Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upper body provided at an upper portion of a main body case having a dust collection chamber and a motor chamber, a storage unit for storing a replacement nozzle and a cover for covering the storage unit. The present invention relates to an electric vacuum cleaner having a movable storage lid and a brake button for activating a brake of a cord reel.

2. Description of the Related Art As shown in FIG. 5, a conventional electric vacuum cleaner uses a front fixing portion 4 of the storage lid 3 in order to open the storage lid 3 that covers the replacement nozzles (shelf nozzle 1, gap nozzle 2). When opened, the leaf spring 6 attached to the rear portion of the upper body 5 pushes out the protrusion 7 provided on the rear rear surface of the storage lid 3 to rotate the storage lid 3 in the arrow A direction.

Problems to be Solved by the Invention However, in the case of such a structure, the leaf spring 6 cannot be largely deflected because the leaf spring 6 is always loaded with the storage lid 3 closed. . Therefore, when the leaf spring 6 is used, a stroke for rotating the storage lid 3 largely cannot be obtained.

Further, when the leaf spring 6 is attached to the upper body 5, since the leaf spring 6 is sandwiched and fixed as shown in FIG. 5, it is difficult to insert the leaf spring 6 during assembly, and the leaf spring 6 is vibrated due to vibration.
Could come off.

Further, since the leaf spring 6 is held and fixed to the upper body 5, there is a problem that a cut portion of the main case 8 that is difficult to face the motor chamber 9 is formed, which causes exhaust leakage.

Further, since the leaf spring 6 is used, there is a problem that the number of parts and the number of assembling steps increase.

The present invention solves such a conventional problem, and by using the spring elasticity of the brake button that operates the brake of the cord reel, the storage lid can be opened without providing a leaf spring or a protrusion as in the conventional case. An object of the present invention is to provide an electric vacuum cleaner that can be rotated upward.

Means for Solving the Problems In order to solve the above problems, the present invention relates to a main case having a dust collection chamber and a motor chamber, a storage unit that covers the motor chamber, and stores a replacement nozzle and a cord reel. An upper body in which a vertically movable brake button for activating the brake is arranged, and a storage lid which is rotatably attached to the upper body to open and close the storage portion and in which a hole facing the brake button is formed partially. A holding means for holding the closed state of the storage lid is provided, and the brake button is urged upward by a coil spring, and is set so as to cooperate with the brake with a predetermined play when the brake button is moved downward. Further, the storage lid is provided with locking means for holding the brake button in the downward movement state within the play range when the storage lid is in the closed state.

Action The action of the above configuration is that when the storage lid is held by the front fixing portion, the brake button is fixed downward while holding the length corresponding to the rotation stroke. When the brake button is pushed down, the brake is released and the cord reel is rolled in. When the brake button is released, the brake is activated and the cord reel is fixed. Also, when opening the storage lid, if the front fixing portion of the storage lid is opened, the brake button is pushed upward by the urging force of the spring by the stroke of pushing the storage lid, and the flange portion of the storage lid is Since it is in contact with the brake button, the storage lid rotates upward about the rotation shaft. Further, when the storage lid is closed, the storage lid is brought into contact with the brake button, so that the brake button is pushed downward and the storage lid is held and fixed by the front fixing portion.

According to the above configuration, since the storage lid can be rotated upward without using a component such as a leaf spring for rotating the storage lid, the assemblability and the cost can be improved. . Further, since the coil spring for sliding the brake button is used, a longer rotation stroke of the storage lid can be secured as compared with the leaf spring. Further, since the storage lid positions the brake button up and down, it is easy to manage the protrusion of the brake button from the top surface of the storage lid and the dent in terms of appearance. Furthermore, in terms of appearance, since it is not necessary to show the installation location of the leaf spring on the upper body or to provide the protrusion on the back surface of the storage lid, it has an excellent effect such as good appearance.
