Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly, to an electric control box assembly and an air conditioner. Background Art

[0002] With the development of the economy, air conditioners are used more and more widely. An air conditioner generally includes an indoor unit and an outdoor unit. Among them, the main controller of the indoor unit is placed in an electric control box. In actual use, some main controllers include transformers, while some do not. As a result, the existing electric control boxes cannot meet the usage requirements of these two types of main controllers at the same time, and their versatility is poor. Summary of the Invention

[0003] The first object of the present invention is to provide an electric control box assembly to solve the technical problem that the existing electric control boxes cannot meet the usage requirements of main controllers with and without transformers at the same time, and their versatility is poor.

[0004] The electric control box assembly provided by the present invention includes an electric control box and a fireproof structure. The fireproof structure has a first state of being combined with the electric control box and a second state of being separated from the electric control box. An installation hole is provided on the side plate of the electric control box, and the installation hole is adapted to fix the transformer of the main controller. In the first state, the fireproof structure is configured to seal the installation hole.

[0005] By providing an electric control box assembly mainly composed of an electric control box and a fireproof structure, when a main controller without a transformer needs to be installed in the electric control box, the fireproof structure can be in the first state of being combined with the electric control box. At this time, the installation hole is sealed by the fireproof structure, blocking the communication between the inside of the electric control box and the outside air, thus effectively avoiding the situation where sparks jump out from the installation hole when the electric control box catches fire, reducing the potential safety hazards during the use of the electric control box, and ensuring the safety of the electric control box during use; when a main controller with a transformer needs to be installed in the electric control box, the fireproof structure can be in the second state of being separated from the electric control box, and the installation hole is used to fix the transformer of the main controller to achieve the installation of the transformer on the electric control box.

[0006] By providing a fireproof structure that can be selectively installed on the electronic control box assembly, when the electronic control box is used for installing a main controller without a transformer, the installation holes suitable for installing a transformer can be sealed with the fireproof structure. When the electronic control box is used for installing a main controller with a transformer, the transformer is fixed at the installation holes. Thus, the electronic control box can meet the usage requirements of both main controllers with and without transformers, has good versatility, does not require manufacturing two sets of molds for forming the electronic control box, and reduces the manufacturing cost of the molds. Moreover, during the production process, the situation of mixing two different structures of electronic control boxes can be avoided, thereby reducing the production cost and improving the production efficiency.

[0007] Furthermore, the fireproof structure is combined with the electronic control box by an adhesive bonding method. With this arrangement, it is convenient for the staff to connect the fireproof structure to the electronic control box, thereby improving the efficiency of setting the fireproof structure on the electronic control box.

[0008] Furthermore, the fireproof structure includes a tin foil paper layer and an adhesive layer. In the first state, the adhesive layer is adhesively fixed to the side plate. This form of setting the fireproof structure can not only achieve reliable fire prevention by using the tin foil paper layer, but also has a relatively low cost.

[0009] Furthermore, the fireproof structure is combined with the electronic control box by a snap connection method. With this arrangement, a detachable connection between the fireproof structure and the electronic control box is achieved, facilitating flexible switching of the same electronic control box in different usage scenarios.

[0010] Furthermore, the fireproof structure includes a sealing plate and a buckle fixedly arranged on the sealing plate. In the first state, the buckle is snap-fitted and fixed to the installation hole, and the sealing plate is closely attached to the side plate. By providing a buckle in the fireproof structure that is snap-fitted with the installation hole, the electronic control box itself can provide an installation position for the fireproof structure without the need to additionally provide a card hole for the buckle, thereby minimizing the modification of the electronic control box structure to the greatest extent and reducing the manufacturing cost.

[0011] Furthermore, the sealing plate includes a plate body and a sealing rib provided around the edge of the plate body. The sealing plate is closely attached to the side plate through the sealing rib. With this arrangement, the situation where the plate body is not closely attached to the side plate due to deformation tolerance can be avoided, thereby ensuring the sealing effect of the sealing plate.

[0012] Further, the buckle includes a first clamping arm and a second clamping arm which are opposite and spaced apart. A first clamping protrusion is provided on a surface of the first clamping arm facing away from the second clamping arm, and a second clamping protrusion is provided on a surface of the second clamping arm facing away from the first clamping arm. The first clamping arm and the second clamping arm can pass through the mounting hole and be clamped and fixed by the first clamping protrusion and the second clamping protrusion. This structural form of the buckle facilitates the installation and disassembly of the fireproof structure and can improve the installation and disassembly efficiency of the fireproof structure.

