Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid feeder having a fan driven by a drive motor, and an air conditioner, an air purifier, a dehumidifier, a humidifier, a heater and a ventilator provided with the fluid feeder. , A cooling device, and a heat exchange system.

[0002]

2. Description of the Related Art As an example of a conventional fluid feeder, a general air conditioner and its indoor unit will be described. FIG. 74 shows a cross section as viewed from the side of the indoor unit 1 of the conventional wall-mounted air conditioner. In the ventilation passage 4 limited by the fan casing 2 and the front panel 3, a suction grill 5 is provided.
The heat exchanger 6 is disposed so as to be opposed to. An air filter 7 is provided upstream of the heat exchanger 6, and a once-through fan 8 is provided downstream.

[0003] A drain pan 9 is provided below the heat exchanger 6. Horizontal louvers 11a and 11b and a vertical louver 12 are disposed at a main outlet 10 provided at a lower portion of the front panel 3.

[0004] During operation of the air conditioner 1, the flow-through fan 8 rotates, and a refrigerant from an outdoor unit (not shown) circulates in the heat exchanger 6. Thereby, when the room air is sucked into the ventilation passage 4 from the suction grill 5 and flows through the air filter 7, dust contained in the room air is removed by the air filter 7. The room air exchanges heat with the refrigerant in the process of flowing through the heat exchanger 6 to be cooled or heated, and is sucked and energized by the cross-flow fan 8, and then blown out by the vertical louvers 12 and the horizontal louvers 11a and 11b. And is blown into the room from the main outlet 10.

[0005]

In the above-mentioned conventional air conditioner indoor unit, minute dust in the room air that has passed through the air filter may adhere to and accumulate on the once-through fan 8. In this case, the rotational balance of the once-through fan 8 deteriorates, which causes noise. Further, there is a problem that the amount of air blown by the once-through fan 8 is reduced, the fan driving torque is increased by the weight of the dust accumulation, and the energy saving of the air conditioner is significantly impaired.

[0006] Further, there is a case where mold or the like is generated in the dust accumulated in the once-through fan 8, which is not only unsanitary but also has a problem that the human body may be adversely affected.

Therefore, in order to remove dust and prevent the generation of mold and the like, the fluid feeder may be disassembled and the once-through fan 8 may be periodically cleaned, but not only requires cleaning labor but also disassembly. At times, the rotational balance of the once-through fan 8 deteriorates,
The problem that noise rises remarkably arises.

In addition, a thermistor for sensing the temperature of the heat exchanger in the vicinity of the heat exchanger or in contact with the heat exchanger is generally installed in the indoor unit of the conventional air conditioner. When the controller detects an abnormal decrease or increase in the temperature of the heat exchanger, the discharge amount can be adjusted by, for example, decreasing the refrigerant discharge amount of the compressor.

When dust accumulates in the flow-through fan of the conventional air conditioner in which the thermistor is installed and the air volume is significantly reduced, the following problems occur during the cooling operation and the heating operation.

[0010] In the case of the cooling operation, since the air volume decreases, the heat exchange amount of the heat exchanger decreases, and the refrigerant cannot absorb sufficient heat, so that the temperature of the heat exchanger is lower than usual. The thermistor detects the temperature decrease of the heat exchanger and reduces the refrigerant discharge amount of the compressor, that is, the refrigeration capacity, thereby recovering the temperature decrease. In this case, there is a possibility that the time required to reach the set temperature becomes longer or the temperature cannot be reached, and there is a problem that the comfort of cooling is significantly impaired.

[0011] In the case of the heating operation, since the air flow decreases, the heat exchange amount of the heat exchanger decreases, and the refrigerant cannot release sufficient heat, so that the temperature of the heat exchanger rises compared to the normal case. The thermistor detects the temperature rise of the heat exchanger and recovers the above temperature rise by reducing the refrigerant discharge amount of the compressor, that is, reducing the heating capacity. In this case, there is a possibility that the time required to reach the set temperature becomes longer or the temperature cannot be reached, and there is a problem that heating comfort is significantly impaired.

Further, in the case of a conventional air conditioner, when the thermistor is damaged for some reason, or when dust accumulates in the flow-through fan of the conventional air conditioner that is not installed from the initial state, the air volume is significantly reduced. Causes the following problems during the heating operation and the cooling operation.

