Description

Technical Field

[0001] This utility model relates to the field of air handling equipment technology, and in particular to a commercial kitchen air purification and cooling machine. Background Technology

[0002] In the field of air handling equipment technology, commercial kitchens, due to high-frequency cooking operations, continuously generate a large amount of oil fumes, odors, harmful gases, and heat. Commercial kitchen air purification and cooling machines, with their innovative design, integrate multiple functional modules such as pre-filtration, electrostatic adsorption, heat exchange cooling, and activated carbon adsorption. They can efficiently remove oil fume particles, adsorb odors and harmful gases, and simultaneously cool the environment. Therefore, there is a particular need for a commercial kitchen air purification and cooling machine.

[0003] However, existing commercial kitchen air purifiers and cooling machines often have complex filter disassembly structures that require multiple tools or cumbersome steps to disassemble. During breaks in high-intensity kitchen work, it is difficult for staff to find time to clean the filters in a timely manner, which leads to filter blockage over time and a significant decrease in purification efficiency. On the other hand, the existing filters are relatively large and difficult to clean thoroughly due to the size of the sink, further increasing the difficulty and cost of maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a commercial kitchen air purification and cooling machine to solve the problem mentioned in the background art. The filter disassembly structure of the existing commercial kitchen air purification and cooling machine is often designed to be complex, requiring multiple tools or cumbersome steps to complete the disassembly. During the high-intensity work in the kitchen, it is difficult for staff to take the time to clean the filter in a timely manner. Over time, the filter becomes clogged, and the purification efficiency drops significantly. On the other hand, the existing filter is large in size, and it is difficult to clean it thoroughly due to the size of the sink, which further aggravates the problems of maintenance difficulty and cost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a commercial kitchen air purification and cooling machine, comprising a shell, a base plate fixedly connected to the lower surface of the shell, a pulley fixedly connected to the lower surface of the base plate, a heat dissipation vent on one side surface of the shell, a back plate fixedly connected to one side surface of the shell, a handle fixedly connected to one side surface of the back plate, a fan fixedly connected to the inner surface of the shell, fins fixedly connected to the inner surface of the shell, a square groove on one side surface of the shell, a sliding groove on one side surface of the shell, and a disassembly and assembly mechanism provided on the inner surface of the sliding groove;

[0006] The disassembly and assembly mechanism includes a first filter screen, which is slidably connected to the inner surface of a sliding groove. A protrusion is fixedly connected to one side surface of the first filter screen. A second filter screen is slidably connected to one side surface of the first filter screen. A slot is formed on one side surface of the second filter screen. An active component is slidably connected to one side surface of the second filter screen. A passive component is slidably connected to one side surface of the active component. A pull rod is fixedly connected to one side surface of the passive component. A guide rod is fixedly connected to one side surface of the passive component. A spring is slidably connected to the outer surface of the guide rod. A fixing plate is slidably connected to the outer surface of the guide rod. A first circular hole and a second circular hole are formed on one side surface of the fixing plate.

[0007] Preferably, the fins are provided in multiples of the same size and are arranged at equal distances along the side surface of the base plate away from the pulley, and the inner surface of the square groove is rotatably connected to the driving member.

[0008] Preferably, the heat dissipation vents are provided in multiples of the same size and are symmetrically arranged along both sides of the outer shell, the handles are distributed in parallel with the back plate, and a fixing plate is fixedly connected to the inner surface of the square groove.

[0009] Preferably, the inner wall dimensions of the sliding groove match the outer wall dimensions of the second filter screen and the first filter screen, and the second filter screen and the first filter screen are distributed in parallel.

[0010] Preferably, the outer wall size of the protrusion matches the outer wall size of the slot, and the end of the passive component away from the guide rod is designed as a right-angled trapezoid, which is adapted to the outer wall size of the end of the active component away from the bottom plate.

[0011] Preferably, the guide rod and the spring are provided in two identical sizes and are distributed parallel to the pull rod, and the vertical horizontal center line of the pull rod intersects the horizontal horizontal center line of the driven member perpendicularly.

