- the hook 510 is provided on the upper and lower surfaces of the cartridge 420 frame, and is fitted and coupled to the fastening hole 520 formed in the housing.
- the spring 530 is coupled between one end of the hook 510 and the upper and lower surfaces of the cartridge 420 , and elastic force is applied in the direction of pushing the hook 510 .
- the hook 510 overcomes the elastic force of the spring 530 due to the pressing pressure and maintains a horizontal state. In this state, the user inserts the cartridge 420 into the through hole 412 of the housing 410 , couples it, and releases the press of the hook 510 .
- the hook When the press of the hook is released, the hook rotates like a seesaw motion with the stopping jaw 521 as a point by the elastic force of the compression spring 530, and the rotated hook is caught by the stopping jaw 521 of the fastening hole. , the cartridge can be easily coupled to the housing.
- the cartridge can be easily separated by proceeding in the opposite direction to the above coupling sequence.
- the cartridge 420 fastened by the detachable means 500 may generate noise due to vibrations generated in the driving of the heat pump type cold/hot air dryer. This embodiment describes a configuration that can minimize the noise. do.
- the noise of the detachable means is most generated at the contact portion between the hook 510 and the locking jaw 521.
- the locking jaw 521 is characterized in that a rubber composition for damping vibration is coated.
- the rubber composition is based on 100 parts by weight of the acrylic rubber, 10 to 20 parts by weight of carbon black having a particle size of 20 to 45 (nm), 5 to 7 parts by weight of an accelerator, 4 to 5 parts by weight of an activator, 1 to 4 parts by weight of an antioxidant , 4 to 5 parts by weight of a vulcanization aid, 3 to 7 parts by weight of a peroxide crosslinking agent, and 3 to 6 parts by weight of paraffin oil.
- the rubber composition as described above has excellent mechanical properties such as tensile strength and permanent compression set in addition to high heat resistance, minimizes natural frequency change at high temperature, improves durability, and has excellent vibration damping performance.
