Description

Technical Field

[0001] The present invention relates to the field of indoor disinfection, and particularly to a disinfection cabinet. Background Art

[0002] The disinfection cabinet includes a cabinet body, a heater, and an ultraviolet lamp. The heater heats the air inside the cabinet body, and at the same time, in cooperation with the ultraviolet lamp, realizes the disinfection and drying of tableware inside the cabinet body. However, traditional disinfection cabinets cannot be used for indoor disinfection. The reason is that after the cabinet body is opened, the air outside the cabinet body will enter the cabinet body and contact the tableware, resulting in the tableware being contaminated. At the same time, the ultraviolet light inside the cabinet body will also directly irradiate the user. Summary of the Invention

[0025] The control assembly of the present invention further includes a disinfection lamp tube, and the disinfection lamp tube is arranged in the middle of the second sleeve.

[0026] A first fan is arranged at the second air vent of the present invention, and a second fan is arranged at the third air vent.

[0027] The disinfection cabinet of the present invention has at least a first indoor disinfection state, a first in-cabinet disinfection state, and a second in-cabinet disinfection state;

[0028] When the disinfection cabinet is in the first indoor disinfection state, the fourth partition is in the second blocking state, the deflector is in the second diversion state, the control component is in the third conduction state, the first blower is in the working state, and the heater is in the working state;

[0031] The disinfection cabinet of the present invention also has a second indoor disinfection state;

[0032] When the disinfection cabinet is in the second indoor disinfection state, the fourth partition is in the second blocking state, the deflector is in the second diversion state, the control component is in the third conduction state, the first blower is in the working state, the disinfection lamp tube and the heater are both in the working state, and the power of the heater is P 1 ;

[0033] When the disinfection cabinet is in the first indoor disinfection state, the power of the heater is P 2 ;

[0034] where P 2 > P 1 .

[0035] The beneficial effects of the present invention are as follows:

[0036] The disinfection cabinet provided by the present invention can not only disinfect tableware, but also disinfect indoor air. During the process of disinfecting indoor air, it can prevent the contact between indoor air and tableware from contaminating the tableware.

[0037] Specifically as follows:

[0038] 1. When the disinfection cabinet needs to disinfect tableware, the fourth partition is in the first blocking state. Thus, the air outside the cabinet body enters the cabinet body through the first air vent and is restricted in the air exchange chamber, preventing the tableware in the upper disinfection chamber and the lower disinfection chamber from being contaminated. At the same time, the control component controls the upper disinfection chamber, the lower disinfection chamber, and the second air duct to be disconnected from the first air duct. The air outside the cabinet body entering the first air duct is restricted within the first air duct, also preventing the tableware in the upper disinfection chamber and the lower disinfection chamber from being contaminated. At this time, at least one of the upper disinfection chamber and the lower disinfection chamber is connected to the second air duct through the control component. The heater heats the air in the second air duct, and the hot air in the second air duct flows into the upper disinfection chamber and / or the lower disinfection chamber through the control component, achieving high-temperature disinfection and drying of the tableware in the upper disinfection chamber and / or the lower disinfection chamber.

[0039] 2. When the disinfection cabinet needs to disinfect the indoor air, the fourth partition is in the second blocking state. Based on the blocking and guiding effects of the fourth partition, the air outside the cabinet body enters the air exchange chamber through the first air vent and then goes to the second air vent, rather than entering the upper disinfection chamber to contaminate the tableware. This part of the air enters the second air duct through the second air vent and the third air duct and is heated and disinfected by the heater. At this time, the control component controls the second air duct and the first air duct to be conducted, so that the heated air in the second air duct can leave the cabinet body through the first air duct, thereby completing the indoor air circulation. At the same time, the upper disinfection chamber and the lower disinfection chamber are also disconnected from the first air duct and the second air duct through the control component, preventing the air outside the cabinet body from entering the upper disinfection chamber and the lower disinfection chamber through the first air duct and the second air duct to contaminate the tableware.

[0062] Example:

[0063] See Figure 1 , this embodiment provides a disinfection cabinet, including a cabinet body 1, a first partition 2, a second partition 3, a third partition 4, a fourth partition 5 and a control component 6.

