Currently, the common method for cleaning the fins is to use a four-way valve to switch directions for sterilization and cleaning. However, this cleaning method has poor cleaning effect, high energy consumption, and cannot effectively clean the dust on the fins. Utility Model Content

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0031] like Figures 1-3 As shown, this utility model provides a heat exchanger dust removal device, including a motor 100, a heat exchanger 300, an impactor 200, and a component to be impacted. The motor 100 is disposed on one side of the heat exchanger 300, and the impactor 200 is disposed on the motor shaft 110 of the motor 100 and is configured to rotate with the motor shaft 110. The component to be impacted 500 is connected to the heat exchanger 300 and is used to expand with the impactor 200 to transmit vibration to the heat exchanger 300.

[0032] The impactor 200 is connected to the motor shaft 110 and rotates with the motor shaft 110. As the motor shaft 110 rotates, the impactor 200 can impact the impactor 500 when it reaches a certain fixed position, thereby achieving periodic impact on the impactor 500, causing the heat exchanger 300 to vibrate, thereby removing dust from the heat exchanger fins and keeping the heat exchanger 300 clean.

[0033] It is understandable that the heat exchanger dust removal device sets an impact member 200 on the motor shaft 110 that rotates with the motor shaft 110, and configures the impact member 200 to periodically impact the impact member 500 as the motor shaft 110 rotates, thereby causing the heat exchanger 300 to vibrate, so as to vibrate and remove dust from the heat exchanger fins and keep the heat exchanger 300 clean.

[0034] At the same time, the impact component 500 is used to replace the heat exchanger 300 in the collision with the impact component 200, so as to avoid the impact component 200 directly colliding with the heat exchanger 300 and causing the heat exchanger 300 to deform.

[0035] Specifically, a connecting rod 600 is provided between the impactor 500 and the heat exchanger 300. One end of the connecting rod 600 is connected to the heat exchanger 300, and the other end of the connecting rod 600 is connected to the impactor 500. The connecting rod 600 and the impactor 200 are on the same plane.

[0036] Among them, the connecting rod 600 serves as a connecting component, ensuring that the impact component 500 can contact the impact component 200 even when the heat exchanger 300 is far from the motor shaft 110.

[0037] Furthermore, by controlling the opening of the throttling device, the temperature of the heat exchanger 300 can be reduced to below 0 degrees Celsius, causing the condensate on the surface of the heat exchanger 300 fins to freeze rapidly. After detecting the freezing on the surface of the heat exchanger 300 fins, the impact component 500 is made to impact the heat exchanger 300, thereby causing the ice on the surface of the heat exchanger 300 to break and fall off, so as to remove the dust and impurities on the surface of the heat exchanger 300 fins and achieve the effect of cleaning the heat exchanger.

[0038] In some embodiments, the impactor 500 is configured to switch between a first state and a second state. When the impactor 500 is in the first state, the impactor 200 can impact the impactor 500 as the motor shaft 110 rotates. When the impactor 500 is in the second state, the impactor 500 and the impactor 200 maintain a distance.

[0039] Specifically, by controlling the shape transformation and / or position change of the impactor 500, the impactor 500 can be switched between a first state and a second state, so that the impactor 500 can switch between a state in which it can collide with the impactor 200 and a state in which it maintains a distance from the impactor 200. In this way, the heat exchanger dust removal device can switch between a dust removal mode and a non-dust removal mode, avoiding the heat exchanger 300 from vibrating continuously, which would affect the functionality and installation stability of the heat exchanger 300.

[0040] It is understood that the heat exchanger dust removal device sets an impactor 200 on the motor shaft 110 that rotates with the motor shaft 110, and sets a target impactor 500 that can switch between a first state and a second state. The target impactor 500 is connected to the heat exchanger 300. When the two need to collide, the target impactor 500 is in the first state, and then the motor shaft 110 drives the impactor 200 to collide with the target impactor 500, thereby causing the heat exchanger 300 to vibrate and shake off the dust or impurities on the heat exchanger 300, thus improving the cleaning effect of the fins of the heat exchanger 300. When the heat exchanger 300 does not need to be cleaned, the target impactor 500 is in the second state, so that the target impactor 500 is away from the impactor 200.

[0041] Specifically, when the object to be impacted 500 is in the first state, it is moved to a certain position. When the object to be impacted 500 is in this position and the minimum distance between the object to be impacted 500 and the impactor 200 is less than or equal to 0, the impactor 200 can rotate to the impact position and collide with the object to be impacted 500, causing the object to be impacted 500 to shake or vibrate. This causes the heat exchanger 300 to vibrate or shake, thereby cleaning and removing dust from the fins of the heat exchanger 300. When the object to be impacted 500 is in the second state, and the minimum distance between the object to be impacted 500 and the impactor 200 is greater than 0, the impactor 200 will not collide with the object to be impacted 500 when it moves to the impact position, and the heat exchanger 300 can operate normally. The impact position is the closest point between the impactor 200 and the object to be impacted 500.

