Description

Technical Field

[0001] This invention relates to the technical field of home appliances, and more specifically, to a heat exchange device. Background Technology

[0002] Heat exchange equipment is widely used in our daily work and life. Air conditioning is one type of heat exchange equipment. Taking air conditioning as an example, air conditioning involves air intake and air exhaust when regulating the temperature of cold and hot air.

[0003] Currently, most air conditioner indoor unit filters rely on manual, periodic removal and cleaning. However, many users frequently forget to clean them, and since air conditioners are often mounted high, frequent filter removal and installation is inconvenient. This leads to a buildup of dust and dirt on the filter during use, which not only reduces airflow and affects air conditioner performance but also causes secondary pollution of indoor air quality. While some air conditioners offer automatic filter cleaning, users still need to periodically empty the dust collection box, albeit at longer intervals than with filter cleaning, which is still a relatively inconvenient task.

[0004] As can be seen from the above, the filtration structure of existing heat exchange equipment has problems such as complicated cleaning and inconvenient operation. Summary of the Invention

[0052] Example 1

[0053] To address the problems of complex cleaning and inconvenient operation associated with the filtration structures of existing heat exchange devices, this invention provides a heat exchange device. This heat exchange device can be used in both industrial and domestic applications.

[0054] Among them, the heat exchange equipment can be an air conditioner, specifically a wall-mounted air conditioner.

[0055] like Figures 1 to 12 As shown, the heat exchange device includes a housing 10 and a filter cleaning assembly. A dust collection recess 110 is formed on the inner wall of the housing 10. The filter cleaning assembly is disposed inside the housing 10. At least a portion of the dust collection recess 110 is located below the filter cleaning assembly. The dust collection recess 110 is used to collect dust that falls from the filter cleaning assembly.

[0056] Specifically, dust falling from the filter cleaning component is transferred to the interior of the dust collection recess 110, where it is then removed to the exterior of the heat exchanger by condensate. This application utilizes a dust collection recess 110 formed on the inner wall of the housing 10 to collect dust falling from the filter cleaning component, eliminating the need for a separate dust collection box. This avoids the need for users to periodically disassemble the dust collection box to empty it, simplifying the structure of the filter cleaning component and improving the user experience of the heat exchanger.

[0057] It should be noted that part of the condensate formed by the condenser of the heat exchanger flows into the dust collection recess 110, and the other part enters the water receiving tray below the air outlet of the housing 10. The condensate flowing into the dust collection recess 110 will clean the dust collected in the dust collection recess 110 and move it to the outside of the heat exchanger along with the condensate.

[0058] Furthermore, the dust collection recess is located in the bottom area of ​​the housing so that dust will enter the interior of the dust collection recess 110 under the action of gravity.

[0059] Furthermore, to ensure that all dust falling from the filter cleaning component is collected by the dust collection recess 110, the extending direction of the dust collection recess 110 is the same as the extending direction of the cleaning component 30 of the filter cleaning component. Also, the extending length of the dust collection recess 110 is greater than the extending length of the cleaning component 30.

[0060] In this embodiment, the dust collection recess 110 is a long, narrow groove with its opening facing upwards to facilitate dust collection.

[0061] like Figure 4 , Figure 8 and Figure 9 As shown, the inner wall of the housing 10 also has a guide surface 120, which is located below the filter cleaning assembly. The guide surface 120 extends downward at an angle close to the dust collection recess 110. The guide surface 120 and the filter cleaning assembly are spaced apart to form a channel, so that the dust of the filter cleaning assembly enters the interior of the dust collection recess 110 through the channel along the guide surface 120.

[0062] The guide surface 120 is inclined so that when dust falls onto the guide surface 120, under the action of gravity, the dust enters the interior of the dust collection recess 110 along the guide surface 120. The condensate inside the dust collection recess 110 flushes the dust into the drain channel 130 and then discharges it from the housing 10.

