Description

Technical Field

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

[0002] The disinfection cabinet includes a cabinet body, a plurality of grilles and ultraviolet lamps. The grilles and ultraviolet lamps are both arranged in the cabinet body. The grilles divide the cabinet body into at least two disinfection chambers. After the ultraviolet lamps are turned on, all the disinfection chambers are irradiated through the gaps on the grilles. However, when the number of tableware in the cabinet body is small, only the disinfection chamber with tableware needs to be irradiated by ultraviolet light. At this time, the ultraviolet light in the disinfection chamber without tableware is significantly wasted, and the energy consumption of the disinfection cabinet is wasted. Summary of the Invention

[0003] Based on this, it is necessary to provide a disinfection cabinet aiming at the problem of energy consumption waste of the disinfection cabinet.

[0004] A disinfection cabinet, comprising:

[0005] A cabinet body;

[0006] A first partition board, which is arranged in the cabinet body to divide the interior of the cabinet body into a first disinfection chamber and a second disinfection chamber. A first air outlet is arranged on the first partition board, and the first air outlet is located between the first disinfection chamber and the second disinfection chamber;

[0007] An ultraviolet lamp tube, which is rotatably arranged between the first disinfection chamber and the second disinfection chamber. The ultraviolet lamp tube is located at the first air outlet and is spaced from the first air outlet; and

[0008] A diversion block, which is installed on the ultraviolet lamp tube and is used to block the first air outlet or change the air flow direction at the first air outlet;

[0009] The ultraviolet lamp tube has a first angular state, a second angular state and a third angular state. When the ultraviolet lamp tube is in the first angular state, the first air outlet is only communicated with the first disinfection chamber. When the ultraviolet lamp tube is in the second angular state, the first air outlet is only communicated with the second disinfection chamber. When the ultraviolet lamp tube is in the third angular state, the first air outlet is simultaneously communicated with the first disinfection chamber and the second disinfection chamber.

[0010] The disinfection cabinet of the present invention further includes a second partition board, which is located between the first disinfection chamber and the second disinfection chamber. The ultraviolet lamp tube is located between the first partition board and the second partition board, and the second partition board and the ultraviolet lamp tube are spaced apart.

[0011] The edge of the second partition board of the present invention is provided with a reflective surface, and the reflective surface is arranged opposite to the ultraviolet lamp tube.

[0012] The flow guiding block, the first air outlet, and the reflecting surface of the present invention all extend along the axial direction of the ultraviolet lamp tube. The cross-section of the flow guiding block is fan-shaped, and the reflecting surface is a cylindrical surface. When the ultraviolet lamp tube is in the third angle state, the flow guiding block fits against the reflecting surface, and the ultraviolet lamp tube is in the on state.

[0013] The ultraviolet lamp tube of the present invention further has a fourth angle state. When the ultraviolet lamp tube is in the fourth angle state, the flow guiding block blocks the first air outlet, and the ultraviolet lamp tube is in the off state.

[0014] The gap between the upper surface of the first partition plate and the upper surface of the second partition plate of the present invention is the second air outlet. When the ultraviolet lamp tube is in the second angle state, the flow guiding block blocks the second air outlet.

[0015] The gap between the lower surface of the first partition plate and the lower surface of the second partition plate of the present invention is the third air outlet. When the ultraviolet lamp tube is in the first angle state, the flow guiding block blocks the third air outlet.

[0016] A first air duct is provided inside the first partition plate of the present invention. A circulation air outlet is provided on the side wall of the first disinfection chamber or the second disinfection chamber. Both the first air outlet and the circulation air outlet communicate with the first air duct.

[0017] The disinfection cabinet of the present invention further includes a flow guiding plate. The flow guiding plate is installed on the first partition plate and is located outside the first disinfection chamber and the second disinfection chamber. A second air duct is provided inside the flow guiding plate. The circulation air outlet and the first air duct communicate with the two ends of the second air duct respectively. An air discharge port communicating with the second air duct is further provided on the flow guiding plate. A cover plate is provided at the air discharge port. An elastic member is provided between the cover plate and the inner wall of the second air duct.

[0018] A heater is provided inside the first air duct of the present invention.

