Fig. 1 to fig. 3 are structural views of a food processor according to an exemplary embodiment of the present invention. Fig. 1 is an exploded perspective view of the food processor, and fig. 2 and 3 are cross-sectional views of the food processor in different states.

The processor can be a wall breaking machine, a juice extractor, a soybean milk machine or other food processing appliances with heating function.

In the present embodiment, the food processor 100 is provided with a whipping device and a heating device, and has the functions of whipping food materials and heating food materials. Furthermore, the food processor 100 is provided with a controller for controlling the operation of the whipping device and the heating device as well as other components.

As shown in fig. 1 to 3, the food processor 100 includes a base 50, a food cup 40 and a sound-proof cover 20. The cooking cup 40 is placed above the base 50, and the sound-proof housing 20 is arranged around the cooking cup 40.

The lower end surface of the cooking cup 40 and the upper end surface of the base 50 can be provided with conductive contacts (e.g., electrical connectors) that are matched with each other. After the cooking cup 40 is placed on the base 50, the conductive contacts are connected, so that the cooking cup 40 is electrically connected with the base 50, and the motor, the power supply (or the power adapter), the controller and the like arranged in the base 50 can respectively provide support for the cutter, the heating resistance wire and the like arranged in the cooking cup 40 in terms of power, power supply, signal control and the like. The knife as used herein is to be understood broadly and may be a crushing blade, a grinding wheel, a broke screw, etc.

In other embodiments, the food processing cup 40 and the base 50 can be an integral body. For example, the cooking cup 40 may be provided as a part of the housing 50 that is not detachable.

The cooking cup 40 may include a cup body 41 and a cup cover 43. The lid 43 is detachably mounted on the cup 41, and encloses a space 410 for receiving and processing food material with the cup 41. In addition to the lid 43 directly covering the upper surface of the cup 41, other lids, such as a second lid 45, a third lid 47, etc., may be provided, which may be used to discharge steam, feed, etc., outward. Steam exiting the cooking cup 40 can enter and accumulate within the sound enclosure 20 if the sound enclosure 20 does not promptly exhaust the steam to the environment.

The sound-proof housing 20 at least surrounds the cup body 41 of the cooking cup 40, so that noise generated by beating in the cup body 41 can reach the external environment after being filtered or shielded twice by the cup body 41 and the sound-proof housing 20. Thus, the noise of the food processor 100 can be reduced.

The soundproof cover 20 may be mounted on an upper surface of the housing 50. In the above mounting manner, the soundproof cover 20 does not cover the base 50 but only covers the main part of the cooking cup 40, which is advantageous for reducing the volume of the soundproof cover 20. For example, an installation groove may be formed on the upper surface of the base 50. The installation of the acoustic enclosure 20 can be accomplished by inserting the pins 224, 244 at the lower end of the acoustic enclosure 20 into the installation slots. In addition, the base 50 and the soundproof cover 20 may be provided with a projection 525 and a fitting hole 225, respectively, and the fixation of the soundproof cover 20 and the base 50 may be reinforced by the engagement of the projection 525 and the fitting hole 225.

The acoustic enclosure 20 may be integrally formed or may be assembled from multiple components. In the embodiment shown in fig. 1 to 3, the main shielding cover 21 of the soundproof cover 20 includes a first cover 22 and a second cover 24, and the second cover 24 is rotatable with respect to the first cover 22. When the cooking cup 40 needs to be moved out or put in, the second cover 24 is only needed to be rotated. In addition, to facilitate the operation of the rotation of the second cover 24, a handle 245 for the user to hold may be provided on the second cover 24. To reduce the height of the handle 245, a recess 243 may be provided on the surface of the second cover 24, and the handle 245 may be disposed in the recess 243.

In addition to the enclosure body 21, the acoustic enclosure 20 includes an exhaust cover 28. The exhaust cover 28 is movably mounted to the housing 21 such that the exhaust cover 28 is still movable relative to the housing 21 when the two are integrally mounted. This, in turn, allows at least two operating positions of the exhaust cover 28, a closed position and an exhaust position. Furthermore, a first magnet 34 may be disposed on the cover 21 and a second magnet 32 may be disposed on the exhaust cover 28 to automatically switch the exhaust cover 28 between the closed position and the exhaust position.

