no. 1 Embodiment

[0033] Figure 3a , Figure 3b This is the first embodiment of the flow path providing case used in the present invention. As shown in the figure, the first embodiment of the flow path providing housing 240 of the present invention includes: a first housing body 241 with an upper / lower opening; a main air inlet A is formed in the center of the upper surface, and an air inflow pipe is formed at the edge. B, and the first cover 242 that is press-fitted to the outer peripheral surface of the first housing main body 241 and rotates in the circumferential direction.

[0034] In the flow path providing case 240-1 having the above structure, the position of the first cover 242 is manually adjusted so that the air inflow tube B is positioned corresponding to the heating element. Then, after the adjustment process is completed, pressure is applied to couple the first cover 242 and the outer peripheral surface of the first case main body 241 . If fine adjustment is required, the firs...

no. 2 Embodiment

[0037] Figure 4a , Figure 4b This is the second embodiment of the flow path providing housing 240 used in the present invention. As shown in the figure, the second embodiment of the flow path providing housing of the present invention includes: a second housing main body 243 having a cylindrical shape with open upper and lower surfaces and a circular groove E formed on the upper surface; The air flow port C and the air inflow pipe D are respectively formed through the center and the edge, and in order to be pressed into the groove E formed in the second housing main body 243, a second circular protrusion is formed along the edge. 2 cover 244.

[0038] In the flow passage providing case 240-2 in the second embodiment as described above, the main air passage entry portion C and the air inflow pipe D are respectively penetratingly formed at the center and edge of the upper surface. The second cover 244, which protrudes in the circumferential direction along its edge, is adju...

Abstract

The invention discloses a heat sink of vacuum dust collector comprising a printed circuit board and a motor part each of which has a through v and a containing hatch along the central axis and they are connected via the sealing component; a heat emission plate whose center has a air transmission hatch connected to the heating element adhered on the printed circuit board while said plate can cover the printed circuit board and the motor part; and a flow-circuit support housing covering the heat emission plate, while it has a air inlet on its upper part to form the main air flow circuit and a air inlet pipe on the edge of upper part to support the bypass flow circuit which via the upper part of heating element to the main air flow circuit. The invention transfers the sucked air via the bypass flow circuit to the heating element, to guide the air flowing into the main air flow circuit. Therefore, it can improve the heat emission effect most of heating element with least effect on the resistance loss and the suction rate of main air flow circuit.

Description

technical field [0001] The present invention relates to a vacuum cleaner. In particular, it relates to a vacuum cleaner that maximizes the heat release effect of the heating element attached to the printed circuit board while having the least influence on the resistance loss and suction rate of the main air flow path of the vacuum cleaner. heat device. Background technique [0002] Generally speaking, a vacuum cleaner is a product that uses the drive of the motor, the printed circuit board and the heating element attached to the printed circuit board to inhale the dust on the indoor floor, then filters out the dust, and then discharges the clean air into the room again. Here, the work of discharging the heat generated by the motor or the heating element attached to the printed circuit board to the outside is a very important part of the vacuum cleaner. figure 1 Shown in is the heat release device that this vacuum cleaner mainly uses. [0003] figure 1 It is a schematic c...