[0064] The first partition 2, the second partition 3 and the third partition 4 are horizontally fixed in the cabinet body 1. Among them, the first partition 2 and the second partition 3 are arranged side by side, so the first partition 2 and the second partition 3 are generally in the same horizontal plane. In addition, the first partition 2 and the second partition 3 are also spaced apart, and the control component 6 is installed between the first partition 2 and the second partition 3. The third partition 4 is located above the first partition 2 and the second partition 3. Thus, the first partition 2, the second partition 3 and the third partition 4 divide the ventilation chamber 11, the upper disinfection chamber 12 and the lower disinfection chamber 13 in the cabinet body 1. Among them, the ventilation chamber 11 is located above the third partition 4, the upper disinfection chamber 12 is located between the first partition 2 and the third partition 4, and the lower disinfection chamber 13 is located below the first partition 2 and the second partition 3.

[0065] A first air duct 21 is provided in the first partition 2, and the first air duct 21 extends in the horizontal direction. In this embodiment, the first partition 2 is located on the left side of the control component 6, the left end of the first air duct 21 communicates with the outside of the cabinet body 1, and the right end of the first air duct 21 is located at the control component 6.

[0066] A second air duct 31 is provided in the second partition 3, and the second air duct 31 also extends in the horizontal direction. The second partition 3 is located on the right side of the control component 6, the left end of the second air duct 31 is located at the control component 6, and a heater 311 is provided in the second air duct 31.

[0067] Among them, the control component 6 can be used to control the communication states between the second air duct 31, the first air duct 21, the upper disinfection chamber 12 and the lower disinfection chamber 13. Specifically, at most one of the first air duct 21, the upper disinfection chamber 12 and the lower disinfection chamber 13 is connected to the second air duct 31 through the control component 6, and the upper disinfection chamber 12 and the lower disinfection chamber 13 are disconnected from the first air duct 21 through the control component 6.

[0068] A first ventilation opening 14 is provided on the side wall of the cabinet body 1, and the first ventilation opening 14 penetrates through the inner wall and the outer wall of the cabinet body 1 at the same time. The first ventilation opening 14 is located at the ventilation chamber 11. Therefore, the ventilation chamber 11 can be connected to the outside of the cabinet body 1 through the first ventilation opening 14, and the air outside the cabinet body 1 can enter the ventilation chamber 11 through the first ventilation opening 14.

[0069] A second ventilation opening 15 is provided on the inner wall of the cabinet body 1. The second ventilation opening 15 is located between the ventilation chamber 11 and the upper disinfection chamber 12. At the same time, the third partition 4 and the second ventilation opening 15 are arranged at intervals. The fourth partition 5 is an arc-shaped plate, and the fourth partition 5 is rotatably arranged at the second ventilation opening 15. Thus, the fourth partition 5 has a first shielding state and a second shielding state.

[0070] See Figure 2 , when the fourth partition 5 is in the first shielding state, the fourth partition 5 rotates to be at least partially located in the ventilation chamber 11. At this time, the fourth partition 5 abuts against the side wall of the ventilation chamber 11 and the edge of the third partition 4 at the same time, and the fourth partition 5 shields between the first ventilation opening 14 and the second ventilation opening 15. Thus, the first ventilation opening 14 and the second ventilation opening 15 are disconnected. At the same time, due to the avoidance effect of the fourth partition 5, the upper disinfection chamber 12 and the second ventilation opening 15 can be connected.

[0071] See Figure 3 , when the fourth partition 5 is in the second shielding state, the fourth partition 5 rotates to be at least partially located in the upper disinfection chamber 12. At this time, the fourth partition 5 abuts against the side wall of the upper disinfection chamber 12 and the edge of the third partition 4 at the same time, so that the upper disinfection chamber 12 and the second ventilation opening 15 are disconnected. At the same time, due to the avoidance effect of the fourth partition 5, the first ventilation opening 14 and the second ventilation opening 15 can be connected.

