Problems solved by technology

[0005] Depend on Figure 18 and Figure 19 It can be seen that the existing air curtain devices only form an upward airflow, and the attenuation of the airflow in the axial direction is relatively serious, and the shielding effect in practical applications is not ideal, so further improvement is needed

Embodiment 1

[0042] See Figure 1 ~ Figure 5 , A stove with an air curtain generating device, the stove being an electric stove, including a stove body 1, a stove top 2 and an air curtain generating device 3. The stove body 1 is in the shape of a hollow box with an opening on the top surface, and the stove 2 is set on the stove On the top surface of the body 1, the air curtain generating device 3 is arranged in the stove body 1. The stove top 2 is provided with a stove core 21 and a control switch 22 for controlling the stove core 21. In this embodiment, the stove core 21 is two electrically heated stove cores arranged at intervals.

[0043] The air curtain generating device 3 includes a fan 31, an air duct 32 and an air outlet device 33, and each stove core 21 corresponds to an air curtain generating device 3. The air outlet device 33 includes a cylindrical first housing 331 and a second housing 332, the first housing 331 and the second housing 332 are arranged concentrically, and the diamet...

Embodiment 2

[0048] See Figure 7 with Figure 8 In this embodiment, the difference from the first embodiment is that the stove is a gas stove, and the outer periphery of the stove core 21 is provided with a bracket 211 for supporting the pot. Due to unsafe factors such as the flame being blown away or drained by the gas stove, a flame shield ring 24 is provided on the radially inner side of the vent 23 on the stovetop 2 and the radially outer side of the stove core 21 to avoid flame shielding. The ring 24 completely shields the air flow emitted from the vent 23 without forming a vortex wind curtain, and can ensure a certain shielding effect. Preferably, the height of the flame shield ring 24 is recorded as h, 30cm≤h≤60cm, and the diameter is d, And d≥250cm (adjustable according to the size of the stove core 21).

Embodiment 3

[0050] See Figure 9~Figure 11 In this embodiment, the difference from the first embodiment above is that the stove is an integrated stove, and the stove adopts a gas stove. Because the gas stove has unsafe factors such as the flame being blown away or drained by the airflow, the stove on the stovetop 2' The core 21' adopts a deep well type, and a bracket 211 is provided at the bottom for supporting the pot. In addition to the stove body 1'and the stove 2'set on the stove body 1', it also includes a bottom row type oil fume suction system. The suction port can be on the top or next to the stove core 21', inside the stove body 1' Other kitchen appliances can also be set up, such as appliances with functions such as disinfection, drying, and storage.

[0051] The air curtain generating device 3 is arranged in the stove body 1'and surrounds the stove core 21', and the vent 23' is located around the top of the stove core 21'. A fixing plate 11 is arranged in the stove body 1', and t...

Abstract

The invention discloses a cooking utensil with air curtain generating devices. The cooking utensil with the air curtain generating devices comprises cooking benches and the air curtain generating devices, wherein the cooking benches are provided with cooking cores; the air curtain generating devices comprise fans, and air exhausting devices which are used for blowing out airflows generated by the fans; the air exhausting devices are located on the peripheries of the cooking cores; and moreover, multiple air outlets are formed in the air exhausting devices. The cooking utensil with the air curtain generating devices is characterized in that the air outlets are oblique relative to both the horizontal direction and the vertical direction; and the airflows are enabled to have horizontal tangential velocity components, relative to the centers of the cooking cores, when passing through the air outlets. Through providing shearing force in the horizontal direction, the rotary motion is transferred through the self viscous shearing force or the turbulent shearing force of a fluid; oil fume is enabled to form a vortex; the effect of shielding ambient airflows can be achieved to some extent; a smoke sucking area of an extractor hood is controlled; meanwhile, the cyclone aspiration is formed; and the smoke gathering and sucking capacity is promoted.

Description

Technical field [0001] The invention relates to a kitchen appliance, in particular to a stove with an air curtain generating device. Background technique [0002] At present, the commonly used gas stoves, electric stoves and other stoves, the oil fume and exhaust gas generated during the cooking process are exhausted by the range hood installed above the stove. Since the rise of oil fume is mainly affected by temperature gradient and pressure gradient, for the range hood, its effective smoke control range is limited, and the actual control ability of the oil fume path is weak. While inhaling oil fume, a large amount of fresh air is also inhaled, and the actual suction efficiency of the range hood is not high. [0003] In order to solve the above problems, there has also been a scheme of adding an air curtain type smoke guide to the existing stove. According to the aerodynamic principle that the air curtain can block the air convection, an air curtain is formed around the stove to ...
