Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an indoor air conditioning unit and an air conditioner. Background Technology

[0002] An air conditioner mainly consists of an indoor unit and an outdoor unit, which together provide cooling and / or heating. Over time, the indoor heat exchanger and indoor fan of the indoor unit accumulate dust, bacteria, and other harmful substances. Although some air conditioners on the market currently have high-temperature sterilization functions, they cannot remove dust. Dust removal currently relies primarily on manual disassembly and cleaning, which is time-consuming, labor-intensive, and expensive.

[0003] Therefore, how to achieve dust removal and cleaning of indoor air conditioners is an urgent problem that the industry needs to solve. Utility Model Content

[0004] This utility model provides an indoor air conditioning unit and an air conditioner to solve the problems of time-consuming, labor-intensive and expensive manual cleaning of indoor air conditioning units in the prior art.

[0005] The first aspect of this utility model provides an indoor unit for an air conditioner, comprising:

[0013] Multiple brushes are installed on the side of the connecting rod; the multiple brushes are arranged at intervals along the circumference of the connecting rod.

[0014] According to the air conditioner indoor unit provided by this utility model, the side of the connecting rod is formed by splicing a brushed side and a brushless side, and the brushed side and the brushless side are respectively located on both sides of the central axis of the connecting rod; a plurality of brushes are arranged at intervals on the brushed side.

[0015] According to the air conditioner indoor unit provided by this utility model, the widths of two adjacent brushes are different.

[0016] According to the air conditioner indoor unit provided by this utility model, when the cleaning component is in the second position, the end of the brush away from the connecting rod is inserted into the heat dissipation gap of the indoor heat exchanger.

[0017] According to the air conditioner indoor unit provided by this utility model, the depth to which the brush is inserted into the heat dissipation gap is not less than 2mm.

[0018] According to the air conditioner indoor unit provided by this utility model, the indoor heat exchanger includes:

[0042] The following is combined with Figures 1 to 7 The heat pump system provided by this utility model is described in detail.

[0043] A specific embodiment of the first aspect of this utility model provides an indoor unit for an air conditioner. The indoor unit includes an indoor heat exchanger 110, an indoor fan 120, and a cleaning component 130. Along the front-to-back direction, the indoor fan 120 is arranged behind the indoor heat exchanger 110; the cleaning component 130 includes a cleaning assembly 131; the cleaning assembly 131 has a first position and a second position; in the first position, the cleaning assembly 131 is separated from the indoor fan 120 and the indoor heat exchanger 110; in the second position, the cleaning assembly 131 contacts the indoor fan 120 and / or the indoor heat exchanger 110 for cleaning the indoor fan 120 and / or the indoor heat exchanger 110.

[0044] In this embodiment, by providing a cleaning component 131 with a first position and a second position, in the second position, the cleaning component 131 contacts the indoor fan 120 and / or the indoor heat exchanger 110 for cleaning the indoor fan 120 and / or the indoor heat exchanger 110, eliminating the need for manual disassembly of the indoor air conditioner for cleaning, thus solving the problems of time-consuming, labor-intensive, and expensive manual cleaning. In the first position, the cleaning component 131 is separated from the indoor fan 120 and the indoor heat exchanger 110, which not only avoids affecting the rotation of the indoor fan 120 but also avoids affecting the heat exchange efficiency of the indoor heat exchanger 110. The design of separating the cleaning component 131 from the indoor fan 120 and the indoor heat exchanger 110 in the first position also avoids long-term contact between the cleaning component 131 and core components, reducing the risk of accidental friction or electrical interference.

[0045] Furthermore, in its second position, the cleaning component 131 directly contacts the indoor fan 120 and / or the heat exchanger, physically removing accumulated dust and dirt more thoroughly than simple airflow cleaning or electrostatic adsorption. The indoor fan 120 and / or the indoor heat exchanger 110 can be selectively cleaned to suit different levels of contamination. For example, the heat exchanger requires frequent cleaning to ensure heat exchange efficiency, while the indoor fan 120 may only require periodic cleaning, reducing unnecessary mechanical wear. The layered arrangement along the front-to-back direction saves lateral space and is suitable for small indoor unit housings.

[0046] like Figures 1 to 4 As shown, in some embodiments, the indoor heat exchanger 110 includes a heat exchanger body 111 and two tube sheets 112; the two tube sheets 112 are respectively installed at both ends of the heat exchanger body 111 to form an installation cavity 113 with an installation port on the rear side; an indoor fan 120 is installed at the installation port; and a cleaning component 131 is installed in the installation cavity 113.