[0063] Furthermore, a drain channel 130 is formed on the inner wall of the housing 10, located downstream of the dust collection recess 110. The end of the drain channel 130 away from the dust collection recess 110 is connected to the outside of the housing 10. The dust collection recess 110 is used to collect dust, and condensate flows into the dust collection recess 110 and then flows out through the drain channel 130 to the outside of the housing 10.

[0064] Furthermore, the drain channel 130 is located on the side of the housing 10 and communicates with the outside of the housing 10 to achieve the technical effect of draining liquid.

[0065] In this embodiment, the distance between the guide surface 120 and the filter assembly 20 is 5-10mm, and the specific distance can be 5mm, 6mm, 7mm, 8mm, 9mm, or 10mm.

[0066] It should be noted that if the gap is too small, dust will not be able to enter the dust collection recess 110 smoothly, affecting the dust removal efficiency; at the same time, the gap should not be too large, causing some air intake to bypass the filter 210, affecting the air purification effect.

[0067] like Figure 10 As shown, the heat exchange device also includes a stop member 60 and a stop drive member. The stop member 60 has a water storage position and a water discharge position. When the stop member 60 is in the water storage position, the stop member 60 stops between the dust collection recess 110 and the drain channel 130 to stop the condensate. When the stop member 60 is in the water discharge position, the dust collection recess 110 and the drain channel 130 are connected. The stop drive member is installed on the housing 10 and is drivenly connected to the stop member 60. The stop drive member provides driving force for the stop member 60 to switch between the water storage position and the water discharge position.

[0068] Specifically, condensate enters the first end of the dust collection recess 110, and the second end of the dust collection recess 110 is connected to the drain channel 130. The stop member 60 slides inside the dust collection recess 110. When the stop member 60 is in the water storage position, the condensate is stored between the stop member 60 and the first end of the dust collection recess 110. When there is enough condensate, the stop member 60 switches from the water storage position to the water discharge position. The stop member 60 moves toward the drain channel 130 and moves to the position between the connection port of the dust collection recess 110 and the drain channel 130 and the second end of the dust collection recess 110, so that the condensate can flow into the interior of the drain channel 130.

[0069] Of course, the stop 60 can be partially located at the connection between the dust collection recess 110 and the drain channel 130, as long as it does not affect normal draining.

[0070] Furthermore, the outer peripheral surface of the stop 60 is fitted and slidably connected to the inner wall surface of the dust collection recess 110, so that the inner wall of the dust collection recess 110 can be cleaned during the sliding process of the stop 60 inside the dust collection recess 110, thus assisting in dust treatment.

[0071] In this embodiment, the heat exchange device further includes a sensor and a controller. The sensor is disposed on the housing 10 and is used to detect the position information of the stop 60. The controller is signal-connected to the sensor, receives the position information, and can transmit the position information of the stop 60 outward. The sensor may be a displacement sensor.

[0072] Furthermore, the heat exchanger also includes a screw, a stop member 60 with a threaded hole through which the screw passes, the stop member 60 being threadedly engaged with the screw, and a stop drive member being drivenly connected to the screw. The stop member 60 is driven to move along the dust collection recess 110 by engaging with the screw.

[0073] It should be noted that the stop drive is a rotary motor, which drives the screw to rotate.

[0074] like Figures 1 to 12 As shown, the filter cleaning assembly includes a filter screen assembly 20 and a cleaning assembly 30 disposed inside the housing 10. The filter screen assembly 20 includes a filter screen 210, which is rotatably disposed at the air inlet of the housing 10. The cleaning assembly 30 is adjustablely disposed on at least one side of the filter screen 210. The cleaning assembly 30 has a clean position that contacts the filter screen 210 and a non-clean position that is detached from the filter screen 210.

[0075] Furthermore, the heat exchange device includes a housing 10, which has an air inlet. The filter assembly 20 and the cleaning assembly 30 of the filter and cleaning components are both disposed inside the housing 10. At least a portion of the filter assembly 20 is disposed corresponding to the air inlet, and at least a portion of the cleaning assembly 30 is connected to the housing 10 and / or the filter assembly 20.

[0076] The cleaning component 30 can be installed on the filter assembly 20 to fix the cleaning component 30, or the cleaning component 30 can be installed on the housing 10 to fix the cleaning component 30.

[0077] Furthermore, the air inlet extends along the length of the housing 10, and the filter 210 is correspondingly arranged with the air inlet, so that the filter support 220 and the rotating shaft 320 also extend along the length of the housing 10.

[0078] In this embodiment, the cleaning component 30 is disposed between the air inlet and the filter assembly 20. After cleaning the filter 210, the cleaning component 30 switches its position to face the side of the air inlet, but not to the bottom of the air inlet, thus ensuring that the air entering through the air inlet does not blow away the dust on the cleaning component 30.

[0079] Of course, it is also possible to place the cleaning component 30 on the side of the filter assembly 20 away from the air inlet. When the cleaning component 30 is placed on the side of the filter assembly 20 away from the air inlet, the cleaning component 30 is in a position that avoids airflow.

[0080] like Figures 1 to 12 As shown, a dust block 50 is provided on the housing 10, which abuts against the dust block 50 when the cleaning component 30 moves to a non-cleaning position.

[0081] Specifically, when the cleaning component 30 moves to a non-cleaning position, the cleaning component 30 collides with the dust block 50, so as to remove the dust from the cleaning component 30 by shaking it off.

[0082] Furthermore, the housing 10 has a dust collection recess 110, which is used to collect dust that falls from the cleaning component 30. The dust collection recess 110 is filled with condensate discharged from the air conditioner. When the condensate flows inside the dust collection recess 110, it carries the dust out of the dust collection recess 110.

[0083] In this embodiment, the cleaning component 30 transfers the dust on the filter 210 to the interior of the dust collection recess 110 by adjusting its position, and discharges the condensate inside the dust collection recess 110 into the housing 10.

[0084] When the cleaning component 30 is in the cleaning position, at least a portion of the cleaning component 30 is in contact with the filter screen 210 to transfer dust from the filter screen 210 to the cleaning component 30. After the cleaning component 30 switches from the cleaning position to the non-cleaning position, the cleaning component 30 transfers the dust, at which point the cleaning component 30 detaches from the filter screen 210.

[0085] Specifically, this application uses a rotating filter 210 to filter the air, and the cleaning component 30 transfers the dust on the filter 210 by adjusting its position, eliminating the need for manual disassembly and cleaning, thus improving cleaning efficiency; at the same time, there is no need to set up a separate dust collection device, avoiding the need for users to regularly disassemble the dust collection box to empty dust and debris, thus simplifying the structure of the filter cleaning component.

[0086] Furthermore, the cleaning component 30 can be disposed on one side of the filter 210 or on both sides of the filter 210. The specific placement of the filter 210 and the cleaning component 30 can be adaptively adjusted. For example, when the cleaning component 30 is in the cleaning position, the cleaning component 30 can contact the middle area of ​​the filter 210, the lower area of ​​the filter 210, or the upper area of ​​the filter 210.

[0087] In this embodiment, to prevent the air flowing through the filter 210 from carrying dust and debris from the cleaning component 30 into the air, the cleaning component 30 is positioned to avoid airflow, and the specific position is adjusted according to the specific position of the receiving device.

[0088] like Figures 4 to 7 As shown, the cleaning component 30 includes a cleaning drive 310 and a cleaning component 330. The cleaning drive 310 is driven to connect with the cleaning component 330 so that the cleaning component 330 can switch between a cleaning position and a non-cleaning position.

[0089] The cleaning drive unit 310 drives the cleaning unit 330 to swing, thereby switching the cleaning unit 330 between a cleaning position and a non-cleaning position. In the cleaning position, the cleaning unit 330 contacts the filter screen 210 to remove dust, and the dust on the filter screen 210 moves to the cleaning unit 330. The cleaning unit 330 can switch from the cleaning position to the non-cleaning position by swinging.

