The present invention relates to a remote control, and more particularly, to have a waterproof function in a state in which the power supply unit and the board unit are separated from each other, so that the present invention can be used without degrading the functionality of the remote control in a kitchen or a bathroom.

In general, in home appliances, the use of a remote controller is increasing so that the operation of electronic products can be controlled from a long distance for consumer convenience.

Recently, the remote control is also required to waterproof in accordance with the trend of increasing the frequency of use of electronic products in places with high humidity and moisture, such as bathrooms and kitchens.

A typical remote controller includes a casing, a substrate portion for controlling the operation and on / off of electronic products therein, a button portion for providing a function to the substrate portion, and a power supply for operation of the substrate portion through the button portion. It is largely comprised of a power supply section and a cover which is covered to protect them in a housed state.

The conventional coupling method of the casing and the cover of the remote control for a conventional electronic product is configured to allow the hooking groove to be dug on one side, and the hook is hooked to a corresponding position.

The conventional remote control is configured as described above simply because the hook hook is engaged by the engaging portion at the engaging position of the casing and the cover, but the purpose of preventing the cover from being separated can be achieved. Likewise, it did not have the waterproof and moisture resistant functions required in places with high contact with moisture and water.

Therefore, when using the remote control without the waterproof function for the operation of the electric equipment installed in the kitchen or bathroom, moisture and moisture flows into the remote control, and various parts including the circuit board, the power supply housed with the battery, and various other terminals are easily damaged. There was a problem such as not functioning with the remote control.                         

In addition, it may be considered to have a complicated structure sealing treatment at the coupling portion of the casing and the cover, but not only the cost is greatly increased, but also the waterproof ability is greatly reduced when the cover is frequently disassembled for battery replacement or repair. There was a problem such as being.

On the other hand, the recently used remote control is made of a structure that mostly covers the opening part with the main cover in a state in which all the mechanisms, circuits and battery power are accommodated therein, and covers only the position of the power supply part with a separate cover. .

In addition, since the power supply cover needs to open and close the cover relatively frequently, it is difficult to apply a sealing structure for waterproofing the hook hook to be caught in the hook hole as in the prior art.

Therefore, the conventional remote control having no sealing structure does not have a big problem when mainly used only in a room temperature and a dry place, but when a lot of moisture is generated, especially when the temperature changes frequently due to the use of a cooker or hot water, moisture may flow into the body. In addition, inadvertent flooding caused the circuit to be damaged, causing irreparable failure.

On the other hand, the conventional remote control structures known in Japanese Patent Application Laid-Open No. 2822601 and Japanese Patent Application Laid-open No. Hei 7-132134 are disposed at appropriate positions in a wide space in which a power supply unit consisting of a substrate and a battery forming a circuit is united.

Therefore, the variety and convenience of the arrangement of parts, but weak to external factors such as impact or pressure changes.                         

That is, according to the rectangular case structure, which has a long length in one direction, the supporting force for supporting the central part is very weak, so if the inadvertent drop or a sudden pressure change factor occurs, the creek is generated in the weak central part or severely damaged. There was a problem such as throwing away.

An object of the present invention is to provide a remote control that can be opened and closed only the necessary portion by providing a cover, each of the power supply and the board portion is excellent waterproof.

Another object of the present invention is to provide a remote control to improve the reliability and ease of use of the product.

The object of the present invention is a casing (100) having a substrate receiving portion 101 and the power receiving portion 102 is opened toward the rear;

A substrate part cover 200 which covers the substrate receiving part 101 of the casing 100;

A power supply cover 300 which covers the power receiving portion 102 of the casing;

A partition wall 600 formed across the casing 100 so as to distinguish the substrate receiving portion 101 and the power receiving portion 102;

It is achieved by consisting of a packing member 400 provided around the substrate cover 200 and the power supply cover 300.

Therefore, the substrate and the power supply cover can be detachably installed, but have an excellent waterproof function to protect the liquid crystal panel or other various electronic circuits and sealing parts from being damaged.

