Abstract

PURPOSE:To perform rapid charging of a charging type vacuum cleaner and obtain a low-cost mother and child type vacuum cleaner by carrying out the charging of the separate charging type vacuum cleaner by means of a DC power source device provided in the exhaust passage of an AC type vacuum cleaner while dividing the output of this DC power source device in two systems and, at the time of operating the AC type vacuum cleaner, allowing a higher charging current than that at the time of stopping to flow. CONSTITUTION:A DC power source device 4 is provided in the exhaust passage in the rear of an AC motor-driven blower 2 and, at the time of installing a child cleaner 7 on a mother cleaner 1, a charging plug 13 and a charging jack 14 provided on the mother cleaner 1 and the child cleaner 7 respectively are mutually removably installed. The DC power source 4 has outputs of two systems and, at the time of operating the mother cleaner, it allows to flow a higher charging current than that at the time of stopping. The DC power source device 4 which is provided in the exhaust passage is cooled by an exhaust air flow at the time of operating the mother cleaner, with its temperature rise being suppressed to the degree of that at the stopping time of the mother cleaner and hence, a high charging current can be allowed to flow at the time of operating the mother cleaner, enabling the rapid charging of the child cleaner while miniaturizing the DC power source device 4 as well as lowering the cost of the vacuum cleaner.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a parent-child vacuum cleaner in which an AC vacuum cleaner is used as a parent vacuum cleaner and a rechargeable vacuum cleaner is used as a subsidiary vacuum cleaner.

2. Description of the Related Art A conventional parent-child vacuum cleaner is a parent-child bowl AC vacuum cleaner in which a child vacuum cleaner is detachably attached to a part of the parent vacuum cleaner. In this case, the power for the child vacuum cleaner is taken from the outlet or by the power cord from the parent vacuum cleaner.

On the other hand, in the case of a rechargeable vacuum cleaner, a built-in secondary battery is used as a power source and charged by an external DC power supply.

Problems that the invention aims to solve The conventional configuration described above has the following drawbacks.

1. In the case of the former parent-child vacuum cleaner, the child vacuum cleaner also requires a power cord, so the child vacuum cleaner remains inconvenient to use due to the power cord.

■In the case of the latter type of rechargeable vacuum cleaner, the faster the built-in rechargeable battery can be charged, the easier it is to use. From this point of view, the DC power supply itself must be made larger, resulting in higher costs.

The present invention solves these conventional problems and aims to provide a parent-child vacuum cleaner that is easy to use.

A means to solve problems The present invention solves the above-mentioned conventional problems.

A DC power supply device installed in the exhaust passage of an AC vacuum cleaner charges another rechargeable vacuum cleaner. In addition, the output of the DC power supply device is made into two series, and when the AC vacuum cleaner is operating, a higher charging current is passed than when it is stopped.
This is a device that quickly charges rechargeable vacuum cleaners.

Effect By taking the above-mentioned measures, the child vacuum cleaner does not have a power cord, which improves its usability. In addition, when an AC vacuum cleaner is operating, the DC power supply is cooled by the exhaust air, so a higher charging current can be passed when the AC vacuum cleaner is stopped without having to increase the size of the DC power supply. The purpose of the present invention is to provide a parent-child vacuum cleaner that is both rechargeable and inexpensive.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. 1 is an AC electric blower 2, a switch 3, and a DC power supply device 4
7 is a DC electric blower 8.
A rechargeable vacuum cleaner (hereinafter referred to as a child vacuum cleaner) consisting of a main body 11 having a switch 9, a battery 10, etc., and a dust collection chamber 12.
It is. The DC power supply device 4 is provided in the exhaust passage behind the AC electric blower 2. Reference numerals 13 and 14 denote a charging plug and a charging jack respectively disposed on the master vacuum cleaner 1 and the slave vacuum cleaner A, which are detachably attached to each other when the slave vacuum cleaner 7 is attached to the master cleaner 1.

Here, as shown in the circuit diagram of FIG. 2, the DC power supply device 4 has two outputs when the main vacuum cleaner is in operation.

It is configured so that a higher charging current flows than when it is stopped.

As is clear from the above configuration, since the DC power supply device 4 is provided in the exhaust passage, when the main vacuum cleaner is in operation, it is cooled by the exhaust air and the temperature rise is suppressed to the level when the main vacuum cleaner is stopped. Therefore, a high charging current can be passed during operation of the master vacuum cleaner, allowing for rapid charging of the slave vacuum cleaner, miniaturization of the DC power supply device 4, and cost reduction.

Effects of the Invention As described above, according to the present invention, it is possible to provide a parent-child type vacuum cleaner that has a simple charging configuration, is easy to use, allows for rapid charging of a rechargeable vacuum cleaner, and is inexpensive.
