Detailed Description

So that the manner in which the above recited objects, features and advantages of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments.

Embodiment one:

referring to fig. 1, the present embodiment provides a float switch 1, the float switch 1 including: reed switch 50; the floater 40 is arranged outside the reed pipe 50 and sleeved on the reed pipe 50, and the floater 40 is used for moving relative to the reed pipe 50; the self-repairing device 60, the self-repairing device 60 is connected with the end part of the reed switch 50; wherein, when the float 40 cannot fall back by itself, the self-repairing device 60 attracts the float 40 to complete the fall back.

In this embodiment, the low water level is a normal water level, and the high water level is an abnormal water level. The reed switch 50 is internally provided with a magnetic reed switch, and the magnetic reed switch is normally closed, and is in a fitting state under the self elasticity under the action of the elasticity when the floater 40 is positioned at a low water level in general cases; when the water level in the air conditioner rises, the floater 40 moves relative to the reed pipe 50 under the action of the buoyancy, the floater 40 reaches a high water level position in the air conditioner, the magnetic reed switch is disconnected and attached under the action of the annular magnet in the floater 40, and the circuit is in a disconnected state. Wherein, the laminating of two reed switches can form complete return circuit, and after the reed switch disconnection, the circuit disconnection to the water pump of control air conditioner opens, begins the work of drawing the comdenstion water.

Wherein, the float 40 is made of a material with smaller density, which is convenient for the float to normally change along with the change of the water level under the combined action of buoyancy and self gravity, and accurately represents the water level. Meanwhile, the float switch 1 is mounted on the wire sleeve hose through the fixing nut 10, the sealing coil 20 prevents water from entering, and the wire locking buckle 30 further fixes the float switch 1.

Further, a self-repairing device 60 is fixedly connected to the end of the reed pipe 50, and when the float 40 cannot fall back due to the blockage of foreign matters, the self-repairing device 60 is started to attract the float 40 with abnormal water level to fall back to the normal water level, so that the air conditioner can work normally.

Embodiment two:

referring to fig. 1 to 2, in the present embodiment, the self-repairing apparatus 60 includes: a stopper 601, the stopper 601 being connected to an end of the reed switch 50; an electromagnet 602, the electromagnet 602 being disposed within the stop 601; the float 40 includes: a first magnet 401, the first magnet 401 being disposed within the float 40; wherein the electromagnet 602 is used to attract the first magnet 401 such that the float 40 falls back.

In this embodiment, the stop member 601 is a main body portion of the self-repairing device 60, the stop member 601 is specifically a U-shaped retainer ring, and similarly, the U-shaped retainer ring is sleeved at an end portion of the reed pipe 50 and is used for stopping the float 40 from falling out of the reed pipe 50, meanwhile, an electromagnet 602 is disposed in the stop member 601, a first magnet 401 is disposed in the float 40, the first magnet 401 is specifically a ring-shaped magnetic ring structure, when the self-repairing device 60 is started, the electromagnet 602 is electrified, and at this time, the electromagnet 602 has a strong attractive force on the first magnet 401 in the float 40 to suck the float 40 back against the stop member 601.

It should be noted that, the first magnet 401 is an external excitation input that affects the start and stop of the reed switch inside the reed switch 50. Likewise, when the electromagnet 602 is not energized, the electromagnet 602 is not magnetic, and when the electromagnet 602 is not energized, the influence of the electromagnet 602 on the first magnet 401 in the float 40 is negligible. In the energized state, the electromagnet 602 has a strong magnetic force, and can generate a magnetic attraction force on the first magnet 401 in the float 40, so that the float 40 falls back from the abnormal water level to the normal water level. The electromagnet 602 circuit and the float switch 1 circuit are two complete circuits, and have no synchronism with each other.

The abnormal water level is the high water level in the air conditioner, and the normal water level is the low water level in the air conditioner.

Further, the electromagnet 602 is a device that generates electromagnetic electricity by being energized, and a wire matched with the power of the electromagnet is wound on the outside of the iron core, so that the coil has magnetic force like a magnet. According to an empirical formula, the magnitude of the magnetic force is in direct proportion to the square of the electrified current.

