  The invention according to claim 3 is characterized in that an auxiliary mechanism is provided to assist the deformation so that the volume of the inner container decreases.

  In the invention of claim 4, the auxiliary mechanism uses the buoyancy of water stored in the water purification chamber to lift the bottom wall portion of the inner container toward the top wall portion of the inner container. It is characterized by being.

  According to the first aspect of the present invention, since the inner container is provided with the expansion / contraction portion that increases or decreases the volume of the inner container, the water purification chamber can be enlarged by reducing the volume of the inner container, and the volume of the main body container is reduced. Without changing, more purified water can be stored in the water purification chamber.

  According to the invention of claim 2, since the expansion / contraction part is the bellows part formed in the peripheral wall part of the inner container, the configuration for increasing or decreasing the volume of the inner container can be made relatively simple.

  According to the invention of claim 3, since the auxiliary mechanism for assisting the deformation so as to reduce the volume of the inner container is provided, the reduction of the volume of the inner container is promoted to enlarge the water purification chamber. it can.

  According to invention of Claim 4, the said auxiliary mechanism is a float which pushes up the bottom wall part of the said inner container toward the top wall part of the said inner container using the buoyancy of the water stored in the said water purification chamber. Therefore, for example, compared with a configuration in which the bottom wall portion is pulled up from the raw water chamber side toward the top wall portion using a spring or the like, the inner container can be deformed so that the volume of the inner container is reduced with a relatively simple configuration.
