In order to make the technical problems solved, the technical scheme adopted and the technical effects achieved by the utility model more clear, the technical scheme of the utility model is further described below by a specific embodiment in combination with the attached drawings.

At present, after the steam cooking equipment is started, the heating pipe needs time to be heated, so that the steam generation rate is affected, the cooking time is longer, and the cooking efficiency is affected.

For this reason, a steam generator, a functional case including the steam generator, and an integrated cooker including the steam generator are proposed in the present embodiment, and the functional case can be applied to the integrated cooker; the steam generator in the embodiment can realize the rapid generation of high-temperature steam, improve the steam generation rate, shorten the cooking time length and further improve the cooking efficiency. The functional box body can be a steam box or a steam oven.

Specifically, as shown in fig. 1 to 4, the steam generator includes a main casing 1, and an adapter 2 and a heating member 3 provided in the main casing 1; the adapter 2 comprises a water inlet part and a water outlet part, wherein the water inlet part is provided with a water inlet flow channel 21, and the water outlet part is provided with a first flow channel 22 and a second flow channel 23 which are communicated with the water inlet flow channel 21; the first flow passage 22 and the second flow passage 23 are arranged at intervals and are communicated with the cavity where the heating element 3 is positioned; the first flow channel 22 comprises at least one first outlet 221, the cross-sectional area of the individual first outlets 221 of the first flow channel 22 being smaller than the cross-sectional area of the second outlets 231 of the second flow channels 23; and, the steam generator further comprises an adjusting device arranged in the main housing 1 for switching the communication of the water inlet flow passage 21 in the adapter 2 with the first flow passage 22 or the communication of the water inlet flow passage 21 in the adapter 2 with the second flow passage 23. The direction of water flow in the adapter 2 is specifically shown by arrow a in fig. 4.

As shown in fig. 2, one end of the water inlet channel 21 can extend to the outside of the main housing 1, and the water inlet channel 21 can be externally connected with a fluid source, so that the fluid source can directly provide fluid to the water inlet channel 21 through a rubber tube. In this embodiment, the heating element 3 is specifically a heating tube, and the fluid may be water.

Compared with the prior art, the structure of the adapter 2 is changed, and the adapter 2 and the adjusting device are mutually matched for use; when the heating element 3 starts to heat, the heating element temperature cannot meet the requirement of generating a large amount of steam, the adjusting device switches the water inlet flow channel 21 in the adapter 2 to be communicated with the first flow channel 22, and the cross section area of the single first outlet 221 of the first flow channel 22 is smaller than that of the second outlet 231 of the second flow channel 23, so that the fluid in the water inlet flow channel 21 can be sprayed on the heating element 3 in a state of high speed and multiple strands, that is, the fluid can be directly sprayed on the heating element 3 in a dispersed water column mode, so that the heating element 3 can consume little heat under the state of low heating temperature to quickly convert the fluid sprayed by the first outlet 221 into high-temperature steam for quick cooking; when the heating element 3 is continuously heated to a temperature which can meet the requirement of generating a large amount of steam, the adjusting device is switched to communicate the water inlet flow passage 21 with the second flow passage 23 in the adapter 2, and at the moment, the fluid in the water inlet flow passage 21 can be sprayed on the heating element 3 at a slower speed and in a large amount through the second flow passage 23, that is, the fluid can be sprayed on the heating element 3 in a centralized water column form in large amount, so that the heating element 3 can quickly convert a large amount of fluid into high-temperature steam for cooking; in the above manner, by changing the state of the fluid sprayed to the heating member 3 at different heating temperatures, it is possible to rapidly generate steam required for cooking, increase the rate of steam generation, shorten the cooking time period, and thus it is possible to improve the cooking efficiency.

That is, the first flow path 22 is used to spray the dispersed water column to the heating element 3 when the heating temperature of the heating element 3 is lower than the preset temperature, and the second flow path 23 is used to spray the water column to the heating element 3 when the heating temperature of the heating element 3 is higher than the preset temperature, so that the dispersed water column or the concentrated water column can be selectively sprayed to the heating element 3 according to the heating temperature of the heating element 3. The preset temperature of the heating element 3 is a temperature at which the heating element 3 can generate enough high-temperature steam when the adapter 2 is communicated with the second flow channel 23, and the preset temperature needs to be determined according to specific power and cooking conditions of the heating element 3, which is not limited herein.

It should be noted that, when the heating temperature of the heating element 3 is low, the dispersed water column is directly sprayed to the heating element 3, so that the heating element 3 consumes less heat to convert the fluid into high-temperature steam, and the problem that the high-temperature steam cannot be generated quickly due to the fact that the water is directly sprayed to the heating element 3 when the heating temperature of the heating element 3 is low is avoided; when the heating temperature of the heating element 3 is continuously increased to be higher than the preset temperature, the fluid sprayed by the dispersed water column cannot meet the water quantity required by generating high-temperature steam at the moment, or the fluid sprayed by the dispersed water column cannot prevent the heating element 3 from further temperature increase at the moment, that is, a large amount of water needs to be added into the heating element 3, so that on one hand, the water can meet the water quantity required by generating steam and the smooth generation of the steam is ensured; on the other hand, the water can control the temperature of the heating element 3, so that the heating element 3 can be always in a proper temperature range.

