(Embodiment 1)
As shown in FIGS. 1 and 2, the main body 1, the fan 2 that sucks in air containing smoke and heat generated during cooking, and the water used in the water storage case 3 are used and contained in the sucked air. A hydrophilic filter 4 that removes contaminated components, a deodorizing filter 5 that removes odorous components (not immersed in water), and a vaporization heat filter 6 that removes the heat of air that passes through the water stored in the water storage case 3. And a wind direction control means 7 capable of controlling the wind direction when the air after passing through the hydrophilic filter 4, the deodorizing filter 5 and the vaporization heat filter 6 is circulated in the kitchen, the hydrophilic filter 4 and the deodorizing filter 5. The water after passing through the vaporization heat filter 6 is circulated in the kitchen or the outside is supplied with water to the damper 8 and the water storage case 3 for supplying water to the water storage case 3 and the damper 8 for selecting the exhaust to the outside. And drain And Meniben (room) 10 and the valve (outdoor) 11, a configuration provided with a temperature detecting means 12 for measuring the temperature in the kitchen.

  In the above-described configuration, the operation until the air containing smoke and heat generated during cooking is reused and circulated or exhausted into the room will be described with reference to FIGS.

  First, the flowchart of FIG. 4 will be described for each operation step.

  Before operating the range hood, water is supplied from the water storage tank 9 to the water storage case 3, and at the same time as the supply, the time is started to be accumulated by the accumulating means 13 to make it operable. Here, the integrating means 13 is preferably an EEPROM that is used by being electrically connected to a microcomputer (STEP 1 to STEP 2).

  Start the operation of the range hood after water supply. The air containing smoke and heat generated when the user cooks is sucked with the fan 2 and passes through the hydrophilic filter 4 and the deodorizing filter 5 to remove dirt components and odor components contained in the sucked air. Further, the thermal component can be removed by passing through the vaporization heat filter 6. Further, when the time t1 accumulated by the accumulation means 13 becomes larger than the preset time T1, the valve (indoor) 10 and the valve (outdoor) 11 are opened to drain the water in the water storage case 3, After draining, the valve (indoor) 10 is opened and the valve (outdoor) 11 is closed to supply water from the water storage tank 9 to the water storage case 3. When t1 is smaller than T1, the water in the water storage case 3 is not replaced. Here, T1 is preferably about 24 to 72 hours in order to stably supply clean water to the hydrophilic filter 4 and the vaporization heat filter 6. The valve (indoor) 10 and the valve (outdoor) 11 are electrically connected to a microcomputer (STEP3 to STEP6).

  After the sucked air passes through each filter, when the temperature t2 in the kitchen detected by the temperature detection means 12 is higher than the preset temperature T2, the wind direction control means 7 is opened and the damper 8 is closed. The air that has passed through the filter is circulated in the kitchen. When t2 is lower than T2, the air direction control means 7 is closed and the damper 8 is opened, so that the air that has passed through the filter is exhausted outside without being circulated in the room. Further, it is assumed that the circulation or exhaust can be freely selected by controlling the wind direction control means 7 and the damper 8 forcibly according to the user's request without depending on the value of the temperature detection means 12. Here, the temperature detection means 12 is preferably a thermistor, the wind direction control means 7 is a movable louver, and T2 is preferably in the temperature range of about 25 ° C. to 40 ° C. Further, it is assumed that the wind direction control means 7 and the damper 8 are electrically connected to the microcomputer (STEP 7 to STEP 10).

  When the use of the range hood is stopped, when the wind direction control means 7 is opened and used, the wind direction control means 7 is automatically closed simultaneously with the stop (STEP 11 to STEP 12).

  The range hood of the present invention enables the air from which dirt, smell, and heat components generated during cooking are removed to be circulated in the kitchen. Useful.