[0047] In this embodiment, two tube sheets 112 are located at both ends of the heat exchanger body 111, forming a mounting cavity 113 with mounting ports. The indoor fan 120 is directly embedded in the mounting port, reducing the need for additional support structures and making the overall layout more compact. The indoor fan 120 is installed at the mounting port on the rear side of the indoor heat exchanger 110, ensuring that the airflow flows directly through the heat dissipation fins of the heat exchanger body 111, reducing airflow around or eddies and improving heat exchange efficiency. During maintenance, the indoor fan 120 can be directly disassembled without completely disassembling the indoor heat exchanger 110, reducing maintenance difficulty. The mounting cavity 113 formed by the tube sheets 112 can guide the airflow to be evenly distributed, avoiding excessively high or low local wind speeds and improving the uniformity of cooling and heating. The tube sheets 112 not only fix the heat exchanger body 111 but also serve as a support structure for the indoor fan 120, improving the overall rigidity and reducing vibration and noise during fan operation. The design of the mounting cavity 113 can provide a cleaning path for the cleaning component 131, making it easier for the cleaning component 131 to enter the fin gaps of the heat exchanger body 111 or the fan blades of the indoor fan 120, thereby improving the cleaning coverage.

[0048] Optionally, the indoor fan 120 can be installed at the mounting port using quick-installation methods such as clips or screws, simplifying the assembly process and reducing production costs.

[0049] Optionally, at least one of the two tube sheets 112 may be made of plastic.

[0050] Preferably, one of the two tube sheets 112 is a plastic tube sheet, and the other is a sheet metal tube sheet. A plastic tube sheet means it is made of plastic. A sheet metal tube sheet means it is made of sheet metal. The plastic tube sheet can reduce costs and overall machine weight, while the sheet metal tube sheet can provide structural support.

[0051] In some embodiments, the indoor fan 120 includes a fan body 121 and a drive motor 122. The fan body 121 is installed at the mounting port, and the drive motor 122 is located outside the mounting cavity of the indoor heat exchanger 110 and is installed on the sheet metal tube plate of the indoor heat exchanger 110. The drive end of the drive motor 122 passes through the sheet metal tube plate and is connected to the fan body 121 to drive the fan body 121 to rotate, thereby blowing cold or hot air around the heat exchanger body 111 into the room.

[0052] Optionally, the indoor fan 120 includes, but is not limited to, a cross-flow fan.

[0053] Specifically, the fan body 121 of the indoor fan 120 is installed at the mounting port on the rear side of the indoor heat exchanger 110. The drive motor 122 is located outside the mounting cavity 113 of the indoor heat exchanger 110 and is connected to the sheet metal tube sheet of the indoor heat exchanger 110. One end of the fan body 121 is connected to the drive motor 122, and the other end extends along the length of the heat exchanger body 111 and rotates with the plastic tube sheet of the indoor heat exchanger 110. The drive motor 122 drives the fan body 121 to rotate around its own central axis.

[0054] like Figure 1 and Figure 3 As shown, in some embodiments, the cleaning component 131 is located above or below the indoor fan 120. The cleaning component 131, arranged vertically, does not require additional front-to-back or left-to-right space of the indoor fan 120, allowing the entire unit to remain slim and lightweight.

[0055] Optionally, one end of the cleaning component 131 is rotatably engaged with one tube sheet 112 of the indoor heat exchanger 110, and the other end extends along the length of the indoor heat exchanger 110 and is rotatably engaged with another tube sheet 112 of the indoor heat exchanger 110.

[0056] For example, one end of the cleaning component 131 is rotatably engaged with the sheet metal tube sheet of the indoor heat exchanger 110, and the other end extends along the length of the indoor heat exchanger 110 and is rotatably engaged with the plastic tube sheet of the indoor heat exchanger 110.

[0057] It should be noted that the length of the indoor heat exchanger 110 can be in the left-right direction.

[0058] Optionally, the cleaning component 131 is located above the indoor fan 120. This prevents dust from falling onto the cleaning component 131 and avoids dust from re-accumulating on it.

[0059] like Figure 4 and Figure 5 As shown, in some embodiments, the cleaning component 130 further includes a drive component 132; the drive component 132 is connected to the cleaning component 131 and is used to drive the cleaning component 131 to switch between a first position and a second position, and is also used to drive the cleaning component 131 in the second position to move in order to clean the indoor fan 120 and / or the indoor heat exchanger 110.

