Description

Technical Field

[0001] The invention relates to the technical field of air conditioning equipment, and in particular to a mobile air conditioning water pumping motor. Background Art

[0002] A mobile air conditioner is a portable air conditioning device. Unlike traditional fixed air conditioning systems, a mobile air conditioner can be easily moved to a location that requires cooling without the need for a complicated installation process. A mobile air conditioner usually includes an indoor unit and an outdoor exhaust pipe, through which hot air is discharged to the outdoors, thereby achieving a cooling effect. However, the structure of a mobile air conditioner is basically similar to that of a fixed air conditioner, with a condenser, evaporator, etc. in its composition. The difference is that a fixed air conditioner collects the condensed water on the evaporator and then discharges it to the outdoors through a pipe, while a mobile air conditioner collects the condensed water on the evaporator and sprays the condensed water onto the condenser through a water-pumping motor (that is, a motor device that can spray and lift water in a water tank through devices such as impellers) to accelerate heat exchange, thereby improving energy efficiency and avoiding shutdowns caused by rapid accumulation of condensed water.

[0003] However, the water pumping motors in current mobile air conditioners are all started when the mobile air conditioner is started, and the operating power is uncontrollable and cannot be adjusted according to the actual situation, resulting in energy waste. In particular, when there is only a small amount of condensed water in the water tank for collecting condensed water and it is not enough for extraction, the water pumping motor is idling, which consumes energy and greatly reduces the life of the water pumping motor.

[0031] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-5As shown, a mobile air-conditioning water pumping motor comprises an upper end cover 2 and a lower end cover 3 arranged at the lower part of the upper end cover 2, a fixing pile 11 is arranged in the middle of the upper end cover 2, a through hole 10 penetrating the upper and lower surfaces thereof is arranged in the fixing pile 11, a circuit board 9 is fixedly arranged near the top in the upper end cover 2, the circuit board is electrically connected to a wiring harness 13 arranged outside the upper end cover, a stator 8 is arranged at the lower end of the circuit board 9, and the stator 8 is fixedly arranged on the outer surface of the fixing pile 11, and the circuit board 9 is electrically connected to the stator 8; equidistantly arranged reinforcing ribs 5 are arranged on the inner wall of the hollow interior of the lower end cover 3, a connecting reinforcing portion 12 is arranged at the inner bottom of the lower end cover 3, the connecting reinforcing portion 12 is rotatably connected to the rotating shaft 1, the rotating shaft 1 is upwardly penetrated into the through hole 10 of the fixing pile of the upper end cover 2, and passes out through the through hole 10, an impeller 4 is fixedly installed on the top of the rotating shaft 1, and a A shielding plate 7, a rotor 6 is fixedly provided on the outer side of the upper surface of the shielding plate 7, and the rotor 6 is sleeved on the outer side of the stator 8; the impeller 4 is arranged in the water tank, and a pressure sensor is arranged at the bottom of the water tank; it also includes a water pumping motor control system, and the water pumping motor control system includes a water pressure data collection unit, a water depth judgment unit, a planned data calculation module, an actual data calculation module, a planned and actual data difference calculation unit and a water pumping motor working state control unit; firstly, the circuit board 9 is energized through the wiring harness 13, so that the stator 8 generates a magnetic field, and the rotor 6 rotates under the action of the magnetic field, and the rotor transmits the rotating shaft 1 through the shielding plate 7, and the rotating shaft 1 drives the impeller 4 to rotate, and this rotation produces an effect similar to centrifugal force, that is, a low-pressure area is generated around the impeller 4, and condensed water tends to fill this low-pressure area, so the water is sucked in and sprayed onto the condenser.