[0072] See again Figure 1 , a third air duct 16 and a fourth air duct 17 are provided in the side wall of the cabinet body 1. The third air duct 16 and the fourth air duct 17 both extend in the vertical direction. The third air duct 16 is located above the second partition 3, and the fourth air duct 17 is located below the second partition 3. The upper end of the third air duct 16 is connected to the second ventilation opening 15, and a first fan 151 is provided at the second ventilation opening 15. A third ventilation opening 18 is further provided on the inner wall of the cabinet body 1. The third ventilation opening 18 is located at the lower disinfection chamber 13, and the lower end of the fourth air duct 17 is connected to the third ventilation opening 18. The lower end of the third air duct 16 and the upper end of the fourth air duct 17 are both located at the right end of the second air duct 31.

[0073] In this embodiment, the disinfection cabinet can be used for at least tableware disinfection and indoor air disinfection.

[0074] When the disinfection cabinet needs to disinfect tableware, the fourth partition 5 is in the first blocking state to prevent the first air vent 14 from sending the outside air of the cabinet body 1 to the upper disinfection chamber 12 and the second air vent 15. After the outside air of the cabinet body 1 enters the cabinet body 1 through the first air vent 14, it is restricted in the air exchange chamber 11, avoiding the tableware in the upper disinfection chamber 12 and the lower disinfection chamber 13 from being contaminated. At the same time, the control component 6 controls the second air duct 31 and the first air duct 21 to be disconnected. At the same time, the upper disinfection chamber 12 and the lower disinfection chamber 13 are also disconnected from the first air duct 21 through the control component 6. Thus, the outside air of the cabinet body 1 enters the first air duct 21 from the left end of the first air duct 21 and is restricted in the first air duct 21, also avoiding the tableware in the upper disinfection chamber 12 and the lower disinfection chamber 13 from being contaminated. At this time, at least one of the upper disinfection chamber 12 and the lower disinfection chamber 13 is communicated with the left end of the second air duct 31 through the control component 6, and the heater 311 heats the air in the second air duct 31. The hot air in the second air duct 31 flows into the upper disinfection chamber 12 and / or the lower disinfection chamber 13 through the control component 6, realizing the high-temperature disinfection and drying of the tableware in the upper disinfection chamber 12 and / or the lower disinfection chamber 13.

[0075] When the disinfection cabinet needs to disinfect the indoor air, the fourth partition 5 is in the second blocking state, and at the same time the first fan 151 starts to draw air. Based on the blocking and guiding effects of the fourth partition 5, the outside air of the cabinet body 1 enters the air exchange chamber 11 through the first air vent 14 and then goes to the second air vent 15, rather than entering the upper disinfection chamber 12 to contaminate the tableware. This part of the air enters the second air duct 31 through the second air vent 15 and the third air duct 16 and is heated and disinfected by the heater 311. At this time, the control component 6 controls the second air duct 31 and the first air duct 21 to be conducted, so that the heated air in the second air duct 31 can leave the cabinet body 1 through the first air duct 21, forming a flow cycle of the indoor air. At the same time, the upper disinfection chamber 12 and the lower disinfection chamber 13 are also disconnected from the first air duct 21 and the second air duct 31 through the control component 6, avoiding the outside air of the cabinet body 1 from entering the upper disinfection chamber 12 and the lower disinfection chamber 13 through the first air duct 21 and the second air duct 31 to contaminate the tableware.

[0076] In this embodiment, a second fan 181 is provided at the third air vent 18, and a flap 312 is rotatably provided at the right end of the second air duct 31 to allow the tableware in the upper disinfection chamber 12 to be disinfected at high temperature alone, and also allow the tableware in the lower disinfection chamber 13 to be disinfected at high temperature alone. Among them, regardless of whether it is the case of the upper disinfection chamber 12 being disinfected at high temperature alone or the lower disinfection chamber 13 being disinfected at high temperature alone, the upper disinfection chamber 12, the lower disinfection chamber 13 and the second air duct 31 need to be disconnected from the first air duct 21 through the control component 6, and at the same time the fourth partition 5 needs to be in the first blocking state.

[0077] Among them, the flap 312 has a first guiding state and a second guiding state, and the flap 312 switches between the first guiding state and the second guiding state by rotating.