[0090] Specifically, the cleaning assembly 30 also includes a rotating shaft 320, a cleaning drive 310 is drivenly connected to the rotating shaft 320, a cleaning component 330 is disposed on the rotating shaft 320 and swings with the movement of the rotating shaft 320, the cleaning drive 310 drives the rotating shaft 320 to rotate, so that the rotating shaft 320 drives the cleaning component 330 to swing along with it, the rotating shaft 320 has a preset extension length so that the length of the cleaning component 330 is not less than the filter screen 210, so that the filter screen 210 can be completely cleaned when the cleaning component 330 contacts the filter screen 210.

[0091] It should be noted that the cleaning component 330 is a brush, and the length of the brush in the circumferential direction of the rotating shaft 320 is less than half the circumferential length of the rotating shaft 320. This ensures that the cleaning component 330 can transfer dust. Under the driving effect of the cleaning drive component 310, the cleaning component 330 switches between a cleaning position and a non-cleaning position.

[0092] In this embodiment, to avoid the rotating shaft 320 being too long, the rotating shaft 320 includes multiple mounting sections 321 and a transmission structure 322 disposed between two adjacent mounting sections 321. The cleaning component 330 includes multiple cleaning sections, and each mounting section 321 is provided with at least one cleaning section. When multiple cleaning component 330 sections are provided on each mounting section 321, the multiple cleaning components 330 are spaced apart along the swing direction of the rotating shaft 320, i.e., the circumferential direction of the rotating shaft 320, thereby realizing the cleaning effect of multiple cleaning components 330 on the filter screen 210 by swinging, thus improving the cleaning efficiency.

[0093] like Figures 1 to 7 As shown, the filter assembly 20 also includes a filter support 220. The filter 210 is movably mounted on the filter support 220. The mounting section 321 rotates synchronously with the transmission structure 322. The transmission structure 322 includes a connecting rod 3221 and a transmission sleeve 3222. There are two connecting rods 3221 extending relative to each other between two adjacent mounting sections 321. The two connecting rods 3221 extending relative to each other are respectively inserted into the interior of both ends of the transmission sleeve 3222, and the transmission sleeve 3222 is rotatably mounted on the filter support 220.

[0094] Specifically, the transmission sleeve 3222 is rotatably mounted on the filter support 220 so that when the cleaning drive 310 drives the transmission structure 322 to rotate, the connecting rod 3221 and the transmission sleeve 3222 rotate synchronously, so that the two adjacent cleaning sections rotate synchronously. The transmission sleeve 3222 is mounted on the filter support 220 so that the filter support 220 supports the transmission structure 322 through the transmission sleeve 3222, so as to avoid the phenomenon that the rotating shaft 320 is too long and deformed, which would affect the cleaning efficiency.

[0095] Furthermore, the two ends of the connecting rod 3221 are respectively inserted into the transmission sleeve 3222 and the mounting section 321. The connecting rod 3221 rotates synchronously with the transmission sleeve 3222 and the mounting section 321. The connection between the connecting rod 3221 and the transmission sleeve 3222 can be achieved by having a flat protrusion on the connecting rod 3221 and a flat slot on the transmission sleeve 3222, using the cooperation of the flat slot and the flat protrusion to achieve synchronous rotation. Conversely, it is also possible to have a flat slot on the connecting rod 3221 and a flat protrusion on the transmission sleeve 3222.

[0096] Similarly, the connection between the connecting rod 3221 and the mounting section 321 can be achieved by having a flat protrusion on the connecting rod 3221 and a flat slot on the mounting section 321, using the cooperation of the flat slot and the flat protrusion to achieve synchronous rotation of the two. Conversely, it is also possible to have a flat slot on the connecting rod 3221 and a flat protrusion on the mounting section 321.

[0097] In this embodiment, the filter support 220 is provided with an installation channel 2231, and the outer periphery of both ends of the transmission sleeve 3222 is provided with protrusions 32221, which are located on the outer sides of both ends of the installation channel 2231. To prevent the cleaning component 330 from shifting, the transmission sleeve 3222 is adapted to the installation channel 2231. When the rotating shaft 320 tends to shift along its length, the protrusions 32221 and the outer surfaces of both ends of the installation channel 2231 stop and limit the transmission sleeve 3222, thereby ensuring that the rotating shaft 320 does not move and improving the stability of cleaning.

