Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processing machine with good sealing effect. Background Art

[0002] Existing food processors usually include a main unit and a cup assembly. The cup assembly is provided with a stirring element that is transmission-connected to a motor in the main unit. When a user uses the food processor to process food, the user places the food in the cup assembly, and then the motor drives the stirring element at high speed to process the food. In order to improve the function of the food processor, a heating plate is usually arranged under the cup body, and the food in the cup body is heated by the heating of the heating plate. At the same time, in order to prevent the heat on the heating plate from being transferred to the main machine in large quantities, an insulating sleeve is arranged under the heating plate to separate the main machine from the heating plate. However, after the insulating sleeve is connected to the heating plate, there will be a gap between the two. In order to prevent the food slurry and the like from entering the insulating sleeve through the gap during food processing, the existing patent discloses a stirring knife seat assembly, which is provided with two ring ribs extending upward on the insulating sleeve, and the sealing ring is fixed in the grooves formed by the two rings. At the same time, in order to better clean the cup body and the knife seat, the knife seat is usually arranged to be detachably connected to the cup body. When the knife seat is removed and soaked for cleaning, the sealing requirement of the knife seat is greater. Although it can achieve the sealing effect, the structure is relatively complicated, resulting in an increase in the manufacturing cost of the whole machine, and the assembler has more assembly steps during assembly, resulting in a low assembly efficiency. In addition, as the number of structural components increases, the sealing effect of the knife seat becomes worse, which easily causes water stains and the like to enter the knife seat during cleaning. Utility Model Content

[0003] The utility model aims to provide a food processing machine with good sealing effect, so as to solve the problems in the existing food processing machine that the sealing structure of the heat insulation sleeve and the heating plate is complicated, resulting in increased manufacturing cost, low assembly efficiency and poor sealing effect.

[0004] To achieve the above-mentioned purpose, the utility model provides a food processing machine with good sealing effect, including a main machine and a cup body assembly, the cup body assembly includes a cup body with upper and lower openings and a knife seat arranged at the lower end opening of the cup body, the knife seat includes a heating plate and a heat insulation sleeve arranged below the heating plate, a stirring knife assembly is provided in the middle of the heating plate, the stirring knife assembly includes a surrounding plate extending downward from the bottom wall of the heating plate, a bearing arranged in the surrounding plate and a knife shaft passing through the bearing, the heat insulation sleeve is provided with an upwardly extending boss, the boss is provided with an annular positioning rib extending upward and surrounding the outer side of the surrounding plate, and a sealing ring is clamped between the positioning rib and the bottom wall of the heating plate.

[0005] The present application provides an annular positioning rib extending upward and surrounding the outer side of the enclosure on the boss, and a sealing ring is clamped between the positioning rib and the bottom wall of the heating plate. On the one hand, the sealing between the positioning rib and the heating plate is achieved, and the deformable performance of the sealing ring is used to greatly improve the tightness of the fit between the positioning rib and the heating plate, effectively preventing slurry or food from entering the thermal insulation sleeve through the gap between the positioning rib and the heating plate during food processing, causing internal parts to become damp or even damaged, thereby improving the protection of parts in the thermal insulation sleeve. At the same time, the positioning rib extends upward, so that food slurry can be prevented from further spreading into the thermal insulation sleeve under the obstruction of the positioning rib, thereby further improving the sealing effect. On the other hand, The surface can achieve effective isolation between the positioning rib and the heating plate, play a role in buffering and shock absorption, and avoid direct contact between the positioning rib and the heating plate, which causes the motor to vibrate when rotating at high speed, causing the positioning rib and the heating plate to collide relative to each other, thereby generating a large noise. It helps to improve the shock absorption and noise reduction effect and enhance the user experience. At the same time, compared with the existing installation method of the sealing ring, it only needs to clamp and install the sealing ring while installing the insulation sleeve and the heating plate. The installation is more convenient and quick, and the structure of the sealing ring and the insulation sleeve is simplified, so that the sealing ring can achieve sealing and buffering and shock absorption while improving production efficiency and reducing production costs. Preferably, the knife holder is detachably connected to the cup body, which is convenient for users to clean the knife holder and can ensure that the knife holder is cleaned more thoroughly, avoiding the situation where dirt accumulates on the knife holder for a long time and causes the knife holder to produce odor or even mold, and the boss and the enclosure plate realize axial clamping of the sealing ring. When the insulation sleeve and the heating plate are assembled, an axially fixed fixing will be provided, thereby increasing the clamping force on the sealing ring, thereby further improving the sealing of the knife holder, preventing cleaning water and the like from entering the knife holder, and realizing protection of various components in the knife holder.

[0006] In a preferred implementation of a food processor with good sealing effect, an annular groove is provided on the bottom wall of the heating plate, and the sealing ring is accommodated in the annular groove.

[0007] By providing an annular groove on the bottom wall of the heating plate and accommodating the sealing ring in the annular groove, the sealing ring can be installed and fixed, thereby ensuring the reliability of the position of the sealing ring, avoiding the situation where the sealing ring is displaced after long-term use, resulting in the sealing effect of the sealing ring being deteriorated or even failing, thereby improving its sealing reliability.

[0008] In a preferred implementation of a food processor with good sealing effect, the depth of the annular groove is less than the thickness of the sealing ring, so that the bottom end of the sealing ring is exposed outside the annular groove.

[0009] By setting the depth of the annular groove to be smaller than the thickness of the sealing ring so that the bottom end of the sealing ring is exposed in the annular groove, the top end of the positioning rib can more conveniently abut against the bottom end of the sealing ring when the insulation sleeve is assembled with the heating plate, thereby avoiding the situation where the bottom end of the sealing ring is located in the annular groove, which causes the positioning rib to adapt to the size of the annular groove and to extend into the annular groove to abut against the sealing ring, resulting in a more complicated assembly process of the insulation sleeve and low assembly efficiency. This helps to further improve assembly efficiency.

[0010] In a preferred implementation of a food processor with good sealing effect, the top wall of the boss is further provided with a positioning ring extending into the enclosure.

[0011] By providing a positioning ring extending into the enclosure on the top wall of the boss, the top surface of the positioning ring raises the height of the top surface of the boss, so that even after the slurry passes through the through hole for the knife shaft to pass through, it still needs to pass over the higher positioning ring to contact the enclosure, thereby blocking the slurry on the food, which helps to further improve the blocking and sealing effect of the slurry.

[0012] In a preferred implementation of a food processor with good sealing effect, the outer side wall of the positioning ring abuts against the inner side wall of the enclosure.

[0013] By setting the outer wall of the positioning ring to abut against the inner wall of the enclosure, on the one hand, a sealing effect is formed between the positioning ring and the enclosure, so that even if food slurry etc. exceeds the obstruction of the positioning ring and overflows outward, the sealing between the positioning ring and the enclosure can prevent the slurry from flowing downward through the gap between the two, thereby further improving the sealing effect; on the other hand, when assembling the insulation sleeve and the heating plate, the alignment of the positioning ring and the enclosure can achieve accurate and rapid alignment of the two, which helps to further improve the assembly efficiency.

[0014] In a preferred implementation of a food processor with good sealing effect, the mixing blade assembly also includes an upper shaft seal arranged above the bearing and a lower shaft seal arranged below the bearing, the outer wall of the lower shaft seal abuts against the inner wall of the enclosure, and the bottom wall abuts against the top wall of the positioning ring.

[0015] By setting a lower shaft seal, the outer wall of the lower shaft seal abuts against the inner wall of the enclosure, and the bottom wall abuts against the top wall of the positioning ring, so that the lower shaft seal, the enclosure and the positioning ring achieve a first layer of sealing, and at the same time, the positioning rib and the bottom wall of the heating plate achieve a second layer of sealing, thereby achieving double sealing, further improving the sealing effect, and further preventing slurry or food from entering the insulation sleeve through the gap between the positioning rib and the heating plate, causing internal components to become damp or even damaged, thereby improving the protection of components in the insulation sleeve.

[0016] In a preferred implementation of a food processing machine with good sealing effect, a sealing ring is clamped between the enclosure plate and the positioning rib.

[0017] By clamping a sealing ring between the enclosure and the positioning rib, on the one hand, a first layer of sealing is formed between the enclosure and the positioning rib, and at the same time, a second layer of sealing is achieved between the positioning rib and the bottom wall of the heating plate, thereby achieving double sealing and further improving the sealing effect; on the other hand, the enclosure and the positioning rib can be positioned to make the alignment of the insulation sleeve and the heating plate more precise, which helps to further improve the assembly efficiency.

[0018] In a preferred implementation of a food processor with good sealing effect, the sealing ring and the sealing ring are integrally formed.

[0019] By forming the sealing ring and the sealing ring as an integral part, the sealing ring and the sealing ring can be installed and positioned synchronously during assembly, saving installation steps and helping to further improve assembly efficiency. In addition, the sealing ring is clamped between the positioning rib and the bottom wall of the heating plate, which can achieve vertical positioning of the sealing ring and ensure its position stability.

[0020] In a preferred implementation of a food processing machine with good sealing effect, the outer wall of the enclosure abuts against the inner wall of the positioning rib.

[0021] By setting the outer wall of the enclosure to abut against the inner wall of the positioning rib, the enclosure and the positioning rib also achieve a sealing effect. Combined with the sealing of the positioning rib and the bottom wall of the heating plate, a double sealing effect is achieved, which can further enhance the barrier effect on food slurry.

[0022] In a preferred implementation of a food processor with good sealing effect, the heating plate is further provided with a limiting rib extending downward and located outside the positioning rib, and the inner side wall of the limiting rib abuts against the outer side wall of the positioning rib.

[0023] By providing the heating plate with a limiting rib extending downward and located on the outside of the positioning rib, and the inner wall of the limiting rib abuts against the outer wall of the positioning rib, the heating plate and the insulation sleeve can be accurately and quickly aligned with each other during installation with the help of the positioning cooperation of the limiting rib and the positioning rib, which helps to further improve the assembly efficiency.

