[0030] The present application is based on the discovery and realization of the inventors on the following facts and problems:

[0031] In the related art, a cooking appliance such as a steamer has a slow steam filling speed when cooking, which results in a slow temperature rise of the cooking cavity and affects the cooking efficiency and cooking effect.

[0032] Specifically, in the related art, the steam of a steamer is sprayed into the cooking cavity through a nozzle at a certain speed. Since the steam is sprayed at a fast speed, the steam is mainly concentrated on the path in the extension direction of the nozzle, and it takes a long time to gradually fill other positions of the cooking cavity, resulting in a slow filling speed, a slow temperature rise of the cooking cavity, and affecting the cooking efficiency and cooking effect.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] The steam inlet structure 1 according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0037] As shown in the drawings, the steam inlet structure 1 according to the embodiment of the present application comprises a box body 10 and a steam distribution plate 20. Figures 1-4

[0038] The box body 10 is provided with a steam inlet hole 11. The steam distribution plate 20 is provided with a plurality of steam distribution holes 21 arranged at intervals, and the steam distribution plate 20 separates the box body 10 into a steam inlet cavity 13 and a cooking cavity 12. The steam distribution plate 20 is provided with steam inlet grooves 22, which are respectively communicated with the steam inlet cavity 13 and the steam inlet hole 11.

[0039] Specifically, after the steam enters through the steam inlet hole 11, it flows under the guidance of the steam inlet grooves 22, and at the same time, the steam gradually enters the steam inlet cavity 13 above the steam distribution plate 20 in the process of flowing in the steam inlet grooves 22, and finally enters the cooking cavity 12 through the steam distribution holes 21 on the steam distribution plate 20.

[0040] According to the steam inlet structure 1 of the embodiment of the present application, by providing the steam distribution plate 20, the space in the box body 10 can be separated into the steam inlet cavity 13 and the cooking cavity 12 by the steam distribution plate 20. In this way, after the steam enters through the steam inlet hole 11, it can first be dispersed in the steam inlet cavity 13 and then enter the cooking cavity 12 through the plurality of steam distribution holes 21, so that the steam is evenly dispersed into the cooking cavity 12, avoiding excessive concentration of the steam, so that the steam forms an overall steam layer, and the air is squeezed out without mixing with the air, facilitating the steam to quickly fill the cooking cavity 12, improving the filling efficiency of the steam, thereby improving the steam inlet efficiency of the steam inlet structure 1 and the heating speed of the cooking cavity 12.

[0041] Furthermore, by providing the steam inlet grooves 22 on the steam distribution plate 20, the steam inlet grooves 22 are respectively communicated with the steam inlet cavity 13 and the steam inlet hole 11, so that the steam inlet grooves 22 can be used to guide the steam, which is helpful for the steam to diffuse in the extension direction of the steam inlet grooves 22. In this way, the steam can be more evenly dispersed into the steam inlet cavity 13, thereby further facilitating the steam to quickly fill the cooking cavity 12, improving the filling efficiency of the steam, improving the steam inlet efficiency of the steam inlet structure 1, and improving the heating speed of the cooking cavity 12.

[0042] ​Therefore, the steam inlet structure 1 has the advantages of high steam inlet efficiency and fast filling speed.

[0043] The steam inlet structure 1 according to the embodiments of the present application is described below with reference to the accompanying drawings.

[0044] In some embodiments of the present application, as shown in Figures 1-4 The steam inlet structure 1 according to the embodiments of the present application comprises a box body 10 and a steam distribution plate 20.

[0045] Specifically, as shown in Figures 1-4 The upper surface of the steam inlet groove 22 is open to communicate with the steam inlet cavity 13 (the up-down direction is shown by the arrow in the figure and is only for the convenience of description, and is not a limitation on the actual arrangement direction). In this way, the steam inlet groove 22 can be conveniently communicated with the steam inlet cavity 13, and the steam can enter the steam inlet cavity 13 more smoothly and uniformly from the steam inlet groove 22.

[0046] More specifically, as shown in Figures 1-4 The steam inlet hole 11 is communicated with at least one end of the steam inlet groove 22. In this way, the steam inlet groove 22 can be conveniently communicated with the steam inlet hole 11, and the steam can enter the steam inlet groove 22 more smoothly.

[0047] Advantageously, as shown in Figures 1-4 The steam inlet groove 22 is arranged at one side edge of the steam distribution plate 20. In this way, the steam inlet groove 22 can be conveniently arranged.

[0048] More advantageously, the diameter of the steam distribution hole 21 gradually increases from the position close to the steam inlet groove 22 to the position far away from the steam inlet groove 22. Since the speed of the steam gradually decreases with the increase of the flow distance after entering the steam inlet cavity 13 through the steam inlet groove 22, by reasonably arranging the diameter of the steam distribution hole 21, the steam can enter the cooking cavity 12 more uniformly and dispersedly, and the steam filling efficiency of the cooking cavity 12 is further improved.

