[0051] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0052] Please refer to the following Figure 1-14 A fresh air device 100 according to an embodiment of the present utility model is described.

[0053] Reference Figure 1 , Figure 4 , Figure 7 , Fig.13 and Fig.14 According to the embodiment of the utility model, the fresh air device 100 includes: a volute 10, a heating module 20 and a driving mechanism 30.

[0054] Specifically, the volute 10 is formed with an air duct and an exhaust port 11 connected to the air duct; the heating module 20 is movable between a first position 21 and a second position 22 relative to the volute 10. In the first position 21, the heating module 20 is located in the air duct or at the exhaust port 11 to heat the air in the air duct or flowing out from the exhaust port 11, that is, the heating module 20 can heat the air discharged from the air duct, and the heating module 20 can also heat the air flowing out from the exhaust port 11. In the second position 22, the heating module 20 is located outside the air duct and is staggered with the exhaust port 11; the driving mechanism 30 is connected to the heating module 20, and is used to drive the heating module 20 to move between the first position 21 and the second position 22.

[0055] For example, Figure 1 , Figure 4 , Figure 7 , Fig.13 and Fig.14 As shown, a wind duct extending in the up-down direction is formed in the volute 10, and the exhaust port 11 is arranged at the upper end of the wind duct. Fig.13 As shown, the heating module 20 is in the first position 21, and the heating module 20 covers the upper side of the exhaust port 11. The heating module 20 can heat the air flowing out of the exhaust port 11. Fig.14 As shown, the heating module 20 is in the second position 22, the heating module 20 does not heat the air flowing out of the exhaust port 11, and the air can flow out of the exhaust port 11 smoothly, the second position 22 and the first position 21 of the heating module 20 are in the same horizontal plane in the up and down direction, and the second position 22 is on the left side of the first position 21.

[0056] Preferably, the heating module 20 is a PTC (Positive Temperature Coefficient) heater, which is composed of a PTC ceramic heating element and an aluminum tube. This type of PTC heating element has the advantages of low thermal resistance and high heat exchange efficiency, thereby ensuring the heating effect of the heating module 20 and saving energy.

[0057] When the fresh air device 100 is in operation, when the air blown out by the fresh air device 100 does not need to be heated, the driving module drives the heating module 20 to the second position 22, and the air flows out of the volute 10 from the exhaust port 11 through the air duct. When the air blown out by the fresh air device 100 needs to be heated, the driving module drives the heating module 20 to the first position 21, and when the air flows to the exhaust port 11 through the air duct, the air flows out of the volute 10 after being heated by the heating module 20.

[0058] The fresh air device 100 of the utility model is provided with a movable heating module 20, and the position of the heating module 20 can be adjusted according to actual needs, so as to realize mode adjustment of the heating module 20 heating the air or not heating the air, thereby meeting the various usage needs of users and effectively improving the usage experience. At the same time, when the heating module 20 is not needed to heat the air in the air duct or flowing out from the exhaust port 11, the heating module 20 can be moved to the second position 22. Since the second position 22 is staggered with the exhaust port 11, the heating module 20 will not affect the air outlet of the exhaust port 11, thereby ensuring the speed of the airflow circulation at the exhaust port 11, and further ensuring the air volume of the air outlet of the air conditioner 1000.

[0059] Furthermore, in winter and other usage environments where hot air is required, heating the air through the heating module 20 at the exhaust port 11 or in the air duct can ensure that the heating module 20 can heat the air evenly, so that the air conditioner 1000 can blow out air with uniform temperature, thereby ensuring the user experience.

[0060] According to the fresh air device 100 of the embodiment of the utility model, a movable heating module 20 is provided, and the position of the heating module 20 can be adjusted according to actual needs, so as to meet the various usage needs of users and effectively improve the usage experience. At the same time, the heating module 20 can be moved to the second position 22, which can ensure the speed of air flow at the exhaust port 11, and further ensure the air volume of the air outlet of the air conditioner 1000.

