Description

Technical Field

[0001] The invention relates to the technical field of air source heat pump unit cleaning, in particular to a self-cleaning energy-saving air source heat pump unit. Background Art

[0002] Air source heat pump is an energy-saving device that uses high-level energy to make heat flow from low-level heat source air to high-level heat source. It is a form of heat pump that can convert low-level heat energy that cannot be directly used (such as heat contained in air, soil, and water) into usable high-level heat energy, thereby achieving the purpose of saving some high-level energy (such as coal, gas, oil, electricity, etc.).

[0003] Patent document with publication number CN115430225A discloses an air source heat pump combined heating and cooling unit, which is equipped with a protective case, a cold air duct, a hot air duct, an air outlet, a disc filter, a driving device, an auxiliary cleaning device, a safety screen, and a dust collection mechanism. When cold air or hot air is transported through the cold air duct or the hot air duct, the airflow will blow the driving device to rotate, and use the airflow to pass through the disc filter to filter out dust, dirt, hair and other impurities carried by the airflow in time;

[0004] At the same time, the rotating driving device can clean the impurities filtered out from the surface of the disc filter, and the rotating driving device will also exert top pressure on the auxiliary cleaning device, which helps to clean the impurities sticking to the surface of the disc filter again. At this time, the cleaned impurities are absorbed by the negative pressure generated by the dust suction mechanism. The interaction between the structures is utilized to make the entire device structure reasonable and simple, and easy to use. It can handle impurities such as dust, dust, and hair in time, and realize self-cleaning, and is not prone to blockage, so that the blown air is fresh, which is beneficial to human health, safe and reliable, and improves the performance of use.

[0005] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0006] The existing air source heat pump combined heating and cooling unit uses a driving device to clean impurities on the surface of the disc filter, so that the cleaned impurities are sucked by the dust collection mechanism, thereby realizing self-cleaning. However, when performing dust cleaning work, in order to ensure the dust cleaning effect, the air source heat pump unit needs to stop air intake, which is more troublesome in actual use and is not conducive to ensuring the continuous operation of the air source heat pump unit. Summary of the invention

[0007] In order to overcome the shortcomings of the existing air source heat pump combined heating and cooling units that, during the dust cleaning work, in order to ensure the dust cleaning effect, the air intake needs to be stopped, which is relatively troublesome in actual use, the embodiment of the present application provides a self-cleaning energy-saving air source heat pump unit, which controls the sliding plate seat to slide left and right between the limit base and the side wall of the cleaning component through an electric push rod, driving the two filters to change the position corresponding to the air inlet slot, and one filter moves to one side of the discharge slot, which can ensure that one side of the two air inlet slots is always filtered by the filter screen to filter dust and debris, and ensure that the dust and debris on the two filters are cleaned successively by the cleaning component without pausing the operation of the air source heat pump unit.

[0008] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0018] In one possible implementation, one end of the collecting cylinder is processed into an opening, and the end is connected and fixed to the inner wall of the protective chassis by bolts, so that the interior of the collecting cylinder is connected to the interior of the discharge slot, and the cleaning brush extends from the interior of the discharge slot and contacts a filter.

[0019] In a possible implementation, the cross-section of the guide cylinder is an isosceles trapezoid, and the bottom end of the guide cylinder is connected to a collecting bag.

[0029] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0030] Embodiment 1:

[0031] This embodiment introduces a specific structure of a self-cleaning energy-saving air source heat pump unit. Figure 1-Figure 5 As shown, it includes a protective chassis 1, a filter assembly 5 arranged on the outside of the protective chassis 1 and a cleaning assembly 6 arranged on the inside of the protective chassis 1, a cold air duct 2 is processed on one side of the protective chassis 1, a hot air duct 3 is processed on the other side of the protective chassis 1, a limiting base 4 is processed on the surface of the protective chassis 1, and drainage slots 7 are processed inside both ends of the limiting base 4, and two air inlet slots 8 are arranged between the two drainage slots 7;

[0032] Among them, the two air inlet slots 8 are both opened inside the limiting base 4, and the two air inlet slots 8 are respectively connected to one end of the cold air pipe 2 and the hot air pipe 3. During the air transportation process, the cold air can enter the cold air pipe 2 from one air inlet slot 8, and the hot air can enter the hot air pipe 3 from the other air inlet slot 8;

[0033] like Figure 2 and Figure 4 As shown, the filter assembly 5 includes a sliding plate seat 503, a receiving notch 502 is processed in the center of the sliding plate seat 503, and the inside of both ends of the sliding plate seat 503 are assembled and connected with a filter screen 501, and an electric push rod 504 is arranged inside the receiving notch 502, and the outside of the limit base 4 is buckled and connected with the limit cover 9;

