Description
Technical Field
The utility model belongs to the technical field of steam culinary art product, specifically provide a steam generator and cooking equipment.
Background
Current cooking apparatuses having a steam cooking function have a steam generator for heating water therein to boil and thus generating steam. Steam in the steam generator can be conveyed to a cooking cavity of the cooking equipment under the action of air pressure in the steam generator to steam food materials.
The existing steam generator generally adopts a flat bottom structure, namely, the heights of all parts of the inner bottom surface of a water container are the same. When the water-cooling steam generator works, a large amount of cold water is injected into the steam generator (particularly a water container) from the external water tank through the external water supply pump. The bottom surface of the steam generator is heated by the heating member at the bottom of the steam generator, and then the bottom surface of the steam generator is made to heat the water inside the steam generator. When the water boils, steam is generated. The more water pumped into the steam generator, the longer the time required to heat the water to boiling, which can result in a slower rate of temperature rise in the cooking chamber, thereby reducing the cooking performance of the cooking device. However, if less water is pumped into the steam generator, dry burning of the steam generator will easily occur.
In order to prevent the steam generator from dry burning, a water level sensor is generally disposed inside the steam generator. However, the inside of the steam generator is in a humid and high-temperature environment for a long time, so that the water level sensor is corroded after being used for a period of time; and the surface of the water level sensor is also coated by scale which is gradually formed along with the use, thereby influencing the accurate judgment of the water level sensor on the water level.

Optionally, the steam generator is mounted on the cooking apparatus in an inclined posture so that at least two of the temperature sensors have different heights.
Optionally, the cooking device is a steamer or a steaming and baking all-in-one machine.
Based on the foregoing description, it can be understood by those skilled in the art that, when the water in the water container is sufficient during the heating process of the water container by the heating device, the part below the liquid level of the water container directly transfers heat to the water, and the temperature is low; the part above the liquid level of the water container can not directly transfer heat to water, and the temperature is rapidly increased to be higher than the part below the liquid level of the water container. Therefore, in the foregoing technical solution of the present invention, the liquid level meter includes at least two temperature sensors disposed at intervals, and each temperature sensor is corresponding to different liquid levels of water in the water container, so that the steam generator can detect the liquid level in the water container through the at least two temperature sensors. Specifically, when the temperature of one temperature sensor suddenly increases, it indicates that the liquid level in the water container drops from above the one temperature sensor to below the one temperature sensor. Therefore, the utility model discloses a steam generator not only can accurately detect out the liquid level of water in the water containing ware through the level gauge that has two at least temperature sensor, but also avoided the water contact in level gauge and the water containing ware, and then avoided the utility model discloses a situation that the level gauge was wrapped up by the incrustation scale has guaranteed the reliability of steam generator during operation.

The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
As shown in fig. 1, in some embodiments of the present invention, the steam generator 10 comprises a water container 11, a heating device 12 and a liquid level meter 13. Wherein the water container 11 is used for holding water, the heating device 12 is used for heating the water in the water container 11, and the liquid level meter 13 is arranged outside the water container 11 and is used for detecting the liquid level of the water in the water container 11.
With continued reference to fig. 1, in some embodiments of the present invention, the heating device 12 is disposed outside the bottom wall of the water container 11, such that the heating device 12 heats the bottom wall of the water container 11, thereby heating the water in the water container 11 through the bottom wall of the water container 11.
Furthermore, in other embodiments of the present invention, the skilled person can also arrange the heating device 12 at any other feasible position of the water container 11, for example, arrange the heating device 12 inside the water container 11.
In the present invention, the heating device 12 may be any heating device such as an electric heating tube and an electric heating wire.
With continued reference to fig. 1, in some embodiments of the present invention, the liquid level gauge 13 includes at least two spaced apart temperature sensors (not labeled). The number of temperature sensors may be any feasible number, such as two, three, four, five, etc.
In the present invention, in the use state of the steam generator 10, the heights of the temperature sensors disposed at least two intervals are different. As shown in fig. 2, the water container 11 is inclined at an angle α so that the inner bottom surface of the water container 11 is inclined and the height of the temperature sensor located on the bottom wall of the water container 11 is made different. As shown in fig. 3, the top wall of the water container 11 is provided in an inclined form so that the inner bottom surface of the water container 11 is inclined, and the height of the temperature sensors located on the bottom wall of the water container 11 is made different, i.e., each temperature sensor is spaced apart from the bottom end of the water container 11 differently.
