Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an air conditioner. Background Art

[0002] At present, the humidification function of the air conditioner can bring consumers air with appropriate humidity and eliminate the phenomenon of dry indoor air. The fresh air function can bring consumers fresh and healthy air from nature and renew the indoor air. Therefore, air conditioners with humidification and fresh air functions have become a development trend in the industry.

[0003] However, the humidification function and fresh air function of the air conditioner require separate humidification devices and fresh air devices, and the two require different fans to respectively realize the humidification and fresh air functions of the air conditioner, which undoubtedly increases the size of the air conditioner and increases the manufacturing cost of the air conditioner.

[0004] A Chinese patent (publication number: CN110701717A) discloses a fresh air device and a fresh air air conditioner indoor unit thereof, wherein the fresh air device includes: an air intake module and a fan module connected to the air intake module, and the air intake module is located below the fan module; wherein the air intake module defines an air intake chamber, the air intake chamber is connected to a fresh air intake pipe connected to the outside, and the outdoor fresh air enters the air intake chamber through the fresh air intake pipe; a humidification component is arranged in the air intake chamber for humidifying the outdoor fresh air; the humidification component includes a meandering water trough transversely arranged in the air intake chamber, water is injected into the meandering water trough for humidifying the outdoor fresh air; the outer edge of the meandering water trough is fixedly connected to the air intake chamber.

[0005] That is, the patent discloses a solution of installing a humidifier in the air inlet chamber to increase the humidity of the indoor air and improve the user's comfort. Although this solution realizes the combination of humidification function and fresh air function, it can only realize humidification and fresh air function at the same time, and cannot realize fresh air function and humidification function separately. For example, when there is no need to humidify the outdoor air in the rainy season, if humidification is performed again, the indoor air will have too high humidity; at the same time, installing a humidifier in the air inlet chamber will increase the air inlet resistance, thereby reducing the air inlet volume and extending the indoor air renewal time.

[0053] An embodiment of the present application provides an air conditioner, which is described in detail below.

[0054] First, see Figure 1 as well as Figure 2 , Figure 1 A schematic diagram of assembling an air conditioner in an embodiment of the present application is shown. Figure 2 An exploded schematic diagram of an air conditioner in an embodiment of the present application is shown, wherein the air conditioner comprises:

[0055] The fan assembly 10 includes a fan housing 11 and an air induction device 12 disposed in the fan housing 11. The fan housing 11 has a fresh air inlet 13 and a humidification air inlet 14;

[0056] The air duct assembly 20 includes an air duct housing 21 and a humidifying device 22. The air duct housing 21 has a fresh air channel 2121 and a humidifying channel 2122. The humidifying device 22 is arranged at the humidifying channel 2122. The fresh air channel 2121 is connected to the fresh air inlet 13, and the humidifying channel 2122 is connected to the humidifying inlet 14.

[0057] The switching component 30 is used to control the connection or closing between the fresh air inlet 13 and the fresh air channel 2121 , and to control the connection or closing between the humidification inlet 14 and the humidification channel 2122 .

[0058] In the present application, a fresh air inlet 13 and a humidification inlet 14 are arranged in the fan assembly 10, and a fresh air channel 2121 and a humidification channel 2122 are arranged in the air duct housing 21. The switching assembly 30 is used to control the connection or closing of the fresh air inlet 13 and the fresh air channel 2121, and the connection or closing of the humidification inlet 14 and the humidification channel 2122. Since the fresh air channel 2121 and the fresh air inlet 13, and the humidification channel 2122 and the humidification inlet 14 are independent of each other, when a single fan assembly 10 and a single air duct assembly 20 are used, the fresh air mode or the humidification mode can be turned on separately, thereby reducing the size of the air conditioner and reducing the manufacturing cost of the air conditioner.

[0059] It is worth noting that the present application can not only realize the fresh air function and the humidification function separately, for example, when the humidification air inlet 14 and the humidification channel 2122 are connected, the fresh air inlet 13 and the fresh air channel 2121 are closed to avoid the fresh air function introducing rainy season air for humidification and causing excessive indoor humidity. In addition, the fresh air function and the humidification function can be realized at the same time. For example, when the humidification air inlet 14 and the humidification channel 2122 are connected, the fresh air inlet 13 and the fresh air channel 2121 are also connected. Since the fresh air channel 2121 and the fresh air inlet 13, and the humidification channel 2122 and the humidification air inlet 14 are independent of each other, it can avoid the excessive air inlet resistance of the fresh air and the humidified air caused by the filter of the fresh air, the humidification device of the humidified air, etc., which ultimately leads to the slow renewal of the indoor air.

