Description

Technical Field

[0001] The invention relates to small kitchen appliances, in particular to a food processor. Background Art

[0002] The cup body of a food processing machine with a heating function in the prior art, such as the heating cup body of a soymilk maker, comprises a stainless steel inner cup, a heat-conducting aluminum plate and a heating tube. During operation, the heating tube is required to heat the material in the cup body to a certain temperature for pulping, thereby achieving a better crushing effect.

[0003] In this process, the water added to the cup body is generally room temperature water. Therefore, during the processing and production process, it takes a long heating time to heat the room temperature water in the cup body to the required temperature, which increases the pulping cycle and brings a bad experience to users.

[0004] In order to solve the above problems, there is also a food processing machine, which is equipped with a corresponding instant heating device. The water entering the cup body is preheated by the instant heating device before being added to the cup body, which solves the heating time to a certain extent. However, in the process of food processing, especially when making soy milk, a certain amount of boiling is required, so a corresponding heating device is also provided on the cup body. In this way, the food processing machine needs to be equipped with multiple heating devices and control two heating systems, which reduces the efficiency of the heating device, makes its work single, leads to a lot of cost increase, and the structural system is relatively complicated.

[0005] At the same time, the above-mentioned existing technologies also have the problem that the prepared soy milk cannot be drunk in time. Since the soy milk needs to be heated and boiled during the preparation process, the prepared soy milk is a high-temperature drink, which users cannot drink in time. Summary of the Invention

[0006] The purpose of the present invention is to provide a food processing machine that can solve the problems of processing time efficiency, cost, and suitability for drinking.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a food processing machine, including a cup body and a crushing device arranged in the cup body, the cup body including a cup body base forming a liquid holding cavity and a heating tube for heating the cavity wall of the cup body base, wherein a water pipe is provided on the cavity wall of the cup body base along the setting trajectory of the heating tube, the heating tube is thermally connected to the water pipe to form a temperature control component, and the temperature control component controls and adjusts the temperature of the liquid in the cup body base.

[0008] Furthermore, the water pipe includes a water outlet, and the water outlet is connected to the interior of the cup body.

[0009] Furthermore, the heating pipe and the water pipe are integrally formed.

[0010] Furthermore, the temperature control component is integrally formed with the cavity wall of the cup body base, and the heating pipe and the water pipe are at least partially hidden in the cavity wall of the cup body base.

[0011] Furthermore, the temperature control assembly includes a plurality of heating tubes and / or a plurality of water tubes, and the heating tubes and the water tubes are spaced apart;

[0012] Alternatively, the heating tube is arranged in multiple circles on the cavity wall of the cup body base, and / or the water tube is arranged in multiple circles on the cavity wall of the cup body base, and a single circle of heating tube is arranged at intervals from a single circle of water tube.

[0013] Furthermore, the temperature control component is arranged on the outer cavity wall of the cup body base, and a water pipe is provided on the upper part of the heating tube.

[0014] Furthermore, the wall thickness of the heating tube is not greater than 1 mm, and the outer diameter of the water tube is not greater than 8 mm.

[0015] Furthermore, the temperature control assembly is provided with a temperature protection device mounting portion, and the temperature protection device mounting portion is provided with a heating fuse and a temperature sensor.

[0016] Furthermore, the heating tube is provided with a connector for connecting to a power supply, the connector includes an insulating magnetic bead and a connecting needle, and the insulating magnetic bead extends out of the temperature control component by a distance L1, 3mm≤L1≤10mm.

[0017] Furthermore, the water pipe is provided with an external connection port for water circulation, the horizontal distance between the external connection port and the insulating magnetic bead is L2, 10mm≤L2≤20mm, and the horizontal distance between the external connection port and the connecting needle is L3, 8mm≤L3≤15mm.

[0018] After adopting the above technical solution, a water pipe is provided on the cavity wall of the cup body base along the setting track of the heating pipe. The heating pipe is thermally connected to the water pipe to form a temperature control component. Since the water pipe is provided along the setting track of the heating pipe and the two are thermally connected, the heating pipe will inevitably heat the water pipe during the heating process. Since both are provided on the cavity wall of the cup body base, this will inevitably form a temperature control component to control and adjust the temperature of the cup body. The reason is that the heating pipe and the water pipe are controlled as two independent channels, that is, they can work simultaneously or independently. Therefore, the cup body can be heated by the heating pipe, and the cup body can also be cooled by the water in the water pipe. The temperature control component is formed on the cup body base, and the reuse function of the heating pipe is increased, while the cooling function of the water pipe is utilized.

[0019] In other words, the temperature control component can actually have multiple working combination modes. The heating tube can heat the cup body and water pipe separately, or it can heat the cup body and water pipe at the same time. This looks the same on the surface, but in fact it is determined by whether there is water in the water channel and the cup body.

