Description

Technical Field

[0001] This utility model relates to a removable filter cleaning structure. Background Technology

[0002] An air conditioning drain pump is a type of drain pump. The common installation and use of air conditioning drain pumps is generally in central air conditioning systems. When a central air conditioning system is in use, the condensate formed during the exchange of hot and cold air between the air conditioning unit and the indoor unit will first drip into the water collection pan below the air conditioning unit. Subsequently, the drain pump on one side of the water collection pan will drain the condensate, thereby reliably discharging the condensate generated during the use of the central air conditioning system to the outside.

[0003] In the actual installation of central air conditioning systems, the process typically involves drilling holes with an impact drill (usually for mounting the indoor unit and the drip tray), peeling off the outer insulation of the power cord before wiring, and binding with insulating tape during wiring. Regardless of the step, some debris may fall into the drip tray (during wall drilling for the indoor unit and drip tray, small pieces of insulation from peeling off the power cord, or fragments of insulating tape from wiring, can also fall into the drip tray). When this debris falls into the drip tray, it will then enter the drain pump during drainage. Furthermore, dust or small flying or crawling insects that enter the air conditioner during use will also contribute to the condensate from the indoor unit, which will then enter the drip tray and subsequently the drain pump. These debris typically accumulate inside the drain pump. Once they accumulate to a certain extent, they can affect the normal operation of the pump, leading to reduced drainage efficiency or even complete pump malfunction. This can cause condensate in the drip tray to fail to drain in time, resulting in condensate buildup in the ceiling and making the central air conditioning system unreliable. Summary of the Invention

[0004] In view of the above shortcomings, this utility model provides a removable filter cleaning structure that can ensure the working reliability of the air conditioner drain pump and prevent the accumulation of debris from affecting the drainage efficiency or causing the pump body inside the air conditioner drain pump to stop working.

[0005] To achieve the above objectives, this utility model employs a removable filter cleaning structure, including a drawer base and a removable mechanism. The drawer base includes a removable rail, and the removable mechanism includes a stop edge distributed on the bottom side of the removable mechanism, a lifting part distributed on the top side of the removable mechanism, and a storage cavity distributed inside the removable mechanism. A filter is contained within the storage cavity. The storage cavity is used to store debris blocked by the removable mechanism, and the liquid entering the storage cavity flows through the mesh opening of the filter to the other side of the removable mechanism. The two sides of the removable mechanism are adapted to the removable rail. The sliding mechanism is inserted into the drawer seat by cooperating with the two sides of the sliding mechanism and the sliding rail. The stop edge of the sliding mechanism in the drawer seat extends to the bottom of the drawer seat, and the side of the stop edge that is away from the sliding mechanism is closely arranged with the inner side wall of the drawer seat. The sliding mechanism performs a sliding action along the two sides of the sliding mechanism on the sliding rail, and the stop edge forms a stop and limit for the debris in the storage cavity, and is used to make the debris in the storage cavity drag out to the outside of the drawer seat with the stop edge.

[0006] The present invention is further configured such that the drawer seat includes an upper drawer seat and a lower drawer seat, and the drawer slide rail includes an upper drawer slide rail distributed in the upper drawer seat and a lower drawer slide rail distributed in the lower drawer seat. The upper drawer slide rail and the lower drawer slide rail are arranged in abutment with each other, and the drawer slide mechanism is inserted into the lower drawer slide rail from the direction of the upper drawer slide rail.

[0007] The present invention is further configured such that the storage cavity includes a back baffle compartment distributed at the bottom of the cavity and a plurality of limiting blocks distributed at the bottom of the cavity and located on one side of the back baffle compartment. The back baffle compartment and the plurality of limiting blocks form a limiting space. The limiting space is used for embedding and limiting the filter screen, and the filter screen embedded in the limiting space has its periphery in contact with the periphery of the bottom of the storage cavity.

