Abstract
The invention relates to a range hood capable of preventing power failure. On the basis of a common range hood, a frequency converter, a storage battery and a charger are arranged beside a junction box and an air outlet on the upper part of a box body. When the power supply condition is normal at ordinary times, a power cord supplies power to a motor of the range hood and charges the charger, and the charger charges the storage battery; when the storage battery is saturated, the charger stops charging the storage battery and automatically shuts down the power supply per se; when a power grid stops supplying power due to line failure or overload, a special control switch is pressed down, the storage battery with saturated charge makes the frequency converter connected therewith work, and the frequency converter converts low-voltage DC into 220V AC to supply power to the motor of the range hood so as to make the range hood continuously work and discharge the oily fume generated by cooking continuously; therefore, the cleanness of air in a kitchen is maintained under the condition of power failure.
Description
One, technical field
The present invention relates to a kind of range hood of having a power failure of preventing.
Two, background technology
At present, range hood industry both domestic and external is the same with other each fields, and the competition on fighting for client, expanding market is more and more fierce.Especially under the situation of the international financial crisis of have swepting the globe in this year, each manufacturer must constantly innovate the product of oneself for will try to achieve existence, continuous the performance of each side is improved and perfect.The a recent period of time, I notice, when city zoning maintenance power network line or because of network load when too heavy, the phenomenon that short-term has a power failure can take place, this makes the range hood that uses in the kitchen lose effect, oil smoke is in time effluxed, can not keep the air cleaning in the kitchen, thereby people's health has been brought harm to a certain degree.
Three, summary of the invention
The present invention is directed to the defective of above-mentioned existence, the technical scheme of technical problem to be solved and proposition is:
Invent a kind of range hood of having a power failure of preventing, even the power failure phenomenon takes place and still can guarantee normal work in the short time during operation for it, thereby the air cleaning in the maintenance kitchen a kind of prevents the range hood that has a power failure, its technical scheme is: it comprises the lubricating cup of bottom collection sump oil, oil-collecting net on the lubricating cup, the inner bag that oil-collecting is online, cover the upper cover plate and the front shroud that switch is housed and the built-in motor that cover inner bag the place ahead of inner bag top, wind wheel, the air channel, air outlet is placed at the top, the outside is with the casing of parts such as cover of upholstery, it is characterized in that above casing a frequency converter has been installed on the next door of terminal box and air outlet, battery and charger; One special control switch is set on front shroud.Charger one end links to each other with the power line of range hood, and the other end and battery join; One end of frequency converter links to each other with battery, and the motor in the other end and charger, special control switch and the range hood casing joins.Work as electric power thus supplied just often at ordinary times, power line is given the motor power supply of range hood on the one hand, make it operate as normal, (charger is built-in with rectifier to charger in power supply on the other hand, making AC rectification is direct current), charger charges to battery again, after battery is saturated, charger promptly stop to the charging of battery and voluntarily powered-down to the power supply of charger.When power network line hinders or the excessive range hood of stopping power supply of loading can not work the time for some reason, press special control switch, the battery that electric charge is saturated just makes the frequency converter work that is attached thereto, frequency converter just is converted into the alternating current of 220V to the direct current of low pressure and by the terminal box (electrical apparatus control system) of range hood the motor of range hood is implemented power supply, range hood is worked on, what the oil smoke that allows culinary art produce kept effluxes, thereby has kept the cleaning of air in the kitchen under situation about having a power failure.
Four, description of drawings
Fig. 1 prevents the range hood structural representation that has a power failure for the present invention is a kind of.
Among the figure: 1, lubricating cup; 2, oil-collecting net; 3, inner bag; 4, casing; 5, battery; 6, charger; 7, frequency converter; 8, terminal box (electrical apparatus control system); 9, air outlet; 10, upper cover plate; 11, front shroud; 12, special control switch.
Fig. 1 illustrates: a kind of range hood that prevents to have a power failure of the present invention is on the basis of original range hood, and above casing 4, a frequency converter 7 has been installed on the next door of terminal box 8 and air outlet 9, battery 5 and charger 6; Charger 6 one ends link to each other with the power line of range hood, and the other end and battery 5 join; One end of frequency converter 7 links to each other with battery 5, and the other end joins by the motor in terminal box 8 and special control switch 12 and the range hood casing.
Five, the specific embodiment
Below in conjunction with accompanying drawing a kind of implementation process of the range hood that has a power failure of preventing of the present invention is described further:
(1), manufacture process:
The present invention is a kind of to be prevented the manufacturing of the range hood that has a power failure the range hood with conventional in the past is identical generally, and institute's difference is above casing 4, and the next door of terminal box 8 and air outlet 9 installs a frequency converter 7 additional, battery 5 and charger 6; One end of charger 6 links to each other with the power line of range hood, and the other end and battery 5 join; One end of frequency converter 7 links to each other with battery 5, and the other end joins through the motor in terminal box 8, special control switch 12 and the range hood casing, has so just finished the manufacturing of this machine.
(2), use:
When electric power thus supplied just often, power line is given the motor power supply of range hood on the one hand, make it operate as normal, (charger is built-in with rectifier to charger 6 in power supply on the other hand, making alternating current is direct current), charger 6 charges to battery 5 again, after battery 5 is saturated, charger 6 promptly stop to the charging of battery 5 and voluntarily powered-down to the power supply of charger 6.When power network line hinders or the excessive power supply of loading when stopping for some reason, as long as press the special control switch 12 on the front panel 11, the battery 5 that electric charge is saturated just makes frequency converter 7 work that are attached thereto, the motor of the terminal box 8 pair range hoods of the alternating current that frequency converter 7 just is converted into 220V to the direct current of low pressure by being provided with electrical apparatus control system is implemented power supply, range hood is worked on, what the oil smoke that allows culinary art produce kept effluxes, thereby has kept the cleaning of air in the kitchen under situation about having a power failure.
