That is, the second ventilation hole 613 forms an auxiliary air inlet in the heating mode, the first ventilation hole 612 forms an auxiliary air inlet in the ventilation mode, and the space in the snail shell 800 below the top panel 611 of the frame 610 and the frame 610 The space inside the circuit board case 700 above the top panel 611 is connected to form The auxiliary air passage can ensure a sufficient volume of ventilation air passage even if the thickness of the frame 610 is reduced, thereby ensuring product air volume, reducing product volume, and saving cost. Also, since the wind can enter the circulating blower 310 and the ventilation blower 410 from the auxiliary air inlet, the wind speed of the air inlet (the main air inlet of the ventilation) below the circulating blower 310 and the ventilation blower 410 is reduced, and the fan speed can also be Reduced, so you can reduce product noise.

As shown in FIG. 6 , a third ventilation hole 614 communicating with the air passage 620 that communicates with the first ventilation hole 612 and the second ventilation hole 613 is disposed on the outer peripheral side of the snail shell 800 on the top panel 611 .

In the present embodiment, the heater combination is disposed above the mask air outlet 210, and the third ventilation hole 614 is disposed adjacent to the opposite side of the side of the frame 610 in which the heater combination is provided.

Through the third ventilation hole 614, an auxiliary air inlet in a ventilation mode, a heating mode, and a dry mode is formed, specifically:

As shown in FIG. 4, when the product is in the heating mode, the circulating blower 310 operates, the ventilation blower 410 does not operate, and a part of the indoor air enters through the air inlet 220 of the mask from the air inlet 311 (circulating the main air inlet) below the circulating blower 310. The circulating blower 310 is inside.

Since the third fan hole 614 is disposed on the top panel 611 above the circulation fan blade 330 and the ventilating fan blade 430, a part of the indoor air can pass through the mask air inlet 220 and enter the electrical component box 700 through the third vent hole 614. The space enters the circulating blower 310 through the first venting hole 612 above the circulating fan blade 330, and finally enters the heating combination with the air outlet 820 of the circulating blower 310 to form heated air, which is formed from the mask. The tuyere 210 is blown indoors.

As shown in FIG. 5, when the product is in the ventilation mode, the ventilation blower 410 operates, the circulating blower 310 does not operate, and a part of the indoor air passes through the air inlet 220 of the mask from the air inlet 411 below the ventilation blower 410 (ventilation main entrance) The tuyere) enters the ventilation blower 410.

Since the circulation fan blade 330 and the top panel 611 above the ventilation fan blade 43 are provided with the third ventilation hole 614, a part of the indoor air can pass through the mask air inlet 220 and enter the electrical component box 700 through the third ventilation hole 614. The space enters the ventilation blower 410 through the second ventilation hole 613 above the inside of the ventilation fan blade 430, and finally is discharged to the outside through the exhaust port 810 communicating with the outside.

Figure 6 is a schematic perspective view of the drying mode of the present invention. As shown, when the product is in the dry mode, the ventilation blower 410 and the circulating blower 310 are simultaneously operated, and a part of the indoor air passes through the air inlet 450 of the mask from the ventilation blower 410 and the air inlet 311 below the circulating blower 310 (recycling main entrance) The tuyere) and the air inlet 411 (ventilating main air inlet) enter the ventilation blower 410 and the circulating blower 310.

Because the third ventilation hole 614 is provided, a part of the indoor air can pass through the air inlet 220 of the mask, and enter the space inside the electrical component box 700 through the third ventilation hole 614. In this part of the air, a part of the air passes through the ventilation fan. The second venting hole 613 above the blade 430 enters the ventilating blower 410, and finally is discharged to the outside through the exhaust vent 810 communicating with the outside; and the other portion of the air passes through the first venting opening 610 of the upper portion of the circulating fan blade 330. Entering the circulation blower 310, finally entering the cycle The heating of the air outlets 820 of the blower 310 is combined to form heated air, which is blown into the room from the mask air outlet 210. That is, the third ventilation hole 614 forms an auxiliary air inlet in the ventilation mode, the heating mode, and the dry mode, and the space in the snail shell 800 below the top panel 611 and the space in the circuit board case 700 above the top panel 611 The communication is formed to form an auxiliary air passage, and even if the thickness of the frame 610 is reduced, a sufficient volume of ventilation air passage can be ensured to ensure the air volume of the product. Moreover, the wind speeds of the air inlet 311 (circulating main air inlet) and the air inlet 411 (venting main air inlet) under the circulating blower and the ventilation blower can be respectively reduced, thereby reducing the product volume and saving cost.

And the heater combination is disposed above the mask air outlet 210, the third ventilation hole 614 is disposed adjacent to the opposite side of the side of the frame 610 provided with the heater combination, and the air outlet 210 can be disposed to be sucked from the third ventilation hole 614 It is far away, so the air circulation in the bathroom will be more efficient in the heating mode and the dry mode. A short circuit between the air inlet 220 and the air outlet 210 can be easily prevented.

Figure 7 is a perspective view of the electrical component box cover with a portion of the artifact removed. As shown in FIG. 7, the air passage connecting the first ventilation hole 612, the second ventilation hole 613, and the third ventilation hole 614 is provided in the electrical component box 700 through the partition in the longitudinal direction of the electrical component box 700. 710 separates the second space 730 remaining after the first space 720 of the electrical component 740 is placed.

When the present invention is used in a bathroom, high-temperature and high-humidity air may enter the electrical component box 700 and condense on the electrical component 740 to form dew condensation water to damage the electrical component 740. Therefore, by providing the partition 710 that separates the electrical component 740 from the motors 320 and 420 in the electrical component box 700, even The air passes through the first ventilation hole 612, the second ventilation hole 613 and the third ventilation hole 614 on the top panel 611 of the frame 610 into the second space 730 of the electrical component box 700, and is also blocked by the partition 710, so that the air cannot enter. The first space 720 is in contact with the electrical component 740 to condense into dew condensation water.

And the partition plate 710 forms an inclined curved portion connecting the air passage between the first ventilation hole 612 and the second ventilation hole 613, that is, the partition plate 710 is obliquely bent in the direction away from the circulation motor 320 on the side of the first ventilation hole 612, so The first vent hole 612 side may be disposed wider than the second vent hole 613 side. Since the wind blown by the circulating blower 310 passes through the heater combination and the wind direction plate to be blown outdoors, it is necessary to ensure a sufficient amount of air in the heating mode. Since the first vent hole 612 side in communication with the circulation blower 310 can be disposed wider than the second vent hole 613 side, the first vent hole 612 can be set to be larger. When the product is in the heating mode, the wind enters the space in the electrical component box 700 from the second ventilation hole 613 and the third ventilation hole 614 which are smaller than the first ventilation hole 612, and then enters the circulation from the larger first ventilation hole 612. In the blower 310, this ensures a large circulation air path and ensures the air volume.

Further, as shown in FIG. 4, FIG. 5 and FIG. 6, the openings of the first ventilation hole 612 and the second ventilation hole 613 are preferably divided into two or more. Thus, even if the first ventilation hole 612 and the second ventilation hole 613 are provided in the outer peripheral portion of the motor, it is possible to reserve a space in which a structure (such as a screw hole or a riveted structure) for mounting the motor is provided. On the other hand, although it may be provided as an annular opening surrounding the motor, it is necessary to additionally prepare a bracket for fixing the motor and mount it on the outer peripheral side of the opening. The cost is higher than that of the first ventilation hole 612 and the second ventilation hole 613.

As shown in FIG. 7, the electrical component box 700 includes a base 760 and a cover 770, and a venting opening 771 is formed in the cover 770 of the first space 720 of the electrical component box 700. Therefore, even if a small portion of the air enters the first space 720 through the opening for wiring, it is discharged through the vent hole 771 without being condensed into dew condensation water. Thereby improving product safety.
