## Background
BACKGROUND OF INVENTION
1. Field of the Invention
The present invention relates to a vertical type air humidifying and air purifying machine, more particularly to a dual purpose air humidifying and air purifying machine.
2. Brief Description of Prior Art
Accompanying with the progress of civilization, natural environment has been becoming more and more deteriorated. Especially, the air pollution caused by industrial poisonous gas and gas exhausted from cars and motorcycles are among the serious pollutant sources. In the meantime, people are increasingly paying more attention to the environmental protection issues. Hence, various air purifying apparatuses have been created in response to this situation. Furthermore, as water is easily evaporated in dry air environment, people often get dry or cracking skins which make people feeling discomfortable. Therefore, it becomes very important to artificially increase the humidity in the indoor air so that the environment will not become too dry.
In view of the abovementioned situation, various humidifiers for adding humidity to indoor air and various air purifiers for purifying indoor air are present on the market, such as Taiwanese Patent No. M397500 “Air purifying and humidifying machine”, Taiwanese Patent No. M380458 “Cooling and Heating type humidifier”, Taiwanese Patent No. M327457 “Heating and Humidifying Machine”, Taiwanese Patent No. I264514 “Safe Structure of Humidifier”, Taiwanese Patent No. M419889 “Separate Type Air Purifier”, Taiwanese Patent No. M416057 “Cooling and Heating Type Air Purifier”, Taiwanese Patent No. M404950 “Air Purifier having Air Quality Displayed”. However, each of these patents only has a single function of either air humidifying or air purifying, and thus they fail to satisfy the appeal of consumers.
SUMMARY OF THE INVENTION
In order to satisfy the demand of customers, the inventor of the present invention proposes a dual purpose machine enabling air humidifying and air purifying, and the machine can be operated according to the local environment demand of customers.
A vertical type air humidifying and purifying machine, comprising a front casing, a rear casing, a humidifying unit, an ultraviolet light purifying unit, a motor-fan unit and a negative ion generator; in which the front casing and the rear casing are assembled correspondingly with each other, and the humidifying unit, the UV light purifying unit, and the motor-fan unit are disposed orderly in upper-down direction between the front and the rear casings, and the negative ion generator is installed at an air outlet of the motor-fan unit: switches being respectively provided on the humidifying unit, the UV purifying unit and the negative ion generator for ON-OFF switching.
Configuring like this, users can start one or over two of the humidifying unit, the UV purifying unit and the negative ion generator provided on unitary machine independently so as to conduct air humidifying or air purifying independently, or to conduct air humidifying and air purifying simultaneously. Accordingly, the implementation of its overall structure can be conformed more closely to the reality situation.
That is, the vertical type air humidifying and purifying machine is a dual purpose machine enabling air humidifying and purifying, in which water mist is discharged by the humidifying unit to the top end of the machine for ejection and the air purified can be discharged by the motor-fan unit to the top end; both the humidifying unit and the motor-fan unit can work independently or simultaneously. Therefore, the overall implementation conforms more closely to the reality situation; hence better selective operation can be achieved so that the defect of conventional machine with single function can be improved.
