Technical Field
[0001] This utility model belongs to the field of kitchen equipment technology, and specifically relates to a sink. Background Technology
[0002] To effectively utilize the space within the sink, a tray is placed inside the sink body to realize the concept of a sink within a sink. Specific examples include the structures disclosed in Chinese invention patent application number 201611033296.2, "Integrated Cleaning Sink" (authorization announcement number CN106522321B), and Chinese utility model patent application number 202220739391.9, "An Integrated Sink" (authorization announcement number CN217267850U).
[0003] In order to enable the washing of food in the tray without interfering with the washing of food in the sink, an independent water inlet and drainage component needs to be introduced into the tray. The water inlet and drainage component is usually located at the rear of the sink. When water inlet and drainage are needed, the end of the water pipe in the water inlet and drainage component is introduced forward into the tray. After the water inlet and drainage are completed, the end of the water pipe needs to move backward to return to the initial position. At this time, the end of the water pipe is detached from the tray, and the tray can be taken out by the user and detached from the sink.
[0004] However, the limited space at the rear of existing sink bodies makes the installation of inlet and outlet components difficult. Furthermore, to drive the water pipes back and forth, the inlet and outlet components typically include a drive mechanism. The design of this drive mechanism must consider how to achieve the back-and-forth movement of the water pipes within the limited space. Additionally, when there are two or more water pipes, such as inlet and outlet pipes, existing technologies generally use a corresponding number of drive mechanisms to move each pipe sequentially (e.g., the inlet pipe first enters the tray for water intake, and after cleaning, the outlet pipe then enters the tray for drainage). This undoubtedly increases cost and installation difficulty. Utility Model Content

[0050] The utility model will be described in further detail below in combination with the embodiment of the drawings.
[0051] As Figures 1 to 16 shown, it is a preferred embodiment of the sink of the utility model, which comprises a sink body 1, a tray 2 and a module.
[0052] The sink body 1 is internally hollow to form a cavity 10 with a top opening and a bottom with a water hole, and the side of the sink body 1 facing the user is the front side.
[0053] The tray 2 is arranged at the top opening of the cavity 10 and can be separated upward from the sink body 1, and the rear side wall of the tray 2 is provided with a through hole 20.
[0054] The above-mentioned module is arranged at the rear side of the sink body 1 and comprises a box body 5, a water pipe 3 arranged in the box body 3, a driving mechanism and a strain gauge 6. Among them, the box body 5 is provided with a hole corresponding to the position of the front end of the water pipe 3. The water pipe 3 is arranged in the box body 5 in a manner that it can move forward and backward relative to the rear side wall of the tray 2, and under the driving of the driving mechanism, it can move forward to the end of the water pipe 3 extending into the through hole 20 or can move backward to the end of the water pipe 3 extending out of the through hole 20. The driving mechanism comprises a transmission member 4 and a power member for driving the transmission member 4 to move up and down, the transmission member 4 is provided with a chute 40 extending up and down and inclined forward and backward, and the water pipe 3 is provided with a sliding block capable of moving along the chute 40, so that the transmission member 4 and the water pipe 3 are constrained together and the up and down movement of the transmission member 4 can drive the water pipe 3 to move forward and backward.
[0055] In this embodiment, there are three through holes 20. There are three water pipes 3: two inlet pipes 31 and one drain pipe 32. The two inlet pipes 31 are located on the left and right sides above the drain pipe 32, and the two inlet pipes 31 are mounted on the same mounting base 310. The two inlet pipes 31 and the drain pipe 32 are respectively set with corresponding through holes 20. There are four sliding grooves 40: two first sliding grooves 41 arranged on the left and right sides of the mounting base 310, and two second sliding grooves 42 arranged on the left and right sides between the two first sliding grooves 41. Each first sliding groove 41 has a vertically extending first vertical section 411 and a first inclined section 412 extending downward and backward from the lower end of the first vertical section 411. Each second sliding groove 42 has a vertically extending second vertical section 421 and a second inclined section 422 extending upward and forward from the upper end of the second vertical section 421. The upper end of the second vertical segment 421 is at the same height as the lower end of the first vertical segment 411; the lower end of the first inclined segment 412 and the lower end of the second vertical segment 421 are at the same height; the upper end of the first vertical segment 411 and the upper end of the second inclined segment 422 are at the same height. There are four sliders: two first sliders 311 located on the left and right sides of the mounting base 310 and corresponding to their respective first sliding grooves 41; and two second sliders 321 located on the left and right sides of the drain pipe 32 and corresponding to their respective second sliding grooves 42. Thus, the cooperation between the sliders and the sliding grooves constrains the water pipe and the transmission component 4 together, and the up-and-down movement of the transmission component 4 drives the water pipe to move back and forth.
