Technical Field

The invention relates to the technical field of air conditioners, in particular to a self-cleaning heat exchanger and an air conditioner.

Background

When the indoor unit of the air conditioner operates in a cooling or heating mode, air in the indoor environment enters the indoor unit along the air inlet of the indoor unit and is blown into the indoor environment again through the air outlet after heat exchange of the heat exchange plates, in the process, impurities such as dust, large particles and the like mixed in the indoor air can also enter the indoor machine along with the air flow of the inlet air, although the dustproof filter screen arranged at the air inlet of the indoor unit can filter most of dust and particles, but a small amount of fine dust is not completely blocked and filtered, and with the long-term use of the air conditioner, the dust will gradually deposit and adhere to the surfaces of the heat exchanger fins, and since the dust covering the outer surfaces of the heat exchanger is less thermally conductive, it directly affects the heat exchange between the heat exchange fins and the indoor air, so that the indoor unit needs to be cleaned regularly to ensure the heat exchange efficiency of the indoor unit.

Generally, a cleaning method of an indoor unit of an air conditioner in the prior art mainly comprises two modes of manual cleaning and self-cleaning of the air conditioner, wherein the manual cleaning mode is mainly completed by manually disassembling a filter screen of the indoor unit and manually dedusting a heat exchanger by a user or a maintenance worker, and the process is complex, time-consuming and labor-consuming; the air conditioner is self-cleaned mainly by using the frost condensation-defrosting operation of the air conditioner to clearly strip off dust on the heat exchanger by using condensed frost, but the frost condensation-defrosting operation involves switching of the operation mode of the air conditioner, so that the normal use of the air conditioner by a user is often influenced in the self-cleaning process. Therefore, there is still a need for a simple and convenient way to clean the heat exchanger.

As shown in fig. 1 to 4, the present invention provides a self-cleaning heat exchanger 1, the self-cleaning heat exchanger 1 comprises a plurality of heat exchange tubes 11 arranged at intervals, in an embodiment, the plurality of heat exchange tubes 11 are arranged in parallel at the same interval, here, adjacent heat exchange tubes 11 are communicated with each other through U-shaped tubes or bent tubes at the end portions, each heat exchange tube 11 can be regarded as a straight tube section except the U-shaped tubes or bent tubes at the end portions, in this embodiment, a space between the straight tube sections of two adjacent heat exchange tubes 11 is mainly defined as an air flow channel 12, and air flow can freely flow along the air flow channel 12.

It should be understood that the self-cleaning heat exchanger 1 to which the present invention is applied is not limited to the tube type self-cleaning heat exchanger 1 mentioned above, but other types of self-cleaning heat exchangers 1, such as a plate type, may also be used with similar solutions.

The self-cleaning heat exchanger 1 further comprises at least one set of stop members and cleaning elements 2. Wherein each set of the limiting members limits two or more adjacent heat exchange tubes 11 and the air flow channel 12 therebetween into a cleaning space 13, and the limiting members can be used for the air flow passing through the cleaning space 13 to pass through; one or more cleaning elements 2 are confined in a cleaning space 13, in which the cleaning elements 2 can be moved by an air flow.

Therefore, when the air current flows through the cleaning space 13, the cleaning piece 2 can be driven by the wind power of the air current to move irregularly in the cleaning space 13, when the cleaning piece 2 is in running contact with the outer surface of the self-cleaning heat exchanger 1, the cleaning piece 2 can rub the outer surface of the self-cleaning heat exchanger 1, so that dirt adhered to the outer surface can be rubbed clearly, and the effect similar to 'rag' can be achieved, therefore, when the air conditioner 3 runs in normal air supply, the self-cleaning operation of the self-cleaning heat exchanger 1 can be achieved by the cleaning piece 2.

In an alternative embodiment, taking two adjacent heat exchange tubes 11 as an example, the limiting member includes filter screens disposed at two ends of the extending direction of the airflow channel 12 and fixed to the heat exchange tubes 11 at two sides of the airflow channel 12 at each end, and the filter screens at two ends and the heat exchange tubes 11 at two sides enclose a cleaning space 13.