In the non-heating operation mode (e.g., the whipping mode) of the food processor 100, the first magnet 34 and the second magnet 32 attract each other, and the attraction force tightly adheres the exhaust cover 28 to the surface of the cover 21, so that the two are connected in an airtight manner. As shown in fig. 2. At this time, the exhaust cover 28 is in the closed position. The sound enclosure 20 (and the housing 50) isolates the cooking cup 40 within an enclosed or air-tight space. In this state, the noise generated by the whipping in the cooking cup 40 is largely filtered by the soundproof cover 20, and the disturbance to the external environment is extremely small.

In the heating mode of the food processor 100, when the temperature inside the cooking cup 40 (especially the temperature of the first magnet 34) reaches a predetermined value (demagnetizing temperature), for example, 90 degrees celsius, the first magnet 34 starts to be demagnetized. The attractive force between the first magnet 34 and the second magnet 32 begins to decrease or even disappear. When the steam is accumulated to a certain degree, the gas pressure generated by the steam is enough to overcome the reduced adsorption force and the gravity of the exhaust cover 28, and then the exhaust cover 28 is automatically opened, so that an exhaust port G for the steam to pass through is generated between the exhaust cover 28 and the cover body 21. As shown in fig. 3. At this time, the exhaust cover 28 is in the exhaust position. Through this exhaust port G, the cooking cup 40 located in the soundproof cover 20 can exchange gas with the external environment. In this state, the steam generated by heating in the cooking cup 40 can be discharged, and the excessive air pressure in the cooking cup 40 can be avoided.

The loss temperature of the first and second magnets 34, 32 is dependent on their material. The material of the first and second magnets 34, 32 may be selected according to the desired demagnetization temperature. For example, if the desired field loss temperature is 85 to 95 degrees celsius, the material of the first and second magnets 34, 32 can be selected from ndfeb magnets or ferrite magnets. In addition, the temperature of the loss of field should not be too high, and usually should not exceed 95 ℃. This is because too high a temperature of the magnet loss may result in the lid 28 not being opened in time and the air pressure in the cooking cup 40 being too high.

To facilitate the mounting of the exhaust cover 28 to the housing 21, a bracket 26 may be provided. The bracket 26 includes a side wall 261 and a top wall 263. The exhaust cover 28 is mounted to an upper surface of the top wall 263. The lower end of the sidewall 261 abuts against the upper end of the cooking cup 40, so that the sidewall 261, the top wall 263 of the bracket 26 and the upper end of the cooking cup 40 jointly enclose a steam channel 268. The steam exiting the cooking cup 40 is confined within the steam passageway 268 and cannot enter other areas of the enclosure 21.

The presence of the steam channel 268 allows steam to be confined above the cooking cup 40 without entering the sides of the cooking cup 40, thereby facilitating the user to view the conditions inside the cooking cup 40 from the sides. In addition, the accumulation of steam within the steam channel 268 also facilitates subsequent venting of the steam.

The side wall 261 of the bracket 26 may be provided with a hook 264, and the bracket 26 may be fixed to the cover 21 by the hook 264 and a matching structure provided on the cover 21. In other embodiments, the bracket 26 may be fixed by other forms of locking structures, and the bracket 26 may be integrally formed with the cover 21.

The exhaust cover 28 is provided with a limit hook 286, and correspondingly, the top wall 263 of the bracket 26 is provided with a limit hole 266. The exhaust cover 28 can be mounted on the bracket 26 by the engagement of the limit hooks 286 with the limit holes 266. The limit catch 286 comprises a lever portion 2861 and a latching hook portion 2863, wherein the length of the lever portion 2861 is significantly greater than the thickness of the top wall 263 of the bracket 26, which results in: after the limit hooks 286 are engaged with the limit holes 266, the exhaust cover 28 is still allowed to move up and down within a certain range relative to the bracket 26. The exhaust cap 28 is raised and lowered a distance H substantially equal to the difference between the length of the stem 2861 and the thickness of the top wall 263 of the support 26.

