Abstract
Description
Technical Field
[0001] This invention relates to the field of air conditioning cleaning technology, and more specifically, to an indoor air conditioning unit and an air conditioner. Background Technology
[0002] Currently, even if a filter is installed at the air inlet of an air conditioner to block the air flow after it has been idle for a long time, the air conditioner is not completely sealed. There will be a lot of impurities inside. When the air conditioner is turned on directly, these impurities will be blown into the room, which is detrimental to the indoor environment and the health of the user.
[0003] However, disassembling the air conditioner into parts and then cleaning the indoor unit is also quite troublesome and wastes a lot of time. Summary of the Invention
[0004] The problem solved by this invention is how to conveniently clean the indoor unit of an air conditioner to prevent impurities inside from being blown into the room after the unit has not been used for a long time.
[0005] To address the aforementioned problems, this invention provides an indoor air conditioning unit and an air conditioner, which can effectively improve the technical issues mentioned above.
[0006] This invention can be implemented as follows:
[0007] An embodiment of the present invention provides an indoor unit for an air conditioner, which includes a cross-flow fan, a cleaning component, and a collection box. The cleaning component and the collection box are both installed on the housing of the cross-flow fan, and the cleaning component is used to clean the impeller of the cross-flow fan; the collection box is used to collect the impurities cleaned out during the cleaning process of the cleaning component cleaning the impeller.
[0008] The cleaning mechanism enables automatic cleaning of the cross-flow fan impeller, eliminating the need for disassembly and making the cleaning process more convenient. Simultaneously, the collection box installed on the casing promptly collects the cleaned impurities, preventing them from being blown into the room by the airflow and ensuring clean indoor air.
[0009] Optionally, the collection box is movably disposed on the outer wall of the housing to switch between a dust collection position and a clearance position; when the collection box is in the dust collection position, the opening of the collection box is located on the side of the housing away from the impeller; when the collection box is in the clearance position, the outer wall of the housing blocks the opening of the collection box.
[0010] The collection box can slide relative to the housing, and the collection box is installed on the outer wall of the housing. In this way, when there is no need to perform dust collection operations, the collection box can be slid to the outer wall of the housing, and the opening of the collection box can be blocked by the outer wall. This not only avoids the collection box from affecting the normal air outlet operation, but also prevents the debris inside the collection box from overflowing.
[0011] Optionally, the indoor unit of the air conditioner further includes a gear and rack mechanism. The gear of the gear and rack mechanism is rotatably mounted on the housing, and the collection box is fixedly connected to the end of the rack of the gear and rack mechanism, so that when the gear rotates, the collection box slides relative to the housing through the rack. The collection box slides relative to the housing through the gear and rack mechanism, resulting in high motion stability.
[0012] Optionally, the housing is provided with the gear and rack mechanism at both ends along the axial direction of the impeller, and the two ends of the collection box are respectively fixedly connected to the end of the rack of one of the gear and rack mechanisms. The housing is provided with the gear and rack mechanism at both ends along the axial direction of the impeller, meaning that the indoor unit of the air conditioner includes at least two gear and rack mechanisms. The two ends of the collection box are respectively fixedly connected to the end of the rack of one gear and rack mechanism, thus the collection box slides relative to the housing through the combined action of the two gear and rack mechanisms.
[0013] Optionally, the housing includes an upper drainage section and a lower drainage section disposed opposite to each other, and an airflow channel communicating with the impeller is defined between the upper drainage section and the lower drainage section; the cleaning component and the collection box are both installed in the lower drainage section. The installation of both the cleaning component and the collection box in the lower drainage section facilitates the entry of swept-out impurities into the collection box along the lower drainage section, ensuring effective cleaning and collection.
[0014] Optionally, the indoor unit of the air conditioner further includes a dust baffle movably connected to the upper air intake section. The dust baffle is located within the airflow channel and guides the airflow towards the collection box when the cleaning component cleans the impeller. By providing a dust baffle at the upper air intake section, which is located within the airflow channel and guides the airflow towards the collection box, the problem of airflow carrying impurities flowing into the room along the upper air intake section and causing a decrease in indoor air quality is prevented, further ensuring the cleaning and collection effect.
[0015] Optionally, the collection box extends along the axial direction of the impeller and from one end of the air outlet of the housing to the other. The collection box extending from one end of the air outlet to the other ensures effective collection of impurities carried in the airflow flowing out from the air outlet along the axial direction of the impeller, resulting in good collection performance.
[0016] Optionally, the cleaning component includes a plate and bristles disposed at one end of the plate, the other end of the plate being connected to the housing; the plate has a connecting hole for impurities to pass through.
[0017] The cleaning component cleans the impeller with bristles. The plate on which the bristles are installed has connecting holes, which connect the spaces on both sides of the plate to prevent impurities cleaned by the bristles from being blocked by the plate and unable to be discharged from the air outlet along the casing.
[0018] Optionally, there are multiple connecting holes, with a plate between adjacent connecting holes. The sides of the plate are streamlined to guide airflow into the connecting holes. The streamlined shape of the plate guides the airflow carrying impurities toward the connecting holes, further reducing the obstruction effect of the plate.
[0019] An embodiment of the present invention also provides an air conditioner, which includes an indoor unit. The indoor unit includes a cross-flow fan, a cleaning component, and a collection box. The cleaning component and the collection box are both installed in the housing of the cross-flow fan, and the cleaning component is used to clean the impeller of the cross-flow fan; the collection box is used to collect impurities cleaned during the cleaning process of the cleaning component cleaning the impeller.
[0020] Since this air conditioner includes an indoor unit, it also allows for easy cleaning of the impeller, and the cleaned impurities can be effectively collected, preventing them from being blown into the room with the airflow and ensuring clean indoor air. Attached Figure Description

Detailed Implementation
[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0029] Figure 1 This is a schematic diagram of the structure of the indoor unit 100 of the air conditioner during normal operation, as provided in this embodiment. Figure 2 This is a structural diagram illustrating the cleaning process of the impeller 111 in the indoor unit 100 of the air conditioner provided in this embodiment. Please refer to the attached diagram. Figure 1 and Figure 2 This embodiment provides an indoor air conditioning unit 100, and correspondingly, an air conditioner (not shown in the figure) is provided.
[0030] The air conditioner includes an indoor unit 100 and an outdoor unit (not shown in the figure). The outdoor unit and the indoor unit 100 are connected to form a heat exchange medium circulation channel. In this way, heat exchange between the indoor and outdoor environments is achieved through the circulation of the heat exchange medium, so as to heat or cool the indoor environment as needed.
[0031] The indoor unit 100 of the air conditioner includes a cross-flow fan 110, a cleaning component 120, and a collection box 130. Both the cleaning component 120 and the collection box 130 are installed in the housing 112 of the cross-flow fan 110. The cleaning component 120 is used to clean the impeller 111 of the cross-flow fan 110, allowing for cleaning of the impeller 111 without disassembly, making the cleaning process more convenient. Simultaneously, the collection box 130 collects the cleaned impurities during cleaning, preventing them from being blown into the room with the airflow and ensuring clean indoor air.
[0032] The air conditioner indoor unit 100 provided in this embodiment will be further described below:
[0033] Please continue to refer to the reference. Figure 1 and Figure 2In this embodiment, the housing 112 includes an upper air intake portion 113 and a lower air intake portion 114 disposed opposite to each other. An airflow channel 115 communicating with the impeller 111 is defined between the upper air intake portion 113 and the lower air intake portion 114. Correspondingly, the air outlet 116 of the housing 112 is defined between the end of the upper air intake portion 113 away from the impeller 111 and the end of the lower air intake portion 114 away from the impeller 111. The airflow generated under the action of the impeller 111 is blown out of the cross-flow fan 110 from the air outlet 116 along the airflow channel 115.
