[0002] A kitchen cabinet is a piece of furniture installed in the kitchen to store tableware, cookware, food, and various kitchen utensils. The cabinet is generally made of materials such as wood, artificial boards, or metal to provide storage space for items.
[0003] A cabinet with good ventilation is disclosed in publication number CN221356234U. The cabinet includes a cabinet body, a first rotating rod rotatably connected to the lower surface of the cabinet body, and multiple placement plates fixedly sleeved on the rod wall of the first rotating rod. A partition is fixedly connected inside the cabinet body, and two second rotating rods and one third rotating rod are rotatably connected to the lower surface of the partition. A driving mechanism is provided above the partition, and both the second and third rotating rods rotate via the driving mechanism. A transmission mechanism is provided at the upper end of the first rotating rod, and the driving mechanism drives the first rotating rod to rotate via the transmission mechanism. Fan blades are fixedly connected to the rod walls of both second rotating rods. This invention, by using placement plates fixedly sleeved on the rod walls of the first rotating rod, allows each placement plate to rotate by the rotation of the first rotating rod, thus making it easier for users to retrieve tableware from deeper inside the cabinet.
[0004] When the above-mentioned device is in use, it draws in external air through the fan blades and air inlet, blows it into the cabinet, and then circulates through the ventilation holes on the shelf before being discharged through the air outlet. However, when items are placed on the shelf, they will block the ventilation holes, causing the overall air circulation rate to decrease, resulting in poor overall ventilation. Therefore, we propose a cabinet with a ventilation structure. Utility Model Content

[0028] This utility model provides a cabinet with an exhaust structure, which can accelerate the air circulation rate inside the cabinet 100 by suction, thereby improving the overall exhaust effect. It can also filter the air entering the cabinet 100, thus improving the storage effect of items inside the cabinet 100. Please refer to [link / reference]. Figure 1-4 Including cabinet 100;
[0029] Please refer to it again. Figure 1-3The top left and right sides of the cabinet 100 have air cavities 110, which are used to store the air that will enter the cabinet 100. The inner walls of the cabinet 100 have evenly spaced air inlets 111, which are used to distribute air evenly inside the cabinet 100. The inner cavity of the cabinet 100 is connected to the air cavities 110 through the air inlets 111. A damping shaft 112 is fixedly connected to the middle of the top of the cabinet 100. The damping shaft 112 is used to install and allow the hollow rod 113 to rotate, thus facilitating the retrieval of items deep inside. The bottom end of the damping shaft 112 is fixedly connected to the hollow rod 113, which is used for mounting and placing... The outer walls of the hollow rod 113 and the circular disc 115 have air outlets 114 on the front and back sides and the left and right sides. The air outlets 114 are used to extract air. The four air outlets 114 are evenly distributed from top to bottom in a group. The outer walls of the hollow rod 113 are fitted with a placement disc 115 between two adjacent groups of air outlets 114. The placement discs 115 are used to place items and are evenly distributed from top to bottom. The bottom of the cabinet 100 is fixedly connected to the mounting cylinder 116, which is used to install the exhaust fan 117. The bottom end of the hollow rod 113 extends into the inner cavity of the mounting cylinder 116, and the inner wall of the mounting cylinder 116 is fixedly connected to the exhaust fan. 117. The exhaust fan 117 is used to draw air to ventilate the interior of the cabinet 100. The front wall of the cabinet 100 is rotatably connected to the cabinet door 118, which protects the items inside the cabinet 100. A baffle is provided on the inner wall of the mounting cylinder 116 below the exhaust fan 117 to improve safety and prevent contact with the exhaust fan 117. A sealing gasket is provided between the rear wall of the cabinet door 118 and the front wall of the cabinet 100 to improve the sealing between the cabinet door 118 and the cabinet 100. When in use, items are placed on the placement disc 115. When it is necessary to retrieve items deep inside, the damping pivot 112 is used in conjunction with the hollow rod 113. Rotate the placement disc 115 to bring items from the depths to the front for retrieval. During daily use, the exhaust fan 117 is activated via an external controller. The exhaust fan 117, through the hollow rod 113 and the air outlet 114, draws air from inside the cabinet 100, causing air from all parts of the cabinet 100 to converge and flow towards the hollow rod 113. The air then enters the hollow rod 113 through the air outlet 114 and is then discharged to the outside of the cabinet 100 for ventilation. At the same time, fresh air from outside the top of the cabinet 100 is drawn into the air chamber 110 and then flows evenly to all parts of the cabinet 100 through the air inlet 111.