[0020] In this way, water can be fed into the cup through the water pipe. During the water intake process, it is heated by the heating pipe. At the same time, the heating pipe heats the water that has already entered the cup. This is equivalent to reusing the heating pipe, improving the utilization efficiency of the heating pipe, shortening the heating time, and reducing the overall time it takes for the food processor to prepare food. After the food is prepared, the heating pipe stops heating, and the water in the water pipe can cool the food in the cup. Of course, at this time, the water in the water pipe can be stationary or flowing. If it is flowing, it is only necessary to set a corresponding selection valve at the water outlet of the water pipe so that the water out of the water pipe does not enter the cup.

[0021] In addition, this structure can also achieve the function of instant hot water, and the instant hot water can be discharged directly into the water receiving cup without passing through the cup body, avoiding the problem of the instant hot water in the cup body being heated by the conventional food processor, thereby allowing the residual odor of the food preparation in the cup body to enter the instant hot water. Of course, only the corresponding gate valve needs to be provided. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example:

[0030] like Figure 1 、 Figure 2 As shown, a food processor includes a cup body 1 and a crushing device (not shown) arranged in the cup body 1. The cup body 1 includes a cup body base 11 forming a liquid holding cavity and a heating tube 21 for heating the cavity wall of the cup body base. A water pipe 22 is provided on the cavity wall of the cup body base 11 along the trajectory of the heating tube 21. The heating tube 21 is thermally connected to the water pipe 22 to form a temperature control component 2. The temperature control component 2 controls and adjusts the temperature of the liquid in the cup body base.

[0031] A water pipe is provided on the cavity wall of the cup body along the trajectory of the heating pipe. The heating pipe is thermally connected to the water pipe to form a temperature control assembly. Since the water pipe is provided along the trajectory of the heating pipe and the two are thermally connected, the heating pipe will inevitably heat the water pipe during the heating process. Since both are provided on the cavity wall of the cup body, this will inevitably form a temperature control assembly to control and adjust the temperature of the cup body. This is because the heating pipe and the water pipe are controlled as two independent paths, meaning they can operate simultaneously or independently. Therefore, the cup body can be heated by the heating pipe or cooled by the water in the water pipe. In other words, the heating pipe and the water pipe form a temperature control assembly that can heat and cool the liquid in the cup body.

[0032] In this embodiment, the water pipe includes a water outlet, which is connected to the interior of the cup body. In other words, water can be supplied to the cup body through the water pipe, and the water is heated by the heating pipe during the water supply process. At the same time, the heating pipe heats the water that has already entered the cup body. This is equivalent to reusing the heating pipe, improving the utilization efficiency of the heating pipe, shortening the heating time, and overall reducing the time it takes for the food processor to prepare food. Of course, the water pipe must be provided with a water inlet at this time, through which the water used to prepare the food enters the interior of the cup body. As for the water supply method, it is not the main technical solution of this application. It can be directly connected to external tap water or other water supply sources, or it can be provided with a corresponding water supply tank in the food processor. It will not be detailed here. At the same time, the method for the water outlet to communicate with the interior of the cup body can be to provide a corresponding water inlet hole on the cavity wall of the cup body base, or to provide a cup cover or head on the cup body, and to connect to the interior of the cup body through the cup cover or head to allow water to enter.

[0033] In this embodiment, after pulping is completed, the cup body can be cooled by filling the water pipe with water, so that the prepared food is ready to drink. In this case, a corresponding valve can be set between the water outlet and the cup body to prevent water in the water pipe from flowing into the cup body. It is sufficient to only allow the water pipe to be filled with water. In this way, the water pipe can cool the cup body. Of course, a corresponding water path can also be designed. The water from the water outlet can be divided into two controllable paths through a valve body or other devices. One path is connected to the interior of the cup body, and the other path can be connected to other components of the food processor, such as a water tank or a waste water box. In this case, water can be added to the cup body through the water pipe during the operation of the food processor. After the food processor is completed, the cup body can be continuously cooled through the other path of the water pipe, thereby improving the cooling time and effect. Of course, the water outlet can also be provided with a position to flow out to a water receiving cup, so that the food processor can directly prepare ready-to-drink water.

[0034] In this embodiment, the heating pipe and the water pipe are integrally formed to form a temperature control component. The integral forming can be formed by welding or die casting, and then connected to the cavity wall of the cup body. Figure 2 As shown, the heating tube 21 and the water tube 22 are integrally die-cast. Considering the heat transfer effect, the heating tube 21 is arranged below the water tube 22, that is, the water tube surrounds the top of the heating tube. This is conducive to reducing the volume of the entire cup body and reducing interference effects if other devices such as motors are installed at the bottom of the cup body. Furthermore, the temperature control component and the cavity wall of the cup body base are integrally die-cast aluminum, and the heating tube and the water tube are at least partially hidden in the cavity wall of the cup body base. In other words, the heating tube is wrapped in die-cast aluminum, which can transfer heat to the interior of the cup body base more quickly and evenly for food processing.

[0035] Furthermore, in this embodiment, the installation of a corresponding water pipe on the heating tube not only improves heating uniformity but also helps to alleviate localized heat on the heating tube, preventing issues such as burning during food processing. This also prevents the upper portion of the cup mouth from heating too quickly during operation, leading to dry-burning. For smaller cups, a temperature sensor or water inlet and outlet is typically installed on the upper portion of the cup sidewall to facilitate internal water pipe connection and avoid intermittent water flow caused by excessively long water pipe paths.

[0036] For this embodiment, since the heating pipe is arranged together with the water pipe, the heating pipe can be started when water is taken in, avoiding the problem of conventional food processors that need to take in water and then heat in order to solve the problem of dry burning. It can further effectively save time and heat during the water intake process.

[0037] In this embodiment, the wall thickness of the heating tube is no greater than 1mm, and the outer diameter of the water tube is no greater than 8mm. The water tube and heating tube respectively enclose the outer diameter of the lower side wall of the cup body. The inner bottom diameter of the cup body is generally set to be 5mm larger than the outer diameter of the crushing blade on one side. The inner diameter of the heating tube is 0.5mm larger than the outer diameter of the cup body on one side, or it is in close contact with the outer surface of the cup body. The distance between the center of the heating tube and the bottom of the cup body is at least enough to accommodate a water tube during die casting. Too much distance will not facilitate heat transfer to the bottom of the cup body.

[0038] Heating tubes with a wall thickness of 0.5mm and a diameter of 8mm are generally preferred. Heater power is typically kept below 1000W to ensure the water reaches a desired temperature while preventing rapid overheating that could deform or melt plastic components near the cup body. For stainless steel water pipes with an outer diameter of 8mm, standard tubing is preferred, with tight-fitting silicone hoses connecting to the water inlet or outlet. To ensure a secure fit with the die-cast aluminum sidewalls of the aluminum cup body, the heater tube and water pipe should preferably have the same diameter. A uniform diameter, preferably 8mm / 10mm, facilitates die-casting and prevents difficulties in ejecting from unusually shaped molds. The heater tube power should be kept to a minimum. Excessive power can rapidly heat up the upper portion of the cup body, causing melting or deformation of the plastic. Low power can prevent rapid heat transfer to the interior of the cup body to heat the pulping process or water. Positioning the heater tube and water pipe close to the bottom of the cup body improves heat transfer efficiency during pulverization.

[0039] In this embodiment, a temperature protection device mounting portion is provided on the temperature control assembly, and a heating fuse and a temperature sensor are provided on the temperature protection device mounting portion.

[0040] Specific as Figure 3 As shown, a die-cast aluminum notch 5 is provided to enclose the heating tube and water pipe assembly, and the outer lower side is die-cast aluminum 4, which is used to connect the temperature control assembly to the cavity wall of the cup body base. The die-cast aluminum notch 5 is positioned to form a solid width with a certain wall thickness in the middle as the temperature protection device installation part, and the thermal fuse 31, thermal fuse 34 and NTC temperature probe 33 are locked with screws.

[0041] The thermal fuse is placed in the center of the high-temperature area of ​​the heating tube, accurately sensing the temperature and melting it to provide circuit protection when the set temperature is reached; the NTC temperature probe is placed near the high-temperature area of ​​the heating tube as a temperature sensor, accurately detecting the liquid temperature inside the cup body, achieving the set temperature transfer function operation and protecting the normal operation of the machine. The temperature protection device installation part is set on the temperature control component, reducing the processing cost and making the temperature detection more accurate; avoiding inaccurate temperature detection caused by differences in heat transfer efficiency of different materials such as die-cast aluminum, stainless steel, and galvanized steel.

[0042] In this embodiment, the heating tube is provided with a connector for connecting to a power source. The connector includes an insulating magnetic bead and a connecting pin. The insulating magnetic bead extends outside the temperature control assembly by a distance L1, 3 mm ≤ L1 ≤ 10 mm. The water pipe is provided with an external connection port for water circulation. The horizontal distance between the external connection port and the insulating magnetic bead is L2, 10 mm ≤ L2 ≤ 20 mm. The horizontal distance between the external connection port and the connecting pin is L3, 8 mm ≤ L3 ≤ 15 mm.

