At present, after steam cooking equipment starts, because the heating piece needs time to heat up, and then influence the production rate of high temperature steam, lead to cooking time longer, influence cooking efficiency.

In order to solve the above problems, as shown in fig. 3 to 6, a water inlet portion 201 is provided with a water inlet flow passage 21, and a water outlet portion 202 is provided with a first flow passage 22 and a second flow passage 23 which are communicated to the water inlet flow passage 21; the first flow passage 22 and the second flow passage 23 are arranged at intervals and are communicated with the heating cavity 7; 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. Wherein the first and second baffles 76 are specifically configured to separate the steam outlet 73 from the first and second outlets 221 and 231, and the direction of water flow within the adapter 2 is specifically indicated by arrow a in fig. 6.

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 member 3 starts to heat, since the temperature of the heating member 3 cannot meet the requirement of generating a large amount of steam at this time, the adjusting device switches the water inlet flow passage 21 in the adapter 2 to communicate with the first flow passage 22, since the sectional area of the single first outlet 221 of the first flow passage 22 is smaller than the sectional area of the second outlet 231 of the second flow passage 23, the fluid in the water inlet flow passage 21 can be sprayed on the heating member 3 in a state of being faster and more than one, that is, the fluid can be sprayed on the heating member 3 in a dispersed form at this time, so that the heating member 3 can consume little heat in a state of not being higher in heating temperature to quickly convert the fluid sprayed from 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 be communicated with the water inlet flow passage 21 and 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 form, 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, high-temperature steam required for cooking can be rapidly generated, the rate of steam generation is improved, the cooking time period is shortened, and the cooking efficiency can be improved; the ejected fluid may be water or mist.

That is, the first flow passage 22 is used to spray the dispersed fluid to the heating element 3 when the heating temperature of the heating element 3 is lower than the preset temperature, and the second flow passage 23 is used to spray the concentrated fluid to the heating element 3 when the heating temperature of the heating element 3 is higher than the preset temperature, so that the dispersed fluid or the concentrated fluid 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.

It should be noted that, when the heating temperature of the heating element 3 is low, the dispersed fluid 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 direct water spraying 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 water quantity required for generating the high-temperature steam cannot be met due to the fact that the fluid sprayed in a dispersed manner is not capable of meeting the water quantity required for generating the high-temperature steam, or the fluid sprayed in a dispersed manner cannot prevent the heating element 3 from further increasing in temperature, namely, a large amount of fluid is required to be added into the heating element 3, so that the fluid quantity required for generating the steam can be met, and smooth generation of the high-temperature steam is ensured; on the other hand, the fluid can control the temperature of the heating element 3, so that the heating element 3 can be always in a proper temperature range.

As shown in fig. 4 to 6, one end of the water inlet flow channel 21 can extend to the outside of the main housing 1, and the water inlet flow channel 21 can be externally connected with a fluid source, so that the fluid source can directly provide fluid to the water inlet flow channel 21 through a rubber tube; and, at least part of the first outlet 221 of the first flow passage 22 and the second outlet 231 of the second flow passage 23 is disposed higher than the heating member 3 to facilitate the first outlet 221 to spray the dispersed fluid toward the heating member 3 and the second outlet 231 to spray the concentrated fluid toward the heating member 3.

Further, as shown in fig. 4, the adjusting device includes a driving member 61 and an adjusting member 62, the adjusting member 62 is at least partially inserted into the adapter 2, and the adjusting member 62 is capable of moving relative to the adapter 2 under the driving of the driving member 61, so that the adjusting member 62 is capable of selectively communicating the water inlet flow passage 21 with the first flow passage 22 or the water inlet flow passage 21 with the second flow passage 23. The driving member 61 may be a rotary structure or a push structure, which is not limited herein.

As shown in fig. 4 to 6, the adaptor 2 has a receiving hole 24 for receiving an adjusting member 62, the receiving hole 24 is located between the water inlet flow passage 21 and the first flow passage 22/the second flow passage 23, the adjusting member 62 is movable in the receiving hole 24, and a movement direction of the adjusting member 62 is disposed at an angle to a flow direction of the fluid in the water inlet flow passage 21 so as to be able to selectively communicate the water inlet flow passage 21 with the first flow passage 22 or the water inlet flow passage 21 with the second flow passage 23 by a movement of the adjusting member 62.

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.

In other embodiments, the adjusting member 62 may further include a connection portion and a flow portion, where the connection portion is in driving connection with the driving member 61; the driving member 61 can rotate the circulating portion in the accommodating hole 24 and stay in the first position or the second position; when the circulation part is at the first position, the water inlet flow channel 21 is at least communicated with the first flow channel 22 through the circulation part; when the flow-through portion is in the second position, the water inlet flow passage 21 communicates with at least the second flow passage 22 through the flow-through portion, that is, the regulating member 62 is capable of rotational movement within the accommodating hole 24.

Further, as shown in fig. 4 to 6, 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 fluid sprayed from the first outlets 221 can be sprayed onto the heating element 3 comprehensively, and better reducing the loss in the heat transfer process.

Specifically, along the flow direction of the fluid in the first flow passage 22, there is an area of increased cross section in the first flow passage 22 in the area continuous with the first outlet 221, even if the entire first outlet 221 is provided in a horn-like structure, when six pieces of the fluid enter from the inlet end of the first outlet 221, the fluid can be spread to both sides at the same time, so that the fluid dispersed from the outlet end of the first outlet 221 can be sprayed on the heating member 3 in a dispersed manner, and further, the fluid dispersed from the first outlet 221 can be better ensured to be spread on the heating member 3 in a comprehensive manner.

It should be noted that, as shown in fig. 5 and fig. 7, the outlet end of the first outlet 221 may have a circular structure (fig. 5) or an elongated structure (fig. 7), and the specific shape of the outlet end of the first outlet 221 is not limited herein.

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 fluid 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, when the sprayed dispersion fluid cannot meet the amount required by steam generation or the dispersion fluid cannot prevent further temperature rise of the heating element 3, the plugging portion of the adjusting element 62 moves and stays at the second position, and at this time, the water inlet flow channel 21 is communicated with the second flow channel 23 through the flow portion of the adjusting element 62; thereafter, the water in the water inlet flow passage 21 is directly and largely injected in a centralized form on the heating element 3 through the second flow passage 23 so that the water can be largely injected to the heating element 3 in a centralized fluid form, so that the heating element 3 can rapidly convert the fluid 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.

Wherein, the high temperature steam generated by the heating gasification of the heating member 3 can sequentially pass through the free end of the second partition plate 76, the gap between the second partition plate 76 and the first partition plate 751, and the free end of the first partition plate 751 and then enter the steam outlet 73, so that the high temperature steam in the steam outlet 73 enters the inner container of the functional box body for steam cooking of food.

The first partition plate and the second partition plate 76 can have better blocking effect on the steam outlet 73 and the first outlet 221 and the second outlet 231; in the process of steam flow, a large amount of water in the high-temperature steam can be filtered on the two partition plates, so that the water-vapor separation in the steam can be better realized; meanwhile, water drops formed by water in the steam flowing to the two clapboards can automatically flow back into the heating cavity 7 through the reflux port 753 and the free end of the second clapboards 76 respectively, so that the recycling of water resources is ensured.

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.
