Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

Example 1:

as shown in figure 1, a first preferred embodiment of the disinfection cabinet of the present invention is shown. The disinfection cabinet comprises a cabinet body 1, a heating element 2, a supporting plate 3 and an induction device 4 a.

The cabinet body 1 comprises a shell 11 and an inner container 12 arranged in the shell 11, an interlayer 111 is formed between the outer wall of the inner container 12 and the inner wall of the shell 11, and a disinfection cavity 121 is formed inside the inner container 12; a concave part 122 is formed on the bottom plate of the inner container 12 in a downward concave manner, and a through hole 1221 is formed on the bottom wall of the concave part 122; a drawer 123 is installed in the sterilizing chamber 121 to be drawably moved in and out of the sterilizing chamber 121.

The heating member 2 is installed at the rear portion of the bottom wall inside the inner container 12, and the recess 122 is located in front of the heating member 2 and is disposed adjacent to the heating member 2. In this embodiment, heating member 2 establishes the pipe casing in this heating pipe periphery including the heating pipe and the cover that arrange along the length direction of the cabinet body 1, and the pipe casing plays the guard action to the heating pipe, and this is conventional structure, and no longer gives details here, can specifically refer to utility model patent "a safe type sterilizer" that patent application number is CN201521088714.9 (publication number is CN 205339605U).

The support plate 3 is located in the recess 122, and a folded edge 31 is formed by bending the outer edge of the support plate 3 downward, and the folded edge 31 is closely attached to the inner peripheral wall of the recess 122.

The sensing means 4a is mounted in the interlayer 111 below the support plate 3 and acts on the support plate 3 through the through-hole 1221 for monitoring whether the support plate 3 is in an unloaded state. In addition, the disinfection cabinet is provided with a controller, and the heating element 2 and the induction device 4a are electrically connected with the controller, so that the controller can receive signals collected by the induction device 4a and control the heating element 2 to be opened and closed.

In this embodiment, the sensing device 4a includes a mounting seat 40a, an elastic member 41a and a contact switch 42 a. Specifically, the mounting seat 40a is mounted on the bottom plate of the housing 11, and the mounting seat 40a is provided with a mounting groove; the elastic piece 41a is a compression spring, the bottom of the elastic piece 41a is accommodated in the installation groove, the top end of the elastic piece 41a penetrates through the through hole 1221 to abut against the bottom wall of the support plate 3, and the support plate 3 can always have a tendency of moving away from the bottom plate of the shell 11; the contact switch 42a has a contact point;

in the state that the support plate 3 is unloaded, the support plate 3 is separated from the contact of the contact switch 42a under the elastic force of the elastic member 41a to make the contact switch 42a be turned off;

in a state where the support plate 3 carries the dropped tableware, the support plate 3 presses the contact of the contact switch 42a against the elastic force of the elastic member 41a to close the contact switch 42 a.

The working principle of the embodiment is as follows: when the drying program is started, the heating element 2 starts to heat, and at this time, if small tableware such as chopsticks falls on the support plate 3, the elastic element 41a is compressed, the support plate 3 is in contact with the contact of the contact switch 42a, the electric signal is uploaded to the controller, and the controller cuts off the power supply of the heating element 2 to stop heating.

Example 2:

fig. 2 shows a second preferred embodiment of the disinfection cabinet according to the utility model. The difference from example 1 is that:

in this embodiment, the sensing device 4b includes a microgravity sensor 41b and a heat shield 42 b. A microgravity sensor 41b mounted on the bottom plate of the housing 11 for detecting the pressure applied by the support plate 3; the thermal insulation plate 42b is positioned between the support plate 3 and the microgravity sensor 41b to thermally insulate and protect the microgravity sensor 41b, thereby improving the service life of the microgravity sensor 41 b.

The working principle of the embodiment is as follows: and starting a drying program, heating the heating element 2, and at the moment, if small tableware such as chopsticks and the like fall on the supporting plate 3, acquiring a gravity signal by the microgravity sensor 41b and uploading the gravity signal to the controller, and cutting off the power supply of the heating element 2 by the controller to stop heating.

Example 3:

fig. 3 shows a third preferred embodiment of the disinfection cabinet according to the utility model. The difference from example 1 is that:

in this embodiment, the sensing device 4c includes an airbag 41c and a pressure sensor 42 c. The air chamber 411c is provided inside the air bag 41c and is arranged between the support plate 3 and the bottom plate of the housing 11; the air pressure sensor 42c is connected to the outside of the air bag 41c, and communicates with the air chamber 411c to detect the air pressure of the air chamber 411 c. The air bag 41c is protected by a metal shell, which can ensure that the air bag 41c does not expand along the periphery.

Since the temperature of the bottom plate of the inner container 12 is very high, if the sensor of embodiment 2 is directly used, the service life of the sensor is seriously reduced, so that the heat insulation protection is required to improve the service life of the sensor, and the air in the embodiment is a very good heat insulation material.

It should be noted that the inner container 12 is provided with an air outlet (not shown) for communicating the sterilization chamber 121 with the outside atmosphere, so as to heat the air in the sterilization chamber 121, and thus the pressure in the sterilization chamber 121 will not rise, which will cause the pressure change in the air bag 41c and cause a false touch signal.

The working principle of the embodiment is as follows: when the drying program is started, the heating element 2 starts to heat, and if some small tableware such as chopsticks fall off the support plate 3, the pressure value of the air cavity 411c in the air bag 41c changes, the air pressure sensor 42c obtains a signal and uploads the signal to the controller, and the controller cuts off the power supply of the heating element 2 to stop heating.