[0013] During the cooling operation, the air flow decreases, the heat exchange amount of the heat exchanger decreases, and the refrigerant cannot absorb sufficient heat, so that the temperature of the heat exchanger is lower than usual. When the operation is continued, dew condensation on the heat exchanger increases due to the above-mentioned temperature drop, and the pressure loss increases, so that the air volume further decreases. for that reason,
Further, the temperature of the heat exchanger is reduced, and the condensed water freezes, resulting in a further pressure loss and a reduction in air volume. When the operation is further continued, ice formed by freezing of dew condensation water grows. At this time, when a part of the ice that has protruded from the heat exchanger and has grown is melted, and water drops drop on the once-through fan, water is blown out from the main outlet. Further, when the ice formed by the freezing of the dew condensation water grows in the gap between the structures of the indoor unit, a phenomenon such as pushing up of the structure by the ice occurs, causing a problem in the structure or a problem in the structure. Cracks may occur. further,
If the temperature of the heat exchanger drops significantly, dew condensation also occurs on the main unit casing of the indoor unit of the air conditioner, and in this case, dew condensation water drops on the floor.

As described above, the property of the user may be damaged, such as spraying water on the user, flooding the user's room, or damaging the indoor unit of the air conditioner. It could be a big problem.

At the time of the heating operation, the air volume decreases, and the heat exchange amount of the heat exchanger decreases, and the refrigerant cannot release sufficient heat. If the operation continues, the compressor pressure will increase due to the increase in the refrigerant pressure, and the compressor temperature will increase, causing the compressor to burn or the refrigerant pressure to increase, so that the welded portion of the heat transfer tube, etc. There is a risk that the refrigerant may leak from a part where the pressure is partially weakened, or in the worst case, the problem may occur that the heat transfer tube ruptures.

Further, in the air purifier, when a large amount of dust accumulates in the fan and the air volume of the fan decreases, the air purifying ability is reduced, that is, smoke, dust, and dead mites of cigarettes. Since the ability to remove allergens such as pollen and pollen is reduced, not only the convenience of the user is greatly impaired, but also the human body may be adversely affected.

In the dehumidifier, when a large amount of dust accumulates in the fan and the air flow of the fan is significantly reduced, the dehumidifying capacity is reduced, and the convenience of the user is greatly impaired. A problem similar to the problem occurring in the indoor unit of the harmony device may occur.

Further, in the humidifier, when a large amount of dust accumulates in the fan and the air flow of the fan is significantly reduced, there is a problem that the humidifying ability is reduced and the convenience of the user is greatly impaired. . In addition, if the dust accumulated on the fan peels off for some reason and is transported to the heating plate or the vicinity of the heating element by the blower of the fan, the peeled dust may ignite. If it does not work properly, there is a risk that the humidifier body will ignite, and in the worst case, it will catch fire. In the case where the dust is largely peeled off for some reason, for example, a centrifugal force is applied to a place where the dust having a predetermined mass or more is accumulated, and the force due to the centrifugal force is larger than the force that the dust is attracted to the blower. It means that it comes off when it becomes.

In a fan heater as a heater, when dust accumulated in the fan is largely peeled off for any reason, the peeled dust is carried to the combustion chamber by the blower of the fan and burned in the combustion chamber. You. Thereafter, the dust is discharged as ash from the main outlet, and there is a problem that ash falls on the user or the room is stained with ash. Furthermore, if a large amount of dust accumulates in the fan and the airflow of the fan decreases by a large amount, the time to reach the comfortable temperature may be prolonged, or it may not be possible to reach the comfortable temperature.
There was a problem that the comfort of heating was significantly impaired.

Further, when a large amount of dust accumulates in the fan and the air flow of the fan is greatly reduced, the temperature of the combustion chamber may increase, and the safety device may not operate normally for some reason. In such a case, there is a risk that the main body of the fan heater is ignited, and in the worst case, a fire is caused.

In the underfloor ventilation fan as a ventilation device, when a large amount of dust accumulates in the fan and the airflow of the fan is significantly reduced, the ventilation capacity is reduced.
There is a problem in that the ability to discharge the moist air accumulated under the floor of the house to the outside is reduced, so that the house cannot be protected from damage by termites and mites.

In a CPU cooling device as a cooling device, when a large amount of dust accumulates in the fan and the airflow of the fan is significantly reduced, or when the dust accumulated in the fan is peeled off for some reason, the fan is largely separated. If the heat is carried to the heat sink by the air blow and the heat sink is clogged, the cooling capacity of the CPU decreases, and
There has been a problem that the humidity of the PU rises and the CPU cannot withstand the heat load, malfunctioning or being damaged. If the CPU temperature rises abnormally, this CP
Since the temperature of the inside of the device equipped with U and the temperature of the casing also increases, there is a danger that other components constituting the device may be damaged or a user may be burned.

In a radiator as a heat exchange system, when a large amount of dust accumulates in the fan and the air flow of the fan is significantly reduced, or when the dust accumulated in the fan is largely peeled off for some reason, the dust is removed from the fan. If the radiator is carried into the core by blowing air and clogged, there is a problem that the heat exchange capacity of the radiator is reduced, and the capacity of the entire system including the radiator is reduced.
