Description

Technical Field

[0001] The invention belongs to the field of food processing machines, and in particular relates to a food processing machine which can fully automatically make pulp and fully automatically clean without requiring hand washing. Background Art

[0002] Existing food processing machines generally include a main unit, a processing chamber, and a valve body assembly connected to the pulp outlet on the processing chamber. The control module in the main unit controls the motor to drive the valve body assembly to open and close the pulp outlet to achieve automatic pulp discharge and discharge of wastewater after cleaning the processing chamber. Since both pulp and waste are discharged from the pulp outlet, fine particles in the liquid are easily retained in the valve body assembly, and viscous liquid is easily attached to the surface of the valve core, resulting in accumulation of residue and residue in the valve body assembly, which is easy to breed bacteria. Although the wastewater automatically cleaned by the food processor after pulping is completed is discharged from the valve body assembly and can naturally flush the valve group, how to thoroughly flush the inside of the valve body assembly without manual operation by the user is still an urgent problem to be solved. Summary of the Invention

[0003] The object of the present invention is to provide a food processing machine which can automatically make and clean pulp without user intervention and can clean thoroughly.

[0004] In order to solve the above technical problems, the present invention provides a food processor that does not require hand washing, including a main unit and a processing chamber. The processing chamber is provided with a crushing knife driven by a motor, and the processing chamber is provided with a slurry outlet. It also includes a valve body assembly and a valve group drive unit connected to the slurry outlet. The valve group drive unit drives the valve body assembly to open or close the slurry outlet. The valve body assembly includes a valve shell and a valve core arranged in the valve shell, wherein a cleaning space is provided in the valve body assembly for water to flow through and automatically clean the valve body assembly. The valve group drive unit drives the valve core to rotate and change the water flow path in the cleaning space.

[0005] Furthermore, a valve sleeve is provided between the valve core and the valve housing, and the cleaning space includes a first cleaning space provided between the valve core and the valve sleeve.

[0006] Furthermore, the cleaning space further includes a second cleaning space provided between the valve sleeve and the valve housing, and the second cleaning space is located outside the first cleaning space.

[0007] Furthermore, the first cleaning space is provided with a first flow channel, the second cleaning space is provided with a second flow channel, and the valve sleeve is provided with a connecting port, and the first flow channel is connected with the second flow channel through the connecting port to form a circulating flow channel.

[0008] Furthermore, the valve housing is provided with a water inlet connected to a water source or a water tank, and the valve body assembly also includes a slurry outlet, and the water inlet is connected to the slurry outlet through the circulation channel.

[0009] Furthermore, the circulation flow channel includes a first circulation flow channel formed when the valve body assembly opens the slurry outlet, and a second circulation flow channel formed when the valve body assembly closes the slurry outlet.

[0010] Furthermore, a sealing rib is provided on the valve sleeve, and the sealing rib is located in the first cleaning space.

[0011] Furthermore, the valve body assembly also includes a drainage channel, one end of which is connected to the connecting port, and the other end of which is connected to the pulp outlet.

[0012] Furthermore, the slurry outlet nozzle and the valve sleeve are made in one piece.

[0013] Furthermore, the valve sleeve is provided with a spray port connected with the water inlet and the circulation channel.

[0014] The beneficial effects of the present invention are:

[0015] 1. The valve body assembly is provided with a cleaning space. The valve group drive unit drives the valve core to rotate, causing the path of the water flow in the cleaning space to change. Through the changed water flow path, the corners of each cleaning space in the valve body assembly are thoroughly cleaned. Since the valve core is driven to rotate and thus has a certain driving force, the flow rate of the water flowing through the cleaning space is increased, thereby driving the residual slurry and micro-particles in the valve body assembly to flow along the water flow path and eventually be discharged together with the cleaning wastewater. The angle and / or speed and / or direction of the valve core rotation causes the water flow path to change, and the corresponding flow rate changes, diversifying the cleaning state and cleaning speed of different positions in the valve body assembly, thereby thoroughly cleaning every corner of the valve body assembly. Of course, the valve body drive unit can also drive the valve core to move in a targeted manner, so that the water flow path corresponding to the valve core movement strengthens the cleaning of a certain state and position of the valve body assembly, avoiding cleaning dead corners.