[0030] In summary, the intake method accelerates the air circulation rate within the cabinet 100, thereby improving the overall ventilation effect.
[0031] Please refer to it again. Figure 1 , Figure 2 and Figure 4 A filter box 120 is inserted into the upper side of the inner wall of the air chamber 110. The filter box 120 is used to place silica gel particles and activated carbon particles to filter moisture, odors and dust in the air to improve air quality. The top of the filter box 120 extends to the outside of the air chamber 110. Ventilation holes are evenly distributed at the bottom of the inner wall of the filter box 120 to facilitate air entry. A filter screen 121 is placed on the top of the filter box 120. The filter screen 121 is used to filter larger dust particles and prevent mosquitoes from entering. The filter box 120 has mounting slots 122 on both sides of the top center. The mounting slots 122 are used to install the first magnet 123. The bottom of the inner wall of the mounting slot 122 is fixedly connected to the first magnet 123. The first magnet 123 is used to cooperate with the second magnet 124 to facilitate the installation and removal of the filter screen 121. The top of the first magnet 123 is magnetically connected to the second magnet 124. The second magnet 124 is used to cooperate with the first magnet 123 and the mounting slot 122 to facilitate the installation and removal of the filter screen 121. This facilitates subsequent maintenance. The top of the second magnet 124 extends to the outside of the mounting groove 122 and is fixedly connected to the bottom of the filter screen 121. The upper and lower sides of the inner cavity of the filter box 120 are filled with silica gel particles and activated carbon particles, respectively. The silica gel particles are used to absorb moisture in the air, and the activated carbon particles are used to absorb odors and small dust particles in the air. A rubber gasket is provided between the outer wall of the filter box 120 and the inner wall of the air cavity 110. The rubber gasket is used to improve the sealing between the filter box 120 and the air cavity 110, and at the same time, it uses its own characteristics to fix the filter box 120, making it easy to install and remove the filter box 120. After the filter screen 121 filters out larger dust particles in the air, it enters the filter box 120. When the air enters the filter box 120, it comes into contact with the silica gel particles and activated carbon particles from top to bottom. The silica gel particles absorb the moisture in the air, and the activated carbon particles filter out odors and small dust particles in the air. The filtered air flows into the air cavity 110.
[0032] In summary, the system can filter the air entering the cabinet 100, thereby improving the storage effect of items inside the cabinet 100.
[0033] In practical use, those skilled in the art place items on the placement disc 115. When retrieving items from deeper areas, the damping shaft 112, in conjunction with the hollow rod 113, rotates the placement disc 115 to bring the items to the front for retrieval. During daily use, an external controller activates the exhaust fan 117. The exhaust fan 117, through the hollow rod 113 and air outlet 114, draws air from inside the cabinet 100, causing air to gather and flow towards the hollow rod 113. Air then enters the hollow rod 113 through the air outlet 114 and is exhausted to the outside of the cabinet 100 for ventilation. Simultaneously, fresh air from outside the top of the cabinet 100 is drawn in. The air flows to the filter plate 121, where larger dust particles are filtered before entering the filter box 120. As air enters the filter box 120, it comes into contact with silica gel particles and activated carbon particles from top to bottom. The silica gel particles absorb moisture from the air, while the activated carbon particles filter odors and smaller dust particles. The filtered air flows into the air chamber 110 and then flows evenly throughout the cabinet 100 through the air inlet 111. Maintenance simply requires removing the filter box 120, separating the second magnet 124 from the first magnet 123 to remove the filter plate 121 for cleaning, and replacing the silica gel particles and activated carbon particles inside the filter box 120.
