することにある。When an infrared remote controller is built in a hand operation unit of a vacuum cleaner, the hand operation unit is obliquely positioned with respect to a floor surface because a suction port and an extension tube are connected and used for practical use. Therefore, it is necessary to adopt a method in which the infrared ray transmitted from the hand operation unit is reflected from the ceiling surface and received by the cleaner body. In the structure of the operation unit at hand, it is necessary to provide a control board with an infrared LED and a changeover switch at a position parallel to the operation display unit. It cannot emit infrared light. If the light-emitting part cover that transmits infrared rays with the above structure is made substantially parallel to the operation display part, the light will be totally reflected if it exceeds the critical angle, so if you do not plan with an appropriate shape, the reliability of the product will be low. Become. In addition, if the shape and structure are complicated to increase the reliability, the cost increases. SUMMARY OF THE INVENTION It is an object of the present invention to provide a structure of a hand-held operation unit in which a hand-held operation unit has a built-in infrared remote control for transmitting and receiving to and from a vacuum cleaner, which has high reliability, is inexpensive, and has good assemblability. It is in.

で安全性も高く意匠的にも優れている。An embodiment of the present invention will be described below with reference to FIG. Reference numeral 1 denotes a bent joint, which forms a handle 3 in combination with the joint cover 2, and furthermore, a hose mounting portion 21 and a battery housing portion 22 are integrally formed. Reference numeral 4 denotes an operation button formed integrally with the joint cover 2 so that the control board 5 can be operated to adjust the suction force. Reference numeral 6 denotes a clamp button for connecting and holding an extension pipe connected to a floor suction port or the like. Reference numeral 7 denotes a joint packing locking member for locking the joint packing 24, which keeps the bent joint 1 and the extension pipe 34 airtight. Reference numeral 8 denotes a screw for fixing the bent joint 1 and the joint cover 2, reference numeral 29 denotes a seal for blindfolding the screw 8, and reference numeral 9 denotes a battery cover which is attached to the battery housing 22 to form a housing. Terminals (covers) for electrical connection with the battery 10 are fixed to the battery cover 9. 1
Reference numeral 1 denotes a terminal having a spring property for performing electrical conduction similarly to the terminal (cover). Reference numeral 18 denotes a case for holding a substrate having 19 LEDs. A hose hooking member 15 is attached to the hose mounting portion 21 on a flexible hose 12 having a helical protrusion, and a packing hooking is provided to fix the packing member 13 for the purpose of maintaining airtightness to the hose hooking member 15. The member 14 is positioned on the outer periphery of the packing member 13, inserted into the hose mounting portion 21, and the claw portion 30 provided on the hose stopper 16 is locked and mounted in the locking hole 17 provided on the hose mounting portion. . Reference numeral 31 denotes a spring for always regulating the position of the clamp button 6, reference numeral 26 denotes a terminal retainer for preventing the terminal 11 from coming off, and reference numeral 28 denotes a light emitting unit cover formed of a material that transmits infrared rays and having a spherical shape. Reference numeral 27 denotes an operation display sheet on which an operation display is printed, covers the operation buttons 4 and, at the same time, affixes the entire periphery of the flange portion provided integrally with the light emitting unit cover 28. The operation of the above structure will be described. When an operation button is pressed to operate the cleaner main body, infrared light is incident on the light emitting unit cover 28 from the infrared light emitting LED 23 attached to the control board 5. In order to transmit infrared rays effectively, it is necessary to prevent total reflection. Generally, plastic resin is used in a wide range as a material for the light emitting unit cover, and the total reflection critical angle sinα =
It is represented by 1 / n (refractive index: n). When the light is incident at an angle larger than the critical angle α, a part of the light is totally reflected and not transmitted. FIG. 5 is an explanatory diagram for obtaining an incident angle. B indicates the center of curvature of the light emitting unit cover, and A indicates the center of light emission of the infrared light emitting LED. C and D are infrared light emitting LE
This is the intersection point between the directivity angle θ as the characteristic of D and the inner peripheral surface of the light emitting unit cover. The incident angle needs to be calculated for the outermost angles C and D of the directivity angle θ, but it is certain that the incident angle is determined to be larger. In the illustrated case, α1> α2, so that if α1 is smaller than the critical angle α, the light can be transmitted effectively.
When molding the light emitting unit cover with ABS resin, the critical angle is about 3
8.1 ° -39.1 °, 42.16 for acrylic resin
°, a structure that falls within this angle may be used.
In the conventional structure shown in FIG. 4, the angle of BCA in FIG. 5 was larger than the critical angle and some infrared rays were totally reflected. However, in one embodiment of the present invention, the light emitting unit cover is located above the upper surface of the joint cover. Α1 and α2 can be made small angles, and total reflection can be prevented. The assembling has a structure in which the front and rear claws provided on the light emitting unit cover 28 are pressed into the grooves of the joint cover 2 and the operation display sheet is simply attached from above, so that the cost is low and the assembling is easy. is there. Further, since the flange portion provided integrally with the light emitting portion cover 28 is covered and fixed with the operation display sheet, water droplets do not penetrate into the joint cover 2, so that the safety is high and the design is excellent.