[0042] In some embodiments, the impact member 500 includes a telescopic sub-member 510 and an impact member 520. One end of the telescopic sub-member 510 is connected to the heat exchanger 300, and the other end of the telescopic sub-member 510 is connected to the impact member 520. The telescopic sub-member 510 is used to drive the impact member 520 to move between a first position and a second position. When the impact member 520 is in the first position, the impact member 500 is in a first state. When the impact member 520 is in the second position, the impact member 500 is in a second state.

[0043] The telescopic component 510 is used to drive the impact component 520 to move between a first position and a second position. When the impact component 520 is in the first position, the impactor 200 can impact the impact component 520 when it rotates to the impact position, thereby causing the heat exchanger 300 to vibrate or shake. When the impact component 520 is in the second position, the impact component 5020 and the impactor 200 in the impact position are kept apart, that is, they will not collide even when they are at the minimum distance, so as not to affect the operation of the heat exchanger 300.

[0044] In some embodiments, the telescopic sub-component 510 may be an electric telescopic rod, and the sub-component to be impacted 520 may be a block structure or a spherical structure. The electric telescopic rod can be used to extend and retract the sub-component to be impacted 520 between a first position and a second position.

[0045] Among them, the block structure or spherical structure of the sub-component 520 to be impacted is a solid structure to ensure that the sub-component 500 to be impacted has sufficient strength to be impacted more than 200 times with the impactor.

[0046] In some embodiments, the telescopic component 510 includes an electromagnetic coil 511 and an elastic component 512, the impact component 520 is a first magnetic component, the electromagnetic coil 511 is connected to the heat exchanger 300, the impact component 200, the first magnetic component, the elastic component 512 and the electromagnetic coil 511 are arranged along the same plane, one end of the elastic component 512 is connected to the electromagnetic coil 511, and the other end of the elastic component 512 is connected to the first magnetic component.

[0047] When the electromagnetic coil 511 is energized, it becomes magnetic and can attract the first magnetic component, causing the compression elastic component 512 to move toward the electromagnetic coil 511.

[0048] The fact that the impact member 200, the first magnetic member, the elastic member 512, and the electromagnetic coil 511 are arranged along the same plane can ensure that the impact member 200 can collide with the first magnetic member in the first position when it rotates.

[0049] When both the impact member 500 and the impact member 200 are arranged horizontally, when the impact member 500 is in the first state, the elastic member 512 is in a state that is neither compressed nor stretched, and the impact member 520 is in the first position. When the impact member 500 needs to be switched to the second state, the electromagnetic coil 511 is energized, causing the first magnetic member to compress the elastic member 512 and move it toward the electromagnetic coil 511 until it contacts or approaches the electromagnetic coil 511, so that the second magnetic member is in the second position. When the impact member 500 needs to be switched from the second state to the first state, the power supply to the electromagnetic coil 511 is cut off, and the elastic force of the elastic member 512 is used to send the first magnetic member to the first position.

[0050] Among them, the elastic element 512 is a spring.

[0051] In some embodiments, the telescopic component 510 includes a battery coil and a guide rod, the impact component 520 is a first magnetic component, the electromagnetic coil 511 is connected to the heat exchanger 300, the battery coil and the guide rod are arranged vertically, the first magnetic component passes through the guide rod and can slide on the guide rod at a first position and a second position, the guide rod is located above the impact component 200, when the first magnetic component needs to be in the first position, the current to the electromagnetic coil 511 is disconnected, so that the first magnetic component slides from the second position to the first position under the action of gravity; when the first magnetic component needs to be in the second position, the electromagnetic coil 511 is energized, so that the electromagnetic coil 511 attracts the first magnetic component, so that the first magnetic component moves against gravity toward the electromagnetic coil 511 to the second position; the second position can be the position where the first magnetic component is connected to the electromagnetic coil 511, or the position where the first magnetic component is away from the first position and close to the electromagnetic coil 511. When the first magnetic component leaves the first position, the minimum distance between the first magnetic component and the impact component 200 is greater than 0.

[0052] Specifically, one end of the connecting rod 600 is connected to the heat exchanger 300, the other end of the connecting rod 600 is connected to the electromagnetic coil 511, the elastic element 512 is connected to the electromagnetic coil 511 at the same end of the connecting rod 600, and the first magnetic element is connected to the end of the elastic element 512 away from the electromagnetic coil 511.

