Description

Technical Field

[0001] The utility model belongs to the technical field of air curtain machines, and particularly relates to a self-cleaning air curtain machine. Background Technique

[0002] An air curtain machine is an air purification device that blows out the high-temperature heat generated on the surface of a heater (the heater is composed of several PTC ceramic chips) through a powerful air flow generated by a high-speed motor driving a cross-flow or centrifugal air wheel, so as to form a heat-bearing curtain of air, and is widely used in shopping malls, supermarkets, hotels, restaurants, warehouses, factories, logistics centers and other places to create a more comfortable and healthy environment for people's life and work.

[0003] At present, there are various styles of air curtain machines on the market, and generally a structure of arranging multiple circles of heating fins along the axial direction on the outer surface of the heating pipe is adopted, and the contact area with the surrounding environment is increased through the heating fins wound outside the heating pipe, so that heat can be transferred to the air more quickly. However, since there are many floating dust particles in the air, and these particles will accumulate on the surface of the filter screen arranged outside the heating fins in the air curtain machine during the operation of the air curtain machine, and then the air circulation volume in the air curtain machine is affected after being used for a period of time. Therefore, during the use of the air curtain machine, it is necessary for the staff to clean or replace it regularly to extend the service life of the air curtain machine.

[0004] However, since the existing air curtain machine lacks a cleaning structure itself, and it is generally hung at a high place, during its actual use, it often requires the staff to perform high-altitude operations, which not only results in a large labor intensity but also has a certain risk factor in the whole operation process. Summary of the Utility Model

[0005] The technical problem solved by the utility model is to provide a self-cleaning air curtain machine with a cleaning function, which can reciprocally clean the filter screen in the air curtain machine to ensure the cleanliness and stability of the filter screen, improve the service life of the whole air curtain machine; and at the same time reduce the workload of the staff.

[0006] To solve the above technical problems, the technical solution provided by the present utility model is as follows: a self-cleaning hot air curtain machine, which includes a machine shell. A heating component is installed in the inner cavity of the machine shell. A filter screen is arranged on the air inlet side of the heating component. A support frame is arranged on the air inlet side of the filter screen. The upper and lower ends of the support frame are fixedly connected to the inner wall of the machine shell. A vertical linear module is arranged at each of the left and right ends of the support frame. A horizontal connecting plate is connected between the power output ends of the two vertical linear modules. A horizontal linear module is installed on the horizontal connecting plate. The controller of the horizontal linear module and the controllers of the two vertical linear modules are communicatively connected to a remote control switch. The power output end of the horizontal linear module is installed with a horizontal sliding plate. A dust suction nozzle is arranged on the side of the horizontal sliding plate facing the filter screen. A cleaning brush is arranged inside the dust suction nozzle. The air outlet end of the dust suction nozzle is connected to a dust suction machine through a dust suction hose. The dust suction machine is installed on the side of the horizontal sliding plate or the horizontal connecting plate away from the filter screen. After the present utility model is used for a period of time, the vertical linear module and the horizontal linear module can be controlled to move in the corresponding directions by operating the remote control switch to control the horizontal and vertical movement of the cleaning brush, so as to clean the filter screen, without the need for staff to perform high-altitude cleaning operations; moreover, the dust and the like generated during the cleaning process can be directly sucked into the dust suction machine through the dust suction nozzle, avoiding secondary pollution to the inner wall of the machine shell.

[0007] Further, the vertical linear module includes a vertical lead screw and a vertical guide rod. The two ends of the vertical lead screw are respectively rotatably installed on the support frame through an upper bearing seat and a lower bearing seat, and one end of the vertical lead screw is drivingly connected to a vertical driving motor. A vertical nut seat is threadedly connected to the middle of the vertical lead screw. The vertical nut seat is connected to one end of the horizontal connecting plate through a fastener; the two ends of the vertical guide rod are respectively fixedly installed on the support frame through an upper connecting seat and a lower connecting seat, and the middle of the vertical guide rod is vertically slidably connected to the horizontal connecting plate. In this way, the present utility model can control the up and down movement of the horizontal connecting plate through the cooperation between the vertical guide rod and the horizontal connecting plate, and the rotation of the vertical lead screw.

[0008] Further, the horizontal linear module includes a horizontal lead screw and a horizontal guide rod. The two ends of the horizontal lead screw are respectively rotatably installed on the horizontal connecting plate through a left bearing seat and a right bearing seat, and one end of the horizontal lead screw is drivingly connected to a horizontal driving motor. A horizontal nut seat is threadedly connected to the middle of the horizontal lead screw. The horizontal nut seat is connected to the horizontal sliding plate through a fastener; the two ends of the horizontal guide rod are respectively fixedly installed on the horizontal connecting plate through a left connecting seat and a right connecting seat, and the middle of the horizontal guide rod is horizontally slidably connected to the horizontal sliding plate along the length direction of the filter screen. In this way, the present utility model can control the movement of the horizontal connecting plate along the length direction of the filter screen through the cooperation between the horizontal guide rod and the horizontal connecting plate, and the rotation of the horizontal lead screw.

[0009] Further, the horizontal driving motor and the vertical driving motor are servo motors.

[0010] Further, an electric telescopic rod is installed on one side of the horizontal sliding plate facing the filter screen. The telescopic direction of the electric telescopic rod is the horizontal direction perpendicular to the filter screen, and the suction nozzle and the cleaning brush are installed at the power output end of the electric telescopic rod and can approach or move away from the filter screen under the action of the electric telescopic rod.

[0011] Further, an air inlet is provided at the top or side wall of the housing, and a blower is installed at the air inlet; an air outlet is provided at the bottom of the housing. The air outlet and the air inlet are located on both sides of the heating component and are responsible for the corresponding air outlet and air inlet functions respectively.

[0012] From the above technical solutions, it can be seen that the present utility model has the following advantages: After the present utility model is used for a period of time, the vertical linear module and the horizontal linear module can be remotely controlled by a remote control to move in the corresponding directions to control the horizontal and up-and-down movement of the cleaning brush, so as to clean the filter screen and ensure that air can pass smoothly; moreover, during the entire cleaning process, there is no need for staff to perform high-altitude cleaning operations, thereby greatly reducing the labor intensity of the staff.
