Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, and more specifically, to an air inlet assembly and a heat exchange device. Background Technology

[0002] Air conditioners play a vital role in daily life, and the filter within them is responsible for filtering the air. Filters have a limited lifespan and require frequent replacement. Currently, the common installation method involves placing the filter on the control panel, with one side of the panel pivotally connected to the air intake plate. A handle is located on the other side of the panel, connecting to the air intake plate. To remove the filter, the handle is operated, causing the control panel to rotate relative to the air intake plate, opening it and allowing removal. However, this method is time-consuming and cumbersome. The control panel, especially the handle, often occupies a portion of the filter area for user operation. This increases the complexity and cost of the filter assembly. More importantly, the control panel obstructs the air intake of the indoor unit, directly reducing the air intake area. A reduced air intake area directly affects the airflow of the air conditioner, thus impacting its performance.

[0003] Therefore, as can be seen from the above, the existing technology has the problem that the filter structure of the air conditioner is complex and can easily block the air intake area. Utility Model Content

[0004] The main objective of this invention is to provide an air intake component and a heat exchange device to solve the problem that the filter structure of existing air conditioners is complex and easily obstructs the air intake area.

[0005] To achieve the above objectives, according to one aspect of the present invention, an air intake assembly is provided, comprising: an air intake panel having an air intake opening; an air intake grille disposed at the air intake opening, wherein at least one side of the air intake grille is spaced apart from the air intake panel to form an insertion port; and a filter element entering the air intake opening through the insertion port, wherein the filter element is disposed corresponding to the air intake grille and covers the air intake opening.

[0006] Furthermore, the air intake grille protrudes from the outer wall of the air intake panel.

[0007] Furthermore, in the direction perpendicular to the air inlet, the air outlet surface formed by the air outlet side of the air inlet grille is spaced apart from the outer wall of the air inlet panel.

[0008] Furthermore, the air intake assembly also includes a limiting rib, which is disposed on the air outlet side of the air intake grille, and a limiting groove is formed between the limiting rib and the air intake grille to constrain the edge of the filter element.

[0009] Furthermore, the limiting rib is located on the edge of the air intake grille away from the insertion port.

[0010] Furthermore, the filter element is detachably connected to one end of the air intake grille.

[0011] Furthermore, the filter element is snapped into the air intake grille.

[0012] Furthermore, one end of the filter element is a snap-fit ​​end. After the filter element is assembled in place at the air inlet, the snap-fit ​​end is located at the insertion port and snaps into the edge of the air inlet grille.

[0013] Furthermore, the snap-fit ​​end is provided with multiple snap hooks, which are spaced apart.

[0014] Furthermore, the outer wall of the air inlet panel has two oppositely arranged mounting ribs, which are respectively located on both sides of the air inlet, and the two ends of the air inlet grille are respectively connected to the two mounting ribs.

[0015] Furthermore, there are two sets of air intake grilles, which are arranged in a mirror image on the air intake panel.

[0016] According to another aspect of the present invention, a heat exchange device is also provided, comprising: the above-described air inlet assembly; and a housing, wherein the air inlet assembly is connected to the housing.

[0017] The present invention provides an air intake assembly comprising an air intake panel, an air intake grille, and a filter. The air intake panel has an air inlet, and the air intake grille is positioned at the air inlet. At least one side of the air intake grille is spaced apart from the air intake panel to form an insertion port. The filter enters the air inlet through the insertion port, and is positioned corresponding to the air intake grille and covering the air inlet. By creating an insertion port between the air intake grille and the air intake panel, when the filter needs to be installed, it is inserted between the air intake grille and the air inlet, thus quickly completing the installation. When the filter needs to be removed, it is pulled out in the opposite direction of insertion, without needing to disassemble the entire air intake panel or the entire air intake grille. The operation is simple, and the filter has a simple structure, requiring no additional operating panel or handle structure, which reduces obstruction of the air inlet. At the same time, this design also reduces the production cost of the air intake assembly and solves the problem of complex filter structures in existing air conditioners that easily obstruct the air intake area.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] To address the problem that the complex structure of filters in existing air conditioners easily obstructs the air intake area, this invention provides an air intake assembly and a heat exchange device. The heat exchange device includes the air intake assembly described below.

[0030] like Figures 1 to 7As shown, the air intake assembly includes an air intake panel 10, an air intake grille 20, and a filter element 30. The air intake panel 10 has an air inlet 11. The air intake grille 20 is disposed at the air inlet 11, and at least one side of the air intake grille 20 is spaced apart from the air intake panel 10 to form an insertion port 21. The filter element 30 enters the air inlet 11 through the insertion port 21, and is positioned corresponding to the air intake grille 20 and covers the air inlet 11.

