Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention automatically adjusts the amount of waste air in a gas in correspondence with the amount of waste in the gas by adjusting the amount of air forcibly passing the gas through a filter in multiple stages. The present invention relates to a gas cleaning device that can be adjusted to a high degree.

[0002]

2. Description of the Related Art Generally, an air purifier using a filter is used to purify air in a room such as a living room, a reception room, and a conference room, and an unnecessary substance is removed from gas in a gas-filled container. Therefore, a gas cleaning device using a filter is used.

[0003] For example, in an air purifying apparatus, a filter is arranged on the back side (inside of the cabinet) of an intake port provided on a front panel of a cabinet, and a fan disposed behind the filter is driven by a motor, so that the air is removed from the intake port. The operation of exhausting the purified air by removing the waste such as dust and odor by passing the inhaled air through a filter and continuously exhausting the purified air to the outside is performed to clean the indoor air.

In a conventional air purifying apparatus, an automatic controller automatically controls the output of a drive motor of a fan based on a detection value of a dust sensor or an odor sensor provided in the air purifying apparatus, so that the amount of unnecessary matter is reduced. When the amount is small, the operation is performed by reducing the amount of air forcibly passing through the filter to a certain extent, and when the amount of waste is large, the operation is performed by increasing the amount of air forcibly passing through the filter to a certain degree.

[0005] In addition, the air purifier has an applicable floor area of 18 inches.
From large-sized air purifiers of so-called large air volume type of about tatami or less, to medium-sized air purifiers of so-called medium air-volume type with applied floor area of about 12 tatami or less, and furthermore, personal-type small-sized air purifier used by smokers for personal use Etc.

As shown in FIG. 15, there is a large air volume type large-sized air purifying apparatus which automatically operates the air volume (air purification processing capacity) in seven stages as shown in FIG. In such a large-sized air purifying apparatus, a model is used in which a large-sized air purifying apparatus is installed and used in a general 18-tatami room, and a microcomputer is operated by an operation mode switching program designed in advance based on experiments of this model. And automatically executes the operation mode in which the air volume is switched to seven stages.

For this reason, the average degree of dirt in the air in a general 18 tatami room is detected by a dust sensor or an odor sensor, and an appropriate air volume of a large-sized air cleaning device is logically or experimentally determined based on the detected value. The contents of the control operation as shown in FIG. 15 are set.

That is, when a sensor detection value of 10 that detects a predetermined minimum amount of dirt is detected from a sensor output value of 0 when the sensor of the large air cleaning device does not detect any dirt, The air volume of the air purifying device is set to silent 1.

Next, when the sensor detects a sensor detection value 12 of the next degree of contamination, which is slightly dirty, the air volume is set to silent 2.

Next, when the sensor detects the next sensor value 14 of the degree of dirt, the air volume is set to silent 3.

Next, when the sensor detects the next dirt degree sensor value 16, the air volume is set to a low value.

Next, when the sensor detects the next sensor value 18 of the degree of contamination, the airflow standard is set.

Next, when the sensor detects the next sensor value 20 of the degree of dirt, the airflow intensity is set.

Next, when the sensor detects the next sensor value 22 of the degree of contamination, the air volume is rapidly set.

In the above-described air purifying apparatus, the degree of air contamination in the room is detected by a sensor based on the above-described setting program, and the air volume is adjusted in seven stages from 1 to 7 based on the detected value. Operate automatically while switching.

[0016]

In the above-described conventional air purifying apparatus, the automatic operation program for switching the air flow in seven stages is based on an environment for purifying air in a general 18-tatami room. Is set. This may cause inconvenience when a large air purifier is used in a relatively small room such as 12 tatami mats, 8 tatami mats or 6 tatami mats, or when a smoker wants to use it personally to remove cigarette smoke. There is.

This is because when a large air purifier is used in a small room such as 6 tatami mats or 8 tatami mats, the large air purifier has a relatively high air purifying capacity per unit time, so that it is detected by a sensor. The degree of dirt will rapidly decrease. Along with this, in a large-sized air cleaning device, the air volume is switched at an early timing from the rapid to the silent 1 side.

