Description

Combination of vacuum cleaner and remote control

This application claims the priority of the Chinese patent application with application number 202010812575.9 filed with the China Patent Office on August 13, 2020, the entire contents of which are incorporated herein by reference.

technical field

The present application relates to a combination of a vacuum cleaner and a remote control, and in particular, to the code matching between the vacuum cleaner and the remote control.

Background technique

In order to realize the control of the vacuum cleaner at a certain distance from the vacuum cleaner, the vacuum cleaner is equipped with a remote control in the related art. The Chinese patent CN201295199 filed on October 23, 2008 discloses a vacuum cleaner with a remote control, which can remotely control the fan of the vacuum cleaner ( The motor is turned on and off, and the fan provides the power to suck the garbage. The main switch of the vacuum cleaner has three gears, which are closed, open, and remote. When the switch is in the off position, the vacuum cleaner is in the off state; When it is in the open position, the vacuum cleaner is in an open state; when the switch is in the remote control position, the fan of the vacuum cleaner can be remotely turned on and off through the remote control. In the related art, the vacuum cleaner and the remote control usually need to be paired successfully before the vacuum cleaner can be remotely controlled by the remote control, otherwise the remote control cannot control the vacuum cleaner; The controller and the wireless communication module can be two chips, or they can be integrated into one chip. The antenna is used to receive the signal from the remote control, and the wireless communication module is used to process (such as amplify, demodulate, and shape) the signal of the antenna. The controller sends a control signal based on the signal transmitted by the wireless communication module to control the operation of the fan (for example, control the opening, closing, speed regulation of the fan, etc.); If the remote control is successfully paired, it is necessary to set up the relevant assembly structure to install the indicator light or buzzer. For example, for the indicator light, you need to open a hole in the vacuum cleaner case to place the indicator light, and set the circuit carrying the indicator light inside the case. The board, indicator light or buzzer itself and its assembly structure will lead to an increase in manufacturing difficulty and cost; and neither indicator light or buzzer can intuitively and accurately convey the indication of successful code matching to the user, and the user tends to ignore the indicator light or the buzzer. The indication of the buzzer leads to the fact that the code has been successfully matched, but the user does not know it and continues to perform the code match. Even if the user pays attention to the indication of the indicator light or the buzzer, it is inevitable that they will doubt whether the code is really successful.

The main switch 15 is partially exposed to the outside of the machine head housing 13. The main switch 15 can be a conventional rocker-type rocker switch. The main switch 15 has three gears, which correspond to the opening, closing, and remote control of the vacuum cleaner. state; when the main switch 15 is in the first gear, the vacuum cleaner is turned off, and the fan 10 does not work at this time, and cannot be turned on remotely; when the main switch 15 is in the second gear, the vacuum cleaner 10 is turned on, and the fan 10 is running normally. , but cannot be remotely controlled by the remote control; when the main switch 15 is in the third gear, the vacuum cleaner is in the remote control mode, and the vacuum cleaner can be remotely controlled by the remote control only when the vacuum cleaner is in the remote control mode, and the vacuum cleaner is in the remote control mode. The way that the vacuum cleaner switches to the remote control mode is not limited to the third gear of the main switch 15 in this embodiment. For example, a dedicated remote control button (such as a push button) can also be set on the vacuum cleaner 10. The vacuum cleaner 10 switches to the remote control mode.

The premise that the remote control can remotely control the startup and shutdown of the vacuum cleaner is that the remote control and the vacuum cleaner have been successfully paired. , so that the remote control cannot remotely control the vacuum cleaner; if the code matching between the remote control and the vacuum cleaner is successful, the remote control can be controlled normally without re-coding the remote control; in this embodiment, if the vacuum cleaner 10 is not in the remote control mode, the first wireless communication module 21, The first controller 20 is not connected to the power supply. Of course, the vacuum cleaner cannot be remotely controlled at this time, nor can the code be paired; when the vacuum cleaner 10 is in the remote control mode, the first wireless communication module 21 and the first controller 20 are powered on, so that the vacuum cleaner 10 can be powered on. It communicates wirelessly with the remote control, so it can be paired and remotely controlled (provided that the pairing is successful).