[0031] By creating an insertion port 21 between the air inlet grille 20 and the air inlet panel 10, when the filter element 30 needs to be installed, it is inserted between the air inlet grille 20 and the air inlet 11 along the insertion port 21, thus quickly completing the installation of the filter element. When the filter element needs to be removed, it is pulled out in the opposite direction of insertion, without having to remove the entire air inlet panel 10 or the entire air inlet grille 20. The operation is simple and the structure of the filter element 30 is simple. It does not require an additional operating plate or handle structure, which can reduce the obstruction of the air inlet 11. At the same time, this setting method can also reduce the production cost of the air inlet assembly.

[0032] In this embodiment, the air intake grille 20 protrudes from the outer side wall of the air intake panel 10.

[0033] In this embodiment, in the direction perpendicular to the air inlet 11, the air outlet surface formed by the air outlet side 22 of the air inlet grille 20 is spaced apart from the outer side wall of the air inlet panel 10.

[0034] Specifically, the air outlet surface 22 is an arc-shaped surface, and the plane containing the outer wall of the air inlet panel 10 is closer to the air inlet 11 than the air outlet surface. An insertion opening 21 is formed between the air outlet surface and the outer wall of the air inlet panel 10. The size of the insertion opening 21 is adapted to the thickness of the filter element 30, or the insertion opening 21 is slightly larger than the thickness of the filter element 30. Furthermore, this spacing creates a buffer zone, which helps reduce wind resistance and improve airflow efficiency.

[0035] In this embodiment, the filter element 30 is a filter screen. The filter element 30 has a certain degree of flexibility and can produce a certain degree of deformation to facilitate installation. Of course, the filter screen can also be set on a frame with a certain degree of rigidity.

[0036] like Figure 7 As shown, the air intake assembly also includes a limiting rib 40, which is disposed on the air outlet side 22 of the air intake grille 20, and a limiting groove for constraining the edge of the filter element 30 is formed between the limiting rib 40 and the air intake grille 20.

[0037] Specifically, the extending direction of the limiting rib 40 is parallel to the bending direction of the air inlet grille 20, and the extending length of the limiting rib 40 is the same as the length of the air inlet grille 20 in the bending direction, so that the limiting groove can be adapted to the filter element 30. Of course, the limiting rib 40 can also be multiple segments, with multiple segments of the limiting rib 40 arranged at intervals along the bending direction of the air inlet grille 20 to form multiple limiting grooves, and the multiple limiting grooves cooperate to limit the filter element 30.

[0038] In this embodiment, the limiting rib 40 is integrally formed with the air inlet grille 20 or with the air inlet panel 10. Regardless of the method of arrangement, the limiting rib 40 is made of a material with a certain deformation capacity, so that it deforms when the filter element 30 enters or leaves the limiting groove.

[0039] In this embodiment, the limiting rib 40 is located on the side edge of the air inlet grille 20 away from the insertion port 21.

[0040] Specifically, the limiting ribs 40 and the insertion port 21 are located on opposite sides of the air inlet grille 20, thereby ensuring that the filter element 30 is limited by the limiting ribs 40 after entering between the air inlet grille 20 and the air inlet 11 through the insertion port 21. This prevents the filter element 30 from loosening due to vibration during operation of the heat exchange equipment, which could lead to filter element 30 failure. It also prevents the filter element 30 from shaking and generating vibration and noise, improving the user experience.

[0041] In this embodiment, the filter element 30 is detachably connected to one end of the air inlet grille 20.

[0042] Specifically, the filter element 30 and the air inlet grille 20 are connected by snap-fit ​​or screw bolts.

[0043] In this embodiment, the filter element 30 is snapped into the air inlet grille 20.

[0044] Specifically, the snap-fit ​​design not only simplifies the installation process of the filter element 30, but also ensures the stability of the filter element 30 during use, avoiding displacement caused by vibration or airflow impact.

[0045] like Figure 2 , Figures 4 to 5 As shown, one end of the filter element 30 is a snap-fit ​​end 31. After the filter element 30 is assembled at the air inlet 11, the snap-fit ​​end 31 is located at the insertion port 21 and snaps against the edge of the air inlet grille 20.

