Technical Field

[0002] The invention belongs to the technical field of food equipment, and in particular relates to an integrated intelligent household tofu machine and a working method thereof. Background Art

[0003] There are three main methods for making tofu at present, one is large-scale production line production, one is commercial medium-sized equipment, and one is manual production using molds. Medium-sized and large-scale equipment usually has a crushing module, a pulping module and a pressing module separately set up. The crushing module includes a crushing cup, the pulping module includes a pulping cup, and the pressing module includes a pressing box. The crushing of the material is completed in the crushing cup to make a slurry, and then the slurry is discharged to the pulping cup, and the slurry is cooked and matured in the pulping cup. Then the cooked soybean milk is filtered and discharged to the pressing box, and the brine and pressing are completed in the pressing box. However, the independent setting of each module makes the entire machine bulky, and there are also many cleaning parts, which is cumbersome to use. The manual production process using molds is too cumbersome and requires high production experience.

[0004] For this reason, various household tofu machines have appeared on the market. For example, Chinese invention patent application number 201110445428.3 discloses a household tofu machine, including a base, a soybean milk machine, a tofu forming box and a control circuit. Between the tofu forming box and the soybean milk machine cup body, a diversion mixing device for mixing soybean milk stock liquid with a coagulant is provided. The liquid outlet of the coagulant in the coagulant injection device is placed in the mixing diversion mixing device. The process steps of beating, filtering, slurrying and tofu molding of making tofu are automatically completed on one tofu machine, and the mixing uniformity of the soybean milk stock liquid and the coagulant is fully improved in the slurrying step, so that the quality and taste of the molded tofu are better.

[0005] For another example, a Chinese invention patent with application number 201410500532.1 discloses a household tofu machine, including a braising box, a slurry cooking cup, and a pressing module. The pressing module includes a pressing plate and a driving mechanism for driving the pressing plate to move. The braising box is connected to the slurry cooking cup, and the braising agent in the braising box is discharged into the slurry cooking cup to realize braising. The pressing module is located above the slurry cooking cup, and a drainage groove / hole for filtering out yellow slurry water is provided on the pressing plate. The driving mechanism drives the pressing plate to move along the inner wall of the slurry cooking cup to squeeze out the yellow slurry water through the drainage groove / hole to realize tofu pressing. In this way, slurry cooking, braising and tofu pressing are all completed in the same cup body.

[0006] However, the above scheme has at least the following shortcomings: 1. The filter is set inside the container and is not easy to clean; 2. The tofu produced is of a single type; 3. Halogen is added by air pump pressurization, which requires complex equipment, high cost, and difficult to control the amount; 4. The upward drainage method will cause the yellow water to soak the tofu for a long time, affecting the quality of the tofu. Summary of the invention

[0026] Embodiment 1 See also Figure 1 The present application provides a braising mechanism for a household tofu maker, comprising: a braising bottle 402, a docking seat 403 and a first driving device 401, and a push-type braising switch arranged on the braising bottle; wherein the first driving device can be an electric push rod.

[0027] See also Figure 2 and Figure 3 , the halogen-making bottle is provided with a powder outlet, the top of the docking seat is open, and the docking seat forms a first groove, a second groove and a third groove which are connected in sequence from the first end to the second end, a powder outlet channel 408 is provided at the bottom of the first groove, the halogen-making bottle and the first driving device 401 are respectively installed in the first groove and the third groove, and the pressing part of the halogen-making switch and the output end of the first driving device extend out of the first groove and the third groove respectively and are located in the second groove, a card groove is provided on the pressing part, and the output end abuts against the card groove; When the output end of the first driving device moves along a first direction, the first driving device drives the pressing part to move along the first direction to open the powder outlet, so that the halogen in the halogen bottle can enter the powder outlet channel through the powder outlet; when the first driving device moves along a second direction, the first driving device drives the pressing part to reset and block the powder outlet; wherein the first direction is opposite to the second direction.

