Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a steam oven and a steam oven control method. Background Art

[0002] In recent years, with the gradual improvement of living standards, people's pursuit of quality of life has become higher and higher, so various kitchen appliances have also developed vigorously, and steam oven is one of these many kitchen appliances.

[0003] In the prior art, the application of steam ovens is very common, which provides great convenience for people's cooking. However, the steam ovens in the prior art all use saturated steam to heat food, and cannot adjust the humidity of the steam, which greatly limits the use of the steam ovens.

[0004] Therefore, it is very necessary to design a new steam furnace to solve the above problems. Summary of the invention

[0005] The first object of the present invention is to provide a steam oven to alleviate the technical problem that the steam oven in the prior art uses saturated steam to heat food and cannot adjust the humidity of the steam.

[0006] The steam furnace provided by the present invention comprises a furnace body, a steam generator and a steam heater, wherein the steam generator and the steam heater are fluidically connected, and the steam generator and the steam heater are respectively electrically connected to the control system of the furnace body; the steam generated by the steam generator enters the inner container of the furnace body after passing through the steam heater, and the steam heater can heat the steam flowing therethrough into superheated steam;

[0007] A humidity sensor is provided in the inner tank, and the humidity sensor is electrically connected to the control system, and is used to detect the humidity parameter in the inner tank and send the humidity parameter to the control system;

[0008] The control system is used to receive the humidity parameter. When the humidity parameter exceeds a specified value, the control system controls the steam heater to heat the steam flowing therethrough.

[0009] Furthermore, the steam generator and the steam heater are integrated in the same shell, and an exhaust pipe is connected to the shell; one end of the exhaust pipe is connected to the exhaust port of the steam heater, and the other end is connected to the inner tank.

[0010] Furthermore, the steam heater is arranged above the steam generator, and the exhaust pipe is arranged at the top of the shell.

[0011] Furthermore, an air inlet is provided on the inner tank, and the exhaust pipe is connected to the air inlet.

[0012] Furthermore, the shell is arranged in the furnace body and located behind the inner container.

[0013] Furthermore, the humidity sensor is arranged at the rear end of the inner container.

[0014] Furthermore, a temperature sensor is provided in the inner tank, and the temperature sensor is electrically connected to the control system, and is used to detect the temperature parameters in the inner tank and send the temperature parameters to the control system;

[0015] The control system is used to receive the temperature parameter. When the temperature parameter exceeds a specified value, the control system controls the steam generator to stop working. When the temperature parameter is lower than the specified value, the control system controls the steam generator to start.

[0016] Furthermore, the temperature sensor is arranged at the rear end of the inner tank.

[0017] Further, it includes an exhaust system, the exhaust system is electrically connected to the control system; the top of the inner tank is provided with an exhaust hole, the exhaust hole is fluidically connected to the exhaust system;

[0018] When the humidity sensor detects that the humidity parameter exceeds a specified value, the control system controls the exhaust system to start.

[0019] Furthermore, the steam oven also includes an ultrasonic oscillator electrically connected to the control system, wherein the ultrasonic oscillator is arranged in the oven body and located outside the inner pot; when the humidity sensor detects that the humidity parameter in the inner pot is lower than a specified value, the control system controls the ultrasonic oscillator to start and provide water mist into the inner pot.

[0020] The steam oven provided by the present invention has the following beneficial effects compared with the prior art:

[0021] The steam furnace provided by the present invention comprises a furnace body, a steam generator and a steam heater, the steam generator and the steam heater are fluidically connected, and the steam generator and the steam heater are respectively electrically connected to the control system of the furnace body; the steam generated by the steam generator enters the inner tank of the furnace body after passing through the steam heater, and the steam heater can heat the steam flowing therethrough into superheated steam; a humidity sensor is arranged in the inner tank, and the humidity sensor is electrically connected to the control system, and is used to detect the humidity parameter in the inner tank and send the humidity parameter to the control system; the control system is used to receive the humidity parameter, and when the humidity parameter exceeds a specified value, the control system controls the steam heater to heat the steam flowing therethrough.