[0012] Preferably, there are two identical second circular holes, which match the outer wall size of the guide rod, and the inner wall size of the first circular hole matches the outer wall size of the pull rod.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This commercial kitchen air purification and cooling machine, through the setting of the disassembly and assembly mechanism, allows the operator to simply pull the lever. The cooperation of the fixed plate, passive component, spring, and guide rod instantly releases the locking force, and the active and passive components immediately unlock the filter screen. It is simple and quick. During installation, rotating the active component allows the elastic potential energy of the spring to precisely drive the components to engage, firmly locking the filter screen. The entire operation is simple and smooth. At the same time, the design of pulling the filter screen out along the sliding groove makes it convenient for the operator to separate it. The design of splitting the filter screen in two separates the original filter screen into two appropriately sized components. Whether soaking and washing it in a water tank or rinsing it with a high-pressure water gun, it can ensure that every pore of the filter screen is thoroughly cleaned, greatly improving the cleaning efficiency and cleanliness, and laying a solid foundation for the continuous and efficient operation of the equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5This utility model provides a technical solution: a commercial kitchen air purification and cooling machine, including a shell 1, a base plate 2 fixedly connected to the lower surface of the shell 1, a pulley 3 fixedly connected to the lower surface of the base plate 2, a heat dissipation vent 4 opened on one side surface of the shell 1, a back plate 5 fixedly connected to one side surface of the shell 1, a handle 6 fixedly connected to one side surface of the back plate 5, a fan 7 fixedly connected to the inner surface of the shell 1, fins 8 fixedly connected to the inner surface of the shell 1, a square groove 9 opened on one side surface of the shell 1, a sliding groove 10 opened on one side surface of the shell 1, and a disassembly and assembly mechanism 11 provided on the inner surface of the sliding groove 10;

[0022] The disassembly and assembly mechanism 11 includes a first filter screen 1101, which is slidably connected to the inner surface of the sliding groove 10. A protrusion 1102 is fixedly connected to one side surface of the first filter screen 1101. A second filter screen 1103 is slidably connected to one side surface of the first filter screen 1101. A groove 1104 is formed on one side surface of the second filter screen 1103. An active member 1105 is slidably connected to one side surface of the second filter screen 1103. A passive member 1106 is slidably connected to one side surface of the active member 1105. A fixed member 1106 is fixedly connected to one side surface of the passive member 1106. A pull rod 1107 and a guide rod 1108 are fixedly connected to one side surface of the passive component 1106. A spring 1109 is slidably connected to the outer surface of the guide rod 1108. A fixing plate 1110 is slidably connected to the outer surface of the guide rod 1108. A first circular hole 1111 and a second circular hole 1112 are opened on one side surface of the fixing plate 1110. The assembly and disassembly mechanism 11, the first filter screen 1101, the protrusion 1102, the second filter screen 1103, the slot 1104, the active component 1105, the passive component 1106, and the pull rod are all connected. The arrangement of components 1107, 1108, 1109, 1110, the first circular hole 1111, and the second circular hole 1112 allows for the following operation: Pulling the pull rod 1107 causes the passive component 1106 to slide along the guide rod 1108. Simultaneously, the passive component 1106 and the fixed plate 1110 compress the spring 1109, disengaging the passive component 1106 from the active component 1105. This allows the second filter screen 1103 to easily separate from the first filter screen 1101. Then, the second filter screen 1103 and the first filter screen 1101 are moved along the guide rod 1108. The movable groove 10 is pulled out to disassemble the filter screens and clean them separately. After cleaning, the second filter screen 1103 and the first filter screen 1101 are slid along the sliding groove 10, while the protrusion 1102 is made to fit with the groove 1104 to complete the pre-fixation. Then, by rotating the active part 1105 to fit with the passive part 1106, the second filter screen 1103 and the first filter screen 1101 are fixed. No professional tools or complicated operations are required. Ordinary workers can complete the disassembly and installation of the filter screens by themselves after simple training, which effectively reduces the time required to clean the filter screens.

[0023] Furthermore, multiple fins 8 of the same size are arranged at equal intervals along the side surface of the base plate 2 away from the pulley 3. The inner surface of the square groove 9 is rotatably connected to the active component 1105. Through the arrangement of the fins 8, the heat dissipation area is increased during use, effectively absorbing heat, and then dissipating the heat through the heat dissipation port 4. Multiple fins 8 arranged at equal intervals form a dense heat dissipation matrix. Compared with a single fin or sparse layout, it can contact the air more evenly and quickly absorb the heat generated by the operation of the fan 7 as well as the heat carried by the high-temperature oil fume air.

