Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum cooling technology, and more specifically, to a vacuum cooling device. Background Technology
[0002] Vacuum cooling devices are food cooling equipment that utilizes a vacuum environment to reduce air pressure, allowing moisture to evaporate rapidly at low temperatures. By lowering the boiling point through vacuuming, the moisture in the material quickly vaporizes and absorbs heat, achieving efficient cooling. This device is suitable for cooked foods, vegetables, etc., and can reduce the temperature from high temperatures to a safe range in a short time, maintaining food quality, reducing bacterial growth, and is widely used in the food processing and catering industries.
[0003] In existing vacuum cooling devices, the suction pipe is connected to the cabinet via a flange. However, due to the frequent temperature changes and mechanical vibrations that the flange is subjected to over a long period of time, the sealing gasket is prone to aging and deformation, resulting in tiny air leaks at the connection. These leaks are difficult to detect with the naked eye, but they will seriously affect the vacuum level, reduce suction efficiency, prolong cooling time, and even affect the food preservation effect. If not dealt with in time, they will also increase energy consumption and reduce equipment stability.
[0004] In summary, to ensure the efficient and stable operation of the vacuum cooling device, it is necessary to address the problem of micro-leakage at the flange connection caused by long-term use, which is difficult to detect. This will ensure that the vacuuming effect is always kept at its optimal level, thereby improving cooling efficiency, reducing energy consumption, and protecting food quality and safety. Utility Model Content
[0005] The present invention provides a vacuum cooling device that aims to solve the following problem: In existing vacuum cooling devices, the air extraction pipe is connected to the cabinet through a flange. After long-term use, the flange is prone to air leakage, which is difficult to detect with the naked eye, resulting in an unsatisfactory vacuuming effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a vacuum cooling device, including a cooling cabinet, a sealing door rotatably connected to the front side of the cooling cabinet, a vacuum module installed on the left side of the cooling cabinet, multiple suction pipes provided on the vacuum module, the suction pipes being connected to the cooling cabinet via flanges, a fixing plate fixed to the top of the cooling cabinet outside the suction pipes, a mounting shell provided on the top of the fixing plate, a guide rail installed inside the mounting shell, a rotating ring slidably connected to the inner side of the guide rail, a mounting ring fixed to the top of the rotating ring, several blades installed on the top of the mounting ring, a sealing cover fixed to the mounting shell, the sealing cover being sealed to the suction pipes, a wiping mechanism provided on the sealing door, and a condensation mechanism provided inside the cooling cabinet.
[0007] In a preferred embodiment, the wiping mechanism includes a scraping component and a driving component. The scraping component is used to wipe away water mist on the observation window of the sealed door, and the driving component is used to drive the scraping component to rotate.
[0008] In a preferred embodiment, the scraping assembly includes a drive shaft that is rotatably connected to a sealed door, with a scraper fixed to the rear end of the drive shaft, the scraper fitting against the observation window of the sealed door.
[0009] In a preferred embodiment, the drive assembly includes a driven gear fixed to the front end of the drive shaft, a drive motor fixed to the front side of the sealing door, and a drive gear installed at the output end of the drive motor, the drive gear meshing with the driven gear.
[0010] In a preferred embodiment, the condensation mechanism includes a flow guiding component and a collection component, wherein the flow guiding component is used to guide the flow direction of the condensate, and the collection component is used to collect the condensate.
[0011] In a preferred embodiment, the drainage assembly includes multiple columns fixed to the top surface inside the cooling cabinet, with condensation plates installed at the bottom of the columns in a herringbone shape.
[0012] In a preferred embodiment, the collection component includes two mounting bases fixed to the bottom surface inside the cooling cabinet, each mounting base having a collection groove.
[0013] The beneficial effects of this utility model are as follows: This invention significantly improves the sealing monitoring efficiency of the vacuum cooling device by adding a blade detection mechanism at the flange connection. When the flange experiences micro-leakage due to aging or vibration, the airflow drives the blades to rotate, transforming the previously difficult-to-detect leakage into a visible mechanical movement. This design not only enables real-time visual monitoring of leaks but also greatly reduces the difficulty of manual inspections, effectively preventing problems such as decreased vacuum and reduced cooling efficiency caused by leaks. Furthermore, this structure requires no additional power supply or complex sensors, is simple to maintain, highly reliable, and can promptly detect early leakage risks, ensuring long-term stable operation of the equipment, extending its service life, and reducing maintenance costs.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0021] Refer to the instruction manual appendix Figures 1 to 5 A vacuum cooling device includes a cooling cabinet 1, a sealing door 2 rotatably connected to the front of the cooling cabinet 1, a vacuum module 3 installed on the left side of the cooling cabinet 1, a plurality of suction pipes 4 provided on the vacuum module 3, the suction pipes 4 being connected to the cooling cabinet 1 via flanges, a fixing plate 5 fixed on the top of the cooling cabinet 1 outside the suction pipes 4, a mounting shell 6 provided on the top of the fixing plate 5, a guide rail 7 installed inside the mounting shell 6, a rotating ring 8 slidably connected to the inner side of the guide rail 7, a mounting ring 9 fixed on the top of the rotating ring 8, a plurality of blades 10 installed on the top of the mounting ring 9, a sealing cover 11 fixed on the mounting shell 6, the sealing cover 11 being sealed to the suction pipes 4, a wiping mechanism provided on the sealing door 2, and a condensation mechanism provided inside the cooling cabinet 1.
