Working Handle For Central Vacuum System

(Technology)

The present invention relates to a work handle of the centralized vacuum cleaner, and more particularly, the operation handle of the dust collector is displayed on the work handle which always pays attention during the cleaning operation, so that the operation of the centralized vacuum cleaner is excessive. This invention relates to a work handle of a centralized vacuum cleaner, which can prevent damages in advance and allow for after-sales service in a timely manner.

(Background)

Unlike the traditional mobile vacuum cleaners, which have been dragged from place to place for cleaning, the centralized vacuum cleaner is fixedly installed with a vacuum cleaner and a vacuum cleaner with a vacuum motor and a filter in a separate space. The central dust cleaning system is used by connecting vacuum cleaners (work handles) to the suction pipes when the cleaning pipes are connected to the suction pipes.

As shown in Figures 4 and 5, a general centralized vacuum cleaner (1) is fixed to a warehouse, a garage, a veranda, etc., a dust collector (2) having a vacuum motor (3) and a filter (4), the dust collector (2) from the suction pipe (5) which is piped in the ceiling or wall from the various places in the room, a plurality of suction ports (6) installed in various places in the house where the end of the suction pipe (5) is located, and the suction port (6) It is configured to include a variety of work handles (7), such as a cleaning brush detachably connected to the operating brush (8) equipped with a strong suction force of the large-capacity dust collector (2) of the house through the suction pipe (5) It is used in such a way to deliver to some places and to filter the dust sucked through the work handle (7) and the suction port (6) with a filter of the dust collector (2) to discharge some fine dust to the outdoors.

The central dust vacuum cleaner 1 does not need to move the dust collector 2, and since the dust collector 2 is located in a separate space 9 such as a warehouse, the vacuum motor and filter noise are almost inaudible. It is possible to clean various parts of the house by simply attaching and removing the handle (7) to the inlet (6), and equipped with a powerful vacuum motor and a large-capacity filter, the cleaning effect is very excellent. Compared to this, maintenance cycles such as filter replacement and dust box cleaning are considerably longer, which makes it easier to manage and use. Since the dust collector (2) is installed in a separate space, there is almost no dust circulating in the room during the cleaning process. In particular, the use of the high-end housing is increasing due to various advantages, such as a significant reduction in labor required for cleaning.

As with all equipment, in order for the centralized vacuum cleaner 1 to function optimally, the vacuum motor 3 and the filter 4 mounted on the dust collector 2 must be kept in a normal state, and thus the regular Maintenance is essential.

One of the most important during the periodic inspection of the centralized vacuum cleaner (1) is that the motor brush (3A) and filter (4) of the dust collector (2) is periodically replaced before the end of its service life The lifespan of the motor brush 3A and the filter 4 is notified to the user by specifying the product or an instruction manual. However, it can be said that it is practically impossible for the user to grasp the cumulative usage periods of the motor brush 3A and the filter 4 by themselves and replace them at an appropriate time.

As one of the methods for solving the management problems of the central dust collecting vacuum cleaner 1, the central dust collecting type installed in the dust collector 2 is provided with an operation state display unit which displays the replacement time of the motor brush 3A or the filter 4; Vacuum cleaners have been developed.

However, since the dust collector 2 is installed in a separate space such as a warehouse, a garage, a veranda, etc., which is isolated from the daily living space, and general users lack technical knowledge and understanding of the centralized vacuum cleaner 1, If you deliberately go to the place where the dust collector (2) is installed and look at the operation status display part and replace the motor brush (3A) or filter (4) in time, it is not possible to replace the motor brush or filter at the appropriate time. Often, the life of the device is shortened and the optimum cleaning effect is not achieved.

As shown in FIG. 6, the operation of the central dust type vacuum cleaner 1 is performed by wire or wirelessly through an operation control unit 8 of the work handle 7 equipped with an on / off switch and a flow rate control switch. Is common.

In the wired method, a low voltage wire is wired between the dust collector 2 and the suction port 6 along the suction pipe 5 so that power is supplied to the operation control unit 8 when the work handle 7 is inserted into the suction port 6. It is configured such that, when operating the operation operation unit 8 of the work handle 7 is adjusted on / off and the air volume of the dust collector (2).

