Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and in particular to a food processor. Background Art

[0002] A food processor is a multifunctional small appliance commonly found in modern home kitchens. It integrates multiple functions such as grinding, stirring, and heating. It can break the cell walls of ingredients, thereby more effectively releasing the nutrients in the ingredients and making drinks and dishes with a more delicate taste and richer nutrition.

[0003] Most food processors currently on the market require heating for cooking. Thoroughly heating ingredients allows for more even grinding, better release of nutrients, and a more delicate taste. However, food processors typically operate at a heating power of 600-800W, which is inefficient. This means that fully heating ingredients often takes a considerable amount of time, forcing users to wait excessively. Furthermore, increasing the heating power can lead to the food becoming scorched.

[0004] For the above problems, no effective solution has been proposed yet. Utility Model Content

[0039] A food processor is a multifunctional kitchen appliance that can perform a variety of food processing tasks, including blending, beating, grinding, mincing, and juicing, greatly simplifying food preparation in the kitchen. Food processors include blenders, soymilk makers, juicers, blenders, coffee machines, and more.

[0040] Combine Figures 1 to 3 As shown, according to a specific embodiment of the present application, a food processor is provided.

[0041] Specifically, the food processor includes: a cup body 1, a lid body 2, a silent cover 3, and a micro-pressure valve structure 5. The cup body 1 has a cooking chamber; the lid body 2 is connected to the cup body 1; the silent cover 3 is connected to the lid body 2, and the silent cover 3 shields at least a portion of the cup body 1 and / or at least a portion of the lid body 2. The silent cover 3 includes a silent cover bead 4, which is disposed on the top of the lid body 2; the micro-pressure valve structure 5 is disposed on at least one of the silent cover bead 4 and the lid body 2. The micro-pressure valve structure 5 has a closed state, which seals the cooking chamber, and an open state, which connects the cooking chamber to the atmosphere.

[0042] It should be further explained that the micro-pressure valve structure 5 has a closed state that seals the cooking chamber when the pressure in the cooking chamber is less than a critical value, and the micro-pressure valve structure 5 has an open state that connects at least part of the cooking chamber to the atmosphere when the pressure in the cooking chamber is greater than or equal to the critical value.

[0043] By applying the technical solution of the present invention, a micro-pressure valve structure 5 is provided on the silent cover bead 4 or the cover body 2, and the micro-pressure valve structure 5 is switched between the closed and open states. This can enable the food processor to improve the heating efficiency by increasing the pressure inside the container without increasing additional heating power, shorten the cooking time, and prevent the ingredients from sticking to the bottom, thereby improving the quality and taste of the food, reducing energy consumption, and improving the user experience.

[0044] Specifically, if Figure 1 As shown, the micro-pressure valve structure 5 comprises a valve body 51 and an opening / closing member 53. A first exhaust channel 52 is formed within the valve body 51. The first end of the first exhaust channel 52 communicates with the cooking chamber, and the second end communicates with the atmosphere. The opening / closing member 53 is positioned within the first exhaust channel 52 and is movably disposed relative to the valve body 51. The opening / closing member 53 has a blocking position and at least one escape position. In the blocking position, the opening / closing member 53 blocks the first exhaust channel 52, closing the micro-pressure valve structure 5. In the escape position, the opening / closing member 53 at least partially opens the first exhaust channel 52, opening the micro-pressure valve structure 5. The automatic switching of the opening / closing member 53 between the blocking and escape positions enables dynamic control of the air pressure in the cooking chamber. Through this switching mechanism, the micro-pressure valve structure 5 can automatically adjust the internal air pressure at different stages of cooking, ensuring efficient and high-quality cooking while avoiding safety hazards.

[0045] like Figure 1 As shown, the micro-pressure valve structure 5 is positioned in the middle of the silent cover bead 4. A first exhaust channel 52 is a channel within the micro-pressure valve structure 5 for releasing excess air pressure. Designed to be elongated and inclined at a predetermined angle, it automatically opens and closes under the force of gravity of an opening / closing member 53. The first end of the first exhaust channel 52 communicates with the cooking chamber, allowing steam to enter. However, during the initial cooking phase or when the air pressure has not reached a preset value, the opening / closing member 53 is in a blocked position. The opening / closing member 53 (a small ball in this embodiment) uses its own gravity to block the first exhaust channel 52, confining the steam within the cooking chamber and creating a micro-pressure environment.

