Structure for preventing motor from being stuck for food pushing transmission assembly of refrigerator

Abstract

A transmission device comprises a shaft sleeve, a synchronizing wheel assembly and a spring, a driving synchronizing wheel mechanism and a driven synchronizing wheel mechanism are meshed through sawteeth, and when food materials need to be discharged, the sawteeth of the driving synchronizing wheel mechanism and the driven synchronizing wheel mechanism are tightly held and rotate synchronously, so that the food materials can be pushed to the outside. When residual food materials need to be returned to the discharging bin, the first spiral shaft conveys the food materials in the reverse direction relative to the rotating direction of the discharged food materials, and sawteeth of the driving synchronous wheel mechanism and sawteeth of the driven synchronous wheel mechanism abut against each other to rotate synchronously; when the output torsion of the power motor is larger than the friction force generated when sawteeth of the driving synchronizing wheel mechanism and the driven synchronizing wheel mechanism abut against each other, the sawteeth of the driving synchronizing wheel mechanism and the driven synchronizing wheel mechanism are separated, and the spring drives the shaft sleeve and the driven synchronizing gear 211 mechanism to move towards the tail end of the shaft sleeve due to the fact that the spring is not pressed. Therefore, high-power output of the power motor is prevented.

Description

Technical Field

[0001] The present invention relates to the technical field of intelligent kitchens, and more specifically, to an anti-motor jamming structure for a refrigerator vegetable pushing transmission component. Background Art

[0002] Ideally, users only need to remotely set the dishes they want to eat and the meal time through their mobile phones, and they can have a meal after arriving home. The intelligent kitchen can automatically set the addition order and cooking temperature of ingredients according to people's cooking habits.

[0003] Among them, an important link is that the intelligent refrigerator can dish out according to the program, controlling the dish-out order, interval time, and dish-out weight. However, when dishing out, the spiral shaft of the clean vegetable box component rotates to push out the vegetables, and the running speed is very fast, making it difficult to control the dish-out weight to the weight set by the system program of the intelligent refrigerator, thus affecting the cooking effect and taste.

[0004] Currently, the existing patent number CN214501829U discloses a device for controlling the dish-out weight of an intelligent refrigerator, which can accurately control the dish-out weight of the clean vegetable box component. The device for controlling the dish-out weight of the intelligent refrigerator includes: a clean vegetable box component, a material receiving trough component, and a vegetable pushing transmission component. The clean vegetable box component is arranged at the front end inside the intelligent refrigerator, the vegetable pushing transmission component is arranged at the rear end inside the intelligent refrigerator, and the material receiving trough component is arranged between the clean vegetable box component and the vegetable pushing transmission component. There are multiple clean vegetable box components and material receiving trough components with the same quantity and they operate in cooperation. The clean vegetable box component consists of a clean vegetable box, and the first spiral shaft of the clean vegetable box rotates to push the ingredients backward. The material receiving trough of the material receiving trough component just catches the ingredients, and the weighing sensor of the material receiving trough component weighs in real time. After reaching the weight set by the system program of the intelligent refrigerator, the weighing sensor sends a signal, and the clean vegetable box stops dishing out.

[0005] The fresh-cut vegetable box of this application further includes: an axis positioning seat and a housing. The food ingredients are placed inside the housing. The first spiral shaft is arranged at the bottom of the housing, and the axis positioning seat is arranged at the rear end of the housing to control the first spiral shaft without deviation. The vegetable pushing transmission component includes: a power motor, a synchronous belt tensioning plate, a belt, a transmission device, a second one-way cylinder, and a mounting plate. The power motor, the synchronous belt tensioning plate, and the second one-way cylinder are arranged on the back of the mounting plate. The transmission device and the belt are arranged inside the mounting plate. One transmission device corresponds to one fresh-cut vegetable box and one second one-way cylinder. The transmission device includes: a bushing 10, a synchronous pulley assembly 20, a pressure wheel 60, a spring 70, and a clutch mounting seat 40. The synchronous pulley assembly 20 is fixedly sleeved on the bushing 10. The spring 70 is arranged at the tail end of the bushing 10, and the transmission device is installed through the clutch mounting seat 40. The power motor provides mechanical energy for the belt. The power motor drives the belt to move. The synchronous belt tensioning plate plays a role in tightening or loosening the belt. The belt is arranged between the pressure wheel 60 and the synchronous pulley assembly 20. One belt connects two layers of synchronous pulley assemblies 20 to drive the two layers of synchronous pulley assemblies 20 to rotate, and the synchronous pulley assembly 20 drives the bushing 10 to rotate.

[0006] When preparing to serve the dishes, for the fresh-cut vegetable box that is ready to serve, the system program of the smart refrigerator controls the corresponding second one-way cylinder to start working. The second one-way cylinder moves forward, inserts into the tail end of the bushing 10 and engages, causing the bushing 10 to move forward, compressing the spring 70, and making the tail end of the first spiral shaft of the corresponding fresh-cut vegetable box insert into the head end of the bushing 10 and engage. There are triangular protrusions inside the head end of the bushing 10. The rotation of the bushing 10 drives the first spiral shaft to rotate, and the food ingredients are pushed backward.

