DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0032] The food processing machine provided by the embodiment of the present invention is as follows: Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it includes: a pulping chamber 100, including a cavity wall 110 and a cavity bottom wall formed by a bottom plate 120, the bottom plate 120 is installed in the cavity wall 110 so as to be movable up and down and is sealed with the cavity wall 110; and a driving device, used to drive the bottom plate 120 to move up and down along the cavity wall 110 to change the volume of the pulping chamber 100.

[0033] In the food processing machine, the pulping chamber 100 includes a cavity wall 110 and a cavity bottom wall formed by a bottom plate 120. The bottom plate 120 is installed in the cavity wall 110 so as to be movable up and down and is sealed with the cavity wall 110. The driving device drives the bottom plate 120 to move up and down along the cavity wall 110 to change the volume of the pulping chamber 100. During pulping, the driving device drives the bottom plate 120 to move down to the pulping position to achieve pulping of the set capacity. During cleaning, the driving device drives the bottom plate 120 to move up to the cleaning position. The edge of the bottom plate 120 will scrape off the residue on the cavity wall 110 it passes through during the upward movement. The residue that needs to be cleaned is all located in the pulping chamber 100 with the volume reduced. The amount of cleaning water required for cleaning is reduced, and the pulping chamber 100 is also easier to clean.

[0034] Moreover, the volume of the pulping chamber 100 is adjustable. By adjusting the volume of the pulping chamber 100, the pulping effect of making small-capacity slurry can be improved. In this way, the pulping effects of making small-capacity slurry, medium-capacity slurry and large-capacity slurry are all good, truly realizing wide-capacity pulping.

[0035] In an exemplary embodiment, if Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the food processor also includes: a motor 210, which is suspended under the bottom plate 120, and the motor shaft of the motor 210 passes through the bottom plate 120 and extends into the pulping cavity 100; and a crushing device, which is located in the pulping cavity 100 and installed at the end of the motor shaft. The motor 210 and the crushing device move up and down with the bottom plate 120. This solution not only has a good crushing effect during pulping, but also has a good cleaning effect during cleaning.

[0036] For example, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a heating tube 220 for heating and a temperature sensor 230 for temperature detection are also installed on the bottom plate 120.

[0037] In another exemplary embodiment, the food processor further includes: a motor, fixed below the bottom plate (not shown in the diagram of this solution), the motor shaft of the motor being detachably connected to the rotating shaft through a coupling, the rotating shaft passing through the bottom plate and extending into the pulping chamber; and a crushing device, located in the pulping chamber and mounted at the end of the rotating shaft, the crushing device and the rotating shaft moving up and down with the bottom plate, and the motor not moving up and down with the bottom plate. The coupling includes an upper coupling and a lower coupling, the upper coupling being mounted at the lower end of the rotating shaft, the lower coupling being mounted at the upper end of the motor shaft, the upper coupling and the lower coupling being detachably coupled in transmission, and this solution can flush the pulping chamber by spraying.

[0038] In an exemplary embodiment, the driving device includes an air pump 310, and a closed cavity 330 is formed below the bottom plate 120, and the air pump 310 is connected to the closed cavity 330 (refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 ), the air pump 310 pumps air from the outside into the closed cavity 330, and the bottom plate 120 rises to reduce the volume of the pulping cavity 100, and the air pump 310 pumps air from the closed cavity 330 to the outside, and the bottom plate 120 descends to increase the volume of the pulping cavity 100.

[0039] It can be that a base 380 is provided below the pulping chamber 100, and a receiving sink 340 and an annular mounting chamber 350 are provided on the base 380, the annular mounting chamber 350 is surrounded outside the receiving sink 340, the air pump 310 is located in the annular mounting chamber 350, and the receiving sink 340, the top wall of the annular mounting chamber 350, the cavity peripheral wall 110 and the bottom plate 120 are surrounded to form a closed chamber 330 (refer to Figure 1 and Figure 2 ).