10 , the second controller 30 is provided with a first pin 300 and a second pin 301 , the first pin 300 is grounded through the code matching switch 34 , the second pin 301 is grounded through the remote control switch 35 , and the code matching switch 34 can be a push-button switch. When the code is matched, the code-matching switch 34 is triggered by pressing the code-matching switch 34. After the code-matching switch 34 is triggered and connected, the potential of the first pin 300 is pulled down, and the second controller 30 is based on the first pin. The low-level signal of 300 enters the code matching state, and the second controller 30 communicates with the vacuum cleaner wirelessly through the second wireless communication module 31 and the second antenna 32 to complete the code matching work. When the main switch 15 is in the remote control gear or the vacuum cleaner is in the remote control mode, the vacuum cleaner can be remotely controlled; during remote control, press the remote control switch 35 once, and the fan 10 starts to run normally after power-on, and press the remote control switch 35 again to turn off the fan 10, that is, Each time the remote control switch 35 is pressed, the vacuum cleaner or the fan 10 switches a state (switches between on and off). Specifically, when the fan 10 is in the off state, the remote control switch 35 is pressed once, the remote control switch 35 is triggered and connected, and the potential of the second pin 301 is pulled down, and the second controller 30 recognizes the low potential signal of the second pin 301. Send a command to the vacuum cleaner through the second wireless communication module 31 and the second antenna 32, the remote control fan 10 changes state (switches from the off state to the on state), and presses the remote control switch 35 again, so that the potential of the second pin 301 is pulled again. Low, the second controller 30 recognizes the low potential signal of the second pin 301 and sends a command to the vacuum cleaner through the second wireless communication module 31 and the second antenna 32, and the remote control fan 10 changes state again (switches from the on state to the off state ).

If the code matching between the remote control and the vacuum cleaner is successful, the fan 10 is automatically powered on and running (that is, the fan 10 is automatically turned on), to remind the user that the code matching between the vacuum cleaner and the remote control is successful; if the code matching between the vacuum cleaner and the remote control is successful, the fan 10 is automatically powered on and running After the first time, it is automatically turned off; the so-called automatic means that no user intervention is required. After the code is successfully matched, the first controller 20 executes the predetermined program code to start the fan 10 spontaneously, and automatically shuts down after the first time. Fan 10. Through the automatic power-on operation of the fan 10, the user is prompted that the code pairing is successful, and the user does not need to perform additional operations (such as triggering the remote control switch of the remote control, etc.) (meaning that the vacuum cleaner and its fan can be used), and then the code matching action can be stopped in time; compared with the lighting of the indicator lights or the sound of the buzzer in the related art, the automatic start of the fan 10 has a better indication effect on the success of the code matching. In order to be clear and extremely difficult to ignore; compared with the related art, the present application basically does not need to add special indicating elements (such as indicator lights or buzzers) to the vacuum cleaner, and basically does not need to change the mechanical structure of the vacuum cleaner itself (required in the related art). The mechanical structure of the vacuum cleaner itself is changed to configure the indicator light or buzzer), and the automatic start of the control fan 10 after the code is successfully matched can basically be realized by program code control, so that the cost is lower. The first time is between 0.2 seconds and 10 seconds, and optionally, the first time is between 0.3 seconds and 3 seconds, for example, 0.5 seconds, 1 second, 1.5 seconds, 2 seconds, 2.5 seconds.

Since the automatic startup of the fan 10 after the successful code matching prompts the user that the code matching is successful, the user can release the code matching switch 34 after receiving the aforementioned prompt. After the code matching between the vacuum cleaner and the remote controller is successful, the user can remotely control the fan 10 through the remote control switch. The user can choose to remotely turn off the fan 10 through the remote control within the first time when the fan 10 is automatically powered on and running, so that the fan 10 does not complete the first time. The power-on operation of the fan 10 is turned off in advance; of course, without remote control, the fan 10 will be automatically turned off after the first operation. It can also be set that the fan 10 is not controlled by the remote controller during the first time when the fan 10 is automatically powered on.

The first controller 20 will store the identification information of the remote control, etc. The fan 10 is under the control of the first controller 20, automatically powered on and runs and automatically shuts down after the first time, the first controller 20 after the code is successfully matched A control signal will be sent to make the fan 10 power on and run, and after the first time, the first controller 20 controls the fan 10 to turn off. Only when the vacuum cleaner is connected to the power supply and switched to the remote control mode can the remote control work remotely; the process of remote control of the vacuum cleaner is roughly as follows: triggering the remote control switch 35 , based on the triggering of the remote control switch 35 , the second controller 30 issues an instruction, and the second wireless communication module 31 After the above-mentioned command is processed, it is sent by the second antenna 32. The first antenna 22 receives the signal sent by the second antenna 32 and transmits it to the first wireless communication module 21. After processing, the first wireless communication module 21 transmits it to the first controller 20. , the first controller 20 outputs a control signal to cause the fan 10 to switch states (the fan 10 in the power-off and off state is powered on or the fan 10 in the power-on running state is powered off and off). The first controller 20 outputs the output through the drive pin 200 The aforementioned control signal controls the power-on (on) and power-off (off) of the fan 10 through the electronic switches Q1, Q2, and Q3. The specific circuit refers to FIG. 11; every time the remote control switch 35 is triggered, the fan 10 will be in a state Specifically, each time the remote control switch 35 is triggered, the fan 10 will switch between the power-on running state and the power-off shutdown state.