[0007] During the process of serving the dishes, there will be a certain amount of residue of the food ingredients at the discharge port of the fresh-cut vegetable box. In order to prevent the accumulation of the food ingredient residues, it is necessary to convey the first spiral shaft in the direction opposite to the rotation direction of serving the dishes and return it to the discharge bin. However, the synchronous pulley assembly 20 is fixedly sleeved on the bushing 10. When the first spiral shaft stops rotating due to various situations such as a large accumulation of food ingredients or the food ingredients being too hard or too large, the synchronous pulley assembly 20 will also stop rotating. At this time, the power motor will output a greater power in an attempt to rotate the synchronous pulley assembly 20, which affects the service life of the power motor, and at the same time, the excessive power will cause the power motor to burn out. Summary of the Invention

[0008] In view of this, the present invention provides an anti-motor jamming structure for a refrigerator vegetable pushing transmission component. The transmission device includes: a shaft sleeve 10, a synchronous pulley assembly 20, and a spring 70. The synchronous pulley assembly 20 includes a driving synchronous pulley mechanism 21 and a driven synchronous pulley mechanism 22. The driving synchronous pulley mechanism 21 and the driven synchronous pulley mechanism 22 are engaged by saw teeth 30. When food ingredients need to be discharged, the saw teeth 30 of the driving synchronous pulley mechanism 21 and the driven synchronous pulley mechanism 22 are clamped to rotate synchronously. When the food ingredient residues need to be returned to the discharge bin, the first spiral shaft conveys in the direction opposite to the rotation direction of the vegetable discharging, and the saw teeth 30 of the driving synchronous pulley mechanism 21 and the driven synchronous pulley mechanism 22 are in contact to rotate synchronously. When the first spiral shaft stops rotating, when the output torque of the power motor is greater than the frictional force when the saw teeth 30 of the driving synchronous pulley mechanism 21 and the driven synchronous pulley mechanism 22 are in contact, the saw teeth 30 of the driving synchronous pulley mechanism 21 and the driven synchronous pulley mechanism 22 are disengaged, and the spring 70 drives the shaft sleeve 10 and the driven synchronous gear 211 mechanism to move towards the tail end of the shaft sleeve 10 due to the lack of compressive force, thereby preventing the high-power output of the power motor.

The synchronous pulley assembly 20 is used for sleeving with a belt, and the synchronous pulley assembly 20 rotates synchronously by driving the belt to move through a power motor. The spring 70 is sleeved around the shaft sleeve 10 and close to its tail end. The tail end of the shaft sleeve 10 is used to be connected to a second one-way cylinder when food ingredients need to be discharged, and the second one-way cylinder drives the shaft sleeve 10 to move forward, and the spring 70 is compressed. The head end of the shaft sleeve 10 is used to be connected to a first spiral shaft and rotate synchronously when food ingredients need to be discharged. The synchronous pulley assembly 20 includes a driving synchronous pulley mechanism 21 and a driven synchronous pulley mechanism 22.

Therefore, when food ingredients need to be discharged, the tail end of the shaft sleeve 10 is connected to the second one-way cylinder. The second one-way cylinder drives the shaft sleeve 10 to move forward so that the head end of the shaft sleeve 10 is connected to the first spiral shaft.

[0027] As Figures 1-3 shown, an anti-motor jamming structure of a refrigerator vegetable-pushing transmission component includes a transmission device, and the transmission device includes: a shaft sleeve 10, a synchronous pulley assembly 20 and a spring 70. The shaft sleeve 10 is sleeved on the inner ring of the synchronous pulley assembly 20. The synchronous pulley assembly 20 is used for sleeving with a belt, and the synchronous pulley assembly 20 rotates synchronously by driving the belt to move through a power motor. The spring 70 is sleeved around the shaft sleeve 10 and close to its tail end. The tail end of the shaft sleeve 10 is used to be connected to a second one-way cylinder when food ingredients need to be discharged. The second one-way cylinder drives the shaft sleeve 10 to move forward, and the spring 70 is compressed. The head end of the shaft sleeve 10 is used to be connected to a first spiral shaft and rotate synchronously when food ingredients need to be discharged. The synchronous pulley assembly 20 includes an active synchronous pulley mechanism 21 and a passive synchronous pulley mechanism 22. The active synchronous pulley mechanism 21 and the passive synchronous pulley mechanism 22 are engaged by sawteeth 30. When food ingredients need to be discharged, the sawteeth 30 of the active synchronous pulley mechanism 21 and the passive synchronous pulley mechanism 22 are clamped to rotate synchronously. When the residual food ingredients need to be returned to the discharge bin, the first spiral shaft conveys in the reverse direction of the rotation direction of the food delivery. The sawteeth 30 of the active synchronous pulley mechanism 21 and the passive synchronous pulley mechanism 22 are abutted to rotate synchronously. When the first spiral shaft stops rotating, when the output torque of the power motor is greater than the friction force when the sawteeth 30 of the active synchronous pulley mechanism 21 and the passive synchronous pulley mechanism 22 are abutted, the sawteeth 30 of the active synchronous pulley mechanism 21 and the passive synchronous pulley mechanism 22 are disengaged, and the spring 70 drives the shaft sleeve 10 and the passive synchronous gear 211 mechanism to move towards the tail end of the shaft sleeve 10 because it is not under a pressing force.