[0034] Both the cleaning component 120 and the collection box 130 are installed in the lower airflow section 114. Dust and other impurities cleaned are collected in the collection box 130 after flowing along the lower airflow section 114. Specifically, the cleaning component 120 is rotatably installed on the side of the lower airflow section 114 facing the upper airflow section 113, meaning the cleaning component 120 is rotatably disposed within the housing 112. During normal operation of the indoor unit 100, the cleaning component 120 rotates to a position that fits against the inner wall of the lower airflow section 114 to reduce the obstruction of airflow by the cleaning component 120 and ensure effective airflow.
[0035] When cleaning the indoor unit 100 of the air conditioner, the cleaning component 120 is rotated clockwise (e.g., ...). Figure 1 and Figure 2 (From the perspective shown) the component rotates until it contacts the impeller 111. The slow rotation of the impeller 111 causes the cleaning component 120 to move relative to the impeller 111, thereby sweeping away impurities from various parts of the impeller 111. Furthermore, during this process, the rotation of the impeller 111 generates an airflow that flows through the airflow channel 115. This airflow carries away the cleaned impurities from the impeller 111, and they are collected in the collection box 130 as they flow with the airflow.
[0036] Optionally, the cleaning component 120 can be driven to rotate relative to the housing 112 by a driving component such as a motor. It is understood that in some other embodiments, a structure that drives the cleaning component 120 to move can also be provided as needed, enabling the cleaning component 120 to be positioned such that it is within the housing 112 during normal operation of the indoor unit 100. Figure 1 The position shown is flush with the inner wall of the lower drainage section 114. During air conditioner cleaning operations, the cleaning component 120 is located... Figure 2 The position shown is for contact with impeller 111, which can be used to clean impeller 111.
[0037] In this embodiment, the collection box 130 is movably disposed on the outer wall of the housing 112, thereby allowing the collection box 130 to switch between a dust collection position and a clearance position. Specifically, when the indoor unit 100 of the air conditioner is operating normally and discharging air, the collection box 130 moves to the clearance position. At this time, the collection box 130 is located on the outer wall of the housing 112, specifically on the side of the housing 112 away from the airflow channel 115, thus avoiding affecting the gas flow within the airflow channel 115. Simultaneously, the opening of the collection box 130 is blocked by the outer wall of the housing 112, preventing dust and other impurities from overflowing from the collection box 130 due to airflow. When the indoor unit 100 of the air conditioner is undergoing cleaning operations, the collection box 130 slides to the dust collection position. At this time, the opening of the collection box 130 is located on the side of the housing 112 away from the impeller 111, thereby collecting dust and other impurities blown out from the housing 112.
[0038] Specifically, the collection box 130 is a square box with an open top, installed on the outer wall of the lower guide portion 114, that is, on the side of the lower guide portion 114 away from the airflow channel 115. Thus, when the collection box 130 moves along the lower guide portion 114 to the end of the lower guide portion 114 away from the impeller 111 and extends beyond the outer wall of the lower guide portion 114, the collection box 130 is located outside the air outlet 116 of the housing 112. Because the impeller 111 rotates slowly during cleaning, the resulting airflow velocity is low, and dust and other impurities carried in the airflow blown out from the air outlet 116 can naturally fall into the collection box 130 from its opening (e.g., ...). Figure 2 (As shown).
[0039] Furthermore, the collection box 130 extends along the axial direction of the impeller 111, and one end of the air outlet 116 of the housing 112 extends to the other end. Specifically, the collection box 130 is elongated, its extension direction is parallel to the axial direction of the impeller 111, and the collection box 130 extends from one end of the lower guide portion 114 to the other end, so as to collect dust and other impurities blown out from the air outlet 116 defined by the lower guide portion 114, ensuring the collection effect.
