Description

Technical Field

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

[0002] Current integrated sinks combine multiple products that are spatially or functionally related to the sink, including washing machines, water purifiers, garbage disposers, and sterilizers.

[0003] For example, the Chinese patent application number CN202220745881.X, entitled "A Kitchen Utensil Sterilizer and Integrated Sink", discloses a technical solution that combines a kitchen utensil sterilizer and a sink into one unit.

[0004] However, in the above scheme, both the cleaning chamber and the disinfection chamber are open, and external impurities can easily enter their inner chambers through the top opening and cause contamination. However, if a cover structure is directly installed on the top of the disinfection chamber, it is more troublesome to open the cover without a handle.

[0005] In addition, existing push rod mechanisms are often used in areas such as controlling the opening and closing of doors, but the drive components are prone to damage due to stalling, which can cause the push rod mechanism to fail. Utility Model Content

[0006] The first technical problem to be solved by this utility model is to provide a push rod mechanism that can avoid damage to the driving component due to stalling, in light of the current state of the technology.

[0007] The second technical problem to be solved by this utility model is to provide an integrated water tank that uses the above-mentioned push rod mechanism.

[0008] The third technical problem to be solved by this utility model is to provide an integrated water tank that can automatically assist in opening the lid.

[0009] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a push rod mechanism, including a fixed seat;

[0010] A top rod, extending vertically and movably mounted on the fixed base; and

[0011] A drive assembly is used to drive the push rod upward.

[0012] Its characteristic is that: the driving component includes...

[0013] The drive shaft has a first clutch element at its end;

[0014] The driven shaft is arranged coaxially with the driving shaft, rotatably mounted on the fixed seat and slidably along its axial direction, and has a second clutch at its end that can engage and disengage with the first clutch.

[0015] The second elastic element acts between the driven shaft and the fixed seat so that the second clutch and the first clutch always tend to mesh with each other.

[0016] A transmission assembly, acting between the driven shaft and the push rod, converts the rotational motion of the driven shaft into the up-and-down movement of the push rod; and

[0017] A driving component is used to drive the drive shaft to rotate.

[0018] In order to convert the rotational motion of the driven shaft into the up-and-down movement of the push rod, the transmission assembly includes:

[0019] A traction seat is connected to the side of the top rod;

[0020] A steering seat, located directly above the traction seat and spaced apart on one side of the driven shaft; and

[0021] The first end of the pull rope is wound around the driven shaft, and the second end passes over the steering seat and is positioned on the traction seat.

[0022] To ensure that the top rod returns to its original position promptly after the rope is unwound, a first elastic element is also included. This first elastic element acts between the top rod and the fixed seat so that the top rod always has a downward tendency to move.

[0023] To facilitate the installation of the first elastic element, a first limiting protrusion is provided on the outer peripheral wall of the top rod. The first elastic element is a compression spring, which is sleeved on the outer periphery of the top rod, and the two ends of the compression spring respectively abut against the opposite surfaces of the first limiting protrusion and the fixing seat.

[0024] To facilitate the installation of the second elastic element, a second limiting protrusion is provided on the outer peripheral wall of the driven shaft. The second elastic element is a compression spring, which is sleeved on the outer periphery of the driven shaft, and the two ends of the compression spring respectively abut against the opposite surfaces of the second limiting protrusion and the fixing seat.

[0025] To ensure stability when the first and second clutches are engaged, the first and second clutches are toothed discs that can mesh with each other.

[0026] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: an integrated water tank, characterized in that: the above-mentioned top rod mechanism is applied.

[0027] To solve the third technical problem mentioned above, it also includes

[0028] The tank body has an open-top cleaning chamber and a disinfection chamber inside; and

[0029] The cover plate structure is hinged to the groove body and can cover the top opening of the disinfection chamber;

[0030] The aforementioned push rod mechanism is used to push the cover plate structure covering the top opening of the disinfection chamber to flip upward.

[0031] To enable independent opening and closing of the cleaning chamber and disinfection chamber using a single cover structure, the disinfection chamber is located behind the cleaning chamber. Pins extending in the left-right direction are located on both sides of the tank between the cleaning and disinfection chambers. The cover structure includes multiple folding plates that are sequentially hinged in the front-back direction. The left and right ends of the rear edge of the rearmost folding plate are rotatably connected to corresponding pins. Adjacent folding plates can be unfolded or folded relative to each other, so that the integrated water tank has at least two states:

[0032] In the first state, the cover structure is in a fully folded state and covers the top opening of the disinfection chamber;

[0033] In the second state, the cover structure is fully extended and covers the top opening of the cleaning chamber.