Further, the adjusting member 62 includes a connection portion, a blocking portion, and a flow portion, and the connection portion is in transmission connection with the driving member 61; the driving piece 61 can move the blocking portion toward or away from the bottom wall of the accommodating hole 24 and stay at the first position or the second position; when the plugging part is at the first position, the water inlet flow channel 21 is at least communicated with the first flow channel 22 through the circulating part; when the blocking part is in the second position, the water inlet channel 21 is at least in communication with the second channel 23 via the flow-through part, i.e. the adjusting member 62 is capable of reciprocating in the receiving hole 24.

Wherein, the inner wall surfaces of the upper and lower shells of the heating element 3 are coated with a coating which is not easy to adhere to water, so as to avoid water remaining on the heating element 3 and the lower shell and easily forming scale and dirt.

Further, as shown in fig. 2 to 4, the first outlets 221 of the first flow channels 22 include a plurality of first outlets 221 and are arranged at intervals, and the first outlets 221 are directed to the heating element 3, that is, the first outlets 221 are arranged obliquely downwards in a direction close to the heating element 3, so as to shorten the spraying distance between the heating element 3 and the first flow channels 22, thereby ensuring that the dispersed water column sprayed from the first outlets 221 can be fully scattered on the heating element 3, and better reducing the loss in the heat transfer process.

Specifically, along the flow direction of the fluid in the first flow channel 22, there is a region of increased cross section in the first flow channel 22 in a region continuous with the first outlet 221, even if the entire first outlet 221 is provided in a horn-like structure, six pieces of water columns dispersed to both sides can be simultaneously spread after entering from the inlet end of the first outlet 221, so that the dispersed water columns at the outlet end of the first outlet 221 can be sprayed on the heating element 3 in a dispersed manner, and further, it can be better ensured that the dispersed water columns sprayed from the first outlet 221 can be scattered on the heating element 3 in a comprehensive manner.

The specific working procedure of the steam generator in this embodiment is as follows:

firstly, the steam generator starts to work, at the moment, the heating temperature of the heating element 3 is rapidly increased, but the heating temperature is lower than the preset temperature, and meanwhile, the adjusting element 62 moves relative to the adapter 2 under the driving of the driving element 61, so that the blocking part of the adjusting element 62 moves and stays at the first position, and at the moment, the water inlet flow channel 21 is communicated with the first flow channel 22 through the circulation part of the adjusting element 62; thereafter, the water in the water inlet flow passage 21 is uniformly and entirely sprayed on the heating member 3 through the respective first outlets 221 of the first flow passage 22, so that the heating member 3 can rapidly convert the dispersed water column into high temperature steam for rapid cooking. Wherein the temperature detecting member 4 detects the heating temperature of the heating member 3 in real time.

As the heating temperature of the heating element 3 increases continuously, when the heating temperature of the heating element 3 exceeds the preset temperature, that is, the fluid sprayed through the distributed water column cannot meet the amount required by steam generation at the moment, or the fluid sprayed through the distributed water column cannot prevent the heating element 3 from further increasing in temperature, the blocking part of the adjusting element 62 moves and stays at the second position, and at the moment, the water inlet flow channel 21 is communicated with the second flow channel 23 through the circulation part of the adjusting element 62; thereafter, the water in the water inlet flow passage 21 is directly and largely sprayed on the heating member 3 through the second flow passage 23 so that the water can be largely sprayed to the heating member 3 in the form of a concentrated water column, so that the heating member 3 can rapidly convert the water into high temperature steam.

Wherein, in the process of spraying water on the second runner 23, a part of water can be heated and gasified by the heating element 3 to form high-temperature steam, and another part of water can be accumulated in the heating cavity 7 so as to cool the heating element 3, thereby avoiding the heating temperature of the heating element 3 from further increasing and ensuring that the heating temperature of the heating element 3 is always in a proper temperature range.

The generated high temperature steam then enters the steam outlet 73 through the free end of the second partition plate 752, so that the high temperature steam in the steam outlet 73 enters the steam box inner container for steam cooking of the food.

Meanwhile, in the whole working process of the steam generator, the water level detection piece 5 can detect the water level in the heating cavity 7 in real time, so that the water level in the heating cavity 7 is always kept to be a preset water level, and the situation that the water level is too high to consume a large amount of electric energy of the heating piece 3 is avoided, so that the electric energy loss of the heating piece 3 can be reduced.

After that, when the cooking is about to be finished, water is not sprayed into the heating chamber 7 through the second outlet 231, so that the heating member 3 directly heats the water at a preset water level, thereby maximizing the use of the water in the heating chamber 7.

Finally, after the cooking is finished, the water level detecting member 5 is made to detect whether the heating cavity 7 has residual water, and if so, the drain passage 74 on the lower housing is opened to drain the residual water and scale impurities in the heating cavity 7 out of the whole main housing 1.

The foregoing is merely exemplary of the present utility model, and those skilled in the art should not be considered as limiting the utility model, since modifications may be made in the specific embodiments and application scope of the utility model in light of the teachings of the present utility model.