[0040] Optionally, the indoor unit 100 of the air conditioner also includes a gear and rack mechanism 150, which is a structure including a gear 151 and a rack 152 that mesh with each other. The rack 152 can drive the gear 151 to rotate by sliding, or the rotation of the gear 151 can drive the rack 152 to slide. The gear 151 is rotatably mounted on the housing 112, and the collection box 130 is fixedly connected to the end of the rack 152. Thus, when the gear 151 rotates, the collection box 130 slides relative to the housing 112 with the rack 152, thereby realizing the sliding of the collection box 130 on the outer wall of the lower drain 114.
[0041] It should be noted that the structure and movement mode of the collection box 130 are not limited here. It is understood that in some other embodiments, the collection box 130 may be rotatably connected to the lower drainage part 114, or the linear movement of the collection box 130 relative to the lower drainage part 114 may be achieved by a structure such as a cylinder.
[0042] Specifically, the indoor unit 100 of the air conditioner also includes a drive component (not shown) that drives the gear 151 to rotate. Since both the collection box 130 and the cleaning component 120 need to move relative to the lower drain portion 114 to switch positions before cleaning, and both need to move relative to the lower drain portion 114 to reset after cleaning, the same drive component can be used to drive the gear 151 and the cleaning component 120 to rotate synchronously. It is understood that in some other embodiments, two independently configured drive components can also be used to drive the cleaning component 120 and the gear 151 to move respectively.
[0043] Figure 3 This is a structural schematic diagram of the indoor unit 100 of the air conditioner provided in this embodiment from another perspective. Please refer to the reference. Figures 1-3 Furthermore, the housing 112 is provided with a gear and rack mechanism 150 at both ends along the axial direction of the impeller 111, and the two ends of the collection box 130 are respectively fixed to the end of the rack 152 of the gear and rack mechanism 150.
[0044] Specifically, in this embodiment, there are two gear and rack mechanisms 150, namely a first gear and rack mechanism 153 and a second gear and rack mechanism 154. Both the first gear and rack mechanism 153 and the second gear and rack mechanism 154 are disposed on the outer wall of the lower guide portion 114 and located at both ends of the lower guide portion 114 along the axial direction of the impeller 111. The two ends of the collection box 130 are respectively fixed to the ends of the rack 152 of the first gear and rack mechanism 153 and the rack 152 of the second gear and rack mechanism 154. The first gear and rack mechanism 153 and the second gear and rack mechanism 154 have the same parameters and operating characteristics. Therefore, when the first gear and rack mechanism 153 and the second gear and rack mechanism 154 operate synchronously, they can drive the two ends of the collection box 130 to move synchronously relative to the lower guide portion 114.
[0045] Figure 4 This is a structural schematic diagram of the cleaning component 120 in the indoor unit 100 of the air conditioner provided in this embodiment. Please refer to the diagram for further details. Figures 1-4 In this embodiment, the cleaning component 120 includes a plate 121 and bristles 124 disposed at one end of the plate 121, and the other end of the plate 121 is connected to the housing 112. The plate 121 also has a connecting hole 122 for impurities to pass through.
[0046] Specifically, the plate 121 is a rectangular plate extending axially along the impeller 111 and is installed inside the housing 112. One end of the plate 121 in the width direction is rotatably connected to the lower drain portion 114, and the other end of the plate 121 in the width direction is provided with bristles 124. Thus, during cleaning operations, the rotation of the plate 121 drives the bristles 124 to contact the impeller 111. As the impeller 111 rotates slowly, the bristles 124 remove dust and other impurities from the impeller 111. At the same time, the bristles 124 are made of soft bristles to avoid damaging the surface of the impeller 111.
[0047] To avoid the problem that impurities falling into the side of the plate 121 away from the air outlet 116 cannot be discharged due to the space being divided by the plate 121, the plate 121 is provided with a connecting hole 122 for impurities to pass through. Thus, the impurities can pass through the connecting hole 122 under the drive of the airflow and be discharged from the housing 112 along the airflow channel 115 and collected in the collection box 130.
