Description

Technical Field

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

[0002] The disinfection cabinet includes a cabinet body, a grid, and a heater. The grid is set inside the cabinet and separates the first disinfection chamber and the second disinfection chamber. The heater continuously heats the air inside the cabinet to dry and disinfect the tableware. The hollow structure of the grid allows heat to be transferred from the first disinfection chamber to the second disinfection chamber.

[0003] However, in actual use, there is a situation where tableware is placed in the first disinfection chamber but not in the second disinfection chamber. In this case, heat conduction in the second disinfection chamber is unnecessary because the heat will lose some energy in the second disinfection chamber, which will result in a waste of power of the heater and increase energy consumption.

[0004] Therefore, new solutions need to be proposed to solve this problem. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a disinfection cabinet to solve the above problems.

[0006] The present invention achieves the above-mentioned object through the following technical solutions: A disinfection cabinet comprises a cabinet body and a fixed grid and a movable grid arranged inside the cabinet body, wherein a first disinfection chamber is formed between the fixed grid and the cabinet body, and a second disinfection chamber is formed between the fixed grid and the movable grid; The fixed grid is provided with an air hole for connecting the first disinfection chamber and the second disinfection chamber, and the fixed grid is provided with a shielding member for covering the air hole. The shielding member is tilted and is kept in a state of covering the air hole by its own gravity in the absence of other external forces; The movable grid is rotatably arranged in the cabinet, and a transmission assembly is connected between the movable grid and the shielding member, so that the movable grid is pulled by the deadweight of the shielding member, so that the movable grid is in a raised state; When tableware is placed on the movable grid, the movable grid is displaced, generating a driving force to the shielding component through the transmission component, thereby opening the air holes.

[0007] The present invention is further configured as follows: the transmission assembly includes: Connecting rope 1, used for connecting with the shielding member; Connecting rope 2, used for connecting with the movable grid; A tension compensating member, used to enhance the pulling force for pulling the shielding member to overcome its own gravity, the tension compensating member being rotatably disposed within the cabinet; The connecting rope 1 and the connecting rope 2 are both connected to the tension compensation component, and the distance between the connection point of the connecting rope 1 and the rotation point of the tension compensation component itself is smaller than the distance between the connection point of the connecting rope 2 and the rotation point of the tension compensation component itself.

[0008] The present invention is further configured as follows: a rotating portion is rotatably connected to a side of the shielding member close to the fixed grid, and the rotating portion is embedded in the fixed grid and rotatably connected to the fixed grid; The rotating part is divided into a connecting end and a counterweight end at the rotating connection with the fixed grid. The connecting end is used to be rotatably connected to the shielding member. The weight of the counterweight end is greater than the weight of the connecting end, so as to guide the rotating part to rotate in the direction of pulling the shielding member to cover the air hole.

[0009] The present invention is further configured as follows: an avoidance cavity is provided at a position of the fixed grid corresponding to the rotating part for rotation of the rotating part, and a limiting side wall is provided at a position of the avoidance cavity corresponding to the counterweight end for limiting the rotation amplitude of the counterweight end to not exceed the rotating connection between the rotating part and the fixed grid.

[0010] The present invention is further configured such that: the fixed grid is arranged to be inclined, and the inclination direction is consistent with that of the shielding member.

[0011] The present invention is further configured such that the rotation connection point between the tension compensating member and the cabinet body is eccentrically arranged so that the second connecting rope pulls the tension compensating member to rotate and enhance the tension.

[0012] The present invention is further configured as follows: a plurality of movable grids are provided, and a plurality of disinfection chambers are formed between the movable grids. The movable grids are also provided with air holes and shielding members covering the air holes, and transmission components are also connected between them.

[0013] Compared with the prior art, the present invention has the following beneficial effects: First, through the load-sensing mechanism of the movable grid, the transmission component automatically opens the air holes when and only when tableware is placed in the disinfection chamber, connecting the first and second disinfection chambers. This design avoids the energy waste of heating the entire space of traditional disinfection cabinets. Secondly, the tension compensator achieves torque amplification through the lever arm ratio, allowing the shield to be reliably opened even with a small amount of tableware. The opening force threshold is reduced, ensuring stable opening during use. At the same time, the eccentric structure generates additional driving torque during rotation, effectively compensating for friction loss and further ensuring the stability of the transmission system in long-term use. Third, the design of the counterweight end of the rotating part creates a weight difference between the connecting end and the counterweight end, which generates a reset torque to ensure that the shielding member is reliably closed when there is no load.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0017] A disinfection cabinet, such as Figure 1-Figure 5 As shown, it includes a cabinet body 1, a cabinet door (not shown), and a fixed grid 2 and a movable grid 3 arranged inside the cabinet body 1. A first disinfection chamber is formed between the fixed grid 2 and the cabinet body 1, and a second disinfection chamber is formed between the fixed grid 2 and the movable grid 3. The fixed grid 2 is provided with air holes for connecting the first disinfection chamber and the second disinfection chamber. The heat generated by the heater can be quickly conducted to the second disinfection chamber through the air holes, thereby forming a good high-temperature sterilization effect.

