Description

{Method for controlling of robot purifier using heat sensing}

The present invention relates to a method of controlling a robot purifier, and more specifically, to a method of controlling a robot purifier that can detect a user's heat and provide various convenience functions.

Robot cleaners, in which robots capable of autonomous driving perform the cleaning function, are widely used. In addition, a robot purifier, in which an autonomous robot performs the function of air purification, has also been continuously developed since Korean Utility Model No. 20-0333880.

Unlike robot vacuum cleaners, robot purifiers do not need to travel across all floor surfaces in the space being used, but instead drive to one point within a unit space (for example, a room, kitchen, living room, etc. in a typical home) and clean the space. If it is determined that air purification is necessary, perform air purification.

Air purification is implemented by inhaling low-quality air and then discharging high-quality air by filtering it. Suction and discharge use a fan inside the purifier.

It is similar to an electric fan in that it uses a fan to discharge air. Using this, an air purifying fan that combines the air purifying function, which is the function of an air purifier, and the fan function of reducing temperature by discharging strong wind is a technology already known in the prior art.

However, this control method for an air purifying fan is only a control method for a fixed fan or a fixed air purifier. In other words, like a fan or air purifier, it only operates under certain conditions in a state where it cannot be moved.

The present invention seeks to provide a method of controlling a robot purifier that provides excellent comfort to users and adds health management functions by using both the running performance of the robot purifier and the temperature reduction performance due to air discharge by the fan.

(Patent Document 4) KR 10-2011-0048384

The present invention was created to solve the above problems.

Specifically, by using the unique driving performance of the robot purifier and the temperature reduction performance by the fan, we provide a robot purifier control method that can automatically provide excellent thermal comfort to the user at the appropriate time, like a fan capable of autonomous driving. I want to.

One embodiment of the present invention to solve the above problems includes (a) detecting body temperature by a body temperature sensing means of the robot purifier; and (b) when the detected body temperature is above the reference value, the operation setting module 534 of the control unit 500 of the robot purifier causes the robot purifier to move toward the direction in which the body temperature was detected and operate, thereby providing purified air. A method of controlling a robot purifier including the step of discharging is provided.

In addition, in step (b), (b1) when the detected body temperature is above the reference value, the operation setting module 534 moves the cleaning unit 100 of the robot purifier in the direction where the body temperature was detected. It is preferable to further include a step of rotating toward and discharging the purified air.

In addition, before step (a), (a1) the robot purifier docked in the docking unit 300 undocks at a predetermined time period and moves to predetermined unit spaces to detect body temperature. It is desirable to include more.

In addition, before step (a1), it is preferable to further include the step (a2) of inputting the predetermined time period and the predetermined unit spaces through the terminal T.

Additionally, (c) detecting the indoor temperature by the temperature sensing means 531 of the robot purifier; and (d) when the detected indoor temperature is equal to or higher than the indoor temperature reference value, the operation setting module 534 of the control unit 500 of the robot purifier further performs a step of discharging purified air by causing the robot purifier to operate to purify the air. It is desirable to include it.

In addition, it is preferable that the body temperature sensing means is an infrared camera 216 provided in the robot purifier.

In addition, after step (b), (c) when the detected body temperature is higher than the upper warning limit, the transceiver unit 535 of the control unit 500 of the robot purifier communicates with the preset emergency contact information through the terminal T. It is desirable to further include a step of outputting a preset warning.

In addition, after step (b), (c) when the detected body temperature is below the lower warning value, the transceiver unit 535 of the control unit 500 of the robot purifier communicates to a preset emergency contact number through the terminal T. It is desirable to further include a step of outputting a preset warning.

According to the present invention, even while the user is asleep at night when the tropical night phenomenon occurs, the robot purifier can automatically move to the user with a high body temperature and provide cool breeze. It can help with good sleep and health.

Even in spaces where multiple users live (for example, a family of four), body temperature can be measured and managed periodically as the users move from room to room where they sleep.

Since the indoor temperature can be checked, it is also possible to perform the function of lowering the overall indoor temperature.