[0016] 2. A valve sleeve is provided between the valve core and the valve housing, thereby forming a first cleaning space between the valve core and the valve housing. The valve core rotates and drives water to flow within the first cleaning space formed between the valve core and the valve housing, so that the residual slurry between the valve core and the valve housing is dissolved in water and carried out and discharged outside the valve body assembly. The water flow path in the first cleaning space at least partially overlaps with the slurry flow path during slurrying. Therefore, during the circumferential rotation of the valve core, the valve body assembly switches between the open and closed states multiple times. The water flow continuously changes its path between the state transitions of the valve body assembly. Under the joint drive of the valve core and the water flow, the residual slurry is completely discharged.

[0017] 3. The cleaning space also includes a second cleaning space arranged between the valve sleeve and the valve housing. The second cleaning space is located on the periphery of the first cleaning space and is arranged correspondingly and / or staggered in the radial direction. The second cleaning space can be used as an independent cleaning space. When the flowing water source and the valve group drive unit drive the valve core to rotate, the second cleaning space is indirectly affected by the valve sleeve, the second cleaning space is repeatedly cleaned, and the cleaning wastewater is discharged. Of course, the second cleaning space can be connected to the first cleaning space. At this time, when the valve group drive unit drives the valve core to rotate, water flows in the first cleaning space and the second cleaning space, and the water in the inner first cleaning space and the outer second cleaning space are linked, extending the water flow path, expanding the water flow, and optimizing the deep cleaning effect.

[0018] 4. A first flow channel is provided within the first cleaning space, extending from the gap between the valve core and the valve sleeve. A second flow channel is provided within the second cleaning space, and a connection port is provided on the valve sleeve, connecting the first and second flow channels to form a circulating flow channel. Driven by the valve core, water circulates back and forth within the first and second flow channels for multiple cleaning operations, significantly saving water for automatic cleaning of the valve body assembly. Furthermore, the liquid can be temporarily stored within the cleaning space, allowing for full soaking and disinfection of every corner of the valve body assembly, achieving both deep cleaning and more thorough sterilization. Of course, since the first and second cleaning spaces are connected via the connection port, drying the valve body assembly through a heat drying process is also convenient.

[0019] 5. The circulation flow channel includes a first circulation flow channel in which the valve body assembly opens the slurry outlet, and a second circulation flow channel in which the valve body assembly closes the slurry outlet. In the two states, the paths of the circulation flow channel are different. Water flows through different paths to flush different flow channels and discharge waste water, enriching the cleaning solution. In addition, multi-state cleaning fully reflects the technological sense and intelligence of the food processor that does not require hand washing.

[0020] 6. The valve sleeve is provided with sealing ribs to separate the first cleaning space. More first flow channels are separated by the sealing ribs, making the water flow path more dispersed. At the same time, the sealing ribs also play the role of drainage and diversion, ensuring the reliability of the opening and closing of the valve body assembly while the water flow is quickly discharged. The slurry outlet and the valve sleeve are both made of elastic materials. The one-piece formation not only simplifies the structure of the valve body assembly, reduces the installation gap between multiple accessories, and further optimizes the cleaning path and cleaning effect. At the same time, the installation position of the valve sleeve is unique, the relative position of the valve body and the valve core is accurate, the closed state does not leak slurry, and can make the cleaning space and waste discharge space smoother. Wastewater is not easy to remain in the valve body assembly. The valve sleeve is also provided with a spray port connected to the water inlet and the circulation channel. The spray port increases the water pressure in the water inlet cleaning space and increases the flow rate, so that the water flow flushes the space with greater force, and the water flows smoothly during cleaning.

[0021] 7. The valve body assembly also includes a drainage channel, one end of which is connected to the connecting port and the other end is connected to the slurry outlet. The drainage channel drains the cleaning waste water, and the cleaned waste water quickly passes through the drainage channel and is discharged from the slurry outlet to the residual water box.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1:

[0037] The present invention provides a food processing machine which does not require hand washing. Figures 1 to 3 As shown, it includes a main unit 100 and a processing chamber 200. The main unit is provided with a water tank 102. The processing chamber is provided with a crushing knife 201 driven by a motor. The processing chamber is provided with a slurry outlet 202. The bottom of the processing chamber is also provided with a heating device 103. In this embodiment, the slurry outlet is provided on the bottom wall of the processing chamber. It also includes a valve body assembly 300 and a valve group drive unit 101 connected to the slurry outlet. The valve group drive unit drives the valve body assembly to open or close the slurry outlet 202. The valve body assembly includes a valve shell 301 and a valve core 302 provided in the valve shell. The valve core is provided with a liquid flow hole 309. When the valve body assembly is in an open state to open the slurry outlet, the liquid flow hole 309 is connected to the slurry outlet 202, and otherwise it is closed. The valve body assembly is provided with a cleaning space 400 for water to flow through and automatically clean the valve body assembly. The valve group drive unit drives the valve core to rotate and change the water flow path in the cleaning space.

[0038] The valve body assembly is provided with a cleaning space. The valve group drive unit drives the valve core to rotate, causing the path of water flow in the cleaning space to change. Through the changed water flow path, the corners of each cleaning space in the valve body assembly are thoroughly cleaned. Because the valve core is driven to rotate and thus has a certain driving force, the flow rate of the water flowing through the cleaning space is increased, thereby driving the residual slurry and micro-particles in the valve body assembly 300 to flow along the water flow path and ultimately be discharged together with the cleaning wastewater. The angle and / or speed and / or direction of rotation of the valve core 302 causes the water flow path to change, and the corresponding flow rate to change, thereby diversifying the cleaning state and cleaning speed of different positions in the valve body assembly, thereby thoroughly cleaning every corner of the valve body assembly 300. Of course, the valve body drive unit 101 can also drive the valve core to move in a targeted manner, so that the water flow path corresponding to the valve core movement strengthens the cleaning of a certain state and position of the valve body assembly, avoiding cleaning blind spots.

[0039] A valve sleeve 303 is provided between the valve core 302 and the valve housing 301. Specifically, Figure 2As shown, the valve housing includes a first valve housing and a second valve housing, which together form a space for mounting a valve core and a valve sleeve. The cleaning space includes a first cleaning space 401 disposed between the valve core and the valve sleeve. The valve core rotates, driving water to flow within the first cleaning space 401 formed between the valve core and the valve housing, causing residual slurry between the valve core and the valve housing to dissolve in water and be carried out and discharged outside the valve body assembly. The water flow path in the first cleaning space 401 at least partially overlaps with the slurry flow path during slurrying. As a result, during the circumferential rotation of the valve core, the valve body assembly switches between open and closed states multiple times. The water flow continuously changes its path between the valve body assembly state transitions, and the residual slurry is completely discharged under the combined drive of the valve core and the water flow.

[0040] To enhance the deep cleaning effect of valve body components, such as Figures 4 to 6 As shown, the cleaning space also includes a second cleaning space 402 arranged between the valve sleeve and the valve housing, and the second cleaning space is located on the periphery of the first cleaning space. The second cleaning space can be used as an independent cleaning space. When the flowing water source and the valve group drive unit drive the valve core to rotate, the second cleaning space is indirectly affected by the valve sleeve, the second cleaning space is repeatedly cleaned, and the cleaning wastewater is discharged. Of course, the second cleaning space can be connected to the first cleaning space. At this time, when the valve group drive unit drives the valve core to rotate, the water flows in the first cleaning space and the second cleaning space and causes the water in the inner first cleaning space and the outer second cleaning space to be linked, extending the water flow path, expanding the water flow, and optimizing the deep cleaning effect. In this embodiment, the first cleaning space is connected to the second cleaning space, and the water flows in the two spaces for cleaning.

