Description

Technical Field

[0001] The invention belongs to the technical field of refrigerators, and in particular relates to an intelligent ventilation device for a refrigerator. Background Art

[0002] A freezer, also called a refrigerator, is a device that preserves food and other items at low temperatures. There are two types of freezers: home and commercial. Commercial freezers are used in restaurants, bars, food processing, and supermarkets. In the announcement number CN204254963U, a ventilation device for a freezer is disclosed. The device uses a mechanical structure to achieve internal and external air pressure balance to facilitate the opening and closing of the cabinet door. However, the patent does not use any intelligent structure to achieve and detect the balance of internal and external gases. In actual applications, there are still certain errors. In addition, the ventilation device of the above patent has a relatively single function. In addition to the function of balancing the internal and external air pressure, it has no other functions, so there is room for improvement. Summary of the invention

[0003] The object of the present invention is to provide an intelligent ventilation device for a refrigerator to solve the problem that the existing ventilation devices mentioned in the above background technology have single functions and low intelligence.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an intelligent ventilation device for a refrigerator, comprising a connecting pipe, which is built into the door of the refrigerator, and the connecting pipe is composed of two sections, a pipe one and a pipe two; a mounting plate, which is installed on the top of the pipe two and fits on the inner side of the refrigerator door, and an intelligent control component is installed inside the mounting plate; a suction pump, which has two ports and is respectively connected to the top of the pipe one and the bottom of the pipe two, and the suction pump connects the pipe one and the pipe two to form an air inlet and outlet channel, and the suction pump is connected to the intelligent control component, and according to the instructions issued by the intelligent control component, the air pressure inside and outside the refrigerator is regulated, and the odorous gas inside the refrigerator is discharged.

[0005] As a preferred technical solution in the present invention, a corrugated portion 1 is formed in the bottom area of ​​the pipe 1, and a corrugated portion 2 is formed in the top area of ​​the pipe 2. The corrugated portion 2 does not contact the mounting plate. In the early installation, the lengths of the pipe 1 and the pipe 2 can be adjusted according to the characteristics of the corrugated portion 1 and the corrugated portion 2 to achieve the adjustment of refrigerator doors of different specifications.

[0006] As a preferred technical solution in the present invention, an area on the surface of the mounting plate bulges backward and forms a placement portion with a placement cavity. The intelligent control component is placed in the placement portion to facilitate the installation and unified management of the intelligent control component. The intelligent control component includes a wireless terminal installed at the top of the placement portion. The wireless terminal has a built-in detachable power supply. A connecting plate is also provided at the bottom of the wireless terminal. A plurality of functional sensors are installed on the surface of the connecting plate. The functional sensors are connected to the wireless terminal via wires. During use, the odor inside the refrigerator is detected by the functional sensor. When the odor reaches a threshold, the suction pump can be started to discharge the odor inside the refrigerator.

[0007] As a preferred technical solution in the present invention, the multiple functional sensors include an odor sensor and a distance sensor, wherein the odor sensor is used to detect the odor inside the refrigerator, and the distance sensor can detect the change in distance when the refrigerator door is opened, and start the suction pump to adjust the air pressure inside and outside the refrigerator to ensure that the normal opening and closing of the door is not affected.

[0008] As a preferred technical solution in the present invention, the wireless terminal is also connected to a connecting harness, and the connecting harness is connected to the suction pump. The suction pump is turned on and off by the wireless terminal to control the suction pump. When the odor inside the refrigerator needs to be adjusted or the normal air pressure is discharged outward, the suction pump extracts the gas inside the refrigerator through pipe two and discharges it through pipe one. Conversely, when the external gas needs to be drawn into the refrigerator, the suction pump extracts the gas in the opposite direction through pipe one and then discharges it through pipe two.

[0009] As a preferred technical solution in the present invention, the two sections of the connecting plate are fixed at the inner wall of the placement portion, and a waterproof lithium battery is also arranged between the connecting plate and the bottom end surface inside the placement portion. The waterproof lithium battery is connected to the suction pump through a connecting harness to provide power. It is worth noting here that the connecting harness is not a single wire, but is composed of multiple wires.

[0010] As a preferred technical solution in the present invention, a socket is provided on the side of the placement portion, and a charging interface is provided on the side of the waterproof lithium battery. The charging interface is on the same horizontal line as the waterproof lithium battery. During use, the wire can be passed through the socket and inserted into the waterproof lithium battery for charging.

[0011] As a preferred technical solution in the present invention, a protective plate is also provided on the front surface of the mounting plate. The protective plate is made of transparent acrylic material. The protective plate cover is arranged at the opening position of the placement portion to protect the intelligent control component. A distance is left between the protective plate and the placement portion to facilitate the functional sensor to detect odors in the refrigerator.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Through the design of the present invention, intelligent equipment is used to detect and adjust the balance of internal and external air pressure, thereby avoiding the pressure imbalance phenomenon caused by over-reliance on mechanical structure and ensuring the normal opening of the cabinet door. At the same time, the ventilation device of the present invention can also remove the odor inside the refrigerator according to actual needs to ensure the cleanliness of the interior of the refrigerator. The entire operation is highly intelligent, which improves the shortcomings of the existing device in use. BRIEF DESCRIPTION OF THE DRAWINGS