[0040] For example, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the food processing machine further includes: a pulp discharge mechanism 240, which is arranged on the upper part of the cavity peripheral wall 110; a pulp receiving cup 250 and a waste water box 260, which are arranged below the pulp discharge port of the pulp discharge mechanism 240; and a water supply device 600, which is connected to the upper part of the cavity peripheral wall 110 and is used to supply water to the pulping cavity 100. The water supply device 600 includes components such as a water tank and a water pump.

[0041] Since the pulp discharge mechanism 240 is disposed on the upper portion of the cavity peripheral wall 110, the pulp receiving cup 250 and the waste water box 260 do not need to be completely located below the pulping cavity 100, thereby greatly reducing the height of the entire machine.

[0042] For example, Figures 1 to 3As shown, the food processor also includes: a control device 410, a signal transmitter 420 is arranged on the bottom plate 120, a signal receiver 430 is arranged on the cavity wall 110, and the signal receiver 430 and the air pump 310 are both connected to the control device 410. The control device 410 drives the air pump 310 to operate, and the air pump 310 pumps air into the closed cavity 330 to drive the bottom plate 120 to move upward, until the signal transmitter 420 reaches the same height position as the signal receiver 430, the control device 410 controls the air pump 310 to stop, at which time the pulping mechanism 240 is opened, and the prepared pulp in the pulping cavity 100 can be completely discharged from the pulping mechanism 240 into the pulp receiving cup 250. After the pulping is completed, the pulping mechanism 240 is closed, and the pulping cavity 100 can be cleaned at this time, and the amount of water required for one cleaning is reduced, and the amount of water stored in the water supply device can meet the needs of one pulping and multiple cleanings. When the scheme controls the bottom plate 120 to move downward, the control device 410 may control the air pump 310 to pump air out of the closed chamber 330 for a set time, and finally the periphery of the bottom plate 120 presses downward against the top wall of the annular mounting chamber 350 (a switch valve 320 may be installed on the closed chamber 330, and after the air pump 310 stops pumping air outward, the switch valve 320 is opened to balance the air pressure inside and outside the closed chamber 330, and the switch valve 320 is closed after the air pressure inside and outside the closed chamber 330 is balanced). The switch valve 320 may be opened for 1 to 10 seconds and then closed to achieve the balance of air pressure inside and outside the closed chamber 330. In this example, the pulping chamber 100 includes a pulping volume and a cleaning volume. The control device is a control board, the signal transmitter is a magnet, and the signal receiver is a Hall plate or a reed switch.

[0043] Or it could be, Figure 4 and Figure 5 As shown, a base 380 is provided below the pulping chamber 100, a receiving chamber 360 is provided on the base 380, a through hole 370 is provided on the top wall of the receiving chamber 360, and an extension tube 130 protruding downward is provided on the bottom plate 120. The extension tube 130 can be sealed and installed in the through hole 370 in an up-and-down manner, and the motor 210 is located in the extension tube 130. The air pump 310 is located in the receiving chamber 360 and outside the extension tube 130. The bottom plate 120, the cavity wall 110, the top wall of the receiving chamber 360 and the extension tube 130 are surrounded to form a closed chamber 330. In this example, the pulping chamber 100 includes a pulping volume and a cleaning volume. When the bottom plate 120 reaches the maximum position at the top, the lower end of the extension tube 130 just escapes from the through hole 370, and the bottom plate 120 cannot continue to move upward by continuing to pump air. As long as the pumping time is well controlled, the bottom plate 120 can be stopped at the maximum position at the top.

[0044] In another exemplary embodiment, Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the driving device includes an air pump 310 and a switch valve 320. A closed cavity 330 is formed below the bottom plate 120. The air pump 310 is connected to the closed cavity 330. The switch valve 320 is closed, and the air pump 310 pumps air into the closed cavity 330. The bottom plate 120 rises to reduce the volume of the pulping cavity 100. The switch valve 320 is opened, and the bottom plate 120 descends under the gravity of the hoisted motor 210, so that the volume of the pulping cavity 100 increases. In this example, the pulping cavity 100 includes a pulping volume and a cleaning volume.