[0022] When the steam oven provided by the present invention is used to steam food, the steam generator provides steam to the inner pot, the humidity sensor detects the humidity data in the inner pot, and sends the humidity parameter to the control system. If the humidity sensor detects that the humidity in the inner pot exceeds the specified value, the control system controls the steam heater to start working, so that the steam heater performs secondary heating on the steam generated by the steam generator, heats the steam generated by the steam generator into superheated steam, and passes the superheated steam into the inner pot. On the one hand, the superheated steam has a high temperature and is dry, and can exchange heat with the water and saturated steam in the inner pot, increase the temperature of the steam, make it reach a superheated state, and become dry steam, thereby reducing the humidity in the inner pot; on the other hand, a large amount of superheated steam enters the inner pot, which can increase the pressure in the inner pot, so that part of the wet steam can be discharged from the inner pot from the exhaust port, which is also conducive to reducing the humidity in the inner pot. On the contrary, if the humidity sensor detects that the humidity in the inner pot is lower than the specified value, the control system controls the steam heater to stop working, so that the steam generated by the steam generator directly enters the inner pot, thereby increasing the humidity in the inner pot.

[0023] In summary, it can be seen that the steam oven provided by the present invention can adjust the humidity in the inner pot during operation, which can significantly improve the problem that the steam oven in the prior art uses saturated steam to heat food and cannot adjust the humidity of the steam, thereby extending the use range of the steam oven.

[0024] In addition, the steam oven provided by the present invention can also use superheated steam to bake food. When using the steam oven provided by the present invention to bake food, the steam oven can increase or reduce the humidity according to the cooking requirements of the food. For example, when the humidity sensor detects that the humidity in the inner pot is lower than the specified value, the control system controls the steam heater to stop working, so that the steam generated by the steam generator directly enters the inner pot, thereby increasing the humidity in the inner pot; when the humidity sensor detects that the humidity in the inner pot is higher than the specified value, the control system controls the steam heater to start, and superheated steam is passed into the inner pot, thereby reducing the humidity in the inner pot. By controlling the humidity in the inner pot, the effect of baking food can be better. When using the steam oven provided by the utility model to keep food warm, the working time of the steam heater can be adjusted so that the steam oven can provide different humidity according to the characteristics of the food (for example: drying and keeping fried food warm).

[0025] The second object of the present invention is to provide a steam oven control method to alleviate the technical problem in the prior art that the steam oven uses saturated steam to heat food and cannot adjust the humidity of the steam.

[0026] The steam furnace control method provided by the present invention is applied to the steam furnace described above, and the method comprises:

[0027] The steam generated by the steam generator enters the inner container of the furnace body after passing through the steam heater, and the steam heater heats the steam flowing therethrough into superheated steam;

[0028] The humidity sensor provided in the inner tank detects the humidity parameter in the inner tank and sends the humidity parameter to the control system;

[0029] The control system receives the humidity parameter, and when the humidity parameter exceeds a specified value, the control system controls the steam heater to heat the steam flowing therethrough.

[0030] Furthermore, a temperature sensor is provided in the inner tank, and the temperature sensor is electrically connected to the control system; the method further comprises:

[0031] The temperature sensor detects the temperature parameters in the inner tank and sends the temperature parameters to the control system;

[0032] The control system receives the temperature parameter. When the temperature parameter exceeds a specified value, the control system controls the steam generator to stop working. When the temperature parameter is lower than the specified value, the control system controls the steam generator to start.

[0033] Furthermore, the control system receives the humidity parameter, and when the humidity parameter is lower than a preset value, the control system controls the steam generator to operate to generate saturated steam and controls the steam heater to stop heating the steam flowing therethrough.

[0034] The steam oven control method provided by the present invention is applied to the steam oven described above, and can enable the steam oven to achieve the above beneficial effects, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figure 1 As shown, the steam furnace provided in this embodiment includes a furnace body 1, a steam generator and a steam heater, the steam generator and the steam heater are fluidically connected, and the steam generator and the steam heater are respectively electrically connected to the control system of the furnace body 1. The steam generated by the steam generator enters the inner tank 2 of the furnace body 1 after passing through the steam heater, and the steam heater can heat the steam flowing therethrough into superheated steam.

[0043] A humidity sensor 3 is provided in the inner tank 2. The humidity sensor 3 is electrically connected to the control system and is used to detect humidity parameters in the inner tank 2 and send the humidity parameters to the control system.

[0044] The control system is used to receive a humidity parameter. When the humidity parameter exceeds a specified value, the control system controls the steam heater to heat the steam flowing therethrough.