[0056] In this embodiment, the inlet pipe 31 and the outlet pipe 32 switch sequentially between the initial state, the inlet state, and the outlet state under the action of the same power component and the transmission component 4.
[0057] like Figures 2 to 5 As shown, the initial state is as follows: the end of the water inlet pipe 31 and the end of the drain pipe 32 both extend out of their respective through holes 20. At this time, the first slider 311 is located at the lower end of the first inclined section 412, and the second slider 321 is located at the lower end of the second vertical section 421.
[0058] like Figures 6 to 11 As shown, the water inlet state is as follows: the end of the water inlet pipe 31 extends into the corresponding through hole 20, and the end of the drain pipe 32 extends out of the corresponding through hole 20. At this time, the first slider 311 is located at the lower end of the first vertical section 411, and the second slider 321 is located at the upper end of the second vertical section 421.
[0059] like Figures 12 to 16 As shown, the drainage state is as follows: the end of the inlet pipe 31 and the end of the drain pipe 32 are both inserted into their respective through holes 20. At this time, the first slider 311 is located at the upper end of the first vertical section 411, and the second slider 321 is located at the upper end of the second inclined section 422.
[0060] In the initial state, when the transmission member starts to move downward to the first position, the second slider 321 moves upward relative to the second vertical section 421 to keep the position of the drain pipe 32 unchanged, and the first slider 311 moves upward relative to the first inclined section 412, so that the two water inlet pipes 31 connected to the first slider 311 move forward synchronously to extend out of the box body 5 and into the through hole 20 on the corresponding tray 1, at this time, the tray starts to fill with water.
[0061] When the transmission member continues to move downward to the second position, the second slider 321 moves upward relative to the second inclined section 422, so that the drain pipe 32 connected to the second slider 321 moves forward to extend out of the box body 5; the first slider 311 moves upward relative to the first vertical section 411 to keep the position of the two water inlet pipes 31 unchanged, maintaining the posture of extending out of the box body 5, at this time, the two water inlet pipes 31 and the drain pipe 32 all extend out of the box body 5 and into the through hole 20 on the corresponding tray 1, at this time, the tray starts to drain water through the drain pipe.
[0062] After the drainage is completed, driving the transmission member to move downward can make the drain pipe 32 and the water inlet pipe 31 extend backward to the corresponding through hole 20 and then retract into the box body 5.
[0063] Therefore, the embodiment can realize the sequential actions of the water inlet pipe 31 and the drain pipe 32 through one driving mechanism.
[0064] In order to drive the transmission member 4 to move up and down, a vertical rack 43 is arranged on the transmission member 4, and a gear 44 engaged with the rack 43 is arranged. The power member is an existing motor, which is used to drive the gear 44 to rotate and then drive the rack 43 and the transmission member 4 to move up and down.
[0065] At the same time, in order to avoid damage to the water pipe and other components caused by artificially lifting the tray upward when the water pipe extends forward, in the embodiment, as shown in Figure 9 , a strain gauge 6 is arranged on the water pipe 3, and a controller connected to the strain gauge 6 is arranged, and the controller is connected to the power member. When the water pipe extends forward, if the tray 2 is lifted upward artificially, the tray 2 will apply an external force to the water pipe 3 in the upward and downward direction, at this time, the strain gauge 6 on the water pipe 3 will be deformed and transmit a signal to the controller, and the controller controls the power member to work to retract the water pipe 3 backward to prevent damage.
[0066] In the embodiment, in order to realize water inlet or drainage of the water pipe, the rear end of the water pipe can be connected to a flexible hose.
[0067] And in order to avoid the water in the tray from leaking out of the through hole corresponding to the drain pipe 32 in the initial state or the water inlet state, the embodiment is provided with a valve 21 on the through hole corresponding to the drain pipe 32, the valve 21 closes the through hole in the normal state, after the front end of the drain pipe 32 extends into the through hole 20, the valve 21 is opened by the drain pipe, at this time, the water in the tray can be smoothly drained.