[0045] It can be, for example Figure 1 and Figure 2 As shown, a base 380 is provided below the pulping chamber 100, and a receiving trough 340 and an annular mounting chamber 350 are provided on the base 380. The annular mounting chamber 350 is surrounded by the receiving trough 340, and the air pump 310 and the switch valve 320 are located in the annular mounting chamber 350. The receiving trough 340, the top wall of the annular mounting chamber 350, the cavity peripheral wall 110 and the bottom plate 120 together form a closed chamber 330.

[0046] Or it could be, Figure 4 and Figure 5 As shown, a base 380 is provided below the pulping chamber 100, a receiving chamber 360 is provided on the base 380, a through hole 370 is provided on the top wall of the receiving chamber 360, and an extension tube 130 protruding downward is provided on the bottom plate 120. The extension tube 130 can be sealed and installed in the through hole 370 in an up-and-down manner, and the motor 210 is located in the extension tube 130. The air pump 310 is located in the receiving chamber 360 and outside the extension tube 130. The bottom plate 120, the cavity wall 110, the top wall of the receiving chamber 360 and the extension tube 130 are surrounded to form a closed chamber 330. In this example, the pulping chamber 100 includes a pulping volume and a cleaning volume. When the bottom plate 120 reaches the maximum position at the top, the lower end of the extension tube 130 just escapes from the through hole 370, and the bottom plate 120 cannot continue to move upward by continuing to pump air. As long as the pumping time is well controlled, the bottom plate 120 can be stopped at the maximum position at the top.

[0047] In another exemplary embodiment, the driving device includes a crank and a connecting rod. The crank is connected to the base plate through the connecting rod. The crank drives the connecting rod to swing to achieve the rising or falling of the base plate. This implementation method has a relatively simple structure and can also achieve the purpose of this application. Its purpose does not deviate from the design concept of the present invention and will not be repeated here. It should also fall within the scope of protection of this application.

[0048] In another exemplary embodiment, the driving device is a telescopic rod, which is connected to the base plate. The telescopic rod is extended to realize the raising of the base plate, and the telescopic rod is retracted to realize the lowering of the base plate. The structure of this implementation method is also relatively simple, and it can also achieve the purpose of this application. Its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and it should also fall within the protection scope of this application.

[0049] In an exemplary embodiment, if Figures 1 to 5 As shown, a groove 121 is recessed on the peripheral end surface of the bottom plate 120 , and the sealing member is stuck in the groove 121 , and the bottom plate 120 and the cavity peripheral wall 110 are sealed and leak-proofed by the sealing member.

[0050] For example, Figures 1 to 5 As shown, the sealing member is a sealing sleeve 500, and a clamping rib 510 is protruded on the inner side of the sealing sleeve 500. The sealing member is sleeved on the peripheral end surface of the bottom plate 120, and the clamping rib 510 is clamped into the clamping groove 121 to realize the positioning of the sealing member. The upper edge of the sealing sleeve 500 is set to be flush with the upper side of the bottom plate 120, and the lower edge of the sealing sleeve 500 is set to be flush with the lower side of the bottom plate 120, which can also prevent slag (i.e., hidden residue) from being hidden between the bottom plate 120 and the cavity peripheral wall 110.

[0051] For example, sealing ribs are provided on the outer side of the sealing sleeve, and the sealing ribs can improve the sealing performance.

[0052] In another exemplary embodiment, a sealing member is coated on the periphery of the bottom plate (not shown in the figure of this solution), and a sealing member is used to seal between the bottom plate and the peripheral wall of the cavity to prevent leakage.

[0053] For example, the seal is a sealing sleeve, the inner side of which is recessed with a slot, and the peripheral end surface of the bottom plate is protruding with a rib, which is inserted into the slot to position the seal (not shown in the diagram). The upper edge of the sealing sleeve 500 is set flush with the upper side of the bottom plate, and the lower edge of the sealing sleeve is set flush with the lower side of the bottom plate to prevent the upper edge of the sealing sleeve from protruding on the upper side of the bottom plate to form a step and increase the difficulty of cleaning.