[0018] like Figure 1-Figure 2 As shown, a shielding member 4 for covering the air holes is provided on the fixed grid 2. The shielding member 4 is tilted and is in a state of covering the air holes by its own gravity when not subject to other external forces. At the same time, a high-temperature resistant silicone sealing strip is embedded in the edge of the shielding member 4, so that the sealing formed by the shielding member 4 can be ensured when fitted, thereby ensuring that the first disinfection chamber and the second disinfection chamber are in a non-connected state.

[0019] And as Figure 2 As shown, the movable grid 3 is rotatably arranged in the cabinet 1, and a transmission assembly is connected between the movable grid 3 and the shielding member 4, so that the movable grid 3 is pulled by the deadweight of the shielding member 4, so that the movable grid 3 is in a raised state. When tableware is placed on the movable grid 3, the movable grid 3 is displaced, and a driving force is generated to the shielding member through the transmission assembly, opening the air holes, thereby achieving communication between the first disinfection chamber and the second disinfection chamber. Furthermore, the air holes between the disinfection chambers can be automatically opened or closed according to whether tableware is placed in different disinfection chambers, thereby reducing the energy consumption of the heater. The opening and closing of the shielding member 4 is achieved by the weight of the shielding member 4 and the tableware itself, thereby ensuring the stability of the transmission.

[0020] like Figure 2-Figure 3 As shown, the transmission assembly includes a connecting rope 1 5 for connecting to the shielding member 4, a connecting rope 2 6 for connecting to the movable grid 3, and a tension compensation member 7 for enhancing the pulling force of pulling the shielding member 4 to overcome its own gravity, wherein the tension compensation member 7 is rotatably arranged in the cabinet 1, and the connecting rope 1 5 and the connecting rope 2 6 are both connected to the tension compensation member 7, and the distance between the connection point of the connecting rope 1 5 and the rotation point of the tension compensation member 7 itself is smaller than the distance between the connection point of the connecting rope 2 6 and the rotation point of the tension compensation member 7 itself, thereby achieving different torques through different distances.

[0021] Derived by the torque amplification formula: Assume that the distance between the connection point P1 of the connecting rope 1 (5) and the rotation point O1 is L1 = 30mm; the distance between the connection point P2 of the connecting rope 2 (6) and the rotation point O1 is L2 = 60mm; Assume that the tension of the connecting rope 2 (6) is F2, and the tension of the connecting rope 1 (5) is F1; According to the lever balance condition: F1×L1=F2×L2; the torque amplification factor k=L2 / L1=2 (because L2=60mm, L1=30mm), that is, F1=2F2. In summary, it can be concluded that the connecting rope 2 6 only needs a relatively small force to pull the tension compensation member 7 to rotate, thereby effectively achieving the effect of enhancing the pulling force.

[0022] Connecting ropes 1 5 and 2 6 are made of stainless steel wire ropes, ensuring that they will not become loose due to stretching or friction over long periods of use, which could affect the precision of the linkage between shielding member 4 and movable grid 3. Furthermore, several guide wheels are provided within cabinet 1 to guide the pulling direction of connecting ropes 1 5 and 2 6, ensuring stability and continuity when connecting ropes 1 5 and 2 6 pull on tension compensation member 7.

[0023] And as Figure 3As shown, the rotation connection point between the tension compensator 7 and the cabinet 1 is eccentrically arranged. At the same time, when the shielding member 4 is in the shielding state, the tension compensator 7 itself is also in a balanced state. Therefore, according to the eccentric wheel drive principle, when the shielding member (4) is in the closed state, the center of gravity G of the tension compensator 7 is located directly below the rotation point O1 of the tension compensator 7. At this time, the gravity arm Lg=0, and the system is in stable equilibrium.

[0024] When the connecting rope 2 (6) applies a tension F2 to rotate the eccentric wheel by an angle θ: when the center of gravity G shifts to the primary side of point O1, the gravity arm Lg = e×sinθ (e is the eccentric distance).

[0025] The gravity G of the tension compensator 7 generates an additional torque Maddition=G×Lg, which has the same direction as the torque of the tension F2, and assists in driving the tension compensator 7 to rotate.