[0053] In some embodiments, the impact member 200 is provided with a sound-absorbing layer on the side facing the member 500 to be impacted.

[0054] Understandably, adding a sound-absorbing layer to the impactor 200 can reduce the noise of the collision between the impactor 200 and the object to be impacted 500. Generally, the sound-absorbing layer can be formed by sound-absorbing cotton covering the impactor 200.

[0055] In some embodiments, a sound-absorbing layer is provided on the side of the impactor 500 facing the impactor 200.

[0056] Understandably, placing a sound-absorbing layer on the impactor 500 can reduce the noise of the collision between the impactor 200 and the impactor 500. Generally, the sound-absorbing layer can be formed by sound-absorbing cotton covering the impactor 200.

[0057] In some embodiments, the impactor 200 is provided with a sound-absorbing layer on the side facing the impactor 500, and the impactor 500 is provided with a sound-absorbing layer on the side facing the impactor 200.

[0058] In some embodiments, the impact element 200 is an eccentric element.

[0059] It is understandable that by setting the impactor 200 as an eccentric component, the eccentric force can be used to increase the impact force of the impactor 200 on the impactor 500, thereby increasing the vibration or shaking amplitude of the heat exchanger 300 and improving the dust removal effect.

[0060] Among them, the distance between the end of the eccentric part that is at the largest distance from the motor shaft 110 and the part to be impacted 500 is the minimum distance between the two.

[0061] Specifically, the impact component 200 consists of a connecting rod 210 and an impact block 220. The connecting rod 210 is connected to the motor shaft 110. The connection position of the connecting rod 210 and the motor shaft 110 is located between the end and the middle of the connecting rod 600. The impact block 220 is located at the end where the distance between the connecting rod 210 and the motor shaft 110 is the largest.

[0062] In some embodiments, the heat exchanger dust removal device further includes a centrifugal fan 400, which is connected to a motor shaft 110 so that the motor 100 drives the centrifugal fan 400 to rotate, and the heat exchanger 300 is disposed on one side of the centrifugal fan 400.

[0063] The motor shaft 110 is connected to the shaft hole of the centrifugal fan 400. The impact member 200 is generally set between the motor 100 and the centrifugal fan 400. When the motor 100 drives the centrifugal fan 400 to rotate, it can drive the impact member 200 to rotate. When it is necessary to remove dust from the heat exchanger 300, the impact member 500 is in the first state, so that the impact member 200 can impact the impact member 500 when it rotates with the motor shaft 110, thereby causing the heat exchanger 300 to vibrate.

[0064] It is understandable that using the motor shaft 110 that drives the centrifugal fan 400 as a vibration source can save the cost of setting up a separate motor 100.

[0065] In some embodiments, the heat exchanger 300 includes at least a first sub-heat exchanger, a second sub-heat exchanger, a third sub-heat exchanger, and a fourth sub-heat exchanger, which are arranged around the centrifugal fan 400; each of the first, second, third, and fourth sub-heat exchangers is connected to a corresponding impact member 500.

[0066] Understandably, ceiling-mounted air conditioners typically vent air in four directions, with multiple sub-heat exchangers arranged around the centrifugal fan 400 to ensure uniform air temperature in all directions. To ensure effective cleaning and dust removal for each sub-heat exchanger, an impactor 500 is installed on each sub-heat exchanger. As the impactor 200 rotates with the motor shaft 110, it collides with the impactor 500 of each sub-heat exchanger in turn, causing each sub-heat exchanger to shake and remove dust.

[0067] Specifically, each sub-heat exchanger is spaced at the same distance from the centrifugal fan 400. Since the motor shaft 110 is connected to the motor shaft 110 hole of the centrifugal fan 400, and the motor shaft 110 is located at the central axis of the centrifugal fan 400, the distance between the impact member 500 on each sub-heat exchanger and the motor shaft 110 is the same when the second state is in which state.

[0068] In some embodiments, the present invention also provides an indoor unit, which includes the heat exchanger dust removal device described above. Since the indoor unit includes the heat exchanger dust removal device, that is, includes some or all embodiments of the heat exchanger dust removal device, the air conditioner has the beneficial effects of some or all embodiments of the heat exchanger dust removal device, which will not be described in detail here.

[0069] In some embodiments, the present invention also provides an air conditioner that includes the above-mentioned heat exchanger dust removal device. Since the air conditioner has the above-mentioned heat exchanger dust removal device, that is, includes some or all of the embodiments of the above-mentioned heat exchanger dust removal device, the corresponding air conditioner has the beneficial effects of some or all of the embodiments of the above-mentioned heat exchanger dust removal device.

[0070] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the contents of the present utility model specification and drawings under the application concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
