An oven appliance includes a cabinet that defines a chamber. A pair of doors is rotatably mounted to provide selective access to the chamber of the cabinet. The pair of doors is connected with a linkage assembly such that the doors rotate open and closed simultaneously. The linkage assembly includes a spur gear that engages another gear of the linkage assembly. The spur gear can hinder unwanted rotation of the pair of doors or compress the pair of doors against a seal.


Systems and methods for predicting and preventing a cabinet strike event in a washing machine appliance are provided. An exemplary method includes ramping a target speed of a motor from a first speed to a second speed over a ramping period. The method includes computing an average deviation of an observed speed of the motor from the target speed over the ramping period. The method includes computing an average power consumption by the motor over the ramping period. The method includes determining whether both the average deviation is greater than a first threshold value and the average power consumption is greater than a second threshold value. The method includes rebalancing the load if both the average deviation is greater than a first threshold value and the average power consumption is greater than a second threshold value. The method includes performing one or more standard operations if both conditions are not satisfied.

A vegetable bearing case comprising a solution bearing case (7) having a high-position solution inlet (1) and a low-position solution outlet (5) in an opposite arrangement. A switchback solution flow channel (2) is formed in the solution bearing case (7) at an area located between the solution inlet (1) and the solution outlet (5) by protruding flow deflecting partitions (3). An atomizer (6) is arranged in the solution flow channel (2). The solution flow channel (2) of the vegetable bearing case allows a nutrient solution to form within the entire vegetable bearing case one nutrient solution flow that flows through the entire vegetable bearing case, thus allowing for increased nutrient solution component uniformity within the vegetable bearing case, and facilitating balanced growth of a vegetable. In addition, the atomizer (6) atomizes the nutrient solution to allow the nutrient solution to vaporize evenly as a mist to the upper part space of the vegetable bearing case, thus facilitating absorption for the vegetable and satisfying requirements for nutritional substances for vegetable growth. Moreover, the volume of the nutrient solution that is atomized can be controlled via the atomizer (6) to control the growth rate of the vegetable, thus allowing the vegetable to be placed in corresponding states of normal growth, slowed growth, or zero growth, and extending the duration that the freshness of the vegetable is preserved.


A washing method of a washing machine and the washing machine. The washing machine comprises an outer tub (1), an inner tub (2), a pulsator (3) and a driving device. The driving device is a bi-rotor direct driving motor, comprising two rotors (4, 5) and one stator (6), wherein one of the rotors (4) is connected with a shaft (21) of the inner tub, and the other one (5) is connected with a shaft (31) of the pulsator. During washing, the impeller (3) and the inner tub (2) are respectively driven by the two rotors (4, 5) to rotate independently. During washing, the driving device drives the inner tub (2) and the impeller (3) to rotate reversely. The inner tub (2) and the pulsator (3) change the rotation direction in every rotation cycle. The driving device drives the inner tub (2) and the impeller (3) to change the rotation direction asynchronously so that the inner tub (2) and the impeller (3) rotate in the same direction during the time difference of reversing. The washing machine changes the washing water stream so as to relieve the intertwining of the laundry due to the synchronous reversing of the inner tub and the pulsator, therefore reducing the wear of the laundry. The application of the direct driving with two rotors, changing the conventional way of transmitting torque through gear reduction, reduces the energy loss caused by sub process energy transmission and meanwhile the noise is reduced.

A shielding device (50) capable of effectively preventing hot air from flowing to a storage compartment during defrosting and a refrigerator (1) comprising the shielding device (50). The shielding device (50) mainly comprises a blowing hood (51) roughly in the form of a cover, a drive shaft (54) extending to run through the blowing hood (51) and for driving the blowing hood (51), and a support base (52) for supporting the blowing hood (51) and the drive shaft (54). In addition, threads (54a) are formed on the peripheral side surface of the drive shaft (54), and the side surfaces of the threads (54a) tilt, to form an air passage, to discharge the attached moisture.


An air-conditioner air supply apparatus includes a non-annular cover body (101). A through-duct running through the non-annular cover body (101) is formed in the middle of the non-annular cover body (101). The non-annular cover body (101) has a front opening and a rear opening. The front opening forms a mixed air outlet (1016). The rear opening forms a non-heat-exchanged air inlet (1017). A non-annular main heat-exchanged air duct (1011) communicating an internal air duct (15) of an air-conditioner having the air-conditioner air supply apparatus with the through-duct is formed on a wall of the non-annular cover body (101). An airflow distribution assembly (18) for circumferentially distributing heat-exchanged air that enters the main heat-exchanged air duct (1011) from a heat exchanger of the air-conditioner is disposed in the non-annular main heat-exchanged air duct (1011). Also disclosed is an air-conditioner having the air-conditioner air supply apparatus.

Disclosed are a music washing machine and a control method thereof. The washing machine comprises a motor for introducing a washing water flow, the motor being connected to a control device for performing mutual conversion between a rotation and stopping ratio and/or rotation speed of the motor and a musical characteristic signal, so that the music emitted by an output device synchronizes with the rotation and stopping ratio and/or the rotation speed of the motor during working of the washing machine. By a conversion device of the washing machine, mutual conversion between the rotation and stopping ratio and/or rotation speed of the motor of the washing machine and the musical characteristic signal is performed, so that the output device emits music corresponding to the rotation and stopping ratio and/or the rotation speed of the motor during working of the washing machine. By the device and the method, the user can clearly know the water flow conduction inside the washing machine, and the flexibility of the motor is intuitively shown to the user, thereby achieving the effect of exhibiting the motor performance.
