Abstract
Description
Technical Field
[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processor. Background Technology
[0002] Most food processors, such as juicers and fruit and vegetable juicers, currently use mechanical principles such as squeezing, blade cutting, and impact to press and extract ingredients.
[0003] During the food preparation process, the food comes into direct contact with air and water. The oxygen in the air and water will react with the food (especially fruits and vegetables) to cause oxidation and browning in easily oxidized foods, affecting the taste and appearance of the food. Utility Model Content
[0004] The technical problem to be solved by this invention is to provide a food processor that reduces the risk of food oxidation, in light of the current state of the technology.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a food processor, comprising:
[0006] The cooking pot has a hollow interior forming a cavity;
[0007] The food preparation component is located within the cavity and can move under the drive of the drive mechanism to prepare the food within the cavity.
[0008] Its features are:
[0009] The lower part of the chamber is provided with an air inlet and a switch for opening and closing the air inlet, and the upper part of the chamber is provided with an exhaust outlet.
[0010] The food processor also includes:
[0011] A gas device for generating or storing food preservation gases, wherein the output end of the gas device is connected to the air inlet of the chamber.
[0012] Because the air inlet of this invention is located in the lower part of the chamber, when liquid accumulates in the lower part of the chamber, the food preservation gas enters through the air inlet and drives away the oxygen in the liquid, reducing the oxygen content. The displaced oxygen can then be discharged through the exhaust port in the upper part of the chamber. When the chamber is empty of liquid, the food preservation gas enters through the air inlet and gradually fills the lower part of the chamber, forcing the air in the upper part of the chamber to be discharged through the exhaust port, thus creating a displacement effect. Therefore, this invention replaces both the oxygen in the liquid and the oxygen in the air within the chamber with food preservation gas, achieving both water deoxygenation and chamber deoxygenation functions through the same gas device, reducing the risk of food oxidation.
[0013] The aforementioned food preparation component can be an existing blade, which rotates under the drive of a drive mechanism to break down the food inside the cavity; the food preparation component can also be an existing stirring head, which moves under the drive of a drive mechanism to stir the food inside the cavity, etc.
[0014] The aforementioned food preservation gases can be carbon dioxide, nitrogen, etc.
[0015] Preferably, the gas device is a nitrogen device for generating or storing nitrogen gas, such as existing nitrogen cylinders or nitrogen generators.
[0016] Furthermore, the switch is a one-way valve that allows only gas to pass through, to prevent water from entering the nitrogen unit through the inlet. The aforementioned one-way valve can utilize existing microporous membranes, allowing gas to pass through while preventing liquids from passing.
[0017] Preferably, it also includes a water inlet pipe, with its inlet end connected to an external water source and its outlet end connected to the chamber. That is, an external water source can enter the chamber, and the oxygen in the water can be replaced by introducing food preservation gas.
[0018] Preferably, the outlet end of the water inlet pipe opens at the top of the chamber.
[0019] Preferably, the device also includes a three-way valve, with its first inlet connected to the output end of the gas device, its second inlet connected to the outlet end of the water inlet pipe, and its outlet connected to the air inlet of the chamber. By controlling the three-way valve, water and / or food preservation gas can both enter the chamber through the air inlet.
[0020] Preferably, an air pump is provided on the connecting pipeline between the first inlet of the three-way valve and the output end of the gas device, and a water pump is provided on the water inlet pipe.
[0021] Furthermore, the air inlet is located upwards on the bottom wall of the chamber. Even when there is only a small amount of water in the chamber, food preservation gas can be introduced to deoxygenate the water.
[0022] In the above-mentioned solutions, preferably, the following further includes:
[0023] A detection module for detecting oxygen concentration is located at the exhaust port of the chamber;
[0024] The controller is connected to the detection module and the drive mechanism and is used to control the operation of the drive mechanism.
[0025] This allows the operation of the drive mechanism to be controlled based on the oxygen content within the chamber.
[0026] Preferably, the food processor is a built-in food processor that is embedded in a cabinet. Alternatively, the food processor can also be a countertop unit placed on a kitchen countertop.
