Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a water tank structure for a range hood and the range hood. Background Art

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It uses the negative pressure generated by its internal fan system to suck the fumes generated by cooking into the range hood shell, separate and purify the fumes inside the shell, and then discharge them from the smoke outlet on the top of the shell.

[0003] When cooking, the ambient temperature in the kitchen is relatively high. In order to improve the cooking experience, people have designed refrigeration range hoods. Existing refrigeration range hoods usually add air-conditioning components on the basis of the range hood platform, which can realize all the functions of the range hood and the functions of the air conditioner. Specifically, the Chinese utility model patent "A range hood with refrigeration function" with patent number 202321058284.0 (authorization announcement number CN220038575U) includes an oil fume suction module and a refrigeration module. The oil fume suction module has a casing, an oil fume channel is provided in the casing, and a first smoke exhaust pipe connected to the oil fume channel is installed on the top of the casing. The compressor, condenser and evaporator of the refrigeration module are connected through a refrigerant pipeline. The refrigeration module is arranged on the top of the casing. The refrigeration module has a cold air channel and a heat dissipation channel. The evaporator is arranged in the cold air channel, the condenser is arranged in the heat dissipation channel, and a heat dissipation pipe is connected to the outside of the heat dissipation channel. The first smoke exhaust pipe outlet and the heat dissipation pipe outlet are respectively connected to the first inlet and the second inlet of the three-way valve, and the outlet of the three-way valve is installed with a second smoke exhaust pipe.

[0004] Since range hoods with cooling functions are generally not equipped with an external unit, effectively handling the condensed water generated during the cooling process is one of the core issues. For example, the above utility model patent uses condensed water to dissipate heat from the condenser to improve the heat exchange effect. The existing technology also directly discharges the condensed water into the oil cup at the bottom of the range hood, but this will cause users to frequently clean the oil cup, affecting the user experience.