In addition, it is possible to further improve the merchandise and reliability of the product by protecting the various circuits and structures accommodated in the substrate accommodating portion 101 and the power accommodating portion 102 even if the partition wall 600 is excellent in strength and withstand pressure changes. .

The remote control of the present invention is mainly suitable for remote control of home appliances and boilers installed in kitchens or bathrooms, and is a device that prevents damage to circuits and various parts by enabling safe and ventilation under conditions of rapid pressure change as well as waterproofing. You will be prepared.

The casing 100 has a hollow housing type, and has a power receiving portion 102 and a partition 600 interposed therebetween with a power receiving portion 102 for accommodating a battery for power therein and a substrate receiving portion 101 at one side thereof. do.

Then, the substrate receiving portion 101 of the casing 100 is covered with the substrate cover 200, and the power receiving portion 102 is covered with a separate power supply cover 300 in a separate state.

A packing member 400 is installed around the substrate cover 200 and the power supply cover 300 for waterproof and airtightness.

The packing member 400 is fitted to the substrate cover 200 and the power supply cover 300 so as to correspond to the size of the substrate receiving portion 101 and the power receiving portion 102. It is installed in the portions 210 and 310.

The packing member 400 is a rubber material having good elasticity and airtightness, and its cross section is “O” type so as to be stepped on the substrate cover 200 and the power supply cover 300 having a substantially quadrangular shape as shown in FIG. 1. The grooves 211 and 311 of the formed fitting portions 210 and 310 are mounted.

Accordingly, the substrate cover 200 and the power cover (see FIG. 3, 7 and 9 in enlarged cross-sectional view) to seal the board receiving portion 101 and the power receiving portion 102 of the casing 100. The packing member 400 completely seals the gap in the state in which 300 is covered, thereby keeping the inside sealed from dust or moisture outside.

As described above, the partition wall 600 that separates the substrate receiving portion 101 and the power receiving portion 102 of the casing 100 is integrally formed in the casing 100 so as to be split across the casing 100 so as to form an inner wall of the casing 100. The joint portion connected to the to form a round portion 610 during the injection process to reinforce the strength.

The round part 610 becomes vulnerable when an edge of a substantially right angle is formed at the joint portion in the process of integrally molding the partition 600 with the casing 100.

Therefore, as shown in the drawing, the rounded portion 610 is formed in the joint portion to reinforce the strength, so that various circuits and structures accommodated in the substrate accommodating portion 101 and the power accommodating portion 102 are applied. Will be protected.

In addition, the partition 600 has a connection passage 620 for connecting a power source of a battery for power supply mounted on the power receiving unit 102 and a substrate, a display panel, and the like, which are located in the board receiving unit 101, with a wire or lead cable. Will be penetrated.

The power accommodating part 102 is provided with a power terminal 103 capable of conducting electricity in a metal material for electrical wiring of a battery.

The substrate receiving unit 101 is provided with a viewing window 104 so that the display panel can be observed from the outside, and the screw holes 105 are fastened to the casing 100 while the substrate unit cover 200 is covered. It is drilled in several places.

In addition, the substrate part cover 200 penetrates the through holes 201 to positions corresponding to the screw holes 105 so that the screws 250 may penetrate and be fastened to the screw holes 105. 250 is preferably fastened by inserting the water washer 251.

The waterproof washer 251 is installed to prevent the possibility of minute gaps generated at the fastening position of the bis 250 for complete internal waterproofing, the material is made of rubber or silicon material or more excellent, but the substrate cover ( The similarity of material to that of 200 is used with washers made of Teflon material.

Here, in addition to the method of screwing the vis as a fastening means of the casing 100 and the substrate cover 200, it is clear that both of the fixing method to allow the elastic hook to be caught in the locking hole.

On the other hand, the casing 100 is molded to have a relatively thick thickness as a whole to improve the impact resistance, in particular the bottom of the long hole-shaped grooves 150 as shown in Figs.

These grooves 150 absorb the shock when the impact is applied by dropping the remote control during use, and the material is saved.