[0034] In order to support the folding structure, the tank has support platforms on the left and right side walls of the cleaning chamber and the disinfection chamber, respectively, for the edges of the left and right sides of the folding plate to rest on.

[0035] In the first state, the edges of the lowermost folding plate rest on the corresponding support platforms on the left and right sides.

[0036] In the second state, the edges of the left and right sides of each of the folding plates rest on the corresponding support platforms.

[0037] In order to facilitate the installation of the push rod mechanism and improve the aesthetics, the push rod mechanism is installed below the support platform located on one side of the disinfection chamber, and the support platform is provided with a clearance hole for the push rod to extend out.

[0038] When the push rod is retracted, the end face of the top of the push rod is flush with the edge of the relief hole on the support platform.

[0039] To achieve the hinge between adjacent folded plates, the adjacent side edges of two adjacent folded plates are connected by a flexible hinge.

[0040] Compared with the prior art, the advantages of this utility model are:

[0041] (1) A first clutch and a second clutch capable of engaging and disengaging are provided between the drive shaft and the driven shaft of the drive assembly. The first clutch and the second clutch mesh with each other under the elastic force of the second elastic element. In this way, when the push rod moves to the limit position, if the drive unit continues to operate, the second clutch will overcome the elastic force of the second elastic element and disengage from the first clutch under the pushing action of the first clutch, thus avoiding damage to the drive unit due to stalling and causing the entire push rod mechanism to fail.

[0042] (2) By hinged to the cover plate structure on the tank and pushed by the top rod mechanism to flip the cover plate structure at the top opening of the disinfection chamber upward, automatic assisted opening of the cover can be achieved, and the cover can be opened easily without the need for a handle.

Specifically, the second drainage pipe 81 is located outside the tank 1, with its inlet end connected to the second drainage port 1022 and its outlet end connected to the side of the first drainage pipe 71; the drainage valve 82 is installed on the second drainage pipe 81 and is used to control the opening and closing of the second drainage pipe 81.

[0065] The push rod mechanism 9 is used to push the cover plate structure 2 covering the top opening of the disinfection chamber 102 to flip upward. It includes a fixed seat 91, a push rod 92, a first elastic element 93, and a drive assembly 94. Specifically, the fixed seat 91 is a hollow shell and is installed below the support platform 12 located on the right side of the disinfection chamber 102; the push rod 92 extends vertically and is movably installed in the fixed seat 91. The push rod 92 can extend out of the support platform 12 through the clearance hole 121, and a first limiting protrusion 921 is provided on the outer peripheral wall of the push rod 92; the first elastic element 93 is a compression spring, which is sleeved on the outer periphery of the push rod 92, and the two ends of the compression spring abut against the first elastic element 93. On the opposing surfaces of a limiting protrusion 921 and a fixed seat 91, the push rod 92 always tends to move downwards; the drive assembly 94 is located inside the fixed seat 91 and is used to drive the push rod 92 to move up and down to achieve extension and retraction. When the push rod 92 is retracted, the end face of the top of the push rod 92 is flush with the edge of the support platform 12 located around the relief hole 121, while the extended push rod 92 can push the cover plate structure 2 covering the top opening of the disinfection chamber 102 upwards.

[0066] In this embodiment, the drive assembly 94 includes a drive shaft 941, a driven shaft 942, a second elastic element 943, a traction seat 944, a steering seat 945, a pull rope 946, and a drive element 947. Specifically, the end of the drive shaft 941 has a first clutch element 9411; the driven shaft 942 is coaxially arranged with the drive shaft 941 and is rotatably and slidably mounted on the fixed seat 91. The end of the driven shaft 942 has a second clutch element 9421 that can engage and disengage with the first clutch element 9411, and a second limiting protrusion 9422 is provided on the outer peripheral wall of the driven shaft 942. The first clutch element 9411 and the second clutch element 9421 are toothed discs that can mesh with each other; the second elastic element 943 is a compression spring, which is sleeved on the outer periphery of the driven shaft 942, and the two ends of the compression spring abut against the second limiting protrusion 9422 respectively. On the opposite surface of the fixed seat 91, the second clutch 9421 and the first clutch 9411 are always inclined to mesh with each other; the traction seat 944 is connected to the side of the push rod 92; the steering seat 945 is mounted on the outer wall of the fixed seat 91, located directly above the traction seat 944, and spaced apart on one side of the driven shaft 942; the first end of the pull rope 946 is wound around the driven shaft 942, and the second end of the pull rope 946 passes around the steering seat 945 and is limited to the traction seat 944; the drive member 947 is a motor, connected to the inner wall of the fixed seat 91, and its power output shaft is coaxially connected to the drive shaft 941 to drive the drive shaft 941 to rotate.

