Description

Technical Field

[0001] This utility model relates to the field of air handling equipment technology, specifically to a fan device with switchable air ducts and an air conditioning machine. Background Technology

[0002] This section provides only background information related to this application to enable those skilled in the art to understand this application more thoroughly and accurately, and it is not necessarily prior art.

[0003] As people's living standards improve, they have higher requirements for indoor air quality and humidity. Therefore, air purifiers, humidifiers, and dehumidifiers have emerged. However, purchasing all three types of machines for home use is not only costly, but more importantly, it requires separate storage, taking up a lot of space.

[0004] Therefore, integrated humidifiers combining humidification, dehumidification, and purification functions have emerged. To switch between humidification, dehumidification, and purification airflow, the fan module needs to be movable. Currently, most fan modules slide vertically up and down on the casing. To ensure smooth sliding, a large gap is usually left between the fan module and the casing. This design causes outside air to flow in through this gap when the fan module is activated, leading to airflow leakage and ultimately causing the humidification, dehumidification, and purification functions to fail. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a fan device and air conditioner with switchable air ducts. By setting a sealing ring on the fan module, and the fan module's movement trajectory on the slide rail is first sliding away from the casing, then vertically rising or falling, and finally sliding closer to the casing, this design not only ensures the smooth up-and-down sliding of the fan module, but also ensures that when the fan module slides close to the casing and the air inlet of the fan module is connected to the air outlet of the first cavity and the air outlet of the second cavity, the sealing ring on the fan module can abut against the upper and lower parts of the casing to achieve a seal. This prevents air duct leakage and avoids the failure of humidification, dehumidification, and purification functions, thereby improving the reliability of the product.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A fan device with switchable air ducts, comprising:

[0008] The housing has a first side and a second side facing each other; the first side of the housing is provided with a first cavity and a second cavity arranged vertically and independently of each other;

[0012] As an optional implementation, the slide rail includes a slide rail body, which includes a first vertical section at the top, a second vertical section at the bottom that is on the same vertical line as the first vertical section, and a third vertical section that is located between the first vertical section and the second vertical section and is arranged parallel to and spaced apart from both. One end of the third vertical section is connected to the first vertical section through a first inclined section, and the other end of the third vertical section is connected to the second vertical section through a second inclined section. When the fan module slides from the first vertical section to the second vertical section or from the second vertical section to the first vertical section, its movement trajectory is to first slide away from the casing, then slide vertically downward or upward, and finally slide towards the casing.

[0013] When the fan module is slidably mounted on the first vertical section, the fan module is close to the upper part of the housing and the air inlet of the fan module is connected to the air outlet of the first cavity, and the sealing ring abuts against the upper part of the housing to achieve air duct sealing; when the fan module is slidably mounted on the second vertical section, the fan module is close to the lower part of the housing and the air inlet of the fan module is connected to the air outlet of the second cavity, and the sealing ring abuts against the lower part of the housing to achieve air duct sealing.

[0017] When the fan module slides to a position close to the upper part of the housing and the air inlet of the fan module is connected to the air outlet of the first cavity, the first magnet and the second magnet are magnetically attracted to each other; when the fan module slides to a position close to the lower part of the housing and the air inlet of the fan module is connected to the air outlet of the second cavity, the first magnet and the second magnet are magnetically attracted to each other.

[0018] As an optional implementation, the first magnet is a plurality of first magnets arranged around the outer periphery of the air outlet end of the first cavity and a plurality of second magnets arranged around the outer periphery of the air outlet end of the second cavity, wherein the second magnet is a plurality of magnetic strips arranged around the outer periphery of the air inlet end of the fan module.

[0019] As an optional implementation, the outer sides of the two slide rail bodies in the slide rail are bent to form two limiting flanges. When the sliding seat is slidably mounted on the two slide rail bodies by a plurality of pulleys, the two sides of the sliding seat can be limited by the two limiting flanges respectively, thereby realizing the limiting of the two sides of the fan module.

[0020] As an optional implementation, a positioning structure is also included, which includes positioning holes respectively disposed on the upper and lower parts of the housing, an elastic positioning block passing through the fan module, and a button for driving the elastic positioning block to extend and retract.