[0022] It should be noted that the mounting shell 6 is made of transparent acrylic sheet. Its transparency allows staff to directly observe the movement of the blade 10. When there is an air leak at the flange connecting the suction pipe 4 and the cooling cabinet 1, the airflow blows the blade 10, causing the mounting ring 9 to drive the rotating ring 8 to rotate under the restriction of the guide rail 7. Ball bearings can be added to the inside of the guide rail 7 to improve sensitivity.
[0023] Refer to the instruction manual appendix Figure 2 and Figure 4 The wiping mechanism includes a scraping component and a driving component. The scraping component is used to wipe away water mist on the observation window of the sealed door 2, and the driving component is used to drive the scraping component to rotate.
[0024] It should be noted that when the drive component is in operation, it can drive the scraping component to rotate, thereby wiping away the water mist on the observation window of the sealed door 2.
[0025] Refer to the instruction manual appendix Figure 2 and Figure 4 The scraping assembly includes a drive shaft 121 that is rotatably connected to the sealed door 2. A scraper 122 is fixed to the rear end of the drive shaft 121 and fits against the observation window of the sealed door 2.
[0026] It should be noted that when the drive shaft 121 rotates, it drives the scraper 122 to rotate, and the scraper 122 wipes the water mist.
[0027] Refer to the instruction manual appendix Figure 4 The drive assembly includes a driven gear 123 fixed to the front end of the drive shaft 121, a drive motor 124 fixed to the front side of the sealing door 2, and a drive gear 125 installed at the output end of the drive motor 124. The drive gear 125 meshes with the driven gear 123.
[0028] It should be noted that when the drive motor 124 is in operation, it drives the drive gear 125 to rotate. The drive gear 125 meshes with the driven gear 123 to drive the transmission shaft 121 to rotate.
[0029] Refer to the instruction manual appendix Figure 2 The condensation mechanism includes a flow guiding component and a collection component. The flow guiding component is used to guide the flow direction of the condensate, and the collection component is used to collect the condensate.
[0030] It should be noted that hot air condenses on the drainage component, and water droplets slide down the condensation component and fall into the collection component.
[0031] Refer to the instruction manual appendix Figure 2 The flow diversion assembly includes multiple columns 131 fixed inside the top surface of the cooling cabinet 1, and a condenser plate 132 is installed at the bottom of the column 131. The condenser plate 132 is in the shape of a herringbone.
[0032] It should be noted that when hot air comes into contact with the condenser plate 132, it will condense into water droplets on the condenser plate 132. Due to the herringbone structure of the condenser plate 132, the water droplets will slide down to both sides of the condenser plate 132 and will not drip onto the cooled food.
[0033] Refer to the instruction manual appendix Figure 2 The collection component includes two fixed seats 133 fixed to the bottom surface inside the cooling cabinet 1, and each of the two fixed seats 133 is provided with a collection groove 134.
[0034] It should be noted that water droplets dripping down the condenser plate 132 will fall into the collection tank 134, making it easy to clean them all at once.
[0035] Working principle: After the vacuum module 3 is started, it draws a vacuum inside the cooling cabinet 1 through the suction pipe 4 to form a low-pressure environment. If a leak occurs at the flange connecting the suction pipe 4 and the cooling cabinet 1, the airflow will blow the blade 10 on the top of the mounting ring 9, causing the mounting ring 9 and the rotating ring 8 to rotate along the guide rail 7. The staff can directly observe the rotation of the blade 10 through the transparent acrylic mounting shell 6, thereby identifying the leak. At the same time, when the hot steam from the food in the cooling cabinet 1 generates water mist in the observation window of the sealed door 2, the drive motor 124 meshes with the driven gear 123 through the drive gear 125, driving the scraper 122 at the end of the transmission shaft 121 to rotate and wipe away the water mist. The hot steam in the cooling cabinet 1 condenses into water droplets after contacting the herringbone condenser plate 132, and slides down the inclined plate surface to both sides into the collection tank 134 of the fixed seat 133 for unified collection, avoiding water droplet contamination of the food.
[0036] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
