  • Publication number: 20250025015
    Abstract: A dish washer includes a heater for regenerating a moisture absorbent. A portion of the heater is received in a heater receiving portion, and the remaining portion thereof is received in an air introduction space under a moisture absorbent receiving space, such that air flow sufficiently heated by the heater may flow into the air introduction space, thereby reducing a possibility of local variation in the regeneration of the moisture absorbent, and the moisture absorbent is directly heated by radiant heat of the heater received in the air introduction space to improve heat emission efficiency and energy efficiency of the heater.

  • Publication number: 20240423441
    Abstract: A dish washer has a discharge flow path configured to carry air flow having passed through a moisture absorbent. The discharge flow path is defined between a cover of a moisture absorbent receiving space of a main housing and the moisture absorbent. The discharge flow path is configured to reduce non-uniformity in resistance against air flow having passed through the moisture absorbent inside the main housing and local non-uniformity in a moisture absorption amount to improve moisture absorption efficiency.