[0013] Further, the number of the mounting holes is multiple, and the number of the buckles is equal to the number of the mounting holes. The multiple buckles are respectively and correspondingly clamped and fixed to the multiple mounting holes. With such a setting, the connection reliability between the fireproof structure and the electric control box is ensured, so that the sealing plate can be closely attached to the side plate, enhancing the sealing effect of the fireproof structure.

[0014] Further, the fireproof structure is a fireproof plastic part or a sheet metal part. The fireproof structure in this material form has reliable fireproof performance and low cost.

[0015] Further, the fireproof structure is located outside the electric control box. With such a setting, it is convenient for the staff to connect and disassemble the fireproof structure and the electric control box.

[0016] The second object of the present invention is to provide an air conditioner to solve the technical problem that the existing electric control box cannot simultaneously meet the usage requirements of the main controller with a transformer and the main controller without a transformer, and has poor versatility.

[0017] The air conditioner provided by the present invention includes the above-mentioned electric control box assembly.

[0018] By arranging the above-mentioned electric control box assembly in the air conditioner, correspondingly, the air conditioner has all the advantages of the above-mentioned electric control box assembly, which will not be elaborated here one by one. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Figure 1 is a schematic structural view of the electronic control box 100, wherein the main controller of the air conditioner indoor unit is usually placed in the electronic control box 100 as shown in Figure 1 For ensuring electrical safety, the electronic control box 100 is designed for fire prevention, including flame retardancy of materials and sealing in terms of structure, etc.

[0033] For the main controller containing a transformer, on the side plate 110 of the electronic control box 100, there is a mounting hole 120, and the transformer is usually fixed to the side plate 110 of the electronic control box 100 through the mounting hole 120.

[0034] With the diversification of the main controller design, other design methods can be used to replace the original transformer, that is: the mounting hole 120 provided on the side plate 110 no longer needs to fix the transformer. At this time, the mounting hole 120 is in a vacant state, which makes the inner cavity of the electronic control box 100 communicate with the outside air, and the electronic control box 100 is in a non-sealed state. In this case, once the electronic control box 100 catches fire, sparks will jump out at the vacant mounting hole 120, igniting the materials outside the electronic control box 100 and causing a big fire, posing a huge potential safety hazard.

[0035] To avoid sparks from escaping at the mounting hole 120, the simplest and most direct way is to seal the mounting hole 120. However, this results in the inability to install the main controller with a transformer and the main controller without a transformer in the same electrical control box 100, thereby reducing the versatility of the electrical control box 100. Moreover, the two types of electrical control box structures mean that two sets of molds are required, resulting in a higher manufacturing cost. Additionally, for production, it is easy to mix the two different structures of electrical control boxes, leading to a higher production cost.

[0036] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following detailed description of the specific embodiments of the present invention will be provided in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] Figure 2 It is a schematic structural diagram of the electrical control box assembly provided in this embodiment (the fire prevention structure 200 is in the first state). As Figure 2 shown, this embodiment provides an electrical control box assembly, including an electrical control box 100 and a fire prevention structure 200. Specifically, the fire prevention structure 200 has a first state of being combined with the electrical control box 100 and a second state of being separated from the electrical control box 100. The side plate 110 of the electrical control box 100 is provided with a mounting hole 120, and the mounting hole 120 is adapted to fix the transformer of the main controller. Among them, in the first state, the fire prevention structure 200 is configured to seal the mounting hole 120.

[0038] By providing an electrical control box assembly mainly composed of an electrical control box 100 and a fire prevention structure 200, when it is necessary to install the main controller without a transformer in the electrical control box 100, the fire prevention structure 200 can be in the first state of being combined with the electrical control box 100. At this time, the mounting hole 120 is sealed by the fire prevention structure 200, blocking the communication between the inside of the electrical control box 100 and the outside air, thereby effectively avoiding the situation where sparks escape from the mounting hole 120 when the electrical control box 100 catches fire, reducing the potential safety hazards during the use of the electrical control box 100, and ensuring the safety of use of the electrical control box 100; when it is necessary to install the main controller with a transformer in the electrical control box 100, the fire prevention structure 200 can be in the second state of being separated from the electrical control box 100, and the mounting hole 120 is used to fix the transformer of the main controller to achieve the installation of the transformer on the electrical control box 100.