[0060] Specifically, the fan assembly 10 is used to provide an air induction function, to draw indoor or outdoor air, to attract outdoor air into the room to achieve a fresh air function, or to introduce indoor or outdoor air for humidification to achieve an air humidity regulation function.

[0061] The fan assembly 10 includes a fan housing 11 and an air induction device 12 disposed in the fan housing 11. The fan housing 11 has a fresh air inlet 13 and a humidification inlet 14. When the air induction device 12 is working, the air induction device 12 drives the air into the fan housing 11 from the fresh air inlet 13 or the humidification inlet 14, and then blows the air into the room through the outlet to achieve the fresh air or humidification function. Exemplarily, the air induction device 12 can be a fan with a wind wheel or a fan blade, so as to drive the air to flow into the fan housing 11 by rotating the wind wheel or the fan blade. It can be understood that the air induction device 12 or other devices that can drive air flow, such as a screw compressor.

[0062] Furthermore, in order to increase the air intake of the fan assembly 10 and improve the ventilation effect of the fresh air function and the humidification effect of the humidification function, the fan housing 11 has an air induction chamber 15 and a first chamber 16 and a second chamber 17 respectively located on both sides of the air induction chamber 15 and connected to the air induction chamber 15. The air induction device 12 is installed in the air induction chamber 15, the fresh air inlet 13 is connected to the first chamber 16 and the second chamber 17, and the humidification air inlet 14 is connected to the first chamber 16 and the second chamber 17, so that the air inlet device 12 can introduce fresh air and / or humidified air from both sides at the same time when it is working, thereby increasing the air intake of the fan assembly 10 and improving the ventilation effect of the fresh air function and the humidification effect of the humidification function.

[0063] Specifically, as an exemplary embodiment of forming the air induction chamber 15, the first chamber 16 and the second chamber 17, refer to Figure 3 , Figure 3 A structural schematic diagram of the fan assembly 10 in an embodiment of the present application is shown, wherein the fan housing 11 includes a first bracket 111, a first volute 112, a second volute 113 and a second bracket 114 which are combined in sequence, the first volute 112 and the second volute 113 form an air induction chamber 15, the first volute 112 and the first bracket 111 form a first chamber 16, and the second volute 113 and the second bracket 114 form a second chamber 17. The air induction chamber 15, the first chamber 16 and the second chamber 17 are formed by the combination of the first bracket 111, the first volute 112, the second volute 113 and the second bracket 114, thereby ensuring the assemblability of the fan assembly 10.

[0064] It is understandable that the fan housing 11 can also be combined in other ways to form the induced draft chamber 15, the first chamber 16 and the second chamber 17. For example, two housings having the first chamber 16 and the second chamber 17 are connected to form the induced draft chamber 15 in the middle.

[0065] Further, in order to facilitate the setting of the fresh air inlet 13 and the humidification inlet 14, continue to refer to Figure 3, wherein the fresh air inlet 13 is arranged at the first bracket 111 and the second bracket 114, and the humidification inlet 14 is arranged at the first volute 112 and the second volute 113; or the humidification inlet 14 is arranged at the first bracket 111 and the second bracket 114, and the fresh air inlet 13 is arranged at the first volute 112 and the second volute 113. By arranging the fresh air inlet 13 and the humidification inlet 14 at the first bracket 111, the first volute 112, the second volute 113 and the second bracket 114 respectively, the processing of the fresh air inlet 13 and the humidification inlet 14 can be facilitated, and the fresh air inlet 13 and the humidification inlet 14 can be separated at the same time, so as to control the opening or closing of the fresh air mode and the humidification mode separately.

[0066] In the present application, the preferred embodiment is to set the fresh air inlet 13 at the first bracket 111 and the second bracket 114, and the humidification air inlet 14 at the first volute 112 and the second volute 113. In this way, the fresh air inlet 13 can be set on the outside, and the humidification air inlet 14 can be set on the relatively inner side. As a result, the humidified air entering from the humidification air inlet 14 is not easy to flow to the fresh air inlet 13, thereby avoiding the phenomenon of water droplets condensing at the fresh air inlet 13 or the fresh air channel 2121.