[0046] like Figure 2As shown, during the cooking process, as the temperature in the cooking chamber rises, the steam pressure gradually increases. When the pressure exceeds the closing threshold of the opening and closing member 53, the opening and closing member 53 is lifted up by the steam pressure and pushed open to the avoidance position. At this time, the first exhaust channel 52 is at least partially open, and the micro-pressure valve structure 5 is in an open state. At this time, the second end of the first exhaust channel 52 is connected to the atmosphere, and excess steam is released into the atmospheric environment, avoiding potential safety hazards caused by excessive internal pressure, such as equipment explosion or food sticking to the bottom. When the pressure drops below the safe level, the opening and closing member 53 naturally falls back and re-seals the first exhaust channel 52, maintaining a micro-pressure environment and improving heating efficiency.

[0047] Furthermore, the valve body 51 extends along a first direction, extending vertically from the first end of the first exhaust passage 52 to the second end of the first exhaust passage 52, from the cooking chamber toward the atmosphere. The projected area of ​​the valve body 51 along this first direction gradually increases, meaning that the valve body 51 is structured similarly to a tapered passage, gradually widening the exhaust path from the cooking chamber to the atmosphere. This configuration of the valve body structure utilizes geometric variations to optimize steam flow and the opening and closing of the opening and closing member 53. The smaller inlet section effectively restricts the steam flow until the pressure is sufficient to overcome the weight of the opening and closing member 53, prompting it to move relative to the valve body 51. The gradually increasing outlet section facilitates smooth steam discharge, avoiding sudden changes in airflow and reducing noise during discharge. It also facilitates rapid steam diffusion and prevents the formation of excessive pressure gradients at the outlet, which could affect the proper functioning of the opening and closing member.

[0048] Optionally, a bearing portion is formed at the first end of the first exhaust channel 52, and when the opening and closing member 53 abuts the bearing portion, the opening and closing member 53 is located in a blocking position. The bearing portion is a structure that can support the opening and closing member 53, such as a small platform or a raised portion. The function of the bearing portion is to provide a positioning and support point for the opening and closing member 53. When the opening and closing member 53 abuts the bearing portion, the opening and closing member 53 is in a blocking position, effectively closing the first exhaust channel 52, preventing steam from flowing out, and maintaining a micro-pressure environment in the cooking chamber. When the pressure is large enough, the opening and closing member 53 leaves the bearing portion, and the steam is discharged through the first exhaust channel 52. The design of the bearing portion needs to take into account the hardness and wear resistance of the material to withstand the gravity and steam pressure of the opening and closing member 53 while maintaining its stability and reliability.

[0049] Furthermore, the valve body 51 is arranged on the silent cover bead 4, and the silent cover bead 4 is composed of an upper shell and a lower shell. The lower shell is connected to the first exhaust channel 52. The upper shell and the lower shell can be connected by one-piece molding or welding to form an inseparable whole, or can be connected simply and quickly by snap-on connection.

[0050] like Figure 1As shown, the lid 2 has a second exhaust channel 21. When the opening / closing member 53 is in the avoidance position, one end of the second exhaust channel 21 communicates with the first exhaust channel 52, and the other end of the second exhaust channel 21 communicates with the cooking chamber, thereby connecting the first exhaust channel 52 with the cooking chamber. The second exhaust channel 21 is larger than the first exhaust channel 52. The first exhaust channel and the opening / closing member 53 are designed to cooperate. The size and weight of the opening / closing member 53 determine the minimum opening size of the channel to ensure that the opening / closing member 53 can be accurately opened when a micro-pressure state is reached. The second exhaust channel 21 does not need to cooperate with the opening / closing member 53 and can be designed to be wider. When the opening / closing member 53 is pushed open, the second exhaust channel 21 communicates with the first exhaust channel 52, allowing a large amount of steam to be quickly discharged, helping to quickly adjust the air pressure in the cooking chamber. At the same time, when the opening / closing member 53 is not opened, the second exhaust channel 21 can serve as a backup exhaust path to ensure safe operation of the device.