[0019] The beneficial effects of the present invention are as follows:

[0020] When the ultraviolet lamp tube is in the first angle state, the first air outlet only communicates with the first disinfection chamber. Therefore, the hot air blown out at the first air outlet can only enter the first disinfection chamber. Due to the blocking of the flow guiding block, the ultraviolet light emitted by the ultraviolet lamp tube irradiates the first disinfection chamber and will not irradiate the second disinfection chamber. The ozone generated by the excitation of ultraviolet light will also only enter the first disinfection chamber. The ultraviolet light, hot air, and ozone are all fully used for the disinfection of tableware in the first disinfection chamber and will not be wasted in the second disinfection chamber.

[0021] Similarly, when the ultraviolet lamp tube is in the second angle state, ultraviolet light, hot air, and ozone are all fully utilized for disinfecting tableware in the second disinfection chamber and will not be wasted in the first disinfection chamber.

[0022] When the ultraviolet lamp tube is in the third angle state, the first disinfection chamber and the second disinfection chamber can be connected, and ultraviolet light, hot air, and ozone can be simultaneously used for the disinfection operations of the first disinfection chamber and the second disinfection chamber.

[0023] The disinfection cabinet of the present invention can disinfect only the first disinfection chamber, only the second disinfection chamber, or both the first disinfection chamber and the second disinfection chamber according to needs, thereby reducing energy consumption and waste of disinfection substances.

[0043] Embodiment:

[0044] See Figures 1-4 , this embodiment provides a disinfection cabinet, which includes a cabinet body 1, a first partition 2, an ultraviolet lamp tube 3, a diversion block 4 and a second partition 5.

[0045] The first partition 2 and the second partition 5 are both horizontally disposed in the cabinet body 1. The first partition 2 and the second partition 5 are generally in the same plane, thereby dividing the internal space of the cabinet body 1 into a first disinfection chamber 11 and a second disinfection chamber 12. Correspondingly, the first partition 2 and the second partition 5 are both located between the first disinfection chamber 11 and the second disinfection chamber 12. The first partition 2 and the second partition 5 can both be used for placing tableware, and the second partition 5 is located on the left side of the first partition 2. Since the first partition 2 and the second partition 5 are not grilles, the first disinfection chamber 11 and the second disinfection chamber 12 cannot be communicated through the first partition 2 and the second partition 5.

[0046] A first air outlet 21 is provided at the left edge of the first partition plate 2. The first air outlet 21 is located between the upper surface and the lower surface of the first partition plate 2. Correspondingly, the first air outlet 21 is also located between the first disinfection chamber 11 and the second disinfection chamber 12. The first partition plate 2 and the second partition plate 5 are arranged at intervals to prevent the right edge of the second partition plate 5 from blocking the first air outlet 21. A first air duct is provided inside the first partition plate 2, and the first air outlet 21 communicates with the first air duct. A heater is provided inside the first air duct to allow hot air to be blown out at the first air outlet 21.

[0047] The ultraviolet lamp tube 3 is installed on the cabinet body 1 and is rotatably arranged. The ultraviolet lamp tube 3 is located between the first partition plate 2 and the second partition plate 5, so the ultraviolet lamp tube 3 is also located between the first disinfection chamber 11 and the second disinfection chamber 12.

[0048] The flow guide block 4 is installed on the outer wall of the ultraviolet lamp tube 3 so that the flow guide block 4 rotates synchronously with the ultraviolet lamp tube 3. The right edge of the second partition plate 5 and the first air outlet 21 are both arranged at intervals with the ultraviolet lamp tube 3 to leave a space for the flow guide block 4 to rotate.

[0049] In this embodiment, the flow guide block 4 is columnar, the cross section of the flow guide block 4 is fan-shaped, and the axis of the flow guide block 4 is parallel to the axis of the ultraviolet lamp tube 3. A reflecting surface 51 is provided at the right edge of the second partition plate 5, and the reflecting surface 51 is coated with a material capable of reflecting ultraviolet light. The reflecting surface 51, the ultraviolet lamp tube 3 and the first air outlet 21 are arranged in sequence in the radial direction of the ultraviolet lamp tube 3. The reflecting surface 51 and the first air outlet 21 both extend along the axial direction of the ultraviolet lamp tube 3. The reflecting surface 51 and the first air outlet 21 are both arc surfaces, and the diameters of the reflecting surface 51 and the first air outlet 21 both match the outer diameter of the flow guide block 4. Among them, the gap between the upper surface of the first partition plate 2 and the upper surface of the second partition plate 5 is the second air outlet 22, and the gap between the lower surface of the first partition plate 2 and the lower surface of the second partition plate 5 is the third air outlet 23.