[0045] When the steam oven provided in this embodiment is used to steam food, the steam generator provides steam to the inner pot 2, and the humidity sensor 3 detects the humidity data in the inner pot 2 and sends the humidity parameter to the control system. If the humidity sensor 3 detects that the humidity in the inner pot 2 exceeds the specified value, the control system controls the steam heater to start working, so that the steam heater performs secondary heating on the steam generated by the steam generator, heats the steam generated by the steam generator into superheated steam, and passes the superheated steam into the inner pot 2. On the one hand, the superheated steam has a high temperature and is dry, and can exchange heat with the water and saturated steam in the inner pot 2, increase the temperature of the steam, make it reach a superheated state, and become dry steam, thereby reducing the humidity in the inner pot 2; on the other hand, a large amount of superheated steam enters the inner pot 2, which can increase the pressure in the inner pot 2, so that part of the wet steam can be discharged from the inner pot 2 from the exhaust port, which is also conducive to reducing the humidity in the inner pot 2. On the contrary, if the humidity sensor 3 detects that the humidity in the inner pot 2 is lower than the specified value, the control system controls the steam heater to stop working, so that the steam generated by the steam generator directly enters the inner pot 2, thereby increasing the humidity in the inner pot 2.

[0046] In summary, the steam oven provided in this embodiment can adjust the humidity in the inner pot 2 during operation, which can significantly improve the problem that the steam oven in the prior art uses saturated steam to heat food and cannot adjust the humidity of the steam, thereby making the steam oven more widely used.

[0047] In addition, the steam oven provided in this embodiment can also use superheated steam to bake food. When using the steam oven provided in this embodiment to bake food, if the humidity sensor 3 detects that the humidity in the inner pot 2 is lower than the specified value, the control system controls the steam heater to stop working, so that the steam generated by the steam generator directly enters the inner pot 2, thereby increasing the humidity in the inner pot 2; if the humidity sensor 3 detects that the humidity in the inner pot 2 is higher than the specified value, the control system controls the steam heater to start, and superheated steam is passed into the inner pot 2, thereby reducing the humidity in the inner pot 2. By controlling the humidity in the inner pot, the effect of baking food can be better. When using the steam oven provided in this embodiment to keep food warm, the type of food is set through the product control system. The control system can adjust the working time of the steam heater according to the type of food, so that the steam oven can provide different humidity according to the characteristics of the food, such as: drying and keeping fried food warm.

[0048] In this embodiment, the structures of the steam generator and the steam heater may be the same or different.

[0049] As a specific implementation method, the structures of the steam generator and the steam heater can be the same, and both can adopt the steam generator in the prior art.

[0050] In this embodiment, the control system may include a control chip, and the control chip has a control function.

[0051] It should be noted that when the humidity parameter exceeds a specified value, the control system controls the steam heater to heat the steam flowing therethrough, and the specified value may be specifically set according to different foods.

[0052] The steam generator and the steam heater are fluidically connected. The fluid connection mentioned here means that the fluid can flow and be transmitted between the steam generator and the steam heater. For example, a pipeline may be provided between the exhaust port of the steam generator and the air inlet of the steam heater.

[0053] The steam heater is able to heat the steam flowing through it into superheated steam. Obviously, the steam heater will only work when the steam generator is working.

[0054] In the optional technical solution of this embodiment, the steam generator and the steam heater can be integrated in the same shell 4, wherein the upper half of the shell 4 is the steam heating part, and the lower half is the steam generator, the upper half and the lower half are connected in gas path, and an exhaust pipe 5 is provided on the shell 4. One end of the exhaust pipe 5 is connected to the exhaust port of the steam heater, and the other end is connected to the inner pot 2.

[0055] Integrating the steam generator and the steam heater in the same housing 4 makes the assembly and maintenance of the steam oven easier.

[0056] In an optional technical solution of this embodiment, the steam heater can be arranged above the steam generator, and the exhaust pipe 5 is arranged at the top of the shell 4.

[0057] In an optional technical solution of this embodiment, an air inlet may be provided on the inner liner 2, and the exhaust pipe 5 is connected to the air inlet.

[0058] As an alternative, a plurality of air inlets may be arranged at intervals on the inner liner 2 , and the plurality of air inlets are all connected to the exhaust pipe 5 .

