Abstract

PURPOSE:To prevent a hose from getting blocked with a dust due to lowering of a suction force before the hose is pulled out by cutting off a power, when one of electric blower is to be switched off, to one electric blower after a setting time set by a delay timer circuit. CONSTITUTION:When a switch 18 at hand is closed after a hose is inserted into one hose socket, a resister value detection circuit 14 detects this and sends a signal to a make and break circuit 12 and electric power is applied to one electric blower for enabling a cleaning at normal capacity. When the switch 18 at hand is closed after hoses are inserted into two hose sockets at the same time, the resister value detection circuit 14 detects this and sends a signal to the make and break circuit 12, and electric power are applied to both electric blowers for enabling both hose sockets to perform cleaning at normal capacity. Next, when one switch 18 at hand is opened, a power to an electric blower is cut off after appropriately setting time set by a delay timer circuit 13.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a central cleaner.

Conventional technology As shown in Figure 3, conventionally, a main unit containing an electric blower, a dust collection box, a remote control device, etc. was installed in one place in a house, and another was installed in a room, hallway, etc. of the house as appropriate. Many so-called central cleaners have been devised and implemented, in which cleaning hoses 0.2A, 2B, 2C, and 2D are connected by a plumbing pipe 3, and cleaning can be performed simply by inserting the hoses.

Problems to be Solved by the Invention In this conventional central cleaner, two
There was a problem that it could not be used with more than one outlet. In other words, if you try to clean by inserting a hose into two outlets at the same time, the suction air volume at the end of each hose will be 1/2, and not only will the air volume necessary for cleaning not be obtained, but also This had the problem of clogging with trash.

In order to solve this problem, it may be possible to install a high-capacity electric blower, but in this case, the suction air volume and vacuum pressure would be too large when used with one outlet, and the suction device would be placed on the floor, etc. Another problem was that the adsorption force was large, making it difficult to operate.

The present invention solves the above-mentioned problems of the prior art, and allows cleaning to be performed at an appropriate level even when used in several locations at the same time.

The prior art will be explained using FIG. 1 of the present invention.

When a hose is inserted into one hose outlet, for example two people, and the hand switch l♂ is closed, the resistance value detection circuit l≠
detects this and sends a signal to opening/closing circuit/2, which energizes one electric blower and allows cleaning to be performed at normal capacity. When the hoses are inserted into the two outlets at the same time and the hand switch IT is closed, the resistance value detection circuit l≠ detects this and sends a signal to the opening/closing circuit 12, which energizes the two electric blowers to close both outlets. Both can be cleaned by applying electricity.

However, even if you finish cleaning one place and open the hand switch to stop one of the electric blowers, unless you pull out the hose, only the remaining electric blower will continue to blow air from the two outlets. It has been found that this results in a disadvantage that the suction force is reduced and the inside of the plumbing pipe becomes clogged with dirt.

Also, for example, out of two electric blowers, the one that is energized at the cleaning center has a significantly longer energization time than the one that is energized only when there are only two outlets, so its lifespan is shortened. This causes a significant imbalance in the lives of both electric blowers, resulting in a shortened lifespan of the central cleaner as a whole.

The present invention solves the above-mentioned conventional problems by continuing to energize the electric blower until the hose is removed from the outlet, making the energization time of the two electric blowers equal,
The purpose is to extend the life of the entire central cleaner.

Means for Solving the Problems The present invention provides a plurality of electric blowers installed in a part of a house,
An opening/closing circuit that controls the electric blower, a resistance value detection circuit that detects when the hand switch of the hose inserted into the outlet is closed and sends a signal to the opening/closing circuit, and a resistance value detection circuit that detects the closure of the hand switch of the hose inserted into the outlet and sends a signal to the opening/closing circuit; The main unit, which has a built-in delay timer that operates when the timer decreases, is connected to a cleaning hose outlet installed appropriately in a room, hallway, etc. of the house using a plumbing pipe, and the number of hoses inserted into the outlet is determined by the resistance value. Detecting with a resistance value detection circuit, energizing the electric blower, and when the number of electric blowers decreases, opening a hand switch of the hose, and then using a delay timer circuit to temporarily continue energizing the electric blower with the switch open; A resistance value detection circuit that detects the resistance value of a plurality of electric blowers installed in a part of a house, an opening/closing circuit that controls the electric blowers, and a hand switch circuit of a hose that is inserted into an outlet;
The main unit, which has a built-in integration timer circuit that totals the energization time for each electric blower, is connected to a cleaning hose outlet installed in a room, hallway, etc. of the house using a plumbing pipe, and the hose is inserted into the outlet. The number of electric blowers installed in a part of the house is detected by the resistance value detection circuit based on the resistance value, and the electric blowers that have been energized for a short time are sequentially energized through the integration timer circuit. A main body that has a built-in blower, an opening/closing circuit that controls the electric blower, a resistance value detection circuit that detects the resistance value of a hand switch circuit of a hose inserted into the outlet, and an integration timer circuit that adds up the energization time for each electric blower. , connect cleaning hose outlets appropriately installed in rooms, hallways, etc. of the house with plumbing pipes, detect the number of hoses inserted into the outlets by the resistance value, and use the resistance value detection circuit to set the integration timer. The electric blowers that have been energized for the longest time are sequentially stopped via a circuit.

action The effects of the above configuration of the present invention are as follows.

