The utility model relates to the field of thermal equipment for public catering enterprises, in particular, to steam-convection apparatus and can be used both independently and as part of a technological line.

Known steam-convection apparatus (1) containing a casing, base, insulated working chamber, door, shelf holders, fan, heating elements installed on both sides of the fan, control panel, steam generator, water supply and wastewater system.

A disadvantage of the known apparatus is the lack of cooking programs and automatic washing.

The closest in technical essence to the claimed solution is a steam-convection apparatus (2) containing a casing, base, heat-insulated working chamber, door, shelf holders, fan, heating elements installed on both sides of the fan at an equal distance from it, control panel , steam generator, water supply and sanitation system.

A disadvantage of the known apparatus is also the lack of cooking programs and automatic washing.

The technical result of the utility model is the expansion of the functionality of the device.

The technical result is achieved by the fact that in a steam-convection apparatus containing a casing and a heat-insulated working chamber installed on the base, a door, a control panel, a steam generator, a water supply and drainage system, as well as shelf holders, a fan, and heating placed in the working chamber

elements, a control unit is installed inside the steam-convection apparatus, and the control panel contains a touch screen. In addition, for the implementation of automatic washing, a pump, dispensers and shut-off taps are introduced into the device.

A distinctive feature of the utility model is that a control unit is additionally introduced into the known steam-convection apparatus, the control panel contains a touch screen, and a pump, dispensers and shut-off valves are introduced into the device for automatic washing.

Figure 1 presents a General view of a steam-convection apparatus, figure 2 - water supply and sanitation and washing system.

Steam-convection apparatus (hereinafter PKA) contains a heat-insulated working chamber 1 located in the casing 3, mounted on the base 20. Inside the working chamber 1, shelf holders 4 are installed, as well as fan 2 and heating elements (not shown in the drawing) shown) equally spaced from the fan. The holders of the shelves 4 can be made in the form of vertical racks to which the shelves are attached. The fan 2 is driven by an electric motor (not shown in the drawing) mounted on the side wall of the working chamber 1.

The circulation of air in the working chamber 1 is ensured by suction by the fan 2 of air from the working area of the chamber and forcing it back into the working area using the heat energy received from the heating elements.

The heating elements are located around the fan at an equal distance from it, which ensures uniform receipt of thermal energy from them, and, consequently, a more uniform heating of the working chamber, providing improved quality of the cooked product.

To partially seal the working chamber 1, door 5 is used. On the front surface of the casing 3, a control panel 6 with a touch screen is installed. Using the control unit 7, the selection of existing cooking programs, as well as the recording of new programs.

The water supply and wastewater system (Fig. 2) contains a solenoid valve 9 for supplying water to the steam generator 10, a tank 11 for monitoring the liquid level in the steam generator 10, a thermal switch 12

(130 ° С), a valve 13 for releasing air into the atmosphere with an electric actuator, a drainage collector 14, draining water into the sewer 15.

The washing system PKA (figure 2) contains a tee 16, the drain valve from the oven 17, the pump 18 and the dispensers 19.

The steam generator 10 generates and provides steam to the working chamber at various predetermined modes. Water in the steam generator 10 comes from the water supply network. The water level is maintained automatically by means of an electromagnetic valve 9. To control the water level in the steam generator 10, a tank 11 with electrodes installed in it (not shown) is used. When the water level in the tank 11 drops below a predetermined value, the electromagnetic valve 9 opens and the steam generator 10 is filled. When the water in the tank 11 rises to the upper level, the valve 9 closes and the water supply stops. To prevent an emergency situation when the automatic water supply system fails, a thermal switch 12 is installed in the steam generator 10, which, when the temperature in the steam generator reaches 130 ° C, turns off the PCA. For ventilation of the working chamber, a valve 13 is used to release air into the atmosphere with an electric actuator, which opens only to the convention mode. The collector 14 allows for constant communication with the atmosphere and to prevent the creation of excessive pressure in the chamber.

Steam, passing through the working chamber 1, enters the drainage collector 14, where it is cooled, and the resulting water is discharged into the sewer through drain 15.

The washing system is controlled by the control unit 7. Hot water from the steam generator 10 through the tee 16 is fed into the oven. Then, water is pumped periodically to the fan 2 using the pump 18. Dosing of detergent and rinse aid is carried out using dispensers 19. The waste solution is drained into the sewer using the drain valve from the oven 17.
