[0045] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] like Figures 1 to 9 As shown, this embodiment provides a ventilation structure, which is applied to tableware processing equipment (such as disinfection cabinets, dryers, etc.), which can reduce the manufacturing cost of the equipment and improve the use effect and user experience of the tableware processing equipment.

[0049] like Figure 1 and Figure 2 As shown, the dishware processing device includes a first chamber 101 and a second chamber 102, and the ventilation structure includes a fan 1 and an air duct 2. The air duct 2 has a first vent 211, a second vent 221 and a third vent 231 (as shown in FIG. Figure 7 As shown), the first ventilation port 211 is connected to the ventilation end of the fan 1, the second ventilation port 221 is selectively connected to the first chamber 101, and the third ventilation port 231 is selectively connected to the second chamber 102.

[0050] The ventilation structure provided in this embodiment, by setting a fan 1 and an air duct 2, and setting a second vent 221 and a third vent 231 on the air duct 2, allows the first chamber 101, the second chamber 102 of the tableware processing equipment to be selectively connected to the outside world, and the first chamber 101 and the second chamber 102 to be selectively connected. When a single chamber is working, the air duct 2 is only connected to the corresponding chamber, and ventilation and dehumidification are performed through the fan 1 to prevent the dual chamber environments from interfering with each other and affecting the cleanliness of the other chamber. When the dual chambers are working at the same time, the air duct 2 can connect the first chamber 101 and the second chamber 102, and ventilation and dehumidification can be performed using the same fan 1 and air duct 2. The structural design is simple, can reduce manufacturing costs, and improve the user experience of the tableware processing equipment.

[0051] Specifically, Figure 2 As shown, when the tableware processing device is not working, the second vent 221 is not connected to the first chamber 101, and the third vent 231 is not connected to the second chamber 102, which can isolate the external air circulation and ensure the clean state of the first chamber 101 and the second chamber 102. If only the first chamber 101 (second chamber 102) is working, such as entering the disinfection mode, the second vent 221 is disconnected from the first chamber 101 (the third vent 231 is disconnected from the second chamber 102), which can ensure that the first chamber 101 (the second chamber 102) is relatively closed, improve the disinfection effect, and will not cause harm to the user; if entering the drying mode, the second vent 221 is connected to the first chamber 101 (the third vent 231 is connected to the second chamber 102), and the wind generated by the fan 1 enters the first chamber 101 (the second chamber 102), which can accelerate the flow of hot air in the first chamber 101 (the second chamber 102), increase the temperature rise rate and make the temperature distribution more uniform, thereby improving the tableware drying efficiency. After the drying is completed, the fan 1 is controlled to start the suction to discharge the moisture in the first chamber 101 (the second chamber 102), ensure that the first chamber 101 (the second chamber 102) is dry and avoid the generation of odor.

[0052] like Figure 3 and Figure 5As shown, when the first chamber 101 and the second chamber 102 are working at the same time, after the drying module is started, the second vent 221 is connected to the first chamber 101, and the third vent 231 is connected to the second chamber 102. The wind energy generated by the fan 1 enters the first chamber 101 and the second chamber 102 at the same time, accelerating the flow of hot air in the first chamber 101 and the second chamber 102, increasing the temperature rise rate and temperature uniformity, and simultaneously improving the drying efficiency of the first chamber 101 and the second chamber 102; after the drying is completed, the fan 1 is controlled to start suction, which can simultaneously discharge the moisture in the first chamber 101 and the second chamber 102, ensuring the cleaning effect of the first chamber 101 and the second chamber 102. Figure 5 , which is a schematic diagram of the air flow direction when the first chamber 101 and the second chamber 102 are both connected to the air duct 2. In the figure, the directions indicated by the arrows in the first chamber 101 and the second chamber 102 are the air flow directions.

[0053] Optionally, see Figure 2 , Figure 3 and Figure 4 The second vent 221 is provided with a first sealing plate 3, which can block or open the second vent 221; the third vent 231 is provided with a second sealing plate 4, which can block or open the third vent 231. By controlling the first sealing plate 3, the second vent 221 can be selectively connected to the first chamber 101, and by controlling the second sealing plate 4, the third vent 231 can be selectively connected to the second chamber 102.

[0054] Specifically in this embodiment, Figure 2 , Figure 3 and Figure 6 As shown, a first lock hook 201 is provided on the first door body (not shown) of the first chamber 101. When the first door body is closed, the first lock hook 201 can lock the first door body and drive the first sealing plate 3 to open the second vent 221. A second lock hook 301 is provided on the second door body of the second chamber 102. When the second door body is closed, the second lock hook 301 can lock the second door body and drive the second sealing plate 4 to open the third vent 231. In this way, the first lock hook 201 and the second lock hook 301 are linked to the opening and closing states of the first sealing plate 3 and the second sealing plate 4. When the first lock hook 201 and the second lock hook 301 are locked and unlocked, the opening and closing of the second vent 221 and the third vent 231 can be controlled. No additional driving mechanism is required, which can simplify the structure of the ventilation device and further reduce the processing cost of the ventilation structure.