In such a case, a user who uses this large-sized air purifying device indoors may notice that the wind noise of the motor or the fan changes stepwise each time the air volume of the large-sized air purifying device changes. It can be annoying to hear it often. Also, if a smoker uses a large air purifier to absorb tobacco smoke, the large air purifier will immediately respond to tobacco smoke and start operating at a rapid high air volume. There is a problem in that the wind noise of the motor and the fan becomes loud and the user may feel noise and feel uncomfortable.

In order to cope with such a situation, 6 tatami mats or 8 tatami mats are required.
Separately prepare and use dedicated air purifiers for small rooms such as tatami mats, and small personal type air purifiers used by smokers to collect cigarette smoke, or large air purifiers It is conceivable to operate the device manually each time, depending on its use. However, it is economically burdensome to prepare a plurality of different types of air purifying devices, and it is troublesome to manually operate a large-sized air purifying device each time it is in use. There is a problem that there is something that can not be troubled.

Also, an individual user may wish to purify room air as soon as possible. In such a case, it is more effective to set the operation of the air cleaning device to start from a weak or standard state, rather than performing a switching operation to gradually increase the air flow from the silent state 1. .

In consideration of the above facts, the present invention takes into account the environment in which the gas purifying device is used and the preferences and intentions of the user.
An object of the present invention is to newly provide a gas purifying apparatus capable of adjusting and controlling an air volume mode setting for automatic operation of the gas purifying apparatus.

[0022]

According to a first aspect of the present invention, there is provided a gas cleaning apparatus, comprising: a detecting means for detecting an amount of waste in a gas; and a detecting value of the detecting means being a predetermined detecting value. A controller that automatically sets and operates an air volume mode corresponding to a predetermined detection value from among air volume modes related to gas processing capacity set in a plurality of stages. And a setting means for setting a correspondence relationship between the detected value of the air flow rate and the air flow rate mode related to the gas processing capacity set in a plurality of stages.

According to a second aspect of the present invention, in the gas cleaning apparatus of the first aspect, the range from the lowest value to the highest value of the output of the detecting means is divided by the selected number of air volume modes, and the selected air volume mode is selected. And a control unit for setting an output value of the detection means operated by the control unit.

According to a third aspect of the present invention, in the gas cleaning apparatus of the first aspect, a plurality of air volume modes each set to a predetermined air volume and an air volume mode for selecting a plurality of air volume modes from the air volume modes. The air conditioner further includes a selection unit and a control unit that sets an output value of a detection unit that switches the air volume mode in accordance with a ratio of intervals of the air volume mode selected by the air volume mode selection unit.

With the above-described configuration, the user adjusts the air flow mode setting for automatic operation of the gas purifying apparatus in accordance with the environment in which the gas purifying apparatus is used and the preferences and intentions of the user. The desired air volume mode is set. Then, the gas purifier is automatically operated according to the set desired air volume mode, thereby improving the usability of the gas purifier.

[0026]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an air purifying apparatus according to the gas purifying apparatus of the present invention will be described with reference to the drawings.

As shown in the perspective view of the entire partial cross section of FIG. 1, the air purifying apparatus main body 30 is entirely formed in a rectangular parallelepiped shape with rounded corners, and has a wide front surface with a front panel 32 serving as an intake hole. To be configured.

An operation panel 34 is disposed near the front panel 32 on the upper flat portion of the air purifying device main body 30, and an exhaust hole 36 is disposed on a portion of the upper flat portion remote from the front panel 12.

A filter 38 is disposed inside the air purifying apparatus main body 30 at a position immediately behind the front panel 32 in parallel with the front panel 32.

In the air purifying apparatus main body 30, an exhaust port 36 is provided through a filter 38 from an intake port of the front panel.
And a fan driven by a motor (not shown) is arranged behind the filter 38.

The air purifying device main body 30 controls the rotation of the operating motor based on the command of the control device and adjusts the output of the fan operated by the operating motor, thereby removing the air sucked from the air inlet of the front panel 32. It is configured to control the amount of air that is purified through the filter 38 and discharged from the exhaust hole 36.