[0008] The present invention is further configured such that a pull-out stop portion is formed on the top side of the pull-out mechanism relative to the direction of the stop edge, and a pull-out stop groove adapted to the pull-out stop portion is formed on the side of the upper drawer seat relative to the side away from the lower drawer seat. The pull-out mechanism inserted into the drawer seat is limited in the drawer seat insertion stage by the limit of the pull-out stop portion in the pull-out stop groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: by incorporating a removable filter cleaning structure into two parts, namely a drawer seat and a removable mechanism, the drawer seat includes a removable rail, and the removable mechanism includes three parts: a stop edge distributed on the bottom side of the removable mechanism, a lifting part distributed on the top side of the removable mechanism, and a storage cavity distributed inside the removable mechanism; in addition, a filter screen is included and limited in the storage cavity. When the removable mechanism is fitted into the drawer seat, the stop edge on the removable mechanism can extend to the bottom of the drawer seat, and the side of the stop edge that is away from the removable mechanism is closely arranged with the inner wall of the drawer seat. Furthermore, when the removable filter cleaning structure is applied to the drain pump, the corresponding removable filter cleaning structure is distributed between the drain pump inlet and the drain pump body. That is, the drawer seat and the removable rail are both distributed on the drain pump casing. The removable mechanism on the drain pump extends from the cover of the pump casing to the bottom of the pump casing. At the same time, the stop edge of the removable mechanism extends with the removable rail to the bottom of the bottom casing. The storage cavity of the removable mechanism is distributed in the direction facing the drain pump inlet. Therefore, when the drain pump with the removable filter cleaning structure is used, if there are impurities in the condensate entering the drain pump through the inlet, the impurities can be blocked and filtered by the filter in the storage cavity. Therefore, users can periodically, or when the central air conditioning system experiences poor drainage or drainage malfunctions, pull out the pull-out mechanism of the removable filter cleaning structure along the pull-out rail. The stop edge then removes impurities from the storage chamber to the outside of the drain pump, facilitating convenient cleaning of debris inside the pump or prioritizing the removal of debris (avoiding the need for immediate disassembly and repair of the drain pump when poor drainage or drainage malfunctions occur). Furthermore, after the pull-out mechanism is removed, the filter can be removed, cleaned, and then reinstalled in the storage chamber. The removable filter structure prevents hard-to-clean areas that could lead to bacterial growth and ensures the safe operation of the drain pump. Attached Figure Description

Detailed Implementation

[0011] like Figure 1-12 As shown, a specific embodiment of this utility model is a removable filter cleaning structure, including a drawer base and a removable mechanism 1. The drawer base includes a removable rail. The removable mechanism 1 includes a stop edge 13 distributed on the bottom side of the removable mechanism 1, a lifting part 12 distributed on the top side 11 of the removable mechanism 1, and a storage cavity 14 distributed inside the removable mechanism 1. A filter 3 is limited in the storage cavity 14. The storage cavity 14 is used to accumulate debris blocked by the removable mechanism 1, and the liquid entering the storage cavity 14 flows to the other side of the removable mechanism 1 through the mesh opening 31 of the filter 3. The two sides of the removable mechanism 1 are adapted to the removable rail. The sliding mechanism 1 is inserted into the drawer seat by cooperating with the two sides of the sliding mechanism 1 and the sliding rail. The stop edge 13 on the sliding mechanism 1 placed in the drawer seat extends to the bottom of the drawer seat, and the side of the stop edge 13 that is away from the sliding mechanism 1 is closely arranged with the inner side wall of the drawer seat. The sliding mechanism 1 performs a sliding action on the sliding rail along the two sides of the sliding mechanism 1, and the stop edge 13 forms a stop and limit for the debris in the storage cavity 14, and is used to make the debris in the storage cavity 14 drag out to the outside of the drawer seat with the stop edge 13.