The wireless signal transmission power of the remote control when remotely controlling the vacuum cleaner is greater than the wireless signal transmitting power when the remote control is paired with the vacuum cleaner, and the wireless signal receiving power when the vacuum cleaner accepts the remote control is greater than the wireless signal when the vacuum cleaner is paired with the remote control Received power, because when the code is paired, not only the wireless signal transmission power of the remote control is smaller than that of the remote control, but also the wireless signal receiving power of the vacuum cleaner is smaller than that of the remote control, so that the code distance and the remote control distance can be significantly increased. Open the gap to obtain a significantly shorter pairing distance than the remote control distance.

The wireless signal transmission power of the remote control includes the first transmission power and the second transmission power, the first transmission power is greater than the second transmission power, and the wireless signal reception power of the vacuum cleaner includes the first reception power and the second reception power, and the first reception power is greater than For the second receiving power, the code matching switch 34 is released at any time after the vacuum cleaner and the remote control are successfully matched, the wireless signal transmission power of the remote control is restored from the second transmission power to the first transmission power, and the wireless signal receiving power of the vacuum cleaner is changed from the second transmission power to the first transmission power. The received power is restored to the first received power. In this way, both the vacuum cleaner and the remote control can restore a larger wireless communication power (the first received power and the first received power) after the code is successfully matched, so that the relatively short The code-matching distance is restored to a relatively long remote control distance, so that long-distance remote control can be performed. When the fan 10 is in the state of power-on operation (power-on operation is the live operation of the fan 10 under the electric drive, excluding the rotation of the fan 10 under the action of inertia or the action of the external airflow after the power failure), then the code switch 34 It is invalid for the vacuum cleaner (the so-called invalid means that the vacuum cleaner does not respond to the matching code signal of the remote control or the first controller 20 does not respond to the matching code signal of the remote control, the vacuum cleaner or the first controller 20 regards the matching code signal as invalid exists), therefore, since the fan 10 will be automatically powered on and run for the first time after the code is successfully matched, the code-matching switch 34 is invalid for the vacuum cleaner within the first time, resulting in that if the code is not released within the first time When the switch 34 is turned on, the vacuum cleaner still receives the code signal at the second received power but does not respond to the code signal.

The wireless signal transmitting power when the remote controller remotely controls the vacuum cleaner adopts the first transmitting power, and the wireless signal receiving power when the vacuum cleaner accepts the remote control by the remote controller adopts the first receiving power. The code matching process of the vacuum cleaner and the remote control is as follows:

The vacuum cleaner switches to remote control mode;

Trigger the code pair switch 34;

The wireless signal transmission power of the remote control is reduced from the first transmission power to the second transmission power;

The wireless signal receiving power of the vacuum cleaner is reduced from the first receiving power to the second receiving power;

The remote controller whose wireless signal transmission power is the second transmission power and the vacuum cleaner whose wireless signal reception power is the second reception power continue to perform code pairing until the code matching is successful.

The remote controller whose wireless signal transmission power is the second transmission power means that the remote controller uses the second transmission power at this time, and the vacuum cleaner whose wireless signal receiving power is the second reception power means that the vacuum cleaner uses the second reception power at this time. After triggering the pairing switch 34, it is necessary to keep pressing the pairing switch 34, so that the pairing switch 34 is kept in the triggered state, so that the remote control continues to send the pairing command. If the pairing switch 34 is released in advance, the pairing fails; the second control The controller 30 reduces the wireless signal transmission power of the remote control from the first transmission power to the second transmission power based on the triggering of the code matching switch 34; The signal transmission power is restored from the second transmission power to the first transmission power; the first controller 20 reduces the wireless signal reception power of the vacuum cleaner from the first reception power to the second reception power based on the code matching instruction of the remote controller; When the switch 34 is released from the trigger state, the remote control will no longer send the code matching instruction to the vacuum cleaner, and the first controller 20 restores the wireless signal receiving power of the vacuum cleaner to the first receiving power; specifically, once the code matching switch 34 is released In the trigger state, the received power of the wireless signal of the vacuum cleaner is restored from the second received power to the first received power. The matching between the vacuum cleaner and the remote control takes about 3 seconds, that is, the matching switch 34 needs to be kept in the activated state for about 3 seconds, after which the matching switch 34 can be released.