Embodiment III:

the present embodiment provides a control method of a float switch, the control method being used for controlling the float switch according to any one of the above embodiments, the control method including:

detecting the water level of the floater;

judging whether the floater is positioned at an abnormal water level;

if the floater is positioned at the abnormal water level, the self-repairing device in the floater switch is controlled to be electrified so that the floater falls back to the normal water level.

When the floater is detected to be at the high water level, the floater is at the abnormal water level, and the floater is at the abnormal water level, which possibly cannot fall back due to blockage of foreign matters, or the water level in the air conditioner is actually at the high water level, the embodiment only analyzes the condition that the floater is at the high water level due to the foreign matters, and the controller controls the electromagnet of the self-repairing device to be electrified, so that the floater is pulled back to the normal water level from the abnormal water level, and the operation such as normal operation is convenient for starting of the subsequent air conditioner.

Embodiment four:

in this embodiment, before detecting the float water level, the method further includes:

detecting the original water level of the floater;

judging the water level of the floater, and controlling the water pump;

if the floater is positioned at the abnormal water level, controlling the water pump to be started so as to perform drainage action;

and if the floater is positioned at the normal water level, controlling the water pump to be closed.

In this embodiment, it is specifically described that the three embodiments require the water pump draining operation before detecting the float water level, so as to eliminate the situation that the actual water level is at the high water level, and thus the float is at the abnormal water level.

Specifically, it is necessary to detect and determine what kind of water level the original position of the float is located, if the float is located at the abnormal water level at the original position, then the float is located at the high water level, and it is necessary to control the water pump to perform the water draining operation first, and then detect whether the position of the float is still at the abnormal water level once after the water draining operation, and execute the control method of the third embodiment.

If the floater is positioned at the normal water level at the moment, the floater is positioned at the low water level at the moment, and the air conditioner can be started up normally to work.

Fifth embodiment:

in this embodiment, if the float is located at an abnormal water level, the water pump is controlled to be turned on to perform a water draining operation, and the method further includes:

judging the drainage time of the water pump;

if the water draining time of the water pump is longer than the first set time, controlling the electromagnet of the self-repairing device to be electrified;

and if the water draining time of the water pump is less than or equal to the first set time, controlling the water pump to be kept on so as to continuously perform the water draining operation.

In this embodiment, the water pump is controlled to be started for draining based on the four controllers of the embodiment, specifically, in the process of pumping and draining of the water pump, the draining time of the water pump is judged, the first set time is the default setting time of the air conditioner when leaving the factory, and the setting adjustment can be performed according to different working conditions, and in this embodiment, the first set time is 3 minutes.

Specifically, when the water pump drainage operation is executed, firstly, the electronic expansion valve in the air conditioner is delayed to be opened for 1 minute, meanwhile, the fan in the air conditioner is operated for 1 minute at a low speed, then the windshield is rotated and set to prevent the air conditioner from blowing water, then the water pump is opened, condensate water drainage action is performed, at the moment, timing is started, when the water pump opening time reaches 3 minutes, namely, the water pump opening time is more than 3 minutes, the position of the floater at the moment is judged, and if the floater is positioned at a high water level, namely, the floater is positioned at an abnormal water level, the electromagnet is controlled to be electrified to attract the floater to fall back, so that the problem that foreign matters are blocked to fall back is solved.

When the water pump is started for 3 minutes or less, when attention is needed at this time, judging what water level the floater is at, and if the floater is still at a high water level at this time, namely when the floater is at an abnormal water level, controlling the water pump to continuously drain by the controller at this time.

Further, under the general conditions, the condensed water in the water receiving tray can be discharged by the water pump drainage for 3 minutes through a large number of experimental tests.

Example six:

in this embodiment, controlling the water pump to be turned on to perform the water draining operation further includes:

judging the position of the floater once every time the second set time passes in the drainage process;

if the position of the floater is located at the abnormal water level, controlling the water pump to work normally;

and if the position of the floater is at the normal water level, controlling the water pump to stop working.