[0049] Further, in the direction from the position close to the steam inlet groove 22 to the position far away from the steam inlet groove 22, the distance between every two adjacent steam distribution holes 21 gradually decreases. Since the speed of the steam gradually decreases with the increase of the flow distance after entering the steam inlet cavity 13 through the steam inlet groove 22, by reasonably arranging the distance between the steam distribution holes 21, the steam can enter the cooking cavity 12 more uniformly and dispersedly, and the steam filling efficiency of the cooking cavity 12 is further improved.

[0050] Optionally, in the length direction of the steam inlet groove 22, the diameter of the steam distribution hole 21 gradually increases from the position close to the steam inlet hole 11 to the position far away from the steam inlet hole 11. Since the speed of the steam gradually decreases with the increase of the flow distance after entering the steam inlet groove 22 through the steam inlet hole 11, by reasonably arranging the diameter of the steam distribution hole 21, the steam can enter the cooking cavity 12 more uniformly and dispersedly, and the steam filling efficiency of the cooking cavity 12 is further improved.

[0051] Further, the distance between every two adjacent steam holes 21 gradually decreases from the direction close to the steam inlet hole 11 to the direction far from the steam inlet hole 11 in the length direction of the steam inlet groove 22. Since the speed of the steam gradually decreases with the increase of the flow distance after the steam enters the steam inlet groove 22 through the steam inlet hole 11, the steam can be more uniformly dispersed into the cooking cavity 12 by reasonably setting the aperture of the steam hole 21, and the steam filling efficiency of the cooking cavity 12 is further improved.

[0052] Figures 1-4 A steam inlet structure 1 according to one specific example of the present application is shown. As shown, the steam inlet groove 22 is formed at the front edge of the steam distribution plate 20 (the front-rear direction is shown by the arrow in the figure and is only for the convenience of description, and is not a limitation on the actual setting direction). Figures 1-4 Thus, the steam inlet groove 22 can be conveniently set.

[0053] Specifically, as shown, the steam inlet groove 22 is formed by concave under the steam distribution plate 20. In this way, the formation of the steam inlet groove 22 can be facilitated, the number of parts can be reduced, and the assembly process can be simplified. Figure 2 Optionally, as shown, the steam inlet hole 11 is formed on the side wall of the box body 10. In this way, the steam inlet hole 11 can be conveniently set, and the steam inlet hole 11 can be conveniently connected to the steam source.

[0054] Figures 1-4 Advantageously, as shown, the steam inlet hole 11 communicates with one end of the steam inlet groove 22 and faces the other end. In this way, the flow of the steam in the steam inlet groove 22 can be smoother.

[0055] More specifically, as shown, the steam inlet groove 22 is a square groove. In this way, the steam inlet groove 22 can be adapted to the structure of the box body 10, and the steam inlet groove 22 can be conveniently set. Figures 1-4 The steam inlet cavity 13 is located above the cooking cavity 12. In this way, after the steam is discharged from the steam hole 21, the steam can gradually fill the cooking cavity 12 downward by sedimentation, thereby facilitating the improvement of the steam filling efficiency of the cooking cavity 12.

[0056] Figures 1-4 Specifically, the steam inlet hole can communicate with the steam source. The steam source can be provided by a heating device.

[0057] A heating device according to an embodiment of the present application is described below.

[0058] The heating device according to the embodiment of the present application comprises a water tank, an electrode, an electrical conductivity detection device, and a controller.

[0059] A heating device according to an embodiment of the present application is described below.

[0060] The heating device according to the embodiment of the present application comprises a water tank, an electrode, an electrical conductivity detection device, and a controller.

[0061] ​​The electrodes are used to heat water in the water tank. The conductivity detection device detects the conductivity of the water in the water tank. The controller is electrically connected with the electrodes and the conductivity detection device respectively to adjust the voltage of the electrodes according to the conductivity.

[0062] The heating device according to the embodiment of the present application can heat the water in the water tank by the electrodes, and the water itself is heated as a resistance medium, which can reduce the accumulation of scale, avoid affecting the heating efficiency of the heating device, and avoid the plugging or even burning of the heating device.

[0063] In addition, the conductivity of the water as a resistance medium is different due to different water quality, which results in different heating power of the water under the same voltage, and the heating power of the water is difficult to control. The conductivity detection device and the controller are arranged, and the controller is used to adjust the voltage of the electrodes according to the conductivity, which can facilitate the control of the heating power and avoid affecting the heating effect due to the excessive or insufficient heating power.

