Abstract

PURPOSE:To exactly detect the refuse-clogged place and to exactly eliminate the clogging refuse by placing a pressure sensor in plural places of a fixed piping part, deciding a detected pressure signal level by a deciding part, and displaying its result. CONSTITUTION:In a fixed piping part 4, pressure sensors 8 of P1-P5 are placed in important points. A pressure signal detected by each pressure sensor passes through a sensitivity adjusting part 10 and a deciding part 11 and displays a result of its decision on a display part 12, and informs a refuse-clogged place. According to this constitution, when a refuse clogging is generated in the fixed piping part, pressure in the piping is varied, comparing with the pressure before generation, therefore, the pressure signal obtained from the pressure sensor is also varied. Accordingly, by comparing and deciding a decision level set in advance and the pressure signal obtained from the pressure sensor, whether a refuse clogging is generated or not can be decided. Also, pressure in the piping in each pressure sensor fitting position is different in accordance with the fitting position, therefore, it is desirable that the decision level is adjusted in advance by providing the sensitivity adjusting part on every pressure sensor.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for installing suction piping and for connecting a cleaning hose to the suction piping.

BACKGROUND OF THE INVENTION Conventionally, this type of central cleaner device has had a configuration as shown in FIG. As shown in the figure, a vacuum cleaner body 1 with a built-in suction fan has an intake port 2 and an exhaust port 3.
A hose connection port 5 to which a cleaning hose 7 is connected is connected to the fixed piping section 4.

In such a central cleaner device, cleaning inspection holes 6 are provided at important points as shown in Fig. 4 in order to remove the clogged garbage in the event that the fixed piping section 4 becomes clogged with garbage. It was getting worse. If the fixed piping section 4 is clogged with dirt, the clogged dirt can be removed by inserting a cleaning tool as shown in FIG. 5 through the hose connection port 5 or cleaning inspection port 6 shown in FIG. It was structured like this.

Problems to be Solved by the Invention In general, the length of the fixed piping section is from several tens of meters to several hundred meters.
Even if a dirt clog occurs in a fixed piping section, it is difficult to know exactly where it occurs. In addition, the fixed piping section is
It is located under the floor of a house, and cleaning work through the cleaning inspection port is not easy and the workability is not good. Therefore, it was necessary to improve work efficiency by knowing exactly where the dirt clog occurred and inserting a cleaning tool from the vicinity to clean it.

SUMMARY OF THE INVENTION The present invention is intended to solve these problems, and it is an object of the present invention to provide a central cleaner device that can accurately detect the location where dirt is clogged and can remove the dirt clog appropriately.

Means for Solving the Problem In order to solve this problem, the present invention arranges a plurality of pressure sensors in a fixed piping section at important points, and uses a determination section to determine the pressure signal level detected by each pressure sensor. , the user is notified of the determination result by displaying it on the display unit.

Further, after the pressure signal detected by each pressure sensor is set at a level corresponding to the pressure sensor installation position in the sensitivity adjustment section, the determination section makes a determination.

Effect: With this configuration, when dust clogging occurs in the fixed piping section, the pressure inside the piping changes compared to before the clogging occurs, so the pressure signal obtained from the pressure sensor installed inside the piping also changes. Therefore, by comparing and determining the predetermined determination level and the pressure signal obtained from the pressure sensor, it is possible to determine whether or not dirt clogging has occurred.

Furthermore, by displaying the above determination results on the display section corresponding to each pressure sensor, it is possible to easily and accurately know the location where the dirt is clogged.

In addition, the pressure inside the piping at each pressure sensor installation position differs depending on the installation position of the pressure sensor even if there is no dust clogging. By adjusting the level in advance, it is possible to more accurately determine whether there is a clog with dirt.

Embodiment FIG. 1 shows an embodiment of the present invention. As shown in the figure, pressure sensors 8 P1 to P5 are arranged at important positions in the fixed piping section 4. The pressure signal detected by each pressure sensor passes through a sensitivity adjustment section 10 and a determination section 11, and the determination result is displayed on a display section 12 to notify the location of the clogged dirt. Sensitivity adjustment and determination can also be performed simultaneously using a comparison amplifier.

FIG. 2 shows the operating principle of the central cleaner device shown in FIG. 1. As shown in the figure, when the cleaning hose 7 is inserted into the hose insertion port 5b and operated, the pressure distribution at each point P1 to P5 when there is no dirt clogging in the fixed piping section 4 is shown in Figure 2 ( It becomes as shown by the solid line of bi.Therefore,
If the judgment level for each point of P1 to P5 is set as shown by the dotted line in FIG. 2 (bl), the display section 12 in FIG. 1 will not light up at all. The display section 12 does not light up even if it is inserted.

Next, when a dust blockage occurs between 12 and 14, when the cleaning hose 7 is inserted into the port insertion port 5a, the pressure distribution will be as shown by the solid line in Figure 2 (C), and the pressure distribution will be as shown by the dotted line. When such a determination level is set, the display section 12 lights up as shown in the upper row of Table 1.

When a hose is inserted into the insertion port 5a, it is displayed as 1st-back lower row.

If a garbage blockage occurs between 24 and 25, the second display will be displayed.
Table 3 shows the display when dust clogging occurs between 22 and 23. As can be seen from the table, depending on the display state of the display section 1.2, the location of the clogged dirt can be easily determined, and the work of removing the clogged dirt can be carried out appropriately.

1 Display when a dust blockage occurs between Tables 12 and 14 Display box when a dust blockage occurs between Tables 22 and 23 Table 1) Display when a dust blockage occurs between Tables 22 and 23 Effects As is clear from the above description of the embodiments, according to the present invention, it is possible to accurately determine the location where dust clogging occurs in fixed piping.

That is, as in the above embodiment, with the conventional technology, it is not possible to distinguish between the garbage clogging that occurred between 22 and 24 and the garbage clogging that occurred between 24 and 25, but according to the present invention, it is possible to easily distinguish between be able to.

Further, by computer processing the patterns of pressures detected by the various pressure sensors as described above, it is possible to more quickly display and notify the location of the clogged dirt.