[0067] It is understandable that the above-mentioned fan assembly 10 can also only include a volute of the air induction chamber 15 and an air induction device 12 arranged in the air induction chamber 15, and then the fresh air inlet 13 and the humidification air inlet 14 can be placed at the volute to directly drive the flow of fresh air or humidified air.

[0068] The air duct assembly 20 is used to provide a fresh air flow channel and a humidified air flow channel for the fan, so that the fan assembly 10 can introduce fresh air gas and / or humidified gas through the air duct assembly 20. The air duct assembly 20 includes an air duct housing 21 and a humidifying device 22. The air duct housing 21 has a fresh air channel 2121 and a humidifying channel 2122. The humidifying device 22 is arranged at the humidifying channel 2122. The fresh air channel 2121 is connected to the fresh air inlet 13, and the humidifying channel 2122 is connected to the humidifying inlet 14.

[0069] When the air induction device 12 is working, the fresh air in the fresh air channel 2121 or the humidified air in the humidification channel 2122 enters the air induction chamber 15 through the fresh air inlet 13 and the humidification inlet 14, and then is blown into the room through the outlet to realize the fresh air or humidification function. Exemplarily, the humidification device 22 can be a wet film or other device that can humidify air, such as a sprayer or a vibrating atomizer.

[0070] Furthermore, corresponding to the first chamber 16 and the second chamber 17 of the fan assembly 10, in order to increase the air intake of the fan assembly 10 by introducing fresh air and / or humidified air from both sides, the fresh air channel 2121 includes a first fresh air channel 210 corresponding to the first chamber 16 and a second fresh air channel 220 corresponding to the second chamber 17; the humidification channel 2122 includes a first humidification channel 230 corresponding to the first chamber 16 and a second humidification channel 240 corresponding to the second chamber 17. When the air induction device 12 is working, the fresh air is sucked into the air induction chamber 15 from the first fresh air channel 210 and the second fresh air channel 220 at the same time, and the humidified gas is sucked into the air induction chamber 15 from the first humidification channel 230 and the second humidification channel 240 at the same time, thereby increasing the air intake of the fan assembly 10, and improving the ventilation effect of the fresh air function and the humidification effect of the humidification function.

[0071] Specifically, as an exemplary embodiment of forming the first fresh air passage 210 and the second fresh air passage 220 to realize the introduction of fresh air from both sides, refer to Figure 4 , Figure 4 A structural schematic diagram of the air duct assembly 20 in an embodiment of the present application is shown, wherein the air duct housing 21 includes a water tank 211 and a water tank seat 212, the water tank 211 is provided with a humidifying air inlet 250, the humidifying device 22 includes a first wet film 221 and a second wet film 222, the first wet film 221, the second wet film 222, the water tank 211 and the water tank seat 212 enclose a humidifying air inlet channel 260, the first humidifying channel 230 and the second humidifying channel 240 are respectively arranged on the side of the first wet film 221 and the second wet film 222 away from the humidifying air inlet channel 260, so that after the air enters the humidifying air inlet channel 260 through the humidifying air inlet 250, it passes through the first wet film 221 and the second wet film 222 and enters the first humidifying channel 230 and the second humidifying channel 240 on both sides of the humidifying air inlet channel 260.

[0072] In the above embodiment, since the first wet film 221 and the second wet film 222 are arranged on the sides of the first humidification channel 230 and the second humidification channel 240, it can be ensured that the first wet film 221 and the second wet film 222 have a larger area, thereby further increasing the air intake of the humidified air. It can be understood that the first wet film 221 and the second wet film 222 can also be directly arranged inside the first humidification channel 230 and the second humidification channel 240.

[0073] Specifically, as an exemplary embodiment of forming the first humidification channel 230 and the second humidification channel 240 to achieve the introduction of humidified air from both sides, continue to refer to Figure 4The air duct shell 21 also includes a rear shell 213, which has a fresh air inlet 270. The rear shell 213 is arranged on the side of the water tank 211 away from the humidification air inlet 250. The rear shell 213 and the water tank seat 212 are enclosed to form a fresh air inlet channel 280; the first fresh air channel 210 and the second fresh air channel 220 are respectively arranged on the side of the first humidification channel 230 and the second humidification channel 240 away from the humidification air inlet channel 260. The water tank seat 212 has a partition 23 that separates the humidification air inlet channel 260 and the fresh air inlet channel 280, so that after the air enters the fresh air inlet channel 280 through the fresh air inlet 270, it is guided through the partition 23 to enter the first fresh air channel 210 and the second fresh air channel 220 on both sides of the fresh air inlet channel 280.

[0074] In the above embodiment, since the first fresh air channel 210 and the second fresh air channel 220 are respectively arranged on the side of the first humidification channel 230 and the second humidification channel 240 away from the humidification air inlet channel 260, the air duct assembly 20 forms a dual-channel humidification channel 2122 and a fresh air channel 2121 on both sides, and the humidification air inlet 250 and the fresh air inlet 270 are respectively arranged on the front and back sides. While increasing the air intake volume of fresh air and humidified air, the overall structure of the air duct assembly 20 is compact, which is beneficial to reducing the overall volume of the air conditioner.

[0075] In order to further reduce the overall volume of the air duct assembly 20 and improve the assembly reliability of the air duct assembly 20, refer to Figure 4 as well as Figure 5 , Figure 5 A structural schematic diagram of the water tank seat 212 in an embodiment of the present application is shown, wherein the air duct housing 21 also includes a first side panel 24 and a second side panel 25 respectively connected to both sides of the water tank seat 212, and the first side panel 24 and the second side panel 25 are connected to a bottom panel 26 on one side relative to the water tank seat 212, and the water tank seat 212, the first side panel 24, the second side panel 25 and the bottom panel 26 are enclosed to form an installation cavity 27, and the water tank 211 is installed in the installation cavity 27, so that the water tank seat 212 and the water tank 211 are combined to form a compact component, while improving the assembly reliability of the water tank seat 212 and the water tank 211.

[0076] It is worth noting that some of the above-mentioned embodiments mainly provide an exemplary structure of an air duct assembly 20 for increasing the air intake volume of fresh air and humidified air and ensuring the compactness of the overall structure of the air duct assembly 20. Under the guidance of this application, those skilled in the art can make equivalent design changes in the specific implementation manner, for example, a shell with four channels, two of which are provided with wet films to humidify the air, and the other two channels are connected to the outside to realize the fresh air function.

[0077] The switching component 30 is used to control the connection or closing of the fresh air inlet 13 and the fresh air channel 2121, and to control the connection or closing of the humidification inlet 14 and the humidification channel 2122. The switching component 30 includes a driving mechanism 31 and a blocking plate 32, and the driving mechanism 31 is used to drive the blocking plate 32 to control the connection or closing of the fresh air inlet 13 and the fresh air channel 2121, and to control the connection or closing of the humidification inlet 14 and the humidification channel 2122, so as to realize the start and stop of the fresh air mode and / or the humidification mode.

[0078] In some embodiments of the present application, the switching component 30 can be arranged in the air duct component 20, for example, in the fresh air channel 2121 and the humidification channel 2122, and then directly control the opening and closing of the fresh air channel 2121 and the humidification channel 2122 through the driving mechanism 31, and finally control the connection or closing of the fresh air inlet 13 and the fresh air channel 2121, and control the connection or closing of the humidification inlet 14 and the humidification channel 2122. In some other embodiments of the present application, the switching component 30 can also be arranged in the fan component 10, for example, at the fresh air inlet 13 and the humidification inlet 14, and then directly control the opening and closing of the fresh air inlet 13 and the humidification inlet 14, and finally achieve the purpose of controlling the connection or closing of the fresh air inlet 13 and the fresh air channel 2121, and controlling the connection or closing of the humidification inlet 14 and the humidification channel 2122.

[0079] In order to prevent the switching component 30 from being exposed to humid air and shortening its service life, as a preferred method, refer to Figure 1 as well as Figure 6 , Figure 6 A schematic diagram of the structure of the switching assembly 30 in the embodiment of the present application is shown, wherein the switching assembly 30 is installed between the fan assembly 10 and the air duct assembly 20, the driving mechanism 31 includes a motor 311 and a gear 312 connected to the motor 311, and a rack 321 meshing with the gear 312 is provided on the side of the blocking plate 32 away from the air duct assembly 20. Specifically, the transmission connection with the motor 311 can be through the gear 312 transmission, belt transmission or chain transmission to ensure that the gear 312 can be driven by the motor 311. It can be understood that the gear 312 can also be directly set on the rotating shaft of the motor 311. In the above embodiment, the motor 311 is started to make the gear 312 rotate forward and reverse, thereby making the blocking plate 32 with the rack 321 translate, opening and closing the fresh air channel 2121 and the humidification channel 2122, and realizing the start and close of the fresh air mode and / or the humidification mode. At the same time, since the switching component 30 is installed between the fan component 10 and the air duct component 20, the driving mechanism 31 (for example, the motor 311 part) can be as Figure 1 It is shown that it is arranged outside, so as to prevent the motor 311 from being affected by the humidified air and thus shortening its service life.

