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, and the upper part of the cavity is provided with an exhaust vent;

[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 characteristic is that it also includes:

[0009] Gas devices used to generate or store gases for food preservation;

[0010] A water tank is located outside the chamber, and the water tank has an inlet for external water input and an outlet for water output, the outlet being connected to the chamber; at the same time, the lower part of the water tank has an air inlet connected to the output end of the gas device, and the upper part of the water tank has an air outlet connected to the chamber.

[0011] This invention allows for water deoxygenation before water enters the chamber. Specifically, after water is introduced into the tank, food preservation gas is passed through to displace the oxygen in the water, reducing its oxygen content. The deoxygenated water is then introduced into the chamber. When deoxygenation of the air within the chamber is required, the food preservation gas is passed through a waterless tank before being introduced into the chamber. Therefore, this invention replaces oxygen in both the water and the chamber with food preservation gas, achieving both water deoxygenation and chamber deoxygenation through the same gas device, thus reducing the risk of food oxidation.

[0012] 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.

[0013] The aforementioned food preservation gases can be carbon dioxide, nitrogen, etc.

[0014] Preferably, the gas device is a nitrogen device for generating or storing nitrogen gas, such as existing nitrogen cylinders or nitrogen generators.

[0015] Preferably, the water tank is provided with a switch for opening and closing the air inlet.

[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, an air intake pump is provided on the air intake pipeline between the output end of the gas device and the air intake port of the water tank.

[0018] Preferably, a valve for opening or closing the pipeline is provided on the connecting pipe between the air outlet and the chamber.

[0019] Furthermore, a gas inlet is provided at the lower part of the chamber, and the gas inlet is connected to the vent. That is, the food preservation gas output from the vent enters the chamber through the gas inlet. Since the gas inlet is located at the lower part of the chamber, the food preservation gas input through the gas inlet can enter the liquid in the chamber to deoxygenate the liquid, and at the same time deoxygenate the air above the liquid. The oxygen displaced is discharged outside the chamber through the vent.

[0020] Furthermore, the water inlet is located at the upper part of the water tank, the water outlet is located at the lower part of the water tank, a water pump is provided on the connecting pipeline between the water outlet and the chamber, and a water pump is provided on the water inlet pipeline connected to the water inlet of the water tank.

[0021] In the above-mentioned solutions, preferably, the following further includes:

[0022] A detection module for detecting oxygen concentration is located at the exhaust port of the chamber;

[0023] The controller is connected to the detection module and the drive mechanism and is used to control the operation of the drive mechanism.

[0024] This allows the operation of the drive mechanism to be controlled based on the oxygen content within the chamber.

[0025] 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.

[0026] Compared with existing technologies, the advantages of this invention are as follows: This invention can deoxygenate the water before water enters the chamber. Specifically, after water enters the water tank, food preservation gas is introduced into the water tank to drive away the oxygen in the water, reducing the oxygen content. Then, the deoxygenated water is introduced into the chamber. When it is necessary to deoxygenate the air in the chamber, the food preservation gas can be introduced into a waterless tank, and then introduced into the chamber. Therefore, this invention uses food preservation gas to replace oxygen in both the water and the chamber, achieving both water deoxygenation and chamber deoxygenation functions through the same gas device, reducing the risk of food oxidation.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] like Figures 1-5 As shown, this is a preferred embodiment of a 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 tank 4, a gas device 5, a detection module 6, and a controller.

[0034] 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. Additionally, 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.

[0035] 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 , 4 As shown, the cooking component 2 is a blade located at the lower part of the chamber 10, and the driving mechanism 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.

[0036] The gas device 5 is an existing nitrogen device for generating or storing nitrogen. The gas device 5 may be located inside or outside the housing 7.

[0037] The water tank 4 is located inside the outer shell 7 and outside the chamber 10. The upper part of the water tank 4 has a water inlet 41 for external water input. A water inlet pump 48 is installed on the water inlet pipe connected to the water inlet 41 to pump water into the water tank. The lower part of the water tank 4 has a water outlet 42 for water output. The water outlet 42 is connected to the chamber 10, and a water outlet pump 47 is installed on the connecting pipe. Simultaneously, the bottom of the water tank 4 has an air inlet 43, which is connected to the output end of the gas device 5 via an air inlet pipe. An air inlet pump 51 is installed on the air inlet pipe to pump gas into the water tank 4. A switch 45 for opening and closing the air inlet 43 is provided at the air inlet 43; this switch 45 is a one-way valve that allows only gas to pass through. The top of the water tank 4 has a vent 44, which is connected to the gas inlet 12 at the bottom of the chamber 10. A valve 46 for opening or closing the pipeline is provided on the connecting pipeline. The valve 46 is an existing solenoid valve.

[0038] 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.

[0039] The food processor of this embodiment can operate according to the type of ingredients 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 gradually fills 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 soy milk under pressure, both water and nitrogen can be introduced. First, water in the water tank is transported into chamber 10, and then nitrogen is transported into chamber 10 (at this time, the exhaust port 11 is in a closed state). When making easily oxidized fruit and vegetable juice, water can be introduced into the water tank first, and then nitrogen can be introduced to deoxygenate the water, and the deoxygenated water is introduced into the chamber.
