Description

TECHNICAL FIELD

[0001] The utility model relates to a refrigeration type range hood, especially a condensate water treatment system of refrigeration type range hood. BACKGROUND

[0002] Various refrigeration type range hoods are disclosed in the prior art, which increase air conditioning components on the basis of range hood platform, can realize all functions of range hood, and can realize the function of air conditioner. The air conditioning components include an inner machine module and an outer machine module, wherein the inner machine module includes an evaporator and an inner machine fan, and the outer machine module includes a condenser and an outer machine fan. Some refrigeration type range hoods install the condenser of the air conditioning components in the smoke exhaust channel, and the condenser will be polluted by oil fume, needs to be cleaned in time, and if not cleaned in time, the heat exchange effect will be greatly reduced, and then the air conditioning efficiency will be affected, resulting in the increase of energy consumption, and the condenser also needs to be cooled by the oil fume fan when working in the refrigeration mode. Although some refrigeration type range hoods install the condenser outside the smoke exhaust channel, dirt will also remain on the surface of the condenser after long-term work, and the condenser needs to be cleaned to ensure the heat exchange effect. In addition, since the refrigeration range hood is installed in the kitchen oil fume environment, and the return air of the inner machine module is usually indoor return air, dust and oil stains will remain on the surface of the evaporator after long-term use, and the evaporator also needs to be cleaned in time. For example, the water pump flow control system and air conditioning type range hood disclosed in the Chinese utility model patent with the patent number 202220040537.0 (the authorized public number is CN 217685714U) work in the air conditioning mode (refrigeration mode), the condensate water condensed on the evaporator flows into the water pan, the condensate water in the water pan flows into the water box through the water inlet pipe, the condensate water in the water box is transported to the liquid distributor through the water outlet pipe under the action of the water pump, and then flows to the surface of the condenser from the liquid distributor, which can cool the condenser, further improve the heat exchange effect, realize the effective utilization of condensate water, and evaporate the condensate water heated by the condenser from the first smoke exhaust channel. The condensate water that is not evaporated flows into the water box, and then flows back to the water box through the backwater pipe for repeated use. The air conditioning type range hood can only clean the condenser, and the cleaned sewage is not discharged separately, but accumulated in the water storage box. When the water pump works again, the sewage will block the water pump, causing damage to the water pump, and the accumulation of sewage in the water storage box will also cause odor. In view of the above, the condensate water treatment system of the existing refrigeration type range hood needs to be further improved. UTILITY MODEL CONTENTS

This will not clog the water pump and cause damage to the water pump. In addition, wastewater will not accumulate in the water storage box and will not produce odors. Attached Figure Description
