Technical field

The present invention relates to the technical field of air conditioners, in particular to an air conditioner indoor unit filter cleaning reminding system and method thereof and an air conditioner.

Background technique

At present, after the air conditioner has been used for a period of time, the filter of the indoor unit tends to collect a lot of dust and bacteria. If the filter of the air conditioner cannot be cleaned in time, the dust and bacteria inside are not good for human health, and it is not good for ventilation. Performance will also have an impact.

In summer, the air conditioner is used more frequently, so there will be more dust on the filter. Generally, before using the air conditioner in summer, the user will take out the filter and clean it once, but how many times is it appropriate to clean the filter during the summer? Or when the air conditioner is frequently used, is it enough to clean it every 10 or 15 days? Since the air conditioner is hung in a high place indoors, the way for users to check whether the filter needs to be cleaned is to stand at a high place and check the amount of dust on the filter, and then decide whether to clean it based on subjective judgment. It is a very inconvenient thing for elderly users with inflexible legs and feet to check the filter at a certain interval; even for young users, except for cleaning once before the summer, few people think of cleaning the filter frequently. network.

As shown in FIG. 1, in some optional embodiments, the air conditioner indoor unit filter cleaning reminder system includes;

The detection module 1, the detection module 1 is arranged in the housing of the air conditioner indoor unit, and is used to detect the amount of dust on the dust filter of the air conditioner indoor unit;

The judgment module 2 is connected to the detection module 1;

The reminder module 3, the judgment module 2 is connected to the reminder module 3. When the detection module 1 detects that the dust amount of the dust filter reaches a preset value, the judgment module 2 sends a signal to the reminder module 3 At this time, the reminding module 3 issues a cleaning warning.

In this embodiment, the detection module 1 judges whether the air conditioner indoor unit is running, and if so, the detection module 1 stops the detection; it should be noted that the detection module only performs detection when the air conditioner is not running. The detection data will not be affected by the air intake, the accuracy is high, and the detection module does not need to operate for a long time, and the detection module has a long service life; if not, the detection module 1 detects that the dust amount of the dust filter reaches the preset value At this time, the judgment module 2 sends a signal to the reminder module 3. At this time, the reminder module 3 issues a cleaning warning, which can conveniently and quickly determine whether the filter needs to be cleaned and the judgment result is in the form of voice or indicator light. Passed to the user to clean the filter, which can reduce the number of times the user has to check the filter at the heights, which brings convenience to the elderly with inflexible legs and feet, and can also avoid the inconvenience of the filter caused by the user's subjective judgment errors. The problem of timely or excessive cleaning frequency.

In some optional embodiments, further, the detection module 1 includes a weight detection device and an image detection device, the weight detection device is used to detect the weight of the dust filter, and the image detection device is used to collect the weight of the dust filter. Dust cover area, and the weight detection device and the image detection device are respectively connected to the judgment module 2, when the weight detection device detects that the weight of the dust filter is greater than or equal to a preset weight threshold, and/or, When the dust coverage area of the dust filter collected by the image detection device is greater than or equal to a preset dust coverage area threshold, the judgment module 2 sends a signal to the reminder module 3, and the reminder module 3 issues a cleaning warning.

In this embodiment, the weight detection device may adopt a weight sensor to weigh the dust filter. When the air conditioner stops working, the weight sensor starts to work, set the original weight of the dust filter to N, and set the threshold to 101%N, that is, when the weight display exceeds 101%N, it is determined that the dust filter needs to be cleaned; the image detection device also detects The other part of module 1 is carried out simultaneously with the weight detection.

Furthermore, the part of the dust filter directly below the air inlet grille of the cover is the first area, and the image detection device collects the dust coverage area of the first area.

The detailed description of image detection is as follows;

When the dust filter is inserted into the indoor unit of the air conditioner, it is C-shaped. In the dust filter part directly below the air inlet grille of the cover, there is a lot of dust, which is easier to cause dirty blocking problems. Set this area as the first area and set the dust filter. The area is S, and the area of the first region is set to 0.5S. The dust filter part facing the panel is relatively deep, so the dust accumulation speed is relatively slow. Image detection is used to collect the dust coverage area of the first area, for example, a dust area with a coverage area threshold of 30mm*30mm, when the number of dust areas greater than or equal to 30mm*30mm is collected in the image, more than 5 or more than 5 30mm* When the dust area is 30mm, that is, when the number of dust areas in the first area collected by the image is greater than or equal to 5, it is determined that the upper part of the dust filter is dirty at this time, and the user needs to clean it. Since the dust filter in the first area is facing the air inlet grille, when the dirty block area in the first area is large, it will have a great impact on the air volume, so you need to remind the user to clean the filter at this time.

When both the image detection and the weight detection meet any of the thresholds, it can be determined that the dust filter needs to be cleaned, and it can be flexibly determined whether the air conditioning filter has reached the cleaning time; by partitioning the dust filter, the camera device does not need to take the entire image For the dust condition of the filter, only part of the image needs to be collected. The amount of image collection is small and the judgment speed is fast. It is more suitable for current household air-conditioning equipment.

