Description

Technical Field

[0001] The utility model relates to the technical field of disinfection cabinets, in particular to an internal circulation 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 achieve a high temperature and a better disinfection effect, some disinfection cabinets on the market use a high-power heating element to heat the inner cavity. The inner cavity wall or other components close to the heating element in such disinfection cabinets may not be able to withstand the high temperature and be deformed or damaged; the heating element of most disinfection cabinets is arranged in the inner cavity. This type of structure hinders the cleaning of the corresponding position in the inner cavity when the user cleans it, which is inconvenient to clean, and the user may come into contact with the heating element, which poses certain safety hazards; some disinfection cabinets are also provided with air inlet and outlet components to make the air flow in the inner cavity to achieve drying or hot air circulation disinfection effects, but such disinfection cabinets usually extract the internal air or simply extract the air and then blow it in, which is easy to cause the temperature in the inner cavity to drop, which may reduce the disinfection effect and is difficult to meet the use requirements. Utility Model Content

[0003] In view of this, the utility model provides an internal circulation disinfection cabinet.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an internal circulation disinfection cabinet, comprising: an outer shell and at least one inner cavity arranged in the outer shell, the inner cavity is formed by a plurality of inner cavity panels, at least one inner cavity is provided with a first heating element and a hot air circulation component; the inner cavity is provided with an air outlet and an air inlet, and the hot air circulation component defines a hot air circulation channel connecting the air outlet and the air inlet outside the inner cavity; the hot air circulation component comprises: a fan and a second heating element, the fan is installed corresponding to the air outlet or the air inlet, and the second heating element is located in the hot air circulation channel.

[0005] As a preferred solution of the utility model, the hot air circulation component also includes: an air duct shell; the fan has a fan casing and fan blades, the fan casing and the air duct shell are connected and installed on the outer wall of the inner cavity plate to construct the hot air circulation channel; the second heating element is installed in the air duct shell.

[0006] As a preferred solution of the utility model, the first heating element is installed on the outer wall surface of the inner cavity plate, and its heat is transferred to the inside of the inner cavity.

[0007] As a preferred solution of the utility model, the surface of the air duct shell at one end close to the air inlet is provided with an arc surface bending toward the inner cavity.

[0008] As a preferred solution of the utility model, a fixing bracket for fixing the second heating element is provided between the air duct shell and the inner cavity.

[0009] As a preferred solution of the utility model, the fixed bracket is provided with a plurality of slots, the second heating element has a plurality of annular heating tube sections, and the second heating element is fixed to the fixed bracket through the slots.

[0010] As a preferred solution of the utility model, the inner cavity includes: a first inner cavity and a second inner cavity, the first inner cavity is provided with the first heating element and the hot air circulation component; the second inner cavity is located below the first inner cavity, and the first heating element is located between the bottom surface of the first inner cavity and the top surface of the second inner cavity.

[0011] As a preferred solution of the present invention, the first inner cavity is provided with an ultraviolet lamp, and / or the second inner cavity is provided with an ultraviolet lamp.

[0012] It can be seen from the above technical solutions that, compared with the prior art, the present invention has the following beneficial technical effects:

[0013] During disinfection, the air in the inner cavity is drawn out by the fan and flows in the direction of the air duct shell, that is, it flows into the hot air circulation duct. The air passing through the second heating element on the way is heated and then enters the inner cavity through the air inlet, and then is reflected by the wall of the storage rack to the front door panel, the inner cavity side wall, the storage rack side wall, and reaches the air outlet to form an air circulation. The air inlet, air duct, air outlet, air guide cover, and storage rack are combined to form a circulation system to maintain the temperature in the inner cavity and improve the heating and disinfection effect. The heated airflow flows in the inner cavity, making the internal heat more uniform, ensuring that tableware placed in different positions can be fully heated to achieve high-temperature disinfection; the first heating element and the second heating element fixed on the outer wall of the inner cavity plate are heated at the same time, which can also heat the wall of the inner cavity and have a corresponding disinfection effect on the interior. Function: When the same cavity is heated to the same temperature, the coordinated heating structure of the two heating elements can set the power of the single heating element lower than that of the single heating element, avoiding excessive power of the single heating element, which causes the adjacent inner cavity wall to be unable to withstand high temperature and deform or be damaged. The utility model adopts two heating elements to be arranged at different positions, which makes the heating more uniform, and the power of the single heating element is not too high, ensuring that the wall of the inner cavity can withstand the corresponding temperature. The structure of hot air circulation enables the inner cavity to be heated quickly, and the internal temperature can be maintained above 100 degrees as a whole, with good disinfection effect; the first heating element and the second heating element are both arranged outside the first inner cavity, which can ensure that the user will not directly contact them, improve safety, and will not be hindered by the heating elements when cleaning the first inner cavity, so it is easy to clean.