[0033] The output end of the water pressure data collection unit is unidirectionally connected to the input end of the water depth judgment unit and the water pumping motor working state control unit, the negative output end of the water depth judgment unit is unidirectionally connected to the input end of the water pressure data collection unit, the positive output end of the water depth judgment unit is unidirectionally connected to the input end of the planned data calculation module and the actual data calculation module, the output end of the planned data calculation module and the actual data calculation module is unidirectionally connected to the input end of the calculation and actual data difference calculation unit, and the output end of the actual data difference calculation unit is unidirectionally connected to the input end of the water pumping motor working state control unit;

[0034] The water pressure data receiving unit is used to collect data on the water pressure in the water tank through the pressure sensor disposed at the bottom of the water tank; because the water pressure is greater than the atmospheric pressure, when there is condensed water in the water tank, the pressure sensor will detect the pressure value;

[0035] The water depth judgment unit is used to calculate the water depth of the condensed water in the water tank according to the liquid pressure formula: P = ρgh, and judge whether the water depth meets the normal operation requirements of the water pumping motor; the water tank is a geometric straight cylinder with uniform density, and its upper and lower bottom areas are equal, so the depth of the condensed water in the water tank can be calculated by the formula;

[0036] The planned data calculation module is used to calculate the planned spraying rate required to keep the condenser temperature at the optimal working temperature by continuously receiving current data from the temperature sensor used to detect the condenser temperature;

[0037] The actual data calculation module is used to calculate and verify the actual spraying rate of condensed water generated on the evaporator and available for spraying;

[0038] The planned and actual data difference calculation unit is used to calculate the difference between the planned spraying data and the actual spraying data, so as to facilitate the subsequent adjustment of the working state of the water pumping motor; by calculating the difference, it can be known whether the current condensed water output satisfies the spraying of the condenser, so as to keep the condenser always within the optimal working temperature range;

[0039] The water pumping motor working state control unit is used to adjust the working state of the water pumping motor according to the difference between the planned spraying data and the actual spraying data and the amount of condensed water in the current water tank; when the planned spraying amount is less than the actual spraying amount, the planned spraying amount can be equal to the actual spraying amount by reducing the water pumping motor power, thereby ensuring that the condenser is always within the optimal operating temperature range and reducing the energy consumption of the water pumping motor. The amount of condensed water in the water tank is when the water tank is about to be fully loaded, and the water pumping motor power is timely increased to increase the consumption of condensed water; when the planned spraying amount is greater than the actual spraying amount, the water pumping motor power is adjusted to the maximum to speed up the heat exchange of the condenser, and the amount of condensed water in the water tank is when the water tank is about to reach the minimum water volume, and the water pumping motor power is timely adjusted to keep the consumption of condensed water equal to the output.

[0040] The planned data calculation module includes a temperature data collection unit, a temperature step matching unit, a temperature change rate calculation unit and a planned spray rate calculation unit;

[0041] The input end of the temperature data collection unit is unidirectionally connected to the output end of the temperature sensor for detecting the temperature of the condenser, the output end of the temperature data collection unit is unidirectionally connected to the input end of the temperature step matching unit and the temperature change rate calculation unit, and the output end of the temperature step matching unit and the temperature change rate calculation unit is unidirectionally connected to the input end of the planned spray rate calculation unit;

[0042] The temperature data collection unit is used to collect the condenser temperature data detected by the temperature sensor in real time;

[0043] The temperature step matching unit is used to grade the temperature collected on the condenser into steps, and each step corresponds to a different planned spray rate;

[0044] The temperature change rate calculation unit is used to calculate the condenser temperature data collected in real time to obtain a specific value of the condenser temperature change rate per unit time;

[0045] The planned spray rate calculation unit is used to combine the data of the temperature step matching unit and the temperature change rate calculation unit to perform calculations, so as to obtain the current and future planned spray rates; the currently output planned spray rate is the planned spray rate corresponding to the current temperature level; the future spray rate after a specific time is the planned spray rate corresponding to the current temperature level ± the required spray rate corresponding to the current temperature change rate.

[0046] The actual data calculation module includes an air volume data collection unit, an indoor data collection unit, a condensed water output rate calculation unit, an output rate verification unit and an actual spray rate calculation unit; the input ends of the air volume data collection unit and the indoor data collection unit are unidirectionally connected to the output end of the control system of the mobile air conditioner, the output ends of the air volume data collection unit and the indoor data collection unit are unidirectionally connected to the input end of the condensed water output rate calculation unit, the output end of the condensed water output rate calculation unit is unidirectionally connected to the input end of the output rate verification unit, the input end of the output rate verification unit is unidirectionally connected to the output end of the water pressure data collection unit, and the output end of the output rate verification unit is unidirectionally connected to the input end of the actual spray rate calculation unit;

[0047] The air volume data collection unit obtains data on the current air volume of the air conditioner by connecting to the mobile air conditioner control system;

[0048] The indoor data collection unit obtains the current indoor air temperature and humidity by connecting to the mobile air conditioning control system; the condensation water output rate calculation unit is used to calculate the condensation water output rate according to the current air volume, the current indoor air temperature and humidity;

[0049] The output rate verification unit is used to verify the output rate calculated based on the water pressure change rate in the water tank to ensure that the calculated value is within the allowable error range; because the actual condensed water does not fall all and timely and be collected in the water tank during condensation, the output rate verification unit is used to ensure that the actual spray rate is within the error range for output;

[0050] The actual spray rate calculation unit is used to calculate according to the current water depth in the water tank and the calculated output rate value, and obtain the actual spray rate that the water pumping motor can achieve per unit time.

[0051] The specific implementation is as follows:

[0052] When the water depth in the water tank in the mobile air conditioner cannot support the normal operation of the water pumping motor, the water depth judgment unit continuously judges the data obtained by the water pressure data collection unit at specific intervals until the water depth in the water tank meets the minimum water volume for the normal operation of the water pumping motor. The current spray rate and the future spray rate after a specific time in the future are collected and calculated through the temperature data collection unit, the temperature step matching unit, the temperature change rate calculation unit and the planned spray rate calculation unit in the planned data calculation module; the actual spray rate that can be achieved by the current water pumping motor is obtained through the air volume data collection unit, the indoor data collection unit, the condensed water output rate calculation unit, the output rate verification unit and the actual spray rate calculation unit in the actual data calculation module. The planned and actual data difference calculation unit performs difference calculation to facilitate subsequent adjustment of the working state of the water pumping motor, and the working state of the water pumping motor is adjusted through the water pumping motor working state control unit. When the planned spraying amount is less than the actual spraying amount, the planned spraying amount can be equal to the actual spraying amount by reducing the water pumping motor power, thereby ensuring that the condenser is always within the optimal working temperature range and reducing the energy consumption of the water pumping motor. The amount of condensed water in the water tank is when the water tank is about to be fully loaded, and the water pumping motor power is timely increased to increase the consumption of condensed water; when the planned spraying amount is greater than the actual spraying amount, the water pumping motor power is adjusted to the maximum to accelerate the heat exchange of the condenser, and the amount of condensed water in the water tank is when the water tank is about to reach the minimum water volume, and the water pumping motor power is timely adjusted to keep the consumption of condensed water equal to the output. By setting the pressure sensor in the water tank to collect water pressure data, the depth of condensed water in the water tank can be obtained. By ensuring that there is a minimum amount of water in the water tank before starting the water pumping motor, and using the data obtained by the planned data calculation module and the actual data calculation module to perform difference calculation, not only can the water pumping motor be regulated to the optimal power when the planned value is less than the actual value, but also when the planned value is greater than the actual value, the water depth in the water tank can be detected to control the working state of the water pumping motor according to actual conditions. This solves the problem mentioned in the background technology that "the water pumping motors in current mobile air conditioners are all started when the mobile air conditioner is started, and the operating power is uncontrollable, and the power cannot be adjusted according to actual conditions, resulting in a waste of energy. In particular, when there is only a small amount of condensed water in the water tank for collecting condensed water, which is insufficient for extraction, the water pumping motor is idling, which consumes energy and greatly reduces the life of the water pumping motor."

[0053] The present invention and its embodiments are described above, which is not restrictive. What is shown in the accompanying drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and do not deviate from the purpose of the invention, they can creatively design structural methods and embodiments similar to the technical scheme, which should all fall within the scope of protection of the present invention.