[0021] When the button is pressed to retract the elastic positioning block into the fan module, the fan module can slide. When the fan module slides to a position close to the upper part of the housing and the air inlet of the fan module connects with the air outlet of the first cavity, the button can be released. The elastic positioning block then retracts and engages with the positioning hole located on the upper part of the housing for secure positioning. When the fan module slides to a position close to the lower part of the housing and the air inlet of the fan module connects with the air outlet of the second cavity, the button can be released. The elastic positioning block then retracts and engages with the positioning hole located on the lower part of the housing for secure positioning.

[0022] As an optional implementation, the positioning hole includes a first positioning hole located on one side of the upper and lower parts of the housing and a second positioning hole located on the other side of the upper and lower parts of the housing; the elastic positioning block includes a first elastic positioning block passing through one side of the fan module and a second elastic positioning block passing through the other side of the fan module, the first elastic positioning block engaging with the first positioning hole and the second elastic positioning block engaging with the second positioning hole; the button includes a first button located on one side of the fan module and engaging with the first elastic positioning block and a second button located on the other side of the fan module and engaging with the second elastic positioning block.

An air inlet is provided on the housing corresponding to the air inlet end of the fan, and the air inlet forms the air inlet end of the fan module. An air outlet is provided on the housing corresponding to the air outlet end of the fan, and the air outlet forms the air outlet end of the fan module.

[0024] The sealing ring is fitted onto the outer casing and located on the outer periphery of the air inlet; the sealing ring is a lip-shaped sealing ring.

[0025] In addition, this utility model also provides an air conditioning machine, including the above-mentioned fan device, dehumidification module, filter element and water tank module, wherein:

[0026] The dehumidification module is at least partially disposed within the first cavity;

[0027] The filter element is disposed within the second cavity;

[0028] The water tank module is located on the second side of the casing; the water tank module and the fan module are arranged vertically and their positions are interchangeable; the water tank module includes a water tank body and a humidification component that is detachably mounted on the water tank body;

[0029] When the fan module slides close to the upper part of the casing and the air inlet of the fan module is connected to the air outlet of the first cavity, under the action of the fan module, external air can enter the first cavity and be dehumidified by the dehumidification module before being discharged from the air outlet of the fan module; at this time, the water tank module is located at the lower part and is connected to the water tank body and the dehumidification module through a water guide pipe, and the condensate generated by the dehumidification module can be discharged into the water tank body through the water guide pipe;

[0030] When the fan module slides close to the lower part of the housing and the air inlet of the fan module is connected to the air outlet of the second cavity, under the action of the fan module, external air can enter the second cavity and be filtered by the filter element before being discharged from the air outlet of the fan module; at this time, the water tank module is located at the upper part and is connected to the air outlet of the fan module. Under the action of the humidification component, the air discharged from the air outlet of the fan module can be humidified by the humidification component and discharged.

[0031] In summary, the switchable air duct fan device and air conditioner provided by this utility model have the following beneficial effects:

[0032] (1) The switchable air duct fan device of this utility model is configured such that a sealing ring is set on the fan module, and the movement trajectory of the fan module on the slide rail is first to slide away from the casing, then to slide vertically up or down, and finally to slide closer to the casing. With this configuration, when the user drives the fan module to slide up and down to switch the air duct, not only can the smoothness of the fan module sliding up and down be guaranteed, but also when the fan module slides close to the casing and the air inlet of the fan module is connected to the air outlet of the first cavity and the air outlet of the second cavity respectively, the sealing ring on the fan module can abut against the upper and lower parts of the casing to achieve sealing, thereby avoiding leakage of the air duct and causing the humidification, dehumidification and purification functions to fail, thereby improving the reliability of the product.

[0033] (2) The switchable air duct fan device of this utility model sets a magnetic attraction structure between the housing and the fan module. When the fan module slides towards the housing until the air inlet of the fan module is connected to the air outlet of the first cavity and the air outlet of the second cavity respectively, the housing and the fan module are magnetically attracted by the magnetic attraction structure, so that the sealing ring and the housing fit more tightly and further improve the air duct sealing performance.

[0034] (3) The switchable air duct fan device of this utility model can bend the outer side of the two slide rail bodies in the slide rail to form a limiting fold, thereby ensuring that the fan module will not tilt or deviate to the sides when sliding on the slide rail, thus improving the sliding stability of the fan module on the slide rail; in addition, by setting a positioning structure between the housing and the fan module, the fan module can be locked and positioned when it slides to a certain position, thereby ensuring the stability and firmness of the fan module.