On the other hand, the locking means 500 for detachably fixing the power supply cover 300 to the casing 100 is provided.

The locking means 500 requires a function of maintaining both waterproof airtightness and robustness while being relatively easy and quick to operate.

In the present invention, the locking means 500 is configured to operate the sealing or opening of the power supply cover 300 more quickly and quickly by one-touch operation.

That is, the locking means 500 protrudes the boss 510 to the power receiving portion 102 of the casing 100 as shown in FIGS. 3 to 6, and has a shaft hole 511 at the center of the boss 510. ) And the entrance hole 512 to both sides thereof.

In addition, the cam surface 513 is formed to be inclined immediately inside the entrance hole 512.

In addition, the power supply cover 300 in the assembled state to the position corresponding to the shaft hole 511, the rotating plate 520, and the shaft 530 integrated with the rotating plate 520 through the shaft assembly hole 532 Install in a rotatable state.

The shaft 530 has a snap ring 540 installed on the inner surface of the power supply cover 300 to prevent it from being separated from the assembled state in the power supply cover 300, and may come and go through the access hole 512. The pin 531 is installed through the shaft 530 end side so that it can be installed.

Accordingly, when the shaft 530 and the pin 531 are positioned in the shaft hole 511 and the entrance hole 512 in a state in which the power supply cover 300 is positioned in the casing 100 and then pushed into the shaft 100, the shaft ( The 530 and the pin 531 are further entered to move the pin 531 to a position in contact with the cam surface 513 located inside the entrance hole 512.

In this state, when the user rotates the rotating plate 520 exposed to the outside of the power supply cover 300 by about 90 °, the pin 531 is moved along the cam surface 513 to further closely contact the power supply cover 300. It will pull in the direction so that it can be completely fixed.

At this time, the boss 510 is rotated only in a position where the rotation range of the pin 531 is optimal, that is, the power supply cover 300 is completely pulled, and the intermittent jaw 514 enters and exits in consideration of a position where no further rotation is necessary. It is provided in the hole 512 in a substantially perpendicular position.

Therefore, the casing 100 and the power supply cover 300 are to maintain their intermittent force in the fully locked state.

Then, when the power supply cover 300 for the maintenance or replacement of the battery or other components in the locked state, the rotating plate 520 and the shaft 530 integral thereto are reversely rotated.

Then, the pin 531 is guided in the reverse direction along the cam surface 513 and when a small force is applied at the position of the entrance hole 512, the pin 531 and the shaft 530 together with the power supply cover 300 are disassembled and locked. You can release the state.

At this time, as a means for the user to simply rotate the rotating plate 520 is installed in the rotating plate 520 ring handle 521 having a semi-circular ring shape to be folded.

The ring handle 521 is accommodated in the spare part 320 which is dug inwardly in the power supply cover 300 when not in use, and is lifted from the rotating plate 520 only when in use to be held by the user by hand to rotate the shaft 530. The rotation operation of the pin 531 is made possible.

Also, as shown in FIGS. 4A and 4B, the operation groove 523 for protruding the straight gripping protrusion 522 to be held by the rotating plate 520 by hand or by inserting and rotating the screw by using a screwdriver or a coin is formed to be drilled. The configuration may be applied.

Therefore, according to the structure of the locking means 500, it is possible to maximize the waterproof performance by improving the adhesion by further pulling at the same time to prevent the separation of the power supply cover 300.

Here, the case in which the structure of the locking means 500 is applied to the power supply cover 300 has been shown and described, but it is apparent that the same structure can be applied to the substrate cover 200.

In addition, the front panel of the casing 100, the front panel for preventing the space punched for the molding of the shaft hole 511 and the entrance groove 512 and the cam surface 513, as well as a variety of functional part markings and trademarks, etc. 130).

The front panel 130 is more strongly bonded to the casing 100 to have a waterproof function.

And, any one of the substrate cover 200 or the power supply cover 300 is provided with a static pressure maintaining means 700 to block the pressure change in the casing 100 due to a sudden pressure difference.