[0028] A triangular connection groove 12 is arranged inside the head end of the shaft sleeve 10, and a triangular connecting piece is arranged at the corresponding position of the first spiral shaft. When food ingredients need to be discharged, the triangular connection groove 12 at the head end of the shaft sleeve 10 is engaged with the triangular connecting piece of the first spiral shaft and rotates synchronously. The rotation of the shaft sleeve 10 drives the first spiral shaft to rotate, and the food ingredients are pushed backward. A clutch mounting seat 40 is sleeved outside the transmission device. The transmission device is installed at the clean vegetable box assembly through the clutch mounting seat 40 and is arranged corresponding to the corresponding first spiral shaft. A bearing 50 is arranged between the transmission device and the clutch mounting seat 40. A pressure wheel 60 is further arranged on the outer ring of the synchronous gear 211. The belt is arranged between the pressure wheel 60 and the synchronous gear 211. The pressure wheel 60 is used to prevent the belt from shifting.

[0029] As Figure 5As shown, the active synchronous pulley mechanism 21 includes a first connecting shaft 212 and a synchronous gear 211 fixedly sleeved outside the first connecting shaft 212. The first connecting shaft 212 is sleeved with the shaft sleeve 10, and the first connecting shaft 212 and the shaft sleeve 10 can rotate radially.

[0030] As Figure 4 shown, a plurality of card slots 11 are evenly arranged at intervals in the axial direction on the periphery of the shaft sleeve 10. The passive synchronous gear 211 mechanism includes a second connecting shaft 221. A card strip 222 corresponding to the card slot 11 is provided on the inner wall of the inner ring of the second connecting shaft 221. The card slot 11 and the card strip 222 can move axially relative to each other and can also move radially. Therefore, when food ingredients need to be discharged, the tail end of the shaft sleeve 10 is connected to the second one-way cylinder. The second one-way cylinder drives the shaft sleeve 10 to move forward so that the head end of the shaft sleeve 10 is connected to the first spiral shaft. The spring 70 is compressed, and the synchronous pulley assembly 20 and the shaft sleeve 10 can move synchronously through the synchronous belt.

[0031] As Figure 5 shown, a plurality of sawteeth 30 of the active synchronous pulley mechanism 21 surround the end face of the first connecting shaft 212 away from the head end of the shaft sleeve 10. A plurality of sawteeth 30 of the passive synchronous pulley mechanism 22 surround the end face of the second connecting shaft away from the tail end of the shaft sleeve 10. The sawteeth 30 include a clamping surface 31 and a slope surface 32. When food ingredients need to be discharged, the clamping surfaces 31 of the sawteeth 30 of the active synchronous pulley mechanism 21 and the passive synchronous pulley mechanism 22 are clamped to rotate synchronously. When the food ingredient residues need to be returned to the discharge bin, the first spiral shaft conveys in the reverse direction of the rotation direction of serving the dishes. The slope surfaces 32 of the sawteeth 30 of the active synchronous pulley mechanism 21 and the passive synchronous pulley mechanism 22 are abutted to rotate synchronously. The angle between the clamping surface 31 and the slope surface 32 of the same sawtooth 30 is greater than 30°.

[0032] Advantages of the present invention: The present invention provides an anti-motor jamming structure for a refrigerator vegetable pushing transmission component. The transmission device includes: a shaft sleeve 10, a synchronous pulley assembly 20, and a spring 70. The synchronous pulley assembly 20 includes a driving synchronous pulley mechanism 21 and a driven synchronous pulley mechanism 22. The driving synchronous pulley mechanism 21 and the driven synchronous pulley mechanism 22 are engaged by sawteeth 30. When food ingredients need to be discharged, the sawteeth 30 of the driving synchronous pulley mechanism 21 and the driven synchronous pulley mechanism 22 are tightly held to rotate synchronously. When the food ingredient residues need to be returned to the discharge bin, the first spiral shaft conveys in the direction opposite to the rotation direction of the vegetable discharging. The sawteeth 30 of the driving synchronous pulley mechanism 21 and the driven synchronous pulley mechanism 22 are in contact to rotate synchronously. When the first spiral shaft stops rotating, when the output torque of the power motor is greater than the frictional force when the sawteeth 30 of the driving synchronous pulley mechanism 21 and the driven synchronous pulley mechanism 22 are in contact, the sawteeth 30 of the driving synchronous pulley mechanism 21 and the driven synchronous pulley mechanism 22 are disengaged, and the spring 70 drives the shaft sleeve 10 and the driven synchronous gear 211 mechanism to move towards the tail end of the shaft sleeve 10 due to the absence of the pressing force, thereby preventing the high-power output of the power motor.

[0033] The above embodiments only represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