[0060] In this embodiment, the driving component 132 facilitates the driving of the cleaning component 131. The driving component 132 can also be electrically connected to the controller to achieve automated control. The driving component 132 has two functions: firstly, it drives the cleaning component 131 to switch between a first position and a second position, enabling the cleaning component 131 to move and position; secondly, it drives the cleaning component 131 in the second position to ensure that the cleaning component 131 can complete the cleaning action. Using a single driving component 132 to simultaneously control the movement and positioning of the cleaning component 131 and its cleaning action simplifies the structure and reduces energy consumption and potential failure points associated with multiple motors.

[0061] Optionally, the drive assembly 132 includes a motor; the motor is located outside the mounting cavity 113 of the indoor heat exchanger 110. This avoids occupying space in the mounting cavity 113 and prevents the motor from generating heat that could affect cooling efficiency.

[0062] Optionally, the drive assembly 132 is mounted on the tube sheet 112 of the indoor heat exchanger 110.

[0063] Preferably, the drive assembly 132 is mounted to the plastic tube sheet of the indoor heat exchanger 110 by screws.

[0064] In some embodiments, the cleaning assembly 131 includes a connecting rod 1311 and a plurality of brushes 1312; one end of the connecting rod 1311 is rotatably engaged with the drive assembly 132, and the other end extends along the length of the indoor heat exchanger 110 and is rotatably engaged with the tube sheet 112 of the indoor heat exchanger 110; the plurality of brushes 1312 are mounted on the side of the connecting rod 1311; the plurality of brushes 1312 are arranged at circumferential intervals along the connecting rod 1311.

[0065] In this embodiment, the connecting rod 1311 extends along the length of the indoor heat exchanger 110, ensuring that the brush 1312 covers the entire lateral range of the indoor heat exchanger 110, reducing or even eliminating cleaning blind spots; it also avoids increasing the overall thickness of the unit. The circumferentially spaced brushes 1312 can be inserted into the fin gaps of the indoor heat exchanger 110 or the fan blade gaps of the indoor fan 120, achieving "crack-penetrating" cleaning during rotation, which is more effective than unidirectional brushes in removing deep-seated dust. The flexible material of the brush 1312 automatically conforms to the deformation of the fins during rotation, avoiding hard scratches. One end of the connecting rod 1311 is connected to the drive assembly 132, and the other end is supported on the tube sheet 112, forming a stable cantilever beam structure, reducing vibration and sway during high-speed rotation. The centrifugal force generated by the drive assembly 132 driving the cleaning assembly 131 to rotate can fling out the dust adsorbed by the brush bristles, reducing the accumulation of dirt on the brush 1312 itself.

[0066] Optionally, the connecting rod 1311 is located in the mounting cavity 113 and above the indoor fan 120. The left end of the connecting rod 1311 is rotatably engaged with the drive assembly 132 (e.g., a motor) via a coupling, and the right end of the connecting rod 1311 is rotatably engaged with the sheet metal tube plate 112 of the indoor heat exchanger 110.

[0067] It should be noted that "multiple" means at least two. In other words, the cleaning component 131 includes at least two brushes 1312.

[0068] Optionally, the cross-section of the connecting rod 1311 is at least one of a circle, an ellipse, or a polygon.

[0069] Preferably, the cross-section of the connecting rod 1311 is circular.

[0070] Optionally, the polygon includes at least one of a triangle, a quadrilateral, a pentagon, or a polygon.

[0071] In some embodiments, the side of the connecting rod 1311 is formed by splicing a brushed side and a brushless side, with the brushed side and the brushless side located on both sides of the central axis of the connecting rod 1311; a plurality of brushes 1312 are arranged at intervals on the brushed side.

[0072] In this embodiment, the brush 1312 is arranged on the brushed side, while the brushless side has no brush 1312, which enables directional cleaning, avoids ineffective friction, and extends the motor's lifespan. The brush 1312 can oscillate back and forth in conjunction with the motor's forward and reverse rotation, thereby cleaning the indoor fan 120 and / or the indoor heat exchanger 110. Compared to a full-circumference brush 1312, this reduces ineffective idling and lowers energy consumption. Compared to a full-circumference brush 1312, the weight of the entire cleaning component 130 can be reduced. The brushless side forms a low-resistance airflow channel, and the directional airflow generated during rotation can push the detached dust to a preset position, avoiding secondary adhesion caused by the turbulence created by the full-circumference brush 1312 in traditional designs.