[0024] Furthermore, multiple heat dissipation vents 4 of the same size are provided and symmetrically arranged along both sides of the outer shell 1. The handle 6 is parallel to the back plate 5. A fixing plate 1110 is fixedly connected to the inner surface of the square groove 9. Through the arrangement of heat dissipation vents 4, the internal heat is dispersed during use. The multiple symmetrically arranged heat dissipation vents 4 form an effective air convection circulation, reducing the accumulation of heat inside the equipment and ensuring that the internal core components are always in a stable operating temperature range.

[0025] Furthermore, the inner wall dimensions of the sliding groove 10 match the outer wall dimensions of the second filter screen 1103 and the first filter screen 1101. The second filter screen 1103 and the first filter screen 1101 are distributed in parallel. By setting the second filter screen 1103 and the first filter screen 1101, when in use, the combination of the second filter screen 1103 and the first filter screen 1101 can effectively reduce the entry of oil stains into the interior. Dividing the filter screen into two makes it easier to soak in the water tank and to clean it later.

[0026] Furthermore, the outer wall dimensions of the protrusion 1102 match the outer wall dimensions of the slot 1104. The end of the passive member 1106 away from the guide rod 1108 is designed as a right-angled trapezoid and is adapted to the outer wall dimensions of the end of the active member 1105 away from the bottom plate 2. Through the setting of the protrusion 1102 and the slot 1104, after the second filter screen 1103 and the first filter screen 1101 enter the sliding groove 10, the protrusion 1102 simultaneously restricts the slot 1104, effectively improving the stability of the second filter screen 1103 and the first filter screen 1101.

[0027] Furthermore, two guide rods 1108 and springs 1109 of the same size are provided and are distributed parallel to the pull rod 1107. The vertical center line of the pull rod 1107 intersects the horizontal center line of the driven member 1106 perpendicularly. Through the arrangement of guide rods 1108 and springs 1109, the parallel distribution of guide rods 1108 provides stable guidance for the sliding of driven member 1106 and springs 1109 during use, ensuring that they will not deviate or shake during the sliding process, thus extending the service life of the mechanism.

[0028] Furthermore, two identical second circular holes 1112 are provided, and they match the outer wall dimensions of the guide rod 1108. The inner wall dimensions of the first circular hole 1111 match the outer wall dimensions of the pull rod 1107. Through the arrangement of the second circular hole 1112, the pull rod 1107, the guide rod 1108, and the first circular hole 1111, during use, the pull rod 1107 slides along the first circular hole 1111, while the guide rod 1108 slides along the second circular hole 1112, effectively positioning the driven component 1106 and the spring 1109, reducing mechanism failures.

[0029] Working Principle: When the air environment of a commercial kitchen needs improvement, the pulley 3 is moved by pulling the handle 6. Once it reaches the appropriate position, the kitchen begins to operate. The high-temperature oily smoke in the commercial kitchen enters the outer casing 1 under the action of the fan 7. The fan 7 generates suction, driving airflow. The fins 8 increase the heat dissipation area, effectively absorbing heat. Together with the heat dissipation vents 4, the heat is dissipated, achieving air cooling. When the first filter 1101 and the second filter 1103 accumulate too much oil, they are disassembled and cleaned through the disassembly mechanism 11. By pulling the lever 1107, the driven component 1106 slides along the guide rod 1108. At the same time, the driven component 1106 and the fixed plate 1110 interact with the spring 110. 9. Compression is performed, and the cooperation between the passive component 1106 and the active component 1105 is released. At this time, the second filter 1103 can be easily separated from the first filter 1101. Then, the second filter 1103 and the first filter 1101 are pulled out along the sliding groove 10 to complete the disassembly of the filters. They are then cleaned separately. After cleaning, the second filter 1103 and the first filter 1101 are slid along the sliding groove 10, while the protrusion 1102 is attached to the groove 1104 to complete the pre-fixation. Then, by rotating the active component 1105, it is attached to the passive component 1106, and the second filter 1103 and the first filter 1101 are fixed. This completes the use process of a commercial kitchen air purification and cooling machine.