[0035] (4) The switchable air duct fan device of this utility model has a lip seal ring. Its lip can be deformed under the action of the extrusion force and the lip can be tightly attached to the housing. The greater the force, the tighter the fit and the better the sealing performance.

[0053] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0054] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0056] Example 1

[0057] See Figure 1-11This utility model provides a fan device with switchable air ducts, including a housing 1 and a fan module 2. The housing 1 has a first side and a second side opposite to each other. In this embodiment, the first side and the second side are the front side and the rear side of the housing 1, respectively. The front side of the housing 1 is provided with a first cavity 11 and a second cavity 12 arranged vertically and independently of each other. The fan module 2 is slidably mounted on the second side of the housing 1 via a sliding structure 3. The sliding structure 3 includes a slide rail 31 provided on the housing 1 and extending in the vertical direction, and a pulley assembly 32 slidably mounted on the slide rail 31 and connected to the fan module 2. When the fan module 2 slides along the slide rail 31 from top to bottom or from bottom to top, its movement trajectory is first sliding away from the housing 1, then vertically rising or falling, and finally sliding towards the housing 1.

[0058] In addition, a sealing ring 24 is provided on the outer periphery of the air inlet end of the fan module 2; when the fan module 2 slides close to the upper part of the housing 1 and the air inlet end of the fan module 2 is connected to the air outlet end of the first cavity 11, the sealing ring 24 abuts against the upper part of the housing 1 to achieve air duct sealing; when the fan module 2 slides close to the lower part of the housing 1 and the air inlet end of the fan module 2 is connected to the air outlet end of the second cavity 12, the sealing ring 24 abuts against the lower part of the housing 1 to achieve air duct sealing.

[0059] Therefore, by setting a sealing ring 24 on the fan module 2, and ensuring that the fan module 2 moves along the slide rail 31 by first sliding away from the housing 1, then vertically rising or falling, and finally sliding closer to the housing 1, when the user moves the fan module 2 up and down to switch air ducts, not only can the smoothness of the fan module 2's up and down movement be guaranteed, but also when the fan module 2 slides close to the housing 1 and the air inlet of the fan module 2 is connected to the air outlet of the first cavity 11 and the air outlet of the second cavity 12 respectively, the sealing ring 24 on the fan module 2 can abut against the upper and lower parts of the housing 1 respectively to achieve sealing, thereby preventing air duct leakage and causing the humidification, dehumidification, and purification functions to fail, thus improving the reliability of the product.

[0060] The first cavity 11 has several first air outlet holes 111 on its rear side wall to form the air outlet end of the first cavity 11, and the second cavity 12 has several second air outlet holes 121 on its rear side wall to form the air outlet end of the second cavity 12. The fan module 2 includes a housing 21 and a fan 23 disposed inside the housing 21. The front side wall of the housing 21 has an air inlet 211 corresponding to the air inlet end of the fan 23, and the air inlet 211 forms the air inlet end of the fan module 2. The top wall of the housing 21 has an air outlet 212 corresponding to the air outlet end of the fan 23, and the air outlet 212 forms the air outlet end of the fan module 2. In addition, it also includes a cover plate 22 covering the top of the housing 21, and an air outlet grille 221 is provided on the cover plate 22.

[0061] See Figure 4-5 The slide rail 31 includes a slide rail body, which includes a first vertical section 311 located at the top, a second vertical section 312 located at the bottom and on the same vertical line as the first vertical section 311, and a third vertical section 313 located between the first vertical section 311 and the second vertical section 312 and arranged parallel to and spaced apart from them. One end of the third vertical section 313 is connected to the first vertical section 311 through a first inclined section 314, and the other end of the third vertical section 313 is connected to the second vertical section 312 through a second inclined section 315. When the fan module 2 slides from the first vertical section 311 to the second vertical section 312 or from the second vertical section 312 to the first vertical section 311, its movement trajectory is to first slide away from the housing 1, then slide vertically downward or upward, and finally slide towards the housing 1.

