A dishwasher is disclosed that may include a washing chamber and a detergent compartment. The detergent compartment may include an opening facing the washing chamber. The dishwasher may further include two or more static nozzle openings arranged in the washing chamber. Each of the two or more static nozzle openings may be configured to spray water into the detergent compartment, via the opening, during operation of the dishwasher.

Proposed is ultrasonic spoon washing apparatus and method, which use ultrasonic waves generated by one or more ultrasonic oscillators provided on a vertical side wall of polygonal surfaces of a wash tub, so that spoons contained in a spoon support part rotating forward/in reverse may very efficiently and conveniently be washed while the number of revolutions changes for each washing stage, the apparatus including: a frame body; the wash tub mounted inside the frame body; one or more ultrasonic oscillators provided on an outer side of the vertical side wall; a forward/reverse rotation support part including a support shaft and a rotation support pipe; a spoon support part including a holder and a spoon accommodation container; a rinsing water supply part configured to spray the rinsing water together with a rinsing aid; and a wastewater and foreign material discharge part configured to discharge, to the outside, wastewater and foreign materials.

A filter structure of a dishwasher and a dishwasher, wherein the filter structure of the dishwasher comprises a filter screen, the filter screen comprises several first filter ribs and several second filter ribs, and the second filter ribs and the first filter ribs are arranged to cross each other so as to form a mesh structure. The filter screen of the filter structure is a mesh structure, which does not need post-perforation, thereby saving on fabrication costs. The filter screen comprises a mesh structure formed by the second filter ribs and the first filter ribs being arranged to cross each other. Not only do the second filter ribs and the first filter ribs enhance the strength of the filter screen, but the mesh structure also prevents the occurrence of a situation in which filter pores of a metal filter screen are blocked by washing impurities.

A chair device, a mattress device, and a propping device are provided. The chair device includes a support stand, a seat module disposed above the support stand, a connection module disposed at one side of the seat module, a back support module connected to the connection module and disposed at one side of the seat module, a first pressure adjustment module disposed in the seat module, a second pressure adjustment module disposed in the back support module, a first pressure sensing module disposed in the seat module, a second pressure sensing module disposed in the back support module, and a control module. The control module adjusts the first pressure adjustment module according to first sensed pressure signals from the first pressure sensing module, and adjusts the second pressure adjustment module according to second sensed pressure signals from the second pressure sensing module.