In some optional embodiments, further, the judgment module 2 is provided in the remote controller of the air conditioner indoor unit, and the judgment module 2 communicates with the detection module through an infrared transmission device provided on the cover. Module 1 is connected.

Furthermore, the judging module 2 includes a first judging unit and a second judging unit, the judging unit is used to judge whether the working state of the image detection device is normal, and if not, the display screen of the remote control flashes as an alarm Or display a fault code; the second judging unit is used to judge whether the weight detection device is working normally, and if not, flash an early warning or display a fault code on the display screen of the remote control.

The judgment module 2 is used to receive various detection data of the detection module 1, and analyze the detection data to obtain the judgment result. Both the weight threshold and the image threshold are pre-stored in the judgment module.

Optionally, the judging module 2 may be a controller, which may be installed in the remote controller or inside the casing of the internal machine.

The following takes the setting in the remote controller as an example; the judgment module 2 is divided into two judgment units, namely a first judgment unit and a second judgment unit. The judging module 2 is connected to the detecting module 1 through an infrared transmission device arranged on the housing; the first judging unit is used to judge whether the working state of the image detection device is normal, and if not, a warning flashes on the remote control display screen; The judging unit is used for judging whether the weight detection device is working normally, if not, flashing an early warning on the remote control display.

The reminding module 3 is an indicator light or a buzzer to remind the user to clean the filter. There are many ways to remind, which can be the indicator light set on the panel display module, which reminds the user through the flashing of the indicator light, or the buzzer, which reminds the user through the sound of the buzzer.

For example, taking the reminder device set in the remote controller as an example, if a buzzer is used, when the judgment module 2 obtains filter cleaning data, the reminder module 3 uses the buzzer to give a sound warning.

The air conditioner provided in the second aspect has the air conditioner indoor unit filter cleaning reminder system provided in the first aspect, and therefore has all the beneficial effects of the air conditioner indoor unit filter cleaning reminder system provided in the first aspect, and will not be repeated here.

In some optional embodiments, as shown in FIG. 1, the air conditioner indoor unit filter cleaning reminder method includes:

Step S1, the detection module 1 judges whether the air conditioner indoor unit is running, if so, the detection module 1 stops the detection; if not, the detection module 1 detects the weight and image of the dust filter;

Step S2: When the weight detection device detects that the weight of the dust filter is greater than or equal to a preset weight threshold, and/or when the dust coverage area of the dust filter collected by the image detection device is greater than or equal to a preset weight threshold When the dust coverage area threshold is reached, the judgment module 2 sends a signal to the reminder module 3, and the reminder module 3 issues a cleaning warning.

Specifically, for example, the weight detection device may adopt a weight sensor to weigh the dust filter. When the air conditioner stops working, the weight sensor starts to work, set the original weight of the dust filter to N, and set the threshold to 101%N, that is, when the weight display exceeds 101%N, it is determined that the dust filter needs to be cleaned; the image detection device also detects The other part of module 1 is carried out simultaneously with the weight detection.

In step S2, the dust filter part directly below the air inlet grille of the cover of the air conditioner indoor unit is taken as the first area, and the image detection device collects the dust coverage area of the first area, and when the image detects When the dust coverage area of the first area collected by the device is greater than or equal to the preset dust coverage area threshold, the judgment module 2 sends a signal to the reminder module 3, and the reminder module 3 issues a cleaning warning. Specifically, when the dust filter is inserted into the indoor unit of the air conditioner, it is C-shaped. In the dust filter part directly below the air inlet grille of the cover, there is a lot of dust, which is easier to cause the problem of dirt and blockage. Set this area as the first area. The area of the dust filter is set to S, and the area of the first area is set to 0.5S; the dust filter part facing the panel is relatively deep, so the dust accumulation speed is relatively slow. Image detection is used to collect the dust coverage area of the first area, and the coverage area threshold is 30mm*30mm dust area. When the number of dust areas greater than or equal to 30mm*30mm in the image collection exceeds 5 or more than 5 30mm*30mm dust areas In the dust area, that is, when the number of dust areas in the first area captured by the image is greater than or equal to 5, it is determined that the upper part of the dust filter is dirty and the user needs to clean; because the dust filter in the first area is facing In the air inlet grille, when the dirty and blocked area in the first area is large, it will have a great impact on the air volume, so you need to remind the user to clean the filter at this time; it should be noted here that the coverage area threshold can also be 20mm*20mm dust Area or 40mm*40mm dust area, the specific value is set according to actual needs and the size of the dust filter. Of course, according to the size of the set threshold, the number of judgments may not be 5, it can be 3 or 4 or 6, etc.;

In step S3, the dust filter is cleaned by the warning of the reminding module 3.

In summary, through the above reminding method, it is possible to quickly and conveniently determine whether the filter needs to be cleaned and transmit the judgment result to the user in the form of voice or indicator light. Through this filter cleaning reminder system, on the one hand, it can reduce users The number of times to check the filter screen on the heights brings convenience to the elderly with inflexible legs and feet; on the other hand, it can also avoid the problems of delayed cleaning of the filter screen or excessive cleaning frequency due to the user's subjective judgment error.