[0055] In this embodiment, a first electromagnetic lock 200 is disposed on the first door body, and the first lock hook 201 is the lock hook of the first electromagnetic lock 200 . A second electromagnetic lock 300 is disposed on the second door body, and the second lock hook 301 is the lock hook of the second electromagnetic lock 300 .

[0056] Optionally, the first lock hook 201 and the second lock hook 301 both have a first gear and a second gear. When the first lock hook 201 is in the first gear, it can lock the bowl rack 400 in the first chamber 101, and when the first lock hook 201 is in the second gear, it can lock the bowl rack 400 in the first chamber 101 and drive the first sealing plate 3 to open the second vent 221; when the second lock hook 301 is in the first gear, it can lock the bowl rack 400 in the second chamber 102, and when the second lock hook 301 is in the second gear, it can lock the bowl rack 400 in the second chamber 102 and drive the second sealing plate 4 to open the third vent 231. Such a configuration can ensure that the first door body and the second door body are closed securely, and can also achieve the selective opening of the first sealing plate 3 and the second sealing plate 4.

[0057] In this embodiment, refer to Figure 2 and Figure 3 In the orientation, when the first door body is closed and the first electromagnetic lock 200 is locked to the first gear, the first lock hook 201 moves upward to hook the tail end beam of the bowl rack 400 to ensure that the first door body is securely closed. When the first electromagnetic lock 200 is locked to the second gear, the first lock hook 201 moves upward to hook the tail end beam of the bowl rack 400, and at the same time pushes the first sealing plate 3 to open the second vent 221, so that the first chamber 101 is connected with the air duct 2. After the fan 1 is started, the external air can be introduced into the first chamber 101, so that the air in the first chamber 101 circulates faster and increases the heating rate; or the fan 1 draws the air in the first chamber 101 through the air duct 2, discharges the moisture in the first chamber 101, and ensures that the first chamber 101 is dry. The working principle of the second electromagnetic lock 300 is the same as that of the first electromagnetic lock 200, which will not be repeated here.

[0058] Optionally, the area of ​​the second vent 221 blocked by the first sealing plate 3 is adjustable; the area of ​​the third vent 231 blocked by the second sealing plate 4 is adjustable. By adjusting the area of ​​the second vent 221 blocked by the first sealing plate 3, the circulation speed of the air in the first chamber 101 can be adjusted, thereby adjusting the temperature rise speed in the first chamber 101 to meet the processing requirements of different tableware. By adjusting the area of ​​the third vent 231 blocked by the second sealing plate 4, the circulation speed of the air in the second chamber 102 can be adjusted, thereby adjusting the temperature rise speed in the second chamber 102 to meet the processing requirements of different tableware.

[0059] In this embodiment, refer to Fig. 9The first sealing plate 3 is rotatably connected to the second vent 221 of the air duct 2 through the first rotating shaft 31, and the rotation angle of the first sealing plate 3 is adjustable; the second sealing plate 4 is rotatably connected to the third vent 231 of the air duct 2 through the second rotating shaft, and the rotation angle of the second sealing plate 4 is adjustable. Specifically, a first rotating hole can be provided at the second vent 221 of the air duct 2, and the first rotating shaft 31 penetrates into the first rotating hole and rotatably cooperates with the first rotating hole to realize the rotational connection between the first sealing plate 3 and the air duct 2. A second rotating hole is provided at the third vent 231 of the air duct 2, and the second rotating shaft penetrates into the second rotating hole and rotatably cooperates with the second rotating hole to realize the rotational connection between the second sealing plate 4 and the air duct 2. When the first electromagnetic lock 200 is unlocked, the first lock hook 201 descends to disengage from the bowl rack 400, and the first sealing plate 3 rotates under its own gravity to block the second vent 221; when the second electromagnetic lock 300 is unlocked, the second lock hook 301 descends to disengage from the bowl rack 400, and the second sealing plate 4 rotates under its own gravity to block the third vent 231.

[0060] By controlling the upward movement distance of the first locking hook 201 and the second locking hook 301, the rotation angle of the first sealing plate 3 and the second sealing plate 4 can be adjusted accordingly, thereby changing the area of ​​the second vent 221 blocked by the first sealing plate 3 and changing the area of ​​the third vent 231 folded by the second sealing plate 4, thereby adjusting the ventilation volume of the second vent 221 and the third vent 231 and changing the air circulation speed of the first chamber 101 and the second chamber 102.

[0061] In other embodiments, the first sealing plate 3 and the second sealing plate 4 may also be slidably disposed at the first ventilation opening 211 and the second ventilation opening 221 respectively, and the opening and closing of the first sealing plate 3 and the second sealing plate 4 may be controlled by sliding.

[0062] Optionally, see Fig. 9 The first sealing plate 3 is provided with a first sealing member 32, and the first sealing plate 3 is in sealing contact with the inner wall of the air duct 2 through the first sealing member 32; the second sealing member is provided with a second sealing member, and the second sealing plate 4 is in sealing contact with the inner wall of the air duct 2 through the second sealing member. The design of the first sealing member 32 and the second sealing member can, on the one hand, create friction between the first sealing member 3 and the second sealing member 4 and the inner wall of the air duct 2, thereby preventing the first sealing member 3 and the second sealing member 4 from rotating downward and opening in a natural state (refer to Figure 2 and Figure 3 on the other hand, the first sealing member 32 enables the first sealing plate 3 to seal and block the second ventilation opening 221, and the second sealing member enables the second sealing plate 4 to seal and block the third ventilation opening 231, thereby ensuring the airtightness of the first chamber 101 and the second chamber 102.