The control section of the air purifying apparatus main body 30 is disposed inside the air purifying apparatus main body, and is configured to be operated by each switch of the operation panel 34 and a remote controller.

This control unit has components for controlling the air flow as shown in FIG. This control unit has a CPU (central control unit) 40. The CPU 40 has a memory 42
And a display unit 46, a switch unit 48, a remote control receiving unit 50, a dirt sensor 52, and a drive control unit 54 are connected via an input / output interface 44. Although not shown, the CPU is provided with other necessary functional parts.

Next, the contents of the control operation of the control unit will be described with reference to the flowchart of FIG.

The control unit waits until the operation switch is turned on in step 100, and the operation switch is turned off.
When N operation is performed, the routine proceeds to step 102, where it is determined whether or not the operation mode is the automatic operation mode.

If the air volume is designated (manual mode), the operation proceeds to step 104 of another operation mode, and the operation manually instructed by the user is performed. When the processing of another operation mode is being performed in step 104, the control operation is also ended by the manual operation of the operation end by the user.

If it is determined in step 102 that the operation mode is the automatic operation mode, the flow advances to step 106 to determine whether or not the user has changed the program settings in the automatic operation.

If it is determined in step 106 that there is no program setting by the user in the automatic operation, the process proceeds to step 108 to perform the automatic operation in the normal mode. That is, in the case of the automatic operation, the normal mode operation processing (based on the detection value while detecting the degree of indoor air contamination by a sensor based on the setting program equivalent to the example illustrated in FIG. 15 described above). A process of automatically operating while switching the air flow in seven stages from 1 to 7) is executed.

The automatic operation in the normal mode in step 108 is performed until it is determined in the next step 112 that the user has instructed to change the program mode, or the user stops the operation in the next step 118. Continue until it is determined that a switch operation has been performed.

If it is determined in step 106 that the program has been set by the user in the automatic operation, the process proceeds to step 110, where the program mode is entered and the user designates the program according to the program mode designated by the user. Automatic operation is performed with the adjusted air volume.

The automatic operation in the program mode in step 111 is performed until it is determined in the next step 114 that the user has instructed to change the program mode, or in the next step 120, the user stops the operation. Continue until it is determined that a switch operation has been performed.

If it is determined in step 112 or 114 that the setting of the program mode is to be changed, the process proceeds to step 116 to perform a program mode setting process.

The program mode setting process in step 116 is performed by the user operating the operation unit to detect the value of the dirt sensor 52 for detecting the amount of waste in the gas contained in the air purifier main body 30. In response to the above, the operation is performed by setting the air volume mode related to the purification processing capacity set in a plurality of stages of the air cleaning device main body 30 to a desired air volume mode.

In this step 116, the CPU 40 sets a unique program mode by associating the detection range of the selected sensor and the selected air volume corresponding to the detection range with a predetermined correspondence relationship based on a command from the user, A process for storing this in the memory 42 is performed, and the process proceeds to step 110 described above.

If it is determined in step 118 or step 120 that the user has operated the switch to stop the operation, the process proceeds to step 122, and a predetermined time required for completing the operation of the air purifying apparatus main body 30 is determined. After performing the processing, the driving motor is stopped to stop the operation.

At this time, the last operation mode (normal mode or program mode) may be stored, and the operation may be started in this mode when restarting. Although it is omitted from the above flow chart,
At any time during the program mode operation, the mode can be shifted to the normal mode operation by a “normal mode return button” (not shown) or the like.

Next, an operation panel and a display section of an operation panel or a remote controller for executing a procedure for setting a program mode will be described with reference to FIGS. 4 and 5. FIG.

As shown in FIG. 4, the operation unit 72 includes a power switch 74, an automatic operation switch 76, and a silent 1 switch 7.

4 and a clear switch 96.

As shown in FIG. 5, the display section 97 includes a display 98 for silent 1, a display 100 for silent 2, a display 102 for silent 3,
Weak display 104, standard display 106, strong display 108,