[0035] The present application provides an annular positioning rib 211 extending upward and surrounding the outer side of the enclosure 11 on the boss 21, and a sealing ring 5 is clamped between the positioning rib 211 and the bottom wall of the heating plate 1. On the one hand, the sealing between the positioning rib 211 and the heating plate 1 is achieved, and the tightness of the fit between the positioning rib 211 and the heating plate 1 is greatly improved by virtue of the deformable performance of the sealing ring 5, which effectively prevents slurry or food from entering the insulation sleeve 2 through the gap between the positioning rib 211 and the heating plate 1 during food processing, causing the internal parts to become damp or even damaged, thereby improving the protection of the parts in the insulation sleeve 2. At the same time, the positioning rib 211 extends upward, so that food slurry can be prevented from further spreading into the insulation sleeve 2 under the obstruction of the positioning rib 211, further improving Sealing effect; on the other hand, it can achieve effective isolation between the positioning rib 211 and the heating plate 1, play a role in buffering and shock absorption, and avoid direct contact between the positioning rib 211 and the heating plate 1, which causes the motor to vibrate when rotating at high speed, causing the positioning rib 211 and the heating plate 1 to collide with each other, thereby generating a large noise, which helps to improve the shock absorption and noise reduction effect and enhance the user experience; at the same time, compared with the existing installation method of the sealing ring 5, it only needs to clamp and install the sealing ring 5 while installing the insulation sleeve 2 and the heating plate 1, which makes the installation more convenient and quick, and at the same time simplifies the structure of the sealing ring 5 and the insulation sleeve 2, so that the sealing ring 5 can achieve sealing and buffering and shock absorption while improving production efficiency and reducing production costs. Preferably, the knife holder is detachably connected to the cup body, which is convenient for users to clean the knife holder and can ensure that the knife holder is cleaned more thoroughly, avoiding the situation where dirt accumulates on the knife holder for a long time and causes the knife holder to produce odor or even mold, and the boss 21 and the surrounding plate 11 realize 5-axial clamping of the sealing ring. When the insulation sleeve 2 and the heating plate 1 are assembled, an axially fixed fixing will be provided, thereby increasing the clamping force on the sealing ring, thereby further improving the sealing of the knife holder, preventing cleaning water and the like from entering the knife holder, and realizing protection of various components in the knife holder.

[0036] It should be noted that the present application does not specifically limit the fixing of the sealing ring 5.

[0039] By setting the depth of the annular groove 12 to be smaller than the thickness of the sealing ring 5, so that the bottom end of the sealing ring 5 is exposed outside the annular groove 12, the top end of the positioning rib 211 can more conveniently achieve abutment with the bottom end of the sealing ring 5 when the insulation sleeve 2 is assembled with the heating plate 1, avoiding the situation where the bottom end of the sealing ring 5 is located in the annular groove 12, resulting in the positioning rib 211 needing to adapt to the size of the annular groove 12 and needing to extend into the annular groove 12 to achieve abutment with the sealing ring 5, causing the assembly process of the insulation sleeve 2 to be more cumbersome and the assembly efficiency to be low, which helps to further improve the assembly efficiency. It should be noted that the abutment between the above-mentioned structures can be direct contact between surfaces, or it can be indirect contact achieved with the help of other structures such as shock-absorbing pads.

[0040] Of course, in the present application, the sealing ring 5 is not limited to being arranged in the annular groove 12, and it can be directly bonded to the bottom wall of the heating plate 1 by gluing or other methods, which will not be elaborated here.

[0045] As a preferred embodiment of this embodiment, Figure 3 , Figure 4 As shown, the stirring blade assembly also includes an upper shaft seal 7 arranged above the bearing 4 and a lower shaft seal 6 arranged below the bearing 4. The outer wall of the lower shaft seal 6 abuts against the inner wall of the enclosure 11, and the bottom wall abuts against the top wall of the positioning ring 212.

[0046] By setting the lower shaft seal 6, the outer wall of the lower shaft seal 6 abuts against the inner wall of the enclosure 11, and the bottom wall abuts against the top wall of the positioning ring 212, so that the lower shaft seal 6 and the enclosure 11 and the positioning ring 212 achieve a first layer of sealing, and at the same time, the positioning rib 211 and the bottom wall of the heating plate 1 achieve a second layer of sealing, thereby achieving double sealing, further improving the sealing effect, and further preventing slurry or food from entering the insulation sleeve 2 through the gap between the positioning rib 211 and the heating plate 1, causing the internal components to become damp or even damaged, thereby improving the protection of the components in the insulation sleeve 2.

[0049] It should be noted that the present application does not specifically limit the relative relationship between the sealing ring and the sealing ring 5 , which can be separately molded and then installed separately. As a preferred embodiment of the present application, the sealing ring and the sealing ring 5 are integrally molded.

[0050] By forming the sealing ring and the sealing ring 5 as an integral part, the sealing ring and the sealing ring 5 can be installed and positioned synchronously during assembly, which saves installation steps and helps to further improve assembly efficiency.
