It is a figure showing composition of a washing machine concerning an embodiment of the present invention. It is a control flow diagram of the washing machine according to the embodiment of the present invention.

  FIG. 1 is a view showing a configuration of a washing machine according to an embodiment of the present invention.

  The washing machine according to the embodiment of the present invention is configured around the washing drum 11. The washing machine is provided with a drum inlet 11s for taking in air from the outside and an outlet 11e for discharging air in the washing drum 11, with the washing drum 11 as a center. Furthermore, the drum air inlet 11s is connected to an air combustion passage 12 that burns air taken from the outside. The air combustion passage 12 is provided with a combustion unit 13 for burning the air in the air combustion passage 12. In addition, the air combustion passage 12 is provided with an intake port 14 for taking in air from the outside. An exhaust passage 15 for exhausting the air in the washing drum 11 is connected to the drum exhaust port 11 e. In the exhaust passage 15, a thermometer 20 for measuring the temperature of the air exhausted from the inside of the washing drum is disposed. At the end of the exhaust path 15, there is an exhaust port 16 leading to the outside, and a fan 17 is provided in front of it.

  The washing drum has a rotating shaft 11c, and rotates around the rotating shaft 11c. The rotation is performed in the pest control mode, at the time of washing, at the time of rinsing, at the time of drying, or the like. As a result, the laundry put in the washing drum 11 can be rotated by the rotation of the washing drum 11 to wash away dirt, dust, etc. of the laundry.

  The drum intake port 11s of the washing drum 11 is provided with an air combustion path 12 in contact with the combustion unit 13, and an intake port 14 for taking in air from the outside is disposed. The combustion of the air by the combustion unit 13 may be any one as long as it heats the air in a short time. For example, the air may be burned by burning a gas. Alternatively, the air may be burned through electricity such as a heating wire. Since it is necessary to heat a large amount of air in a short time depending on the size of the washing drum 11, in the current technology, it is efficient to carry out by burning the gas.

  An exhaust passage 15 is connected to the drum exhaust port 11e of the washing drum 11, and a fan 17 is disposed in front of the exhaust port 16 for exhausting air to the outside. The fan 17 may be provided between the washing drum 11 and the exhaust port 16 and may be disposed so as to exhaust air to the outside efficiently. The fan 17 can take in air from the intake port 14, take in the burned air into the washing drum 11, and exhaust the air through the exhaust passage 15. Since the fan 17 is provided on the exhaust port 16 side, a constant flow of air can be created from the intake port 14 to the exhaust port 16, and the air in the washing drum 11 always becomes fresh heated air, and the laundry Can kill the pests hidden in Further, a thermometer 20 is disposed between the washing drum 11 and the exhaust port 16. The thermometer 20 is for measuring the temperature of the air exhausted from the washing drum 11.

  Next, the operation of the present embodiment will be described according to the flowchart of FIG. FIG. 2 is a control flow diagram of the washing machine according to the embodiment of the present invention. In the washing machine according to the embodiment, the pest control mode can be selected before the washing mode (including the washing process, the rinsing process, the dewatering process, the drying process, and the like). When each step of the pest control mode is completed, the process proceeds to the washing step which is the first step of the washing mode. The washing machine is provided with a pest control mode selection button for pest control in the pest control mode. Therefore, without the pest control mode, it is possible to select and execute the washing process, the rinsing process, the dewatering process, the drying process and the like only in the washing mode.

  In the pest control mode, the fan 17 is driven to take in air into the washing drum 11 (step S101). When the fan 17 is driven, air is taken in from the air inlet 14, passes through the air combustion path 12 and the drum air inlet 11 s, and air is taken into the washing drum 11. Further, the air in the washing drum 11 passes through the exhaust passage 15 and is exhausted from the exhaust port 16 to the outside.

  Next, the washing drum 11 containing the laundry is rotated (step S102). Next, the combustion unit 13 is driven to burn the air taken into the air combustion passage 12 from the intake port 14 (step S103). At this time, the air burned is at a temperature of 65 degrees or more. For example, the air is preferably 70 to 100 degrees. The air always flows from the intake port to the air combustion path 12, the exhaust path 15, and the exhaust port 16 by the drive of the fan 17. As the washing drum 11 rotates while the burned air enters from the intake port 14, the hot air uniformly contacts the laundry.

  Because the temperature of the laundry changes depending on the season and room temperature, the air that has been burned warms the laundry, and when it is exhausted, the temperature when it comes in from the air combustion path 12 or the drum intake 11s It is exhausted in the low state too. Here, the temperature of the air exhausted is measured by a thermometer 20 provided in the vicinity of the drum exhaust port 11e, and comparison is made with a set predetermined temperature (step 104). The air which has uniformly touched the laundry by the rotation of the washing drum 11 warms the laundry rapidly, and when the temperature of the laundry and the air become equal, the air is exhausted without being deprived of heat energy. As a result, when the temperature of the thermometer 20 provided in the vicinity of the drum outlet 11e reaches a predetermined temperature, the rotation of the fan 17, the combustion unit 13 and the drum can be stopped (step S105). The driving time of the pest control mode is shorter than the driving time of the drying process. In particular, the driving time of the pest control mode is preferably shorter than the driving time of the drying step.

Here, the predetermined temperature is a temperature at which a pest lurking in the laundry is killed, and may be 60 to 75 degrees, preferably 65 degrees or more. In this way, not only the surface of the laundry but also the underlying pests in the back of the fiber are killed by the heated air that has been burned, and the dead pests are further exhausted by the rotation of the washing drum 11 and the exhaust by the fan. Because the centrifugal force discharges the insect pests dropped from the fibers of the laundry, the possibility of the insect pests remaining in the washing drum 11 is reduced . Also, since washing and drying are performed in the washing drum 11 in a more clean state as described above, it is possible to better control insects from the laundry. As a matter of course, it is also possible to continue for a predetermined time which is determined in advance without ending the pest control mode immediately after the temperature reaches 65 degrees.

  By the time the temperature of the air exhausted from the washing drum 11 reaches 65 degrees, for example, it takes about 3 to 4 minutes. This is because the air burned in the air combustion path 12 is already high temperature air of 100 ° C. or more, and a large amount of air can be fed in at one time.
