Edge opening is located at the rocker end inside the knob cover and the opening is symmetrical to the balance slot in the center of the cylinder. The balance slot is against the rocker knob cover end for limit while one inner end of the balance slot is equipped with limit plate. The knob cover is driven by knob to realize rocking between knob cover and rocker.

A frying apparatus includes a main body, a frying vat, a fry basket and a detection module. The frying vat located on the main body has a first polar plate. The fry basket includes a basket frame and a second polar plate. When the fry basket is positioned inside the frying vat, the second polar plate is parallel to and separated from the first polar plate to form an equivalent capacitor. The detection module is electrically connected with the first and second polar plates. When the first and second polar plates are dipped in the oil contained inside the frying vat, the detection module detects a capacitance of the equivalent capacitor, then a corresponding dielectric constant of the oil is obtained by evaluating the capacitance and at least one coupling condition, and further a corresponding total polar material concentration of the oil with respect to the dielectric constant can be deduced.

A combined rotisserie oven, range and fryer included in a single device having an oven housing with an oven compartment, a plurality of oven, range and fryer heating elements. A removable rotisserie spit is reversibly engaged with and driven by a rotisserie spit gear disposed within the oven compartment. A range top with a plurality of range burners is disposed on the oven compartment. A grill is also disposed upon the range top. A deep fryer pan is disposed within a fryer pan chamber of the oven housing. A mesh wired deep fryer basket having a handle fits within the deep fryer pan, while a lid fits over each of the deep fryer pan and the deep fryer basket. A removable deep fryer control panel is removably engaged with a master control panel. The removable deep fryer control panel includes a deep fryer heating element and a thermostat.

There is provided an apparatus (200, 300, 400, 500) comprising: a container (210, 310, 410, 510) configured to receive a food stuff, a base unit (220, 320, 420, 520) comprising a mounting member and a plurality of outer supporting members (324, 424, 524), a weight sensing unit (230, 330, 430, 530) configured to measure a weight of the food stuff contained in the container, and a connection assembly (240, 340, 440, 540) arranged between the container and the base unit. The weight sensing unit comprises a plurality of strain gauge load sensors arranged at the mounting member of the base unit, and the connection assembly is configured to provide a flexible and insulating connection between the container and the base unit so as to counteract thermal strain interference at the weight sensing unit and to reduce heat transfer between the container and the weight sensing unit.

A food preparation device may include a radio frequency (RF) capacitive heating source, a liquid temperature control assembly, a cooking controller operably coupled to the RF capacitive heating source and the liquid temperature control assembly, a basin configured to contain a liquid and receive a food product, and a lid hingedly attached to the basin. The lid may be configured to have a function related to a selected food preparation program. The RF capacitive heating source may include a ground plate and an anode or High Voltage (HV) plate disposed on opposing surfaces of the basin.

The present invention relates to manufacturing of kitchen appliances, and particularly to air fryer, comprising fryer body, liner, frying basket provided within the liner, electrical heating tube arranged above the frying basket and fan located above the heating tube. Side wall of the frying basket is thin plate and bottom of the frying basket is grid. Air channel is provided between the liner and the frying basket. Swirl guide cylinder is provided externally at the bottom of the frying basket and is connected with the side wall of the frying basket. Air inlets for forming rotary air flow are opened on the bottom of the swirl guide cylinder. The air inlets divert the air flow in a same direction and form a swirl. With such configuration, the frying basket is simple in structure, the liner is easy to manufacture and clean, and the frying basket is better supported.

A food preparation device may include a radio frequency (RF) capacitive heating source, a cooking controller operably coupled to the RF capacitive heating source to selectively distribute power to the RF capacitive heating source, and a hot oil basin. The RF capacitive heating source may include a ground plate and an anode plate disposed on opposing sides of the hot oil basin.

The present invention relates to the technical field of household appliances. Provided is a multifunctional air fryer. In the air fryer, when a heating tube of a heating assembly faces downwards, a pot such as a fryer is placed between the heating tube and a base, a food product is placed in the fryer, and the heating tube emits heat to fry the food product in the fryer, thereby achieving a fryer function; and since the heating assembly is rotatably connected to a rotating assembly and a supporting rod is fixedly connected to the rotating assembly, when the heating assembly rotates the heating tube to face upwards by means of the rotating assembly, a pot such as a frying pan is placed on the heating tube, a food product is placed in the frying pan.

Various embodiments provide a method of frying. A method includes heating frying oil to a frying temperature and maintaining the frying oil at the frying temperature for a frying period. During the method no part of the oil exceeds 220 C. A system for using the method of frying includes a pot for holding a frying oil, a heating element for heating the frying oil, and a jacket surrounding the heating element. The jacket prevents direct contact between the frying oil and the heating element. The jacket is configured to uniformly distribute heat produced by the heating element within the pot such that the frying oil has less than 10 area % polymers at the end of heating and maintaining the frying oil at a frying temperature for a frying period.