Here, the filter screen is not limited to be arranged around the heat exchange tubes 11 on both sides of the air flow channel 12, and if there are other gaps between the heat exchange tubes 11 on both sides that may cause the cleaning elements 2 to be detached, the filter screen may be additionally arranged for shielding, so as to ensure that the movement range of the cleaning elements 2 is always in the cleaning space 13.

In yet another alternative embodiment, the limiting member comprises a separate casing provided outside the adjacent two or more heat exchange tubes 11 and the air flow channel 12 therebetween to form the cleaning space 13; for example, for a self-cleaning heat exchanger 1, the individual housing may be designed to have an outer contour slightly larger than that of the self-cleaning heat exchanger 1, and the individual housing is sleeved on the self-cleaning heat exchanger 1, so that the housing is a space formed by locking all the heat exchange tubes 11 of the whole self-cleaning heat exchanger 1 and the air flow channels 12 therebetween as the cleaning space 13.

The cleaning piece 2 is arranged in the independent housing, and the wall of the independent housing is provided with a plurality of through holes for air flow to pass through so as to ensure that the air flow can flow in and out from the independent housing.

Here, the opening area of the through hole is smaller than the minimum sectional area of the cleaning member 2 to prevent the cleaning member 2 from being separated from the separate housing from the through hole, thereby ensuring the safety of the operation of the air conditioner 3 and avoiding the interference influence of the cleaning member 2 on other devices of the air conditioner 3.

In an alternative embodiment, the cleaning elements 2 are hollow structures made of a lightweight material, including but not limited to rubber or other lighter weight material, which reduces the individual weight of the cleaning elements 2 to make them more easily moved by the airflow in irregular movements.

Here, the shape of the cleaning member 2 is not limited to a spherical shape, and may be designed to be a square shape, an oval shape, or the like.

Preferably, in order to improve the friction dust removing effect, the outer surface of the cleaning elements 2 can be formed with irregular convex structures or designed with fluff, bristles and the like.

In the construction of the self-cleaning heat exchanger 1 shown in fig. 1 and 2, cleaning elements 2 of the same size are arranged in the cleaning space 13; in the structure of the self-cleaning heat exchanger 1 shown in fig. 3 and 4, the cleaning members 2 with different sizes may be disposed in the cleaning space 13, and here, because the sizes and volumes of the cleaning members 2 are different, the contact positions and contact areas of the cleaning members 2 with different sizes when contacting the outer surface of the self-cleaning heat exchanger 1 are also different, and the cleaning members 2 with smaller volumes may rub some small gaps of the self-cleaning heat exchanger 1 and dust in the small space clearly, so as to ensure the overall cleaning effect of the self-cleaning heat exchanger 1.

Fig. 5 is a schematic structural view of the air conditioner 3 of the present invention according to an exemplary embodiment.

As shown in fig. 5, the present invention further provides an air conditioner 3, the air conditioner 3 includes a housing 31, an air duct 32 formed inside the housing 31, a fan 33 disposed in the air duct 32, and an air outlet 34, the air conditioner 3 is further provided with any one of the self-cleaning heat exchangers 1 disclosed in the foregoing embodiments, and the self-cleaning heat exchanger 1 is disposed in the air duct 32.

In an alternative embodiment, the bottom of the cleaning space 13 is provided with a ball storage bin communicating with the cleaning space 13, which can be used as a receiving space for a plurality of cleaning elements 2 at the time of air conditioning shutdown, and as a dust collecting bin for dust cleared by the cleaning elements 2.

Specifically, one of the cleaning spaces 13 defined by the stopper member shown in the foregoing embodiments is an approximately rectangular space, and a ball storage box with an open top is provided at the bottom of the rectangular space; when the air conditioner is operated, airflow flows through the cleaning space 13, the cleaning piece 2 is driven by wind power to move from the ball storage box to the cleaning space 13, and the outer surface of the self-cleaning heat exchanger 1 is subjected to friction dust removal in the moving process; when the air conditioner is stopped, the cleaning pieces 2 move to the ball storage box below under the action of gravity again.

