In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The first embodiment is as follows:
referring to fig. 1, a schematic structural diagram of a water level monitoring device according to an embodiment of the present invention is shown. The water level monitoring device includes, for example: a water receiving tray 210, a first monitoring electrode 13a and a second monitoring electrode 13 b. The first monitoring electrode 13a and the second monitoring electrode 13b are suspended in the water receiving tray 210, and the bottom of the water receiving tray 210 is further provided with a loop electrode 19.
In an embodiment, when the water level of the condensed water collected in the water pan 210 reaches a preset warning water level, the first monitoring electrode 13a and/or the second monitoring electrode 13b is electrically connected to the return electrode 19, and is processed in the controller of the air conditioner to form a warning signal.
Further, the first monitoring electrode 13a and the second monitoring electrode 13b are respectively disposed on the left and right sides of the water pan 210 and are disposed in a suspending manner, that is, a certain distance is preset between the first monitoring electrode 13a and the second monitoring electrode 13b and the inner side wall of the water pan 210, so as to prevent condensed water from being hung on the wall to the inner wall of the water pan 210 and being respectively attached to the first monitoring electrode 13a and the second monitoring electrode 13b, and further, a controller of the air conditioner indoor unit 200 sends out early warning misjudgment.
Preferably, the return electrode 19 is disposed at the bottom center of the water receiving tray 210, that is, the distance between the return electrode 19 and the first monitoring electrode 13a is equal to the distance between the return electrode 19 and the second monitoring electrode 13b, so as to reduce a large error in the electrical signal received by the controller due to the difference in the distances between the return electrode 19 and the first monitoring electrode 13 a.
Further, the return electrode 19 includes a first return electrode and a second return electrode, the first return electrode is disposed right under the first monitoring electrode 13a, and the second return electrode is disposed right under the second monitoring electrode.
Specifically, the distance between the first loop electrode and the first monitoring electrode 13a in the vertical direction is L1The distance between the second loop electrode and the second monitoring electrode 13b in the vertical direction is L2Wherein L is1And L2Are equal.
Referring to fig. 2, which is a schematic diagram of a first circuit structure 110 of the water level monitoring device provided by the present invention, the schematic diagram of the first circuit structure 110 will be described in detail.
The first circuit configuration 110 includes, for example, the first monitoring module 10 and the controller 20, which are electrically connected.
Specifically, the first monitoring module 10 includes, for example, a sampling circuit and a monitoring circuit. The sampling circuit is provided with a voltage access end 11, a first grounding end 12 and a sampling end 15 positioned between the voltage access end and the first grounding end; the monitoring circuit is electrically connected to the voltage input terminal 11 and is provided with a second grounding terminal 14, and a monitoring terminal 16 is arranged between the voltage input terminal 11 and the second grounding terminal 14; a voltage dividing resistor 18 and a first monitoring electrode 13 are arranged between the monitoring terminal 16 and the second grounding terminal 14. Wherein the sampling terminal 15 is in the same position of the first circuit configuration 110 as the monitoring terminal 16.
The controller 20 is provided with an electrical signal receiving terminal and electrically connects the sampling terminal 15 and the monitoring terminal 16. For example, the controller 20 may be a single chip microcomputer, and the electrical signal receiving terminals include, for example, an electrical signal receiving terminal P1 and an electrical signal receiving terminal P2.
In addition, the first circuit configuration 110 further comprises a second monitoring module 30. The second monitoring module 30 is disposed in the same manner as the first monitoring module 10, that is, the second monitoring module 30 is provided with a second monitoring electrode 13b disposed in the same manner as the first monitoring electrode 13 a.
Further, the second ground terminal 14 of the first monitoring module 10 is electrically connected to the second ground terminal 14 of the second monitoring module 30. For example, when the monitoring circuits of the two are in a conducting state, that is, for example, the second grounding terminals 14 of the two are electrically connected to the condensed water of the water receiving tray 210, so that the monitoring terminal 16 of the first monitoring module 10 and the monitoring terminal 16 of the second monitoring module 30 are in the same state, thereby avoiding interference to the electrical signals formed at the monitoring terminals 16 of the two due to the connection of the second grounding terminals 14 of the two to different ground references, causing the electrical signals at the monitoring terminals 16 of the two to be inconsistent, and reducing the monitoring accuracy.
Further, the controller 20 is further provided with a third ground terminal, and the third ground terminal is electrically connected to the second ground terminal.
Preferably, the sampling circuit further includes a capacitor CE1, for example.
Preferably, the controller 20 is further provided with an electrical signal output, and the first circuit structure 110 further comprises an alarm 50, wherein the alarm 50 is electrically connected to the electrical signal output. For example, the alarm 50 may be a buzzer or a flash, and when the controller 20 displays an abnormal signal on the display panel 40, a corresponding electrical signal is transmitted to the alarm 50, so that the alarm performs a response action, that is, the buzzer rings or the flash flashes.
