Problems solved by technology

[0002] At present, the humidity detection function is rarely used in household steam ovens, mainly because the humidity sensor exposed to the inner tank of the steam oven is exposed to high temperature and high humidity for a long time, and the service life is short. Many humidity sensors need to be replaced within a year, and the cost remains high.
And often because the condensed water condenses on the surface of the humidity sensor, the measured humidity is inaccurate, which affects the taste of cooking and reduces the user experience
Or a relatively high-end humidity sensor, resistant to high temperature and high humidity environment, but the cost is higher
In addition, the detection accuracy of the humidity sensor is often affected by the air flow velocity, and the air with a faster flow velocity often leads to inaccurate humidity detection.

Embodiment 1

[0035] See attached Figure 1-5 Shows a cooking device 1 with an absolute humidity sensor 9 according to the present invention, including a cooking device inner cavity 2, an exhaust hood 3 and a fan 4, and the exhaust hood 3 and the fan 4 are arranged in the cooking device On the chamber 2, the exhaust hood 3 has an exhaust hood channel 31 through front and back, the air outlet of the fan 4 communicates with the intake end of the exhaust hood channel 31, and the exhaust hood channel 31 An exhaust port is provided between the inner cavity 2 of the cooking equipment, and a partition 5 is arranged in the passage of the exhaust hood 3, and the partition 5 divides the passage of the exhaust hood 3 into at least two passages, Including a first exhaust hood channel 32 and a second exhaust hood channel 33, the exhaust port includes a first exhaust port 6 and a second exhaust port 7, the first exhaust port 6 and the second exhaust port One end of the exhaust port 7 communicates with t...

Embodiment 2

[0042] See attached Image 6 It shows a control method of a cooking device with an absolute humidity sensor of the present invention, which is applied to a cooking device with an absolute humidity sensor in Embodiment 1, and the control method includes the following steps:

[0043] The cooking device S1 is started; after the cooking device is started, the cooking device is preheated, that is, the temperature of the inner cavity of the cooking device is gradually increased.

[0044] Judging whether the cooking equipment has been preheated S2; if the cooking equipment has not been preheated, continue to preheat the cooking equipment.

[0045] If the preheating of the cooking equipment is completed, the evaporator is controlled to work at the maximum power S3; after the preheating is completed, the temperature of the inner cavity of the cooking equipment reaches the temperature setting value and stabilizes at the temperature setting value. In this embodiment, five humidity level...

Abstract

The present invention proposes a cooking device with an absolute humidity sensor and a control method thereof. A partition is provided in the exhaust hood passage, and the partition divides the exhaust hood passage into at least two passages, including the first An exhaust hood channel and a second exhaust hood channel, the exhaust port includes a first exhaust port and a second exhaust port, one end of the first exhaust port and the second exhaust port are respectively connected to the The inner cavity of the cooking equipment is communicated, the other end of the first exhaust port communicates with the first exhaust hood channel, the other end of the second exhaust port communicates with the second exhaust hood channel, and The rear end of the first exhaust hood channel is provided with a baffle, and the baffle is used to prevent the wind blown by the fan from entering the first exhaust hood channel, and an absolute humidity sensor is arranged inside the baffle . The influence of high temperature and high humidity in the inner cavity of the cooking equipment on the absolute humidity sensor is avoided. The absolute humidity sensor has a long service life and can accurately obtain the humidity value of the inner cavity of the cooking equipment.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a cooking device with an absolute humidity sensor and a control method thereof. Background technique [0002] At present, the humidity detection function is rarely used in household steam ovens, mainly because the humidity sensor exposed to the inner tank of the steam oven is exposed to high temperature and high humidity for a long time, and the service life is short. Many humidity sensors need to be replaced within a year, and the cost remains high. . And often because the condensed water condenses on the surface of the humidity sensor, the measured humidity will be inaccurate, which will affect the taste of cooking and reduce the user experience. Or a relatively high-end humidity sensor, which is resistant to high temperature and high humidity environments, but the cost is relatively high. In addition, the detection accuracy of the humidity sensor is often affected...
