Problems solved by technology

[0002] Most of the disinfection cupboards in the prior art use quartz tubes for high-temperature disinfection or drying. When the quartz tubes are heated, their surface temperature can reach more than 800 degrees. The quartz tube is far away from the cabinet door (or other dead angle positions), and its heat radiation area is small, resulting in a very long disinfection or drying process, and the temperature in the cavity is very uneven. The temperature of the utensils close to the quartz tube in the cabinet will be close to that of the quartz tube. temperature, it is easy to damage some tableware made of non-metal (including tableware made of ceramics, glass, wood, plastic, etc.). In addition, during the disinfection process, part of the heat generated by the quartz tube will be dissipated to the air, resulting in a reduction in its energy efficiency
[0003] Furthermore, since there is no air circulation system in the cabinet, it takes a very long time for the quartz tube to uniformly heat the temperature in the cabinet to 100-120 degrees (usually 1-2 hours for each disinfection), and the quartz tube is in a dry state for a long time very easily damaged

no. 1 example

[0031] see Figure 1-Figure 4 , the three-dimensional heating and disinfection cupboard based on thick film heating, including a cabinet body 1 provided with a disinfection chamber 11, a cabinet door 2 connected to the cabinet body 1, and several layers of racks 12 are detachably arranged in the disinfection chamber 11 , The bottom of the disinfection chamber 11 is provided with a thick film heating plate, and the thick film heating plate includes a main heating substrate 31 and a main thick film heating circuit 32 printed on its bottom surface. Although the thick film heating plate is located at the bottom of the disinfection chamber 11, due to the structural characteristics of the thick film heating plate, it is determined that it will not have a large amount of heat radiating to the outside of the cabinet body 1. Only bottom-up three-dimensional heating is performed, with fast heating speed, high efficiency and uniform heat, which can effectively shorten the disinfection or...

no. 2 example

[0038] see Figure 5-Figure 8 The main difference between this three-dimensional heating and disinfection cupboard based on thick film heating and the first embodiment is that additional thick film heating plates can be set under some or all of the shelves 12. In this embodiment, the disinfection chamber 11 is detachably provided with upper and lower two-layer shelf 12, and the bottom of the shelf 12 of the upper floor is provided with another thick film heating plate (such as Figure 7 with Figure 8 As shown), the thick-film heating plate includes a secondary heat-conducting substrate 33 and a secondary thick-film heating circuit 34 printed on its bottom surface. When the volume of the disinfection chamber 11 is large or the height is high, a thick-film heating plate is arranged under the shelf 12 to ensure that the overall heating and disinfection process of the disinfection chamber 11 is more uniform and reliable, and is especially suitable for commercial disinfection cup...

no. 3 example

[0043] see Figure 9 The main difference between this three-dimensional heating and disinfection cupboard based on thick film heating and the first embodiment is that a hot air circulation device is provided on the cabinet body 1; The hot-blast duct 41 at the end is provided with a hot-blast circulation fan 42 on the hot-blast duct 41 . The hot air circulation device can draw air from the top of the disinfection chamber 11, and blow air from the bottom of the disinfection chamber 11, so that a bottom-up circulating airflow is formed in the disinfection chamber 11, and the convection in the disinfection chamber 11 is accelerated, so that the temperature in the disinfection chamber 11 More uniform, further improving the high-temperature disinfection and drying effect of the disinfection cupboard.

[0044] Other unmentioned parts are the same as the first embodiment and will not be repeated.

Abstract

The invention discloses a stereo heating disinfection cabinet based on thick film heating. The stereo heating disinfection cabinet comprises a cabinet body with a disinfection chamber, and a cabinet door in opening and closing connection with the cabinet body, and is characterized in that a thick film heating plate is arranged at the bottom of the disinfection chamber; the thick film heating plate comprises a main heat-conducting substrate and a main thick film heating circuit printed on the bottom surface of the main heat-conducting substrate. The thick film heating plate of the stereo heating disinfection cabinet can perform heating in the form of planar heat dissipation and is large in heat radiation area and high in heat radiation diffusion speed; the thick film heating plate can perform stereo heating on the interior space of the cabinet body closed by the corresponding cabinet door on a large area from the bottom to the top, and is high in heating speed and high in efficiency; the disinfection cabinet is good in high-temperature disinfecting effect and drying effect and high in energy efficiency.