Preferably, the wall of the ball storage box is provided with a plurality of air holes communicated with the air duct 32 of the air conditioner 3, so that when the air current flows through the air duct 32, a part of the air current can enter the wall through the air holes, and thus, the cleaning element 2 can move from the ball storage box to the cleaning space 13 more easily.

Here, the opening area of the air hole is smaller than the minimum cross-sectional area of the cleaning piece 2, so that the cleaning piece 2 is prevented from being separated from the air hole and being discharged out of the ball storage box, the operation safety of the air conditioner 3 is guaranteed, and the interference influence of the cleaning piece 2 on other devices of the air conditioner 3 is avoided.

In an alternative embodiment, the air conditioner 3 is further provided with a ball storage passage, which is provided inside the air conditioner 3 and extends to a service opening of a cabinet of the air conditioner 3, and a ball storage box is provided in the ball storage passage and can be moved into or out of the cabinet through the ball storage passage and the service opening.

Specifically, be equipped with the maintenance mouth on air conditioner 3's the casing, extend into this storage ball passageway to air conditioner 3's inside along the maintenance mouth, be equipped with the slide rail in the storage ball passageway, store up the ball case and remove on the slide rail, like this, store up the ball case and can realize its immigration and remove the operation with the structural style of similar "drawer" to convenience of customers is to the change of cleaning member 2 and the clearance of the dust of collection.

In an alternative embodiment, the air conditioner 3 further comprises: the controllable shielding piece is used for conducting or blocking a communication path between the ball storage box and the cleaning air conditioner 3; in this embodiment, the shielding member is a shielding plate disposed at the top opening of the ball storage box, and the shielding plate is controlled by the driving device to move between a first position where the shielding plate does not shield the top opening and a second position where the shielding plate shields the top opening, so as to achieve the operation of connecting or disconnecting the communication path.

The air conditioner further includes a controller that controls the shutter to perform an operation of conducting or blocking. In this embodiment, the controller controls the operation of the shutter mainly by controlling the operation of the driving means.

For example, the shielding plate is provided with a rack extending along a connecting line direction between a first position and a second position, the driving device is a motor, the end part of a crankshaft of the motor is provided with a gear meshed with the rack, and when the motor runs in the forward direction, the motor drives the shielding plate to move from the first position to the second position through the meshing and matching of the gear and the rack; when the motor runs in the reverse direction, the shielding plate moves from the second position to the first position. Therefore, the controller can realize the operation control of the shielding piece by controlling the running direction of the motor.

In this embodiment, the specific operation of the controller may be performed according to an instruction input by a user, for example, in a shutdown state of the air conditioner, the cleaning element is completely located in the ball storage box, and at this time, the blocking element blocks the communication path; in the running process of the air conditioner, if a first instruction for starting self-cleaning is not received, the shielding piece still blocks the communication path, and at the moment, although airflow flows through the cleaning space, the cleaning piece is limited in the ball storage box, so that the self-cleaning heat exchanger cannot be cleaned by the cleaning piece at the moment; when a first instruction of starting self-cleaning is received, the shielding piece is communicated with the communication path, and at the moment, the airflow can drive the cleaning piece to move into the cleaning space so as to remove impurities such as dust on the self-cleaning heat exchanger by utilizing the irregular movement of the cleaning piece.

When a second command to exit self-cleaning is received, the air conditioner can recover the cleaning members in the cleaning space in two ways: one is to control the fan of the air conditioner to pause, at the moment, as no air flow driven by the fan passes through, the cleaning piece can be gradually settled back into the ball storage box under the action of gravity, after the cleaning piece is completely recovered, the shielding piece blocks the communication path and controls the operation of the restarting fan; and the other is to temporarily not respond to the second instruction, the air conditioner still maintains normal operation, and after the air conditioner is turned off and the fan stops operating, the second instruction is responded, at the moment, the cleaning piece is settled back into the storage ball box, and the shielding piece blocks the communication path.