[0062] When the fan module 2 is slidably mounted on the first vertical section 311, the fan module 2 is close to the upper part of the housing 1 and the air inlet of the fan module 2 is connected to the air outlet of the first cavity 11. At this time, the sealing ring 24 abuts against the upper part of the housing 1 to achieve air duct sealing. When the fan module 2 is started, external air can enter the first cavity 11 and then pass through the air outlet of the first cavity 11, the air inlet of the fan module 2 and the air outlet of the fan module 2 in sequence before being discharged. When the fan module 2 is slidably mounted on the second vertical section 312, the fan module 2 is close to the lower part of the housing 1 and the air inlet of the fan module 2 is connected to the air outlet of the second cavity 12. At this time, the sealing ring 24 abuts against the lower part of the housing 1 to achieve air duct sealing. When the fan module 2 is started, external air can enter the second cavity 12 and then pass through the air outlet of the second cavity 12, the air inlet of the fan module 2 and the air outlet of the fan module 2 in sequence before being discharged.

[0063] See Figure 4-5 The slide rail 31 includes two slide rail bodies, which are arranged at intervals and connected by a horizontal connecting section 316 between the two first vertical sections 311 of the two slide rail bodies; the pulley assembly 32 includes a sliding seat 321 and a plurality of pulleys 322 disposed on both sides of the sliding seat 321, which are respectively slidably mounted on the two slide rail bodies; wherein, the front side wall of the outer shell 21 of the fan module 2 is provided with a mounting seat 213, which is connected to the sliding seat 321.

[0064] In this embodiment, the sliding seat 321 is provided with a plurality of first mounting holes 3211 spaced apart in the vertical direction, and the mounting seat 213 is provided with a plurality of second mounting holes 2131 correspondingly. Preferably, the first mounting holes 3211 are through holes and the second mounting holes 2131 are threaded holes. The connection and fixation between the mounting seat 213 and the sliding seat 321 can be achieved by passing a bolt through the first mounting holes 3211 and threading it into the second mounting holes 2131.

[0065] In this embodiment, the sliding structure 3 is provided in four sets; wherein, the four slide rails 31 are arranged in pairs on the upper and lower parts of the housing 1, and the two slide rails 31 on the upper part and the two slide rails 31 on the lower part are arranged at intervals; the four pulley assemblies 32 are respectively slidably mounted on the four slide rails 31.

[0066] See Figure 6-8 The system also includes a magnetic attraction structure, which comprises a first magnet disposed on the upper and lower parts of the housing 1 and a second magnet disposed on the front side wall of the outer shell 21 of the fan module 2. The magnetic poles of the first magnet and the second magnet are opposite. Preferably, the first magnet consists of a plurality of first magnets 13 arranged around the outer periphery of the air outlet of the first cavity 11 and a plurality of second magnets 14 arranged around the outer periphery of the air outlet of the second cavity 12. The second magnet consists of a plurality of magnetic strips 25 arranged around the outer periphery of the air inlet 211 of the outer shell 21. Thus, when the fan module 2 is slid to a position close to the upper part of the housing 1 and the air inlet of the fan module 2 is connected to the air outlet of the first cavity 11, the plurality of first magnets 13 and the plurality of magnetic strips 25 are magnetically attracted. When the fan module 2 is slid to a position close to the lower part of the housing 1 and the air inlet of the fan module 2 is connected to the air outlet of the second cavity 12, the plurality of second magnets 14 and the plurality of magnetic strips 25 are magnetically attracted. Therefore, by setting up a magnetic attraction structure, the sealing ring 24 can fit more tightly with the housing 1, further improving the air duct sealing performance.

[0067] Furthermore, the outer edges of both slide rail bodies in the slide rail 31 are bent to form two limiting flanges 317. When the sliding seat 321 is slidably mounted on the two slide rail bodies via several pulleys 322, both sides of the sliding seat 321 can be limited by the two limiting flanges 317, thereby achieving the limitation of both sides of the fan module 2. This arrangement ensures that the fan module 2 will not tilt or shift to either side when sliding on the slide rail 31, thus improving the sliding stability of the fan module 2 on the slide rail 31.