[0051] Specifically, the valve body 51 and the silent cover bead 4 are integrally formed. This significantly enhances the connection strength and sealing between the two components, preventing problems such as loosening and leakage that may occur after prolonged use, and improving the stability and reliability of the entire micro-pressure valve structure 5. Furthermore, the integrated manufacturing method of the valve body 51 and the silent cover bead 4 reduces the number of parts, lowers production costs, optimizes internal space, and makes the overall design of the device more compact.

[0052] In an exemplary embodiment, the valve body 51 is arranged on the cover body 2, and the silent cover bead 4 is provided with an air flow hole connected to the atmosphere on the side facing the cover body 2. When the opening and closing member 53 is in the avoidance position, the first exhaust channel 52 is connected to the air flow hole, so that the air flow in the cooking chamber passes through the cover body 2 and the silent cover bead 4 in turn and flows into the atmosphere.

[0053] Specifically, the airflow hole is connected to the first exhaust channel 52 through an internal channel, forming an airflow path from the cooking chamber to the atmosphere. When the opening and closing member 53 (such as a small ball) is pushed to the avoidance position due to increased internal pressure, the first exhaust channel 52 is opened, and the airflow hole becomes a pressure release outlet, allowing overpressure gas to be quickly discharged. The combination of the airflow hole and the first exhaust channel 52 forms a complete micro-pressure control system, which not only ensures that the food processor reaches and maintains the required micro-pressure state during cooking, but also quickly releases pressure when the pressure rises abnormally.

[0054] Specifically, the valve body 51 is integrally formed with the lid 2. The integrally formed valve body 51 and lid 2 enhance the sealing performance of the connection portion, can better resist pressure changes, and avoid affecting the cooking effect due to weak structure or leakage at the seam.

[0055] Specifically, a soundproof cavity 6 is formed between the silent cover 3 and the lid body 2. The soundproof cavity 6 is divided into two parts, left and right, by the silent cover bead 4. The soundproof cavity 6 is connected to the atmosphere. The valve body 51 is provided on the lid body 2. When the opening and closing member 53 is in the avoidance position, the first exhaust channel 52 is connected to the soundproof cavity 6. The opening and closing member 53 controls the opening and closing of the first exhaust channel 52 by sensing the changes in the air pressure in the cooking cavity. When the air pressure in the cooking cavity exceeds a preset micro-pressure value, the opening and closing member 53 is pushed open, allowing the gas to enter the soundproof cavity 6 through the first exhaust channel 52. The soundproof cavity 6 can further reduce the noise generated when the gas is discharged from the first exhaust channel 52. After the gas enters the soundproof cavity 6, the space and structural design in the cavity can effectively attenuate the sound, reduce the leakage of noise, and provide a quieter use environment for the user.

[0056] Specifically, a soundproof cavity 6 is formed between the silent cover 3 and the lid 2. The silent cover bead 4 has a first connecting portion, and the lid 2 has a second connecting portion. At least a portion of the first connecting portion extends into the second connecting portion and snaps into place. This snapping connection provides a more secure connection between the first and second connecting portions. This connection reduces the possibility of loosening of components during prolonged use or when subjected to external impact, thereby improving the overall stability and durability of the device. An elastic seal 7 is provided between the first and second connecting portions to isolate the first exhaust passage 52 from the soundproof cavity 6. In this embodiment, the elastic seal 7 is a sealing ring. It fills the slight gap between the first and second connecting portions, forming an effective seal to prevent steam leakage from the cooking chamber during cooking and prevent external impurities such as dust from entering the device, ensuring a clean interior and a stable micro-pressure environment. The provision of the elastic seal 7 ensures that when the opening and closing member 53 is closed, it effectively blocks direct communication between the first exhaust passage 52 and the soundproof cavity 6. Only when the opening and closing member 53 is correctly opened, the first exhaust channel 52 will be connected to the sound insulation cavity 6, thereby achieving safe pressure release.

[0057] Specifically, the silent cover bead 4 is connected to the lid 2 via a threaded connection. This threaded connection ensures stability and securement during use. By tightening the threads, the silent cover bead 4 is securely fastened to the lid 2, effectively preventing steam or air leakage. This maintains a micro-pressure environment within the cooking chamber, improving heating efficiency and cooking results. This also prevents the silent cover bead 4 from falling off due to vibration or external forces during stirring or heating, ensuring safe operation of the device.