[0041] The first cleaning space is provided with a first flow channel 403, and the second cleaning space is provided with a second flow channel 404. The valve housing is provided with a connection port 310. The first flow channel is connected to the second flow channel through the connection port 310 to form a circulation flow channel 405. Driven by the valve core, water flows through the first flow channel 403 and the second flow channel 404 for multiple cleanings, thereby greatly saving the water consumption required for automatic cleaning of the valve body assembly. It also allows the liquid to be temporarily stored in the cleaning space, fully soaking and disinfecting every corner of the valve body assembly, achieving a more thorough sterilization while deep cleaning. In this embodiment, the valve housing is provided with a water inlet 304 connected to a water tank. The food processing machine includes a water tank 102 provided on the main unit. The water inlet on the valve housing is connected to the water inlet via a pipeline. The water pump drives the water tank through the water inlet 304 on the valve body assembly to supply water into the processing chamber for pulping or cleaning, and to supply water into the cleaning space within the valve body assembly for self-cleaning of the valve body assembly. The valve body assembly also includes a slurry outlet 305, and the water inlet is connected to the slurry outlet 305 through the circulation channel. When used for self-cleaning of the valve body assembly, water flowing out of the water tank first enters the first flow channel 403 through the water inlet 304, then enters the second flow channel 404 through the connecting port, and circulates to the first flow channel through another connecting port. The first flow channel is connected to the slurry outlet, and the cleaning water is discharged through the slurry outlet. In the circulation channel, at least part of the water circulates to perform multiple cycles of cleaning on at least part of the circulating flow.

[0042] The circulation channel includes a first circulation channel 406 formed when the valve assembly opens the slurry outlet, and a second circulation channel 407 formed when the valve assembly closes the slurry outlet. Water flows through the first and / or second circulation channels for a single clean, multiple cleans, or alternate paths when switching between the two states. In the two states, the circulation channels follow different paths, allowing water to flush different channels through different paths and drain wastewater, enriching the cleaning options. Furthermore, multi-state cleaning fully demonstrates the technological and intelligent nature of the hand-free food processor.

[0043] The valve sleeve is provided with a sealing rib 306. Specifically, the sealing rib is located in the first cleaning space and divides the first cleaning space. More first flow channels are separated by the sealing rib, so that the water flow path is more dispersed. At the same time, the sealing rib also plays the role of drainage and diversion, ensuring the reliability of the opening and closing of the valve body assembly while the water flow is quickly discharged. Of course, if Figure 2As shown, a sealing rib can also be provided on the outside of the valve sleeve to limit the installation of the valve sleeve. The slurry outlet and the valve sleeve are made of an integral body and are made of antibacterial silicone. The integral formation not only simplifies the structure of the valve body assembly, reduces the installation gap between multiple accessories, and further optimizes the cleaning path and cleaning effect, but also the installation position of the valve sleeve is unique, the relative position of the valve body and the valve core is accurate, the slurry does not leak in the closed state, and the cleaning space and the waste discharge space are more fluid, and wastewater is not easy to remain in the valve body assembly. The valve sleeve is also provided with a spray port 308 connected to the water inlet and the circulation channel. The spray port increases the water pressure, spray area and range in the water inlet cleaning space, increases the flow rate, makes the water flow more powerful in flushing the space, and the water flow is smooth during cleaning.

[0044] The valve body assembly also includes a drainage channel 307, one end of which is connected to the connecting port 310 and the other end is connected to the slurry outlet 305. The drainage channel drains the cleaning waste water, and the cleaned waste water quickly passes through the drainage channel and is discharged from the slurry outlet to the residual water box.

[0045] In order to further improve the cleaning effect, in this embodiment, the valve body assembly is optimized. The valve body assembly includes a closed state in which the valve group drive unit drives the valve core to close the slurry outlet, and an open state in which the valve group drive unit 101 drives the valve core to open the slurry outlet. When the valve body assembly is in the closed state, a micro-pressure space 408 is formed in the valve body in which the liquid flow is buffered in the valve body assembly. At this time, the water flow can be soaked and cleaned in the micro-pressure space. In addition, combined with the food processor heating device, high-temperature soaking and pasteurization of the inside of the valve body assembly can also be achieved, and the valve body assembly can be sterilized more thoroughly.

[0046] The valve body assembly includes a water inlet 304 and a pulp outlet 305. When the valve body assembly is in the closed state, water flows from the water inlet into the micro-pressure space 408 and is discharged from the pulp outlet. The flow rate discharged from the pulp outlet is less than the flow rate entering from the water inlet. The water pressure in the micro-pressure space increases, and the fluidity is enhanced, so that the inner wall of the channel in the valve body assembly is cleaned more thoroughly, and the water flow is more focused on flushing specific locations and every corner of the valve body assembly when it flows through. The water inlet is connected to the water tank, and water is supplied through the water tank, further simplifying the user's preparation actions before pulping. It only needs to put the materials into the food processor, and there is no need to manually add water.

