Description of the invention: [Technical field to which the invention belongs] ′ It can have a filter at the suction port to remove dust attached to a filter or a protective net. The present invention relates to a kind of air supply device or dust on a fan of a protective net that can be easily removed. [Prior Art] Patent Document 1 describes an air-supplying unit x clothes unit, which cleans a lamp and an entrance by a conventional fan. It provides a warm air passage between the air intake on the front of the frame and the warm air outlet on the front. A pair of / claw fans are installed near the empty milk intake, and the indoor air is drawn from the air intake ^ k to Qifeng. Path, install a filter on the back of the convection fan on the back of the convection fan when changing the warm air and sending it from the warm air outlet to the warm room machine | tightly attached and movable brushes, when the filter is known The filter is cleaned by driving the driving element, and by reversing the convection fan, the dust attached to the filter, H is removed by the material and blown away by the wind of the convection fan. It is also known that the filter can be cleaned by inverting a fan in a heat treatment apparatus such as a dryer (see Patent Document 2). [Patent Document 1] Japanese Unexamined Patent Publication No. 8-2 1 0705 (Patent Application No. 1, Item 1) [Patent Document 2] Japanese Unexamined Patent Publication No. 5-1 26467 (Patent Application No. 1, Item 1) 】 [Invention 6 2148-6902-PF; Ahddub 200533869 [Problems to be solved by the invention] The suction port on the blower is similar to the filter or protection net on the right side of Fang Lusheng makeup, which can be attached to the night dust. ,, only, _ m, and the entrance, the bow is blocked. To deal with this situation, the working day ^ or protection net is usually removed and cleaned regularly. * ^^% ^ ^ When the Nuwa fan is not installed, if the mobile bracket is not installed, the points are too high and the α is too high, which results in heavy work or maintenance. If the T and k fans are installed in a place where regular maintenance is difficult, it will produce One lesson ^ Congtian * Difficulty will block the suction port due to the adhesion of dust, etc., resulting in the inability to supply air. Another problem is that: 扃 山 山 = ^ ^ hunting on the air blower that cleans the suction port by the reversing shaft fan, can not + this π β…, the dust in the central part of the fan can cause dust to remain on it. Furthermore, one of the problems of the porter is that after the dust adheres and passes through a period of time, the dust will be fixed on the filter or the protection net, and the result cannot be blown away. If an air supply device other than that described in Patent Document 1 is used, the suction port can be cleaned. However, the movable brush used to remove the dust on the filter must be installed as another device. Related topics. In addition, since the movable mechanism is used, maintenance of the brush itself is also a problem. In addition, in Patent Document 2, the reversal of the shaft fan needs to be enjoyed 'manually', so there is a problem that the operation is troublesome. In order to solve the above-mentioned problem, the present invention aims to obtain a blower device which can easily and automatically remove dust attached to a filter or a protector on a blower having a filter or a protector at a suction port. 7 2148-6902-PF; Ahddub 200533869 [Means to solve the problem] In order to solve the above-mentioned problem, the air supply device of the present invention includes: a box type; ', a suction port on the moon surface and an air supply port on the front side; a motor, It is set inside the box-shaped body and can rotate forward and reverse; shaft fan, which is installed on the rotating shaft of this motor; and a filter or protection net, which is installed on the suction inlet, which is characterized by: The device is provided with a switching device that can switch the rotation direction of the motor to the opposite direction on the control circuit of the motor and a time switch that can set the operating time of the switching device to reverse the above process within a certain 4 interval. Cleaner or protective net for dust cleaning. [Effect of the invention] With the invention, the dust attached to the filter or the protection net installed on the suction port can be reversed within a certain time interval before the dust attached to the filter is fixed, and the dust is blown away for cleaning and suction. Main cause of mouth blockage. In addition, even if the air supply device is installed at a high place, the filter or the protective net can be cleaned easily and automatically. Furthermore, since the air can be supplied well without clogging the filter or the protective net, the number of regular maintenance can be reduced, and the effect of reducing maintenance costs can be achieved. [Embodiment] An embodiment of the present invention will be described below with reference to the drawings. 