[0078] See also Figure 11 When the paddle 312 is in the first diverting state, the edge of the paddle 312 abuts against the top side wall of the second air duct 31, so that the paddle 312 blocks the space between the lower end of the third air duct 16 and the right end of the second air duct 31. At this time, the third air duct 16 and the second air duct 31 are disconnected, and at the same time, the paddle 312 also avoids the upper end of the fourth air duct 17, so that the upper end of the fourth air duct 17 and the right end of the second air duct 31 are connected.

[0079] See also Figure 9 and Figure 13 When the paddle 312 is in the second air guiding state, the edge of the paddle 312 abuts against the bottom side wall of the second air duct 31, so that the paddle 312 blocks the space between the upper end of the fourth air duct 17 and the right end of the second air duct 31. At this time, the fourth air duct 17 and the second air duct 31 are disconnected, and at the same time, the paddle 312 also avoids the lower end of the third air duct 16, so that the lower end of the third air duct 16 and the right end of the second air duct 31 are connected.

[0080] See also Figures 4 - 8 This embodiment provides one specific structure of the control component 6. Specifically, the control component 6 includes a first sleeve 61, a second sleeve 62 and a disinfection lamp tube 63.

[0081] See also Figure 4 and Figure 5 , the first sleeve 61 is provided with a first avoidance notch 611, a first through hole 612, a second through hole 613 and a third through hole 614 in sequence along its own circumference. Among them, the first avoidance notch 611 extends along the axial direction of the first sleeve 61 and penetrates to both ends of the first sleeve 61. The number of the first through holes 612, the number of the second through holes 613 and the number of the third through holes 614 are equal and multiple, so that the first through holes 612, the second through holes 613 and the third through holes 614 form a one-to-one correspondence. For the first through holes 612, the second through holes 613 and the third through holes 614 corresponding to each other, the positions of the three in the axial direction of the first sleeve 61 are consistent. The first through holes 612 are arranged in sequence at equal intervals in the axial direction of the first sleeve 61, with an interval of d. Correspondingly, the second through holes 613 are also arranged in sequence at equal intervals in the axial direction of the first sleeve 61, with an interval of d, and the third through holes 614 are also arranged in sequence at equal intervals in the axial direction of the first sleeve 61, with an interval of d.

[0082] See also Figure 10 , Figure 12 and Figure 14, the first sleeve 61 is horizontally fixed on the first partition 2 and the second partition 3. Among them, the first avoidance notch 611 is located at the left end of the second air duct 31 so that the first avoidance notch 611 communicates with the second air duct 31. The first through hole 612 is located in the upper disinfection chamber 12 so that the first through hole 612 communicates with the upper disinfection chamber 12. The second through hole 613 is located at the left end of the first air duct 21 so that the second through hole 613 communicates with the first air duct 21. The third through hole 614 is located in the lower disinfection chamber 13 so that the third through hole 614 communicates with the lower disinfection chamber 13.

[0083] See Figure 6 and Figure 7 , the disinfection lamp tube 63 is arranged through the middle of the second sleeve 62 and is spaced from the inner wall of the second sleeve 62. In addition, the ends of the second sleeve 62 are sealed. The second sleeve 62 is sequentially provided with a fourth through hole 621, a fifth through hole 622, a sixth through hole 623, and a seventh through hole 624 along its circumferential direction. The number of the fourth through holes 621, the number of the fifth through holes 622, the number of the sixth through holes 623, and the number of the seventh through holes 624 are equal and there are multiple, so that the fourth through hole 621, the fifth through hole 622, the sixth through hole 623, and the seventh through hole 624 are in a one-to-one correspondence with each other. For the correspondingly arranged fourth through hole 621, fifth through hole 622, sixth through hole 623, and seventh through hole 624, in the axial direction of the second sleeve 62, the positions of the fifth through hole 622, the sixth through hole 623, and the seventh through hole 624 are kept consistent and flush, while the fourth through hole 621 is staggered, and the staggering distance is d. Adapted to the structure of the first sleeve 61, the fourth through holes 621 are sequentially equidistantly arranged in the axial direction of the second sleeve 62 at an interval of d, the fifth through holes 622 are sequentially equidistantly arranged in the axial direction of the second sleeve 62 at an interval of d, the sixth through holes 623 are sequentially equidistantly arranged in the axial direction of the second sleeve 62 at an interval of d, and the seventh through holes 624 are sequentially equidistantly arranged in the axial direction of the second sleeve 62 at an interval of d.

[0084] See Figure 8 , the second sleeve 62 is rotatably arranged in the middle of the first sleeve 61, and the inner wall of the first sleeve 61 is in contact with the second sleeve 62. Among them, the fourth through hole 621, the first through hole 612, the second through hole 613, and the third through hole 614 are flush in the axial direction of the first sleeve 61. Correspondingly, the fifth through hole 622, the sixth through hole 623, and the seventh through hole 624 will be staggered from the first through hole 612, the second through hole 613, and the third through hole 614 in the axial direction of the second sleeve 62.

[0085] Correspondingly, the control component 6 has at least a first conduction state, a second conduction state, and a third conduction state. Through the rotation of the second sleeve 62, the control component 6 can be switched between the first conduction state, the second conduction state, and the third conduction state.

[0086] See Figure 10 When the control component 6 is in the first conduction state, the fourth through hole 621 is located at the first through hole 612 and communicates with the first through hole 612. Thus, the fourth through hole 621 can communicate with the upper disinfection chamber 12. The seventh through hole 624 is located at the first avoidance notch 611, and the seventh through hole 624 communicates with the left end of the second air duct 31 through the first avoidance notch 611. Therefore, the left end of the second air duct 31 can communicate with the upper disinfection chamber 12 through the control component 6. At the same time, the fifth through hole 622 is located at the right end of the first air duct 21, and the sixth through hole 623 is located at the lower disinfection chamber 13. However, the inner wall of the first sleeve 61 blocks both at the fifth through hole 622 and the sixth through hole 623, so that both the right end of the first air duct 21 and the lower disinfection chamber 13 are kept disconnected from the inside of the second sleeve 62. Correspondingly, both the right end of the first air duct 21 and the lower disinfection chamber 13 are disconnected from the upper disinfection chamber 12 and the left end of the second air duct 31 through the control component 6.

[0087] See Figure 12 When the control component 6 is in the second conduction state, the fourth through hole 621 is located at the third through hole 614 and communicates with the third through hole 614. Thus, the fourth through hole 621 can communicate with the lower disinfection chamber 13. The fifth through hole 622 is located at the first avoidance notch 611, and the fifth through hole 622 communicates with the left end of the second air duct 31 through the first avoidance notch 611. Therefore, the left end of the second air duct 31 can communicate with the lower disinfection chamber 13 through the control component 6. At the same time, the sixth through hole 623 is located at the upper disinfection chamber 12, and the seventh through hole 624 is located at the right end of the first air duct 21. However, the inner wall of the first sleeve 61 blocks both at the sixth through hole 623 and the seventh through hole 624, so that both the right end of the first air duct 21 and the upper disinfection chamber 12 are kept disconnected from the inside of the second sleeve 62. Correspondingly, both the right end of the first air duct 21 and the upper disinfection chamber 12 are disconnected from the lower disinfection chamber 13 and the left end of the second air duct 31 through the control component 6.

[0088] See Figure 14 When the control component 6 is in the third conduction state, the fourth through hole 621 is located at the second through hole 613 and communicates with the second through hole 613. Thus, the fourth through hole 621 can communicate with the right end of the first air duct 21. The sixth through hole 623 is located at the first avoidance notch 611, and the sixth through hole 623 communicates with the left end of the second air duct 31 through the first avoidance notch 611. Therefore, the left end of the second air duct 31 can communicate with the right end of the first air duct 21 through the control component 6. At the same time, the fifth through hole 622 is located at the lower disinfection chamber 13, and the seventh through hole 624 is located at the upper disinfection chamber 12. However, the inner wall of the first sleeve 61 blocks both at the fifth through hole 622 and the seventh through hole 624, so that both the lower disinfection chamber 13 and the upper disinfection chamber 12 are kept disconnected from the inside of the second sleeve 62. Correspondingly, both the lower disinfection chamber 13 and the upper disinfection chamber 12 are disconnected from the left end of the second air duct 31 and the right end of the first air duct 21 through the control component 6.

