The liquid detergent is put into 123 and the liquid finish is put into the right liquid finish container 124, but both of them are narrow containers, and may be accidentally put into one of them.

  Further, for example, when the detergent container 121 is arranged on the left side of the washing machine and the right side of the washing machine is in contact with the wall, it can be inserted from both the left and right sides, but 90% of people have the right hand as the dominant hand. It will be inserted from the right side, and it may enter in one side by mistake.

  For example, if the liquid detergent to be put in the left part enters the liquid finish agent storage part 124 in the right part even a little, the liquid detergent is put into the water tank together with the liquid finish agent during the rinsing process, and rinsed. There was a problem that performance was affected. On the contrary, if the liquid finishing agent put in the right part enters the liquid detergent container 123 on the left part even a little, the effect of the detergent is lost at the time of washing.

  The present invention solves the above-mentioned conventional problems, and by improving the operability at the time of charging a liquid detergent, a liquid bleach and a liquid finish, each of them does not mix and reliably exhibits a predetermined effect. The purpose is to let you.

  In order to achieve the above object, a drum type washing machine of the present invention comprises a rotating drum having a rotation center axis in a substantially horizontal direction or an inclined direction, a water tank containing the rotating drum, a powder detergent container, a liquid finish or Detergent storage container provided with a first storage part for storing liquid detergent, and a second storage part for storing liquid finish or liquid detergent, a water injection lid for injecting water into the detergent storage container, and the detergent storage A detergent charging unit frame that constitutes a space for accommodating the container in a freely drawable manner, and a water tank water supply path that communicates the detergent charging unit frame and the water tank, and stores the powder detergent in the rear part of the detergent container. A second storage part is provided on the front side of the powder detergent storage part, the first storage part is provided on the front side of the second storage part, and the first storage part and the second storage part are provided. The partition wall with the housing part of the front It is obtained by inclined towards the outflow port formed in the rear wall portion of the second housing portion.

  As a result, it becomes easy to put the liquid agent from the upper side to the liquid detergent container and the liquid finish container, and each liquid agent is not erroneously entered into the other container, and is poured into the liquid detergent container. Since the liquid agent smoothly enters the water tank toward the liquid detergent outlet, the predetermined effect of each liquid agent can be surely exhibited.

  The drum type washing machine provided with the detergent container of the present invention can exhibit a predetermined effect without mixing the liquid detergent or liquid bleaching agent and the liquid finishing agent at the time of charging.