[0046] Specifically, the snap-fit ​​end 31 of the filter element 30 snaps into the edge of the air inlet grille 20 located at the insertion port 21, and the other end of the filter element 30 is limited by the limiting rib 40, thereby improving the limiting effect of the filter element 30.

[0047] In one embodiment of this application (not shown), the filter element 30 is provided with a raised rib on the side facing the air inlet grille 20, and a sliding groove is provided on the air inlet grille 20. The sliding groove is adapted to the raised rib, thereby further limiting the filter element 30 and preventing the filter element 30 from folding over, which would cause part of the air inlet 11 to be unblocked by the filter element 30, resulting in a decrease in the filtration effect or even failure. At the same time, this method can also improve the error tolerance during installation and improve the user experience.

[0048] like Figures 4 to 5 As shown, the snap-fit ​​end 31 is provided with multiple snap hooks 311, which are spaced apart.

[0049] Specifically, the hooks 311 are integrally formed with the top of the filter element 30. The multiple hooks 311 spaced apart improve the engagement between the hooks 311 and the air inlet grille 20 located at the insertion port 21. During installation, simply press the multiple hooks 311 downwards to engage the filter element 30 and the air inlet grille 20. Similarly, during disassembly, the hooks 311 are moved away from the air inlet grille 20 for quick removal. The hooks 311 have a certain degree of deformation capability, thus facilitating engagement.

[0050] In another embodiment of this application (not shown), the hook 311 is disposed in the middle or other position of the filter element 30. The hook 311 is pivotally connected to the filter element 30. When the filter element 30 is inserted along the insertion port 21, the hook 311 is rotated to avoid the air inlet grille 20. After installation, the hook 311 is rotated to complete the engagement with the air inlet grille 20.

[0051] like Figure 4 As shown, the outer wall of the air inlet panel 10 has two oppositely arranged mounting ribs 50, which are respectively arranged on both sides of the air inlet 11, and the two ends of the air inlet grille 20 are respectively connected to the two mounting ribs 50.

[0052] Specifically, the mounting ribs 50 extend along the length of the air inlet panel 10, and two mounting ribs 50 are set on opposite sides of the air inlet 11.

[0053] In this embodiment, there are two sets of air intake grilles 20, which are arranged in a mirror image on the air intake panel 10.

[0054] Specifically, two sets of air intake grilles 20 form two insertion ports 21 between the air intake panel 10 and the air intake grilles 20. The two air intake grilles 20 form a grille area. The two air intake grilles 20 are located at both ends of the grille area, and the two insertion ports 21 are set at both ends of the grille area along the length direction of the air intake panel 10.

[0055] Furthermore, the two air intake grilles 20 are located away from the two limiting ribs 40 at the center of the air intake 11.

[0056] In this embodiment, the air inlet panel 10 is vertically arranged, with two insertion ports 21 located at both ends of the vertical direction of the air inlet panel 10. Two filters 30 are provided, extending vertically into the insertion ports 21 from top to bottom and from bottom to top, respectively. Optionally, the two insertion ports 21 are horizontally arranged, and the two filters 30 are inserted horizontally.

[0057] This invention also provides a heat exchange device. The heat exchange device includes the aforementioned air inlet assembly and housing. The air inlet assembly is connected to the housing.

[0058] Specifically, the heat exchange equipment is an air conditioner, and the heat exchange equipment also includes a fan. The fan is installed inside the casing and the air is introduced and discharged through the fan. The air inlet panel 10 is installed on the casing and connected to the casing by screws.

[0059] Applying the technical solution of this utility model, the air inlet assembly includes an air inlet panel 10, an air inlet grille 20, and a filter element 30. The air inlet panel 10 has an air inlet 11, and the air inlet grille 20 is disposed at the air inlet 11. At least one side of the air inlet grille 20 is spaced apart from the air inlet panel 10 to form an insertion port 21. The filter element 30 enters the air inlet 11 through the insertion port 21, and is positioned corresponding to the air inlet grille 20 and covering the air inlet 11. By spaced apart between the air inlet grille 20 and the air inlet panel 10 to form an insertion port... When the filter element 30 needs to be installed, it is inserted between the air inlet grille 20 and the air inlet 11 along the insertion port 21, thereby quickly completing the installation of the filter element. When the filter element needs to be removed, it is pulled out in the opposite direction of insertion without disassembling the entire air inlet panel 10 or the entire air inlet grille 20. The operation is simple and the structure of the filter element 30 is simple. It does not require an additional operating plate and handle structure, which can reduce the obstruction of the air inlet 11. At the same time, this setting method can also reduce the production cost of the air inlet assembly.