[0027] Compared with existing technologies, the advantages of this invention are as follows: Since the air inlet is located at the bottom of the chamber, when liquid accumulates in the lower part of the chamber, the food-preserving gas enters through the air inlet and drives away the oxygen in the liquid, reducing its oxygen content. The displaced oxygen can then be discharged through the exhaust port at the top of the chamber. When the chamber is empty of liquid, the food-preserving gas enters through the air inlet and gradually fills the lower part of the chamber, forcing the air in the upper part of the chamber to be discharged through the exhaust port, thus creating a displacement effect. Therefore, in this invention, both the oxygen in the liquid and the oxygen in the air within the chamber are replaced by the food-preserving gas. This achieves both water deoxygenation and chamber deoxygenation functions through the same gas device, reducing the risk of food oxidation. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0038] Example 1:
[0039] like Figures 1-5As shown, this is a preferred embodiment of the food processor of the present invention. The food processor is an embedded structure for installation in a cabinet, including a shell 7, a cooking pot 1, a cooking component 2, a drive mechanism 3, a water inlet pipe 4, a gas device 5, a detection module 6, and a controller.
[0040] The cooking pot 1 is housed within the outer casing 7 and includes a hollow pot body 1a with an open top, and a lid 1b covering the top of the pot body 1a. The lid 1b and the pot body 1a together define a chamber 10. When the lid 1b is open, ingredients can be added; when the lid 1b is closed, the ingredients can be cooked. In this embodiment, the structure of the lid 1b and the pot body 1a is based on existing technology and will not be described in detail here. The lid 1b in this embodiment is provided with a vent 11, and a valve that can open or close the vent 11 can be installed at the vent 11. The bottom wall of the pot body 1a is provided with an air inlet 12 and a switch 13 for opening and closing the air inlet 12. This switch 13 is a conventional one-way valve that only allows gas to pass through.
[0041] The aforementioned food preparation component 2 is located at the lower part of the chamber 10 and can move under the drive of the drive mechanism 3 to prepare the food within the chamber 10. In this embodiment, as... Figure 3 As shown, the cooking component 2 is a blade located at the lower part of the chamber 10, and the driving mechanism 3 is a motor located below the cooking pot 1. The motor shaft extends upward and is constrained between the motor and the blade to drive the blade to rotate.
[0042] The gas device 5 is an existing nitrogen device for generating or storing nitrogen. The gas device 5 can be located inside or outside the housing 7. The output end of the gas device 5 is connected to the air inlet 12 of the chamber 10, and a gas pump 51 for pumping gas into the chamber is provided on the connecting pipeline.
[0043] like Figure 3 As shown, the inlet end 4a of the aforementioned water inlet pipe 4 is connected to an external water source, and the outlet end 4b faces downwards and extends into the chamber 10 through the pot lid 1b (in addition, the outlet end 4b of the water inlet pipe 4 can also extend into the chamber 10 through the side wall of the pot body 1a; please refer to [link to relevant documentation] for details). Figure 5 Furthermore, the inlet pipe 4 is equipped with a water pump 41 for pumping water into the chamber.
[0044] The aforementioned detection module 6 is a sensor for detecting oxygen concentration, located at the exhaust port 11 of chamber 10. The controller is connected to the detection module 6 and the drive mechanism 3, and controls the operation of the drive mechanism 3 based on the signal output from the detection module. For example, when the oxygen concentration detected by the detection module 6 is lower than a preset value, the drive mechanism 3 drives the food preparation component 2 to process the ingredients.
[0045] The food processor of this embodiment can operate according to the type of food to be processed. For example, when making soy milk, only water can be introduced without nitrogen; when purging chamber 10, only nitrogen can be introduced without water (nitrogen is gradually filled from the bottom of chamber 10, forcing the air in the upper part to be discharged from the exhaust port 11, forming a displacement); when making easily oxidized fruit and vegetable juice, water can be introduced into chamber 10 first, and then nitrogen can be introduced to deoxygenate the water and the upper space of chamber 10.
[0046] Furthermore, in this embodiment, water and nitrogen are introduced independently, allowing for simultaneous water and nitrogen intake, which simplifies control.
[0047] Example 2:
[0048] like Figures 6-9 The image shows a preferred embodiment of the food processor of this utility model. This embodiment is basically the same as the first embodiment, except that it also includes a three-way valve 8. The first inlet of the three-way valve 8 is connected to the output end of the gas device 5, and an air pump 51 is installed on the air inlet pipe connecting the two. The second inlet of the three-way valve 8 is connected to the outlet end 4b of the water inlet pipe 4, and the outlet of the three-way valve 8 is connected to the air inlet 12 of the chamber 10. The three-way valve 8 enables the switching between nitrogen inlet and water inlet states in the chamber, and the water inlet and nitrogen inlet share a single pipe, reducing the number of openings in the chamber. For example, when deoxygenating water, the three-way valve is first controlled to connect to the water inlet pipe 4 to introduce the water needed for processing into the chamber 10. After the water inlet is finished, the three-way valve is controlled to connect to the air inlet pipe to introduce nitrogen into the water to remove oxygen.
