Problems solved by technology

[0005] (2) When the baking (hot air convection) function is working, the temperature in the oven cavity needs to rise rapidly, and the food is baked at high temperature to achieve the effect of charred outside and tender inside. When there are air inlets and outlets on the wall of the oven cavity, the air circulation It will take away the high-temperature air in the furnace, the temperature in the furnace cavity rises slowly, consumes a lot of energy, the time of baking food will be longer, and the energy loss will be large
[0006] (3) When the steam function is working, high-temperature steam needs to be kept in the cavity to steam food. Similarly, when the air in the cavity and the outside air are circulated and exchanged, the high-temperature steam cannot remain in the cavity, and it takes a long time to steam the food.

Embodiment 1

[0035] Micro-steaming and baking all-in-one machine, using the baking function, if the air inlet and outlet are freely open, it will take 8 minutes for the temperature of the oven cavity to rise to the required 200 degrees, and during the entire cooking process, a large amount of heat will be lost with the air exchange; if Use the valve to close the air inlet and outlet, and it only takes 6 minutes for the temperature to rise to 200 degrees, which can save 25% of time and energy, and can reduce 80% of the energy loss caused by the air exchange inside and outside the furnace cavity during the whole process. At the same time, if the temperature of the furnace chamber is set to reach 200 degrees in 8 minutes, the state of closing the air inlet and air outlet can directly reduce the power of the heating tube by 20% compared with the open state, saving energy.

Embodiment 2

[0037] Micro-steaming and baking integrated machine, using the baking function to bake pizza, requires the oven cavity temperature to be 190 degrees in the early stage, and requires a temperature of 140 degrees in the middle and later stages. If the heating tube stops working, it will take 3 minutes to cool down naturally. When the air duct valve system switches the air route from the closed state to the open state, air circulation is formed in the oven cavity, and it only takes 1 minute to cool down, which saves time and improves the softness inside the pizza.

Abstract

The invention discloses an air channel valve and a microwave, steaming and baking integrated machine with the air channel valve. The air channel valve comprises a valve bracket, valve blades and a stepping motor, wherein clamping grooves are arranged in the side wall of one end of the valve bracket, one ends of the valve blades are mounted in the clamping grooves, the valve blades and the clampinggrooves are rotatably connected, one ends, far away from the clamping grooves, of the valve blades are connected with the output ends of the stepping motor, the output ends of the stepping motor areinserted in holes at one ends of the valve blades, the stepping motor drives the valve blades to rotate, the rotation axes of the valve blades under the driving of the stepping motor are positioned atthe lower sides of the valve blades, so that no large rotation space needs to be reserved on the valve bracket when the valve blades rotate, and the stepping motor is fixedly mounted on the valve bracket. According to the air channel valve and the microwave, steaming and baking integrated machine with the air channel valve, the energy exchange inside and outside a furnace chamber during the baking or steaming process can be reduced, the work efficiency can be improved, and the waste of energy is reduced.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an air path valve and an integrated micro-steaming and baking machine with the device. Background technique [0002] The current household cooking appliances are divided into microwave ovens, microwave oven integrated machines, microwave steam oven integrated machines, micro steam oven integrated machines, etc. [0003] That is, different combinations of the three functions of microwave, baking (hot air convection), and steaming. At the same time, if you want to have a good cooking effect, when using three different functions to cook food, you have different requirements on whether or not the oven cavity needs air intake, the amount of air intake, and even the timing of the intake air. [0004] (1) When the pure microwave function is working, a large amount of water vapor will be generated when microwave food is used. In order to prevent the water vapor in the oven ...
