Illustratively, the phase change temperature of the phase change material disposed within the thermal storage container at cooktop subsystem 30 is greater than or equal to 100 degrees. For convenience of description, the heat storage container disposed at the range subsystem 30 may be referred to as a third heat storage container, and the phase change material in the heat storage container may be referred to as a third phase change material, that is, the phase change temperature H3 of the third phase change material may be H3 ≧ 100 ℃, and the phase change temperature H3 mainly refers to a phase change temperature at which the third phase change material changes from a gel state, a semi-solid state, or a solid state to a liquid state.

In some embodiments, the phase change material that absorbs the excess heat may also change from a liquid state to a gaseous state.

In some embodiments, the phase change material that absorbs the waste heat and undergoes phase change may not circulate along the waste heat pipeline 41, for example, the waste heat absorbed by the phase change material may flow through the waste heat exchanger 44 along the waste heat pipeline 41, that is, the waste heat absorbed by the phase change material may be separately collected and the air flow carrying the waste heat may flow through the waste heat exchanger 44 along the waste heat pipeline 41, and the phase change material is always stored in the heat storage container regardless of its form.

In one embodiment, referring to fig. 1, the smoke exhaust subsystem 20 further includes a smoke purifying assembly 23, and the smoke purifying assembly 23 is disposed in the smoke exhaust duct 21.

The oil smoke purification component 23 can purify and/or adsorb the oil smoke in the air duct 21 of the smoke machine, so as to reduce the emission of the oil smoke and reduce the pollution to the atmosphere.

Illustratively, the lampblack purification component 23 may be one of a lampblack collision separator, a plasma purifier, an ozone emitter, an ultraviolet lamp and a filter component, and may also be a combination of at least two of the lampblack collision separator 231, the plasma purifier, the ozone emitter, the ultraviolet lamp and the filter component.

For example, referring to fig. 2 to 4, the soot impact separator 231 includes a first filter assembly 2311 having an airflow inlet 2311a and a second filter assembly 2312 having an airflow outlet 2312a, in order to improve soot separation effect, the first filter assembly 2311 is generally provided with a plurality of airflow inlets 2311a, the plurality of airflow inlets 2311a are spaced apart, the second filter assembly 2312 is generally provided with a plurality of airflow outlets 2312a, the plurality of airflow outlets 2312a are spaced apart, the first filter assembly 2311 and the second filter assembly 2312 are spaced apart, the plurality of airflow outlets 2312a and the plurality of airflow outlets 2312a are staggered, and an oil-water collecting space 231a is formed at a space between the first filter assembly 2311 and the second filter assembly 2312.

During cooking, the airflow with the oil smoke and the water vapor is introduced into the oil-water collecting space 231a from the airflow inlet 2311a and flows out from the airflow outlet 2312a, and because the airflow inlet 2311a is staggered with the airflow outlet 2312a, at least part of the airflow entering the oil-water collecting space 231a collides with the second filter assembly 2312 before flowing out from the airflow outlet 2312a and is condensed on the second filter assembly 2312 to form oil and water condensate, so that the oil smoke and the water vapor which are included in the airflow can be separated.

The filter assembly can be a filter screen or a filter element, the filter screen and the filter element can be provided with a catalyst with a purification function, the type of the catalyst can be determined according to requirements, the catalyst can be an active substance containing manganese exemplarily, and when the filter assembly is the filter element, the filter element can be made of adsorbing materials such as glass fiber felt, carbon fiber and active carbon.

When the smoke machine subsystem 20 of the kitchen air conditioning system is provided with the lampblack purification assembly 23, the kitchen air conditioning system can provide comfortable and healthy cooking environment for users while having an energy-saving effect by being matched with the air conditioning subsystem 10 and the waste heat recovery subsystem 40.

In a specific embodiment, the smoke collision separator 231 and the plasma purifier are arranged in the smoke exhaust duct 21, under the combined action of the smoke collision separator 231 and the plasma purification, the oil-fat separation degree is greater than 85%, the removal rate of the non-methane total hydrocarbons is greater than 60%, and the air flow purified by the smoke purification assembly 23 meets the emission requirement of the national standard GB/T17713-plus 2011.

The various embodiments/implementations provided herein may be combined with each other without contradiction.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application are included in the protection scope of the present application.
