Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and specifically provides an indoor unit. Background Art

[0002] The existing air conditioner or its indoor unit unit (hereinafter referred to as "indoor unit") arranged in the conditioned room is usually provided with an air inlet and an air outlet. The exhaust or air supply device in the air conditioner draws the air in the conditioned room (which is usually called "return air") or fresh air from the outside into the air conditioner through the air inlet. The air flows through the heat exchanger arranged in the air conditioner and is cooled or heated. The cooled or heated air is then sent into the room through the air outlet. In the case where the air conditioner has at least cooling and heating functions, cold air (for example, in summer) or hot air (for example, in winter) can be blown out from the air outlet according to actual needs.

[0003] An air conditioner indoor unit with a functional module has been developed in the prior art. The functional module may be a humidifier, a purifier, a fresh air blower, etc. This indoor unit can not only enrich the functions of the air conditioner and improve the user experience, but also make full use of the space of the indoor unit and reduce space occupancy. Usually, this indoor unit is provided with an air outlet at its upper part and a receiving cavity at its lower part, and the functional module is arranged in the receiving cavity and can enter and exit the receiving cavity.

[0004] However, when the functional module is separated from the accommodating cavity, other components (such as electronic components, etc.) arranged in the accommodating cavity are exposed to the outside, and the user can directly observe or touch them from the opening of the accommodating cavity, which not only affects the aesthetics of the product but also may pose a risk of component damage.

[0005] Accordingly, the art needs a new technical solution to solve the above problems. Utility Model Content

[0006] In order to solve or improve to a certain extent the above-mentioned technical problem of the prior art, that is, the technical problem that the functional module of the indoor unit in the prior art will affect the aesthetics and safety of the product after being separated from the indoor unit, the utility model provides an indoor unit. The indoor unit comprises: a shell, in which a receiving cavity opening outward is provided; a functional module, which is configured to be inserted into or removed from the receiving cavity; and a shielding component, which is fixed to the shell and positioned in the receiving cavity, so that when the functional module is removed from the receiving cavity, the shielding component can cover part of the shell.

[0007] In the case of adopting the above technical solution, a shielding component positioned in the accommodating cavity is provided on the housing of the air conditioner, so that when the functional module is removed from the accommodating cavity, the shielding component can shield other components (such as electronic components) in the accommodating cavity, preventing the components from being directly exposed to the user's field of vision, thereby improving the aesthetics of the product. In addition, the shielding component can also play an isolating role, not only preventing the functional components from colliding with other components when entering and exiting the accommodating cavity and causing damage, but also preventing users (especially children) from directly contacting other components in the accommodating cavity, preventing personal injury, and improving the safety of the product.

[0008] In a specific embodiment of the indoor unit, the shielding component includes a base plate opposite to the opening and side plates extending from two vertical edges of the base plate toward the opening.

[0009] When the above technical solution is adopted, the arrangement of a base plate and two side plates can fully protect the area that may be hit when the functional module enters and exits the accommodating cavity, while providing multi-angle shielding and protection for other components in the accommodating cavity.

[0010] In a specific embodiment of the indoor unit, a flange is formed on a vertical edge of each of the side panels away from the base panel, and the flanges on the two side panels extend in opposite directions to each other.

[0011] When the above technical solution is adopted, the flange can better cooperate with the relevant components in the shell, so that the shielding component is more stable when connected to the shell.

[0012] In a specific embodiment of the indoor unit, a plurality of air inlet holes spaced apart from each other are provided on the base plate and / or the side plate, so that the air in the accommodating cavity can enter the functional module through the air inlet holes.

[0013] When the above technical solution is adopted, the air inlet hole facilitates smooth air intake of the functional module when it is accommodated in the cavity.

[0014] In a specific implementation of the above indoor unit, the diameter of the air inlet hole ranges from 3mm to 8mm.

[0015] When the above technical solution is adopted, the size of the air inlet hole is moderate, which can prevent debris from entering the functional module while ensuring sufficient air intake.

[0016] In a specific embodiment of the indoor unit, the shell includes a base, a main unit opposite to the base, and a support column arranged between the base and the main unit, and the base, the support column and the main unit together enclose the accommodating cavity.

[0017] When the above technical solution is adopted, the main machine is supported by support columns, which can make the installation of the main machine more stable.

[0018] In a specific implementation of the indoor unit, the number of the support columns is three, one of the support columns is close to the base plate, and the other two support columns are close to the two side panels respectively.

[0019] When the above technical solution is adopted, the three support columns are located at three different positions, so that the force on the main unit is more uniform and the installation is more stable.

