7. The laundry treating apparatus according to claim 6, wherein the first detergent supply module further includes:

at least one pump connection conduit to connect an interior of the accommodation frame with the at least one detergent pump; and

at least one detergent supply conduit to guide the first detergent discharged from the at least one detergent pump to the second detergent storage module, wherein the at least one container includes at least one detergent discharge conduit to discharge the first detergent stored in the at least one container to the accommodation frame when the at least one container is inserted into the accommodation frame.

8. The laundry treating apparatus according to claim 1, wherein the at least one container is fixed to the module door, and wherein the at least one detergent pump is fixed to the at least one container.

9. The laundry treating apparatus according to claim 8, wherein the first detergent supply module further includes:

at least one pump connection conduit that allows the container to communicate with the at least one detergent pump therethrough; and

at least one detergent supply conduit to guide the first detergent discharged from the at least one detergent pump to the tub.

10. The laundry treating apparatus according to claim 8, further including:

a second detergent storage module positioned above an upper portion of the introduction port to communicate with the tub and store a second detergent therein; and

a water supply device to supply washing water to the second detergent storage module to introduce the second detergent stored in the second detergent storage module into the tub.

11. The laundry treating apparatus according to claim 10, wherein the first detergent supply module further includes:

at least one pump connection conduit that allows the at least one container to communicate with the at least one detergent pump therethrough; and

at least one detergent supply conduit to guide the first detergent discharged from the at least one detergent pump to the second detergent storage module.

12. The laundry treating apparatus according to claim 1, wherein the at least one container further includes:
