In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0061] The remote controller involved in the present application is mainly used to control the switches of household appliances such as air conditioners and water heaters or to adjust the target temperature. The remote controller is generally installed on the wall of a room or a balcony.

[0062] Since the remote controllers of air conditioners and water heaters installed in environments such as kitchens and bathrooms have a relatively high humidity in their use environments and there is a risk of contact with water, the requirements for the sealing performance of the remote controllers in such use environments are relatively high.

[0063] Specifically, the user can turn on or off the air conditioner or water heater by controlling the switch of the remote controller. Alternatively, the user can adjust the target temperature of the air conditioner through the touch screen or buttons, which is more convenient and has stronger practicability.

[0064] In view of the above technical problems, referring to Figures 1-7 , the present application provides a remote controller, which includes a first housing 100, a second housing 200, and a seal 300 disposed between the first housing 100 and the second housing 200.

[0065] The first housing 100 and the second housing 200 form the outer shell of the remote controller. The first housing 100 and the second housing 200 are detachably connected, and an accommodation cavity is formed between the first housing 100 and the second housing 200 for installing working components such as a main control board 600 and a power board 700.

[0066] In order to improve the sealing performance between the first housing 100 and the second housing 200, a seal 300 is provided at the connection position between the first housing 100 and the second housing 200.

[0067] The traditional seal 300 is an O-ring, which is clamped between the first housing 100 and the second housing 200 by a tight fit.

[0068] The O-ring may be deformed during the extrusion process, resulting in poor sealing.

[0069] To avoid the above problems, referring to Figure 8 , Figure 9 , the seal 300 designed in the present application is an integral closed ring, and the seal 300 at least includes a first seal portion 310 and a second seal portion 320.

[0070] The first seal portion 310 and the second seal portion 320 are spaced apart along the direction away from the accommodation cavity.

[0071] Referring to Figure 12 , Figure 13 , at least a first connection recess 120 and a second connection recess 130 are formed on the lower surface of the first housing 100.

[0072] The first connection recess 120 and the second connection recess 130 are respectively annular groove structures formed on the lower surface of the first housing 100.

[0073] The second connection recess 130 is located outside the first connection recess 120, that is, the first connection recess 120 and the second connection recess 130 are spaced apart along the direction away from the accommodation cavity.

[0074] Referring to Figure 10 ,Figure 11 On the second housing 200, a sealing surface 220 is formed. The seal 300 is adhered to the sealing surface 220 and is respectively connected into the first connecting recess 120 and the second connecting recess 130 to achieve at least double - layer sealing of the accommodation cavity.

[0075] Re - combination Figure 9 Moreover, for the convenience of installing the first sealing portion 310 and the second sealing portion 320, it is designed that the seal 300 further includes a gasket 330. The first sealing portion 310 and the second sealing portion 320 are arranged at intervals on the gasket 330, and the gasket 330 is fixed on the sealing surface 220.

[0076] The gasket 330 is annular, and the first sealing portion 310 and the second sealing portion 320 are formed on the upper surface of the gasket 330.

[0077] The lower surface of the gasket 330 is fixed on the sealing surface 220 by adhesion.

[0078] The first sealing portion 310, the second sealing portion 320, and the gasket 330 are of an integrally formed structure, and their material is waterproof silica gel. In the installed state, an interference fit is formed between the seal 300 and the first housing 100, which plays a role of at least double - layer sealing and improves the waterproof and anti - dust - smoke effects.

[0079] In some other embodiments, in addition to the first sealing portion 310 and the second sealing portion 320, at least a third sealing portion (not shown) can be provided on the upper surface of the gasket 330 to achieve multi - layer sealing between the first housing 100 and the second housing 200.

[0080] In some embodiments of the present application, in order to improve the accuracy of connection positioning between the first sealing portion 310 and the first connecting recess 120, and between the second sealing portion 320 and the second connecting recess 130, and improve the sealing effect, it is designed that the widths of the first sealing portion 310 and the second sealing portion 320 gradually decrease along the direction away from the gasket 330, and the widths of the first connecting recess 120 and the second connecting recess 130 gradually decrease as their depths increase.

[0081] In other words, the two sides of the first sealing portion 310 and the second sealing portion 320 are relatively inclined along the direction away from the gasket 330, and the tops of the first sealing portion 310 and the second sealing portion 320 are arc - shaped to be more conveniently and quickly positioned into the first connecting recess 120 and the second connecting recess 130.

[0082] The widths at the opening positions of the first connecting recess 120 and the second connecting recess 130 are the largest, and the first connecting recess 120 and the second connecting recess 130 are dimensionally tapered along the depth direction.

[0083] Then, during the connection process of the first housing 100 and the second housing 200, after the first sealing portion 310 and the second sealing portion 320 are inserted into the first connecting recess 120 and the second connecting recess 130, they are gradually tightly fitted and connected within the first connecting recess 120 and the second connecting recess 130.

[0084] The above connection form between the seal 300 and the first housing 100 effectively increases the contact area between the seal 300 and the first housing 100; the flue gas and water vapor are blocked outside the accommodation cavity under the action of the second sealing portion 320 and the first sealing portion 310, which is beneficial to improving the sealing effect of the accommodation cavity, improving the reliability of the operation of the main control board 600, the power supply board 700, etc. in the accommodation cavity, increasing the service life of the line controller, and reducing the maintenance cost.

[0085] Combined Figure 8 、 Figure 9 、 Figure 11 In some embodiments of the present application, in order to improve the connection accuracy between the seal 300 and the second housing 200 and facilitate the positioning of the seal 300 during installation, at least one first positioning portion 231 is provided on the sealing surface 220, and a second positioning portion 340 corresponding to the first positioning portion 231 is formed on the sealing gasket 330.

[0086] In some embodiments of the present application, the first positioning portion 231 is a positioning post structure formed on the sealing surface 220, and the second positioning portion 340 is a positioning hole formed on the sealing gasket 330. During installation, the first positioning portion 231 is inserted into the second positioning portion 340 at the corresponding position, which facilitates the connection and positioning of the seal 300.

[0087] In some other embodiments of the present application, an inner partition 230 extending upward is formed on the side of the sealing surface 220 close to the accommodation cavity, that is, the inner partition 230 is located inside the seal 300.

[0088] The inner partition 230 is annularly arranged along the circumference of the accommodation cavity.

[0089] The second positioning portion 340 is located inside the sealing gasket 330, that is, on the side close to the first sealing portion 310, and the first positioning portion 231 is formed outside the inner partition 230.

[0090] Specifically, in some embodiments of the present application, the first positioning portion 231 is a positioning convex portion formed outside the inner partition 230 and extending in a direction away from the inner partition 230, and the second positioning portion 340 is a positioning concave portion formed inside the sealing gasket 330.

[0091] During installation, the positioning concave portions on the seal 300 correspond to the positioning convex portions on the inner partition 230 one by one, which can also achieve the accurate positioning of the seal 300.

[0092] Refer again to Figure 11 In some embodiments of the present application, an installation surface 240 is further formed on the second housing 200. The installation surface 240 is located inside the inner partition 230, that is, the sealing surface 220 and the installation surface 240 are respectively located on both sides of the inner partition 230.

[0093] The first housing 100 and the second housing 200 are fixedly connected by means of fasteners.

[0094] Specifically, a through lower installation hole 241 is formed on the installation surface 240. A downward extending installation protrusion is formed on the lower surface of the first housing 100, and an upper installation hole 140 is formed on the installation protrusion. The fastener passes through the lower installation hole 241 from bottom to top and is connected in the corresponding upper installation hole 140 to realize the connection and fixation between the first housing 100 and the second housing 200.

[0095] Refer to Figure 14 FIG. 15, in some embodiments of the present application, an outer housing 400 is further provided outside the second housing 200. The outer housing 400 is used to fix the entire remote controller on the wall. In addition to further protecting the remote controller, it is also used to realize the connection and fixation between the remote controller and the wall.

[0096] The second housing 200 and the outer housing 400 are fixedly connected by means of snap connection to reduce the gaps generated during connection such as fasteners.