[0047] In this embodiment, the valve sleeve is fixed relative to the valve housing 301, the valve sleeve 303 is arranged between the valve core and the valve housing, and the valve core is provided with a liquid flow hole 309. Figure 4 As shown, when the valve group driving part drives the valve core to rotate to the first position, the liquid flow hole is connected with the slurry outlet and the slurry outlet nozzle respectively, so that the valve body assembly is in the open state, as shown in FIG. Figure 5As shown, when the valve group drive unit drives the valve core to rotate to the second position, the liquid flow hole 309 is connected to the water inlet, and the valve body assembly is in the closed state. When the valve core is in the second position, the drainage channel is closed by the valve core 302, and the micro-pressure space 408 is formed inside the valve body assembly. At this time, the micro-pressure space is separated from the processing cavity. The water flow entering the micro-pressure space from the water inlet cleans the interior of the valve body assembly. Part of the water flow is discharged from the slurry outlet through the second circulation channel 407, and at least part of the water flow accumulates in the micro-pressure space 408. New water flow enters from the water inlet and replaces the water flow accumulated in the micro-pressure space, so that the originally accumulated water flow is discharged from the slurry outlet. The new water flow continuously replaces the water flow in the original micro-pressure space 408, and the residual slurry is gradually discharged with the cleaning water flow until the interior of the valve body assembly is thoroughly cleaned. When the valve group drive unit drives the valve core to the first position, the processing chamber is connected to the slurry outlet nozzle. At this time, the valve core rotates and allows most of the water to be discharged from the slurry outlet nozzle through the channel in the valve body assembly. A small amount of water flows into the gap between the valve core and the valve sleeve as the valve core rotates, flushing the slurry in the gap, thereby ensuring that there is no cleaning dead corner inside the valve body assembly.

[0048] like Figure 6 As shown, when the valve group drive unit drives the valve core to rotate to the third position, the valve body assembly is still in a closed state. At this time, the liquid flow hole on the valve core is connected to the drainage channel, and waste is discharged in the closed state. The cleaning waste water used to clean the cleaning space of the valve body assembly is discharged through the drainage channel.

[0049] A first flow channel 403 is provided between the valve core and the valve sleeve, a second flow channel 404 is provided between the valve sleeve and the valve housing, and a connecting port 310 is provided on the valve sleeve. The first flow channel is connected with the second flow channel through the connecting port to form a circulation flow channel. When the valve body assembly is in a closed state and the valve core is in the second position, the circulation flow channel forms the micro-pressure space, thereby fully immersing and disinfecting the interior of the valve body assembly through the micro-pressure space, and performing more thorough sterilization while deep cleaning.

[0050] The water inlet includes a first water inlet 311 provided on the valve housing, and a second water inlet 312 provided on the valve sleeve. The first water inlet is connected to the second water inlet so that water flowing out of the water tank can smoothly enter the space within the valve sleeve through the first water inlet and the second water inlet, or enter the space within the valve sleeve and between the valve sleeve and the valve housing, thereby deeply washing the valve body assembly. The first water inlet and / or the second water inlet are porous spray ports. In this embodiment, the second water inlet is a porous spray port 308, which increases the water pressure entering the micro-pressure space and increases the flow rate, so that the water flow flushes the space with greater force, and the water flow is smooth during cleaning.

[0051] The connecting ports are provided with one, two or more. According to the path of the circulation channel and the requirements of the cleaning functionality, the number, diameter and position of the connecting ports can be optimized and designed, taking into account the reliability of the valve body assembly opening and closing the slurry outlet and the deep cleaning effect inside the valve body assembly. In this embodiment, there are three connecting ports, and the connecting ports and the second water inlet are distributed along the circumference of the valve sleeve to ensure the sealing reliability when the slurry outlet is closed during the rotation of the valve core. At the same time, the circulation channel can fully circulate and automatically clean the internal space of the valve body assembly under the drive of the valve core. Specifically, Figures 4 to 6 As shown, starting from the water inlet, in the counterclockwise direction, the connection ports include the first connection port 313, the second connection port 314 and the third connection port 315. The second connection port is connected to the first flow channel 403 and the drainage channel 307 respectively. The water flow of the first flow channel is discharged to the drainage channel through the second connection port and finally discharged from the pulp outlet. Figure 5 As shown, in this embodiment, the drainage channel includes a guide section 316 and a discharge section 317. The guide section is connected to the second connecting port to divert the water flow of the first flow channel. The downstream of the guide section is connected to the upstream of the discharge section to change the direction of the water flow and guide the cleaning water flow toward the pulp outlet. The downstream of the discharge section is connected to the pulp outlet. The discharge section forms an angle α with the horizontal plane, α≥5°, preferably 15°≤α≤45°, and the total α in this embodiment is 30°. The water flow has a certain flow rate, and when discharged through the discharge section, it rotates and flows in the pulp outlet pipe, thereby strongly flushing the inner wall of the pulp outlet pipe, optimizing the cleaning effect and saving cleaning water.