[0098] In this embodiment, the filter assembly 20 further includes a filter support 220, and the filter 210 is movably disposed on the filter support 220 in a closed-loop structure so that the filter 210 rotates cyclically on the filter support 220; and a filter drive unit, which is mounted on the filter support 220 to drive the filter 210 to rotate.

[0099] like Figures 1 to 9 As shown, the filter assembly 20 also includes a filter support 220. The filter 210 is movably disposed on the filter support 220 in a closed-loop structure so that the filter 210 rotates cyclically on the filter support 220. The filter drive unit is installed on the filter support 220 to drive the filter 210 to rotate.

[0100] Specifically, the filter screen 210 rotates cyclically on the filter screen support 220 to ensure that the filter screen 210 always maintains a filtering state.

[0101] Furthermore, the filter drive unit is mounted on the filter support 220, and the filter drive unit provides driving force for the movement of the filter 210.

[0102] The filter drive component 231 can be a rotary motor or a rotary cylinder, depending on whether it can provide rotary driving force.

[0103] Furthermore, the filter screen 210 has a preset length, and the length of the rotating shaft 320 is not less than the length of the filter screen 210.

[0104] In this embodiment, the cleaning component 30 is located outside the filter screen 210 of the closed-loop structure, so as to clean the outside of the filter screen 210 by the cleaning member 330. After the cleaning member 330 swings with the rotating shaft 320, the cleaning member 330 transfers the dust on the filter screen 210 to a position away from the filter screen 210.

[0105] like Figures 1 to 7 As shown, a circumferentially arranged rack is provided on the inner surface of the filter screen 210. The filter screen drive unit includes a filter screen drive component 231, a roller 232 and a gear. The roller 232 is movably connected to the filter screen support 220. The filter screen drive component 231 is drivenly connected to the roller 232. The gear is provided on the roller 232 and meshes with the rack so that the roller 232 rotates and drives the filter screen 210 to move.

[0106] Specifically, the roller 232 mounted on the filter support 220 is rotatably arranged. The roller 232 is used to support the filter 210, and the filter 210 is driven to rotate by setting gears on the roller 232. The rack on the flexible filter 210 meshes with the gears to transmit power.

[0107] Furthermore, there may be multiple gears and racks, which are spaced apart along the axial direction of the rotating shaft 320. The specific positions and number of gears and racks are determined to enable the roller 232 to drive the filter screen 210 to rotate.

[0108] In this embodiment, two rollers 232 are provided along the height protection line. The two rollers 232 are located at both ends of the filter screen support 220 to facilitate the drive cooperation with the filter screen 210 to realize the rotation of the filter screen 210.

[0109] like Figures 1 to 3 As shown, the filter support 220 includes two baffles 221 arranged opposite to each other and a crossbeam 222 for connecting the two baffles 221, and a receiving area for receiving the filter 210 is formed between the two baffles 221.

[0110] Specifically, the roller 232 is rotatably housed inside the receiving area. The roller 232 may be rotatably connected to the baffle 221. One of the roller 232 and the baffle 221 is provided with a through hole, and the other of the two is provided with a protrusion. At least a portion of the protrusion extends into the through hole, and the protrusion is rotatably disposed inside the through hole to realize the movable connection between the roller 232 and the baffle 221.

[0111] Furthermore, the filter support 220 also includes a connecting frame 223, which is connected to the crossbeam 222. The connecting frame 223 extends in the same direction as the baffle 221 and is located between the two baffles 221. The accommodating area is divided into a first region 2211 and a second region 2212 by the connecting frame 223. The filter drive unit is provided in one or two sets. When the filter drive unit is provided in two sets, there is a set of filter drive units corresponding to the first region 2211 and the second region 2212 respectively.

[0112] The connecting frame 223 cooperates with the crossbeam 222 to divide the area by connecting frame 223, so that filter drive units are installed in the first area 2211 and the second area 2212 respectively. The two ends of the roller 232 inside the first area 2211 and the second area 2212 are rotatably connected to the baffle 221 and the connecting frame 223 respectively.

[0113] Furthermore, the connecting frame 223 is provided with an installation channel 2231 for placing the transmission sleeve 3222 of the filter cleaning component 330.

[0114] In this embodiment, in order to enhance the strength of the filter support 220, the filter support 220 further includes one or more reinforcing ribs 224. The reinforcing ribs 224 can be connected in several ways: the reinforcing ribs 224 are located between two crossbeams 222, between the baffle 221 and the connecting frame 223, between two baffles 221, between the baffle 221 and the crossbeam 222, or between the crossbeam 222 and the connecting frame 223. The reinforcing ribs 224 are designed to achieve the technical effect of strengthening the connection. Specifically, the reinforcing ribs 224 can be a combination of the above methods.

[0115] like Figure 1 and Figure 9 As shown, the heat exchange equipment also includes a cover 40, which is disposed between the air inlet and the filter assembly 20. The cover 40 has a communication port, and one side of the cover 40 extends to the side wall of the housing 10 on the side where the guide surface 120 is located, so that air is blown into the filter assembly 20 through the air inlet and communication port of the housing.

[0116] Specifically, the cover 40 serves to protect the cleaning component 30 and the filter component 20. At the same time, the cover 40 blocks the channel so that the air entering the interior of the housing 10 through the air inlet is blown into the filter component 20 through the air inlet and the connecting port, thus preventing air from entering the interior of the channel and affecting the air purification effect.

[0117] In this embodiment, the housing 10 has flanges 140 at opposite ends. One of the flanges 140 and the filter assembly 20 has a mounting hole, and the other has a mounting protrusion. At least a portion of the mounting protrusion extends into the mounting hole to mount the filter assembly 20 onto the housing 10. Similarly, the cleaning assembly 30 can also be mounted in the same way, with one of the flanges 140 and the cleaning assembly 30 having a mounting hole, and the other having a mounting protrusion, at least a portion of which extends into the mounting hole.

[0118] Example 2

[0119] Unlike Embodiment 1, in this embodiment, the cleaning component 330 switches between a cleaning position and a non-cleaning position in a sliding manner under the driving action of the cleaning drive component 310.

[0120] Specifically, the cleaning drive 310 drives the cleaning component 330 to move toward or away from the filter screen 210, thereby achieving the effect of cleaning the filter screen 210 by contacting the cleaning component 330 with the filter screen 210 and cleaning the filter screen 210, as well as detaching the cleaning component 330 from the filter screen 210 after cleaning the filter screen 210.

[0121] Furthermore, the cleaning drive 310 is a push cylinder or a telescopic motor.

[0122] Example 3

[0123] The difference between this embodiment and embodiment one is that in this embodiment, magnetic force is used to make the stop 60 slide inside the dust collection recess 110.

[0124] Specifically, the stop 60 is made of magnetic material, and the stop drive is a magnetic guide rail with adjustable magnetic direction set in the dust collection recess 110. The position of the stop 60 is adjusted by changing the magnitude and direction of the magnetic force of the magnetic channel.

[0125] In this embodiment, increasing the magnetic attraction of the stop 60 ensures that it is completely flush against the dust collection recess 110, allowing for the cleaning of dust and debris inside the recess with each movement. Reducing the magnetic force causes the stop 60 to float slightly, reducing frictional noise during movement. The left and right movement of the stop 60 is achieved by changing the magnetic direction of the magnetic guide rail.

[0126] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0127] 1. This application uses a rotating filter screen 210 to filter the air, and the cleaning component 30 transfers the dust on the filter screen 210 by adjusting its position, eliminating the need for manual disassembly and cleaning, thus improving cleaning efficiency.

[0128] 2. No separate dust collection device is required, avoiding the need for users to regularly disassemble the dust collection box to empty dust and debris, thus simplifying the structure of the filter cleaning components;

[0129] 3. Maintain continuous cleaning during the operation of the heat exchange equipment to prevent the air inlet from being without filter screen 210 during the cleaning process, which would require the machine to be stopped before cleaning can begin, thus improving the utilization efficiency of the heat exchange equipment.
