Dishwashing machine
This dishwasher utilizes a rod 58 whose upper end is linked to the proximal end of a rotary arm 10 , and compression springs 53 and 54 linked to the proximal end of the rotary arm 10 via the rod 58 . Thus, even if the compression springs 53 and 54 break, the elastic force of the compression springs 53 and 54 themselves is maintained, and furthermore, the compression springs 53 and 54 continue to be supported by the lower end of the rod 58 in a state of being positionally restricted with respect to a dishwasher main body 2 . This prevents a door 7 in an open state from suddenly falling.
1. A dishwasher, in which a washing chamber provided on the side of a dishwasher main body is opened and closed by moving a door up and down while rotating a rotary arm disposed on a side face of the door, the dishwasher comprising:
a spring unit detachable from the dishwasher main body, the spring unit integrally including a fixing member, a rod, and a compression spring; and
a female threaded member attached to the proximal end side of the rotary arm,
wherein a male threaded member is formed at the upper end of the rod, and the male threaded member is threaded into the female threaded member,
wherein the rod extends in a vertical direction and is linked at an upper end to the proximal end of the rotary arm,
wherein the compression spring extends in a vertical direction,
wherein the compression spring is disposed substantially parallel to the rod,
wherein an upper end of the compression spring is supported in a state of being restricted with respect to the dishwasher main body,
wherein a lower end of the compression spring is supported by a lower end of the rod,
wherein the fixing member supports the compression spring,
wherein the fixing member is removable from an upper opening at a top of a support tube arranged in the dishwasher main body in the vertical direction,
wherein the support tube is shaped such that a space inside thereof is pipe shaped, and
wherein a cap, configured to open/close the opening of the support tube, is fixed to the opening of the support tube.
2. The dishwasher according to claim 1 , further comprising a female threaded member attached to the proximal end side of the rotary arm,
wherein a male threaded member is formed at the upper end of the rod, and the male threaded member is threaded into the female threaded member.
3. The dishwasher according to claim 2 , further comprising a guide member that accommodates the compression spring.
4. The dishwasher according to claim 1 , further comprising a guide member that accommodates the compression spring.
5. The dishwasher according to claim 1 , further comprising a guide member that accommodates the compression spring.
6. A dishwasher, in which a washing chamber provided on the side of a dishwasher main body is opened and closed by moving a door up and down while rotating a rotary arm disposed on a side face of the door, the dishwasher comprising:
a spring unit detachable from the dishwasher main body, the spring unit integrally including a fixing member, a rod, and a compression spring,
wherein the rod extends in a vertical direction and is linked at an upper end to the proximal end of the rotary arm,
wherein the compression spring extends in a vertical direction,
wherein the compression spring is disposed substantially parallel to the rod,
wherein an upper end of the compression spring is supported in a state of being restricted with respect to the dishwasher main body,
wherein a lower end is supported by the lower end of the rod,
wherein the fixing member supports the compression spring,
wherein the fixing member is removable from an upper opening of a support tube arranged in the dishwasher main body in the vertical direction,
wherein a guide cylinder accommodates the compression springs,
wherein the guide cylinder is linked with the fixing member by way of a shaft pin passing through two shaft holes of the guide cylinder and two shaft holes of the fixing member, and
wherein the assembly of the guide cylinder and the fixing member is further accommodated in the support tube.
