Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an electric control box and an air conditioner. Background Art

[0002] At present, the controller of the household top-outlet outdoor unit is installed in the electric control box. The electric control box and the radiator for dissipating heat from the controller are usually arranged in the air duct, and the radiator is installed on the electric control box. After the radiator is assembled in place, there is inevitably an assembly gap between the radiator and the electric control box, and the sealing effect cannot be achieved. When the outdoor unit is running, water in the air duct will enter the controller through the assembly gap, which may easily cause a short circuit or burnout of the control board. Therefore, after the radiator is assembled in place, it is necessary to apply sealant around the radiator to ensure the sealing between the radiator and the electric control box during assembly.

[0003] However, it usually takes some time for the sealant to solidify, and the sealant still has a certain fluidity during the solidification process, and will flow into the interior of the electric control box through the assembly gap between the radiator and the electric control box, affecting the normal operation of the electrical components in the electric control box. Summary of the invention

[0004] The problem solved by the invention is how to prevent the sealant from flowing into the inside of the electric control box during the brush sealing process around the radiator.

[0005] In order to solve the above problem, the present invention provides an electric control box, on which a glue blocking groove is provided, and the glue blocking groove is located on the matching surface of the electric control box for mounting a radiator.

[0006] In this way, by setting a glue blocking groove on the mating surface of the electric control box for installing the radiator, the sealant will be blocked by the glue blocking groove when slowly penetrating into the assembly gap between the radiator and the electric control box, and will gather in the glue blocking groove and solidify in the glue blocking groove, thereby preventing the sealant from further flowing into the interior of the electric control box, thereby ensuring that the electrical components in the electric control box are not affected by the sealant and can be used normally.

[0007] Optionally, the electric control box is further provided with a heat dissipation port, and the heat dissipation port is located on the mating surface, and the glue blocking groove is arranged around the heat dissipation port.

[0008] In this way, it is ensured that the sealant that penetrates into the assembly gap between the radiator and the electric control box from all directions around the radiator can be blocked by the sealant blocking groove and gathered in the sealant blocking groove, thereby greatly improving the sealant blocking effect of the sealant blocking groove.

[0009] Optionally, a plurality of the glue blocking grooves are provided, and the plurality of the glue blocking grooves are sequentially arranged around the heat dissipation port.

[0010] In this way, by providing a plurality of glue blocking grooves, multiple lines of defense are formed to increase the capacity of the glue blocking grooves to accommodate the sealant, thereby ensuring that the glue blocking effect of the glue blocking grooves remains effective.

[0011] Optionally, the glue blocking groove includes a first glue blocking groove and / or a second glue blocking groove, the first glue blocking groove is arranged at the long side of the heat dissipation port and parallel to the long side of the heat dissipation port, and the second glue blocking groove is arranged at the short side of the heat dissipation port and parallel to the short side of the heat dissipation port.

[0012] In this way, by setting the first glue blocking groove along the length direction of the heat dissipation port and setting the second glue blocking groove along the width direction of the heat dissipation port, it is ensured that the glue blocking grooves are distributed in the length direction and / or width direction of the mating surface between the radiator and the electrical control box, thereby increasing the glue blocking range of the glue blocking grooves and improving the glue blocking effect.

[0013] Optionally, the electric control box includes an electric control box body and an annular rib arranged on the electric control box body, the matching surface is arranged on the electric control box body, and the annular rib is arranged around the matching surface.

[0014] In this way, when using the injection gun to spray glue, the muzzle of the injection gun can be used to spray glue along the sealing angle formed by the end surface of the annular rib away from the end connected to the electric control box body and the radiator, making glue spraying more convenient.

[0015] Optionally, when the heat sink is mounted on the mating surface, there is a distance between the inner wall of the annular rib and the heat sink.

[0016] In this way, a "track" is formed between the annular rib and the radiator, so that the gun head of the injection gun can spray glue along the "track", which is not only convenient to move but also accurate in positioning.

[0017] Optionally, a plurality of positioning ribs are provided on the electric control box body, and the plurality of positioning ribs are located in the area surrounded by the annular ribs and are arranged around the matching surface.

[0018] In this way, by setting a plurality of positioning ribs on the electric control box body, the radiator can be pre-positioned for installation, so as to facilitate the installation of the radiator; at the same time, the radiator can be limited after being installed in place to prevent the radiator from moving along the length direction or width direction of the heat dissipation port on the mating surface of the electric control box.

[0019] Optionally, one end of the positioning rib is connected to the inner wall of the annular rib, and the other end is used to abut against the heat sink.

[0020] In this way, one end of the positioning rib is connected to the annular rib, so that the positioning rib can not only achieve pre-positioning but also increase the strength of the annular rib and prevent the annular rib from deformation.

[0021] Optionally, a guide surface inclined toward the radiator is provided on the positioning rib, and a distance from the guide surface to the mating surface gradually decreases along a direction from an end of the positioning rib away from the radiator to an end close to the radiator.

[0022] In this way, the guide surface is arranged on the positioning rib in an inclined direction from the back to the front, so as to guide the radiator to be smoothly installed when assembling the radiator, thereby improving the assembly efficiency of the radiator.

[0023] Optionally, the annular rib and the electric control box body together form a mounting groove, and a limit buckle and a mounting hole are provided in the mounting groove, the limit buckle is used to clamp with one end of the radiator, and the mounting hole is used to be detachably connected with the other end of the radiator through a fastener.

[0024] In this way, when installing the radiator, first insert the radiator into the installation slot with one end of the limit buckle so that one end of the radiator is engaged with the limit buckle, and then install the radiator into the installation slot with the other end of the installation hole, and finally screw the fasteners on the installation hole to fix the radiator in the installation slot. The structure is simple and the installation is convenient.

[0025] Optionally, the mounting hole is arranged on the bottom of the mounting slot, and the limiting buckle is arranged on the slot wall at one end of the mounting slot away from the mounting hole.

[0026] In this way, by arranging the limiting buckle on the groove wall at one end of the mounting groove away from the mounting hole, the base area of ​​the radiator can be further increased, so as to add heat sinks on the base of the radiator to improve the heat dissipation effect.

[0027] Optionally, a limiting rib is further provided in the installation groove, and two ends of the limiting rib are respectively connected to two oppositely arranged inner walls of the annular rib.

[0028] In this way, the two oppositely disposed inner walls of the annular rib are connected by the limiting rib, thereby further enhancing the structural strength of the annular rib.

[0029] Optionally, the limiting buckle is arranged on the limiting rib, and when the heat sink is installed in the installation groove, one end of the heat sink facing the limiting buckle abuts against the limiting rib.

DETAILED DESCRIPTION

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", "high", "low", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and in the coordinate system XYZ provided herein, the positive direction of the X-axis represents the front, the reverse direction of the X-axis represents the back, the positive direction of the Y-axis represents the right, the reverse direction of the Y-axis represents the left, the positive direction of the Z-axis represents the top, and the reverse direction of the Z-axis represents the bottom; these are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0044] Combination Figure 1 and Figure 2 As shown, this embodiment provides an electric control box 2, on which a glue blocking groove 24 is provided, and the glue blocking groove 24 is located on the matching surface of the electric control box for mounting the heat sink 1.

[0045] In the top-outlet outdoor unit, since the radiator 1 is usually installed on the rear side of the electric control box 2, the mating surface of the electric control box for mounting the radiator 1 is set on the rear side of the electric control box 2 (that is, the electric control box 2 is located at the rear side of the electric control box 2). Figure 1 The side opposite to the X-axis in the middle). After the radiator 1 is installed on the electric control box 2, the electric control box 2 and the radiator 1 are fitted with each other, and the fitting part located on the electric control box 2 is the matching surface on the electric control box 2 for installing the radiator 1. That is to say, after the radiator 1 is installed on the electric control box 2, the radiator 1 blocks the glue blocking groove 24 to prevent the sealant from directly flowing into the glue blocking groove 24 when brushing the glue.

[0046] In order to ensure the sealing between the radiator 1 and the electric control box 2, after the radiator 1 is installed on the electric control box 2, it is necessary to apply glue around the connection between the radiator 1 and the electric control box 2. However, since the sealant still has a certain fluidity before it is completely solidified, it is easy to flow into the inside of the electric control box 2 from the assembly gap between the radiator 1 and the electric control box 2. In this embodiment, by providing a glue blocking groove 24 on the electric control box 2, and providing the glue blocking groove 24 on the mating surface of the electric control box 2 for installing the radiator 1, the sealant will be blocked by the glue blocking groove 24 during the process of slowly penetrating into the assembly gap between the radiator 1 and the electric control box 2, and will gather in the glue blocking groove 24 and solidify in the glue blocking groove 24, thereby preventing the sealant from further flowing into the inside of the electric control box 2, ensuring that the electrical components in the electric control box 2 are not affected by the sealant and can be used normally.

[0047] Optionally, combined Figure 1 As shown, the electric control box 2 is further provided with a heat dissipation port 25 , and the heat dissipation port 25 is located on the mating surface of the electric control box 2 , and the glue blocking groove 24 is arranged around the heat dissipation port 25 .

[0048] In order to ensure the heat dissipation effect of the electric control box 2, a heat dissipation port 25 is usually provided on the electric control box 2, and the radiator 1 is installed at the heat dissipation port 25. Since the radiator 1 is installed on the mating surface of the electric control box 2, the heat dissipation port 25 is opened on the mating surface of the electric control box 2. In this embodiment, the glue blocking groove 24 is provided around the heat dissipation port 25, which means that the glue blocking groove 24 can be a ring-shaped groove structure or a multi-segment groove structure, and the multi-segment groove structure is distributed around the heat dissipation port 25. In this way, it is ensured that the sealant that penetrates into the assembly gap between the radiator 1 and the electric control box 2 from all directions around the radiator 1 can be blocked by the glue blocking groove 24 and gathered in the glue blocking groove 24, thereby enhancing the glue blocking effect of the glue blocking groove 24 to a greater extent.

[0049] Optionally, combined Figure 5 and Figure 6 As shown, the width W and the depth h of the glue blocking groove 24 are set to be about 1 mm, and the distance between the glue blocking groove 24 and the edge of the heat sink 1 is between 2 mm and 3 mm.

[0050] If the width W and depth h of the glue blocking groove 24 are set too large, the sealant that leaks into the space between the radiator 1 and the electric control box 2 cannot fill the sealant blocking groove 24, so that after the sealant solidifies, there is still a gap between the radiator 1 and the electric control box 2; and if the distance between the sealant blocking groove 24 and the edge of the radiator 1 is set too large, it is easy to cause the sealant to solidify on the mating surface before leaking into the sealant blocking groove 24, so that there is still a gap between the radiator 1 and the electric control box 2 at the sealant blocking groove 24. Therefore, in this embodiment, the width W and depth h of the glue blocking groove 24 are set to about 1 mm to further ensure the sealing between the radiator 1 and the electric control box 2 during the glue brushing process.

[0051] Optionally, combined Figure 1 and Figure 3 As shown, a plurality of the glue blocking grooves 24 are provided, and the plurality of glue blocking grooves 24 are sequentially arranged around the heat dissipation opening 25 .

[0052] A plurality of glue blocking grooves 24 are connected in sequence around the heat dissipation port 25 to form an annular structure. The plurality of glue blocking grooves 24 may be interconnected or disconnected. When too much sealant is applied, the amount of sealant that penetrates into the assembly gap between the radiator 1 and the electric control box 2 will also increase, and the capacity of a glue blocking groove 24 to accommodate sealant is limited. In this embodiment, by providing a plurality of glue blocking grooves 24, multiple lines of defense are formed to increase the capacity of the glue blocking groove 24 to accommodate sealant, thereby ensuring that the glue blocking effect of the glue blocking groove 24 remains effective.

[0053] Optionally, combined Figure 1 As shown, the glue blocking groove 24 includes a first glue blocking groove 241 and / or a second glue blocking groove 242. The first glue blocking groove 241 is arranged at the long side of the heat dissipation port 25 and parallel to the long side of the heat dissipation port 25, and the second glue blocking groove 242 is arranged at the short side of the heat dissipation port 25 and parallel to the short side of the heat dissipation port 25.

[0054] The heat dissipation port 25 is generally rectangular, having a long side and a short side, with the direction parallel to the long side of the rectangular heat dissipation port 25 being the length direction of the heat dissipation port 25, and the direction parallel to the short side of the heat dissipation port 25 being the width direction of the heat dissipation port 25. In this embodiment, the glue blocking groove 24 may be composed of a multi-section groove structure, that is, the glue blocking groove 24 includes a first glue blocking groove 241 and a second glue blocking groove 242, or may only include the first glue blocking groove 241 or the second glue blocking groove 242, wherein the first glue blocking groove 241 is located at the long side of the heat dissipation port 25 and extends along the length direction of the heat dissipation port 25, and the second glue blocking groove 242 is located at the short side of the heat dissipation port 25 and extends along the width direction of the heat dissipation port 25.

[0055] In this embodiment, by setting the first glue blocking groove 241 along the length direction of the heat dissipation port 25 and setting the second glue blocking groove 242 along the width direction of the heat dissipation port 25, it is ensured that the glue blocking groove 24 is distributed in the length direction and / or width direction of the mating surface between the radiator 1 and the electrical control box, thereby increasing the glue blocking range of the glue blocking groove 24 and improving the glue blocking effect.

[0056] Optionally, combined Figure 1 and Figure 3 As shown, a plurality of first glue blocking grooves 241 are provided, and the plurality of first glue blocking grooves 241 are interconnected, and / or a plurality of second glue blocking grooves 242 are provided, and the plurality of second glue blocking grooves 242 are interconnected.

[0057] The rectangular heat dissipation port 25 has two long sides and two short sides. For the first glue blocking groove 241 at one of the long sides of the heat dissipation port 25, the interconnection of multiple first glue blocking grooves 241 means that the ends or other parts of the multiple first glue blocking grooves 241 are interconnected; and for the multiple first glue blocking grooves 241 at the two long sides of the heat dissipation port 25, the interconnection of multiple first glue blocking grooves 241 means that the first glue blocking grooves 241 at the two long sides of the heat dissipation port 25 are all connected with the multiple second glue blocking grooves 242 at the short sides of the heat dissipation port 25, so that the first glue blocking grooves 241 at the two long sides of the heat dissipation port 25 are interconnected. Similarly, the situation that the multiple second glue blocking grooves 242 are interconnected is the same as the situation that the multiple first glue blocking grooves 241 are interconnected, and will not be repeated here.

[0058] When too much sealant is applied, more sealant will penetrate into the assembly gap between the radiator 1 and the electric control box 2, while the capacity of the first sealant blocking groove 241 and the second sealant blocking groove 242 to hold the sealant is limited. In this embodiment, multiple first sealant blocking grooves 241 and / or multiple second sealant blocking grooves 242 are provided to form multiple lines of defense, so as to further increase the capacity of the sealant blocking groove 24 to hold the sealant, and further ensure that the sealant blocking function of the sealant blocking groove 24 is maintained effectively.

[0059] Optionally, combined Figure 1As shown, the electric control box 2 includes an electric control box body 21 and an annular rib 22 arranged on the electric control box body 21. The mating surface of the electric control box 2 is arranged on the electric control box body 21, and the annular rib 22 is arranged around the mating surface.

[0060] The sealant is usually sprayed around the connection between the radiator 1 and the electric control box 2 by an injection gun. In order to facilitate the injection gun to spray the sealant, in this embodiment, a circle of annular ribs 22 are provided on the mating surface of the electric control box body 21, and the annular ribs 22 are provided protruding from the rear end surface of the electric control box body 21. In this way, when the injection gun is used to spray the sealant, the muzzle of the injection gun can be sprayed along the sealing angle formed by the end surface of the annular ribs 22 away from the end connected to the electric control box body 21 and the radiator 1, making the spraying of the sealant more convenient.

[0061] Optionally, combined Figure 1 As shown, when the heat sink 1 is mounted on the mating surface, there is a distance between the inner wall of the annular rib 22 and the heat sink 1 .

[0062] When the radiator 1 is installed on the mating surface, there is a distance between the inner wall of the annular rib 22 and the radiator 1, wherein the inner wall of the annular rib 22 refers to the side located on the inner circle of the annular rib 22, which is also the side of the annular rib 22 facing the radiator 1; this forms a "track" between the annular rib 22 and the radiator 1, so that the gun head of the injection gun can spray glue along the "track", which is not only convenient to move but also accurate in positioning.

[0063] Optionally, the distance between the inner wall of the annular rib 22 and the radiator 1 can be appropriately adjusted according to the size of the gun tip of the injection gun. Generally, the distance is set to be 2mm-3mm larger than the size of the gun tip of the injection gun. For example, the distance can be set to about 5mm, which is not specifically limited in this embodiment.

[0064] Optionally, the height of the annular rib 22 protruding from the rear end surface of the electric control box body 21 is between 8 mm and 12 mm, and 10 mm is generally preferred. In this way, on the one hand, it can be prevented that the protruding height of the annular rib 22 is set too large, resulting in the "track" formed between the annular rib 22 and the radiator 1 being too deep, so that the gun head of the injection gun cannot be inserted into the "track" for glue spraying, and on the other hand, it can also be prevented that the protruding height of the annular rib 22 is set too small to form a "track" that is convenient for glue spraying.

[0065] Optionally, combined Figure 3 and Figure 4 As shown, a plurality of positioning ribs 29 are provided on the electric control box body 21 . The plurality of positioning ribs 29 are located in the area surrounded by the annular ribs 22 and are arranged around the mating surface of the electric control box 2 .

[0066] In this embodiment, a plurality of positioning ribs 29 are provided on the electric control box body 21 to pre-position the radiator 1 for installation, so as to facilitate the installation of the radiator 1; at the same time, the radiator 1 can be limited after being installed in place to prevent the radiator 1 from moving along the length direction or width direction of the heat dissipation port 25 on the mating surface of the electric control box 2.

[0067] Optionally, combined Figure 3 and Figure 4 As shown, one end of the positioning rib 29 is integrally formed with the inner wall of the annular rib 22 , and the other end is used to abut against the heat sink 1 .

[0068] In this embodiment, one end of the positioning rib 29 is connected to the annular rib 22, so that the positioning rib 29 can not only achieve pre-positioning but also increase the strength of the annular rib 22 to prevent the annular rib 22 from deformation.

[0069] Optionally, there is a gap between the end of the positioning rib 29 facing the radiator 1 and the radiator 1, and the gap is between 0.2mm-0.4mm. If the gap between the end of the positioning rib 29 facing the radiator 1 and the radiator 1 is too small, it will cause difficulty in installing the radiator 1. If the gap between the end of the positioning rib 29 facing the radiator 1 and the radiator 1 is too large, the positioning rib 29 cannot play a limiting role. Therefore, in this embodiment, the gap between the end of the positioning rib 29 facing the radiator 1 and the radiator 1 is set to be between 0.2mm-0.4mm, so as to ensure that the positioning rib 29 can facilitate the installation of the radiator 1 while having a limiting effect.

[0070] Optionally, a guide surface inclined toward the radiator 1 is provided on the positioning rib 29, and the matching distance between the guide surface and the electric control box 2 gradually decreases from the end of the positioning rib 29 away from the radiator 1 to the end close to the radiator 1.

[0071] The distance from the guide surface to the mating surface gradually decreases from the end of the positioning rib 29 away from the radiator 1 to the end close to the radiator 1, indicating that the distance from the guide surface to the mating surface gradually decreases along the installation direction of the radiator 1. Figure 2 The guide surface 29 is installed on the mating surface of the electric control box 2 (with the X-axis in the reverse direction facing the X-axis positive direction), so the installation direction of the radiator 1 refers to the direction from back to front. In other words, the distance from the guide surface to the mating surface gradually decreases from back to front, indicating that the guide surface is inclined from back to front on the positioning rib 29, so as to guide the radiator 1 to be smoothly installed on the mating surface of the electric control box 2 when assembling the radiator 1, thereby improving the assembly efficiency of the radiator 1.

[0072] Optionally, combined Figure 3 , Figure 4 and Figure 7As shown, the annular rib 22 and the electric control box body 21 together form a mounting groove 23, and a limit buckle 26 and a mounting hole 27 are provided in the mounting groove 23. The limit buckle 26 is used to be clamped with one end of the radiator 1, and the mounting hole 27 is used to be detachably connected to the other end of the radiator 1 through a fastener.