[0050] According to the rotation angle of the ultraviolet lamp tube 3, the ultraviolet lamp tube 3 has a first angular state, a second angular state, a third angular state and a fourth angular state.

[0051] See Figure 3 and Figure 4, when the ultraviolet lamp tube 3 is in the first angular state, the flow guide block 4 avoids the second air outlet 22 and the first air outlet 21 to ensure the communication between the first air outlet 21 and the second air outlet 22. At this time, the first air outlet 21 can be connected to the first disinfection chamber 11 located above the first partition 2. Therefore, the hot air blown out from the first air outlet 21 can enter the first disinfection chamber 11, and the tableware in the first disinfection chamber 11 can obtain the disinfection and drying of the hot air. At the same time, the flow guide block 4 blocks the third air outlet 23 to block the air flow between the first air outlet 21 and the second disinfection chamber 12 located below the first partition 2. Thus, the hot air blown out from the first air outlet 21 can only be used for drying and disinfecting in the first disinfection chamber 11, avoiding the waste of hot air. In addition, since the second air outlet 22 is not blocked by the flow guide block 4, the ultraviolet lamp tube 3 can also directly irradiate the first disinfection chamber 11 through the second air outlet 22 to allow the ultraviolet disinfection of the tableware in the first disinfection chamber 11. The outer wall surface of the flow guide block 4 (including the connection between the ultraviolet lamp tube 3 and the flow guide block 4) is also coated with a material capable of reflecting ultraviolet light. The ultraviolet light emitted by the ultraviolet lamp tube 3 that fails to directly irradiate the first disinfection chamber 11 can enter the first disinfection chamber 11 through the reflection of the reflecting surface 51 and the outer wall surface of the flow guide block 4. Thus, almost all the ultraviolet light emitted by the ultraviolet lamp tube 3 is used for disinfecting the tableware in the first disinfection chamber 11 and will not enter the second disinfection chamber 12, thereby reducing the waste of ultraviolet light. The oxygen at the location of the first disinfection chamber 11 and the ultraviolet lamp tube 3 will be directly converted into ozone after being catalyzed by ultraviolet light irradiation. Moreover, the ozone at the location of the ultraviolet lamp tube 3 can enter the first disinfection chamber 11 along with the hot air flow at the first air outlet 21 to allow all the generated ozone to be used for disinfecting the tableware in the first disinfection chamber 11. Thus, it can be seen that when the ultraviolet lamp tube 3 is in the first angular state, the ultraviolet light, hot air, and ozone are all fully used for disinfecting the tableware in the first disinfection chamber 11, with almost no waste.

[0052] See Figure 5 and Figure 6, when the ultraviolet lamp tube 3 is in the second angular state, the flow guide block 4 blocks the second air outlet 22 and avoids the first air outlet 21, thereby blocking the hot air flow between the first air outlet 21 and the first disinfection chamber 11. The hot air blown out at the first air outlet 21 will not enter the first disinfection chamber 11, and the ozone at the ultraviolet lamp tube 3 will not flow into the first disinfection chamber 11 either. At the same time, the flow guide block 4 also avoids the third air outlet 23. The first air outlet 21 can communicate with the second disinfection chamber 12 located below the first partition 2 through the third air outlet 23, so as to allow all the hot air blown out at the first air outlet 21 to be used for drying and disinfecting tableware in the second disinfection chamber 12. The ozone generated at the ultraviolet lamp tube 3 can also enter the second disinfection chamber 12 along with the hot air flow. At the same time, through the avoidance of the third air outlet 23, part of the ultraviolet light emitted by the ultraviolet lamp tube 3 can directly irradiate the second disinfection chamber 12 for ultraviolet disinfection, and convert the oxygen in the second disinfection chamber 12 into ozone. The ultraviolet light emitted by the ultraviolet lamp tube 3 that fails to directly irradiate the second disinfection chamber 12 can also enter the second disinfection chamber 12 through the reflection of the reflecting surface 51 and the outer wall surface of the flow guide block 4. Thus, when the ultraviolet lamp tube 3 is in the second angular state, the ultraviolet light, hot air and ozone are all fully used for disinfecting tableware in the second disinfection chamber 12, with little waste.

