In the related art, a drain structure is improved by adding a drain port in an air conditioner, but such a measure cannot prevent an accident from occurring.
According to an embodiment of the first aspect of the invention, the motor home air conditioner comprises an air conditioner body, a double-position liquid level sensor and a flow rate sensor.
The air conditioner body is an indoor unit part of a motor home air conditioner and is arranged on the inner wall of the motor home. The air conditioner body is communicated with the outdoor unit through a pipeline to transfer refrigerant and heat. The lateral part of the air conditioner body is provided with an air outlet which is arranged in the vehicle body along the horizontal direction. The outdoor unit of the motor home air conditioner is arranged outside the motor home, and rainfall easily enters the air conditioner body along the edge of the pipeline.
The plurality of double-position liquid level sensors are arranged in the air conditioner body and are connected to a chassis or a side wall in the air conditioner body. The plurality of dual-position liquid level sensors are uniform in height, and a space is reserved between two adjacent dual-position liquid level sensors. Taking two as an example, two double-position liquid level sensors are respectively arranged at two ends in the air conditioner body or are positioned at other proper positions in the air conditioner body. Each double-position liquid level sensor comprises a low-position detection end and a high-position detection end, wherein the heights of the plurality of low-position detection ends are consistent, and the heights of the plurality of high-position detection ends are consistent. Wherein, low level detection end, high level detection end and air outlet's elevation increase in proper order.
For convenience of description, the number of dual-position liquid level sensors and the number of flow rate sensors are taken as two examples, and the two dual-position liquid level sensors are respectively marked as a first dual-position liquid level sensor and a second dual-position liquid level sensor, and the two flow rate sensors are marked as a first flow rate sensor and a second flow rate sensor.
The two flow velocity sensors are arranged in the air conditioner body, and the two flow velocity sensors are arranged between the low-level detection end and the high-level detection end of the two double-position liquid level sensors in a one-to-one correspondence mode. That is, the first flow sensor is located between the low level detection end and the high level detection end of the first dual level sensor, and the second flow sensor is located between the low level detection end and the high level detection end of the second dual level sensor.
In some embodiments, the two-position liquid level sensor comprises a two-position hall liquid level sensor.
According to the caravan air conditioner provided by the embodiment of the invention, water level information and flow rate information in an air conditioner body are obtained through a plurality of double-position liquid level sensors and a plurality of flow rate sensors; and determining a drainage risk state according to the water level information and the flow rate information, and sending early warning information according to the drainage risk state. The structure of the motor home air conditioner can prevent accidents in advance without making great improvement.
In some embodiments, a first safety height is provided between the high-level detection end and the air outlet.
It can be understood that when the motor home is running, the bottom in the air conditioner body gradually gathers the comdenstion water from the evaporimeter and the outside rainwater etc. of motor home, if the outlet appears blockking up, the water level rises gradually, and rivers are possible to flow along the air outlet of air conditioner body. The high-level detection end and the air outlet are provided with a first safety height, when the water level rises to the high-level detection end, the drainage risk state is timely determined, and before water flows overflow the air outlet of the air conditioner body, early warning information is formed in advance and/or the air conditioner is controlled to stop running, so that the safety of the air conditioner of the motor home is improved. In some embodiments, the first safety height is at least 1cm.
Meanwhile, a second safety height is arranged between the low-level detection end and the lowest position in the air conditioner body. And when the condensed water is normally formed in the air conditioner body and the water level of the condensed water does not exceed the second safety height, drainage early warning measures do not need to be started. In some embodiments, the second safety height is at least 1cm.
It should be noted that, the car as a house air conditioner still includes control unit and suggestion subassembly etc., and suggestion subassembly, two dibit level sensor and two flow velocity sensor all signal connection in control unit. The control unit receives water level information from the double-position liquid level sensor, receives flow rate information from the flow rate sensor, determines a drainage risk state according to the water level information and the flow rate information, and then sends early warning information according to the drainage risk state.
Referring to fig. 1, the drainage early warning method of a motor home air conditioner provided according to the embodiment of the second aspect of the present invention includes the following steps:
s100, acquiring water level information and flow rate information in the air conditioner body.
S110, determining a drainage risk state according to the water level information and the flow rate information, and sending early warning information according to the drainage risk state.
It is understood that the first flow sensor is located between the low and high detection ends of the first dual level sensor and the second flow sensor is located between the low and high detection ends of the second dual level sensor. The water level in the air conditioner body can be obtained through the double-position liquid level sensor, and when the water level rises to the low-position detection end or the high-position detection end, the double-position liquid level sensor generates an induction signal which can be used as a signal for reaching the water level. For convenience of description, the number of the double-position liquid level sensors and the number of the flow rate sensors are taken as two as examples, and the steps of the drainage early warning method of the motor home air conditioner are described in detail:
the water level is detected at the two low-level detection ends at the same time, the flow velocity is not detected by the flow velocity sensor, and when the water level is not detected by the two high-level detection ends, the water drainage is stable, the water outlet is not blocked, and the drainage risk state is the normal drainage state.
The water level is detected at the two low-level detection ends at the same time, the same flow rate is detected by the two flow rate sensors, and when the water level is not detected by the two high-level detection ends, the water drainage flow is large, but the water drainage is still in a stable water drainage state, and the water drainage risk state is a normal water drainage state.
The water level is detected at the two low-level detection ends simultaneously, the same flow rate is detected by the two flow rate sensors, and when the water level is detected at the two high-level detection ends simultaneously, the drain pipe is blocked, and the drainage risk state is a drainage dangerous state.
The drainage risk state includes at least a normal drainage state, an abnormal drainage state, a dangerous drainage state, and the like. The air conditioner sends out early warning information to the user according to the drainage risk state, and reminds the user to close the air conditioner in time or clean the drainage pipe in time.
