Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
174 words
An acarid extermination device comprising a base body movable along the subject of extermination, a far-infrared ray emission unit, mounted on said base body, for emitting far-infrared rays toward said subject of extermination, and a blower unit for cooling said heated subject of extermination, said blower unit being controlled by a temperature control unit so that said subject of extermination is not heated above an established temperature, wherein said temperature control unit is provided with a radiant temperature sensor to detect the surface temperature of said subject of extermination, a thermometer to indicate said temperature detected, a temperature setting circuit, and a temperature control circuit which makes a comparison between the established input signal from said temperature setting circuit and the input signal of said detected temperature from said radiant temperature sensor, and, in the event that said input signal of the detected temperature is higher than said established input signal, issues a control signal to terminate the operation of said far-infrared ray emitting unit and another control signal to operate said blower unit.
Claim 2
Dependent Claim
174 words
An acarid extermination device comprising a base body movable along the subject of extermination, a far-infrared ray emission unit, mounted on said base body, for emitting far-infrared rays toward said subject of extermination, and a blower unit for cooling said heated subject of extermination, said blower unit being controlled by a temperature control unit so that said subject of extermination is not heated above an established temperature, wherein said temperature control unit is provided with a radiant temperature sensor to detect the surface temperature of said subject of extermination, a thermometer to indicate said temperature detected, a temperature setting circuit, and a temperature control circuit which makes a comparison between the established input signal from said temperature setting circuit and the input signal of said detected temperature from said radiant temperature sensor, and, in the event that said input signal of the detected temperature is higher than said established input signal, issues a control signal to terminate the operation of said far-infrared ray emitting unit and another control signal to operate said blower unit.
Claim 3
Dependent Claim
36 words
An acarid exterminating device as claimed in claim 1, wherein said temperature control unit is provided with an alarm means for warning that said detected temperature of the subject of extermination has exceeded the established temperature.