[0052] It is understood that a connecting pipeline is provided between the water inlet and the water tank, and the food processor includes a heating device. To shorten cleaning time and improve cleaning efficiency, the connecting pipeline is at least partially positioned adjacent to the heating device to heat water flowing through the connecting pipeline. The heating device preheats the water entering the valve body assembly, thereby achieving high-temperature cleaning, high-temperature immersion, and pasteurization of the micro-pressure space, fully ensuring the hygiene and safety of the valve body assembly. Alternatively, a connecting pipeline is provided between the water inlet and the water tank, and a heating element is provided on the connecting pipeline to heat the water flowing through the connecting pipeline. The heating element may be an electric heating film or a heating tube.

[0053] It can be understood that since the first cleaning space and the second cleaning space are connected through the connecting port, the valve body assembly can also be subjected to a heat drying treatment by a heating device.

[0054] It can be understood that a water inlet is provided on the valve housing, and the water inlet is connected to a water source.

[0055] Example 2:

[0056] In this embodiment, Figure 7As shown, the valve body assembly includes a valve housing, a valve core arranged in the valve housing, and a valve sleeve 303 sleeved on the outside of the valve core 302. The valve core is provided with a liquid flow hole 309. When the valve body assembly is in a closed state, the valve core blocks the slurry outlet 202. At least one connecting port 310 on the valve sleeve is connected to the liquid flow hole, and the connecting port connected to the liquid flow hole is larger than other connecting ports. The water flow entering from the water inlet can be fully soaked in the liquid flow hole and the cleaning space and gradually discharged. Of course, in order to accelerate the discharge of wastewater, the valve group drive unit can also drive the valve core to rotate to an open state, thereby quickly discharging waste.

[0057] It can be understood that the valve sleeve is provided with a hollow portion. When the valve body assembly is in a closed state, the liquid flow hole on the valve core and the hollow portion on the valve sleeve are always in a connected state, which intensifies the circulation and cleaning force of the water flow in the circulation channel, thereby making the space between the valve sleeve and the valve core clean more thoroughly.

[0058] Example 3:

[0059] In this embodiment, no connection port is provided on the valve sleeve, a valve sleeve is provided between the valve core and the valve housing, and a liquid flow hole is provided on the valve core. The cleaning space is the first cleaning space provided between the valve core and the valve sleeve. The valve group drive unit drives the valve core to rotate 360° forward and reverse, thereby driving the water flow entering from the water inlet to rotate back and forth in the first cleaning space. The valve body assembly switches back and forth between the open state and the closed state, thereby changing the water flow path, so that the residual slurry in the first cleaning space between the valve core and the valve sleeve is carried away by the water flow. In this solution, no liquid flows through the space between the valve sleeve and the valve housing, and it is isolated from the first cleaning space and does not need to be cleaned. This setting achieves the highest reliability in the closed state while realizing automatic cleaning of the valve body assembly. It can achieve precise control of the open and closed states between the water inlet, the slurry outlet, and the slurry outlet nozzle by controlling the rotation angle of the valve core, realizing self-cleaning of the valve body while greatly improving the reliability of the entire machine.

It should be noted that the combination of multiple technical solutions in any one embodiment, as well as the combination of the technical solution of any one embodiment with the technical solutions in one or more other embodiments, are within the scope of protection of the present invention. Although the present invention has been described in detail above using general descriptions and specific embodiments, it is obvious to those skilled in the art that modifications or improvements can be made based on the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention are within the scope of protection claimed by the present invention.