[0067] When the drive unit 947 is started to rotate forward, it drives the drive shaft 941 to rotate forward. Due to the engagement of the second clutch 9421 and the first clutch 9411 under the elastic force of the second elastic element 94, the driven shaft 942 rotates synchronously, so that the pull rope 946 is wound onto the driven shaft 942, and then drives the push rod 92 to move upward through the traction seat 944. When the drive unit 947 is started to rotate in reverse, it drives the drive shaft 941 to rotate in reverse. Due to the engagement of the second clutch 9421 and the first clutch 9411 under the elastic force of the second elastic element 94, the driven shaft 942 rotates synchronously, so that the pull rope 946 is unwound from the driven shaft 942, and the push rod 92 moves downward under the elastic force of the first elastic element 93.

[0068] In this embodiment, when the push rod 92 moves to the limit position, if the drive member 947 continues to operate, the second clutch member 9421 will overcome the elastic force of the second elastic member 94 and disengage from the first clutch member 9411 under the pushing action of the first clutch member 9411, thus avoiding damage to the drive member 947 due to stalling and causing the entire push rod mechanism 9 to fail.

[0069] The working principle of this embodiment is as follows:

[0070] (1) When it is necessary to clean kitchen utensils, simply fold each folding panel 21 backward manually to switch the integrated sink to the first state. At this time, as Figure 1 As shown, the cover structure 2 is in a fully folded state and covers the top opening of the disinfection chamber 102. The edges of the left and right sides of the folded plate 21 at the bottom rest on the corresponding support platform 12, thereby hiding the disinfection chamber 102. On the one hand, it can prevent external impurities from contaminating the disinfection chamber 102. On the other hand, the cover structure 2 can be used as a storage platform, increasing the operating space of the platform connected to the tank.

[0071] At this time, the user can place kitchen utensils in the cleaning chamber 101, and then supply water to the cleaning chamber 101 through the water outlet 32 ​​to achieve the cleaning function;

[0072] (2) When it is not necessary to clean kitchen utensils, simply use the push rod mechanism 9 to push the cover structure 2 covering the top opening of the disinfection chamber 102 upwards at a certain angle (e.g., Figure 4 (As shown), then manually unfold each folding plate 21 forward to switch the integrated water tank to the second state. At this time, as shown... Figure 5 As shown, the cover structure 2 is in a fully unfolded state and covers the top opening of the cleaning chamber 101. The edges of each folded plate 21 on the left and right sides rest on the corresponding support platform 12, thereby hiding the cleaning chamber 101. On the one hand, it can prevent external impurities from contaminating the cleaning chamber 101. On the other hand, the cover structure 2 can be used as a storage platform, increasing the operating space of the platform connected to the tank.

[0073] (3) When kitchen utensils need to be disinfected, the user can place the utensils on the drain rack 1026 inside the disinfection chamber 102, and then manually fold each folding plate 21 backward to switch the integrated sink to the desired state. Figure 1 The first state shown;

[0074] Next, the water inlet valve 42 is opened, and the cleaning water is delivered to the aeration plate 53 through the water inlet pipe 41, and then supplied to the disinfection chamber 102 through each aeration hole 531 to soak the kitchen utensils.

[0075] When the liquid level in the disinfection chamber 102 reaches the set value, the water inlet valve 42 is closed and the first blower 52 is started. The gas in the upper part of the disinfection chamber 102 is transported to the aeration disc 53 through the first air supply pipe 51 and aerated to the liquid in the lower part of the disinfection chamber 102 through each aeration hole 531 to promote fluid turbulence and thus improve the cleaning effect.

[0076] After cleaning, turn off the first fan 52 and open the drain valve 82. The wastewater in the disinfection chamber 102 is discharged into the first drain pipe 71 through the second drain pipe 81.

[0077] After drainage is completed, the drain valve 82 is closed, the second fan 62 and the heating element 63 are started, and the gas in the upper part of the disinfection chamber 102 is heated by the heating element 63 through the second air supply pipe 61 and then transported to the aeration plate 53. It is then blown evenly onto the kitchen utensils through each aeration hole 531. After multiple cycles, the temperature in the disinfection chamber 102 gradually rises, achieving the drying and disinfection of the kitchen utensils.

[0078] It is worth noting that since the aeration component 5 and the drying component 6 share the same flow channel, and the water inlet 1021 and the air inlet 1023 share the same opening, on the one hand, the structure can be simplified, and on the other hand, in addition to the aeration process, the cleaning water and hot air can be evenly supplied to the disinfection chamber 102 through the aeration disc 53, which can promote the cleaning and drying processes.