[0068] See Figure 6 as well as Figure 8-9It also includes a positioning structure disposed between the housing 1 and the fan module 2. The positioning structure includes positioning holes disposed on the upper and lower parts of the housing 1, an elastic positioning block passing through the fan module 2, and a button for driving the elastic positioning block to extend and retract. Specifically, the positioning holes include a first positioning locking hole 15 located on one side of the upper and lower parts of the housing 1 and a second positioning locking hole 16 located on the other side of the upper and lower parts of the housing 1. The elastic positioning block includes a first elastic positioning locking block 215 passing through one side of the fan module 2 and a second elastic positioning locking block 217 passing through the other side of the fan module 2. The first elastic positioning locking block 215 is used to engage with the first positioning locking hole 15, and the second elastic positioning locking block 217 is used to engage with the second positioning locking hole 16. The button includes a first button 214 disposed on one side of the fan module 2 and drivingly engaging with the first elastic positioning locking block 215, and a second button 216 disposed on the other side of the fan module 2 and drivingly engaging with the second elastic positioning locking block 217.

[0069] Therefore, when the user presses the first button 214 and the second button 216 simultaneously, the first elastic positioning block 215 and the second elastic positioning block 217 can be retracted into the outer casing 21, respectively. At this time, the fan module 2 can be moved up and down. When the fan module 2 is moved to a position close to the upper part of the casing 1 and the air inlet 211 of the casing 21 is connected to the air outlet of the first cavity 11, the first button 214 and the second button 216 can be released. The first elastic positioning block 215 will then retract and lock into the first positioning hole 15, and the second elastic positioning block 216 will retract into the first positioning hole 15. 17 retracts and engages within the second positioning hole 16, thereby securing the fan module 2 to the upper part of the housing 1. Conversely, when the fan module 2 slides close to the lower part of the housing 1 and the air inlet 211 of the outer casing 21 connects to the air outlet of the second cavity 12, the first button 214 and the second button 216 can be released. The first elastic positioning block 215 retracts and engages within the first positioning hole 15, and the second elastic positioning block 217 retracts and engages within the second positioning hole 16, thereby securing the fan module 2 to the lower part of the housing 1. Thus, by setting a positioning structure between the housing 1 and the fan module 2, the fan module 2 can be secured and positioned when it slides to a certain position, ensuring the stability and firmness of the fan module 2.

[0070] See also Figure 10 The sealing ring 24 is fitted around the air inlet 211 of the outer casing 21, and several magnetic strips 25 are arranged and fixed around the casing 1 to press and fix the sealing ring 24. The sealing ring 24 is a lip sealing ring with a Y-shaped lip 241 protruding from its front end. Thus, by using a lip sealing ring, its lip can be deformed under the pressure of compression, and the lip 241 can be tightly fitted to the casing 1. The greater the force, the tighter the fit and the better the sealing performance.

[0071] Example 2

[0072] See Figure 12-15 This utility model also provides an air conditioning unit, including the fan device, dehumidification module, filter element 6, and water tank module 4 of the above embodiment 1. The dehumidification module includes at least a portion disposed within the first cavity 11; the filter element 6 is disposed within the second cavity 12; the water tank module 4 is disposed on the second side of the housing 1, and the water tank module 4 and the fan module 2 are arranged vertically and interchangeably; the water tank module 4 includes a water tank body and a humidification component (not shown in the figure) detachably disposed on the water tank body.

[0073] When the fan module 2 is slid close to the upper part of the housing 1 and the air inlet of the fan module 2 is connected to the air outlet of the first cavity 11 (e.g.) Figure 12 As shown, under the action of the fan module 2, external air can enter the first cavity 11 and be dehumidified by the dehumidification module before being discharged from the air outlet of the fan module 2; at this time, the water tank module 4 is located at the bottom and is connected to the water tank body and the dehumidification module through the water guide pipe 531. The condensate generated by the dehumidification module can be discharged into the water tank body through the water guide pipe 531 to realize the recovery of condensate.

[0074] When the fan module 2 is slid close to the lower part of the housing 1 and the air inlet of the fan module 2 is connected to the air outlet of the second cavity 12, under the action of the fan module 2, the outside air can enter the second cavity 12 and be filtered by the filter element 6 before being discharged from the air outlet of the fan module 2; at this time, the water tank module 4 is located at the upper part and is connected to the air outlet of the fan module 2. Under the action of the humidification component, the air discharged from the air outlet of the fan module 2 can be humidified by the humidification component and discharged.

[0075] Additionally, it includes a first front panel 7 and a second front panel 8. Both the first cavity 11 and the second cavity 12 have front openings.
