Steam exhaust structure for cooking device and cooking device with same

Abstract

The invention relates a steam exhaust structure for a cooking device, which comprises an inner container and a water tank, the water tank is internally provided with a water purification cavity and a waste water cavity which are separated through a heat conduction filtering layer, and when a certain internal pressure difference is formed between the waste water cavity and the water purification cavity, water in the waste water cavity tends to flow towards the water purification cavity through the heat conduction filtering layer; the inner container is provided with a first exhaust port, the waste water cavity is provided with a waste steam inlet, and the waste steam inlet is in fluid communication with the first exhaust port. Cooking waste steam in the inner container enters the waste water cavity, the humidity of the inner container can be reduced in the baking mode, and therefore the baking quality is improved. Steam in waste gas entering the waste water cavity is condensed through cold water in the water purification cavity to form condensate water, the condensate water is filtered through the heat conduction filter layer under the action of the pressure difference between the waste water cavity and the water purification cavity and then enters the water purification cavity, and the return water utilization of cooking waste water is achieved. In addition, the water in the water purification cavity can be preheated through the high temperature of waste steam entering the waste water cavity, and the cooking efficiency is improved.

Description

technical field [0001] The invention relates to the field of cooking devices, in particular to a steam exhaust structure for the cooking device and the cooking device with the structure. Background technique [0002] In order to make full use of the kitchen space, the current cooking device tends to be integrated, that is, the same cooking device integrates multiple cooking functions, such as a baking function, steaming function or microwave function. The structural limitation of the integrated cooking device makes it have the following problems when using different cooking functions: (1) After the baking mode ends, the inner tank remains at a high temperature for a certain period of time. At this time, if the steaming mode is used directly, the The working environment temperature of the inner heating plate is too high, which affects its service life. Therefore, the existing cooking device integrated with steaming and baking needs to cool down for a period of time after usin...

AI Technical Summary

Problems solved by technology

The structural limitation of the integrated cooking device makes it have the following problems when using different cooking functions: (1) After the baking mode ends, the inner tank remains at a high temperature for a certain period of time. At this time, if the steaming mode is used directly, the The working environment temperature of the inner heating plate is too high, which affects its service life. Therefore, the existing cooking device integrated with steaming and baking needs to cool down for a period of time after using the baking mode before continuing to use the steaming mode, which seriously affects the user. experience

(2) Instant humidification is required when baking some foods (such as baking European bread, etc.), but the existing cooking devices generally do not have instant humidification function, which affects the cooking effect

(3) When cooking some food, excessive humidity inside the inner pot will seriously affect the shape of the food and inner pot organization (such as baking chiffon cakes, puffs, etc.). High, so it is necessary to use a high-temperature pump or reduce the temperature of the extracted gas, and the high-temperature pump is large and expensive, not suitable for cooking devices, and it is troublesome to cool the extracted gas

(4) Although some existing cooking devices are equipped with waste water tanks for collecting cooking waste water, the waste water collected in the waste water tanks is generally not recycled, but directly dumped