[0028] When the pressing portion is manually pressed toward the first direction, the output end is disengaged from the card slot, so that the halogen ignition bottle and the halogen ignition switch can be taken out from the docking seat.

[0029] In some embodiments, the bottle mouth of the halogen bottle is provided with a bottle cap 405, and the bottle cap 405 is provided with a accommodating cavity for installing the halogen switch, and one side of the bottle cap is open; the push-type halogen switch includes a reset member 406 and a slider 407, one end of the reset member 406 is fixed on the bottle cap 405 (for example, on the inner wall of the bottle cap), and the other end of the reset member 406 (preferably a spring) is fixed to the slider 407, the telescopic direction of the reset member 406 is parallel to the first direction and the second direction, and the second end of the slider extends out of the accommodating cavity to form the pressing portion; accordingly, the powder outlet includes a first opening provided on the first side of the bottle cap, and a second opening provided on the second side of the bottle cap and corresponding to the powder outlet channel, and the first opening and the second opening are staggered; a powder taking channel 409 is provided on the slider, and the position of the powder taking channel 409 is changed by changing the position of the slider 407, so as to respectively correspond to the first opening and the second opening to realize powder taking and feeding.

[0030] It should be noted that the bottle body 404 of the braising bottle can be made into different sizes. Similarly, the powder taking channel 409 of the slider can also be set to different sizes. The braising bottle and the braising switch with different powder taking amounts can be replaced according to the user's demand for making tofu.

[0031] Specifically, when the halogen ignition switch is not affected by external force, the first opening corresponds to the powder taking channel, and the halogen enters the powder taking channel through the first opening to achieve quantitative powder taking; when the slider moves toward the first direction under the action of external force, the powder taking channel corresponds to the powder outlet channel, and at the same time the slider blocks the first opening, and the halogen in the powder taking channel enters the powder outlet channel to achieve feeding. When the external force is removed, the reset member drives the slider to reset, and the powder taking channel takes powder again to prepare for the next production.

[0032] When disassembling the brining bottle, the operator presses the pressing part to separate the pressing part from the output end of the first drive device and then lifts up the brining bottle. Correspondingly, when installing the brining bottle, the operator presses the pressing part, puts the brining bottle into the first groove and then lets go. The pressing part is reset under the action of the reset member, so that the slot of the pressing part is locked correspondingly with the output end of the first drive device, thereby restricting the pressing part within the first groove.

[0033] In some embodiments, the powder outlet channel 408 is divided into a vertical section and an inclined section from its first end to its second end, the vertical section is parallel to the height direction of the tofu machine, and the inclined section is arranged along the second direction so that a bending structure is formed at the connection between the vertical section and the inclined section; when feeding, the brine first falls quickly through the vertical section, and then enters the pressing mechanism through the inclined section, and its bending structure can effectively prevent the soy milk from flowing back into the bottle cap during the flushing process.

[0034] In some embodiments, the width of the second groove is smaller than the width of the first groove and the third groove, so as to confine the halogen bottle and the first driving device within the first groove and the third groove respectively.

[0035] In some embodiments, the width of the pressing portion (slider) is close to the width of the second groove. For example, when the pressing portion is installed in the second groove, two sides of the pressing portion respectively rest against the inner wall of the second groove to prevent the halogen bottle from shifting during the pressing process.

[0036] In some embodiments, the height of the pressing portion is higher than the height of the second groove, so that the user can quickly find the force point when manually pressing.

[0037] In some embodiments, a scale line is provided on the top of the pressing portion to facilitate the user to grasp the pressing force according to the scale line to prevent mis-injection caused by excessive pressing.

[0038] In other embodiments, the length of the pressing portion is smaller than the minimum distance between the powder taking channel and the powder discharging channel. That is to say, during the pressing process, when the end of the pressing portion is flush with the brining bottle or the bottle cap, the user's fingers are blocked and cannot continue to press inward. At this time, the powder taking channel has not yet corresponded to the powder discharging channel. When feeding, the output end of the first drive device is used to drive the pressing portion to continue to move inward to achieve feeding. This can prevent the user from accidentally feeding the brining agent during the process of replacing the brining bottle.

