The invention will be further described in detail below by means of embodiments with reference to the accompanying drawings.

Referring to Figures 1 through 9, in one embodiment, an appliance for co-cooking food with hot water and steam includes a body 1 and a food container 7 separable from the body. The body comprises a fuselage 2 and a base 3, wherein the fuselage 2 houses a water tank 4 and a boiler 5, the boiler 5 is located below the water tank 4, and the base 3 is connected to the fuselage 2, and the base 3 is from the body 1 The bottom end extends laterally and the food container 7 can be supported on the base 3. A fluid unidirectional communication is provided between the water tank and the boiler and between the boiler and the food container.

As shown in FIGS. 1 to 9, the boiler includes a boiler vessel 51, a boiler duct, and a heater 53, the water tank 4 is in communication with an inlet of the boiler vessel 51, and an outlet of the boiler vessel 51 passes through the boiler pipeline. Connected to the food container 7. In operation, the heater 53 respectively heats the boiler pipe and the boiler container 51, and when the water level in the boiler container 51 is higher than the outlet of the first boiler container, the high temperature generated in the boiler pipe Steam pressure can be used to pipe The hot water mixed with steam is fed into the food container, and when the water level in the first boiler container is lower than the outlet of the first boiler container, steam generated in the first boiler container may be Discharge into the food container.

In some embodiments, the boiler may also have two or more boiler vessels and corresponding boiler conduits to allow independent delivery of hot water and/or steam to the food container. For example, steam generated by at least one of the boiler tubes delivers hot water to the food container, and steam generated by at least one of the other boiler containers is discharged into the food container simultaneously or at the same time as the hot water.

For a particular boiler vessel in a boiler, the water level can be adjusted based on the outlet location of the boiler vessel to control the proportion of steam and hot water delivered outward. For example, if only steam is required, this can be achieved by keeping the water in the boiler vessel from reaching its exit position. It is also possible to control the power supply to the heater through a temperature monitoring device to control the heating temperature of the boiler. In this way, high temperature steam with controlled temperature and flow can be used to continuously warm the liquid or food in the food container until the food requirements are met. The ratio of steam to hot water can also be supplied by matching different boiler vessels and corresponding piping.

The water of the other pipe, the electric heating pipe 531 is thermally coupled with the boiler vessel 51, preferably by delaying heating of the boiler vessel by delaying the heating component, for example, the electric heating pipe 531 is in contact with the bottom 511 of the boiler vessel through a heat insulating plate. . Use delayed heating The components enable the energy of the heater 53 to first concentrate on heating the boiler tubes to quickly provide hot water to the food container.

Referring to Figures 4, 6, and 8, in a preferred embodiment, the outlet port of the boiler vessel 51 is configured as a height adjustable outlet, and more preferably, the outlet of the boiler vessel 51 is provided with an extension into the first An elbow tube 52 in the boiler container, the outer surface of the fuselage is provided with a first regulating terminal, such as a first knob 63, and the first knob is arranged in linkage with the elbow tube to adjust the rotation by The height and orientation of the nozzle 521 of the elbow tube within the boiler vessel adjusts the ratio of hot water to steam output in the boiler vessel 51.

For example, the nozzle of the elbow pipe 52 can be adjusted to a higher position when in use, so that the water level in the boiler vessel 51 is lower than the outlet pipe of the boiler vessel 51, at which time only the boiler vessel 51 is produced. The high temperature steam (without hot water generation) is discharged into the food container 7, in which case the appliance is a steamer or a high temperature steam sterilizer.

Referring to FIG. 4 and FIG. 8, in a preferred embodiment, the boiler pipe 61 is provided with a stop valve, and the stop valve is opened or closed together with the power switch of the heater, and the outside of the fuselage A second regulating terminal for controlling the check valve, such as the second knob 62, may also be provided on the surface, which may also be a switch, a button or the like.

The connection of the line-linking check valve to the line inlet connection is preferably screwed-in by a threaded engagement. The pressure check valve is used to prevent leakage of liquid within the food container. The line outlet preferably includes at least one separate dispensing line to break the bubble when steam and/or hot water is supplied to the food container Noise.

In other embodiments, the food container may also have steam and hot water inlets disposed on its side walls, and the base tubing may also extend to the tubing connector on the side walls of the food container.

Furthermore, the surface of the fuselage and/or food container may be marked with a water level scale, which may be used to calibrate the water level in the food container, at which time the food container is at least at a location corresponding to the water level scale It is transparent. The water level scale can also be used to calibrate the water level in the water tank, at which time the water tank is transparent at least at the location corresponding to the water level scale. By setting the water level scale and forming a transparent part of the food container and the water tank, the amount of water can be accurately observed. Since the food container is detachable, it can be used as a measuring cup to hold the required amount of water and then pour it into the water tank.

Referring to Figures 1 and 14, the food container may be cup-shaped, or may be a steamer type and agitating type as shown in Figs. 15 and 16, or may be a crucible or the like suitable for heating food with hot water and steam. Container form.

Referring to Figures 16-18, a food container having a stirring and/or pulverizing function may be provided, unlike a cup-shaped food container. In the latter embodiment, the body includes an electric drive unit, and the food container is disposed at the bottom. There is a stirring device 80 comprising a drive motor 81 disposed within the fuselage and a drive assembly within the base, the drive motor being capable of driving the agitation device through the drive assembly. The transmission components are, for example, gear sets 82, 84 and a drive belt 83 that cooperates therewith. A cooling fan 85 can be disposed around the drive motor 81.

The stirring device may be a stirring knife or a stirring rod for pulverizing or stirring the food. The agitation means is preferably detachably mounted to the bottom of the food container. In some preferred embodiments, the agitating means is movably coupled (ie, detachable) to a transmission assembly within the base, and is coupled to the base when the food container is locked with the base In one piece, it can also be separated from the base together with the food container.

Referring to Figures 16-20, for a food container with a stirring device, the axis of the agitating device is typically centered at the bottom of the food container, so in this embodiment, the tubing on the base is linked to the check valve 31 and the bottom of the food container. The tubing connector is placed at a position offset from the center of the bottom of the food container. Since the food container is preferably screwed into the base, a curved elongated hole 86 centered on the center of the bottom is provided at the pipe joint of the base on the base to enable the food container to be rotated relative to the base to the locked position or Unscrew from the locked position.