[0089] Based on the above structure, the disinfection cabinet of this embodiment has at least a first indoor disinfection state, a second indoor disinfection state, a first inner cabinet disinfection state, and a second inner cabinet disinfection state.

[0090] See Figure 13 and Figure 14 , when the disinfection cabinet is in the first indoor disinfection state, the fourth partition 5 is in the second blocking state, the deflector 312 is in the second diversion state, the control component 6 is in the third conduction state, the first fan 151 is in the working state, the heater 311 is in the working state, and the disinfection lamp tube 63 can be in the working state or in the non-working state. At this time, the power of the heater 311 is P 2 , P 2 The value is relatively large, and the air outside the cabinet body 1 can be at least disinfected at high temperature after entering the second air duct 31. It is easy to understand that after the hot air returns to the outside of the cabinet body 1 through the first air duct 21, it will cause the indoor temperature to rise rapidly.

[0091] Similarly see Figure 13 and Figure 14 , when the disinfection cabinet is in the second indoor disinfection state, the fourth partition 5 is in the second blocking state, the deflector 312 is in the second diversion state, the control component 6 is in the third conduction state, and the first fan 151 is in the working state. Different from the first indoor disinfection state, at this time, both the disinfection lamp tube 63 and the heater 311 are in the working state, and the power of the heater 311 is P 1 is small, at least satisfying P 2 > P 1 . It is not difficult to understand that although the air outside the cabinet body 1 will be heated and disinfected after entering the second air duct 31, the temperature rise effect and disinfection effect are limited. After this part of the air enters the second sleeve 62, it will be further disinfected by ultraviolet rays to ensure the final disinfection effect of this part of the air. After this part of the air returns to the outside of the cabinet body 1 through the first air duct 21, it will not cause the indoor temperature to rise too fast and avoid discomfort to the user.

[0092] See Figure 9 and Figure 10, when the disinfection cabinet is in the first in-cabinet disinfection state, the fourth partition 5 is in the first blocking state, the flap 312 is in the second diversion state, the control component 6 is in the first conduction state, the first blower 151 is in the working state, the second blower 181 is in the non-working state, and the heater 311 is in the working state. Preferably, the disinfection lamp tube 63 can also be in the working state. At this time, the air in the upper disinfection chamber 12 can circulate through the second air exchange port 15, the third air duct 16, the second air duct 31 and the control component 6, so that the heater 311 heats and disinfects the air in the upper disinfection chamber 12. At the same time, the ultraviolet light of the disinfection lamp tube 63 can also be emitted into the upper disinfection chamber 12 through the first through hole 612 and the fourth through hole 621 to perform ultraviolet disinfection on the tableware in the upper disinfection chamber 12. At this time, due to the blocking effect of the flap 312 and the control component 6, the air between the upper disinfection chamber 12 and the lower disinfection chamber 13 does not flow to each other, thereby realizing the separate disinfection of the tableware in the upper disinfection chamber 12.

[0093] See Figure 11 and Figure 12 , when the disinfection cabinet is in the second in-cabinet disinfection state, the fourth partition 5 is in the first blocking state, the flap 312 is in the first diversion state, the control component 6 is in the second conduction state, the first blower 151 is in the non-working state, the second blower 181 is in the working state, and the heater 311 is in the working state. Preferably, the disinfection lamp tube 63 can also be in the working state. At this time, the air in the lower disinfection chamber 13 can circulate through the third air exchange port 18, the fourth air duct 17, the second air duct 31 and the control component 6, so that the heater 311 heats and disinfects the air in the lower disinfection chamber 13. At the same time, the ultraviolet light of the disinfection lamp tube 63 can also be emitted into the lower disinfection chamber 13 through the fourth through hole 621 and the third through hole 614 to perform ultraviolet disinfection on the tableware in the lower disinfection chamber 13. At this time, due to the blocking effect of the flap 312 and the control component 6, the air between the upper disinfection chamber 12 and the lower disinfection chamber 13 does not flow to each other, thereby realizing the separate disinfection of the tableware in the lower disinfection chamber 13.