1. When the number of electric blowers changes from two to one, the power to one electric blower is cut off after an appropriately set time using a delay timer circuit, so the suction force is reduced until the hose is pulled out. There is no possibility of dirt clogging due to decrease in the amount of water.

2. By equalizing the energization time to each of the two electric blowers, the life of the entire central cleaner can be extended.

Embodiment FIG. 1 shows a block diagram of the configuration of a first embodiment of the central cleaner of the present invention.

The central cleaner of the present invention is similar to the conventional example, as shown in FIG.
This is done by connecting cleaning hose outlets installed appropriately in rooms, hallways, etc. of a house with plumbing pipes.

There are two electric blowers 11 inside the main body of the central cleaner. A resistance value detection circuit l≠ including an opening/closing circuit/2S delay timer circuit 13 and a remote control circuit for controlling the electric blower/l is built-in. The resistance value detection circuit l≠ containing the remote control circuit is connected to a cleaning hose outlet installed appropriately in a room, hallway, etc. of a house via a remote control wiring /j routed along a plumbing pipe. The terminal 16 is connected to the terminal 16.

Reference numeral 17 is a reinforcing wire for the hose, which also serves as a signal wire for remote control. /r is a hand switch, and 1lrA is a hand switch circuit.

The operation of the first embodiment of the present invention will be explained.

When a hose is inserted into one hose outlet and the hand switch /I is closed, the resistance value detection circuit l≠ detects this and sends a signal to the opening/closing circuit 12, which energizes one electric blower and returns it to its normal capacity. You can clean it with When the hoses are inserted into the two outlets at the same time and the hand switch /I is closed, the resistance value detection circuit /≠ detects this and sends a signal to the opening/closing circuit /2, which energizes the two electric blowers to both Both outlets can be cleaned with normal capacity.

Next, there is a hand switch for the hose at one outlet.
When opened, the power supply to one electric blower is cut off after an appropriately set time by the delay timer circuit 13.

A block diagram of the configuration of a second embodiment of the present invention is shown.

The sand crane cleaner of the present invention is similar to the conventional example, as shown in FIG.
This is done by connecting cleaning hose outlets installed appropriately in rooms, hallways, etc. of a house with plumbing pipes.

Built-in the main body of the central cleaner are two electric blowers //, an opening/closing circuit 12 that controls the electric blowers //, an integration timer circuit, and a resistance value detection circuit that includes a remote control circuit. . Resistance value detection circuit including remote control circuit/II- is remote control wiring routed along the plumbing pipe/j
It is then connected to a terminal/B installed in a cleaning hose outlet installed appropriately in a room, hallway, etc. of a house. Reference numeral 17 is a reinforcing wire for the hose, which also serves as a signal wire for remote control. /r is a hand switch.

The operation of the second embodiment of the present invention will be explained.

When a hose is inserted into one hose outlet and the hand switch IT is closed, the resistance value detection circuit ≠ detects this and sends a signal to the integration timer circuit ≠, which calculates the cumulative energization time of each electric blower. A signal is sent to the opening/closing circuit 12 to energize the electric blower with the smaller amount, and one electric blower is energized to perform cleaning with its normal capacity. When the hose is inserted into the other outlet at the same time and the hand switch IT is closed, the resistance value detection circuit/Hiroshi detects this and sends a signal to the opening/closing circuit 12, which energizes the other electric blower. Both outlets can be cleaned at normal capacity.

Next, switch the hose at one outlet/r.
When it is opened, the resistance value detection circuit/≠ detects this and sends a signal to the integration timer circuit/ri, which determines the cumulative energization time of each electric blower and sends a signal to the electric blower with the greater amount of energization time. Sends a signal to switching circuit/2 to cut off the current,
Only one electric blower is energized again.

Effects of the Invention In the present invention, when the number of electric blowers to be energized decreases, a delay timer is used to continue energizing for a while. During this time, the air volume of both hoses will be reduced to 1/2, and those who do not open the hand switch, that is, those who continue cleaning, will not only be unable to clean, but will also be unable to clean due to the reduced air speed inside the pipes. This can prevent problems such as clogging.

In addition, when the central cleaner of the second embodiment of the present invention energizes one electric blower, it always energizes the one with the shorter cumulative energization time, thereby making the energization time of the two electric blowers equal and equalizing their lifespans. This is what made it possible. Naturally, this has the effect of extending the life of the central cleaner as a whole.

Furthermore, when switching power from two electric blowers to one electric blower, the current is always cut off to the one that has been energized for the longest time, thereby making the energization time of the two electric blowers equal, resulting in a longer life. This has the effect of increasing