[0026] When θ=30°, Lg=20×sin30°=10mm. If G=0.5N, the additional torque Madd=0.5×10=5N·mm, which accounts for about 15% of the total driving torque.

[0027] Therefore, it can be concluded that when the connecting rope 2 6 pulls the tension compensation part 7 to rotate, the eccentric setting will form a driving force for rotation as the tension compensation part 7 rotates, thereby enhancing the tension of the connecting rope 2 6 when pulling the tension compensation part 7 to rotate, and thus ensuring that the shielding part 4 can be stably pulled to move.

[0028] At the same time Figure 3-Figure 5 As shown, the shielding member 4 is rotatably connected to a rotating portion 8 on one side close to the fixed grid 2. The rotating portion 8 is embedded in the fixed grid 2 and is rotatably connected to the fixed grid 2. The rotating portion 8 makes the movement trajectory of the shielding member 4 an arc track, thereby reducing the friction between the shielding member 4 and the fixed grid 2 and improving the sealing performance.

[0029] And as Figure 3 and Figure 5 As shown, the rotating part 8 is divided into a connecting end and a counterweight end at the rotating connection with the fixed grid 2. The connecting end is used to be rotatably connected to the shielding member 4. The weight of the counterweight end is greater than the weight of the connecting end, so as to guide the rotating part 8 to rotate in the direction of pulling the shielding member 4 to cover the air hole. In the absence of other external forces, the weight of the counterweight end can drive the shielding member 4 to cover the air hole by the rotating part 8, thereby providing a driving force for resetting the position of the shielding member 4.

[0030] At the same time Figure 3As shown, the fixed grid 2 is provided with an avoidance cavity 9 at the position corresponding to the rotating part 8, which is used for the rotation of the rotating part 8, and the avoidance cavity 9 is provided with a limiting side wall 10 at the position corresponding to the counterweight end, which is used to limit the rotation amplitude of the counterweight end to not exceed the rotating connection between the rotating part 8 and the fixed grid 2. The limiting side wall 10 is used to prevent the rotating part 8 from rotating beyond the stroke, thereby ensuring the transmission stability of the overall structure.

[0031] like Figure 1-Figure 2 As shown, the fixed grid 2 is tilted, and the tilting direction is consistent with the shielding member 4. The tilting setting allows the fixed grid 2 and the shielding member 4 to fit better.

[0032] like Figure 1-Figure 2 As shown, several movable grids 3 are provided, and several disinfection chambers are formed between the movable grids 3. The movable grids 3 are also provided with air holes and shielding members 4 covering the air holes, and transmission components are also connected between them. Therefore, when multiple movable grids 3 are installed to form multiple disinfection chambers, the orderly connection and closing of the multiple disinfection chambers can be ensured.

[0033] Among them Figure 2 As shown, the rotation angle of the tension compensation member 7 in the transmission assembly between the movable grids 3 will be greater than the rotation angle of the tension compensation member 7 in the transmission assembly between the fixed grid 2 and the movable grid 3, so as to compensate for the increase in the pulling distance required due to the rotation of the movable grid 3 located on the upper layer between the movable grids 3, thereby ensuring the overall transmission stability.

[0034] At the same time Figure 2 As shown, no shielding member 4 is provided on the bottom movable grid 3, thereby ensuring that the tableware placed on the bottom movable grid 3 and the contact surface of the movable grid 3 can also be in good contact with the hot air, ensuring the disinfection effect.

[0035] Working principle: The tableware that needs to be sterilized at high temperature is placed in order on the fixed grid 2 and the movable grid 3. When the tableware is placed on the movable grid 3, the weight of the tableware presses down the movable grid 3 to rotate, so that the movable grid 3 pulls the tension compensation part 7 to rotate through the connecting rope 2 6. The tension is enhanced by the tension compensation part 7, so that the tension compensation part 7 pulls the shielding part 4 in the oblique upward direction through the connecting rope 1 5, so that the shielding part 4 drives the rotating part 8 to move together, and then the rotating part 8 rotates, thereby pushing the shielding part 4 away from the air hole and forming a gap between it and the fixed grid 2.

[0036] After the high-temperature disinfection is complete and all the tableware on the movable grid 3 is removed, the counterweight end of the rotating portion 8 is pulled downward by gravity, which in turn drives the rotating portion 8 to rotate in the opposite direction, restoring the position of the shielding member 4 and thus covering the air hole. During the restoration of the shielding member 4, the tension compensation member 7 is moved to the position via the connecting rope 1 5, and the movable grid 3 is pulled back to the raised position by the connecting rope 2 6.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0038] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
