Description

The proposed utility model relates generally to kitchen appliances intended for the heat treatment of various food products and also called multicookers.

A device for cooking food products containing a cooking vessel for placing in it a cooking bath having a pouring device designed to move the contents of the cooking vessel. In this case, the pouring device is configured to move the contents of the brewing vessel into the pouring tank, which is removable relative to the housing. In addition, the pouring device comprises a thermostatic valve containing a heat-sensitive mechanical member having such mobility depending on the temperature that it prevents pouring out until the temperature of the cooking bath reaches a certain threshold value, and ensures pouring out when the temperature of the cooking bath reaches the turning threshold.

Such a technical solution can be used for industrial or professional devices, but it is too expensive for household appliances.

Closest to the proposed device for cooking food (multicooker) Patent US 5552577 A, SU YOUNG-SEN, 09/03/1996, A47J 27/04. This device contains a cooking container (pan) with a lid, a heating element, a base with a microprocessor and a control panel, electrically connected to the heating element and sensors for temperature and humidity (liquid) in the cooking container.

The disadvantage of this device is that its design involves a cooking technology in which the initial products are poured with cold water, followed by heating to a boil and cooked, which does not allow you to maintain the beneficial properties of the products, including trace elements and vitamins, to the maximum extent possible.

In general, heat treatment of food products is necessary to denature proteins and soften the structure of the product. The destruction of vitamins occurs, first of all, not due to heating of the product, as is usually believed, but as a result of contact with oxygen during cooking. Oxygen dissolved in water allows you to successfully destroy and oxidize vitamins and minerals.

The oxygen content in water as a function of temperature.

The technical task of the proposed utility model is to ensure maximum preservation of the beneficial properties of the starting products, mainly vitamins and trace elements. The technology of cooking products in the proposed device is based on the physical property of water "free from oxygen" as a result of boiling. The device allows from the very beginning to prepare products in water deprived of oxygen, thereby preserving to the fullest extent possible all their useful qualities. A feature of the proposed device lies in the possibility of time-programmed cooking of the starting products in an oxygen-free environment. The effect of an oxygen-free medium is supplemented by the effect of a pulsating cooking mode, that is, alternately heating / cooling the workpiece in a certain temperature range, for example, 94-97 degrees C, the so-called “languishing” effect, which in turn allows you to achieve energy savings of 30-40% . Thus, the problem of increasing the efficiency of the device is solved.

These technical problems are solved using a device for cooking food products containing a cooking container, a heating element, a base with a microprocessor and a control panel electrically connected to the heating element and temperature and humidity sensors in the cooking container and a water tank with a heating element is installed on it a lid, and a drain device including a drain pipe and an electrovalve, and the control panel and microprocessor are additionally electrically connected to the heating element mkosti a water solenoid and the sensors.

Preferably, the cooking container and the water tank are removable with respect to the base. Such a constructive solution allows to facilitate the process of filling and emptying the cooking vessel and its care - washing, drying.

The proposed device will be better understood from the description below, which is not a restrictive example of its implementation, where references are given to the drawings in the appendix, on which:

Figure 1 - schematic view of the device in assembled form;

Figure 2 is a detail view of the device shown in figure 1;

Figure 3 - functional diagram of the control device shown in figure 1;

The device for cooking food, schematically shown in figure 1 is a slow cooker containing a base 1 with a heating element 2 and a control panel 3 with a microprocessor (the microprocessor may be located behind the control panel 3 and is not shown in the drawing). A cooking container (pan) is installed above the heating element 2. The cooking container 4 is equipped with temperature and humidity sensors (not shown). A container for heating water 6 with a heating element 7 and a drain device 5, closed in the upper part by a lid 8, is installed above the cooking tank. The water tank 6 is also equipped with sensors (not shown). The solenoid valve of the drain device 5 and the heating element 7 are electrically connected to the processor 3 of the base 1.

As shown in FIG. 3, the control panel 3 is electrically connected to a microprocessor 9, which is electrically connected to the heating elements 2 and 7, with an electrovalve 5 and with sensors 10.

The electrical connections of the parts of the device can be made, for example, by means of an electric wire 11; by means of a demountable contact 12 or otherwise.

The proposed device in the example presented here, its implementation operates as follows:

In the tank 4 laid the procurement of products.

The container 6 is filled with the amount of raw water indicated in the recipe. On the control panel 3, a dish is selected (cooking mode) and the desired time is set by which this dish should be ready. The microprocessor controls the cooking mode according to the programs laid down in it.

At a certain time, the microprocessor turns on the heater 7. At the time of boiling in the water tank 6, following the command of the microprocessor, the following occurs:

- heater 7 turns off; - heater 2 turns on;

- the solenoid valve of the drain device 5 is activated and boiling water fills the cooking tank 4 by gravity.

Next, the dish is prepared in a pulsating mode, in the range, for example, 98 ° C-95 ° C (conditionally), or in any other desired mode. The microprocessor turns off the heater 2 and gives a signal about the readiness of the dish.

Water temperature of 100 degrees (boiling water) is a special case. In general, the drain device can operate at any other temperature specified by the recipe and program.

An example of cooking: stewed beef with vegetables.

Ingredients: beef 1 kg; onions 3 large; 1 large carrot; frozen eggplant, champignon mushrooms, tomatoes, sweet peppers, seasonings, spices. Cut the meat into pieces 2 cm thick, chop the vegetables coarsely, put everything in a cooking container. Pour 1 liter of raw water into the upper tank. On the control panel, turn on the “quenching” mode for 2 hours, set the ready time. For example, when laying the workpiece in the morning, the dish can be ready by 18 o’clock in the evening. The processor will execute the necessary commands to control the device according to the specified time.

The proposed utility model is in no way limited to the example of its implementation described above, but covers any modifications that do not go beyond the essence of the formula of the proposed utility model.