The positioning of the positioning hooks 286 and the positioning holes 266 enables the exhaust cover 28 to be installed on the cover body 21 in a lifting manner. In other embodiments, the exhaust cover 28 may also be rotatably mounted to the housing 21. The exhaust cover and the cover body are provided with the magnets, so that the exhaust cover can be automatically opened and closed.

The top wall 263 of the bracket 26 is recessed downwardly to form a magnet mounting portion 265. The lower surface of the magnet mounting portion 265 is closer to the cooking cup 40 than the other portion of the top wall 263, and the first magnet 34 is mounted on the lower surface of the magnet mounting portion 265. The first magnet 34 mounted on the lower surface of the magnet mounting portion 265 is exposed to the steam passage 268. This allows the steam discharged from the cooking cup 40 to quickly reach the first magnet 34 and conduct the high temperature to the first magnet 34. The recess 267 formed by the recess on the upper surface of the magnet mounting portion 265 is used to accommodate the second magnet 32 fixed on the exhaust cover 28.

To facilitate the mounting of the second magnet 32, a fixing bracket 27 may be provided. The fixing frame 27 is substantially annular, and a receiving hole 273 is formed at the center thereof. The second magnet 32 is placed in the receiving hole 273, and the bottom wall of the receiving hole 273 supports the lower surface of the second magnet 32. The lower surface of the exhaust cover 28 is formed with a press-contact portion 287 projecting downward. The press-contact portion 287 is pressed against the upper surface of the second magnet 32 after the fixing frame 27 is mounted to the exhaust cover 28.

A spring 36 may also be disposed between the bracket 26 and the vent cover 28 in a compressed state. The elastic member 36 may provide a pushing force for opening the exhaust cover 28 after the first magnet 34 is demagnetized. In the present embodiment, the elastic member 36 is a spring. In other embodiments, the resilient member 36 may be a torsion spring, for example, when the exhaust cover 28 is rotatably mounted.

To facilitate positioning and mounting of the elastic member 36, an annular spring receiving portion 275 may be provided at the outer edge of the fixing frame 27. The spring receiving portion 275 has a downward opening through which the upper end of the elastic member 36 enters the spring receiving portion 275 and abuts against the upper wall of the spring receiving portion 275. The lower end of the elastic member 36 is pressed against the upper surface of the concave chamber 267.

A seal 62 may be provided between the lower surface of the exhaust cover 28 and the bracket 26 to enhance the air-tightness between the exhaust cover 28 and the bracket 26. The sealing member 62 may be mounted on a lower surface of the exhaust cover 28 and may be raised and lowered with the exhaust cover 28. The material of the sealing member 62 may be soft glue.

Furthermore, a sealing member 64 may be disposed at the contact portion between the holder 26 and the cooking cup 40, and a sealing member 66 may be disposed at the contact portion between the holder 26 and the cover 21. The material of the sealing members 64, 66 may be soft glue.

In the foregoing embodiment, the magnet made of a specific material is selected to realize the demagnetization of the exhaust cover at a predetermined temperature, so as to open the exhaust cover and discharge steam in time. In other embodiments, at least one of the magnets may be configured as an electromagnet, and the electromagnet is de-energized by de-energizing at a predetermined temperature, thereby achieving automatic opening of the exhaust cover and timely discharge of the steam.

For example, the electromagnet may be wired to a controller within the housing 50. A temperature sensing element is typically disposed within the cooking cup 40 for measuring the temperature within the cup body 41. According to the temperature obtained by the temperature sensing element, the controller controls the on and off of the current in the electromagnet. When the temperature measured by the temperature sensing element does not reach the preset temperature, the controller keeps the electromagnet electrified, so that the exhaust cover 28 is in sealed connection with the cover body 21. When the temperature measured by the temperature sensing element reaches a preset temperature, the controller enables the electromagnet to be powered off and demagnetized, and further an exhaust port G for steam to pass through can be generated between the exhaust cover 28 and the cover body 21.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
