Description

[Detailed description of the invention]

B) Industrial Application Field The present invention relates to a sentful cleaner system configured by connecting a hose outlet provided in each room to a stationary cleaner body via intake piping and electrical wiring.口) Conventional technology Conventionally, this type of centrifugal cleaner system has
The same power is used whether cleaning a room close to where the cleaner is installed or a room far away. As the distance between the cleaner main body and the hose insertion port becomes longer, the air volume decreases due to conduit resistance between them. Therefore, regardless of the distance between the room to be cleaned and the cleaner body, the electric feed +aai' of the cleaner body is turned on.
If you only want to control F, use the hose outlet in a far room (
The vacuum level of the vacuum cleaner (or suction port) also decreases, making it impossible to suction dust, but when cleaning a room near the main body of the cleaner, full power is required, resulting in a large loss of power consumption. 8] Purpose of the Invention The object of the present invention is to automatically control the output of the °C cleaner body depending on the distance between the cleaner body and the room to be cleaned, so as to perform appropriate suction work. 2) Structure of the Invention The present invention has a central cleaner cage configured by connecting an L/π hose outlet installed in each room and a stationary cleaner main body through intake piping and electrical wiring. The pressure difference between the hose insertion port and the intake port of the cleaner body is detected by a pressure sensor L/, and the rotation speed of the electric blower of the cleaner body is controlled by this detection signal via an automatic control circuit. It is. e) Examples The present invention will be explained below with reference to the drawings. ('') is a house with multiple rooms L2) (2+...
+31 is a stationary type cleaner that is installed outdoors under the eaves, etc. The main body has two approximately U-shaped parts: F and 1 ton! I 141
A main body case (6) supported by +41 and containing an electric blower (5), and a bottomed cylindrical dust collector detachably connected to the lower part of the main body case by a pair of clamp means (7) (7). A case (81) and a filter (11) which is suspended and supported by a ring-shaped waiting frame (91) are installed in the dust collection case.
1 and Q3 are exhaust ports and intake ports provided on the sides of the main body case (61 and dust collection case (8). 03031... is each room in the house 1)

Connect the outlet and the cleaner body 1 with a π hose outlet.
31 is connected to the intake pipe A4 and the electrical wiring (15+).The hose insertion 003 is connected to the extension pipe Aη and the floor suction port U81T via the flexible hose T161.

Each hose outlet 03 is normally closed with a lid U9 that can be opened and closed, but only when cleaning is to be done, the attachment U9 is opened to connect the flexible hose (161). is stored in the main body case (6) Electric air blower HA 16+
This is an automatic control circuit section that controls the rotation speed of a power control element such as a thyristor (
Wow, semiconductor pressure sensor G! 3 [,! 41 and four other circuit components. The semiconductor pressure sensor C3124+ is installed at the intake port az of the cleaner body (3) and each hose insertion port 03, and the π pressure sensor tube c! e @ and flexible pressure transmission pi force Δ (to)
The output, T, or rotation speed of the electric blower (61) is controlled via the automatic control circuit section (■) based on the pressure difference detected by the two pressure sensors (1). Figure 4 1: As shown, the pressure difference between the semiconductor pressure sensor (C) (2) is detected by the comparator ω, and this detection signal is amplified by the amplifier (2). The controller including Q3) is configured to control the °C electric blower (61).That is, if the pressure difference detected by both pressure sensors (C) (2) is larger than the reference pressure difference, The output of the electric blower (6) is increased. tπ If the detected pressure difference is smaller than the reference pressure difference, it functions to reduce the output of the electric blower (6). Next, the operation will be explained. First, clean. 2) Hose insertion port 031 of the room to be used: Connect the floor suction port 031 via the flexible hose A8 and the extension pipe on, and install it in the grip of the flexible hose 116+ to the remote When a switch (not shown) is turned on, the electric blower (6) of the cleaner body 13) is driven. As a result, the dust sucked from the sand in the floor suction port A is carried to the cleaner body (3) via the air flow (second extension pipe O7) and the flexible hose (161, intake pipe I), where it is collected. It accumulates in the case (8).The air flow separated by the filter (li) is discharged to the outside from the exhaust port at+ of the main body case (6).
21, the suction force of the floor suction port 1181 decreases due to the pipe resistance of the intake pipe I, but the present invention
The temperature is determined by detecting the pressure difference between the intake port (121) of the cleaner main body 13+ and the hose insertion port 03 using the semiconductor pressure sensor @, and using this detection signal to control the power control element I22.
1 ° [Electric air blower AL16]
Since the output of 1 is increased, if the surface to be cleaned gets too close and the floor suction port A81 is closed while the cleaning can be done without any trouble, the air intake port A3 of the cleaner body (3) and the hose insertion port will be closed. (As the pressure difference between 131 and 131 becomes smaller, the output of electric blower 61 is automatically reduced by the automatic control circuit, and the suction of the floor suction port UGJ is released, allowing the cleaning work to continue.) Of course, the cleaner body (3 ) Room (21) on the first floor near
When cleaning the cleaner body 13), the air intake port t1
The pressure difference between 3 and hose outlet 03 is small, and the output of the electric blower (6) can be saved and maintained at an appropriate level by the action of the automatic control circuit that includes the power control element. . f. Cleaning area: If large debris is accidentally sucked in, the pressure detection tube (rib) of the hose insertion port 03 will become electrified, and the output of the electric blower (61) will also decrease rapidly, causing the flexible If the hose 1161 is pulled out and large debris is removed, the normal operating condition will be restored quickly. f) Effects of the Invention Since the centful cleaner system according to the present invention is constructed as described above, the cleaner Regardless of the distance of the room being cleaned from the main body, cleaning can be done with approximately the same suction power in any room. The present invention eliminates the problem of excessive suction caused by the suction port, which has practical effects such as shortening cleaning time and saving energy.
