[0051] The cabinet 1 has a sterilization cavity 11 inside and an opening on the front side, and the front part of the top wall of the cabinet 1 is provided with an exhaust hole 12 corresponding to the exhaust duct 4 described below. The sterilization cavity 11 is generally provided with a heating tube and a sterilization lamp tube as sterilization devices, which is a conventional structure of the sterilizer and will not be described here.

[0052] The number of drawers 2 is two, the upper drawer 2 is referred to as the upper drawer, and the lower drawer 2 is referred to as the lower drawer, and each drawer 2 can be pulled in and out of the sterilization cavity 11 through the opening on the front side of the cabinet 1. Specifically, each drawer 2 comprises a door body 21 and a storage rack 22 mounted on the back of the door body 21, and the inside of the door body 21 has a sandwich layer 211.

[0053] The inner drawer 3 is arranged at the top of the sterilization cavity 11 and can be pulled in and out of the sterilization cavity 11 through the opening on the front side of the cabinet 1, and in the state that the upper drawer is closed, the inner drawer 3 is accommodated at the top of the inner cavity of the upper drawer. Specifically, the left and right sides of the inner drawer 3 are mounted on the top of the sterilization cavity 11 through guide rails 30, the fixed rails of each guide rail 30 are mounted on the inner wall of the cabinet 1 in the front-rear direction, and the movable rails of the guide rail 30 are mounted on the side wall of the inner drawer 3 in the front-rear direction; the front side wall of the inner drawer 3 is detachably mounted with a plugging member 31 for covering the inlet end of the exhaust duct 4 described below, the plugging member 31 has a water collecting groove 311 with an opening at the top inside; a plurality of flow-through holes 32 are formed on the bottom wall of the inner drawer 3.

[0054] The steam exhaust pipe 4 is installed on the back of the door body 21 of the upper drawer, and has an inlet end communicating with the sterilization cavity 11 and an outlet end communicating with the atmosphere. In the embodiment, the steam exhaust pipe 4 extends from the inlet end to the outlet end in a top-down manner, and in the state that the upper drawer is closed, the outlet end of the steam exhaust pipe 4 is opposite to the steam exhaust hole 12; the inlet end of the steam exhaust pipe 4 and the top side edge of the blocking piece 31 are respectively provided with a first inclined surface and a second inclined surface which gradually rise from front to back, and in the state that the second inclined surface abuts against the first inclined surface, the blocking piece 31 covers the inlet end of the steam exhaust pipe 4.

[0055] The driving mechanism 5 comprises a screw rod 51, a sliding block 52 and a driving piece 53. Specifically, the screw rod 51 is installed on the top wall of the sterilization cavity 11 and extends in the front-rear direction; the sliding block 52 is installed on the rear side of the inner drawer 3 and is threadedly connected to the outer periphery of the screw rod 51; and the driving piece 53 is an electric motor, and the power output end thereof is connected to the rear end of the screw rod 51 to drive the screw rod 51 to rotate about the axis thereof. When the driving piece 53 is started, the screw rod 51 is driven to rotate, and since the sliding block 52 is threadedly connected to the screw rod 51, the inner drawer 3 is moved along the front-rear direction.

[0056] The first magnetic pieces 6 are multiple in number and are arranged in the left-right direction in the interlayer 211 of the upper drawer. Specifically, each first magnetic piece 6 is block-shaped and tightly abuts against the rear side wall of the door body 21.

[0057] The second magnetic pieces 7 are multiple in number and are arranged in the left-right direction on the front side wall of the inner drawer 3. Specifically, each second magnetic piece 7 is block-shaped and corresponds to one of the first magnetic pieces 6, and overlaps the normal projection of the corresponding first magnetic piece 6 on the vertical plane perpendicular to the front-rear direction, so that the two can be attracted to each other when they approach each other.

[0058] The inner drawer 3 has a first position, a second position and a third position arranged in sequence from rear to front during movement;

[0059] As shown in Figure 2 , when the inner drawer 3 is in the first position, the second magnetic pieces 7 are away from the first magnetic pieces 6, as shown in Figure 4 and Figure 5 , when the inner drawer 3 is in the second position and the upper drawer is in the closed state, the second magnetic pieces 7 are attracted to the first magnetic pieces 6, so that the inner drawer 3 can drive the upper drawer to move synchronously during movement between the second position and the third position, and the upper drawer can move independently when the inner drawer 3 is in the first position.