[0048] Figure 5 This is a partial structural cross-sectional view of the plate 121 in the indoor unit 100 of the air conditioner provided in this embodiment. Please refer to the diagram below. Figures 1-5 Furthermore, there are multiple connecting holes 122, and a plate 123 is provided between two adjacent connecting holes 122. The side of the plate 123 is streamlined to guide airflow into the connecting holes 122, further reducing the obstruction effect of the plate 121 on the airflow.
[0049] Specifically, the connecting hole 122 is square, and the plate 123 formed between two adjacent connecting holes 122 is also square. The sides of the plate 123 are streamlined to guide the airflow acting on the plate 123 toward the connecting hole 122, so that the airflow can flow more smoothly. Specifically, the plate 123 is generally thick in the middle and thin on both sides near the connecting hole 122.
[0050] Please continue to refer to the reference. Figures 1-5 In this embodiment, the indoor unit 100 of the air conditioner also includes a dust baffle 140 movably connected to the housing 112. The dust baffle 140 is located in the airflow channel 115 and is used to guide the airflow to the collection box 130.
[0051] Specifically, the dust baffle 140 is rotatably connected to the upper air intake 113 and is located on the side of the cleaning component 120 near the collection box 130 along the extension direction of the airflow channel 115. When the indoor unit 100 is operating normally, the dust baffle 140 adheres to the inner wall of the upper air intake 113, reducing its impact on airflow. When the indoor unit 100 is being cleaned, the dust baffle 140 rotates to a position that forms a certain angle with the inner wall of the upper air intake 113 and is tilted towards the collection box 130. Thus, the airflow along the upper air intake 113 flows downwards to the lower air intake 114 under the guidance of the dust baffle 140, ensuring the collection effect of the collection box 130 and preventing dust and other impurities cleaned from the impeller 111 from flowing into the room with the airflow, causing indoor air pollution. Optionally, the dust baffle 140 can be directly driven to rotate relative to the upper drainage part 113 by setting a separate driving component such as a motor. Understandably, other methods can also be used to achieve the rotation of the dust baffle 140.
[0052] The working principle of the air conditioner indoor unit 100 provided in this embodiment is as follows:
[0053] When the air conditioner indoor unit 100 has not been running for a long time and the impeller 111 needs cleaning, drive the impeller 111 to rotate slowly, while the various components in the air conditioner indoor unit 100 are located as follows: Figure 2 As shown, the cleaning component 120 rotates to the position where it contacts the impeller 111, the collection box 130 slides to the dust collection position, and the dust baffle 140 rotates to a position inclined towards the collection box 130. Thus, as the impeller 111 rotates, the cleaning component 120 brushes away the dust and other impurities on the impeller 111. The falling impurities flow along the airflow channel 115 with the airflow generated by the rotation of the impeller 111, and flow towards the collection box 130 under the action of the dust baffle 140, so as to ensure that the dust and other impurities carried in the airflow are collected and stored by the collection box 130, and prevent them from polluting the air after entering the room.
[0054] After cleaning is completed, all components are reset to their original positions. Figure 1 The location shown avoids affecting the airflow when the indoor unit 100 is running normally, and also prevents dust and other impurities in the collection box 130 from overflowing from the collection box 130 under the action of airflow.
[0055] The air conditioner indoor unit 100 and air conditioner provided in the embodiments of the present invention clean the impeller 111 by means of a cleaning component 120 rotatably connected to the lower air intake 114 of the cross-flow fan 110, thereby removing dust and other impurities from the impeller 111. As the cleaned impurities move with the airflow, they are guided by the dust baffle 140 to the collection box 130 at the lower air intake 114, ensuring the collection effect of the collection box 130 on the impurities and preventing the cleaned impurities from entering the room. This achieves automatic collection of cleaned impurities, is convenient to use, and provides good cleaning results.
[0056] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
