Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology and relates to an air conditioner for purifying oil fumes suitable for kitchen use, specifically a multi-functional air conditioner for purifying oil fumes. Background Technology

[0002] In kitchen fume purification, the most common and widely used method is the household kitchen range hood. These hoods are equipped with oil filters to intercept larger oil particles from entering the cavity. However, after several years of use, the centrifugal impeller and the inner walls of the cavity become covered in grease, indicating that even finer oil fumes are still being directly emitted into the outdoor environment. This continuous emission from countless households contributes to atmospheric pollution.

[0003] In a home kitchen environment, a range hood can only remove some of the fumes and heat. In the hot summer, the heat generated by the gas stove in the kitchen causes the kitchen temperature to rise significantly. Currently, there is no effective kitchen-specific air conditioner to solve the problem of cooling the kitchen. Summary of the Invention

[0004] This utility model discloses a multifunctional oil fume purification air conditioner, which consists of a fume hood, an oil filter, a smoke pipe, an oil fume purification air conditioner, and an integrated electronic control and display system. Its key feature is that the lower end of the oil fume inlet of the oil fume purification air conditioner has an oil fume removal component consisting of a water tank, a submersible pump, a water spray pipe, and nozzles. The centrifugal fan inlet of the oil fume purification air conditioner is connected to a cyclone centrifugal dehydrator. When the submersible pump installed in the water tank pressurizes water mixed with an oil-water emulsifier and sprays it onto the nozzles of the water spray pipe, it forms a water mist. The oil fume gas is washed by the water mist. Under the combined action of water and emulsifier, the oil in the oil fume gas is washed into the water. The water droplets in the clean air after washing are dehydrated and separated three times by a baffle plate, a cyclone dehydrator, and a centrifugal fan impeller. The water then flows back to the water tank, and the clean air after oil removal and dehydration is discharged through the air outlet.

[0005] The air outlet has an indoor / outdoor air switching valve, which can be used to either exhaust clean air to the outside or return it to the room.

[0006] Inside the aforementioned fume purification air conditioner, the space for spraying and washing the fume is filled with multi-faceted hollow spheres, which increases the contact area between the sprayed water mist and the fume, thereby enhancing the washing effect.

[0007] The water tank contains an electrically controlled drain valve, an overflow pipe, a water level sensor, and an electrically controlled water supply valve. During spraying, water will evaporate and be consumed. The electrically controlled water supply valve will automatically replenish the water in the water tank to meet the water volume required for spraying.

[0008] The water tank is equipped with a water quality detector. When the oil content in the water exceeds the set value, the integrated electronic control display system opens the electronically controlled drain valve and the electronically controlled water supply valve to discharge the sewage before adding new water.

[0009] The water tank is equipped with an evaporator for an air conditioning compressor to lower the water temperature. In hot seasons, the air conditioning compressor can be turned on to generate low-temperature water spray to remove oil fumes. This not only enhances the oil removal effect but also absorbs the heat generated by the stove combustion in the oil fumes. The air is then cooled down by the oil spray and becomes low-temperature clean air, which is then blown back into the kitchen to lower the kitchen temperature.

[0010] The condenser of the air conditioner refrigeration compressor is installed in a sealed insulated water tank, which can heat the water in the insulated water tank to make it the hot water commonly used for washing in the kitchen.

[0011] The insulated water tank is equipped with an electric heater, which can be turned on separately to generate hot water when the fume purification air conditioner is not in use.

[0012] The insulated water tank is equipped with a safety pressure relief valve, a temperature sensor, a hot water outlet pipe and valve, a cold water inlet pipe, and a water tank drain valve.

[0013] The aforementioned multi-functional fume purification air conditioner integrates an electronic control display system, which controls the start and stop of the centrifugal fan, submersible pump, air conditioning compressor, and electronically controlled water supply valve based on feedback signals from the water tank temperature, water level sensor, hot water temperature sensor, and machine settings.

[0014] This utility model of a multi-functional oil fume purification air conditioner can not only realize the functions of a range hood, air conditioner, and water heater needed in the kitchen, but also purify the exhaust oil fumes and utilize the waste heat of the stove to convert it into hot water commonly used in the kitchen, thus achieving the effect of multiple uses in one machine.