[0039] The electric control box assembly is provided with a fireproof structure 200 that can be selectively installed on the electric control box 100. When the electric control box 100 is used for installing a main controller without a transformer, the installation holes 120 suitable for installing a transformer can be sealed with the fireproof structure 200. When the electric control box 100 is used for installing a main controller with a transformer, the transformer is fixed at the installation holes 120. Thus, the electric control box 100 can meet the usage requirements of both main controllers with and without a transformer, has good versatility, and there is no need to manufacture two sets of molds for forming the electric control box 100, reducing the manufacturing cost of the molds. Moreover, during the production process, the situation of mixing two different structures of electric control boxes 100 can be avoided, thereby reducing the production cost and improving the production efficiency.

[0040] Please continue to refer to Figure 2 , in this embodiment, the fireproof structure 200 can be combined with the electric control box 100 by an adhesive bonding method.

[0041] The form in which the fireproof structure 200 is combined with the electric control box 100 by an adhesive bonding method facilitates the connection between the fireproof structure 200 and the electric control box 100 by the staff, thereby improving the efficiency of setting the fireproof structure 200 on the electric control box 100.

[0042] Figure 3 For Figure 2 is a schematic cross-sectional view of the fireproof structure 200 in. As Figure 3 shown, specifically, the fireproof structure 200 includes a tin foil paper layer 210 and an adhesive layer 220. In the first state, the adhesive layer 220 is adhesively fixed to the side plate 110.

[0043] This setting form of the fireproof structure 200 can not only achieve reliable fire prevention by using the tin foil paper layer 210, but also has a low cost, thereby reducing the cost of the electric control box assembly in this embodiment.

[0044] Please continue to refer to Figure 1 , two installation holes 120 are provided on the side plate 110 of the electric control box 100. Preferably, in this embodiment, the tin foil paper layer 210 is in a strip structure, and the length of the tin foil paper layer 210 can cover the two installation holes 120, and the shape of the adhesive layer 220 is the same as that of the tin foil paper layer 210.

[0045] With such a setting, one fireproof structure 200 can be used to seal the two installation holes 120 simultaneously, further improving the fixing efficiency of the fireproof structure 200 on the electric control box 100. Moreover, by providing the adhesive layer 220 in all areas of the tin foil paper layer 210, the reliable fixing of the tin foil paper layer 210 on the side plate 110 can be ensured, avoiding warping, and effectively reducing the risk of the tin foil paper layer 210 falling off from the electric control box 100.

[0046] Specifically, in this embodiment, the length of the tin foil layer 210 is between 70 - 90 mm, and the width is between 10 - 50 mm.

[0047] In other embodiments, a tin foil layer 210 can also be respectively pasted and fixed at each mounting hole 120.

[0048] It should be noted that in this embodiment, the fireproof structure 200 can be in the form of being combined with the electric control box 100 through the above-mentioned bonding method, but is not limited thereto, and other forms can also be adopted. Figure 4 This is a schematic structural diagram of another form of the electric control box assembly provided in this embodiment (the fireproof structure 200 is in the first state). Figure 5 For Figure 4 a schematic diagram of the fireproof structure 200 in Figure 6 For Figure 4 a cross-sectional structural view of the shown electric control box assembly. Specifically, as Figures 4 to 6 shown, the fireproof structure 200 is combined with the electric control box 100 through a snap connection method.

[0049] The form in which the fireproof structure 200 is combined with the electric control box 100 through a snap connection method realizes the detachable connection between the fireproof structure 200 and the electric control box 100. When the electric control box 100 needs to install a main controller without a transformer, only the fireproof structure 200 needs to be snap-fixed to the electric control box 100; when the electric control box 100 needs to install a main controller with a transformer, only the fireproof structure 200 needs to be removed from the electric control box 100. With such a setting, it is convenient for the same electric control box 100 to be flexibly switched in different usage scenarios.

[0050] Please continue to refer to Figures 4 to 6 , in this embodiment, the fireproof structure 200 can include a sealing plate 230 and a buckle 240 fixedly arranged on the sealing plate 230. Among them, in the first state, the buckle 240 is snap-fixed to the mounting hole 120, and the sealing plate 230 is closely attached to the side plate 110.

[0051] This setting form of the fireproof structure 200 can not only realize the reliable fixation of the fireproof structure 200 in the mounting hole 120, but also, after the buckle 240 is snap-fixed to the mounting hole 120, can utilize the close fit between the sealing plate 230 and the side plate 110 to realize the sealing of the mounting hole 120, and the sealing is reliable.

[0052] In addition, by providing a buckle 240 in the fireproof structure 200 that is snap-fitted with the mounting hole 120, the electric control box 100 itself can provide a mounting position for the fireproof structure 200, without the need to additionally provide a card hole for the buckle 240, thereby being able to minimize the modification to the structure of the electric control box 100 and reduce the manufacturing cost.

[0053] Please continue to refer to Figure 5 In this embodiment, the number of the buckles 240 is two, and the positions of the two buckles 240 correspond to the positions of the two mounting holes 120. The two buckles 240 are respectively and correspondingly clamped and fixed in the two mounting holes 120. With such a setting, the connection reliability between the fireproof structure 200 and the electric control box 100 is ensured, so that the sealing plate 230 can be closely attached to the side plate 110, enhancing the sealing effect of the fireproof structure 200.

[0054] In other embodiments, the number of the buckles 240 provided on the sealing plate 230 can also be one. In this case, the buckle 240 is alternatively connected to one of the two mounting holes 120.

[0055] Please continue to refer to Figure 5 and Figure 6 In this embodiment, the sealing plate 230 may include a plate body 231 and a sealing rib 232 provided around the edge of the plate body 231. Among them, the sealing plate 230 is closely attached to the side plate 110 through the sealing rib 232.

[0056] After the fireproof structure 200 is installed on the electric control box 100, the sealing rib 232 contacts the side plate 110 prior to the plate body 231 and is closely attached to the side plate 110. With such a setting, the situation that the plate body 231 is not closely attached to the side plate 110 due to deformation tolerance can be avoided, thus ensuring the sealing effect of the sealing plate 230.

[0057] Please continue to refer to Figure 5 and Figure 6 In this embodiment, the buckle 240 may include a first clamping arm 241 and a second clamping arm 242 that are opposite and spaced apart. A first clamping protrusion 243 is provided on the surface of the first clamping arm 241 facing away from the second clamping arm 242, and a second clamping protrusion 244 is provided on the surface of the second clamping arm 242 facing away from the first clamping arm 241. The first clamping arm 241 and the second clamping arm 242 can pass through the mounting hole 120 and are clamped and fixed by the first clamping protrusion 243 and the second clamping protrusion 244.

[0058] When it is necessary to Figure 5 and Figure 6When the fireproof structure 200 shown is installed on the side plate 110, a force can be applied to the first clamping arm 241 and the second clamping arm 242, causing the first clamping arm 241 and the second clamping arm 242 to approach each other; then, the first clamping arm 241 and the second clamping arm 242 are pushed into the mounting hole 120; as the first clamping arm 241 and the second clamping arm 242 continuously move forward in the mounting hole 120, the first convex 243 and the second convex 244 also continuously move forward; when the first convex 243 and the second convex 244 completely protrude from the mounting hole 120, the first convex 243 and the second convex 244 will be clamped on the end face of the mounting hole 120, completing the installation of the fireproof structure 200.

[0059] When it is necessary to Figure 5 and Figure 6 remove the fireproof structure 200 shown from the side plate 110, the first clamping arm 241 and the second clamping arm 242 can be squeezed to make them approach each other, so that the mounting hole 120 releases the limit on the first convex 243 and the second convex 244, and then the first clamping arm 241 and the second clamping arm 242 can be taken out of the mounting hole 120 to complete the disassembly of the fireproof structure 200.

[0060] This structural form of the elastic buckle 240 facilitates the installation and disassembly of the fireproof structure 200 and can improve the installation and disassembly efficiency of the fireproof structure 200.

[0061] In this embodiment, the fireproof structure 200 combined with the electric control box 100 by a clamping connection can be a fireproof plastic part. Specifically, the material of this fireproof structure 200 can be ABS (Acrylonitrile Butadiene Styrene) plastic or EMC (Epoxy Molding Compound). The fireproof structure 200 in this material form has reliable fireproof performance.

[0062] In other embodiments, the fireproof structure 200 combined with the electric control box 100 by a clamping connection can also be a sheet metal part. Specifically, a convex bump can be stamped on the sheet metal part, and the clamping connection between the fireproof structure 200 and the electric control box 100 is realized by the insertion and fixation of the convex bump and the mounting hole 120. The fireproof structure 200 in this structural form has a lower cost.

[0063] Please continue to refer to Figure 2 and Figure 4 , in this embodiment, the fireproof structure 200 is located outside the electric control box 100. Such a setting facilitates the connection and disassembly operations of the fireproof structure 200 and the electric control box 100 by the staff.

[0064] In addition, this embodiment also provides an air conditioner, which includes the above-mentioned electronic control box assembly.

[0065] By providing the above-mentioned electronic control box assembly in the air conditioner, correspondingly, the air conditioner has all the advantages of the above-mentioned electronic control box assembly, which will not be elaborated one by one here.