As can be understood by those skilled in the art, when the water in the water container 11 is sufficient during the heating process of the water container 11 by the heating device 12, the part below the liquid level of the water container 11 directly transfers heat to the water, and the temperature is low; however, the portion above the liquid level in the water tank 11 cannot directly transfer heat to water, and the temperature is rapidly increased to a temperature higher than the portion below the liquid level in the water tank 11. Therefore, by having the liquid level meter 13 include at least two temperature sensors spaced apart and having each temperature sensor correspond to a different level of water in the water container 11, the steam generator 10 is able to detect the liquid level in the water container 11 through the at least two temperature sensors. Specifically, when the temperature of one of the temperature sensors suddenly increases, it indicates that the liquid level in the water container 11 has dropped from above the one temperature sensor to below the one temperature sensor. Therefore, the utility model discloses a steam generator 10 not only can accurately detect out the liquid level of water in the water container 11 through level gauge 13 that has two at least temperature sensor, but also avoided the water contact in level gauge 13 and the water container 11, and then avoided the utility model discloses a reliability of steam generator 10 during operation has been guaranteed to the situation of level gauge 13 by the incrustation scale parcel.
As shown in fig. 1 and 2, in some embodiments of the present invention, the at least two temperature sensors preferably include a first temperature sensor 131 and a second temperature sensor 132. And the first temperature sensor 131 and the second temperature sensor 132 are both disposed at the outer side of the bottom wall of the water container 11 to prevent the first temperature sensor 131 and the second temperature sensor 132 from contacting the water in the water container 11, thereby avoiding the situation that the first temperature sensor 131 and the second temperature sensor 132 are wrapped by the scale when being used for a long time, and ensuring that the first temperature sensor 131 and the second temperature sensor 132 have stable use performance in the process of long-term operation of the steam generator 10.
As shown in fig. 2, in the use state of the steam generator 10, the first temperature sensor 131 is disposed at the top of the bottom wall of the water container 11, and the second temperature sensor 132 is disposed at the middle of the bottom wall of the water container 11.
In addition, in the case that the height of the first temperature sensor 131 is greater than that of the second temperature sensor 132, one skilled in the art may also dispose the first temperature sensor 131 and the second temperature sensor 132 at any other feasible positions of the water container 11 as required. For example, the first temperature sensor 131 is disposed at a position where the side wall of the water container 11 is close to the bottom wall, and the second temperature sensor 132 is disposed at the bottom wall of the water container 11.
In still other embodiments of the present invention, as shown in fig. 3, the bottom wall of the water container 11 may be inclined as required by those skilled in the art. Likewise, the first temperature sensor 131 and the second temperature sensor 132 are both provided on the water container 11, and the height of the first temperature sensor 131 is greater than the height of the second temperature sensor 132.
The operation of the level gauge 13 of the steam generator 10 according to the present invention will be briefly explained with reference to fig. 2 and 3.
It will be understood by those skilled in the art that, during the energization of the heating means 12, the portion of the water container 11 located below its internal liquid level will transfer heat directly to water when heated, and the portion of the water container 11 located above its internal liquid level will not transfer heat directly to water when heated, so that the portion of the water container 11 located above its internal liquid level is at a higher temperature than the portion of the water container 11 located below its internal liquid level. Therefore, when the temperature of the first temperature sensor 131 is detected to be higher than the temperature of the second temperature sensor 132, it is determined that the level of the water in the water container 11 is between the first temperature sensor 131 and the second temperature sensor 132.
Since in some and still other embodiments of the present invention, the first temperature sensor 131 and the second temperature sensor 132 are both arranged outside the bottom wall of the water container 11, when the level of the water in the water container 11 is located between the first temperature sensor 131 and the second temperature sensor 132, the water in the water container 11 is already less, and water needs to be added, otherwise the water container 11 will be dry-boiled by the heating device 12.
Based on this, it can be understood by those skilled in the art that when the level gauge 13 includes more temperature sensors, each of the adjacent two temperature sensors may be used to detect one level of water in the water container 11.
In other words, when the level gauge 13 includes n temperature sensors, the level gauge 13 can detect (n-1) levels of water in the water container 11.
The level gauge 13 comprises, for example, five temperature sensors. For convenience of description, the five temperature sensors are respectively referred to as a first temperature sensor, a second temperature sensor, a third temperature sensor, a fourth temperature sensor and a fifth temperature sensor in the order of increasing height. Then, the first temperature sensor and the second temperature sensor may detect the liquid level therebetween, the second temperature sensor and the third temperature sensor may detect the liquid level therebetween, the third temperature sensor and the fourth temperature sensor may detect the liquid level therebetween, and the fourth temperature sensor and the fifth temperature sensor may detect the liquid level therebetween.
Specifically, when the temperature of the first temperature sensor is higher than the temperatures of the other temperature sensors, the liquid level of the water in the water container 11 is between the first temperature sensor and the second temperature sensor. When the temperatures of the first temperature sensor and the second temperature sensor are higher than the temperatures of the other temperature sensors, the liquid level of the water in the water container 11 is between the second temperature sensor and the third temperature sensor. When the temperatures of the first temperature sensor, the second temperature sensor and the third temperature sensor are higher than the temperatures of the other temperature sensors, the liquid level of the water in the water container 11 is between the third temperature sensor and the fourth temperature sensor. When the temperatures of the first temperature sensor, the second temperature sensor, the third temperature sensor and the fourth temperature sensor are higher than the temperatures of the other temperature sensors, the liquid level of the water in the water container 11 is between the fourth temperature sensor and the fifth temperature sensor.