[0063] Exemplarily, the first sealing member 32 is a sealing ring arranged around the first sealing plate 3 to ensure that the first sealing plate 3 is in sealing contact with the inner wall of the air duct 2 along the entire circumference; the second sealing member is a sealing ring arranged around the second sealing plate 4 to ensure that the second sealing plate 4 is in sealing contact with the inner wall of the air duct 2 along the entire circumference.

[0064] Optionally, see Figure 1 and Figure 7 The air duct 2 includes a main channel 21 and a first branch channel 22 and a second branch channel 23 arranged at intervals in the main channel 21. The end of the first branch channel 22 away from the main channel 21 is connected to the first chamber 101, and the end of the second branch channel 23 away from the main channel 21 is connected to the second chamber 102. The second vent 221 is the opening of the end of the first branch channel 22 away from the main channel 21, and the third vent 231 is the opening of the end of the second branch channel 23 away from the main channel 21. With such an arrangement, one fan 1 and one air duct 2 can realize the selective connection between the first chamber 101 and the second chamber 102. Whether the first chamber 101 and the second chamber 102 work simultaneously or separately, they can effectively increase the temperature rise rate in the chamber, and ventilate and dehumidify after the drying is completed.

[0065] Optionally, see Figure 7 The first branch channel 22 is provided with a first extension part 223 at one end away from the main channel 21, and the first extension part 223 extends along the height direction of the inner pot 100 of the tableware processing device, so that the second vent 221 is directly opposite to the first lock hook 201. The second branch channel 23 is provided with a second extension part 232 at one end away from the main channel 21, and the second extension part 232 extends along the height direction of the inner pot 100, so that the third vent 231 is directly opposite to the second lock hook 301. The first extension part 223 and the second extension part 232 are provided so that the second vent 221 is directly opposite to the first lock hook 201, and the third vent 231 is directly opposite to the second lock hook 301. When the first lock hook 201 and the second lock hook 301 move upward, they can respectively push the first sealing plate 3 and the second sealing plate 4 to rotate and open, so as to realize the conduction of the second vent 221 and the third vent 231.

[0066] Optionally, see Figure 7 and Fig. 9 The first branch channel 22 and the second branch channel 23 are both provided with a clamping structure 222, which is configured to clamp with the inner container 100 of the tableware processing device. A clamping opening is reserved at a corresponding position of the inner container 100, and after the second vent 221 and the third vent 231 pass through the corresponding clamping opening, the clamping structure 222 can be hooked on the edge of the clamping opening, so that the air duct 2 is firmly installed on the inner container 100.

[0067] Exemplarily, the clamping structure 222 is an L-shaped clamping hook disposed on the side wall of the first branch channel 22 (the second branch channel 23 ), and two clamping structures 222 are symmetrically arranged to ensure a secure clamping connection.

[0068] Optionally, a first plug-in structure is provided at the first vent 211 of the air duct 2, and a second plug-in structure is provided at the ventilation end of the fan 1, and the first plug-in structure is plugged with the second plug-in structure. The first plug-in structure and the second plug-in structure are plugged together to realize the rapid disassembly and assembly of the fan 1 and the air duct 2.

[0069] Furthermore, a disinfection module and a drying module are provided in the first chamber 101 and the second chamber 102. The disinfection module is used to disinfect the tableware in the first chamber 101 and the second chamber 102, and the drying module is used to dry the tableware. Figure 6 As shown, optionally, the disinfection module includes a disinfection lamp 500, which can disinfect the tableware in the first chamber 101 (the second chamber 102) after being lit.

The cylindrical protrusion 212 can be inserted into the plug hole 11 to achieve the limit of the air duct 2 and the fan 1. Exemplarily, the two opposite outer walls of the air duct 2 are both provided with cylindrical protrusions 212, and correspondingly, the ventilation end of the fan 1 is provided with two plug holes 11, and the two cylindrical protrusions 212 are plugged into the two plug holes 11 in a one-to-one correspondence, further improving the connection stability between the air duct 2 and the fan 1.

[0071] In other embodiments, the first plug-in structure may also be a slot arranged on the inner wall of the air duct 2, and the second plug-in structure includes a hook arranged on the ventilation end of the fan 1. The air duct 2 can be sleeved on the ventilation end of the fan 1, and the hook is elastically connected to the slot to achieve the plug-in of the air duct 2 and the ventilation end of the fan 1.

[0072] This embodiment also provides a tableware processing device, including a box body, an inner tank 100 and the ventilation structure as described above, wherein the inner tank 100 is arranged in the box body, the inner tank 100 is divided into a first chamber 101 and a second chamber 102, and the ventilation structure is arranged outside the inner tank 100.