In the wireless system, the wireless transmission unit capable of remote control is mounted on the operation control unit 8 of the work handle 7 and the dust collector 2 is equipped with a wireless receiver instead of using low voltage wiring. By operating the operation control unit 8 of (7), the on / off and air volume of the vacuum motor is controlled by the RF radio signal.

An object of the present invention is to solve the problems related to the use management of the centralized vacuum cleaner as described above, by allowing the user to easily determine the replacement time and inspection of the dust collector motor brush or filter, It is intended to prevent the shortening of the life of the centralized vacuum cleaner or the deterioration of performance due to proper management delay.

Can be configured.

The work handle of the present invention preferably causes the display unit to be operated by an abnormal operation signal of the vacuum motor or the filter transmitted from the dust collector to the wired / wireless device so as to inform the user that the vacuum motor or the filter needs to be inspected. Do.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation handle of the central dust collecting vacuum cleaner according to the present invention. The following embodiments are only illustrative of the work handle according to the present invention is not intended to limit the scope of the present invention.

1 is a schematic view of an exemplary work handle according to the present invention, FIG. 2 is a block diagram of an exemplary driving state display device applied to the work handle of the present invention, and FIG. 3 is a view showing examples of a display unit.

As shown in FIG. 1, the work handle 10 according to the present invention is a work handle 10 such as a cleaning brush that is detachably connected to the inlet 6 of the centralized vacuum cleaner 1 and used. ) Is characterized in that it comprises at least an operation state display device 20 which informs at least the replacement time of the motor brush 3A and the filter 4 of the vacuum motor 3. In other words, the work handle 10 of the present invention is the dust collector 2 from the moment when the motor brush 3A or the filter 4 is newly mounted to the dust collector 2 through the operation state display device 20 provided therein. If the cumulative usage time of the motor brush 3A or the filter 4 matches the appropriate usage time (life time), the service life of the motor brush 3A or the filter 4 is extended. Mark it as expired so it will be recognized.

As shown in FIG. 2, the driving state display device 20 applied to the work handle 10 of the present invention includes a predetermined use time measurement unit 30, a display unit 40, and a reset switch unit 50. It consists of a circuit of.

If the cumulative use time measurement unit 30 is configured to measure the cumulative use time of the dust collector 2 and operate the display unit 40 when the cumulative use time reaches a reference time (the life of the motor brush or the filter). It is not particularly limited.

As an example of the cumulative usage time measuring section 30, the clock generation section 31 and the clock generation section which generate a clock signal starting from the on / off switch of the operation manipulation section 8 being started and the operation of the dust collector 2 started. Counter unit 32 for counting the clock signal of (31) to measure the corresponding usage time each time the dust collector 2 is operated, and calculating the final cumulative usage time by adding the measured usage time to the cumulative usage time so far. A storage unit 33 for storing the final cumulative usage time of the counter 32, and comparing the final cumulative operating time with the proper usage time (life time) of the motor brush 3A or the filter 4, It may be configured to include a control unit 34 for controlling the operation state display device 20, such as outputting a signal for operating the display unit 40 when the last cumulative use time reaches the appropriate use time.

The display unit 40 informs the user that the motor brush 3A or the filter 4 has reached the end of its life, and for example, may use a lamp. Thus, the display unit 40 is preferably arranged together with the operation control unit 8 so that the user can observe it naturally while operating the on / off switch or the air volume control switch of the operation control unit 8 (see FIG. 3).

If the operation state of the centralized vacuum cleaner 1 to which the work handle 10 of the present invention is applied is sufficient to display only the motor brush 3A or the filter 4 in its operation state, the motor display unit 40A is sufficient. Although it is possible to comprise only one display unit 40 of the lamp) and the filter display unit 40B (lamp), it is preferable to provide both the motor display unit 40A and the filter display unit 40B. In the illustrated embodiment, although the lamp is illustrated as the display portion 40, a warning sound generator for generating a warning sound may be used as the display portion.

After replacing the motor brush 3A or the filter 4 which has reached the end of their life, it is necessary to delete and reset the accumulated use time stored for the motor brush 3A or the filter 4 used previously. Accordingly, the operation state display device 20 is provided with a reset switch unit 50 for deleting the stored cumulative use time. When the display portion 40 includes both the motor display portion 40A and the filter display portion 40B, the reset switch portion 50 is configured to separately reset them.

The work handle 10 of the present invention is attached to the central dust collection vacuum cleaner 1 so as to be detachably used, and thus the power supplied to the dust collector 2 is not permanently supplied. Therefore, the power supply to the operation state display device 20 is supplied by its own power supply 60, such as a battery.

In the use of the centralized vacuum cleaner 1, other unexpected emergency check situations may occur in addition to the case where the motor brush 3A or the filter 4 should be replaced at the end of their normal life.

For example, when the operation manipulator 8 of the work handle 10 is a wireless type, the on / off switch is turned on or cleaning is not performed without inserting the work handle 10 into the inlet 6 of the suction pipe 5. After finishing, it may cause a long time delay with the work handle 10 removed from the inlet 6 without turning the on / off switch off. On does not cause this). In this case, since the vacuum motor 3 is operated for a long time in the state in which the suction port 6 of the suction pipe 5 is closed, the vacuum motor 3 may be damaged due to overload.

For this reason, the central dust type vacuum cleaner 1 is generally equipped with stabilizers such as detecting by the sensor whether the rated current value supplied to the dust collector 2 exceeds the set current value and warning it. However, as described above, since the dust collector 2 is installed in a separate space such as a warehouse, a garage, a veranda, etc., which is isolated from the daily living space, the user often does not know the overload warning, and eventually the vacuum motor 3 It can be fatally damaged. Such an unexpected situation may occur in a wired method as well as a wireless method due to various reasons, and may also occur in the filter 4.

The work handle 10 of the present invention is operated by the display unit 40 by the abnormal operation signal of the vacuum motor 3 or the filter 4 transmitted from the dust collector 2 to the wired or wireless. It is desirable to inform the inspection of the filter 4. At this time, in order to distinguish whether the display state of the display unit 40 indicates the end of the life of the motor brush 3A or the filter 4 or indicates an abnormal abnormal operation, the display unit 40 indicating the replacement time and the inspection request are required. The display unit 40 may be formed separately, or the display method may be different for the same display unit 40. As an example of the latter display method, the lamp 40 is always turned on when the display unit 40 displays the replacement time, and the lamp blinks when the emergency check is displayed.

3 shows an example in which the display unit 40 performs the replacement display and the malfunction indication of the motor brush 3A or the filter 4 with one lamp, respectively, and the display unit 40A for the motor and the like. The filter display portion 40B is in one of an unlit state, a normally lit state, and a blinking state, respectively. When the user cleans using the work handle 10, the user sees the motor indicator 40A and the filter indicator 40B and checks whether the motor brush 3A and the filter 4 are normal or have to be replaced at the end of their service life. Or you can see immediately whether you need to check and take action immediately.

When the motor brush 3A or the filter 4 is replaced while the display unit 40 is in the constant lighting state, and the cumulative operating time is reset, the display unit 40 is turned off, and the operating time is newly counted and accumulated therefrom. When the display unit 40 is blinking and the motor brush 3A or the filter 4 is checked and an abnormal phenomenon is maintained, the display unit 40 turns off and the cumulative use time is accumulated over the previous use time. do.

According to the work handle 10 of the centralized vacuum cleaning apparatus according to the present invention described above, when using the centralized vacuum cleaning apparatus, the user of the vacuum motor (3) to the working handle 10 is always noticed and observed The operation state display device 20 is provided to display the replacement time and malfunction of the motor brush 3A and the filter 4, so that the user can see the display state of the operation state display device 20 to reach the end of its life. The motor brush 3A or filter 4 in an abnormal state can be replaced or inspected immediately. Therefore, the centralized vacuum cleaning can be performed by not replacing or checking the motor brush 3A or filter 4 at an appropriate time. It is possible to prevent as much as possible from shortening the life of the apparatus 1 or from failing to achieve an optimal cleaning effect.