[0058] In an alternative embodiment, an opening is designed at a suitable location on the top or side of the silent cover 3. This opening is directly connected to the atmosphere. To control airflow, an adjustable airflow control device, such as a simple valve, can be installed at the opening. This device can be opened automatically or manually when the device is heating, allowing air to escape. When not heating or when heating is complete, it closes to reduce sound transmission and enhance the quiet effect. The opening in the silent cover 3 ensures that the air pressure in the cooking chamber can be balanced during the heating process to prevent overpressure. It also maintains a relatively sealed interior when not heating to reduce sound transmission. The micro-pressure valve structure 5 may accumulate food debris and grease. In particular, if the first end of the first exhaust channel 52 is blocked, the opening and closing member 53 cannot be pushed open, potentially leading to excessive pressure inside the cup body and the risk of explosion or rupture. The opening design allows the opening to open in the event of a malfunction of the micro-pressure valve structure 5, quickly venting the airflow in the cooking chamber and preventing overpressure or negative pressure.

[0059] In another alternative embodiment, an opening is designed at a suitable location on the top or side of the silent cover 3. One end of the opening is directly connected to the atmosphere, while the other end is connected to the cooking chamber. The micro-pressure valve structure 5 is positioned within the opening of the silent cover 3. In this case, the silent cover bead 4 merely serves to tightly connect to the food processor lid 2. During the initial cooking phase or when the air pressure has not reached the preset value, the opening and closing member 53 is in the blocking position. The opening and closing member 53, relying on its own gravity, blocks the first exhaust passage 52. At this point, the opening of the silent cover 3 is blocked, trapping steam within the cooking chamber and creating a micro-pressure environment. As the temperature within the cooking chamber rises, the steam pressure gradually increases. When the pressure exceeds the closing threshold of the opening and closing member 53, the steam pressure pushes it up to a safe position. At this point, the first exhaust passage 52 is at least partially opened, and the micro-pressure valve structure 5 is in the open position. The opening of the silent cover 3 is open, allowing gas to be discharged directly to the atmosphere, reducing the pressure within the cooking chamber, improving heating efficiency, and preventing food from burning. In this embodiment, the silent cover bead 4 is designed as a hemispherical structure, made of high-temperature and wear-resistant materials to prevent users from direct contact with high-temperature components during operation and avoid burns. After processing, ensure that the food processor is completely stopped, manually pinch the silent cover bead 4 to lift it and separate it from the lid 2, and then directly open the food processor to pour out the food in the cooking chamber.

[0060] It should be further explained that the food processor also includes a handle 8 and a power interface 9.

[0061] like Figure 3As shown, the handle 8 is connected to the cup body 1 and is set on the left side of the cup body 1. The handle 8 is designed in a U-shape and has a non-slip design, allowing users to easily pick up or move the food processor. In particular, when the device needs to be repositioned or cleaned after use, the handle 8 provides a stable grip, enhancing the convenience and safety of operation. During use, the handle 8 can prevent the user from directly contacting hot or live parts, especially after micro-pressure cooking, when high temperatures may remain in the cooking chamber. The handle 8 design ensures that the user will not be burned, improving overall safety.

[0062] Power port 9, located at the bottom of the food processor, is the key point for connecting the food processor to an external power source. It provides the necessary power to the device, ensuring the proper operation of the motor, heating element, and micro-pressure valve structure 5 to meet cooking needs. Power port 9 is waterproof to prevent electrical malfunctions caused by liquid splashes.

[0063] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0064] By installing a micro-pressure valve structure on the silent cover bead or lid, at the beginning of cooking or when the air pressure has not reached the preset value, the opening and closing member is in the blocking position. The opening and closing member relies on its own gravity to block the first exhaust channel, and the micro-pressure valve structure is closed, so that the steam is confined within the cooking chamber, creating a micro-pressure environment. As the temperature in the cooking chamber rises, the steam pressure gradually increases. When the pressure exceeds the closing threshold of the opening and closing member, the opening and closing member is lifted by the steam pressure and pushed to the escape position. At this time, the first exhaust channel is at least partially opened, and the micro-pressure valve structure is opened. The airflow in the cooking chamber flows to the atmosphere, automatically regulating the internal air pressure. By switching the micro-pressure valve structure between the closed and open states, the food processor can improve heating efficiency by increasing the internal pressure of the container without increasing additional heating power, shortening cooking time, preventing food from sticking to the bottom, improving food quality and taste, reducing energy consumption, and improving the user experience.