[0060] In the embodiment, the sterilization cabinet has at least three states:

[0061] In the first state, as shown in Figure 2As shown, the upper drawer and the inner drawer 3 are in closed state, the inner drawer 3 is in the first position, and the blocking piece 31 is separated from the inlet end of the exhaust pipe 4, so that the exhaust pipe 4 is in a connected state;

[0062] In the second state, as shown in Figure 4 and Figure 5 the upper drawer and the inner drawer 3 are in closed state, the inner drawer is in the second position, and the blocking piece 31 covers the inlet end of the exhaust pipe 4, so that the exhaust pipe 4 is in a disconnected state;

[0063] In the third state, as shown in Figure 7 the upper drawer and the inner drawer 3 are in open state, and the inner drawer is in the third position.

[0064] The working principle of the embodiment is as follows: in the initial state, as shown in Figure 2 the sterilization cabinet is in the first state, the upper drawer and the inner drawer 3 are in closed state, the inner drawer 3 is in the first position, the second magnetic piece 7 is away from the first magnetic piece 6, and the blocking piece 31 is separated from the inlet end of the exhaust pipe 4, so that the exhaust pipe 4 is in a connected state;

[0065] (1) When sterilization is needed:

[0066] Start the drive piece 53 to drive the inner drawer 3 to move forward until the inner drawer 3 moves to the second position as shown in Figure 4 and Figure 5 at this time, the sterilization cabinet is in the second state, and the blocking piece 31 covers the inlet end of the exhaust pipe 4, so that the exhaust pipe 4 is in a disconnected state, and then start the sterilization device in the sterilization cavity 11, which can avoid the sterilization factor escaping to the outside atmosphere through the exhaust passage 212;

[0067] After sterilization, the inner drawer 3 is driven to reset to the initial position by the drive piece 53;

[0068] (2) When the exhaust is needed;

[0069] In the initial state, the exhaust pipe 4 is in a connected state, and due to the upward rising action of hot gas, water vapor is discharged outward through the exhaust hole 12 via the exhaust pipe 4, without the need for additional wind action to realize external exhaust;

[0070] After the exhaust is completed, there will be some wet hot gas condensed in the exhaust pipe 4 and dripping downward, at this time, the inner drawer 3 is driven to move to the second position by the drive piece 53, and the dripping downward condensed water can be collected into the water collecting tank 311, and finally the blocking piece 31 is removed to pour out the collected condensed water;

[0071] (3) When the inner drawer 3 needs to be opened and closed:

[0072] When the inner drawer 3 needs to be opened, the driving member 53 is started to rotate forward to drive the inner drawer 3 to move forward until the inner drawer 3 moves to the second position as shown in Figure 4 and Figure 5 , the second magnetic member 7 is attracted to the first magnetic member 6, at this time, the continuously moving inner drawer 3 will drive the upper drawer to move forward synchronously until both move to the third position as shown in Figure 7 , at this time, the sterilizer is in the third state;

[0073] When the inner drawer 3 needs to be closed, the driving member 53 is started to rotate reversely to drive the inner drawer 3 to move backward, since the second magnetic member 7 is attracted to the first magnetic member 6, the backward moving inner drawer 3 will drive the upper drawer to move backward synchronously until both move to the second position as shown in Figure 4 and Figure 5 , at this time, the upper drawer is in the closed state and cannot continue to move backward, therefore, in the process of the inner drawer 3 continuing to move backward to reset to the first position as shown in Figure 2 , the second magnetic member 7 will gradually move away from the first magnetic member 6, and the two are no longer attracted to each other;

[0074] In the above process, it is not necessary to open the upper drawer first and then pull the inner drawer 3, that is, the inner drawer 3 only needs one step to be automatically opened, which is simple to operate;

[0075] (4) When the upper drawer needs to be opened and closed alone:

[0076] Since the second magnetic member 7 is away from the first magnetic member 6 in the initial state, the two cannot be attracted to each other, at this time, opening the upper drawer can avoid the inner drawer 3 to be opened synchronously, thereby facilitating the taking and placing of large tableware in the upper drawer.
