At the same time, the sleeve 4.2 is sleeved on the outer periphery of the rotating shaft 4.1, and the inner wall of the sleeve 4.2 and the outer periphery of the rotating shaft 4.1 are connected by threads, so that the sleeve 4.2 can be driven to move up and down by the rotation of the rotating shaft 4.1; and the upper end of the sleeve 4.2 is connected with the cabinet 3. Figure 3

[0063]

[0064] ​​​​​The rotary motor 4.3 is located at the bottom of the receiving groove 2.1 and is fixed to the chamber 2 by means of, for example, screws. The rotary motor 4.3 has an output shaft 4.31 that outputs rotational power by rotating. The output shaft 4.31 is driven to the rotating shaft 4.1 so that: by rotating the output shaft 4.31 forward or reverse, it drives the rotating shaft 4.1 to rotate and drive the sleeve 4.2 to rise or fall.

[0065] That is, the rotating motor 4.3 is a motor whose output shaft 4.31 can rotate both forward and reverse. When the output shaft 4.31 rotates forward, it drives the rotating shaft 4.1 to rotate, thereby causing the sleeve 4.2 to rise and the cabinet 3 to rise. By driving the output shaft 4.31 to rotate in reverse, the rotating shaft 4.1 can be driven to rotate in the opposite direction, thereby causing the sleeve 4.2 to fall and the cabinet 3 to fall.

[0066] At this point, an upward button for controlling the forward rotation of the output shaft 4.31 and a downward button for controlling the reverse rotation of the built-in output shaft 4.31 can be installed at the upper end of the cabinet 2. The upward button is electrically connected to the rotating motor 4.3 and is used to control the output shaft 4.31 to rotate forward a certain number of times (the specific number of rotations is set according to the required lifting and lowering stroke of the cabinet 3). The downward button is electrically connected to the rotating motor 4.3 and is used to control the output shaft 4.31 to rotate backward the same number of times. When the sink assembly is installed and the rotating motor 4.3 is electrically connected to the power supply, the upward and downward buttons can be used to control the lifting and lowering of the cabinet 3 according to the needs of item placement, as described above.

[0067] The output shaft 4.31 of the rotating motor 4.3 can be connected to the rotating shaft 4.1 by a gear set structure or a transmission belt structure.

[0068] In this embodiment, as shown in the appendix Figure 3 and attached Figure 4 As shown, a worm gear, which offers stable transmission and a simple structure, is used for the transmission connection. Specifically, the output shaft 4.31 of the rotating motor 4.3 extends laterally, and its outer circumference is provided with helical teeth 4.32 extending along its axial direction. A transmission gear 4.4 is fixedly fitted onto the outer circumference of the rotating shaft 4.1. The helical teeth 4.32 mesh with the transmission gear 4.4, so that the output shaft 4.31 is drivenly connected to the rotating shaft 4.1.

[0069] Furthermore, the upper end of the sleeve 4.2 can be directly fixed to the lower end of the cabinet 3. However, this would reduce the mobility of the cabinet 3, which can only move along the lifting trajectory of the sleeve 4.2. If the cabinet 3 is not installed very precisely, it is easy to get stuck.

[0070] Based on this, as attached Figure 2As shown, in the embodiment, the upper end of the sleeve 4.2 is rotatably connected to the cabinet body 3 by, for example, a pin connection structure, so that the sleeve 4.2 and the cabinet body 3 can be relatively rotated to avoid being directly fixed and clamped, thereby reducing the possibility of clamping of the cabinet body 3.

[0071] Further, as shown in the accompanying drawings, Figure 3 and 4 As shown, the outer periphery of the sleeve 4.2 can also be provided with a protective shell 4.5 wrapped thereon, and the protective shell 4.5 can be fixedly connected to the bin body 2. The sleeve 4.2 is movably installed in the protective shell 4.5, and the top of the protective shell 4.5 has a clearance hole 4.51 for the sleeve 4.2 to extend out, so as to form protection for the sleeve 4.2 and ensure that it can stably ascend and descend.

[0072] On the basis of the above-mentioned scheme, considering that the bin body 2 is easy to be wet when placed on the side of the cleaning tank 1.11, or that the bin body 2 is easy to be excessively humid and cause bacteria breeding when the cabinet body 3 is placed with freshly washed articles.

[0073] Based on this, as shown in the accompanying drawings, Figure 5 As shown, in the embodiment, the bin body 2 is additionally connected with a fan housing 5 on the outer surface thereof, and the fan housing 5 is formed with a flow guide cavity 5.1 around the outer surface of the bin body 2. A plurality of overflow holes 2.11 are arranged on the side wall of the accommodating groove 2.1 at positions matched with the fan housing 5, and the accommodating groove 2.1 is connected in communication with the flow guide cavity 5.1 through the plurality of overflow holes 2.11. The fan housing 5 has a wind guide hole 5.2 for the flow guide cavity 5.1 to communicate with the outside space. A fan 6 is arranged in the flow guide cavity 5.1, and is configured to form an air flow that is blown from the accommodating groove 2.1 to the wind guide hole 5.2.

[0074] The fan 6 is a commonly used axial fan or centrifugal fan, which mainly includes a rotating motor fixedly connected to the bin body 2 or the fan housing 5 and used to provide rotating power, and a blade fixedly connected to the output shaft of the rotating motor. When the rotating motor drives the blade to rotate to make the fan operate, the fan 6 has an air inlet side and an air outlet side. The air inlet side is arranged to face the overflow hole 2.11, and the air outlet side is arranged to face the wind guide hole 5.2, so as to realize that when the fan 6 operates, the air flow that is blown from the accommodating groove 2.1 to the wind guide hole 5.2 can be formed.

[0075] Through the action of the fan 6, the humid air in the accommodating groove 2.1 can be blown out from the accommodating groove 2.1 along the air flow, thereby improving the dryness of the accommodating groove 2.1.

[0076] As shown in the accompanying drawings, Figure 5 The fan housing 5 is preferably arranged at the lower end of the bin body 2, and the overflow hole 2.11 is arranged on the groove bottom surface of the accommodating groove 2.1, so as to be combined with the action of gravity to discharge the humid air or even water droplets in the accommodating groove 2.1 outwardly.

[0077] At this time, a switch button can be arranged at the upper end of the bin body 2, which is electrically connected to the rotating motor of the fan 6, so that the fan 6 can be controlled to be turned on / off after the sink assembly is installed and the rotating motor of the fan 6 is connected to the power supply.

[0078] Alternatively, after the sink assembly is installed and the rotating motor of the fan 6 is connected to the power supply, the fan 6 is kept in a long-term open state.