[0097] A snap connection portion 210 is formed on the outer wall of the second housing 200, and a snap buckle portion 410 is formed on the outer wall of the outer housing 400. The outer housing 400 is detachably connected to the snap connection portion 210 by means of snap connection.

[0098] An outer support surface 450 is formed on the circumferential side of the opening of the outer housing 400 for fitting on the second housing 200. The outer circumferential dimension of the outer support surface 450 is not greater than the outer circumferential dimension of the sealing surface 220.

[0099] A waterproof outer edge 110 extending towards the second housing 200 is formed on the circumferential side of the first housing 100. In the installed state, the waterproof outer edge 110 covers the outside of the sealing surface 220 and the outer support surface 450, playing a protective role to prevent the connection gaps between the first housing 100 and the second housing 200 and between the second housing 200 and the outer housing 400 from being exposed.

[0100] A through external connection hole 440 is provided on the outer support surface 450. During installation, first pass the fastening screw through the external connection hole 440 and fix it on the wall to realize the connection and fixation between the outer housing 400 and the wall surface, and then snap the assembled first housing 100 and second housing 200 onto the outer housing 400.

[0101] In some embodiments of the present application, limiting convex portions 420 are respectively formed on two opposite inner walls of the outer housing 400, and a limiting concave portion 250 adapted to the position of the limiting convex portion 420 is formed on the outer wall of the second housing 200 to facilitate positioning.

[0102] Combined Figure 2 、 Figure 12 and Figure 16 , in some embodiments of the present application, a main control board 600 is disposed in the accommodation cavity, and the main control board 600 is fixed on the lower surface of the first housing 100.

[0104] A connection convex portion 160 and a plug-in vertical portion 150 are formed on the first housing 100. The connection convex portion 160 is adapted to the position of the connection hole, and the plug-in vertical portion 150 is adapted to the position of the plug-in portion 610.

[0105] An insertion opening with an opening direction towards the connection convex portion 160 is formed on the plug-in vertical portion 150, and a threaded hole is formed on the connection convex portion 160.

[0106] During installation, one end of the main control board 600 is inserted into the plug-in vertical portion 150 through the plug-in portion 610, and then the connection hole is fixed on the connection convex portion 160 through a fastener to realize the connection and fixation of the main control board 600.

[0107] In some embodiments of the present application, reinforcing ribs 170 are further provided on the inner surface of the first housing 100. The reinforcing ribs 170 are arranged vertically and horizontally to improve the structural strength of the first housing 100 and reduce deformation.

[0108] Referring again to Figure 6 、 Figure 11 , in some embodiments of the present application, a power board 700 is further disposed in the accommodation cavity. The power board 700 is fixed in the second housing 200, and the power board 700 is fixed to the bottom of the second housing 200 through fasteners such as fastening screws.

[0110] A wiring stud 800 is further provided at the bottom of the second housing 200. One end of the wiring stud 800 extends into the accommodation cavity to be connected to the power board 700, and the other end extends to the outside of the second housing 200 for external connection of a power supply harness.

[0111] The outer side of the wiring stud 800 is configured to be connected to the power supply harness through a first crimping portion, and the inner side of the wiring stud 800 is configured to be detachably connected to the power board 700 through a second crimping portion.

[0112] The wiring stud 800 can play an intermediate conduction role in the connection between the power supply harness and the power supply board 700. The wiring stud 800 can avoid problems such as too large connection gaps, poor moisture-proof and dust-proof effects caused by the power supply harness directly passing through the second housing 200 and accessing the power supply board 700.

[0113] The outer housing 400 is also provided with a wire passing part for facilitating the connection of the power supply harness.

[0114] In some embodiments of the present application, a sealing foam 810 is further provided between the bottom of the second housing 200 and the outer housing 400 to improve the sealing effect at the bottom of the accommodation cavity.

In order to improve the installation accuracy of the sealing foam 810, an installation bottom groove 430 is provided at the bottom of the outer housing 400, and the size of the installation bottom groove 430 is adapted to the sealing foam 810.