[0039] In some specific embodiments, when the output end of the electric push rod moves to a maximum in the first direction, and / or when the reset member is compressed to a maximum, the powder outlet channel and the powder collection channel correspond to each other.

[0040] In some embodiments, the halogenating bottle is provided with a powder filling port for convenient adding materials, so that the halogenating bottle can be reused to reduce costs. In some specific embodiments, the powder filling port can be provided at the bottom of the halogenating bottle, or the bottle cap is detachably connected to the halogenating bottle, wherein the bottle cap is provided with an internal thread, and the bottle mouth of the halogenating bottle is provided with an external thread matching the internal thread, and the user can remove the bottle cap and add materials through the bottle mouth.

[0041] In some embodiments, the inner diameter of the first groove gradually decreases from the top to the bottom of the groove, so that the open end of the first groove forms an installation slope opening upward, so as to reduce the difficulty of installing the brining bottle.

[0042] Most of the prior art uses liquid halogens, but liquid halogens are prone to precipitation and need to be stirred before each use. In addition, liquid halogens are easy to deteriorate, which leads to high requirements on the sealing performance of the halogen-adding mechanism. For this reason, the prior art usually requires reducing the need for disassembly and assembly, and only disassembling and cleaning some parts (such as the air inlet pipe). However, how to ensure the quality of the halogen inside the halogen-adding container (such as the halogen-adding bottle) and how to clean the halogen-adding container are more troublesome. The present application proposes a halogen-adding mechanism that can be used for powdered halogen. On the one hand, the halogen-adding bottle in the present solution is fed by a one-touch pressing method, and there is no need to set up an additional air pump or other structure to stir the halogen. The structure is simple and easy to use. Specifically, the halogen-adding bottle in the present application is Through holes at different positions are arranged on the bottle cap, which cooperate with the powder taking channels on the slider to realize quantitative powder taking without manual intervention. Furthermore, according to different tofu production quantities, the brine switches with powder taking channels of different sizes can be replaced, and the user can make different types of tofu (such as rennet tofu, gypsum tofu, brine tofu, etc.) by replacing the brine bottles filled with different brine agents; on the other hand, the user can install and disassemble the brine bottle by pressing the push-type brine switch. That is to say, through the structural characteristics of the brine switch and the first drive device itself, in conjunction with the docking seat structure with multiple limit grooves, the brine mechanism can be quickly disassembled and assembled, and there is no need to set up additional fixed structures, which is convenient for users to take and place the brine bottle for operations such as adding materials or cleaning.

[0050] The upper pressing chamber 502 and the lower pressing chamber 503 are provided with a first fastening member and a second fastening member respectively; when the first fastening member and the second fastening member are fastened, the upper pressing chamber 502 and the lower pressing chamber 503 are locked to form the pressing chamber; when the first fastening member and the second fastening member are opened, the upper pressing chamber 502 can be removed from the lower pressing chamber 503. The upper pressing chamber 502 and the lower pressing chamber 503 are designed to be split. After the pressing is completed, the upper pressing chamber 502 can be removed, so as to facilitate the removal of the tofu and the cleaning of the upper pressing chamber 502 and the water filter component 512 provided in the upper pressing chamber 502.

[0051] In some specific embodiments, the bottom of the pressing upper chamber 502 extends inward to form a mounting table that is perpendicular to the side wall of the pressing upper chamber 502, and the water filtering component 512 is placed on the mounting table, so that the water filtering component 512 can be easily removed for cleaning, and the width of the mounting table is much smaller than the width of the water filtering component 512, thereby avoiding obstruction of the water filtering holes on the water filtering component 512.

[0052] In some embodiments, a sliding member 504 is provided on the tofu machine, and the pressing bin is slidably provided on the tofu machine through the sliding member 504; specifically, a slide rail can be provided on the tofu machine, and a pulley is provided at the bottom of the pressing bin, that is, the pressing bin adopts a "pull-out" design to facilitate taking tofu.

