Description

  The present invention relates to a home appliance charger using a rechargeable battery such as an ultrasonic toothbrush.

  A so-called home appliance charger such as an ultrasonic toothbrush can be connected to a power outlet with a predetermined length of power cord (usually around 1 m). When there is a power outlet nearby, the long power cord is used as it is, or the power cord is bundled.

  When there is a power outlet nearby, there is a problem that the long power cord gets in the way and gets caught on your feet. In addition, the power cord takes up extra space and is difficult to use.

  Therefore, a charger 1 as shown in FIG. 12 is known. In the electric circuit section 3, a charging circuit board (a charging circuit is omitted) 3-1 and a charging primary coil 3-2 are housed.

  As shown in FIG. 12B, the take-up reel 6 is formed by dividing the charger main body case 2-2 with a bottom plate 2-1. As shown in the figure, the take-up reel 6 is integrally attached to the bottom plate 2-1, and the main body case 2-2 is extended from the bottom plate 2-1 so as to expand from the bottom plate 2-1. And the end 7 is released. The reel 6 includes a winding shaft 6-1 of the power cord 4 and a reel frame 6-2 so that the wound power cord 4 cannot be unwound. Therefore, the charger 1 is placed at a predetermined position, the plug 8 attached to the power cord 4 is inserted into an outlet (not shown), and the excess power cord 4 is inserted into the winding shaft 6 as shown in FIG. 12B. It is recognized that the power cord 4 of the wound portion is intended not to be unwound by the skirt-shaped portion of the main body case 2-2 and the reel frame 6-2. In addition, the code | symbol 9 shown in FIG. 12 is a dish-shaped recessed part which fits the edge part of the handle part of an electric toothbrush (not shown).

  However, the structure of the charger 1 shown in FIG. 12 has a problem that the skirt-like portion and the reel frame 6-2 become an obstacle when the extra power cord 4 is wound up in use. When the charger is moved or falls due to the cause, there is a problem that the power cord 4 is unwound from the gap around which the power cord 4 is wound, and it is recognized that there is a doubt on practicality.

  The present invention has been made paying attention to the above problems, and in use, when the power cord attached in advance to the charger is too long, the unnecessary portion can be easily wound up in the charger. Moreover, it aims to provide a charger that can be melted and does not protrude outside.

  The charger with a power cord of the present invention for solving the above object is a charger for home appliances with a built-in rechargeable battery, in which a main body for storing a charging circuit portion and a power cord integrally attached to the main body are provided. A take-up reel for taking up the power cord, and the take-up reel is integrally attached to the main body, and the cord covers the take-up reel. A cover is detachably attached to the main body.

  The said household appliances said by this invention means comparatively small household appliances, such as an ultrasonic toothbrush, an electric toothbrush, a sonic toothbrush, an electric razor, a digital camera, a mobile phone, for example.

  The positional relationship between the main body and the winding unit may be either the vertical direction or the horizontal direction. There is no particular limitation on the means for integrally attaching the take-up reel to the charger body. However, since the charger is usually a plastic injection molded product, it may be integrally molded, but each unit may be screwed separately. Other means can also be used. As a means for making the cord cover detachable, for example, an elastic engagement means or any other means that cannot be easily removed can be used as appropriate.

  Since many small household appliances are generally used by being removed from the charger in use, it is preferable that the charger can be fixed. Therefore, the charger with the power cord of the present invention can be implemented by providing the cord cover with a screw hole for hanging on the wall for attaching to the wall. This simplifies the structure by combining the cord cover and the wall-mounting bracket, reduces costs, and further improves the workability because only the cord cover can be screwed first during the wall-hanging operation. it can.

  In the case where the home appliance is a product with poor installation such as being easily overturned, this draft can be implemented by providing a stand. In that case, the stand can be detachably attached to the charger body. If it does in this way, when dirt accumulates by removing a stand, the part can be cleaned easily.

  When the home appliance is a product that gets wet with water, such as an ultrasonic toothbrush, at least the charger main body is preferably a waterproof type. The waterproof type as used in the present invention includes not only a watertight and completely waterproof type, but also a structure in which water does not easily enter the charging circuit portion or the like when water flows down the surface of the main body.

  The charger with a power cord of the present invention has an extra power cord attached to the take-up reel provided on the charger body by removing the removable cord cover when the power cord attached in advance can be shorter for actual use. Since the power cord can be wound, it is easy to wind even if the charger body is smaller, and when the cord cover is attached, the wound power cord can be unwound and come out to the outside. The effect that it can prevent is produced.
