Fig. 2 is a cross-sectional view showing a schematic configuration of an air conditioner according to the first embodiment. Fig. 3 is a flowchart showing a decontamination process of the air conditioner according to the first embodiment.
As shown in fig. 1 and 2, the air conditioner according to the present embodiment is, for example, a patio machine, and is a dedicated air conditioner installed in a factory or a kitchen. The air conditioner includes an indoor unit 1. The indoor unit 1 includes a casing 4 composed of a panel 2 and a cover 3. A blowing port 5 for blowing air cooled or heated into a room is formed at the front end of the panel 2, and a return port 6 for sucking air is formed at the rear end of the panel 2.
In the housing 4, a fan 7 driven by a motor, a heat exchanger 8 provided adjacent to the fan 7, and a water collection tray 9 located below the heat exchanger 8 and receiving condensed water dripping from the heat exchanger 8 are housed and mounted.
The indoor unit 1 is provided with a detergent box 12 connected to the shower device 10 via a detergent delivery pipe 11, and a pressure pump 13 for pressurizing the detergent in the detergent box 12. Specifically, a contaminant removal box 12 and a pressure pump 13 are provided in the front end portion of the panel 2 on the side of the air outlet 5 of the panel 2. Further, a detergent delivery pipe 11 is provided along the inside of the hood 3.
In the present embodiment, a detergent box (container portion) 12 contains a detergent for cleaning contaminants such as oil stains and dust.
In the present embodiment, the shower device 10 is attached to the cover 3 on the side (i.e., the front) of the heat exchanger 8 facing the fan 7. Therefore, compared with the case that the spraying device is positioned at the top of the heat exchanger, the direct spraying area is greatly increased, and the decontamination effect is greatly improved. The shower device 10 includes an atomizing unit 10a that atomizes the detergent supplied from the detergent box 12 and pressurized by the pressurizing pump 13, and a shower head 10b that showers the atomized detergent to the heat exchanger 8.
In the present embodiment, a small-sized pressurizing pump 13 and a portable contaminant removal box 12 provided in parallel with the air pump 13 are provided on the air outlet 5 side of the air conditioner, and the contaminant removal box 12 is detachably attached to the indoor unit 1, specifically, the air outlet 5 side of the air conditioner. Here, the pressure pump 13 may be a small-sized air pressure pump. The contaminant removal cartridge 12 is attached to the indoor unit 1 by, for example, a snap-in attachment method, a pop-up attachment method, or the like.
The detergent delivery pipe 11 has one end connected to the detergent box 12 and the other end connected to the shower device 10. In order to ensure the decontamination effect, the spray device 10 is arranged on the side of the heat exchanger 8 facing the fan 7.
Thus, when the air conditioner is normally operated, air is sucked into the casing from the return air inlet by the suction force generated by the operating fan, and is sent out to the room from the air supply outlet through the heat exchanger and the fan in sequence, thereby completing the whole air circulation process.
In the present embodiment, the indoor unit 1 further includes a control unit (decontamination control device) 15, a temperature sensor, and a humidity sensor. The control unit 15 is formed of, for example, an integrated circuit board, and is configured to be able to detect the power of the motor. Control lines for controlling the pressure pump 13 and the shower device 10 are connected to a control unit 15 of the air conditioner.
In the present embodiment, a display unit for prompting replacement of the detergent box 12 or replenishment of the detergent is further provided on the panel 2 of the air conditioner. Because the dirt removing box can be conveniently assembled and disassembled, when the display part sends a signal, the old dirt removing box is taken down, the dirt removing agent conveying pipe on the dirt removing box is pulled out, a new dirt removing box is replaced, and the dirt removing agent conveying pipe is inserted. Examples of the display unit include a lamp. That is, when the lamp is turned on, the display section emits a signal.
In addition, in this embodiment, the pressure pump is depressurized when the air conditioner is not cleaned, and at this time, the detergent in the spraying device and the detergent delivery pipe falls into the detergent box due to the gravity, thereby preventing the detergent from being left in the detergent delivery pipe all the time. Therefore, when the air conditioner for kitchen use is not cleaned, the dirt removing agent can fall back to the dirt removing agent box under the action of self gravity, so that the dirt removing agent conveying pipe is ensured to be smooth, and unnecessary waste of the dirt removing agent is avoided. Further, since the air conditioner is pressurized and sprayed by the pressurizing pump during cleaning, the air conditioner can atomize the dirt removing agent in cooperation with the shower head, and the air conditioner can efficiently and reliably remove dirt by greatly increasing the contact area with the contaminants such as oil stains and dust on the heat exchanger.
The present inventors have newly found that when contaminants such as oil stain or dust remaining on the heat exchanger become more, the wind resistance when the air sucked from the return air inlet by the suction force formed by the operating fan passes through the heat exchanger is significantly increased, so that the operation of the fan needs to be accelerated, resulting in an increase in the power of a motor driving the fan. Accordingly, the present inventors have newly found that whether or not the amount of contaminants such as oil stain and dust remaining on the heat exchanger is large can be checked by detecting the power of the motor by the control unit.
Based on the above-described new findings of the present inventors, the air conditioner according to the present embodiment performs the decontamination control method including the detection step and the decontamination step by the decontamination control device 15. In the detection step, when the power of the motor detected by the control unit 15 (indirectly and actually feeding back information on contaminants such as oil stain and dust on the heat exchanger) rises to a predetermined threshold value, it is determined that the heat exchanger 8 needs to be subjected to the decontamination process. Then, the control unit triggers a decontamination command, sends a signal to the booster pump 13 via the control line, operates the booster pump 13 to compress the decontamination agent, flows the compressed decontamination agent to the shower device 10 via the decontamination agent delivery pipe 11, atomizes the decontamination agent in the atomizing unit 10a of the shower device 10, and uniformly sprays the atomized decontamination agent from the shower head 10b of the shower device 10 onto the heat exchanger 8. Next, in the desmear step, desmear is performed to remove contaminants such as oil stains or dust on the heat exchanger. The decontamination step sequentially comprises a standing step, a refrigeration step, a heating step, an air supply step, a heating step and an air supply step.
Specifically, the detection step and the decontamination step are performed to sufficiently clean contaminants such as oil stains and dust adhering to the heat exchanger of the air conditioner. As an example, first, in the detection step, the power of the motor that drives the fan is detected by the detection unit (detection means), and when the detection unit detects that the power of the motor has risen to a predetermined threshold value, it is determined that the heat exchanger needs to be subjected to the stain removal processing, and the control unit issues a signal to start the stain removal step. At this time, the pressurizing pump is operated to compress the detergent, which flows to the spray device through the detergent delivery pipe.
Then, in the decontamination step, the operation modes of the air conditioner and the shower device are controlled to perform decontamination. That is, the spray device atomizes the detergent to spray the detergent in a mist form, and the spray time of the spray head is set to a predetermined time (for example, 1 minute); then, the stain remover is left on the heat exchanger for a predetermined time (for example, 20 minutes) to sufficiently contact and fuse the mist stain remover with contaminants such as oil stains or dust; subsequently, the cooling mode is operated for a predetermined time (for example, 15 minutes), and the heat exchanger is frosted (condensed); then, the heating mode is operated for a predetermined time (for example, 5 minutes) to defrost, and at this time, part of contaminants such as oil stains and dust and the detergent are discharged with the condensed water; then, the air blowing mode is operated for a predetermined time (for example, 5 minutes), and at this time, the remaining contaminants such as oil stains and dust, the stain remover, and the condensed water further flow down from the heat exchanger by the forced exhaust air; subsequently, the heating mode is operated again for a predetermined time (for example, 15 minutes), at which time the moisture remaining in the heat exchanger is evaporated to dryness; subsequently, the blower mode is operated again for a predetermined time (for example, 5 minutes), and the heat exchanger is returned to the temperature, at which time the entire decontamination process is completed. In addition, in the whole decontamination process, the air supply outlet is always in a closed state, the rotating speed of the motor in the refrigeration and heating modes is very low, and the decontamination button on the panel is in a normally-on state, so that the phenomenon that a user mistakenly thinks that the air conditioner is opened mistakenly is avoided.