Therefore, the air outlet seat 60 can guide the airflow direction of the air flowing out of the exhaust port 11, so that the air can be guided to a suitable position to achieve normal blowing of the air conditioner 1000. At the same time, the heating module 20 is arranged in the air outlet seat 60, so that it can be ensured that the heating module 20 can heat the air flowing through the heating module 20, so as to achieve the function of adjusting the blowing temperature of the air conditioner 1000.

[0062] For example, Figure 4 and Figure 8 As shown, the air outlet seat 60 is disposed on the upper side of the volute 10 , the air outlet seat 60 is connected to the volute 10 , an air outlet flow channel 61 extending in the up-down direction is defined in the air outlet seat 60 , and the lower end of the air outlet flow channel 61 is connected to the exhaust port 11 .

Thus, the mounting frame 40 can provide a mounting position for the heating module 20, so that the arrangement of the heating module 20 can be facilitated. At the same time, the mounting frame 40 can protect the heating module 20, so as to prevent the heating module 20 from colliding with other components and being damaged, thereby ensuring the service life of the heating module 20.

[0064] Furthermore, the driving mechanism 30 drives the heating module 20 to move by driving the mounting frame 40. This design is reasonable, which can ensure that the heating module 20 can move normally, and there is no need to consider the transmission form of the driving mechanism 30 and the heating module 20, thereby reducing the processing difficulty of the heating module 20.

[0065] According to some optional embodiments of the present invention, referring to Figure 4 , Figure 5 and Figure 7 The driving mechanism 30 includes: a motor 31, a gear 32 and a rack 33. The gear 32 is connected to the output shaft of the motor 31, the rack 33 is fixed to the mounting frame 40, and the gear 32 is meshed with the rack 33. Therefore, the transmission form of the rack 33 and the gear 32 is simple in structure and convenient for assembly. At the same time, the mechanical transmission form has a stable structure, so that the reliability of the driving mechanism 30 driving the mounting frame 40 to move can be improved, and then the heating module 20 can be ensured to move normally.

[0066] For example, Figure 4 , Figure 5 and Figure 7 As shown, the gear 32 is sleeved on the output shaft of the motor 31, the rack 33 extends in the left-right direction, the rack 33 is arranged on the mounting frame 40, the gear 32 is meshed with the rack 33, the motor 31 drives the gear 32 to rotate, the gear 32 drives the rack 33 to move, the rack 33 drives the mounting frame 40 to move, and the heating module 20 moves with the mounting frame 40, so that the driving mechanism 30 drives the heating module 20 to move.

[0067] According to some embodiments of the present invention, referring to Figure 5 , Figure 7 and Fig.10 A guide post 43 is formed on one of the mounting frame 40 and the air outlet seat 60, and a slide rail 63 is formed on the other. The guide post 43 is fitted in the slide rail 63, and the guide post 43 can slide along the slide rail 63. Therefore, this form of the guide post and the slide rail 63 has a simple structure and is convenient for processing. At the same time, this form of matching can also ensure the stability of the movement of the mounting frame 40 relative to the volute 10, thereby preventing the mounting frame 40 from deviating from the moving path.

[0068] For example, Figure 5 , Figure 7 and Fig.10 As shown, a guide column 43 is provided on the mounting frame 40, and the guide column 43 is provided on the rear side wall of the mounting frame 40. The guide column 43 protrudes backward. A plurality of guide columns 43 are provided, and the plurality of guide columns 43 are arranged at intervals along the left-right direction. A slide rail 63 is provided in the air outlet seat 60, and the slide rail 63 extends along the left-right direction.

[0069] According to some embodiments of the present invention, referring to Figure 5 and Figure 6 The mounting frame 40 includes: a body 41 and a plurality of support members 42, that is, the mounting frame 40 may include two, three, or four or more support members 42. The body 41 is formed into a rectangular ring; the plurality of support members 42 are arranged in the body 41 at intervals, and the two ends of the support members 42 (such as Figure 6 The left and right ends of the support members 42 shown are connected to the side walls of the body 41 , and the heating module 20 is supported on multiple support members 42 .