[0080] It is worth noting that the above-mentioned embodiment provides an exemplary structure of a switching component 30. Those skilled in the art can make equivalent design changes in the specific implementation method under the guidance of this application. For example, the switching component 30 drives the baffle plate 32 to rotate through the motor 311. When the baffle plate 32 rotates to a horizontal state, the humidification channel 2122 and the fresh air channel 2121 are closed. When the baffle plate 32 rotates to a vertical state, the humidification channel 2122 and the fresh air channel 2121 are opened.

[0081] Further, in order to facilitate the switching between fresh air mode and humidification mode, refer to Figure 7 as well as Figure 8 , Figure 7 A schematic diagram showing a state in which the blocking plate 32 in the embodiment of the present application is in the first working position is shown. Figure 8 A schematic diagram of a state of the air conditioner in the embodiment of the present application is shown, wherein the blocking plate 32 has a first working position. When the blocking plate 32 is in the first working position, the blocking plate 32 covers the humidification channel 2122, so that the fresh air channel 2121 is opened and the humidification channel 2122 is closed, and the air enters the fresh air inlet channel 280 through the fresh air inlet port 270, and then is sucked into the fan housing 11 by the air inlet device 12 through the fresh air channel 2121 and the fresh air inlet 13, and finally is blown into the room through the outlet of the fan housing 11 to realize the fresh air function.

[0082] Continue reading Fig. 9 as well as Fig.10 , Fig. 9 A schematic diagram showing a state in which the blocking plate 32 in the embodiment of the present application is in the second working position is shown. Fig.10 A schematic diagram shows a state of the air conditioner in a humidification mode in an embodiment of the present application, wherein the blocking plate 32 also has a second working position. When the blocking plate 32 is in the second working position, the blocking plate 32 covers the fresh air channel 2121, so that the humidification channel 2122 is opened and the fresh air channel 2121 is closed. The air enters the humidification air inlet channel 260 through the humidification air inlet 250, and then is sucked into the fan housing 11 by the air inlet device 12 through the humidification channel 2122 and the fresh air inlet 13, and finally is blown into the room through the outlet of the fan housing 11 to realize the air humidification function.

[0083] Understandably, in order to achieve both fresh air and air humidification functions, refer to Fig.11 as well as Fig.12 , Fig.11 FIG. 1 shows a state diagram of the blocking plate 32 in the third working position in the embodiment of the present application. Fig.12A schematic diagram shows a state of the air conditioner in the embodiment of the present application in the fresh air and humidification modes, wherein the blocking plate 32 can also have a third working position. When the blocking plate 32 is in the third working position, the blocking plate 32 is not in the fresh air channel 2121 or the humidification channel 2122, so that the fresh air channel 2121 and the humidification channel 2122 are opened at the same time to realize the fresh air and air humidification functions at the same time.

[0084] When the fresh air and humidification modes are turned on at the same time, since the fresh air channel 2121 and the fresh air inlet 13, and the humidification channel 2122 and the humidification inlet 14 are independent of each other, it can avoid the phenomenon of excessive resistance to the fresh air and humidified air inlet caused by the series arrangement of the fresh air filter, the humidification device of the humidified air, etc., which ultimately leads to slow indoor air renewal.

[0085] Further, in order to reduce the air inlet resistance of the air conditioner, refer to Figure 5 The fan assembly 10 is installed above the air duct assembly 20, and the fresh air channel 2121 and / or the humidification channel 2122 has a guide slope 28 for guiding the air to flow upward. The guide slope 28 can guide the air to flow upward and enter the fan assembly 10 above the air duct assembly 20, thereby reducing the air intake resistance of the air conditioner and improving the efficiency of the fresh air and air humidification functions of the air conditioner.

[0086] It is worth noting that the above description of the air conditioner is only for the purpose of clearly illustrating the verification process of the present application. Under the guidance of the present application, those skilled in the art can make equivalent modification designs to the above air conditioner. For example, the blocking plate 32 can also close the fresh air channel 2121 and the humidification channel 2122 at the same time to ensure the airtightness of the fan assembly 10 when the air conditioner is shut down.