[0043] Specific as Figure 4 、 Figure 5 As shown, when the temperature control assembly and the cup body are molded, requirements are placed on the extension length of the heating tube and water pipe. The distance L1 from the insulating ceramic bead 211 at the mouth of the heating tube to the outside of the die-cast aluminum is generally between 3-10 mm to prevent the die-casting from damaging the flatness of the end face of the heating tube. The distance L2 from the water pipe extension connection port 221 to the insulating ceramic bead 211 at the mouth of the heating tube is generally between 10-20 mm for plugging in an external silicone water pipe. The distance L3 from the heating pipe connection needle 212 to the water pipe connection port 221 is generally between 8-15 mm for connecting the external and internal wiring harnesses. The water pipe connection port is a certain distance longer than the end face of the heating pipe ceramic bead, effectively ensuring the plug-in travel of the external silicone water pipe and preventing loose plugging that may cause water leakage. The heating pipe connection needle extends a certain distance longer than the water pipe connection port to facilitate welding / spot welding of the internal wiring harness.

[0044] The above embodiments mainly illustrate the present invention by means of die-casting as one-piece molding. Of course, the heating tube, water tube and cup body can also be connected together by other means, such as welding, etc. At this time, the connection method of the specific two-by-two combinations can also be changed. However, the final result does not deviate from the scope of protection of the present invention. For example: die-cast aluminum wraps the heating tube and the outer side of the water tube and is connected to the side wall of the cup body base as one. The heating tube and the water tube can also be welded or fixed together in other ways first, and then placed in the mold for die-casting into one. For example, the die-cast cup body base is welded to the heating tube and water tube assembly to form a cup body; or the heating tube and the water tube are first welded / stamped to form a combination, and then welded to the outer contour of the bottom side wall of the cup body base through flux / filler; for example, the water tube and the heating tube are placed together in a mold for die-casting a cup body assembly, and the water tube can be combined with the heating tube by welding, stamping and positioning.

[0045] The above embodiment is mainly described by taking a single-circle heating tube and a single-circle water tube as an example. As a simple variation of this embodiment, the temperature control component includes multiple heating tubes and / or multiple water tubes, and the heating tubes and the water tubes are spaced apart; or, the heating tubes are arranged in multiple circles on the cavity wall of the cup body base, and / or the water tubes are arranged in multiple circles on the cavity wall of the cup body base, and the single-circle heating tubes and the single-circle water tubes are spaced apart. Figure 6As shown, two water pipes (51, 52) and a heating pipe 53 are provided, with the heating pipe located above the water pipe. In this case, the water pipes 51 and 52 can first be connected in series to form a single water pipe, with the number of turns or connections increased to extend the water path and increase the heating time for a better heating effect. Alternatively, they can be arranged separately, with one pipe used for water intake, one for cooling, or one for outputting ready-to-drink water. To achieve a better effect, the water pipes and the heating pipe are spaced apart.

[0046] After adopting the above technical solution, a water pipe is provided on the cavity wall of the cup body base along the installation path of the heating pipe. The heating pipe and the water pipe are thermally connected to each other to form a temperature control component. Since the water pipe is provided along the installation path of the heating pipe and the two are thermally connected, the heating pipe will inevitably heat the water pipe during the heating process. Since both are provided on the cavity wall of the cup body base, this will inevitably form a temperature control component to control and adjust the temperature of the cup body. This is because the heating pipe and the water pipe are controlled as two independent paths, that is, they can operate simultaneously or independently. Therefore, the cup body can be heated by the heating pipe and cooled by the water in the water pipe.

[0047] In other words, the temperature control component can actually have multiple working combination modes. The heating tube can heat the cup body and water pipe separately, or it can heat the cup body and water pipe at the same time. This looks the same on the surface, but in fact it is determined by whether there is water in the water channel and the cup body.

[0048] In this way, water can be fed into the cup through the water pipe. During the water intake process, it is heated by the heating pipe. At the same time, the heating pipe heats the water that has already entered the cup. This is equivalent to reusing the heating pipe, improving the utilization efficiency of the heating pipe, shortening the heating time, and reducing the overall time it takes for the food processor to prepare food. After the food is prepared, the heating pipe stops heating, and the water in the water pipe can cool the food in the cup. Of course, at this time, the water in the water pipe can be stationary or flowing. If it is flowing, it is only necessary to set a corresponding selection valve at the water outlet of the water pipe so that the water out of the water pipe does not enter the cup.

[0049] In addition, this structure can also achieve the function of instant hot water, and the instant hot water can be discharged directly into the water receiving cup without passing through the cup body, avoiding the problem of the instant hot water in the cup body being heated by the conventional food processor, thereby allowing the residual odor of the food preparation in the cup body to enter the instant hot water. Of course, only the corresponding gate valve needs to be provided.

[0050] In the above embodiments, the temperature control component is disposed on the outer cavity wall of the cup body base. Of course, it can also be disposed on the bottom cavity wall of the cup body base.

[0051] The food processor of the present invention can be a food processor with a motor-undermounted structure, such as a three-stage heating wall-breaking food processor or a frame-type food processor, or a food processor with a motor-overmounted structure, such as a soymilk maker. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