[0054] For example, sealing ribs are provided on the outer side of the sealing sleeve, and the sealing ribs can improve the sealing performance.

[0055] In another exemplary embodiment, a groove is recessed on the peripheral end surface of the base plate, and the sealing member is a sealing ring that is stuck in the groove, and the sealing member is used to seal and prevent leakage between the base plate and the peripheral wall of the cavity (not shown in this scheme).

[0056] For example, one sealing ring may be provided in the axial direction of the pulping chamber 100 , or 2 to 4 sealing rings may be provided at intervals in the axial direction of the pulping chamber 100 . Providing 2 to 4 sealing rings may better improve the sealing effect.

[0057] In an exemplary embodiment, the seal is made of wear-resistant silicone, and a coating is provided on the inner side of the cavity wall 110. The coating can be coated with a smooth, wear-resistant, self-lubricating material to better ensure the service life of the product.

[0058] It can be, for example Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the cavity wall 110 is in the shape of a cylindrical tube (or other straight tube-shaped structures, such as a rectangular tube), and the bottom plate 120 is a circular plate (or other plate-shaped structures, such as a rectangular plate).

[0059] Alternatively, the cavity wall may be a cylindrical structure with a variable inner diameter, and the bottom plate may be an elastically deformable plate with a variable area (such as a silicone plate with a variable area, the edge of the silicone plate is provided with annular support ribs with a variable diameter, and the annular support ribs always press the edge of the silicone plate against the cavity wall). This may also achieve the purpose of the present application. Its purpose does not deviate from the design concept of this practicality and will not be repeated here. It should also fall within the scope of protection of the present application.

[0060] In an exemplary embodiment, if Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the volume variation range of the pulping chamber 100 is 100ml to 2500ml, and the volume of the pulping chamber 100 is adjustable. By adjusting the volume of the pulping chamber 100, the pulping effect of making small-capacity slurry can be improved, so that the pulping effects of making small-capacity slurry, medium-capacity slurry and large-capacity slurry are all good, and wide-capacity pulping is truly realized. It can include one or more pulping volumes (multiple pulping volumes such as 500ml, 1000ml, 1500ml, 2000ml and 2500ml, etc., which can be achieved by setting multiple signal receiving components corresponding to multiple pulping volumes one by one), and it can also include one or more cleaning volumes (multiple cleaning volumes such as 100ml, 200ml and 300ml, etc.), and technicians in this field can reasonably set them according to needs.

[0061] It should be noted that the food processor disclosed in the above embodiment of the present invention has multiple functions, such as: pulping can be performed under large capacity conditions, such as a capacity range of 500ml to 2500ml, which is the pulping volume V1, and at the same time, the cavity wall can be cleaned under small capacity conditions, such as a capacity range of 100ml to 400ml, which is the cleaning volume V2. Within this pulping range, less cleaning water is used, which saves more water. In the pulping process, the food processor has the following steps:

[0062] 1) Pulping stage: the driving device drives the bottom plate to move to the pulping volume V1 to perform pulping;

[0063] 2) Cleaning stage: the driving device drives the bottom plate to move to the cleaning volume V2 for cleaning.

[0064] Of course, after the pulping stage is completed, the slurry needs to be drained to facilitate subsequent cleaning, and after the cleaning is completed, the waste water needs to be discharged.

[0065] To summarize, the food processing machine provided by the embodiment of the present invention has a pulping chamber comprising a cavity wall and a cavity bottom wall formed by a bottom plate. The bottom plate can be installed in the cavity wall so as to be movably installed up and down and is sealed with the cavity wall. The driving device drives the bottom plate to move up and down along the cavity wall to change the volume of the pulping chamber. During pulping, the driving device drives the bottom plate to move down to the pulping position to achieve pulping of the set capacity. During cleaning, the driving device drives the bottom plate to move up to the cleaning position. The edge of the bottom plate will scrape off the residue on the cavity wall it passes through during the upward movement. The residue that needs to be cleaned is all located in the pulping chamber with the volume reduced. The amount of cleaning water required for cleaning is reduced, and the pulping chamber is also easier to clean.
