Solar negative pressure range hood

Abstract

An existing range hood has the problems that a motor and an impeller are polluted by lampblack and the like. Although various and oil-free methods are designed in the world, the real problem of unpicking and washing cannot be solved. The solar negative pressure range hood is invented according to the principles of fluid mechanics and aerodynamics. An energy storage type solar photovoltaic panel is used for supplying power, air blown out by a fan sprays high-speed airflow at a nozzle of a pipeline, air around the airflow is slow in speed, large in pressure and slow in speed, the airflow at the nozzle is high in speed and small in pressure, vacuum negative pressure is formed, and in order to maintain balance, the airflow in an air suction pipe flows towards the nozzle and sucks oil smoke. And the air flow enters the vacuum cavity and is sprayed out of the nozzle. And the oil smoke is mixed in the pipeline and discharged outdoors through the oil smoke purifier. The lampblack does not pass through the motor, the impeller and the like, so that the real trouble of disassembly-free and washing-free is solved.

Description

Technical Field

[0001] The invention patent relates to a "solar negative pressure range hood". Background Art

[0002] The current range hoods have problems such as oil fume contaminating the motor and impeller. Although various methods of non-stick oil have been designed in the world, they still cannot solve the real problem of no disassembly and cleaning. Summary of the invention

[0003] The "solar negative pressure range hood" was invented based on the principles of fluid mechanics and aerodynamics. It uses energy storage solar photovoltaic panels to power the air. The wind blown by the fan sprays out high-speed airflow at the nozzle of the pipe. The air around the airflow has a slow flow rate and high pressure. The air flow rate is slow, and the airflow at the nozzle has a fast speed and low pressure, forming a vacuum negative pressure. In order to maintain balance, the airflow in the suction pipe flows to the nozzle, sucking in the oil fume. The airflow entering the vacuum chamber and the airflow sprayed from the nozzle are mixed in the pipeline and discharged outdoors through the oil fume purifier. Since the oil fume does not pass through the motor and impeller, etc., it solves the real trouble of no disassembly and cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0005] Description of the drawings: a. The energy storage type solar photovoltaic panel (7) is powered by electricity. Under the linkage of the duct booster fan (1), the wind blown out by the main fan (3) is mixed with the main air inlet (18) in the three-way (5) pipe through the nozzle (4), and enters the energy storage chamber (9) through the elbow (10) and the linkage of the 110,000 rpm high-speed fan (11). It is discharged to the outside through the smoke purifier (8) and the smoke hose outlet (6). b. The oil smoke air in the kitchen is discharged to the outside for the second time through the secondary air inlet air purification net (2), and the kitchen is clean and tidy. c. According to the principle of aerodynamics, a strong dominant wind must be present to form a strong vacuum suction force. In order to solve this problem, the linkage between the energy storage chamber (9) and the 110,000 rpm high-speed fan (11) should be established to ensure the efficiency of wind direction turning. This is the key technology for the application of the range hood. d. The construction of an energy storage type solar photovoltaic power station is green, environmentally friendly, and energy-saving. e. Xiao Du Xiao Du, voice intelligence (14) realizes intelligent automatic control of some programs such as switches, lighting, fire protection interface (16), electric fan (13), cooking methods and menus, seasoning library (12), etc.

[0006] The prototype trial has been successfully produced.

Claims

1. The solar negative pressure range hood is powered by an energy storage type solar photovoltaic panel (7) in turn. When the duct booster fan (1) is in motion, the wind blown out by the main fan (3) is mixed with the main air inlet (18) in the three-way pipe (5) through the nozzle (4), and enters the energy storage chamber (9) through the elbow (10) and is in motion with the 110,000 rpm high-speed fan (11). The wind is then discharged to the outside through the smoke purifier (8) and the smoke exhaust hose outlet (6).

2. According to claim 1: the wind blown by the fan sprays out high-speed airflow at the nozzle of the pipe. The air velocity around the airflow is slow and the pressure is high. The air velocity is slow, and the air velocity at the nozzle is fast and the pressure is low, forming a vacuum negative pressure, thereby causing the airflow in the suction pipe to flow to the nozzle, sucking in the oil fume. The airflow entering the vacuum chamber and the airflow sprayed from the nozzle are mixed in the pipe and discharged outdoors through the oil fume purifier.

3. Establish linkage between the energy storage room (9) and the 110,000 rpm high-speed fan (11) to ensure the efficiency of wind direction turning.