The code-matching switch 34 can be a push-type switch. Press the code-matching switch 34 to trigger the code-matching switch 34, and release the code-matching switch 34 to make the code-matching switch 34 exit the trigger state; the wireless signal transmission power of the remote control can be controlled by the second The wireless signal transmission power of the wireless communication module 31 is represented, and the size of the wireless signal transmission power of the remote controller can be realized by changing the power parameter of the second wireless communication module 31; specifically, when the code switch 34 is triggered, the second control The controller 30 sends an instruction code to the second wireless communication module 31 based on the triggering of the code switch 34 to change the power parameters of the second wireless communication module 31, thereby changing the wireless signal transmission power of the remote control; the wireless signal transmission power of the vacuum cleaner It can be represented by the wireless signal receiving power of the first wireless communication module 21, and the size of the wireless signal receiving power of the vacuum cleaner can be realized by changing the power parameters of the first wireless communication module 21; After the code command, the first controller 20 sends the command code to the first wireless communication module 21 to change the power parameter of the first wireless communication module 21, thereby changing the wireless signal receiving power of the vacuum cleaner; since the first controller 20 needs to use the The first antenna 22 and the first controller 20 are used to receive the code-matching instruction, so within a very short time (for example, within 100 microseconds) after the code-matching switch 34 is triggered, the wireless signal transmission when the vacuum cleaner receives the code-matching instruction from the remote control The power is still the first received power, and the first controller 20 can finish reducing the wireless signal received power of the vacuum cleaner to the second received power after a very short period of time (for example, 100 microseconds) at the beginning. 2. Receive power to receive the code pairing instruction from the remote control.

The wireless signal transmission power and the wireless signal reception power determine the effective wireless communication distance or the maximum wireless communication distance of the wireless signal. In this embodiment, the second transmission power is the minimum wireless signal transmission power of the remote controller, and the second reception power It is the minimum wireless signal receiving power of the vacuum cleaner. It is designed so that the maximum wireless communication distance between the vacuum cleaner and the remote control is minimized as much as possible during code matching, so that the maximum code-matching distance between the vacuum cleaner and the remote control is the largest. The limit is as small as possible less than the maximum remote control distance between the vacuum cleaner and the remote control, so as to achieve a prominent short-distance code matching effect. The first transmitting power is the maximum wireless signal transmitting power of the remote control, and the first receiving power is the maximum wireless signal receiving power of the vacuum cleaner. In this way, the previous effect (making the maximum distance between the vacuum cleaner and the remote control during code matching) On the basis of minimizing the wireless communication distance as much as possible), the maximum wireless communication distance between the vacuum cleaner and the remote control during remote control is maximized, so that the gap between the code distance and the remote control distance can be opened as large as possible to achieve The outstanding combined effect of short-distance code matching and long-distance remote control, in one embodiment, the maximum code-matching distance between the vacuum cleaner and the remote control is 2.5 meters, and the maximum remote control distance between the vacuum cleaner and the remote control is 20 meters.

In the process of matching the code between the vacuum cleaner and the remote controller, it is necessary to keep pressing the matching switch 34 until the matching is successful. If the matching switch 34 is released before the matching between the vacuum cleaner and the remote controller is successful, the matching fails. Keeping pressing the pairing switch 34 for a long time is to keep the pairing switch 34 in a triggered state. In this embodiment, the pairing switch 34 is in a triggered state so that the potential of the first pin 300 is pulled down.

At any time after the wireless signal transmission power of the remote control is reduced from the first transmission power to the second transmission power, release the matching switch 34, and the wireless signal transmission power of the remote control returns to the first transmission power; Release the matching switch 34 at any time after the wireless signal transmission power of the remote controller is reduced from the first transmission power to the second transmission power, and the wireless signal transmission power of the remote control is restored from the second transmission power to the first transmission power. After the code matching switch 34 is released, the second controller 30 sends an instruction to the second wireless communication module 31, so that the power parameter of the second wireless communication module 31 is changed from the parameter value corresponding to the second transmission power to the parameter value corresponding to the first transmission power. parameter value, so as to adjust the wireless signal transmission power of the remote control to the first transmission power.

The code matching process in this embodiment is completed based on program codes. The program code of the vacuum cleaner can be stored in the first controller 20, and the program code of the remote control can be stored in the second controller 30. The preparation of program code is a conventional programming skill, so it is unnecessary to repeat it.
