JPH06129656A - Air conditioning device with fungs prevention function - Google Patents

Abstract

PURPOSE:To make it possible to exert its functions which prevent the generation of-fungi and bacterium effectively by operating heat supply equipment or an electric heater with a fan halted. CONSTITUTION:When carrying out fungus removal operation, a cooling/heating changeover knob is set to 'fungus removal' and an operation/stop pushbutton switch is depressed. Then, after a flap closed state and a fan stop state (steps a and b), heat supply equipment is started (step c). Then, it is determined whether or not equipment temperature exceeds a setting value (step d). If the equipment temperature is less than the setting value, the operation of the equipment is continued in the loop of d-c-d. When the equipment temperature exceeds, the setting temperature, the heat supply equipment comes to a halt (step e). In this manner, the equipment temperature is controlled so as to keep a definite temperature (such as 60 deg.C). If a definite time (such as one hour) has elapsed, fungus removal operation will come to an end step f).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having a function of preventing the generation of mold and bacteria.

[0002]

2. Description of the Related Art In recent years, one of the causes of allergic diseases has been the occurrence of mold in the air-conditioning system. As a countermeasure against this, the air intake filters and internal parts of indoor units have contained fungicides and antibacterial agents. Air-conditioning systems have been developed that prevent the generation of mold and bacteria by applying paint.

[0003]

However, it is said that the antifungal and antibacterial agents of this type generally lose their effectiveness after about one year has passed, and in the above-mentioned conventional method, it is rather 2 to 3 times than the purchase of equipment. There has been a problem that fungi and bacteria, which often occur after a lapse of years, cannot be effectively prevented. Therefore, an object of the present invention is to provide an air conditioner capable of effectively exhibiting antifungal / antibacterial functions regardless of the passage of time.

[0004]

An air conditioner according to the present invention utilizes a heat source device or an electric heater which always operates together with a blower during a heating operation, and during a mold prevention operation, the heat source device or the electric heater is operated while the blower is stopped. It was designed to drive.

[0005]

In general, molds and bacteria can be completely killed by heating at a temperature of about 40 ° C. or higher for 1 hour or longer. The present invention uses a heating means for heating to remove mold, and by operating a heat source device or the like with the blower stopped, the ventilation passage in the indoor unit is maintained at a high temperature for a certain period of time, and generation of mold or the like occurs. It suppresses.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an essential part of an air conditioner embodying the present invention. A wireless remote controller 1 for controlling an indoor unit.
The cooling / heating switching unit 2 is provided with a mold removing switch along with the heating and cooling switches, and when the cooling / heating switching knob 3 selects the mold removing switch, the blower is not operated. Mold removal operation is performed to operate the heat source machine. In the figure, 4 is a run / stop button, which is used to reverse "run" and "stop" when pressed, 5 is a button for switching the wind direction of the flap in several stages, 6 is a display unit for degrees, time, etc., Reference numeral 7 is a transmitter.

FIG. 2 shows a comparison of the operations during the heating operation and the mold removal operation. First, in the heating operation shown in FIG. 2A, the cooling / heating switching knob 3 is set to "heating". If the operation / stop button 4 is pressed and "operation" is selected, the flap opens up to the position set in advance by the wind direction switching button 5 (step a), and then it is determined whether the room temperature is below the set value. When the temperature is equal to or less than the set value (step b), the heat source unit is activated (step c), and the blower starts operating (step d). Next, it is judged again whether or not the room temperature has exceeded the set value (step e). If it does not exceed the set value, the operation of the heat source machine is continued in the loop of e → c → d → e, and if it exceeds the set value, the heat source machine is stopped. Then, it waits for the room temperature to drop below the set value in the loop of e → f → e. Next, when the run / stop button 4 is pressed again and "Stop" is selected, the heat source unit and the blower are stopped (steps a and b) and the flap is closed (step c), as shown in FIG. , Heating operation ends.

When performing mold removal operation, the cooling / heating switching knob 3 is set to "mold removal" and the run / stop button 4 is pressed.
When is pressed, the flap closed state and blower stopped state (steps a and b) are first confirmed, then the heat source unit is started (Step c), and then the in-machine temperature is set, as shown in FIG. It is determined whether or not the value exceeds the value (step d), and if not exceeded, the operation of the heat source machine is continued in a loop of d → c → d, and if the internal temperature exceeds the set value, the heat source machine is stopped ( Step e). In this way, the temperature inside the machine is controlled so as to maintain a constant temperature (for example, 60 ° C.) (loop d → e → f → d), and a constant time (for example, 1 hour).
When is elapsed, the mold removing operation is finished (step f). When using an electric heater as a heat source instead of a heat exchanger that uses a heating medium such as hot water or chlorofluorocarbon, replace "heat source device" with "electric heater" in the above flowchart.
Should be replaced with Also, when using an electric heater for auxiliary heating together with a heat exchanger using a heat medium, the electric heater
A sufficiently high temperature can be obtained even if the mold removing operation is performed using only the

[0010]

The air conditioner with antifungal function according to the present invention is not a method of applying a paint containing an antifungal agent to the ventilation passage of an indoor unit as in the prior art, and therefore has the advantage that deterioration over time does not occur. Further, as described above, during the mold removal operation, the heat source device or the electric heater for the heating operation is used, and the heat source device or the electric heater is operated while the blower is stopped. Even if it is not equipped with, the ventilation passage in the indoor unit can be maintained at a temperature higher than that during heating operation, and the advantage that it is possible to prevent the generation of mold, bacteria, etc. with an extremely simple and inexpensive configuration is there.
