Definitions

  • the present disclosure relates to the field of washing technologies, and more particularly, to a dispenser and a washing appliance.
  • dispensers are usually used to dispense washing substances, such as powders, liquids, or tablets, into the dishwashers.
  • the powders, liquids, or tablets dissolve to form detergents for washing dishes.
  • a washing substance in a dispenser may fail to fall into the dishwasher totally.
  • a powder washing substance may stick to the dispenser.
  • Implementations of the present disclosure provide a dispenser and a washing appliance.
  • the dispenser according to the implementations of the present disclosure is used in a washing appliance.
  • the dispenser includes: a main body having an accommodating chamber and a water inlet channel in communication with the accommodating chamber, wherein the accommodating chamber has an opening located at a top portion of the main body, the opening allows a detergent to be added and allows a liquid injected from the water inlet channel into the accommodating chamber to overflow to be discharged to an outside of the dispenser; and a cover body configured to selectively open or close the opening.
  • the dispenser with the configuration of the water inlet channel and the accommodating chamber of the dispenser, water is allowed to flow into the accommodating chamber through the water inlet channel, and further, since the opening is located at the top portion of the main body, it is difficult for the water in the accommodating chamber to flow out of the dispenser, so that there is enough water in the accommodating chamber to dissolve a detergent. Therefore, the detergent can be fully mixed with the water before overflowing through the opening to the outside of the dispenser.
  • Such a structure is simple and easy to implement.
  • the washing appliance includes the dispenser as described above.
  • the washing appliance with the configuration of the water inlet channel and the accommodating chamber of the dispenser, water is allowed to flow into the accommodating chamber through the water inlet channel, and further, since the opening is located at the top portion of the main body, it is difficult for the water in the accommodating chamber to flow out of the dispenser, so that there is enough water in the accommodating chamber to dissolve a detergent.

  • the top of the first plate 112 is higher than the top of the second plate 113, water in the first accommodating chamber 1111 and water in the second accommodating chamber 1112 can be prevented from being exchanged with each other. That is, if a height of the top of the first plate 112 is smaller than a height of the top of the second plate 113, when water is fed into the first accommodating chamber 1111 from the water inlet channel 60, the water in the first accommodating chamber 1111 may flow from the first plate 112 into the second accommodating chamber 1112, rather than flowing from the second plate 113 into the washing chamber 201 of the washing appliance 1000. Therefore, the top of the first plate 112 being higher than the top of the second plate 113 can prevent the water in the first accommodating chamber 1111 from flowing into the second accommodating chamber 1112.
  • the first plate 112 is perpendicular to the mounting plate 14.
