To the embodiment of the present invention, modify or replace some technical features, without departing from the spirit of the present invention, it should be covered in the technical solution scope of the present invention.
The first embodiment is as follows: as shown in fig. 1, fig. 2 and fig. 3, the embodiment provides a steaming and baking device, which includes an inner container 1, an exhaust hood 2 and a fan 3, wherein the exhaust hood 2 and the fan 3 are disposed on the inner container 1, an exhaust passage is formed in the exhaust hood 2, an air outlet of the fan 3 is connected to an air inlet of the exhaust passage, a first air outlet 101 and a second air outlet 102 are disposed on the inner container 1, a partition plate 4 is disposed in the exhaust hood 2 to partition the exhaust passage into a first passage 201 and a second passage 202, the first air outlet 101 is communicated with the first passage 201, the second air outlet 102 is communicated with the second passage 202, and a first temperature and humidity sensor 5 is disposed in the second passage 202.
The steaming and baking equipment of this embodiment measures the culinary art humidity of steaming and baking equipment through the mode of diluting for high temperature, high wet steam cooling to reduce the comdenstion water on temperature and humidity sensor surface, with the temperature and humidity sensor detection precision that improves, and its simple structure, reliable and stable can prolong temperature and humidity sensor's life to a certain extent.
Specifically, the exhaust hood 2 is in a fan-shaped flat shape, the first air outlet 101 and the second air outlet 102 arranged on the liner 1 are respectively communicated with the first channel 201 and the second channel 202 formed in the exhaust hood 2, and the first channel 201 and the second channel 202 are separated by the partition plate 4 and are independent from each other, so that the steam exhausted from the first air outlet 101 and the steam exhausted from the second air outlet 102 cannot interfere with each other and mix with each other. Wherein the steam in second passageway 202 is discharged from second gas outlet 102, because exhaust hood 2 gradually becomes great for the cooling of steam dilutes greatly, and reduces the steam velocity of flow, and fan 3 blows in the exhaust port that the environment is blown out exhaust hood 2 after cooler air mixes with steam, and the temperature can be reduced by a wide margin, with this detection accuracy that can improve first temperature and humidity sensor 5.
In the present embodiment, the area of the first air outlet 101 is larger than the area of the second air outlet 102. Specifically, first gas outlet 101 is formed directly over inner bag 1 and is rectangular form, its area is great relatively, exhaust steam is more, belong to normal cooling steam port, second gas outlet 102 is formed directly over inner bag 1 and is circular equally, its area is less relatively, exhaust steam is less, be used for diluting exhaust steam cooling, in order to improve first temperature and humidity sensor 5's detection precision, can avoid first temperature and humidity sensor 5 to work under the highly compressed state of high temperature simultaneously, do benefit to the life of extension first temperature and humidity sensor 5 from this.
Preferably, the exhaust area of the first passage 201 is larger than that of the second passage 202, thereby facilitating the outward discharge of most of the steam through the first passage 201 to cool the inner container 1 normally.
In this embodiment, the cross-section of second channel 202 is flared. The steam in the second channel 202 is discharged from the second air outlet 102, because the second channel 202 gradually changes greatly, the temperature reduction and dilution of the steam are large, the flow rate of the steam is reduced, the fan 3 blows in the exhaust port of the exhaust hood 2 after the environment cold air and the steam are mixed, the temperature can be greatly reduced, the detection precision of the first temperature and humidity sensor 5 can be improved, meanwhile, the first temperature and humidity sensor 5 can be prevented from working under the high-temperature and high-pressure state, and therefore the service life of the first temperature and humidity sensor 5 is prolonged.
Further, the lower end of the first temperature and humidity sensor 5 is a tip. The steam roasting equipment of this embodiment puts through 5 sides of first temperature and humidity sensor to the lower extreme of first temperature and humidity sensor 5 is more sharp, makes the comdenstion water of condensation on 5 surfaces of first temperature and humidity sensor flow down smoothly, reduces the comdenstion water on 5 surfaces of first temperature and humidity sensor, and then reaches the purpose that improves measurement accuracy.
Furthermore, the second air outlet 102 is disposed close to the partition plate 4, and the first temperature/humidity sensor 5 is disposed on a side surface of the partition plate 4 and close to the second air outlet 102. According to the steaming and baking equipment, the first temperature and humidity sensor 5 which is laterally arranged and close to the second air outlet 102 is arranged in the second channel 202, so that the steam is greatly cooled and decelerated, the deterioration of the working environment of the first temperature and humidity sensor 5 is reduced, and the amount of condensed water on the surface of the first temperature and humidity sensor 5 is greatly reduced; and the lower extreme of first temperature and humidity sensor 5 is more sharp for the comdenstion water of condensing on first temperature and humidity sensor 5 surface can flow down smoothly, reduces first temperature and humidity sensor 5 surface comdenstion water, and both have improved first temperature and humidity sensor 5's life-span and measurement accuracy jointly.
Preferably, a first flow sensor 6 is arranged in second outlet 102 for measuring steam flow Q of second outlet 1021A second temperature and humidity sensor 7 is arranged near the fan 3 for measuring the ambient temperature and humidity and obtaining the ambient absolute humidity P2A second flow sensor 8 is arranged in the second passage 202 at a position close to the first temperature and humidity sensor 5 for measuring the steam flow Q at the exhaust port of the exhaust hood 23The first temperature and humidity sensor 5 is used for measuring the temperature and humidity of the second air outlet 102 and obtaining the absolute humidity P of the second air outlet3。
Further, the absolute humidity P of the inner container1Obtained by the following formula:
by the formula:
the derivation shows:
obtaining the absolute humidity P of the inner container1Then, according to the relation of the temperature of the inner container, the absolute humidity and the relative humidity, the temperature of the inner container and the absolute humidity P of the inner container are known1On the premise of (1), the relative humidity U of the inner container can be obtained by looking up a table.
In conclusion, the steaming and baking device of the embodiment obtains the absolute humidity P of the environment2And the absolute humidity P of the second air outlet3And a second outlet 102 steam flow rate Q1Exhaust port steam flow Q3The absolute humidity P of the liner can be calculated1Thereby realizing the indirect detection of the cooking humidity of the inner container. Therefore, the condition that the temperature and humidity sensor is exposed in the high-temperature and high-humidity environment of the inner container of the steaming and baking equipment for a long time to cause short service life can be avoided.
Example two: as shown in fig. 1, fig. 2 and fig. 3, the present embodiment provides a control method of a steaming and baking apparatus, which is applied to the steaming and baking apparatus according to the first embodiment, and the control method includes the following steps:
s101, starting steaming and baking equipment;
s102, judging whether the steaming and baking equipment is in a preheating stage, if so, turning to S103, and if not, turning to S104;
s103, controlling the first temperature and humidity sensor 5 to stop working;
s104, judging whether the evaporator and/or the electric heating tube work, namely judging whether one or more of the evaporator and the electric heating tube work, if at least 1 of the evaporator and the electric heating tube is in a working state, turning to the step S105, and if the evaporator and the electric heating tube are not in a working state, turning to the step S103;
s105, controlling the first temperature and humidity sensor 5 to measure the temperature and humidity of the second air outlet 102;
s106, measuring the absolute humidity P of the second air outlet3Passes to the control system, and proceeds to step S102.
The control method of the steaming and baking equipment is simple, low in cost and capable of prolonging the service life of the temperature and humidity sensor to a certain extent.
Specifically, when the inner container 1 is in the preheating stage, the first temperature and humidity sensor 5 does not work; when the temperature of the liner reaches the set temperature, because the evaporator in the steaming mode and the electric heating pipe in the mode work intermittently, when the evaporator and the electric heating pipe do not work, the discharged steam is less, and the measurement precision can be reduced, so that the temperature and humidity measurement is carried out by the first temperature and humidity sensor 5 when more than one of the evaporator and the electric heating pipe work, the measurement precision is improved, and the service life of the temperature and humidity sensor is prolonged.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