[0064] Therefore, the heating device according to the embodiment of the present application has the advantages of not easy to accumulate scale, high heating efficiency, and good heating effect.

[0065] Specifically, the electrodes are two and are arranged at intervals. In this way, the water between the two electrodes can be used as a resistance medium, and the water between the two electrodes can be directly heated by electrifying the water between the two electrodes, thereby avoiding the accumulation of scale.

[0066] Optionally, the two electrodes are arranged at intervals along the horizontal direction. In this way, the arrangement of the electrodes can be facilitated, and the two electrodes can be simultaneously immersed in or out of the water when the water level changes.

[0067] Specifically, when the water level in the water tank drops below the electrodes, the two electrodes are no longer conducted by the water, and the electrical connection of the two electrodes is naturally disconnected, thereby avoiding dry burning. Therefore, not only can dry burning be avoided to ensure the reliability of the heating device, but also the protection device can be omitted to reduce the cost.

[0068] More specifically, the electrodes are installed in the water tank through the mounting seat. In this way, the electrodes can be installed in the water tank, and the orientation and positioning of the electrodes can be facilitated.

[0069] In one specific embodiment, the mounting seat is located on the bottom wall of the water tank, and the electrodes are oriented along the vertical direction. In this way, the electrical connection between the electrodes can be disconnected when the water level is lowered to the vicinity of the bottom wall, thereby facilitating the control of the volume of the water tank.

[0070] In another specific embodiment, the mounting seat is located on the side wall of the water tank and adjacent to the bottom wall, and the electrodes are oriented along the horizontal direction. In this way, the electrical connection between the electrodes can be disconnected when the water level is lowered to the vicinity of the bottom wall, thereby facilitating the control of the volume of the water tank.

[0071] Specifically, the heating device further comprises a frequency converter, and the controller is electrically connected with the electrode through the frequency converter. Thus, the voltage of the electrode can be adjusted by the frequency converter, and the control of the voltage of the electrode is facilitated.

[0072] Optionally, the conductivity detection device comprises a TDS detection device. Thus, the conductivity of the water body can be fed back according to the TDS detection device, and the voltage of the electrode can be calculated according to the required power.

[0073] More specifically, the controller adjusts the voltage of the electrode according to the detection value of the TDS detection device, so that the voltage of the electrode is proportional to the detection value. It should be understood here that the voltage of the electrode is proportional to the detection value without considering the target power. In other words, the voltage of the electrode needs to be proportional to the detection value when the target power is constant. In this way, the heating power of the heating device can be controlled, and the influence of the heating effect caused by the excessively high or low heating power can be avoided.

[0074] The water tank is provided with a steam outlet. In this way, the steam generated by the water heated by the electrode can be discharged through the steam outlet, and the steam discharged from the steam outlet can be further introduced into the cooking cavity of the cooking appliance, so that the steam cooking of food can be realized.

[0075] Advantageously, the steam outlet is located at the upper portion of the water tank. In this way, the maximum water storage capacity of the water tank can be controlled, the volume of the water tank can be controlled, and the discharge of the steam can be facilitated.

[0076] In one embodiment, the steam outlet can be formed on the top wall of the water tank.

[0077] In another embodiment, the steam outlet can be formed on the side wall of the water tank and adjacent to the top wall.

[0078] Optionally, the electrode is a graphite electrode. In this way, not only can the accumulation of scale on the electrode be reduced, but also the cost can be reduced.

[0079] Specifically, the electrode is plate-shaped or columnar. In this way, the water body can be heated.

[0080] The working process of the heating device according to the embodiment of the present application is described below.

[0081] When the water storage in the water tank is insufficient, the two electrodes are in an open circuit, and the heating device is in an automatic off state, and no steam is generated.

[0082] When water is added to the water tank to make the electrodes conductive, the heating device is in a conductive state, and the graphite electrode utilizes the resistance of the water body in the water tank itself, and the water body itself acts as a resistance medium to heat the water body to generate steam.

[0083] Meanwhile, the TDS detection device detects the detection value of the TDS of the water and feeds back to the controller, the controller calculates the conductivity according to the TDS value, reflects the resistivity of the water body, and calculates the voltage value according to the target power value, and feeds back to the frequency converter to adjust the output voltage. Realize that under different water hardness conditions, the heating body can also adjust the power.

[0084] Specifically, the cooking cavity can be further connected with a steam inlet device and a steam extraction device. The steam inlet device can be in communication with the heating device or formed by the heating device.

[0085] The steam extraction device and the steam inlet device operate simultaneously for at least a period of time.

[0086] According to the steam path system of the embodiment of the present application, by arranging the steam extraction device, the air in the cooking cavity can be extracted to avoid the influence of the remaining air on the steam inlet speed, thereby improving the steam inlet efficiency of the steam path system.