[0073] In this embodiment, the notch of the installation groove 23 formed by the annular rib 22 and the electric control box body 21 faces backward (ie, toward Figure 1 In this way, when installing the radiator 1, first insert the radiator 1 into the installation groove 23 with one end of the limit buckle 26, so that one end of the radiator 1 is engaged with the limit buckle 26, and then install the radiator 1 into the installation groove 23 with the other end of the installation hole 27, and finally screw the fastener on the installation hole 27 to fix the radiator 1 in the installation groove 23. The structure is simple and the installation is convenient.

[0074] Optionally, combined Figure 3 , Figure 4 and Figure 7 As shown, the mounting hole 27 is arranged on the bottom of the mounting slot 23 , and the limiting buckle 26 is arranged on the slot wall of the mounting slot 23 at one end away from the mounting hole 27 .

[0075] In this embodiment, the mounting hole 27 is arranged on the bottom of the mounting groove 23, and the limiting buckle 26 can be arranged on the groove wall of the mounting groove 23 at one end away from the mounting hole 27, or can be arranged on the groove bottom of the mounting groove 23 at one end away from the mounting hole 27; in this embodiment, the limiting buckle 26 is preferably arranged on the groove wall of the mounting groove 23 at one end away from the mounting hole 27, and the limiting buckle 26 and the mounting hole 27 are respectively close to two oppositely arranged groove walls of the mounting groove 23, for example Figure 3 In the embodiment, the mounting groove 23 is in the left and right direction (i.e. Figure 3 Y-axis direction) and up and down direction (i.e. Figure 3 The mounting holes 27 and the mounting holes 28 are respectively arranged close to the groove walls of the mounting groove 23 in the Y-axis direction. Specifically, the positioning buckle 26 is arranged close to the right groove wall of the mounting groove 23, and the mounting hole 27 is arranged close to the left groove wall of the mounting groove 23. Figure 3 In addition to the arrangement in the embodiment, the limit buckle 26 and the mounting hole 27 can also be respectively arranged close to the groove wall of the mounting groove 23 in the Z-axis direction, for example, the limit buckle 26 is arranged close to the upper groove wall of the mounting groove 23, and the mounting hole 27 is arranged close to the lower groove wall of the mounting groove 23, which is not specifically limited in this embodiment. In this way, by arranging the limit buckle 26 on the groove wall of the mounting groove 23 away from the mounting hole 27, the base area of ​​the radiator 1 can be further increased, so as to add a heat sink on the base of the radiator 1 to improve the heat dissipation effect.

[0076] Optionally, combined Figure 4 and Figure 7 As shown, a limiting rib 28 is further provided in the mounting groove 23, and the two ends of the limiting rib 28 are respectively connected to the two opposite inner walls of the annular rib 22. In this way, the two opposite inner walls of the annular rib 22 are connected by the limiting rib 28, thereby enhancing the structural strength of the annular rib 22.

[0077] Optionally, combined Figure 4 and Figure 7 As shown, the limiting buckle 26 is arranged on the limiting rib 28 ; when the radiator 1 is installed in the installation groove 23 , one end of the radiator 1 facing the limiting buckle 26 abuts against the limiting rib 28 .

[0078] In this embodiment, the limiting buckle 26 is arranged on the limiting rib 28, so that after the radiator 1 is engaged with the limiting buckle 26, the end of the radiator 1 facing the limiting buckle 26 can abut against the limiting rib 28 at the position of the limiting buckle 26, thereby limiting the radiator 1 to ensure that the installation of the radiator 1 is stable and reliable.

[0079] The present invention further provides an air conditioner to solve the problem of how to prevent the sealant from flowing into the interior of the electric control box during the brush sealing process around the radiator. The air conditioner includes any of the above-mentioned electric control boxes.

[0080] The air conditioner in this embodiment is provided with a glue blocking groove 24 on the mating surface of the electric control box 2 for mounting the radiator 1; thus, when the sealant slowly penetrates into the assembly gap between the radiator 1 and the electric control box 2, it will be blocked by the glue blocking groove 24, gathered in the glue blocking groove 24, and solidified in the glue blocking groove 24, thereby preventing the sealant from further flowing into the interior of the electric control box 2, ensuring that the electrical components in the electric control box 2 are not affected by the sealant and can be used normally.

[0081] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