[0012] The removable filter cleaning structure comprises two parts: a drawer seat and a removable mechanism 1. The drawer seat contains a removable slide rail, while the removable mechanism 1 comprises three parts: a stop edge 13 distributed on the bottom side of the removable mechanism 1, a lifting part 12 distributed on the top side 11 of the removable mechanism 1, and a storage cavity 14 distributed inside the removable mechanism 1. In addition, a filter 3 is included and limited in the storage cavity 14. When the removable mechanism 1 is fitted into the drawer seat, the stop edge 13 on the removable mechanism 1 can extend to the bottom of the drawer seat, and the side of the stop edge 13 that is away from the removable mechanism 1 is closely arranged with the inner wall of the drawer seat. Furthermore, when the removable filter cleaning structure is applied to the drain pump 10, the corresponding removable filter cleaning structure is distributed between the inlet 103 of the drain pump 10 and the pump body of the drain pump 10. That is, the drawer seat and the removable rail are both distributed on the pump shell of the drain pump 10. The removable mechanism 1 on the drain pump 10 extends from the cover 101 of the pump shell to the bottom shell 102 of the pump shell. At the same time, the stop edge 13 of the removable mechanism 1 extends to the bottom of the bottom shell 102 along the removable rail. The storage cavity 14 of the removable mechanism 1 is distributed in the direction facing the inlet 103 of the drain pump 10. Therefore, when the drain pump 10 with the removable filter cleaning structure is used, if there are corresponding impurities in the condensate entering the drain pump 10 through the inlet 103, the corresponding impurities can be blocked and filtered by the filter 3 in the storage cavity 14. Therefore, users can periodically, or when the central air conditioning system experiences poor drainage or drainage failure, pull out the pull-out mechanism 1 of the pull-out filter cleaning structure along the pull-out rail. The stop edge 13 will then remove impurities from the storage cavity 14 to the outside of the drain pump 10, thus facilitating the cleaning of debris inside the drain pump 10 or prioritizing the removal of debris (avoiding the need for immediate disassembly and repair of the drain pump 10 when the central air conditioning system experiences poor drainage or drainage failure). In addition, after the pull-out mechanism 1 is pulled out, the filter screen 3 can be removed, cleaned, and then reinstalled in the storage cavity 14. By making the filter screen 3 a detachable structure, it is possible to avoid hard-to-clean hygiene dead corners that could lead to subsequent bacterial growth, and also ensure the safety of the drain pump 10 during use.

[0013] like Figure 3-10As shown, the drawer base includes an upper drawer base 2 and a lower drawer base 4. The drawer slide rails include an upper drawer slide rail 21 distributed within the upper drawer base 2 and a lower drawer slide rail 41 distributed within the lower drawer base 4. The upper drawer slide rail 21 and the lower drawer slide rail 41 are arranged in abutment. The design of the drawer slide mechanism 1 inserting into the lower drawer slide rail 41 from the direction of the upper drawer slide rail 21 is such that when the removable filter cleaning structure is applied to the pump housing of the drain pump 10, since the pump housing of a typical drain pump 10 involves two parts, the cover 101 and the bottom shell 102, the drawer base of the removable filter cleaning structure involved in this utility model is divided into an upper drawer base 2 and a lower drawer base 4. The drawer slide rails correspondingly involve the upper drawer slide rail 21 and the lower drawer slide rail 41, that is, the upper drawer base 2... The upper drawer rail 21 is correspondingly attached to the cover 101, while the lower drawer seat 4 and the lower drawer rail 41 are correspondingly attached to the bottom cover 102. Since the upper drawer rail 21 and the lower drawer rail 41 adopt a mutually abutting structure design, that is, when the cover 101 and the bottom cover 102 are closed, the upper drawer rail 21 and the lower drawer rail 41 can abut against each other, thereby ensuring the reliability of the removable filter cleaning structure of the present invention in the pump casing of the drain pump 10. At the same time, the design scheme of inserting the pull-out mechanism 1 into the lower drawer rail 41 from the direction of the upper drawer rail 21 is adopted, thereby ensuring that after the drain pump 10 is installed and used, its pull-out mechanism 1 can be easily pulled out and cleaned from the pump casing.

[0014] like Figure 3-10 As shown, the storage cavity 14 includes a back baffle compartment 141 distributed at the bottom of the cavity and several limiting blocks 142 distributed at the bottom of the cavity and located on one side of the back baffle compartment 141. A limiting space is formed between the back baffle compartment 141 and the several limiting blocks 142. The limiting space is used for embedding and limiting the filter screen 3. The filter screen 3 embedded in the limiting space has its periphery in contact with the periphery of the bottom of the storage cavity 14. This allows the filter screen 3 involved in the removable filter screen cleaning structure to be reliably installed in the removable mechanism 1. At the same time, it can also be easily disassembled in the subsequent cleaning stage.

[0015] like Figure 3-4 As shown in Figures 11-12, the top side 11 of the pull-out mechanism 1 has a pull-out stop portion 15 formed relative to the direction of the stop edge 13. The upper drawer seat 2 has a pull-out stop groove adapted to the pull-out stop portion 15 on the side away from the lower drawer seat 4. The pull-out mechanism 1, which is placed in the drawer seat, is limited by the pull-out stop portion 15 in the pull-out stop groove, thus forming a design that limits the pull-out mechanism 1 during the drawer seat insertion stage. This design ensures that when the pull-out filter cleaning structure is used on the drain pump 10, the pull-out mechanism 1 can be reliably limited on the pump casing of the drain pump 10, and also ensures the reliability of the design of this utility model.
