[0025] In the embodiment, when the drinking water machine works normally, drive motor 4 drives fan blade 7 to rotate, and the heat inside is discharged through the lower ventilation frame 2, and the cold air outside enters the case 1 through the upper ventilation frame 2, so that the air in the case 1 is stably circulated, and in the process, the dust on the filter plate 10 in the air inlet state gradually increases, when the dust reaches a certain weight, the directional positioning mechanism is moved to one side of the drive motor 4 through the monitoring assembly, so that when the drive motor 4 rotates, it moves upward along the limiting plate 3, so as to switch the air inlet and outlet position of the case 1, and at the same time, the reciprocating lead screw 27 is driven to rotate through the linkage mechanism in the corresponding direction, and the scraper 30 is driven to reciprocate along the surface of the filter plate 10, so as to clean the dust on the surface of the filter plate 10; when the dust on the lower filter plate 10 reaches a certain amount, the directional positioning mechanism is removed from the positioning of the drive motor 4, and the drive motor 4 moves to the lower part under the action of gravity, and the above process is repeated, so as to ensure the stability of air flow, thereby improving the heat dissipation efficiency of the drinking water machine.

[0026] Referring to Figure 4 and Figure 8 The directional positioning mechanism includes the mounting groove 13 arranged on the side of the limiting plate 3 close to the drive gear 17, the movable toothed plate 14 slidably connected in the mounting groove 13, the first electromagnetic plate 15 fixedly connected in the mounting groove 13, and a plurality of second springs 16 fixedly connected between the first electromagnetic plate 15 and the movable toothed plate 14, wherein the first electromagnetic plate 15 has magnetic properties when energized, and the magnetic properties of the side of the first electromagnetic plate 15 close to the movable toothed plate 14 are the same.

[0027] In this embodiment, when the dust on the upper filter plate 10 reaches a certain amount, the first electromagnetic plate 15 is powered on to drive the movable toothed plate 14 to move to the side of the drive gear 17. When the drive gear 17 is engaged with the movable toothed plate 14, the drive motor 4 drives the drive gear 17 to rotate, which drives the drive motor 4 to move upward along the limiting plate 3, thereby adjusting the position of the drive motor 4 to facilitate heat dissipation at different positions of the cabinet 1. After the first electromagnetic plate 15 is powered off, the movable toothed plate 14 returns to the mounting groove 13 under the action of the second spring 16.

[0028] Referring to Figure 4 and Figure 9 , further comprising a plurality of clamping grooves 18 formed on the side of the limiting plate 3 close to the drive motor 4, a horizontal groove 19 is formed on the side of the drive motor 4 close to the clamping groove 18, a clamping block 20 matched with the clamping groove 18 is slidably connected inside the horizontal groove 19, a second electromagnetic plate 21 is fixedly connected to the side of the horizontal groove 19 away from the clamping groove 18, a third spring 22 is fixedly connected between the second electromagnetic plate 21 and the clamping block 20, wherein the limiting plate 3 is provided with a sliding groove 5 on the side close to the drive motor 4, a limiting strip 6 matched with the sliding groove 5 is fixedly connected to the drive motor 4, the horizontal groove 19 penetrates the limiting strip 6, the second electromagnetic plate 21 is magnetized when powered on, and the magnetism on the sides close to each other of the second electromagnetic plate 21 and the clamping block 20 is opposite.

[0029] In this embodiment, when the drive motor 4 moves, the second electromagnetic plate 21 is powered on to drive the clamping block 20 to be received in the horizontal groove 19, so as to facilitate the movement of the drive motor 4. When the position adjustment of the drive motor 4 is completed, the second electromagnetic plate 21 is powered off, and the third spring 22 drives the clamping block 20 to move into the clamping groove 18, thereby positioning the drive motor 4 and ensuring the stable operation of the drive motor 4.

[0030] Referring to Figure 5 and Figure 10 , the monitoring assembly comprises a recess 9 formed on the ventilation frame 2, the filter plate 10 is slidably connected inside the recess 9, a first spring 11 is fixedly connected between the bottom of the recess 9 and the filter plate 10, a control switch 12 is fixedly connected to the bottom of the recess 9 and sleeved on the first spring 11, wherein the control switch 12 on the upper ventilation frame 2 is electrically connected between the first electromagnetic plate 15 and the second electromagnetic plate 21, and the control switch 12 on the lower ventilation frame 2 is electrically connected between the second electromagnetic plate 21.

[0031] In this embodiment, during the operation of the water dispenser, dust in the external air flows to the filter plate 10 in the air inlet state along the gas flow and is intercepted on the filter plate 10. As the weight of the dust on the filter plate 10 increases, the filter plate 10 gradually moves downward along the recess 9. When the weight of the dust reaches a certain amount, the bottom of the filter plate 10 contacts the control switch 12, thereby causing the first electromagnetic plate 15 or the second electromagnetic plate 21 to be powered on.

It should be explained that the inside of the sliding block 29 is provided with a protrusion matched with the reciprocating lead screw 27, and when the sliding block 29 moves, one side is attached to the inner wall of the cabinet 1, which limits the sliding block 29.

[0034] With reference to Figure 6 , the positioning hole 8 is provided on the ventilation frame 2 and matched with the output end of the driving motor 4, and a through hole is provided between the ventilation frames 2 on the same side and matched with the fan blade 7.

[0035] In this embodiment, the positioning hole 8 can ensure the stability of the moving position of the driving motor 4, and the through hole can avoid the collision between the fan blade 7 and the ventilation frame 2 during movement.

[0036] With reference to Figures 5-6 , the elastic cylinder 31 is fixedly connected to the inner wall of the cabinet 1, and when the sliding block 29 moves along the reciprocating lead screw 27 to one side of the elastic cylinder 31, the elastic cylinder 31 is compressed, a plurality of knocking rods 32 are fixedly connected to the side wall of the cabinet 1, and the knocking rods 32 are connected in communication with the elastic cylinder 31 through a pipeline.

[0037] In this embodiment, when the sliding block 29 moves along the reciprocating lead screw 27, the elastic cylinder 31 is intermittently compressed, and the gas in the elastic cylinder 31 is delivered to the knocking rod 32, so as to drive the knocking rod 32 to extend to the filter plate 10 and knock the filter plate 10, thereby improving the cleaning effect of the dust on the filter plate 10. When the sliding block 29 is separated from the elastic cylinder 31, the knocking rod 32 is retracted to avoid affecting the movement of the scraper 30.

[0038] With reference to Figures 1-2Also included is a ventilation hole 33 formed in the side wall of the cabinet 1 near the side of the filter plate 10, the ventilation hole 33 is inclined, for making the air in the cabinet 1 flow along the outer wall of the cabinet 1 to the side of the receiving groove 34.

[0039] In this embodiment, when the ventilation frame 2 ventilates, due to the small gap between the cabinet 1 and the cabinet or sideboard, the heat in the cabinet 1 can be discharged to the outside along with the gas flow, and the air in the external environment can also enter the cabinet 1 through the gap, thereby realizing the circulation of the air in the cabinet 1, and the cleaned dust can also be discharged to the outside of the cabinet or sideboard along with the air flow, wherein it needs to be explained that the inside of the cabinet 1 also includes the equipment required for water purifying, heating and refrigeration of the water dispenser, which is a conventional means in the prior art, and therefore will not be described.

[0040] Embodiment two: A heat dissipation method of an embedded water dispenser, comprising the following steps: Step one: when the equipment is working normally, heat dissipation is realized through the upper or lower part of the outer wall of the equipment, and air enters through the lower or upper part of the outer wall of the equipment; Step two: during the working process, the weight of the dust accumulated at the air inlet position is monitored; Step three: when the dust accumulated at the air inlet position reaches a threshold value, the air inlet and air outlet positions of the equipment are adjusted; Step four: at the same time, the dust accumulated at the air inlet position before adjustment is cleaned, and the cleaned dust flows to the outside along with the gas.