In addition, if the body temperature is abnormally high or abnormally low, a warning can be notified to disaster prevention agencies, close neighbors, or family members. If a health problem is identified for a user living alone, the system can automatically prepare for it. In particular, it is effective because it allows the elderly to check for health problems from the outside.

The guide fan assembly 120 is a part that purifies the air.

The fan 121 of the guide fan assembly 120 receives power from a power member (not shown) and rotates, sucks air from both sides to be filtered, and discharges the filtered air through the discharge grill 129. .

The portion where the discharge grill 129 is located constitutes the front of the robot purifier. That is, the filtered air is discharged from the front of the robot purifier according to the present invention. Of course, it is also possible to have the discharge grill 129, which is an air discharge port, located at the top or rear rather than the front.

The parts where air is sucked are on both the left and right sides, and each consists of a guide fan 122, an air cleaning filter 123, and a cover filter 124.

The cover filter 124 is a component exposed on the outside of the purifier 100 and is provided with a number of fine holes to primarily filter the inhaled air and at the same time protect the air purifier filter 123.

The air cleaning filter 123 is a core component that filters sucked air and may include any conventionally known filter. For example, deodorizing filters, HEPA filters, etc. may be included here.

The guide fan 122 guides the air that has passed through the air cleaning filter 123 to the inside.

The driving unit 200 supports the cleaning unit 100, performs an autonomous driving function according to conditions, and is docked with the docking unit 300 to receive power.

A body 210 is provided outside the traveling unit 200. The body 210 protects the battery, board, camera, power member, and various sensors mounted inside.

The display unit 211 is located on the front of the body 210. The display unit 211 outputs various information such as charging status, filter status, and use mode.

A camera 216 is located on the rear of the body 210. The camera 216 may be an infrared camera for body temperature detection, which will be described later.

A ball bearing 221, a gear 222, an LED board 223, and a board cover 224 are provided inside the running part 200, and are connected to the cleaning part 100 by a connector 225. do.

The cleaning unit 100 can be rotated on the traveling unit 200 by the ball bearing 221 and the gear 222.

The gears of the gear 222 can rotate by being connected to another gear (not shown) of a power member (not shown) inside the traveling unit 200. The inner unevenness of the gear 222 is connected to the outer unevenness of the gear head 113 described above, thereby rotating the cleaning unit 100.

A plurality of LEDs are located radially on the LED substrate 223.

A substrate cover 224 is placed on top of the LED substrate 223 to protect it. A reed switch (not shown) is provided on one side of the substrate cover 224. A magnet is located in the gear 222, and the correct position can be confirmed using a reed switch (not shown). It is also possible to check the correct position using a micro switch or optical sensor.

The connector 225 is a part that protrudes toward the cleaning unit 100 when the cleaning unit 100 and the traveling unit 200 are coupled and passes through the gear head 113. A slip ring wire (not shown) is provided inside the connector 225 to prevent the cable connecting the traveling unit 200 and the cleaning unit 100 from being twisted even when the cleaning unit 100 rotates 360 degrees. Alternatively, you can prevent twisting of the cable by setting it to repeat forward and reverse rotation without a slip ring wire.

In this way, not only is the cleaning unit 100 and the traveling unit 200 connected by the connector 225, but it also prevents the cleaning unit 100 and the traveling unit 200 from being separated or separated even when turning left and right and up and down, and The center of government (100) is maintained.

A base 230 is located on the lower surface of the traveling unit 200.

The base 230 is equipped with a main wheel 231 that moves the traveling unit 200 by electrical signals from the driving unit 250 and an auxiliary wheel 232 that assists the driving unit 200.

A separate direction change member (not shown) may be further connected to either the main wheel 231 or the auxiliary wheel 232 to change the direction of movement of the robot purifier.

The driving unit 250, which is not shown in FIGS. 1 to 4, receives power from a charged battery (not shown) and transmits power to the main wheel 231.

The base 230 is provided with a docking groove 233 into which the docking portion 300 can be inserted, and a main body connection terminal 238 is provided within the docking groove 233. The main body connection terminal 238 may be connected to the docking connection terminal 308 of the docking unit 300.

The docking home 233 is formed to face the rear of the robot purifier.