[0116] The sealing foam 810 is connected between the second housing 200 and the outer housing 400 in a tight fit manner. The sealing foam 810 can seal the periphery of the wiring stud 800 to prevent flue gas, water vapor, etc. from entering the accommodation cavity from the bottom of the second housing 200, further improving the sealing effect of the accommodation cavity.

[0117] In some embodiments of the present application, a display part 500 is connected to the outer surface of the first housing 100, and the display part 500 is mainly a liquid crystal panel.

[0118] In order to improve the aesthetics and integrity of the surface of the remote controller and reduce the connection seams on the surface of the remote controller, the liquid crystal panel is fixed on the outer surface of the first housing 100 by pasting.

[0119] An installation groove part 180 is formed on the outer surface of the first housing 100, and the depth of the installation groove part 180 is adapted to the thickness of the liquid crystal panel.

[0129] The position of the first seal portion 310 corresponds to that of the first connecting recess 120, and the position of the second seal portion 320 corresponds to that of the second connecting recess 130.

[0130] A sealing surface 220 is formed on the second housing 200. The bottoms of the first seal portion 310 and the second seal portion 320 are fixed on the sealing surface 220 in a pasted manner.

[0131] In order to ensure the accurate installation position of the first seal portion 310 and the second seal portion 320 on the second housing 200, an annular first positioning groove and a second positioning groove are provided on the sealing surface 220.

[0132] The depths of the first positioning groove and the second positioning groove are less than those of the first seal portion 310 and the second seal portion 320, mainly playing an auxiliary positioning role for the first seal portion 310 and the second seal portion 320 to ensure the accurate positions of the first seal portion 310 and the second seal portion 320.

[0133] Method 2:

[0134] The seal 300 involved in this application is an enclosed ring as a whole, and at least includes a gasket 330, a first sealing portion 310, and a second sealing portion 320. The first sealing portion 310 and the second sealing portion 320 are spaced apart on the gasket 330 along the direction away from the accommodation cavity.

[0135] The gasket 330 is annular, the first sealing portion 310 and the second sealing portion 320 are formed on the upper surface of the gasket 330, and the lower surface of the gasket 330 is fixed on the sealing surface 220 by pasting.

[0136] The first sealing portion 310, the second sealing portion 320, and the gasket 330 are of an integrally formed structure, and their material is waterproof silica gel. In the installed state, an interference fit is formed between the seal 300 and the first housing 100, which plays a role of at least double-layer sealing and improves the waterproof and anti-smoke and dust effects.

[0137] In some other embodiments, in addition to the first sealing portion 310 and the second sealing portion 320, at least a third sealing portion may be provided on the upper surface of the gasket 330 to achieve multi-layer sealing between the first housing 100 and the second housing 200.

The second connecting concave portion 130 is located outside the first connecting concave portion 120, that is, the first connecting concave portion 120 and the second connecting concave portion 130 are spaced apart along the direction away from the accommodation cavity.

[0139] A sealing surface 220 is formed on the second housing 200. The seal 300 is pasted on the sealing surface 220 and is respectively connected into the first connecting concave portion 120 and the second connecting concave portion 130 to achieve at least double-layer sealing of the accommodation cavity.

[0140] Method 3:

[0141] The widths of the first sealing portion 310 and the second sealing portion 320 gradually decrease along the direction away from the gasket 330, and the widths of the first connecting concave portion 120 and the second connecting concave portion 130 gradually decrease as their depths increase.

[0142] In other words, the first sealing portion 310 and the second sealing portion 320 are tapered along the direction away from the gasket 330 to be more conveniently and quickly positioned into the first connecting concave portion 120 and the second connecting concave portion 130.

[0143] The widths at the opening positions of the first connecting concave portion 120 and the second connecting concave portion 130 are the largest, and the first connecting concave portion 120 and the second connecting concave portion 130 are tapered along the depth direction.

[0144] Then, during the connection process of the first housing 100 and the second housing 200, after the first sealing portion 310 and the second sealing portion 320 are inserted into the first connecting recess 120 and the second connecting recess 130, they are gradually tightly fitted and connected within the first connecting recess 120 and the second connecting recess 130.

[0145] The above three methods can be used separately for Method 1 and Method 2, or Method 1 or Method 2 can be combined with Method 3.