2148-6902-PF; Ahddub 8 200533869 The first implementation type. The second figure is a cross-sectional view showing the inner state of the fan according to the first embodiment of the present invention. &Quot; " " " " Rear view of the air supply device: Fig. 3 is a top view of Fig. 2, and Fig. 4 is a front view of Fig. 2. In addition, Fig. 5 is a circuit diagram in the embodiment. The air supply device 10 is used as indoor air supply ^ For equipment cooling, it is installed by means of county cranes, floor or wall mounting. Air supply device !. Box-shaped body with a wounded six-sided box shape is set on the box-shaped body 1, and a suction port 2 is provided on the back. The outlet is 3 ° and the inside of the box type is divided according to the number of blowers. In the figure, the blower is ^, and in the second figure = the fan is 3σ. There is a 丨 blower on the right. In the box type The internally mounted motor 5 'in the body 丨 can rotate forward and reverse the shaft fan 4 installed inside the opening 6 and the rotary fan shaft 4' and then installed again-a common wire guide fluid is used to form the front air supply Port 3. Then, on the above suction port 2 'in order to prevent dust or foreign matter Enter the inside of the box k-type body 'to install a filter or a protective net 8. The air drawn in from the suction port 2 passes through the shaft fan * in the opening 6, and the air fluid 7' is supplied by the air supply η q / 10, " 3. For example, In the case of indoor air supply, 'brother * Κ' I I ^ Cj ίΛ? Φ: The floating dust in the second milk will adhere when passing through the filter f protection net 8 installed in the suction port 2, and it will be attached to the filter or the protection net. 8 on the stack. In particular, 'the more the amount of dust in the filter' or the protection net 8, the more if the blockage occurs in a short period of time. Using the air supply device in the case of continuous blockage will fully benefit the established air supply capacity. In addition, if the air supply device is installed at a high place, when removing the filter or the protection 2148-6902-PF; Ahddub 9 200533869, the protective net 8 needs to be installed with a movable support, so it becomes a very heavy work and It also becomes a dangerous operation. Therefore, high maintenance costs are also required. Therefore, in this embodiment, as shown in FIG. 5, the control circuit of the motor 5 is installed to switch the rotation direction of the motor 5 to Opposite party To the switching device 11 (such as a repeater switch) and the time switch 12 which can set the operating time of the switching device 9. The control circuit of the motor 5 can be set inside or outside the body. With this embodiment, when the The time switch 12 set on the time switch 2 turns on the time switch 12 and the switching device is switched from the position of the solid line shown in FIG. 5 to the position of the dotted line. As a result, the motor 5 is switched from the forward rotation state to the reverse rotation state. State, therefore, the air supply is instead going out from the suction port 2. The dust deposited on the transition device or the security compliance net 8 on the inlet 2 can be blown away and cleaned before fixing. For example, if By setting this reversal time outside of business hours, there is no problem of dust flying around. In addition, by setting an appropriate inversion time, it is possible to minimize the dust attached to the filter or the protective net 8. In addition, the time switch 12 is turned off after a predetermined reversal time, thereby the switch device 11 switches the motor 5 to the forward rotation (the solid line position in FIG. 5). With the construction of the above-mentioned air supply device 10, the cleaning operation produced by the clogging of the filter or the protective net 8 can be easily and automatically completed without removing the filter or the protective net. The second implementation mode. With this implementation mode off 12, the blower will only start to run in a certain period of time in the first implementation mode described above. The time will be turned on. 214 8-6902-PF ^ ddub 200533869 Cleaning function. Thereby, cleaning of the drone or the protective net 8 is performed without any problem even outside the operation time. The source can also be a third embodiment. With this embodiment, in the above-mentioned first embodiment, the ㈣ 'blower reverses the function of borrowing = on only during a certain period of time when the operation starts. Thereby, even if the electric pen is cut off outside the operating time, the cleaner or the protective net 8 can be cleaned without any problem. , ^ 4th implementation mode. With this implementation mode, in the above! The implementation type car is stepped on by the center of the fan 4 and the active central index is weak. Therefore, the front side of the car is targeted (from the center of the Rila Hirata phoenix fan ^ front side of the moon) The dust that cannot be blown away is installed in the filter P or the protective net 8 corresponding to the central part of the fan 4, the P position, and the circular plate 9 is installed. This can reduce the amount of dust attached to the vicinity of the central portion of the shaft fan 4. If the size of Yuanmin ~ Pole 9 is set too: "If the air supply capacity is lowered ', if it is set too small, dust, ash, or protection net 8 will accumulate, so' set the appropriate size is _ = point 0 to ensure air supply capacity In addition, the outer diameter of the circular plate 9 where dust does not accumulate on the filter or the protective net 8 is set to ㈣⑽ of the outer diameter of the shaft fan. In addition, in this embodiment, the above-mentioned first embodiment is implemented. t-type.., 5th implementation form. With this implementation form, in the above-mentioned implementation form, the air volume during reverse rotation is greater than that during forward rotation. In other words, when 'reverse rotation, motor 5 rotates' The number of times is 2148-6902-PF; Ahddub 11 200533869 Second =: This method constitutes the control circuit. This can effectively clean the filter or the protective net 8 in a short time. 6th implementation type · With this embodiment, in the above-mentioned first embodiment, the function of adjusting the amount of airflow during reverse rotation is smaller than that during forward rotation, and the function of adjusting the symbol f.