The docking unit 300 receives power from the outside through a wire, and supplies power to a battery (not shown) in the traveling unit 200 through the docking connection terminal 308.

A sensor may be provided in either the docking unit 300 or the traveling unit 200 and an identifier may be provided in the other. Through this, the distance between the docking unit 300 and the robot purifier can be confirmed.

The control unit 500 will be described with reference to FIG. 5 .

The control unit 500 includes a temperature detection means 531 such as a sensor that detects the room temperature, a body temperature detection module 533 capable of detecting the user's body temperature in connection with a separate body temperature detection means (not shown), and operation settings. It includes a module 534 and a transceiver 535 capable of transmitting and receiving information with the user's terminal (T).

The body temperature sensing means may be any means that can detect the user's body temperature remotely from the robot purifier. As mentioned above, in one example this may be an infrared camera 216.

The body temperature detection module 533 checks the body temperature detected by a body temperature detection means such as the infrared camera 216.

The operation setting module 534 is linked with the temperature detection means 531 and the body temperature detection module 533 to move the robot purifier, rotate the purifier 100, and operate air purification. For this purpose, it may be linked to the driving unit 250 of the traveling unit 200.

Additionally, information can be transmitted and received with the user's terminal (T) using a separate transmitting and receiving unit 535.

Description of heat detection and robot purifier control method using it

The robot purifier control method according to the present invention will be described starting from the state where the robot purifier is docked in the docking unit 300.

The robot purifier can undock and move to predetermined unit spaces at a predetermined time period, even without a separate movement signal.

At night, when the tropical night phenomenon occurs, this function is especially effective, allowing the device to detect body temperature while moving from room to room, even while multiple users are asleep.

The predetermined time period and predetermined unit spaces may be input by the user through the terminal T, and may be predetermined as initial values.

When the robot purifier moves to a specific unit space, it detects body temperature while rotating 360 degrees using a body temperature detection means such as an infrared camera 216.

If the sensed body temperature is within the normal range (e.g., 36 to 37 degrees Celsius), there is no need to function separately.

However, if the detected body temperature is above the reference value (e.g., 37 degrees Celsius), it is determined that the user's body temperature is somewhat high, and air is discharged toward the user. For example, at night in the summer when the tropical night phenomenon occurs, it can provide a cool feeling to the user and at the same time performs an air purification function.

Specifically, if the detected body temperature is higher than the reference value, the operation setting module 534 of the control unit 500 of the robot purifier causes the robot purifier to move toward the direction in which the body temperature was detected.

Next, the purifier 100 of the robot purifier is rotated toward the direction in which body temperature is detected, and then the fan 121 is operated to discharge the purified air toward the user.

Even during discharge, the body temperature sensing means periodically detects the body temperature, and when the body temperature falls below a reference value (for example, 37 degrees Celsius), the operation of the fan 121 is stopped.

In one embodiment of the present invention, when the detected body temperature is above the upper warning value (e.g., 39 degrees Celsius), the transceiver 535 communicates to a preset emergency contact through the terminal T and sends a preset warning. You can also print it out.

Conversely, even if the detected body temperature is below the lower warning limit (e.g., 35 degrees Celsius), the transceiver 535 may output a preset warning by communicating with a preset emergency contact number through the terminal T.

Emergency contact information may be a disaster prevention organization such as a fire department or hospital, or a contact information of a family member located nearby, and the printing method may be any method such as text or phone call.

Through this, it can also perform the function of managing the health of users who live alone and warning others of danger.

In another embodiment of the present invention, the indoor temperature is detected by the temperature sensing means 531, and when the detected indoor temperature is above the indoor temperature reference value (for example, 26 degrees Celsius), the robot purifier is operated to purify the air. By doing so, purified air can also be discharged.

In this case, the overall indoor temperature of the unit space can be reduced.

Above, the present invention has been described with reference to the embodiments shown in the drawings so that those skilled in the art can easily understand and reproduce the present invention. However, these are merely illustrative examples, and various modifications and equivalent alternatives can be made by those skilled in the art from the embodiments of the present invention. It will be appreciated that embodiments are possible. Therefore, the scope of protection of the present invention should be determined by the scope of the patent claims.
