An oven device defines a vertical direction, a transverse direction, and a horizontal direction. The vertical direction is perpendicular to the transverse and horizontal directions. The oven device comprises a housing extending in the transverse direction between a first side part and a second side part. The housing also extends in the vertical direction between the top part and the bottom part. The housing defines an upper cooking cavity located adjacent to the top part of the housing and a lower cooking cavity located adjacent to the lower part of the housing. The oven device also comprises: a single heat source in thermal communication with the external environment around the oven device by means of natural convection; and a fan, which is operable to enable direct thermal communication between the single heating part and one or both of the upper cooking cavity and the lower cooking cavity by means of forced convection.
A: A simulation electronic candle, comprising a casing (1), a flame piece (21) provided in an opening at the top of the casing via a transverse support rod (23), a light emitting element (4) provided on one side of the opening and a disturbance device (3) provided in the casing; the flame piece is connected crosswise to the support rod through a vertical swing link (22), and the upper portion of the swing link extends into the lower portion of the flame piece; part of the upper and the lower portions of the flame piece is positioned above the opening; the light projection direction of the light emitting element intersects with the surface of the flame piece. The static design of the improved flame piece assembly makes the flame piece exhibit unique appearance features in the shape of a candlewick, thus having better static simulation effect.
B: A novel air oven, comprising a housing (1), a liner (3) disposed in the housing (1) and having a main cooking cavity (2), and at least one vertical partition plate (5) detachably arranged in the liner (3). The vertical partition plate (5) partitions the main cooking cavity (2) into two or more sub-cooking cavities (4) arranged left and right; at least one heater (6) is disposed in each sub-cooking cavity (4); the upper part of each sub-cooking cavity (4) is provided with a fan (7) located in the housing (1) and communicated with the corresponding sub-cooking cavity (4). With the present air oven, the main cooking cavity (2) can be partitioned, by means of the vertical partition plate (5), into two or more sub-cooking cavities (4) arranged left and right, so that the air oven can be used to cook two or more food ingredients requiring different heating temperatures and durations.
C: An induction dryer device having a bearing system, comprising a casing. A drum is positioned inside the casing, and can rotate about an axis inside the casing. The induction dryer device further comprises an induction heating element and a support assembly. The support assembly is positioned adjacent to the drum inside the casing and comprises a plate. The induction heating element is positioned on the plate. A bearing is mounted to the plate. When the drum rotates about the axis, the bearing contacts the drum such that the bearing spaces the plate apart from the drum in a radial direction perpendicular to the axis.
D: A wall-mounted air conditioner indoor unit, comprising: a machine shell (10), and at least one cross-flow fan (20) and an evaporator (30) which are provided in the machine shell (10), wherein the machine shell (10) is provided with an air inlet (11) and an air outlet (12), and two independent wind deflectors (131, 132) are provided at the air outlet (12), each of the wind deflectors being configured to be controlled to pivot around a rotating shaft thereof; the evaporator (30) is arranged on the at least one cross-flow fan in a covering mode and comprises a first heat exchange section (31), a second heat exchange section (32) and a third heat exchange section (33) which are sequentially connected from back to front; and the third heat exchange section (33) is a V-shaped heat exchange section which extends gradually and obliquely in the direction opposite to the outer side of the at least one cross-flow fan (20) from the two transverse ends of the machine shell (10) to the middle thereof or is a curved surface heat exchange section which gradually protrudes and extends in a bending mode in the direction towards the outer side. The rotating shafts of the two wind deflectors (131, 132) extend obliquely upwards from the two transverse side parts of the machine shell (10) to the middle part of the machine shell respectively, so that the projection of the rotating shafts of the two wind deflectors (131, 132) in the vertical plane perpendicular to the front and back direction form an inverted V shape which inclines gradually upwards from the two transverse ends of the machine shell (10) to the middle thereof.