[0070] In this way, the arrangement space of the heating module 20 is defined in the body 41, which is convenient for the arrangement of the heating module 20. At the same time, the body 41 is a rectangular ring, which can protect the edge of the heating module 20, thereby ensuring the protection effect. In addition, the support member 42 is provided to stably support the heating module 20 in the body 41, effectively preventing the heating module 20 from separating from the body 41. At the same time, the support member 42 occupies less area than the support plate, thereby ensuring the air volume at the exhaust port 11.

[0071] For example, Figure 5 and Figure 6 As shown, the main body 41 is a rectangular ring open in the up and down directions, and includes two support members 42. The two support members 42 are arranged at intervals along the front and back directions, and the left and right ends of the support members 42 are respectively connected to the side walls inside the main body 41.

[0072] According to some optional embodiments of the present invention, referring to Figure 5 and Figure 6 The fresh air device 100 may include: a baffle 50, which is disposed on a side of the heating module 20 away from the support member 42 (eg Figure 5 The baffle 50 is fixed to the support member 42 so that the heating module 20 is sandwiched between the baffle 50 and the support member 42. Thus, the baffle 50 cooperates with the support member 42 to stably fix the heating module 20 in the body 41, thereby effectively preventing the heating module 20 from separating from the body 41.

[0073] For example, Figure 5 and Figure 6 As shown, the baffle 50 extends in the left-right direction, and the baffle 50 is snap-connected with the support member 42 disposed at the rear side, so that the heating module 20 is sandwiched between the baffle 50 and the support member 42 .

Thus, the filter 70 can filter dust in the air, thereby preventing dust in the air from being blown to the outside through the air conditioner 1000 to affect the user experience, thereby ensuring the blowing experience of the air conditioner 1000, and at the same time, the filter 70 can adsorb bacteria in the air, thereby ensuring the quality of blowing and effectively protecting the health of users.

[0075] Furthermore, when the air heated by the heating module 20 flows to the filter element 70, the heated air can disinfect the filter element 70. There is no need to remove the filter element 70 from the air conditioner 1000 for disinfection, thereby achieving disassembly-free maintenance of the filter element 70, thereby reducing the maintenance cost of the filter.

[0076] For example, Figure 4 and Fig.10 As shown, two filters 70 are provided, and the filters 70 include a formaldehyde filter and a HEPA (High efficiency particulate air Filter) filter. The formaldehyde filter is provided on the upper side of the HEPA filter, so that the filter 70 can absorb formaldehyde, bacteria and dust in the air, thereby protecting the life and health of the user.

Therefore, this fixing form is simple and easy to operate, thereby improving the assembly efficiency of the motor 31 and the air outlet seat 60. At the same time, the fastener 80 has a low structural cost and can be used in batches.

[0078] Furthermore, if Figure 8 and Fig. 9 As shown, one of the motor 31 and the air outlet seat 60 is provided with a limiting column 311 and the other is provided with a limiting hole 62, and the limiting column 311 is matched in the limiting hole 62. Therefore, the limiting column 311 cooperates with the limiting hole 62 to prevent the motor 31 from rotating relative to the air outlet seat 60, thereby ensuring the reliability of the connection between the motor 31 and the volute 10. At the same time, the cooperation between the limiting column 311 and the limiting hole 62 and the cooperation between the fastener 80 and the fixing hole can ensure the fixing strength of the motor 31 and the volute 10, and effectively prevent the motor 31 from separating from the volute 10.

[0079] For example, Figure 8 and Fig. 9 As shown, a limiting column 311 is provided on the left side of the motor 31, and the limiting column 311 extends in the radial direction of the motor 31 toward a direction away from the motor 31. A convex portion is provided on the right side of the motor 31, and a first fixing hole is provided on the convex portion and penetrates the convex portion along the thickness direction of the convex portion.