Here, the specific operation of the controller may also be adjusted according to the operation state of the air conditioner itself, for example, the self-cleaning operation may be controlled to be performed only in a set period in the cooling mode of the air conditioner operation, because there is much dust adhered to the self-cleaning heat exchanger in the high temperature weather in summer of the cooling mode operation, and therefore, the air conditioner generates a first instruction for performing cleaning of the self-cleaning heat exchanger through the set period, so that the cleanliness of the self-cleaning heat exchanger may be effectively ensured, the user experience may be improved, and the damage influence of the low temperature environment on the outer surface of the self-cleaning heat exchanger on the cleaning member may be reduced.

And controlling the self-cleaning operation not to be executed in the air-conditioning operation heating mode, wherein the reason is that the temperature of the outer surface of the self-cleaning heat exchanger is higher in the air-conditioning operation heating mode, and for cleaning pieces made of rubber and other materials, the high temperature easily causes the problems of melting deformation and the like of the cleaning pieces, so that the self-cleaning operation is not executed in the air-conditioning operation heating mode, the service life of the cleaning pieces is ensured, and the problem that the melted cleaning pieces are adhered to the outer surface of the self-cleaning heat exchanger can be avoided.

In an optional embodiment, the air conditioner further comprises a magnetic refrigeration heat exchange device and a refrigerant pipeline; the refrigerant pipeline is respectively connected with the magnetic refrigeration heat exchange device and the heat exchanger to form a circulation loop.

The heat exchange chamber 102 is a hollow chamber surrounding a part of the magnetic work bed 101, and the magnetic work bed 101 and the heat exchange chamber 102 are close to each other but do not contact each other. The refrigerant pipe 103 is communicated with the heat exchange cavity 102, and the driver is connected with the magnetic working medium bed 101 and drives the magnetic working medium bed 101 to rotate by taking the circular central axis as the axis. Therefore, when the magnetic working medium body 101 rotates around the center of the circular ring as an axis under the driving of a driver (not shown), the heat exchange cavity 102 still remains static, the fixed position of the heat exchange cavity 102 can be an excitation area, and at this time, the refrigerant in the heat exchange cavity 102 continuously absorbs the cold energy released by the magnetic working medium which is continuously excited due to the rotation of the magnetic working medium bed 101, so that the low-temperature refrigerant is conveyed out through the refrigerant pipe 103; the heat exchange cavity 102 may also be fixed in the demagnetization area, and at this time, the refrigerant in the heat exchange cavity 102 continuously absorbs the heat released by the magnetic working medium that is demagnetized continuously due to the rotation of the magnetic working medium bed 101, so that the high-temperature refrigerant is conveyed out through the refrigerant pipe 103. A controllable bracket can also be arranged and is fixedly connected with the heat exchange cavity 102, the heat exchange cavity 102 is positioned in the excitation area when low-temperature refrigerant is needed, and the heat exchange cavity 102 is positioned in the demagnetization area by the controllable bracket when high-temperature refrigerant is needed. The magnetic body is fixed and static, the magnetic working medium rotates relative to the magnetic body, the area of the magnetic working medium bed 101 close to the magnetic body is an excitation area, the area of the magnetic working medium bed far away from the magnetic body is a demagnetization area, a pipeline is arranged, a refrigerant is arranged in the pipeline, the refrigerant can continuously flow through the pipeline in a circulating way to enter the heat exchange cavity to exchange heat with the magnetic working medium in the excitation area, and the released cold energy is taken away, so that the refrigeration effect is realized; the heat exchange cavity 102 can also be arranged in the demagnetization area to take away heat released by the magnetic medium in the demagnetization area, so that the heating effect is realized. Therefore, the flow of the refrigerant is not required to be controlled by arranging the valve body, and the cold quantity or the heat quantity released by the magnetic working medium can be continuously taken away by the refrigerant, so that the defects of pause, alternation and the like in the conventional magnetic refrigeration system are overcome, the heat exchange efficiency is improved, and the energy consumption is reduced.