That is, the decontamination control device 15 includes a detection unit (detection portion) 151 and a decontamination unit 152. The detection unit 151 is configured to perform the detection step described above. The decontamination unit 152 is configured to perform the decontamination process described above. Fig. 4 is a block diagram showing a schematic configuration of a decontamination control device for an air conditioner according to a first embodiment. As shown in fig. 4, the detection means 151 detects the power of the motor that drives the fan, and is configured to activate the soil removing means 152, specifically, to operate the pressurizing pump to pressurize the soil removing agent in the soil removing agent box and supply the soil removing agent to the shower device, when the power of the motor detected by the detection means is equal to or greater than a predetermined threshold value, the soil removing means 152 includes means 153 for spraying the soil removing agent to the heat exchanger for a predetermined time by the shower device, means 154 for leaving the soil removing agent to stand on the heat exchanger for a predetermined time, means 155 for operating the cooling mode for a predetermined time, means 156 for operating the heating mode for a predetermined time, means 157 for operating the blowing mode for a predetermined time, means 158 for operating the heating mode for a predetermined time again, and means 159 for operating the blowing mode for a predetermined time again.
In addition, the decontamination step can be cancelled through the control part at any time in the execution process, and the current decontamination step is quitted. Therefore, the decontamination step is time-consuming, the user can interrupt the decontamination operation at any time according to the condition of the user, and the daily use of the user is facilitated.
In addition, after the decontamination step is finished, the air conditioner is controlled to return to the working mode before the decontamination control method is operated, and a prompt signal for finishing the decontamination control method is sent to the control part.
The predetermined time in the step of spraying the stain removing agent to the heat exchanger for the predetermined time, the predetermined time in the step of leaving the stain removing agent on the heat exchanger for the predetermined time, the predetermined time in the step of operating the cooling mode for the predetermined time, the predetermined time in the step of operating the heating mode for the predetermined time, and the predetermined time in the step of operating the air blowing mode for the predetermined time may be adjusted by the control unit. Specifically, the respective step times can be adjusted at any time for different solvents and the like.
In the step of spraying the stain remover to the heat exchanger for a predetermined time, the degree of atomization of the stain remover sprayed by the spray device can be adjusted by the control unit. Specifically, the degree of atomization can be adjusted at any time for different solvents and the like.
Like this, through foretell detection procedure and scrubbing step, carry out effectual washing to pollutants such as the oil stain or dust that remain on heat exchanger, the user need not to look for professional after sales personnel and dismantles the machine and wash, only need according to the suggestion, key operation has guaranteed because the problem that refrigeration, the heating effect of air conditioner that the oil smoke arouses are bad and life can not obtain the assurance. Moreover, the air conditioner according to the present embodiment saves time, labor, and time.
Further, as a basis for determining the shortage of the detergent in the detergent box, when the detergent in the detergent box is used up, the shower head is not operated, and after the shower head stops operating for more than a predetermined time (for example, 30 seconds), the pressure pump stops operating, and a lamp indicating the shortage of the detergent flashes on the panel of the air conditioner to notify the user of the replenishment of the detergent.
In addition, the spray device is arranged on the side of the heat exchanger facing the fan, so that the spray area finally reaches 100%.
Further, by adopting the detection step and the decontamination step as described above, the heat exchanger can be thoroughly cleaned at one time by controlling the combination and timing of the cooling mode, the heating mode, and the blowing mode, and the problem of the secondary pollution source of the cleaning agent does not occur.
In addition, the power of the motor is detected to indirectly feed back the information of pollutants such as oil stains or dust on the heat exchanger, so that the information of the amount of the pollutants such as the oil stains or the dust can be fed back more clearly, and the method is more reliable than the method of presetting the cleaning time according to experience by a worker.
In addition, through the cooperation lectotype of force (forcing) pump and spray set for finally spray liquid and reach atomizing effect, increase the area of contact with pollutants such as oil stain or dust, can wash pollutants such as oil stain or dust more thoroughly.
In addition, by designing the detergent box to be easily detachable, when the shower head is not operated for a time exceeding a predetermined time (for example, 30 seconds), the operation of the pressure pump is stopped and the warning lamp is turned on and off to notify the user of replenishment of the detergent.
