Description of the Invention: [Technical Field of the Invention] The present invention relates to a pipe cover and a pipe combination for a ventilating fan, and more particularly to a pipe cover and a pipe combination for entering and exiting a ventilating fan. 5 [Prior Art] As shown in Figure 1, it is a common combination of pipe cover and pipe at the inlet and outlet of the ventilation fan. Figure 2 is a schematic cross-sectional view thereof. The pipe cover 1 is composed of a front cover u ^ and a rear cover 12, and a horizontal baffle 21 is disposed inside the pipe 20 to form an air outlet pipe 23 and an air inlet pipe 22 below. Corresponding to the baffle 21, a horizontal partition plate 12A is also formed on the rear cover 12, and the space surrounded by the front cover u and the rear cover 12 is divided into an upper air outlet side 112 and a lower air inlet side 113, and formed. The inner air outlet 130 and the inner air inlet 140 are provided. An outlet tuyere 115 is formed above the front surface of the front cover, and an outer air inlet 114 is formed below. When the ventilating fan is in operation, the air discharged from the ventilating fan 15 enters the air outlet side 112 through the air outlet pipe 23 and the inner air outlet port 130, and is discharged to the outside through the air outlet port U5. At the same time, the air from the outdoor air inlet 114 is taken into the outdoor air inlet side 113 and the inner air inlet 14 . Through the inlet duct 22 to the inside of the ventilating fan: an air outlet passage and an air inlet passage which are vertically arranged vertically are formed. Since Renqi outlet 115 and external air inlet 114 are respectively located on the upper and lower sides of the front surface of the duct cover 20 10, they are affected by the wind blown from the front and the wind blown from the sky, so that the wind ση5 comes out. The air enters the air inlet U4 again, causing re-contamination. In addition, since the outlet tuyere 115 is located on the front side of the duct cover 1Q, and the switch curtains at the tuyere n4 and the outlet tuyere 115 are fixed structures, the rain 3 water foreign matter makes it easy to enter the duct cover from the outer air inlet 114 and the outlet tuyere, and then enters again. In the ventilation fan, it increases the safety hazard. In addition, it is often necessary to clean the inside of the pipe cover, so it is necessary to unload the front cover 1 often but there is no good engagement structure between the front cover and the rear cover 12. In addition, such a design does not take into account that the temperature of the exhausted air is usually greater than the temperature of the inhaled air, and there is no heat exchange in the entire structure, thus wasting energy. SUMMARY OF THE INVENTION The main object of the present invention is to provide a pipe cover and a pipe combination for a ventilating fan, which can effectively prevent the discharged air from entering the air inlet. A secondary object of the present invention is to provide a duct cover and a pipe for a ventilating fan, and 5, 旎 effectively improve the rainwater and foreign matter entering the pipe from the front side and facilitate the discharge of rainwater and foreign matter, thereby enhancing safety. Another secondary objective of the invention is to provide a combination of a pipe cover and a pipe for a ventilating fan, which facilitates the disassembly and installation of the pipe cover, facilitates cleaning work, and improves the service life of the product. ^ Another secondary objective of the invention is to provide a combination of a duct cover and a duct for a ventilating fan, which can fully utilize the exhausted air to heat the inhaled air and utilize energy efficiently. In order to achieve the above object, the present invention provides a pipe cover and a S-way combination for a ventilating fan, comprising a front cover, a rear cover and a pipe, wherein a baffle is vertically disposed in the pipe, and an air duct and an air inlet pipe are formed on the left and right; The baffle plate and the rear cover are vertically provided with a partition plate. The space enclosed by the front cover and the rear cover is divided into left and right sides! 37998 〇 wind outlet side and air inlet side 'The outer left and right sides of the rear cover are provided with an outlet vent and outer The air inlet has an inner air outlet and an inner air inlet on the left and right sides of the inner cover to form an air outlet passage and an air inlet passage which are arranged side by side. The front surface of the front cover is an inclined surface or a curved surface. 5 An extension wall is provided at the inner air inlet to form a circle with the partition plate. The material of the partition plate is a material having good thermal conductivity. Thereby, the heat exchange effect is improved, so that the air on the wind side can better heat the air on the air inlet side &

Further, the shape of the bottom portion of the rear cover 12 is set to be lower at the intermediate height', and is inclined toward the drain port 330. As a result, rainwater, foreign matter, and the like enter the pipe cover, and rainwater and foreign matter are discharged toward the drain through the bottom of the inclined rear cover. Since there is no mesh structure at the drain port, rainwater, foreign matter, etc. can flow out smoothly, and will not be stuck due to the net. This helps to keep the pipe cover dry and clean, which helps to better. Ventilation effect. Figure 6 is a schematic view of the inside of the front cover of the embodiment of the present invention. As shown in FIG. 6, in order to enhance the mountability between the front cover 11 and the rear cover (not shown), a card slot 1 for receiving a partition plate (not shown) is vertically disposed inside the front cover 5 〇5, the guide block 1〇6 is provided on both sides of the card slot 105. The card slot! The opening of the crucible 5 is set in an inverted "eight" shape. The so-called inverted "eight" shape means that the opening of the card slot is outwardly opened, and the partition plate (not shown) can be guided into the interior of the card slot 1〇5. The guide block 106' is located inside the front cover 11, and can guide the partition plate (not shown in the figure) from the position of the inverted "eight" shape structure to the designated position, that is, the card slot 105» when the front cover 11 is needed When the cover is placed on the back cover (not shown), the guide block 106 is aligned with the partition plate (not shown), and then the front cover 丨 is pushed forward, and the partition plate (not shown) can The structure of the inverted "eight" shape slides smoothly into the card slot 105, so that the front cover can be stuck on the back cover (not shown) 15. Thus, the front cover 11 can be easily caught on the rear cover (not shown), improving the mountability of the inlet and outlet duct cover, and improving the sealing property. Fig. 7 is a schematic view showing a first embodiment of the engagement of the front cover U and the rear cover 12 of the present invention. As shown in the figure, an elastic claw 121 is disposed above the rear cover 12, and a beveled protrusion 123 is disposed below the protrusion, and a protrusion piece 122 that is engaged with the claw 121 is provided above the front cover ,, and the lower portion is provided with The protrusion 123 is matched with the protrusion 124, and the protrusion 123 and the protrusion 124 are provided with an opening 125.

Therefore, even if the structure in which the duct 20 is inclined toward the rear cover 12 side is not provided, the duct 20 can be naturally tilted after being connected to the rear cover 12. Also, the tilting block 4〇〇 can be mounted on the lower end of the rear cover 12 as shown in Fig. iA and Fig. 10A and 10B are schematic views of the back of the back cover of the embodiment of the present invention. As shown in Figs. 1A and 10B, the inclined block 400' which is in contact with the lower portion of the duct 2 disposed at the lower portion of the duct 12 can be tilted toward the outside after the rear cover 12 and the duct 20 are mounted. Further, since the pipe naturally inclines to the outdoor side, even if rainwater, foreign matter, or the like enters the pipe 20, it will quickly flow out to the outside along the inclined pipe 2〇. It can ensure the drying inside the pipe 20 'Clean, no clogging, better ventilation effect 15 15 BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic perspective view of a prior art. ^ Fig. 2 is a schematic cross-sectional view taken along line A-A of Fig. 1.