The operation of the steam generator 10 will be further explained with reference to fig. 4 to 5, taking a cooking device as an example. Fig. 4 is a schematic structural diagram of a cooking device according to another embodiment of the present invention, and fig. 5 is a schematic connection diagram of a local control of a cooking device according to another embodiment of the present invention.
The utility model discloses in, cooking equipment is the steam ager or evaporates roast all-in-one.

Wherein, the steam generator 10, the water adding device 30 and the air pipe 40 are all installed on the machine body 20. And, the water adding device 30 is to supply water to the water tank 11 of the steam generator 10 so that the steam generator 10 boils the water to generate steam. The air pipe 40 is communicated with the water container 11 of the steam generator 10 through one end thereof, and the air pipe 40 is communicated with the cooking cavity 21 of the machine body 20 through the other end thereof, so that the steam generated by the steam generator 10 is conveyed into the cooking cavity 21 of the machine body 20 through the air pipe 40.
With continued reference to fig. 4, in other embodiments of the present invention, a jet structure 22 is disposed on the body 20, and a plurality of jet holes are disposed on the jet structure 22. The injection structure 22 is connected to an end of the gas pipe 40 away from the steam generator 10, so that steam is uniformly injected to the surface of the food material in the cooking cavity 21 through the injection holes of the injection structure 22, and the food material is uniformly heated.
With continued reference to fig. 4, in other embodiments of the present invention, the water adding device 30 includes a water tank 31 and a water pump 32, and the water tank 31 is used for storing a large amount of water for the steam generator 10. The water pump 32 is used to pump the water in the water tank 31 into the water container 11 of the steam generator 10.
Preferably, an inlet of the water pump 32 is communicated with the water tank 31 through a water pipe, and an outlet of the water pump 32 is communicated with the water container 11 through a water pipe.
In addition, on the premise that the water pump 32 can pump water to the water container 11, a person skilled in the art may set the connection mode of the water pump 32, the water tank 31 and the water container 11 to any other feasible mode according to the requirement. For example, the water pump 32 is disposed in the water tank 31, and an outlet of the water pump 32 is communicated with the water container 11 through a water pipe.
In other embodiments of the present invention, one skilled in the art can omit the water tank 31 and connect the inlet of the water pump 32 to the external water source of the cooking device, such as a faucet, as needed.
Further, although not shown in the drawings, in other embodiments of the present invention, the liquid level meter 13 of the steam generator 10 includes a first temperature sensor 131 and a second temperature sensor 132, and the height of the first temperature sensor 131 is greater than the height of the second temperature sensor 132. In other words, in other embodiments of the present invention, the cooking apparatus employs the steam generator 10 described in some or further embodiments.
Alternatively, one skilled in the art may use any other possible steam generator 10 for cooking devices according to other embodiments of the present invention, as desired. For example, the steam generator 10 has three, four or five temperature sensors, but only two of the plurality of temperature sensors need to be used so that the steam generator 10 can secure the cooking performance of the cooking appliance.
Alternatively, the steam generator 10 is mounted on the body 20 in an inclined posture to ensure that at least two temperature sensors on the steam generator 10 have different heights.
As shown in fig. 5, in other embodiments of the present invention, the cooking apparatus further includes a controller 50, and the controller 50 is connected to the heating device 12, the first temperature sensor 131 and the second temperature sensor 132, respectively.

The temperature value may be a specific temperature value, or may be a number, a voltage signal, or a current signal that is characteristic of the temperature value.
Based on the foregoing description, it can be understood by those skilled in the art that, in the present invention, by providing the first temperature sensor 131 and the second temperature sensor 132 on the water container 11 and making the height of the first temperature sensor 131 greater than the height of the second temperature sensor 132, when the first temperature value detected by the first temperature sensor 131 is greater than the second temperature value detected by the second temperature sensor 132, it means that the liquid level of the water in the water container 11 is reduced below the first temperature sensor 131 and located above the second temperature sensor 132, and the water container 11 is about to be dried. At this time, the water adding device 30 is controlled to fill the water tank 11, so that the water tank 11 is prevented from being burnt dry.
Further, by inclining the inner bottom surface of the water container 11, the precipitated scale is collected to the lowest end of the water container 11 along the inner bottom surface of the water container 11 while preventing the water container 11 from being dried.
Alternatively, a person skilled in the art may also provide a drain hole at the lowest end of the water container 11 as needed to drain the water in the water container 11 through the drain hole, thereby preventing scale from accumulating in the water container 11.