In order to facilitate understanding of the embodiments of the present invention, the following detailed description will be given:
the voltage input end 11 to first monitoring module 10 and second monitoring module 30 inserts safe voltage Vcc, is equipped with between voltage input end 11 and sampling end 15 with electrical apparatus, the resistance value of electrical apparatus is R1, and the resistance value of divider resistance 18 is R2, and when the second earthing terminal 14 of first monitoring module 10 communicated the interior comdenstion water of water collector of air conditioner, monitoring circuit was in the on-state. In practical cases, the condensed water contains impurities to provide the condensed water with conductive characteristics, and since the condensed water has weak conductive characteristics, a circuit electrode C can be disposed at the bottom of the water receiving tray to improve the conductive characteristics, so that the condensed water can be regarded as a resistor and divided into R4 and R5 with the same resistance value. R4 is close to the second ground 14 in the first monitoring module 10; r5 is close to the second ground 14 in the second monitoring module 30.
When the first monitoring electrode 13a and the second monitoring electrode 13b are not conducted with the condensed water in the water pan, the monitoring circuits of the first monitoring electrode 13a and the second monitoring electrode 13b are in a disconnected state, at this time, the capacitor CE1 is in a charging state, the voltage value obtained by sampling at the sampling end 15 of the first monitoring module 10 is Vd, the voltage value obtained by sampling at the sampling end 15 of the second monitoring module 30 is Ve, the controller 20 receives an electric signal from the sampling end 15 of the first monitoring module 10 and inputs the electric signal to the electric signal receiving end P1, and receives an electric signal from the sampling end 15 of the second monitoring module 30 and inputs the electric signal to the electric signal receiving end P2. As can be seen from the circuit principle, Vd ═ Ve ═ Vcc, this time can be regarded as a normal state, and at this time, the controller 20 displays a normal signal, for example, code 1, on the display panel 40.
When the first monitoring electrode 13a or the second monitoring electrode 13b is electrically connected to the condensed water in the water pan 210, the corresponding monitoring circuit is in an on state, and at this time, the capacitor CE1 is in a discharging state, and according to the circuit principle, Vd ═ Vcc (R2+ R4)/(R1+ R2+ R4) or Ve ═ Vcc (R2+ R4)/(R1+ R2+ R4). Then, the controller 20 compares the voltage value Vd at the monitoring terminal 16 at this time with Vcc (R2+ R4)/(R1+ R2+ R4) and the voltage value Vd in the normal state with Vcc or Ve-Vcc (R2+ R4)/(R1+ R2+ R4) and Ve-Vcc, obviously, when Vd ≠ Vcc or Ve ≠ Vcc, it is regarded as in the early warning state, at this time, an early warning signal is generated in the controller 20, and the controller 20 sends the early warning signal from the control display terminal to the display panel 40, and the display panel 40 displays a first abnormal signal corresponding thereto, for example, code 2.
Because there is an installation error in the installation process of the internal unit of the air conditioner, that is, the horizontal plane of the condensed water in the water pan 210 cannot be electrically connected to the first monitoring electrode 13a and the second monitoring electrode 13b at the same time. Therefore, if the controller 20 receives the electrical signal at the electrical signal receiving end P1 first, and the voltage value at the monitoring end 16 is Vd ═ Vcc (R2+ R4)/(R1+ R2+ R4), the controller 20 controls the compressor of the air conditioner to continue the operation time T, where the time T is the set allowable installation levelness error, that is, the condensed water collected in the water receiving tray does not overflow during the time T when the compressor continues to operate.
Then, during the running time T of the compressor, if the controller 20 receives the electrical signal at the electrical signal receiving end P2 later, which can correspond to the voltage value Ve at the monitoring end 16 in the second monitoring module 30 being Vcc (R2+ R4)/(R1+ R2+ R4), the controller 20 controls the display panel 40 to display a first alarm signal, which indicates that the installation level is normal and the condensed water level is higher than the pre-warning water level, for example, code 3.
After the compressor continues to operate for time T, if the voltage value of the electric signal received by the controller 20 at the electric signal receiving end P2 corresponding to the monitoring end 16 in the second monitoring module 30 is Ve-Vcc, at this time, the controller 20 displays a second alarm signal on the display panel 40, where the second alarm signal indicates that the installation levelness is abnormal and the condensed water level is greater than the early warning water level, and the second alarm signal is, for example, code 4.
More specifically, the second alarm signal also indicates that the side of the water pan 210 close to the first monitoring electrode 13a is at a low position, and the opposite side of the water pan close to the second monitoring electrode 13b is at a high position, that is, a vertical inclination state is formed, and the controller 20 controls the compressor to stop, so that the alarm 50 performs a response action.
