A microwave appliance, as provided herein, may include an outer casing, an inner liner, a door, and an air handler. The outer casing may define an air inlet above a cooktop appliance. The outer casing may extend in a lateral direction between a first side end and a second side end. The inner casing may define a cooking chamber. The door may include a peripheral frame and a front window bounded by the peripheral frame. The peripheral frame may define an air outlet downstream from the air inlet and below the front window along the vertical direction. The air handler may be mounted within the outer casing in fluid communication between the air inlet and the air outlet to motivate an airflow therethrough. The air outlet may define an airflow curtain path extending outward from the outer casing in front of the door.

The present application discloses a cooking device, which includes a cabinet; the cabinet includes an inner cavity, a first heating assembly and a second heating assembly; the inner cavity is provided with a cooking chamber, as well as a first side wall and a second side wall that are arranged opposite to each other, the first side wall is provided with a first ventilation structure, and the second side wall is provided with a second ventilation structure; the first heating assembly is arranged outside the inner cavity and arranged corresponding to the first ventilation structure, and is configured to circularly heat air in the cooking chamber; the second heating assembly is arranged outside the inner cavity and arranged corresponding to the second ventilation structure, and is configured to circularly heat the air in the cooking chamber.

A method of detecting anomalies of a fan within an appliance includes receiving, at a service computer and/or remote server, data indicative of usage of the fan, analyzing the data indicative of usage of the fan with a machine learning model on the service computer and/or remote server, and flagging the fan for replacement when the machine learning model detects an anomaly in the data indicative of usage of the fan.

The present disclosure relates to a drawer-type microwave oven comprising a cooker body, a door, a first slide rail, a second slide rail, a driving motor, a magnetron and a first fan. The cooker body includes a housing and a cooking cavity provided within the housing. The magnetron and the first fan are provided in the third spacing region, the housing is provided with an air inlet mesh that is in communication with the third spacing region. Cold air entering from the air inlet mesh is guided to flow through the magnetron and the driving motor in sequence when the first fan works. When the drawer-type microwave oven works, the first fan draws the cold air into the third spacing region through the air inlet mesh, and the cold air flows through the magnetron and the driving motor in sequence, which can dissipate the heat from the driving motor well, thereby reducing the temperature of the driving motor and ensuring the long-term normal operation of the driving motor and prolonging its service life.

A heating cooking apparatus includes a heating chamber, a first detection unit, and a first interposed member. The heating chamber accommodates an object to be heated. The first detection unit is spaced apart from the heating chamber and detects sound in the heating chamber. The first interposed member is interposed between the heating chamber and the first detection unit and extends from the first detection unit toward the heating chamber. The first interposed member includes a through hole that passes the sound.

A cooking appliance with microwave heating function is disclosed, which includes a cooker body 10, a first fan 20, a second fan 30, a variable frequency power supply 40 and a magnetron 50. When the cooking appliance with microwave heating function works, on the one hand, the first fan 20 draws in the air outside the cooker body 10 through the side air inlet mesh 1111 and the bottom air inlet mesh 1131, and blows it to the variable frequency power supply 40 for heat dissipation. The large amount of air entering has a good heat dissipation effect on the variable frequency power supply 40. The second fan 30 draws in the air outside the cooker body 10 through the bottom air inlet mesh 1131 or the side air inlet mesh 1111, and blows it to the magnetron 50 for heat dissipation, which achieves a good heat dissipation effect on the magnetron 50. On the other hand, the plane where the air inlet of the first fan 20 is located is arranged obliquely with respect to the bottom cover plate 113, thus compared with a horizontal arrangement, the occupation space of the first fan 20 in a horizontal direction can be reduced to a certain extent, which can increase the volume of the cooking cavity while reducing the heat dissipation effect.

A household oven includes a cooking chamber (6), a light source mount (31), an LED light source (20) arranged on the light source mount (31) to shine light into THE cooking chamber (6), a heat sink (16), and a heat pipe (15) thermally coupling the LED light source (20) to the heat sink (15). This design allows to carry off heat from the LED light source (20).

Methods and apparatuses for drying, especially cannabis, are provided. One of the provided methods includes: heating the cannabis in a cavity of a variable frequency microwave oven using at least two different frequencies; measuring temperature of at least 1 cm square of the cannabis at different times during the heating; and controlling the heating based on the temperature measured so that the cannabis is kept for at least 20 minutes at temperatures above 30° C. and below 100° C.

An oven includes a housing that defines a cooking space and that includes an upper frame defining an upper wall facing the cooking space, a heating unit disposed at the upper frame and configured to transfer heat to the cooking space, an antenna disposed at the upper frame and configured to emit, toward the cooking space, radio waves transmitted from a radio wave generator that is electrically connected to an external power source, and a forming part that protrudes upward from the upper frame and accommodates the antenna therein. The forming part covers the antenna from the cooking space.

A solid-state radio frequency (SSRF) water heating apparatus is disclosed. In embodiments, the SSRF water heater includes a water tank, SSRF generator array and RF sensors enclosed within an RF-shielded cage. The SSRF array synthesizes RF signals in the microwave range and transmits the RF energy through the water tank, exciting and heating the water molecules without direct contact. The RF sensors at the opposite end of the tank sense residual RF energy not absorbed by the water. Control processors regulate the generation and transmission of the RF energy based on the sensed residual energy. The heated water and/or generated steam is piped to hot water dispensers, beverage makers, or steam ovens.