[0054] In some embodiments, a drain outlet 519 is provided at the bottom of the pressing bin.

[0055] During specific use, the pressing upper bin is installed on the pressing lower bin, and the two are locked by the first buckle and the second buckle, and the water retaining component is pressed against the bottom of the water filtering component for sealing by the third driving device, soy milk and brine are added into the pressing upper bin, and after the soy milk is solidified, the water retaining component is separated from the water filtering component by the third driving device to expose the water filtering hole, and the pressing plate is driven by the second driving device to press the tofu. During pressing, the waste water (yellow water) generated in the process of pressing the tofu can flow to the upper surface of the water retaining component (i.e., the upper surface of the first water retaining plate) through the filter holes on the water filtering component, and flow along the first water retaining plate to the second water retaining plate arranged around the first water retaining plate for diversion, and the diverted waste water flows into the water storage space along the second water retaining plate for temporary storage. After pressing is completed, the waste water in the water storage space is discharged through the drain port, and finally the pressing bin is pulled out of the tofu machine, and the buckle is opened to remove the pressing upper bin, so as to facilitate the removal of the tofu therein.

[0056] In the prior art (201110353816.9), the driving mechanism for controlling the lifting of the sealing plate is arranged outside the pulp dispensing container, and is connected to the driving mechanism through the pulp dispensing container via a transmission component (switch plate). On the one hand, the external driving device needs to occupy more space, which is not suitable for small-sized household tofu machines, and the appearance is not beautiful. On the other hand, this installation method requires an opening to be set on the container, which makes it difficult to ensure its airtightness. The driving device in this application adopts a built-in design. Specifically, on the one hand, a closed space for installing the third driving device is formed between the inner wall of the lower bin and the water retaining component, and the waterproof performance of the third driving device is effectively guaranteed. The built-in design can greatly reduce the noise of the household tofu machine when it is working. On the other hand, the lower bin and the inner wall of the lower bin are pressed to form a water storage space, and there is no need to set up a separate water storage mechanism (such as a wastewater box), and the water retaining component can effectively divert the wastewater, thereby meeting the rapid drainage requirements of small-volume household tofu machines.

[0057] In summary, the present application provides a pressing mechanism based on a built-in driving device and rapid drainage in all directions, which can ensure the airtightness of the tofu machine while rapidly draining water, thus meeting the needs of small household tofu machines.

By setting the cut-off turntable 522 to have a first area 5221 and a second area 5222 with different heights, even if a small amount of leakage occurs accidentally when the wastewater enters the drainage channel 5231 through the water permeable hole 5224, its "step-type" design can limit the leaked wastewater to the second mounting groove 5233 and gradually enter the drainage channel 5231 for discharge. In addition, when the cut-off turntable 522 rotates, the second area 5222 of the cut-off turntable 522 can scrape away the wastewater in the second mounting groove 5233 to a certain extent.

[0066] A docking hole 5235 is provided at the bottom of the docking column 5223 , and the output shaft of the third driving device 526 can be inserted into the docking hole 5235 , thereby driving the cut-off rotating disk 522 to rotate.

[0068] In some embodiments, the pressing mechanism includes a mounting shell, one of the side walls of the mounting shell is open, and at least two slide rails with different heights are respectively arranged in the mounting shell along the direction from the opening of the mounting shell to the opposite side thereof, and the wastewater box 6 and the pressing box are respectively slidably arranged on the slide rails, and handles 521 are respectively arranged on the pressing bin and the wastewater box 6. By pulling the handle 521, the pressing box and the wastewater box 6 slide on the slide rails, which facilitates the removal of the tofu from the pressing mechanism after the pressing is completed.

[0069] In some embodiments, a pressure sensor is provided between the pressing plate 510 and the output end of the second driving device 501, and the pressing pressure is collected in real time by the pressure sensor, so that the pressing process is carried out at a reasonable speed, thereby improving the taste of the tofu.

[0070] During specific use, the water filter holes of the filter component are first blocked, soy milk and brine are added into the upper pressing bin, and after the soy milk solidifies, the water permeable holes on the cut-off turntable and the water filter holes on the water filter component are staggered by the third driving device, and the pressing plate is driven by the second driving device to press the tofu. During the pressing process, the waste water (yellow water) generated during the tofu pressing process can enter the waste water box through the water filter holes, the drainage channel and the perforation in sequence. After the pressing is completed, the pressing bin is pulled out to take out the tofu.

[0071] In summary, the present application provides a drawer-type pressing mechanism based on a built-in driving device for a miniaturized household tofu maker.

[0073] Furthermore, the concave-convex structural design of the water retaining component forms a stepped waterproof structure. At the same time, with the cooperation of sealing components such as sealing strips, the water discharge performance between the water retaining component and the filter component can be effectively guaranteed.

[0074] Embodiment 4 See also Figure 19-21The present application also provides an integrated intelligent household tofu maker, including a water storage module 1, a grinding module 2, a filtering module 3, a brine-making mechanism 4 and a pressing mechanism 5; a heating component 8 is provided in the grinding module 2, the water storage module 1 is connected with the grinding module 2 through a pipeline, the outlet end of the grinding module 2 corresponds to the inlet end of the filtering module 3, the filtering module 3 and the brine-making mechanism 4 are connected with the pressing mechanism 5 through a Y-shaped joint, wherein the outlet end of the filtering module 3 is connected with the first inlet of the Y-shaped joint, the powder outlet channel of the brine-making mechanism 4 is connected with the second inlet of the Y-shaped joint, and the feed port of the pressing mechanism 5 is connected with the discharge port of the Y-shaped joint.

[0075] Specifically, the Y-shaped joint includes a first feed section arranged along a first angle, a second feed section arranged along a second angle, and a discharge section arranged along a third angle, and the first inlet, the second inlet and the discharge port are respectively arranged at the ends of the first feed section, the second feed section and the discharge section.

[0076] In some embodiments, the inner diameter of the discharge section gradually decreases from the feed end to the discharge end, and / or the inner diameter of the first feed section is larger than the inner diameter of the discharge section, so that the water pressure of the soy milk gradually increases when entering the pressing bin, thereby fully stirring the soy milk and brine in the pressing bin.

[0077] In some embodiments, the powder outlet channel is divided into a vertical section and an inclined section from its first end to its second end, the vertical section is parallel to the height direction of the tofu machine, and the inclined section is coaxial with the pipe section where the second inlet is located. When feeding, the brine first falls quickly through the vertical section, and then enters the pressing mechanism 5 through the inclined section. Its bending structure can effectively prevent the soy milk from flowing back into the bottle cap during the flushing process.

[0078] In other embodiments, the powder outlet channel is arranged along the vertical direction; correspondingly, the second feed section is arranged in the extension direction of the powder outlet channel, that is, the powder outlet channel, the second feed section and the outlet section are connected to form a straight tube, and the halogen can fall vertically from the feeding channel into the pressing bin to prevent the halogen from accumulating in the pipeline.

[0079] In some embodiments, referring to Example 1, the halogen generation mechanism 4 includes a halogen generation bottle 402, a docking seat and a first driving device 401, and a push-type halogen generation switch arranged on the halogen generation bottle 402; the halogen generation bottle 402 is provided with a powder outlet, the top of the docking seat is open, and the docking seat forms a first groove, a second groove and a third groove that are connected in sequence from the first end to the second end, the powder outlet channel is arranged at the bottom of the first groove, the halogen generation bottle 402 and the first driving device 401 are respectively installed in the first groove and the third groove, and the pressing portion of the halogen generation switch and the output end of the first driving device 401 respectively extend out of the first groove and the third groove and are located in the second groove, and a card groove is arranged on the pressing portion, and the output end is against the card groove.

[0080] In some embodiments, the structure of the pressing mechanism 5 can refer to the pressing mechanism 5 in the second embodiment; in other embodiments, the pressing mechanism 5 can also adopt the structure in the third embodiment.

[0081] In some embodiments, the water storage module 1 is a clean water tank for storing clean water, the refining module 2 can adopt the refining part structure in the prior art (such as a wall breaking machine), and the filtering part can be a filter cup with filter holes set at the bottom. Of course, the tofu machine also includes an electrical compartment 7, and the electrical compartment 7 specifically includes a main control board, a driving device and a power supply; water pumps are provided on the pipeline between the water storage module 1 and the refining module 2, and between the refining module 2 and the filtering module 3.

[0082] Illustratively, when the tofu machine is in use, after the machine is started, the water pump between the clean water tank and the grinding water channel will quantitatively add clean water from the water tank to the grinding part, first the soybeans will be cooked by the heating plate, and then the soybeans will be converted into soy milk by intermittent alternating heating and grinding, and then the braising mechanism will determine the mass of the braising agent to be added according to the set tofu type, tofu quality and other data, and use the first driving device (such as an electric push rod) to quantitatively add the braising agent to the pressing part, wait for the soy milk to be completed, and the soy milk will pass through the filtering device while hot to filter out the bean dregs before entering the pressing part. The brine is fully dissolved by impacting the soy milk. The soy milk is poured in itself is a stirring process, which can fully dissolve the brine. Specifically, the powdered coagulant falls into the water pipe, and the soy milk flows through and then rushes into the pressing container. This process takes about 40 seconds, which can fully dissolve the coagulant. The tofu will gradually cool and solidify into tofu pudding in the pressing mechanism. After sufficient solidification, the screw motor will drive the pressing plate and other mechanisms to press the tofu into shape, and discharge the generated yellow water and other waste liquids.

[0083] After taking out the tofu, the remaining clean water in the clean water tank enters the grinding part to be heated, and then enters each module in turn to achieve self-cleaning.

[0084] In some embodiments, a water pump is provided in the waste water box or the water storage space, and the negative pressure of the water pump can fully pump out the waste water in the upper pressing bin to prevent water accumulation in the upper pressing bin.

[0085] Compared with traditional tofu production machines, the tofu brine container and pressing mechanism in the intelligent household tofu machine of this embodiment adopt an integrated structure, that is, the brine container and the tofu pressing and molding container are integrated into one container, which greatly reduces the volume of the machine. The present invention simultaneously performs the grinding step and the boiling step in tofu making, thereby reducing the production time. The use of dry bean grinding technology eliminates the time for soaking soybeans. Compared with the 3-hour production time required for traditional commercial tofu machines, the tofu production time is reduced to about 50 minutes. At the same time, traditional tofu machines need to dissolve the brine agent before adding it, which is not convenient for storage. The present invention can use powdered brine agents to make tofu, and different types of tofu (gypsum tofu, brine tofu, rennet tofu, etc.) can be made by replacing the brine agent.

[0086] Embodiment 5 Based on the household tofu machine in the fourth embodiment, the present application also provides a working method of an integrated intelligent household tofu machine, see Fig. 22 , including the following steps: S201: The user adds clean water to the water storage module, adds soybeans to the pulping module, and starts the tofu machine; S202: the water storage module pumps a certain amount of clean water into the refining module, and the refining module performs refining and heating alternately to convert the raw materials into soy milk; S203 quantitatively adding halogenating agent through the halogenating mechanism; S204: extracting the soy milk into the filtering module for filtering, and then allowing the filtered soy milk to enter the pressing mechanism; S205 After the soy milk and the brining agent are mixed and cooled in the pressing mechanism to form tofu pudding, the pressing mechanism presses the tofu pudding to form tofu.

[0087] In some embodiments, S205 also includes: when the tofu pudding is pressed, the liquid generated during the pressing process is discharged simultaneously.