[0020] In a specific embodiment of the indoor unit, a first fixing column extending vertically outward is formed on a side of the base plate away from the side panel, and a first fixing hole matching the first fixing column is formed on the support column close to the base plate; and / or a second fixing column extending vertically outward is formed on a side of each of the side panels away from the base plate, and a second fixing hole matching the second fixing column is formed on the support column close to each side panel.

[0021] When the above technical solution is adopted, the base plate and the support column are fixed by the connection between the first fixing column and the first fixing hole, so that the shielding component does not move in the opening direction. The two side panels are fixed to the corresponding support columns by the connection between the second fixing column and the second fixing hole, so that the shielding component does not move in the direction perpendicular to the side panels.

[0022] In the specific implementation of the indoor unit described above, a fixing lug extending in a direction away from the substrate is formed on a side of each flange away from the substrate, a third fixing hole is provided on the fixing lug, and a fourth fixing hole matching the corresponding third fixing hole is provided on the base.

[0023] When the above technical solution is adopted, the substrate and the base are fixed by the third fixing hole and the fourth fixing hole, thereby preventing the shielding component from moving along its height direction.

[0024] In a specific implementation of the indoor unit, the base plate, the side plate and the flange are integrally formed.

[0025] When the above technical solution is adopted, an integrated molding setting is adopted to simplify the manufacturing process and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] See also Figure 1-Figure 3 and Figure 6-Figure 7 The housing 110 includes a base 111, a main body 113 opposite to the base 111, and a support column 112 arranged between the base 111 and the main body 113, and the base 111, the support column 112 and the main body 113 together enclose a receiving cavity 114. Figure 1 and Figure 2In the orientation shown, the base 111 extends substantially horizontally. The base 111 can be arranged on a horizontal ground to stably support the entire indoor unit 100. The base 111 is provided with fourth fixing holes (not shown) near the left and right sides. The support column 112 is arranged on the base 111. In one or more embodiments, the number of the support columns 112 is 3. Figure 3 The three support columns 112 are respectively located on the left and right sides and the rear side of the base 111. Each support column 112 is configured to extend vertically upward from the base 111 to the main unit 113. The support columns 112 on the left and right sides are provided with second fixing holes 1121 close to the upper part; and the support column 112 on the rear side is provided with two first fixing holes (not shown in the figure). The accommodating cavity 114 has an opening facing the outside. Based on Figure 1 and Figure 2 In the orientation shown, the opening is located on the front of the housing 110 (facing the direction of the user).

[0043] It should be noted that the above-mentioned setting of the housing 110 is not unique, and those skilled in the art can select the specific structure of the housing 110 based on the specific application scenario. For example, the number of support columns 112 can also be set to other suitable numbers more or less than 3. The arrangement position of the support column 112 can also be adjusted according to actual needs. Alternatively, a guard plate (not marked in the figure) is also provided on the outside of each support column 112 to improve the stability and structural strength of the housing 110. Alternatively, the first fixing hole and the second fixing hole 1121 are not provided on the support column 112. Alternatively, the housing 110 may only include the support column 112 and the host 113. The support column 112 is placed on the ground, and the support column 112 supports the host 113. The ground, the support column 112 and the host 113 together enclose a hollow accommodating cavity 114.

Figure 2 The substrate 131 is facing the paper surface. On the side of the substrate 131 away from the side plate 132 ( Figure 5A first fixing column 1312 extending vertically outward (perpendicular to the direction of the substrate 131 toward the paper surface) is formed on the side of the substrate 131 shown in the middle. The number of the first fixing columns 1312 is two, and the two first fixing columns 1312 are respectively located near the upper side and the lower side. The two first fixing columns 1312 can be connected to the corresponding first fixing holes on the support column 112 to achieve the fixation between the substrate 131 and the support column 112, so that the shielding component 130 will not move along the opening direction (i.e., the front-to-back direction).

[0045] It should be noted that the above-mentioned configuration of the substrate 131 is not unique, and those skilled in the art can select the specific configuration of the substrate 131 based on the specific application scenario. Alternatively, the first fixing column 1312 is no longer provided on the substrate 131, or three, four or more first fixing columns 1312 are provided. Accordingly, the first fixing holes on the support column 112 are provided accordingly. Alternatively, the two first fixing columns 1312 can be provided at other positions on the substrate 131, as long as they can be connected to the first fixing holes.

[0046] See the attached Figure 2 , Figure 4-Figure 7 In one or more embodiments, the side panels 132 extend from two vertical edges of the base plate 131 toward the opening of the accommodating cavity 114 ( Figure 2 The side panels 132 are connected to the base plate 131. The portion where the side panels 132 are connected to the base plate 131 is arc-shaped, and the rest is a flat plate. A second fixing column 1321 extending vertically outward is formed on the side of each side panel 132 away from the base plate 131. The second fixing column 1321 is disposed near the upper portion of the side panel 132. The second fixing column 1321 can be connected to the corresponding second fixing hole 1121 on the support column 112 to achieve fixation between the two side panels 132 and the support columns 112 on the left and right sides, thereby preventing the shielding component 130 from moving in a direction perpendicular to the side panels 132 (i.e., the left and right direction).

[0047] Alternatively, the side panels 132 may be flat plates as a whole, and the side panels 132 and the base plate 131 may be connected at right angles, and one end of the side panels 132 connected to the base plate 131 may also be connected in a polygonal manner. Alternatively, the second fixing column 1321 may not be perpendicular to the base plate 131. Alternatively, the second fixing column 1321 may be arranged at other positions on the side panel 132, as long as it can be connected to the second fixing hole 1121. Alternatively, the number of the second fixing columns 1321 may also be two, three or more. Alternatively, the base plate 131 may not be provided, that is, the shielding component 130 only includes two side panels 132 opposite to each other or only includes one side panel 132. Alternatively, the shielding component 130 may also be configured to include a base plate 131 and one side panel 132.

[0048] In one or more embodiments, a plurality of air inlet holes 1311 spaced apart from each other are provided on both the base plate 131 and the side plate 132. The number and arrangement of the air inlet holes can be adjusted according to actual needs. In one or more embodiments, the diameter of the air inlet holes ranges from 3 mm to 8 mm. Through the air inlet holes 1311, the air in the accommodating cavity 114 (including the air entering the accommodating cavity 114 from the external environment) can enter the functional module 120 to ensure the smooth operation of the functional module 120. In addition, the moderate air inlet holes 1311 can also prevent debris from entering the functional module 120, thereby playing a role in dust prevention and filtering.

[0049] Alternatively, the diameter of the air inlet hole 1311 may be other suitable values ​​other than 3 mm-8 mm. Alternatively, the air inlet hole 1311 may be only provided on the base plate 131 , or only provided on the side plate 132 .

[0050] like Figure 4-Figure 7 As shown, in one or more embodiments, a flange 133 is formed on the vertical edge of each side plate 132 away from the base plate 131, and the flanges 133 on the two side plates 132 extend in opposite directions. That is, Figure 4 The flange 133 on the side plate 132 on the middle right side extends roughly to the right. Figure 4 The flange 133 on the side plate 132 on the left side of the center extends substantially to the left. A fixing lug 1331 extending in a direction away from the base plate 131 is formed on a side of each flange 133 away from the base plate 131. A third fixing hole 13311 is provided on the fixing lug 1331, and the third fixing hole 13311 and the fourth fixing hole on the base 111 are connected by screws to achieve fixation between the flange 133 and the base 111, thereby preventing the shielding component 130 from moving in its height direction (i.e., up and down direction).

[0051] Alternatively, the flange 133 may not be provided with a fixing lug 1331, or the fixing lug 1331 may be provided on only one of the flanges 133. Alternatively, other connection structures, such as a connection column, etc. may be provided on the flange 133 to replace the fixing lug 1331. Alternatively, the flange 133 may not be provided.

[0052] In one or more embodiments, the base plate 131 , the side plate 132 and the flange 133 are integrally formed, thereby simplifying the manufacturing process and improving production efficiency.

[0053] Alternatively, the base plate 131, the side plate 132 and the flange 133 may be processed separately and then fixed together. The fixing method includes but is not limited to welding.

[0054] like Figure 1As shown, in one or more embodiments, the functional module 120 has a substantially rectangular shape. Alternatively, the shape of the functional module 120 can also be set to other suitable shapes, such as cylindrical, etc. The functional module 120 is a combination of one or more of a humidifier, a purifier and a fresh air blower. Specifically, the functional module 120 can be a combination of a humidifier and a purifier, a purifier is arranged at the lower side of the humidifier, and the humidifier and the purifier are combined to form the functional module 120, so that the functional module 120 can simultaneously have the functions of humidifying and purifying the air. Alternatively, the functional module 120 can be a combination of a humidifier and a fresh air blower, a fresh air blower is arranged at the lower side of the humidifier, and the humidifier and the fresh air blower are combined to form the functional module 120, so that the functional module 120 can simultaneously have the functions of humidifying the air and providing fresh air for the room. Alternatively, the functional module 120 can be a combination of a purifier and a fresh air blower. Alternatively, the functional module 120 can also be a combination of the three devices of a humidifier, a purifier and a fresh air blower. The combination here is a simple stacking, and several devices can work independently. The specific combination method is the existing technology and will not be described here.
