Description

Integrated kitchen

Technical Field

The utility model relates to the field of stoves, in particular to an integrated stove.

Background

The integrated kitchen range is a combined kitchen appliance, which combines a kitchen range, a range hood, a cooking device and the like. Such as chinese utility model patent No. zl202122910382.X (issued patent No. CN 216557216U), chinese utility model patent No. zl202122811984.X (issued patent No. CN 216557213U), chinese utility model patent No. ZLCN216557213U (issued patent No. CN 216521867U), etc. The range hood is generally arranged at the rear side of the kitchen range and the cooking device and is used for sucking the oil smoke generated in the cooking process.

The cooking device for the integrated kitchen is generally provided with a hot air baffle plate at the rear side of the inner cavity of the inner container, the hot air baffle plate and the back plate of the inner container enclose a hot air chamber, an impeller of the hot air blower is positioned in the hot air chamber, and a back heating pipe is arranged at the periphery of the impeller. When the cooking equipment works, the air heater rotates to form negative pressure at the air inlet of the hot air baffle, gas in the inner container is sucked into the hot air chamber under the action of the negative pressure, and the gas entering the hot air chamber is heated into hot air and then flows back into the inner container through the air outlet of the hot air baffle under the action of the centrifugal force of the impeller, so that the hot air circulation inside the inner container is realized. In addition, the inner container of the cooking device has a trend of developing in a large volume direction (most of the current inner containers are more than 60L), and the power of the air heater is smaller, so that the large air volume baking cannot be realized due to the lower rotating speed of the air heater when the cooking device works in a baking mode, the hot air circulation is slower, and the baking effect is poor.

In order to solve the above problems, two air heaters are arranged up and down in the inner container of the conventional cooking device, such as chinese patent No. ZL 202122401928.9 (issued notice No. CN 216293804U). However, the arrangement of the upper and lower twin air heaters in the integrated cooker causes the following problems:

(1) The height of the inner container is increased, so that the height of the cooking device is increased, and devices, such as a disinfection cabinet and the like, which are not beneficial to integrating other functions of the kitchen in the height direction are integrated;

(2) The upper and lower hot air blowers can lead to the disorder of the wind field in the inner container and the uneven temperature field in the inner container;

(3) The upper and lower air heaters are respectively provided with the driving motors, so that a plurality of motors work simultaneously when the integrated kitchen is in work, and the working noise is high.

Further, the diameter of each hot air impeller is 40% -60% of the height of the inner container. The large-size hot air impeller is beneficial to realizing large air quantity of the hot air impeller.

Further, each heating pipe is in a circular ring shape, and the radius of each heating pipe is respectively matched with the corresponding hot air impeller. So that each heating pipe can fully heat the air entering the hot air chamber.

Therefore, the clutch for controlling the contact and separation of the shaft hole edge of the first transmission gear and the rotating shaft is also arranged in the mounting interlayer.

Further, the clutch is fixed on the back surface of the inner container and is adjacently arranged on the front side of the first transmission gear,