The heat exchange chamber 202 is a hollow cavity surrounding a partial region of the magnetic media bed 201, and the magnetic media bed 201 and the heat exchange chamber 202 are close to each other but do not contact each other. The refrigerant pipe 203 is communicated with the heat exchange cavity 202, the driver 206 is connected with the magnetic work bed 201 through the connecting rod 207 and drives the magnetic work bed 201 to rotate by taking a circular central axis of the magnetic work bed 201 as an axis, the driver 206 is arranged at the axis of the magnetic work bed 201, the connecting rod 207 extends to the magnetic work bed 201 from the driver 206 along the radial direction, the connecting point of the connecting rod 207 and the magnetic work bed 201 can be on the inner ring side wall of the magnetic work bed 201, can be on the top surface or the bottom surface of the circular ring surface of the magnetic work bed 207, and can even be connected to the outer ring side wall of the magnetic work bed 207, however, no matter how the connecting rod 207 is connected with the magnetic work bed 201, the heat exchange cavity 202 needs to be correspondingly provided with a passage, so that the connecting rod 207 which synchronously rotates can not be blocked at all when the magnetic work bed 201 rotates. When the magnetic working medium body 201 rotates by taking the center of the circular ring as an axis under the driving of the driver 206, the heat exchange cavity 202 still keeps static, although the fixed position of the heat exchange cavity 202 is an excitation area, the cold medium in the heat exchange cavity 202 continuously absorbs the cold energy released by the magnetic working medium which is continuously excited due to the rotation of the magnetic working medium bed 201, so that the low-temperature cold medium is conveyed out through the cold medium pipe 203; however, it should be understood that the heat exchange cavity 202 may be fixed in the demagnetization area, and in this case, the refrigerant in the heat exchange cavity 202 will continuously absorb the heat released by the magnetic medium that is demagnetized continuously due to the rotation of the magnetic medium bed 201, so as to transport the high temperature refrigerant out through the refrigerant pipe 203. A controllable bracket may also be provided, the bracket is fixedly connected to the heat exchange cavity 202, the heat exchange cavity 202 is positioned in the excitation area when a low-temperature refrigerant is required, and the bracket is controlled to position the heat exchange cavity 202 in the demagnetization area when a high-temperature refrigerant is required. The magnetic body is fixed and static, the magnetic working medium rotates relative to the magnetic body, the area of the magnetic working medium bed 201 close to the magnetic body is an excitation area, the area of the magnetic working medium bed far away from the magnetic body is a demagnetization area, a pipeline is arranged, a refrigerant is arranged in the pipeline, the refrigerant can continuously flow through the pipeline in a circulating way to enter the heat exchange cavity to exchange heat with the magnetic working medium in the excitation area, and the released cold energy is taken away, so that the refrigeration effect is realized; the heat exchange cavity 202 can also be arranged in the demagnetization area to take away the heat released by the magnetic medium in the demagnetization area, thereby realizing the heating effect. Therefore, the flow of the refrigerant is not required to be controlled by arranging the valve body, and the cold quantity or the heat quantity released by the magnetic working medium can be continuously taken away by the refrigerant, so that the defects of pause, alternation and the like in the conventional magnetic refrigeration system are overcome, the heat exchange efficiency is improved, and the energy consumption is reduced.

Because the compartment 303 makes the magnetic working media isolated regionally, on one hand, the loss of heat between the magnetic working media can be reduced, on the other hand, the utilization rate of the heat can be improved, and the energy consumption is reduced.

Therefore, in the refrigeration pipeline or the heating pipeline, the refrigerant can respectively carry out continuous heat exchange in the corresponding heat exchange cavity, the heat exchange efficiency is improved, and the energy consumption of the system is effectively reduced.