[0034] The limiting cover 9 is assembled and connected to the protective chassis 1 by bolts on all sides, one end of the electric push rod 504 is assembled and connected to the inner wall of one end of the receiving slot 502, and the other end of the electric push rod 504 is assembled and connected to the surface at the center of the limiting base 4. When the electric push rod 504 is working, the sliding plate seat 503 can be controlled to slide between the limiting base 4 and the side wall of the cleaning component 6, driving the two filters 501 to change the position corresponding to the air inlet slot 8;

[0035] At the same time, because the distance between the far ends of the two filters 501 is equal to the distance between the centers of the two discharge slots 7, the two filters 501 correspond to the two air inlet slots 8 respectively. When one filter 501 blocks one side of a discharge slot 7, the other filter 501 exposes the other discharge slot 7 to the outside, thereby ensuring that one side of the two air inlet slots 8 is always filtered by the filter 501 to filter dust and debris, and ensuring that the dust and debris on the two filters 501 are cleaned successively.

[0036] By adopting the above technical solution:

[0037] The above-mentioned design encapsulates the filter assembly 5 between one side of the limit base 4 and the inner wall of the limit cover 9 by buckling the limit cover 9 on the outside of the limit base 4 on the surface of the protective chassis 1. When the electric push rod 504 is working, the sliding plate seat 503 is controlled to slide left and right between the limit base 4 and the side wall of the cleaning assembly 6, driving the two filters 501 to change the position corresponding to the air inlet slot 8, and one filter 501 moves to one side of the discharge slot 7, which can ensure that one side of the two air inlet slots 8 is always filtered by the filter 501 for dust and debris, and ensure that the dust and debris on the two filters 501 are cleaned successively by the cleaning assembly 6 without suspending the operation of the air source heat pump unit.

[0038] It is worth noting that both the electric push rod 504 and the cleaning component 6 work in a timing manner, and when the cleaning component 6 completes the cleaning of the surface of the filter 501, the electric push rod 504 controls the filter 501 to reset between one side of the limit base 4 and the inner wall of the limit cover 9, ensuring that one end of the filter 501 is spare, while the other end performs filtering work for a long time and is only active during the cleaning process, so that the spare end of the filter 501 will not be blocked.

[0039] Embodiment 2:

[0040] Based on Example 1, this example introduces the specific structure of the cleaning assembly 6, which includes a motor 606, a cleaning blade 601 is provided on one side of the motor 606, a cleaning brush 602 is provided on one side of the cleaning blade 601, and an adapter ring 604 is processed on one end of the cleaning brush 602;

[0041] The cleaning blade 601 is assembled and connected to one end of the rotating shaft of the motor 606, and the adapter ring 604 is assembled and connected to the center of the cleaning blade 601 by bolts. By making the axes of the adapter ring 604 and the cleaning blade 601 the same, when the motor 606 controls the cleaning blade 601 to rotate to perform air extraction, the cleaning brush 602 can clean the dust and debris on the filter 501;

[0042] Secondly, if Figure 5 As shown, a collecting cylinder 603 is arranged outside the motor 606, and a guide cylinder 605 is integrally formed at the bottom of the collecting cylinder 603. The cross section of the guide cylinder 605 is an isosceles trapezoid, and a collecting bag is connected to the bottom end of the guide cylinder 605. By assembling and fixing the motor 606 and the inner wall of the collecting cylinder 603 with a bracket, the motor 606 can control the cleaning fan blade 601 to rotate inside the collecting cylinder 603, so that the cleaned dust and debris are sucked into the inside of the collecting cylinder 603 and enter the inside of the guide cylinder 605 with the flowing air.

[0043] Secondly, if Figure 3 As shown, one end of the collecting tube 603 is processed into an opening, and the end is connected and fixed to the inner wall of the protective chassis 1 by bolts. By making the interior of the collecting tube 603 communicate with the interior of the discharge slot 7, the cleaning brush 602 can extend from the interior of the discharge slot 7 and contact with a filter net 501, thereby ensuring the cleaning effect.

[0044] By adopting the above technical solution:

[0045] The above-mentioned design is achieved by setting a collecting cylinder 603 with a motor 606, a cleaning fan blade 601, and a cleaning brush 602 on one side of the two discharge slots 7, and forming a guide cylinder 605 connected to a collecting bag at the bottom thereof. When the motor 606 controls the cleaning fan blade 601 to rotate inside the collecting cylinder 603, the dust and debris to be cleaned are sucked into the inside of the collecting cylinder 603, and enter the inside of the guide cylinder 605 with the flowing air, and fall into the collecting bag to complete the collection work. This is simple and convenient, which is beneficial to the air source heat pump unit to self-clean the dust accumulated on the filter 501 and ensure the air intake effect.

[0046] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