When the number of the double-position liquid level sensors and the number of the flow rate sensors are three or more, the monitoring of the water level and the flow rate is more accurate based on the same principle, and the drainage early warning of the motor home air conditioner is more accurate and effective.
The prompting component of the car as a house air conditioner comprises at least one of a display screen component, a loudspeaker component or a light component, and can remind a user of paying attention to the drainage risk state.
According to one embodiment of the present invention, the step of acquiring water level information and flow rate information in the air conditioner body specifically includes:
s101, determining that the water level reaches a first low-level detection end, and starting timing at a first time length;
s102, determining that the water level reaches a second low-level detection end, and starting timing for a second duration;
s103, determining that the water level reaches the first high-level detection end, and starting timing the third time length;
s104, determining that the water level reaches the second high-level detection end, and starting timing at the fourth time;
s105, acquiring a first flow rate through a first flow rate sensor, and acquiring a second flow rate through a second flow rate sensor;
s106, determining water level information in the air conditioner body according to the first time length, the second time length, the third time length and the fourth time length, and determining flow rate information at different positions in the air conditioner body according to the first flow rate and the second flow rate.
When the water level reaches the first low-level detection end, the controller starts timing from 0, and the first time length after the water level reaches the first low-level detection end is calculated. When the first duration is 0, the drainage speed is higher, and the drain pipe is not blocked.
When the water level reaches the second low-level detection end, the controller starts timing from 0, and calculates a second duration after the water level reaches the second low-level detection end.
When the water level reaches the first high-level detection end, the controller starts timing from 0, and calculates a third time length after the water level reaches the first high-level detection end. And when the third time length is 0, the drain pipe is free from blockage, and normal drainage can be realized.
When the water level reaches the second high-level detection end, the controller starts timing from 0, and the fourth time length after the water level reaches the second high-level detection end is calculated. And when the fourth time length is 0, the drain pipe is free from blockage, and normal drainage can be realized.
It will be appreciated that the water level information in the air conditioner body may be determined based on the first time period, the second time period, the third time period, and the fourth time period, and the flow rate information in the air conditioner body may be determined based on the first flow rate and the second flow rate.
The flow rate information reflects the rate at which the water level rises in the air conditioner body.
According to one embodiment of the present invention, the step of determining a drainage risk state according to water level information and flow rate information and transmitting early warning information according to the drainage risk state specifically includes:
s111, when the first time length is equal to the second time length, the first flow rate is equal to the second flow rate, and the third time length is equal to the fourth time length, determining that the drainage risk state is a drainage risk state, and sending out a first prompt instruction.
It can be understood that when the first time length is equal to the second time length, the first flow rate is equal to the second flow rate, and the third time length is equal to the fourth time length, the drain pipe at the chassis of the air conditioner body is indicated to be blocked, the water level synchronously rises to the two low-level detection ends and the two high-level detection ends, and the rising speed of the water level is the same. Under such circumstances, the water level may continue to rise to the air outlet, and then be poured into the caravan along the air outlet, resulting in damage to the electronic devices and living goods in the caravan. Therefore, the drainage risk state is the drainage risk state, and the controller sends out a first prompt instruction to remind a user that the water flow in the caravan is at risk of backflow.
According to one embodiment of the present invention, the step of determining a drainage risk state according to water level information and flow rate information and transmitting early warning information according to the drainage risk state specifically includes:
s112, when the first duration is not equal to the second duration, the first flow rate is equal to the second flow rate, and the third duration is not equal to the fourth duration, determining that the drainage risk state is a drainage risk state, and sending out a first prompt instruction.
It can be understood that when the first time length is not equal to the second time length, the first flow rate is equal to the second flow rate, and the third time length is not equal to the fourth time length, the water level rises quickly due to rainfall, but the water level is higher than the chassis, the drainage risk state is judged to be the drainage risk state, the controller sends out a first prompt instruction, and the user is reminded of the risk of backward flow of water in the caravan.
According to one embodiment of the present invention, the step of determining a drainage risk state according to water level information and flow rate information and transmitting early warning information according to the drainage risk state specifically includes:
s113, when the first duration is not equal to the second duration, the first flow rate is not equal to the second flow rate, and the third duration is not equal to the fourth duration, determining that the drainage risk state is an abnormal drainage state, and sending out a second prompt instruction.
It can be understood that when the first time length is not equal to the second time length, the first flow rate is not equal to the second flow rate, and the third time length is not equal to the fourth time length, the water level rises due to condensed water or rainfall, but due to drainage obstruction, the drainage risk state is judged to be a drainage abnormal state, and the controller sends a second prompt instruction to remind a user that the drainage abnormality exists in the motor home air conditioner. At this time, although there is no risk of water flowing backward in the car, further deterioration is not excluded, and thus further attention is also required.
According to one embodiment of the present invention, the step of determining a drainage risk state according to water level information and flow rate information and transmitting early warning information according to the drainage risk state specifically includes:
s114, when the first duration is not equal to the second duration, the first flow rate is not equal to the second flow rate, and the third duration is equal to the fourth duration, determining that the drainage risk state is an abnormal drainage state, and sending out a second prompt instruction.
It can be understood that when the first time length is not equal to the second time length, the first flow rate is not equal to the second flow rate, and the third time length is equal to the fourth time length, the water level rises quickly due to rainfall, the drainage risk state is judged to be the drainage abnormal state, and the controller sends a second prompt instruction to remind a user that the drainage abnormality exists in the motor home air conditioner. At this time, although there is no risk of water flowing backward in the car, further deterioration is not excluded, and thus further attention is also required.
According to one embodiment of the present invention, the step of determining a drainage risk state according to the water level information and the flow rate information and transmitting the pre-warning information according to the drainage risk state further includes:
