Description

Technical Field

[0001] The utility model relates to the technical field of disinfection cabinets, and more specifically to an air guide structure of a disinfection cabinet. Background Art

[0002] Disinfection cabinets, as disinfection equipment, have become widely used electrical appliances in homes, restaurants and other places. Disinfection cabinets generally use ultraviolet rays, high temperature, ozone, far infrared rays and other methods to sterilize and disinfect tableware, kitchen utensils, medical equipment, clothing and other items; existing disinfection cabinets generally include main parts such as an outer shell, an inner cavity, and a cabinet door. Disinfection is performed by arranging a heating element or an ultraviolet lamp and other components in the inner cavity. In order to improve the disinfection or drying efficiency, some disinfection cabinets on the market will be provided with a blowing component to blow the heated hot air or the internal air extracted into the inner cavity of the disinfection cabinet, so that the airflow generated in the inner cavity contacts the tableware to improve the disinfection or drying effect. However, at present, such disinfection cabinets usually only use a fan to directly blow air into the interior through the air inlet opened on the side wall of the inner cavity. The airflow can only enter the inner cavity in a straight line within the range of the air inlet. The flow range of the airflow is relatively limited, and it is difficult to fully contact the tableware in different positions, and the disinfection effect is slightly improved. There are also a few disinfection cabinets that form an airflow guiding structure on the side wall of the inner cavity by stamping to achieve airflow guidance, but the processing difficulty of the structure is angle, and the air guiding performance of the air guiding structure formed by processing is relatively limited, which cannot meet the use requirements.

[0027] A wind guide structure for a disinfection cabinet, see Figure 1-3 , including a cabinet 100 and at least one inner cavity 110 in the cabinet 100, such as Figure 1The disinfection cabinet shown has two inner chambers 110. The present embodiment is described with reference to the upper inner chamber 110, the lower inner chamber 110 can be omitted, and the lower inner chamber 110 can have the same structure and configuration as the upper inner chamber 110. The cabinet body 100 can also be provided with only one inner chamber 110 or with more than two inner chambers 110. The cabinet body 100 is the outer shell of the entire disinfection cabinet. The inner chamber 110 is arranged in the cabinet body 100 and can accommodate tableware that needs to be disinfected and sterilized. Usually, the inner chamber 110 has five surfaces: upper, lower, left, right, and rear, and the front side is an open structure. The cabinet body 100 is provided with at least one storage rack 130 embedded in the inner chamber 110. In the present embodiment, the inner chamber 110 above the disinfection cabinet is provided with two storage racks 130. The storage rack 130 in this embodiment specifically refers to the storage rack 130 at the bottom. The storage rack 130 is provided with a cabinet door on the front side. The storage rack 130 can seal the front side of the inner cavity 110 through the cabinet door. The arrangement of the storage rack 130 is convenient for placing different tableware in layers for disinfection; a hot air circulation component 200 is provided on the rear side of the inner cavity 110. The inner cavity 110 is provided with an air outlet 111 and an air inlet 112 respectively connected to both ends of the hot air circulation component 200. The air outlet 111 and the air inlet 112 are openings opened on the rear side wall of the inner cavity 110. The hot air circulation component 200 can draw out the air in the inner cavity 110 from the air outlet 111 and then blow it into the air inlet 112, so as to realize the circulation of air in the inner cavity 110; the inner cavity 110 is provided with a hot air circulation component 200. An air guide cover 120 is provided corresponding to the air inlet 112. The cross-section of the air guide cover 120 is a trapezoidal structure, including a rectangular front side 121 and four oblique side surfaces 122 respectively connected to the four sides of the front side 121 and inclined outwardly. A plurality of air guide holes 101 are respectively provided on the front side 121 and the oblique side surfaces 122. The hot air is guided by the air guide cover 120 to flow into the inner cavity 110 from multiple directions; the air guide cover 130 protrudes into the inner cavity 110. When the hot air circulation component 200 blows air into the inner cavity 110 from the air inlet 112, the air flow is guided by the guide cover 130 and then enters the inner cavity 110 from multiple directions. The air flow passing through the air guide holes 101 on the front side 121 is blown forward, while the air flow passing through the air guide holes 101 on the four oblique side surfaces 122 is obliquely blown out. The airflow is blown outward to diffuse and blow outward, and the airflow has a larger range and is evenly blown to different positions in the inner cavity 110. The tableware in the inner cavity 110 can be more effectively disinfected and dried after being blown by the heated airflow, thereby improving the efficiency and effect of disinfection and drying. The storage rack 130 is provided with a plurality of ventilation holes 131 on the rear side corresponding to the air guide cover 120, so that the airflow passing through the air guide cover 130 can be blown from the ventilation holes 131 into the storage rack 130, and the airflow can be blown to the tableware at the back of the storage rack 130, ensuring that the tableware at different positions can be better contacted by the airflow. At the same time, when the hot air circulates, the air can also pass through the ventilation holes 131 on both sides of the storage rack 130, so that multiple storage racks 130 can all perform hot air circulation.

[0028] Furthermore, the hot air circulation component 200 includes a fan 210 and an air duct 220. The fan 210 is connected to the air outlet 111. The air duct 220 can be a cover structure or a pipeline structure. The air duct 220 in this embodiment is a cover structure, which is sealed and connected to the rear side wall of the inner cavity 110 to form a channel through both sides. The two ends of the air duct 220 are respectively connected to the fan 210 and the air inlet 112. The fan 210 draws out the air in the inner cavity 110 through the air outlet 111 and guides it to the air inlet 112 through the air duct 220. 12 enters the inner cavity 110, and a heating element 221 for heating is provided in the air duct 220. The heating element 221 can heat the air flowing through the air duct 220 to increase the temperature of the air blown into the inner cavity 110 and improve the disinfection effect; a heating tube 113 is provided inside and outside the inner cavity 110, and the heat generated by the heating tube 113 can heat the inner cavity 110 to perform high-temperature disinfection on the tableware inside. In other embodiments, the heating tube 113 can be arranged inside the inner cavity 110 to increase the heating Temperature, and no heating element may be provided in the air duct 220. If the power of the heating tube 113 is high enough to keep the temperature in the inner cavity 110 at the proper temperature, the airflow circulating through the hot air circulation component 200 can still maintain a high temperature, and hot air circulation can also be achieved. The hot air is guided and diffused into the inner cavity 110 after passing through the air guide cover 120, and can also be blown inward through the ventilation holes 131 on the storage rack 130, ensuring that the tableware at different positions in the inner cavity 110 can be efficiently sterilized at high temperature; The air in the cavity 110 is drawn out by the fan through the air outlet 111, heated by the heating element 221 in the air duct 220, and then enters it from the air inlet 112. The air guide cover 120 evenly transports the hot air to the inner cavity 110, and then is reflected by the wall of the storage rack 130 to the front door panel, the inner cavity side wall, and the side wall of the storage rack 130 to reach the air outlet 111, forming an air circulation. The air inlet 112, the air duct 220, the air outlet 111, the air guide cover 120, and the storage rack 130 are combined to form a circulation system.

[0029] Furthermore, the air guide holes 101 include a circular first air guide hole 123 arranged on the front side 121, and a strip-shaped second air guide hole 124 arranged on the oblique side 122. The front side 121 of the air guide cover 120 is a vertical structure. The first air guide holes 123 are evenly distributed on the front side 121. The first air guide holes 123 are a circular structure. The front side plate 121 with a vertical structure can ensure that the blown air flow can be blown outward from the front and enter the storage rack 130 from the ventilation holes 131 at the corresponding positions on the front; the second air guide holes 124 are a strip structure. The strip structure can increase the flow rate of the air flow and blow it out obliquely so that the hot air can be blown into the inner cavity 110 over a larger range. The two opposite ones of the four oblique side surfaces 122 have the same inclination angle, so that the vertical air flow is more balanced. The air guide cover 120 with oblique side surfaces with different inclination angles can be used in conjunction with disinfection cabinets with inner cavities 110 of different sizes to ensure the air guiding effect.

[0030] Furthermore, the air guide cover 120 is provided with an outer edge portion 125 for connecting the side wall of the inner cavity 110, and the outer edge portion 125 extends vertically outward from the outer side of the oblique side surface 122. The air guide cover 120 is formed integrally with the oblique side surface 122 and the outer edge portion 125 by a bending process during production. The outer edge portion 125 is provided with a mounting hole, and the air guide cover 120 is fixed to the rear side wall of the inner cavity 110 by pins or landing on the mounting hole, and the same side wall is stamped on the side wall of the inner cavity 110. The wind guide structure and the wind guide cover 120 are easy to produce and install; an exhaust pipe 114 connected to the outside is provided on the side of the inner cavity 110, and the exhaust pipe 114 can discharge excess air out of the inner cavity 110 to avoid excessive air pressure in the inner cavity 110; an air outlet cover 115 is provided at the air outlet 111 on the inner cavity 110, and the air outlet cover 115 is installed on the rear side wall of the inner cavity 110 at a position corresponding to the air outlet 111 by pins or screws, so as to protect and block the fan 210.

[0031] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
