Abstract

The invention relates to a temperature control and frequency conversion range hood, in particular to a range hood with a thermal induction automatic switch or a frequency conversion type range hood, which aims to solve the problems of more power consumption and incomplete pumping of a pumping unit, adopts temperature control to start up in time and adopts a large, medium and small fire three-stage sensing control frequency conversion electric exhaust fan to achieve the purposes of saving power consumption and completely pumping oil smoke, is very suitable for being selected and applied by household users in the aspect, and is more suitable for being produced, sold and popularized by professional manufacturers.

Description

Thermal induction automatic switch's smoke ventilator or inverter type smoke ventilator

The technical field is as follows: the invention relates to a heat-induction automatic-switching range hood or a variable-frequency range hood, belonging to the field of range hoods.

The second aspect is that the problem that the oil smoke cannot be timely pumped out to cause full room oil fragrance and the problem of power waste when a user forgets to turn on or off the oil smoke ventilator is solved, and the? invention is a technical scheme for solving the two problems.

The invention content is as follows: in order to solve the two problems of the range hood, the temperature control induction can be adopted to control the on and off of the power switch of the range hood, so that the aim of intelligently switching the range hood without manual operation is fulfilled, and the second problem is solved. The variable-frequency exhaust fan with larger power is half to two times larger than the common exhaust capacity and can prevent oil smoke pollution, so that a large amount of generated oil smoke can be exhausted completely in time when dishes are fried, and the problem of the second aspect is solved.

The specific implementation scheme is as follows: in order to realize the invention, the specific implementation scheme is characterized in that: the first scheme is that temperature controllers are installed on the top surfaces of various range hoods, induction probes of the temperature controllers are installed below air inlets of the range hoods, namely the side edges of the range hoods close to a gas stove, and are used for sensing that the gas stove is ignited to prepare for cooking, when the gas stove senses that the temperature exceeds 45 ℃, a power switch of an exhaust fan is automatically started to enable the range hoods to start to work, the temperature controllers adopt the existing temperature controllers, and the temperature controllers are set within the range of 35-60 ℃ by using set temperature control temperature. Temperature control temperature lower than normal temperature can not be set, and high temperature control temperature can not be set, otherwise the problems of no stop for a long time and no starting of the smoke exhaust ventilator when cooking is started can be caused.

The second scheme is that the ordinary exhaust fan is changed to adorn the frequency conversion exhaust fan that can prevent that power of oil smoke pollution is half to the twice more greatly, this frequency conversion exhaust fan that can prevent oil smoke pollution adopts to prevent that oil removal cloth wrapping bag packing this motor is sealed oil pollution prevention in the bag, the power of this fan is connected the supply by the converter electricity, this converter is selected to be suitable for, adopt ready-made market product to be connected with the temperature controller electricity, this temperature controller chooses the finished product of selling for use, the probe of this temperature controller must be installed in the air intake below of smoke ventilator or the position of nearly gas furnace, the purpose lets the probe ability perception temperature in time, the perception gas furnace has igniteed promptly and has boiled water fried dish, need to extract oil smoke steam can the automatic start smoke ventilator pump drainage work promptly. The temperature control variable frequency range hood is divided into three stages of variable frequency air draft, namely a small fire stage, a medium fire stage and a large fire stage, wherein the small fire stage refers to that when the gas furnace is opened to cook and boil with small fire, oil smoke or water vapor is generated less, and when the temperature is in the range of the first-stage radiation temperature of 30-50 ℃, the power supplied to the air draft fan by the frequency converter is smaller, if a user increases the firepower of the gas furnace to be medium fire or when the gas furnace is large fire, namely the radiation temperature is 51-60-61-80, the power supplied to the air draft fan is correspondingly increased, so that the purposes of increasing the oil smoke and water vapor, namely large air draft power and large air draft power consumption, and otherwise, correspondingly reducing the power saving and reaching the standard are achieved, namely, the purposes of saving power and completely exhausting the oil smoke and the water vapor.

Claims

1. The smoke ventilator or the frequency conversion type smoke ventilator with the thermal induction automatic switch is characterized in that: the first scheme is that a temperature controller is installed on the top surface of various range hoods, an induction probe of the temperature controller is installed below an air inlet of the range hood, namely, the induction probe is installed on the side edge of a near gas stove and used for sensing that the gas stove is ignited to prepare for cooking, a power switch of an exhaust fan is automatically started to enable the range hood to start to work when sensing that the temperature exceeds 45 ℃, the temperature controller adopts the existing temperature controller, the temperature controller is set within the range of 35-60 ℃ by using a set temperature control temperature, the temperature control temperature lower than the normal temperature cannot be set, and the high temperature control temperature cannot be set, otherwise, the problem of failure that the range hood is not stopped for a long time and the range hood is.

2. The smoke ventilator or the frequency conversion type smoke ventilator with the thermal induction automatic switch is characterized in that: the second scheme is that a common exhaust fan is replaced with a variable frequency exhaust fan which can prevent oil smoke pollution and has power which is half to two times larger than that of the common exhaust fan, the variable frequency exhaust fan which can prevent oil smoke pollution is packaged in an oil-proof cloth packaging bag, the motor is sealed in the bag to prevent oil pollution, the power of the fan is electrically connected and supplied by a frequency converter, the frequency converter is suitable for selection, a ready-made commercially available product is electrically connected with a temperature controller, the temperature controller selects a commercially available finished product, a probe of the temperature controller is required to be arranged below an air inlet of the gas cooker, or at a position close to the gas cooker, the probe is used for sensing the temperature in time, namely sensing the gas cooker to be ignited and cooked with water to fry, automatically starting the gas cooker to pump and exhaust the gas cooker when oil smoke steam is required to be extracted, the temperature control variable frequency gas cooker is divided into three stages of variable frequency exhaust, namely a small fire stage, a medium fire stage and a large fire stage, and the small fire stage, when the temperature is within the range of first-stage radiation temperature of 30-50 ℃, the power supplied to the exhaust fan by the frequency converter is smaller, if a user increases the firepower of the gas furnace to be medium fire or big fire, namely, when the radiation temperature is 51-60-61-80, the power supplied to the exhaust fan is correspondingly increased by the frequency converter, so that the purposes of more oil smoke and water vapor, namely, large air draft power, more electricity for air draft and correspondingly reduced electricity saving and reaching the standard are achieved, namely, the purposes of saving electricity and completely and cleanly pumping away the oil smoke and the water vapor are achieved.