That is, as shown in FIGS. 6 and 7, the positive pressure holding means 700 forms a pocket 720 in a state in which indoors and outdoors can communicate with each other, and changes the state according to the pressure change in the pocket 720. By installing the diaphragm 710 to balance the balance.

The diaphragm 710 is a rubber material having good flexibility and toughness in a thin disk state, and is capable of maintaining a constant pressure state while being instantaneously deformed against sudden pressure changes on both sides.

In the case of the remote control, when it is submerged in a place different from the internal and external temperature, a sudden pressure deviation occurs, and even if the remote control is well waterproof, the deformation occurs in the sealing part and the coupling part to achieve the pressure balance naturally.

At this time, the diaphragm 710 is instantaneously deformed with respect to the pressure change according to the pressure deviation, and the pressure inside the remote controller can always maintain a constant state, that is, a constant pressure state, so that the casing 100, the power supply cover 300, and the substrate cover ( It is possible to prevent the airtightness deterioration that may be caused by the pressure difference to the various sealing portions and various parts of the coupling portion of 200).

The pocket 720 for installing the diaphragm 710 forms a circular ring-shaped support 730 inside the substrate cover 200, and the cap 740 in a state where the diaphragm 710 is positioned. By coupling to the support 730 in the form of interference fit to form a pocket 720 for operating the diaphragm 710 between the cap 740 and the inner wall of the substrate cover 200.

In addition, the cap 740 drills several communication holes 741 and the communication part 270 is also drilled in the substrate cover 200 so that the diaphragm 710 positioned therebetween can act on both sides of the pressure. will be.

Here, the case in which the structure of the positive pressure maintaining means 700 is applied to the substrate cover 200 is illustrated and described, but it is apparent that the same structure can also be applied to the power supply cover 300.

On the other hand, any one of the substrate cover 200 to the power supply cover 300, the ventilation means for preventing the internal circuits or components from being corroded or deteriorated or failure by enabling ventilation while maintaining the internal waterproof. 800 is provided.

That is, for example, as shown in FIGS. 8 and 9, the vent hole 280 is drilled in the substrate cover 200, and the ventilated waterproof member 810 is attached to the inner, outer, or both sides by the respective ventilation means 800. Will be installed.

The breathable waterproof member 810 is usually formed of a material in which a fluorine-based resin having excellent waterproofness is expanded to form a predetermined thickness of fabric, and the gap between the tissues is smaller than the minimum particle size of water droplets and the minimum molecules of air. Is molded larger than size

Accordingly, the breathable waterproof member 810 prevents the penetration of moisture and humidity from the outside, allows ventilation with the inside, discharges heat from the inside, and has a strong property of ventilation and heat resistance with the outside.

When the ventilated waterproof member 810 is attached to the substrate portion cover 200 by supplying an adhesive along its circumference to one side or both sides of the vent hole 280 as shown in FIGS. 8 and 9, Even when the remote control is exposed in a place with high humidity, such as a kitchen or bathroom, the waterproofness is maintained while maintaining the waterproofness.

Therefore, even if the cause of the generation of moisture in the casing 100 in accordance with the change in the temperature from time to time, moisture inflow by the ventilation function can be blocked and naturally dried by the ventilation function.

Therefore, various electronic components and circuits inside the remote controller can be protected from moisture while maintaining waterproofness.

In addition, it is also possible to prevent deformation due to moisture in the sealing portion of the casing 10 and the power supply cover 300 and the substrate cover 200 and the coupling portion of the various mechanisms.

Here, although the case of applying the structure of the ventilation means 800 to the substrate cover 200 is shown and described, it will be appreciated that the same structure can also be applied to the power supply cover 300.

According to the configuration of the present invention as described above, it is possible to protect the damage to the liquid crystal panel or other various electronic circuits and the sealing portion, while having a detachable installation of the substrate portion and the power supply cover, respectively, excellent waterproof function.

In addition, the partition wall 600 is excellent in strength, so that various circuits and structures accommodated in the board receiving portion 101 and the power receiving portion 102 can be further improved even when the breakdown voltage changes. It is a useful invention.