[0053] See Figure 7 and Figure 8 , when the ultraviolet lamp tube 3 is in the third angular state, the flow guide block 4 and the reflecting surface 51 are attached to avoid the first air outlet 21, the second air outlet 22 and the third air outlet 23 at the same time. The first air outlet 21 communicates with the second air outlet 22 and the third air outlet 23 at the same time, and the ultraviolet lamp tube 3 is still in the on state. The hot air blown out at the first air outlet 21 can be split into the second air outlet 22 and the third air outlet 23, and then enter the first disinfection chamber 11 and the second disinfection chamber 12 respectively for hot air disinfection. The ozone generated at the ultraviolet lamp tube 3 can also enter the first disinfection chamber 11 and the second disinfection chamber 12 along with the hot air flow. In addition, the ultraviolet lamp tube 3 can also directly irradiate the ultraviolet light to the first disinfection chamber 11 and the second disinfection chamber 12. Thus, when the ultraviolet lamp tube 3 is in the second angular state, the ultraviolet light, hot air and ozone can be used for disinfecting tableware in the first disinfection chamber 11 and the second disinfection chamber 12 at the same time.

[0054] See Figure 9 and Figure 11, when the ultraviolet lamp tube 3 is in the fourth angular state, the flow guide block 4 blocks the first air outlet 21. Therefore, the hot air cannot flow out from the first air outlet 21. At the same time, the ultraviolet lamp tube 3 is in the off state, so the ultraviolet lamp tube 3 does not generate ozone and does not perform ultraviolet disinfection on the first disinfection chamber 11 and the second disinfection chamber 12. On the other hand, due to the avoidance of the flow guide block 4 for the second air outlet 22, the third air outlet 23 and the reflecting surface 51, the first disinfection chamber 11 and the second disinfection chamber 12 can communicate through the second air outlet 22 and the third air outlet 23. A circulation air outlet is provided on the side wall of the first disinfection chamber 11, and the circulation air outlet is communicated with the first air duct. The fan can continuously draw air at the circulation air outlet to continuously suck the air in the first disinfection chamber 11 into the first air duct. At the same time, the air in the second disinfection chamber 12 can also continuously enter the first disinfection chamber 11 through the second air outlet 22 and the third air outlet 23 and then be sucked into the first air duct. Since the first air outlet 21 is blocked, the air sucked into the first air duct will continuously accumulate, increasing the air pressure in the first air duct. Refer to Figure 1 , Figure 9 and Figure 10 , the disinfection cabinet further includes a flow guide plate 6. The flow guide plate 6 is installed on the first partition plate 2 and is located outside the first disinfection chamber 11 and the second disinfection chamber 12. A second air duct 61 is provided inside the flow guide plate 6. The circulation air outlet and the first air duct are respectively communicated with both ends of the second air duct 61. An air discharge port 62 communicated with the second air duct 61 is further provided on the flow guide plate 6. A cover plate 63 is provided at the air discharge port 62, and an elastic member 64 is provided between the cover plate 63 and the inner wall of the second air duct 61. In the non-deformed state of the elastic member 64, the cover plate 63 can block the air discharge port 62 to allow the air in the first air duct and the second air duct 61 to continuously accumulate and increase the air pressure. When the air pressure in the second air duct 61 reaches a certain level, the cover plate 63 can be pushed away from the air discharge port 62, so that the air in the second air duct 61 is discharged outside the cabinet body 1. Since the air in the second air duct 61 has a high humidity (mixed with the water vapor evaporated from the drying of tableware), the humidity inside the cabinet body 1 can continuously decrease as the air in the second air duct 61 is discharged outside the cabinet body 1.

[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0056] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