[0073] The working process of the cleaning component 130 in this embodiment includes:

[0074] When cleaning of the indoor heat exchanger 110 is required, the drive assembly 132 (e.g., a motor) drives the cleaning assembly 131 from a first position to a second position. In the second position, the brush 1312 faces the indoor heat exchanger 110, and at this time, the brush 1312 is in contact with at least the heat exchange fins of the indoor heat exchanger 110. Then, the drive assembly 132 drives the connecting rod 1311 to rotate forward by a first angle, and the connecting rod 1311 drives the brush 1312 to rotate forward by a first angle. Immediately afterwards, the drive assembly 132 drives the connecting rod 1311 to rotate backward by a second angle, and the connecting rod 1311 drives the brush 1312 to rotate backward by a first angle. The brush 1312 oscillates repeatedly under the drive of the connecting rod 1311 and the drive assembly 132, thereby cleaning the heat exchange fins.

[0075] When cleaning of the indoor fan 120 is required, the drive assembly 132 (e.g., a motor) drives the cleaning assembly 131 from a first position to a second position. In the second position, the brush 1312 faces the indoor fan 120, and at this time, the brush 1312 is in contact with at least the fan blades of the indoor fan 120. Then, the drive assembly 132 drives the connecting rod 1311 to rotate forward by a second angle, and the connecting rod 1311 drives the brush 1312 to rotate forward by a second angle. Immediately afterwards, the drive assembly 132 drives the connecting rod 1311 to rotate backward by a second angle, and the connecting rod 1311 drives the brush 1312 to rotate backward by a second angle. The brush 1312 oscillates repeatedly under the drive of the connecting rod 1311 and the drive assembly 132, thereby cleaning the fan blades of the indoor fan 120. The first angle and the second angle may be equal or unequal, and the first angle and the second angle may be preset in the controller of the air conditioner indoor unit according to specific circumstances. In the specific embodiment of this utility model, the size of the first angle and the second angle is not limited.

[0076] When it is necessary to clean both the indoor heat exchanger 110 and the indoor fan 120 simultaneously, the drive assembly 132 (e.g., a motor) drives the cleaning assembly 131 from a first position to a second position. In the second position, the brush 1312 is in contact with at least one of the heat exchange fins and the fan blades. Then, the drive assembly 132 drives the connecting rod 1311 to rotate forward by a third angle, which in turn causes the brush 1312 to rotate forward by a third angle. Immediately afterwards, the drive assembly 132 drives the connecting rod 1311 to rotate backward by a third angle, which in turn causes the brush 1312 to rotate backward by a third angle. The brush 1312 oscillates repeatedly under the influence of the connecting rod 1311 and the drive assembly 132, thus cleaning the fan blades and the heat exchange fins. In other words, by adjusting the rotation angle of the motor, cleaning of at least one of the fan blades and the heat exchange fins can be achieved. The first angle and the third angle may be equal or unequal; the second angle and the third angle may be equal or unequal; the third angle may be preset in the controller of the indoor unit of the air conditioner according to specific circumstances; in the specific embodiments of this utility model, the size of the third angle is not limited.

[0077] When cleaning of the indoor heat exchanger 110 and indoor fan 120 is not required, the drive assembly 132 (e.g., motor) drives the connecting rod 1311 to return the brush 1312 to the first position, in which the brush 1312 is separated from the heat exchange fins and fan blades.

[0078] like Figure 6 and Figure 7 As shown, in some embodiments, the widths of two adjacent brushes 1312 are different. By setting brushes 1312 of different widths, the heat exchange fin gaps at different locations can be cleaned.

[0079] It should be noted that the radial direction along the connecting rod 1311 is the width direction of the brush 1312; the axial direction along the connecting rod 1311 is the length direction of the brush 1312.

[0080] Optionally, the longitudinal section of the brush 1312 is rectangular, and the widths of the longitudinal sections of two adjacent brushes 1312 are different.

[0081] In some embodiments, when the cleaning assembly 131 is in the second position, the end of the brush 1312 away from the connecting rod 1311 is inserted into the heat dissipation gap of the indoor heat exchanger 110. This ensures effective cleaning of the heat exchange fins.

[0082] Optionally, the brush 1312 can be inserted into the heat exchanger gap to a depth of not less than 2mm. This allows for deep cleaning of the heat exchange fins.

[0083] A specific embodiment of the second aspect of this utility model provides an air conditioner. This air conditioner includes the indoor unit of any of the above embodiments.

[0084] In this embodiment, since it includes the air conditioner indoor unit of any of the above embodiments, it has at least the above advantages, which will not be repeated here.

[0085] In some embodiments, the air conditioner further includes an outdoor unit; the outdoor unit is connected to the indoor unit to achieve cooling and / or heating. In other words, the air conditioner can perform both cooling and heating.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