In contrast, when the voltage value corresponding to the electric signal received by the controller 20 at the electric signal receiving terminal P2 is Ve-Vcc (R2+ R4)/(R1+ R2+ R4), and the voltage value corresponding to the electric signal received by the electric signal receiving terminal P1 is Vd-Vcc, the second monitoring electrode 13b is at a low position and the first monitoring electrode 13a is at a high position. At this time, the controller 20 displays a third alarm signal, such as code number 5, on the display panel 40 and controls the compressor to be turned off so that the alarm 50 performs a response action.
Example two:
referring to fig. 3, a schematic diagram of a second circuit structure 120 of the water level monitoring device according to the second embodiment of the invention is shown. The difference between the first embodiment and the second embodiment is that the second circuit structure 120 in the present embodiment is electrically connected to the condensed water in the water tray 210 by using the Vref1 pin and the Vref2 pin in the triode, so as to form an electrical signal, which is transmitted to the electrical signal receiving end of the controller 20. That is, when the Vref1 pin is electrically connected to the condensed water, it can be regarded that the condensed water in the water tray 210 is at the early warning water level, otherwise, it can be regarded that the condensed water does not reach the early warning water level.
In one embodiment, the transistors include, for example, a first transistor 71 and a second transistor 72, wherein an output terminal of the first transistor 71 is electrically connected to an electrical signal receiving terminal P1 of the controller 20, and a Vref1 pin is provided for monitoring water level information in the water receiving tray, that is, similar to the monitoring function of the first monitoring electrode 13 a; the output end of the second triode 72 is electrically connected with an electrical signal receiving end P2 of the controller 20, and is provided with a Vref2 pin for monitoring water level information in the water pan, that is, similar to the monitoring function of the second monitoring electrode 13 b.
Of course, when the Vref1 pin and the Vref2 pin are electrically connected to the condensed water at the same time, the controller 20 displays the first alarm signal, i.e., code 3, on the display panel 40, and when neither the Vref1 pin nor the Vref2 pin is electrically connected to the condensed water, the controller 20 transmits a no-electric signal to two electric signal receiving terminals of the controller 20, and at this time, the controller 20 displays a normal signal, i.e., code 1, on the display panel 40.
In addition, when the Vref1 pin is electrically connected to the condensed water and the Vref2 pin is not electrically connected to the condensed water, at this time, the first triode 71 transmits the electrical signal to the electrical signal receiving terminal P1 electrically connected to the controller 20, and at this time, the controller 20 displays the code 4 on the display panel 40, that is, the side of the water receiving tray near the Vref1 pin is a low position, and the side of the water receiving tray near the Vref2 pin is a high position.
On the contrary, the controller 20 displays the code 5 on the display panel 40, that is, the side of the water pan near the pin Vref1 is high, and the side of the water pan near the pin Vref2 is low.
When the display panel 40 displays the code number 3 or 4 or 5, the controller 20 controls the compressor to shut down so that the alarm 50 performs a response action.
Example three:
an embodiment of the present invention provides an air conditioner, for example, including the water level monitoring apparatus as described in the first embodiment or the second embodiment, that is, including the first circuit structure 110 in the first embodiment or the second circuit structure 120 in the second embodiment.
Example four:
referring to fig. 4, a schematic flow chart of a water level monitoring method of an air conditioner according to a fourth embodiment of the present invention is shown. The water level monitoring method adopts the air conditioner described in the third embodiment, and the water level monitoring method includes:
step S10 is to obtain water level information in the water pan 210 of the air conditioner;
step S20 is to determine whether the water level information satisfies the pre-warning condition in the water pan 210;
step S30, when the early warning condition is judged to be satisfied, performing anti-overflow water control; the anti-flooding control includes: the controller 20 sends a signal to stop the compressor of the air conditioner.
The step S10 specifically includes: s11: turning on the air conditioner; s12, starting a refrigeration mode by the air conditioner; s13 normal operation of the compressor and the inner fan; the S14 water level monitoring electrode collects water level information within the drip tray 210.
The step S20 specifically includes: and judging whether the water level acquired by the first monitoring electrode 13a and/or the second monitoring electrode 13b is greater than or equal to the early warning water level, specifically, when the first monitoring electrode 13a and the second monitoring electrode 13b reach the early warning water level at the same time, judging that the installation levelness of the air conditioner indoor unit is normal at the moment, and otherwise, judging that the installation levelness is abnormal. When the warning condition of the step S20 is satisfied, the process goes to the step S30, and if the warning condition of the step S20 is not satisfied, the process goes to S13.
Wherein, the step S30 specifically includes: s31 the controller 20 controls the compressor to stop running; s32 displays the first alarm signal, the second alarm signal and the third alarm signal on the display panel 40 respectively, and controls the alarm 50 to perform a response action.