In this embodiment, during the process of controlling the water pump to drain by the controller, the position of the floater is detected once every time the second set time passes, and the second set time is factory default set time of the air conditioner, so that manual adjustment setting can be performed according to actual working conditions and needs. In this embodiment, the second set time is specifically 10 seconds, that is, the position of the float is detected once every 10 seconds, and when the float is detected to fall back to the normal water level in the draining process, the draining operation of the water pump is stopped, so that the air conditioner is started normally.

Embodiment seven:

in this embodiment, the electromagnet has an operating current, and the operating current includes: a lower limit value determined by the weight of the float; the upper limit value is determined by the combined action of the gravity of the floater and the buoyancy of the floater; wherein, the working current of the electromagnet in operation is between the upper limit value and the lower limit value.

The lower limit value is the minimum working current, and the upper limit value is the maximum working current.

In this embodiment, in order to ensure that the electromagnet can normally operate and ensure operation reliability, the magnitude of the energizing current is controlled as follows:

the minimum value of the current, i.e. the minimum operating current, is determined by the weight of the float, i.e. f=mg (float), by calculation in the early field, the current Imin (minimum operating current); in order to ensure the reliability of the air conditioner, the maximum working current is limited, so that the float is prevented from being forcibly pulled to a low water level under the condition of an actual high water level, and misjudgment is formed, namely F=mg (float) +F (float buoyancy), so that Imax (maximum working current) is determined.

The working current in the actual running process of the electromagnet is adjusted and set between the minimum working current and the maximum working current according to different using working conditions.

The larger current can generate larger electromagnetic force, and a large number of sheet metal parts are stored in the air conditioner, and the longer-term larger magnetic force can lead to deformation of the structure of the float switch, so that the reliability of the air conditioner is affected. The electrified time interval of the electromagnet is 12 seconds, and the float position detection time is 10 seconds, so that the float can be guaranteed to fall back under the condition of smaller current.

Example eight:

in this embodiment, after the self-repairing device in the float switch is controlled to attract the magnet in the float, the control method further includes:

judging the position of the floater;

if the floater is positioned at the abnormal water level, prompting the water pump to be out of order;

and if the floater is positioned at the normal water level, controlling the air conditioner to normally operate.

In the embodiment, the self-repairing device comprises a stop piece and an electromagnet, wherein the electromagnet is arranged in the stop piece, and the processing method that the electromagnet is electrified and still fails to pull the floater from the abnormal water level to the normal water level is specifically described. When the electromagnet in the stop piece is electrified, the floater is still located at an abnormal water level, namely, the floater cannot fall back to a normal water level from the abnormal water level, the air conditioner prompts an operator that the water pump fails, specifically, the water pump of the indoor unit fails, and at the moment, the electromagnet is powered off to wait for maintenance of the operator.

If the electromagnet is electrified and the floater falls back to the normal water level, the electromagnet is powered off, and the air conditioner works normally.

Example nine:

referring to fig. 3, the control method of the float switch is fully described in this embodiment.

The method starts in step S10, and the control method in this embodiment is applicable to the start-up of an air conditioner or an air conditioner in operation. Step S20 detects whether the position of the floater is at a low water level, if the position of the floater is at the low water level, namely, a normal water level, the air conditioner continues to normally operate in step S80, the U-shaped electromagnet, namely, the electromagnet arranged in the stop piece is powered off, or the U-shaped electromagnet is not powered on, and then the step S90 is ended.

If the float is at the high water level, that is, if the float is at the abnormal water level, the step S30 is entered, the water pump is started to remove water, then the step S40 is entered to judge whether the water pump is started for more than 3 minutes, if yes, the step S50 is entered, the U-shaped electromagnet is electrified to pull the float from the high water level to the low water level, thereby eliminating the phenomenon that the float is blocked by foreign matters from falling back, the step S60 is entered, whether the position of the float is at the low water level is further detected, if yes, the step S80 is entered, the air conditioner continues to operate, if no, the fact that the float is not pulled back to the low water level by the electromagnet is indicated, the water pump failure is indicated, and at the moment, the step S70 is entered, the indoor unit lifts the water pump to fail, and then the step S90 is entered to end.

Similarly, if the water pump on time in step S40 is 3 minutes or less, the process returns to step S30 to continue to start the water pump for water removal.