[0087] Specifically, when used for a steam cooking appliance, the steam filling rate of the cooking cavity can be improved, and the cooking efficiency and cooking effect can be improved.

[0088] Furthermore, by simultaneously operating the steam extraction device and the steam inlet device for at least a period of time, in other words, simultaneously extracting steam and inletting steam for at least a period of time, compared with the prior art of first extracting steam and then inletting steam, the user's waiting time for steam extraction can be reduced, the total time required for steam inletting can be shortened, and the steam inletting efficiency can be improved.

[0089] Specifically, when used for a steam cooking appliance, the total time required for steam filling can be shortened, the user's waiting time can be reduced, and the cooking efficiency can be improved.

[0090] Therefore, the steam path system according to the embodiment of the present application has the advantages of fast steam inletting speed and high steam inletting efficiency.

[0091] Specifically, the cooking cavity has a steam extraction hole and a steam inlet hole, the steam extraction device is in communication with the cooking cavity through the steam extraction hole, and the steam inlet device is in communication with the cooking cavity through the steam inlet hole. In this way, the steam inlet device and the steam extraction device can be conveniently communicated with the cooking cavity of the box body.

[0092] Advantageously, the steam inlet hole is arranged at the upper part of the box body, and the steam extraction hole is arranged at the lower part of the box body. In this way, the steam inlet hole can be away from the steam extraction hole, and the steam extraction device can avoid extracting the steam just entering the cooking cavity, thereby avoiding affecting the steam inlet efficiency.

[0093] More advantageously, one of the steam inlet hole and the steam extraction hole is arranged at the side wall of the cooking cavity, and the other is arranged at the rear wall of the cooking cavity. In this way, the steam inlet hole can be away from the steam extraction hole, and the steam extraction device can avoid extracting the steam just entering the cooking cavity, thereby avoiding affecting the steam inlet efficiency.

[0094] Specifically, the air extraction device extracts air from the cooking cavity during at least a portion of the time when the cooking cavity is cooking food. This can improve the steam inlet efficiency of the steam path system during the cooking stage, thereby improving the cooking efficiency.

[0095] In one embodiment of the present application, the steam path system further comprises a temperature detection device for detecting the temperature in the cooking cavity, and the temperature detection device is in communication with the air extraction device. This can control the start and stop timing of the air extraction device according to the temperature in the cooking cavity.

[0096] Specifically, the air extraction device stops running when the detection value of the temperature detection device is greater than or equal to a predetermined value. This can stop the air extraction when the temperature in the cooking cavity reaches the required temperature, avoiding affecting the subsequent cooking effect.

[0097] In another embodiment of the present application, the steam path system further comprises a timing device, which stops the air extraction device after a predetermined time of operation of the air extraction device. This can control the stop timing of the air extraction device by timing, avoiding affecting the subsequent cooking effect.

[0098] Specifically, the steam path system further comprises a controller, which is in communication with the steam inlet device and the air extraction device respectively. This can facilitate the control of the operation timing of the steam inlet device and the air extraction device.

[0099] More specifically, the controller controls the steam inlet device and the air extraction device to run simultaneously when starting cooking. In other words, after the cooking appliance receives a cooking instruction, the steam inlet device and the air extraction device run simultaneously, the cooking cavity simultaneously inlets steam and extracts air, thereby improving the steam inlet efficiency of the steam path system.

[0100] Optionally, the air extraction device is a one-way air pump. This can facilitate the air extraction from the cooking cavity.

[0101] The working process of the steam path system according to the embodiment of the present application is described below.

[0102] After the cooking appliance receives a cooking instruction, the steam inlet device and the air extraction device run simultaneously, the cooking cavity simultaneously inlets steam and extracts air, the steam gradually fills the cooking cavity, the temperature in the cooking cavity gradually rises with the filling of the steam, the temperature detection device detects the temperature in the cooking cavity in real time, and when the temperature reaches a predetermined value, it indicates that the steam in the cooking cavity is filled to the required degree, and the air extraction device stops running, avoiding affecting the subsequent cooking process.

[0103] The control method of the cooking appliance according to the embodiment of the present application is described below, comprising the following steps:

[0104] When starting cooking, steam is introduced into the cooking cavity of the cooking appliance, and air is extracted from the cooking cavity.

[0105] The air suction is stopped when the temperature of the cooking cavity is greater than or equal to a predetermined temperature.

[0106] The cooking appliance according to the embodiment of the present application has the advantages of fast steam inlet speed and high steam inlet efficiency.

[0107] The control method of the cooking appliance according to the embodiment of the present application is described below and includes the following steps:

[0108] When the cooking is started, steam is supplied to the cooking cavity of the cooking appliance, and the cooking cavity is subjected to air suction.

[0109] The air suction is stopped after a predetermined time.