[0059] In an optional technical solution of this embodiment, the shell 4 (including the steam generator and the steam heater inside the shell 4 ) can be arranged in the furnace body 1 and located behind the inner pot 2 .

[0060] As an alternative, the shell 4 can also be arranged in the furnace body 1 and located above the inner pot 2, or located on the side of the inner pot 2.

[0061] In an optional technical solution of this embodiment, the humidity sensor 3 can be arranged at the rear end of the inner container 2 .

[0062] Obviously, the humidity sensor 3 can be set at the rear end of the inner liner 2, but is not limited to being set at the rear end of the inner liner 2, and can also be set at other positions in the inner liner 2, as long as it can detect the humidity data in the inner liner 2.

[0063] In an optional technical solution of this embodiment, a temperature sensor 6 may be provided in the inner tank 2. The temperature sensor 6 is electrically connected to the control system for detecting temperature parameters in the inner tank 2 and sending the temperature parameters to the control system.

[0064] The control system is used to receive temperature parameters. When the temperature parameter exceeds a specified value, the control system controls the steam generator to stop working. When the temperature parameter is lower than the specified value, the control system controls the steam generator to start.

[0065] A temperature sensor 6 is provided in the inner pot 2. The temperature in the inner pot 2 is detected by the temperature sensor 6, and the temperature parameters are sent to the control system, so that the control system can timely control the steam generator to turn on or off, thereby preventing the temperature in the inner pot 2 from exceeding the maximum temperature suitable for cooking food or being lower than the minimum temperature suitable for cooking food, which affects the taste of the food.

[0066] The steam heater is used to reheat the steam generated by the steam generator, so obviously, when the steam generator stops working, the steam heater also stops working; conversely, when the steam generator starts working, the steam heater does not necessarily start working.

[0067] It should be noted that the critical value of the temperature parameter in the inner pot 2 can be set specifically according to the specific food.

[0068] In an optional technical solution of this embodiment, the temperature sensor 6 can be arranged at the rear end of the inner tank 2.

[0069] Obviously, the temperature sensor 6 can be set at the rear end of the inner tank 2, but is not limited to being set at the rear end of the inner tank 2, and can also be set at other positions in the inner tank 2, as long as the temperature data in the inner tank 2 can be detected.

[0070] In an optional technical solution of this embodiment, the steam oven may include an exhaust system 7, which is electrically connected to the control system. An exhaust hole 21 is provided at the top of the inner pot 2, and the exhaust hole 21 is fluidically connected to the exhaust system 7. When the humidity sensor 3 detects that the humidity parameter exceeds a specified value, the control system controls the exhaust system 7 to start.

[0071] An exhaust hole 21 is set at the top of the inner liner 2, and the exhaust hole 21 is fluidly connected to the exhaust system 7. When the humidity parameter exceeds the specified value, the control system controls the exhaust system 7 to start, and the exhaust system 7 can force the moisture in the inner liner 2 to be discharged, which is conducive to quickly reducing the humidity in the inner liner 2.

[0072] In the optional technical solution of this embodiment, the steam oven may further include an ultrasonic oscillator electrically connected to the control system, which is arranged in the furnace body 1 and located outside the inner pot 2; when the humidity sensor 3 detects that the humidity parameter in the inner pot 2 is lower than a specified value, the control system controls the ultrasonic oscillator to start and provide water mist into the inner pot 2.

[0073] An ultrasonic oscillator is arranged outside the inner liner 2 to provide water mist into the inner liner 2. When the humidity sensor 3 detects that the humidity parameter in the inner liner 2 is lower than a specified value, the control system controls the ultrasonic oscillator to start and provide water mist into the inner liner 2, thereby quickly increasing the humidity in the inner liner 2.

[0074] The cooking process of the steam oven can be: the steam generator and the steam heater work together to generate saturated steam or superheated steam, the generated gas enters the inner pot 2 through the exhaust pipe 5 to heat the food, the temperature sensor 6 detects the temperature in the inner pot 2 in real time, and the humidity sensor 3 detects the humidity in the inner pot 2 in real time. The control system controls whether the steam heater works according to the set food cooking temperature and humidity requirements combined with the real-time data feedback from the humidity sensor 3 and the temperature sensor 6, to adjust the temperature and humidity in the inner pot.

[0075] On the basis of the above embodiment, this embodiment further provides a steam furnace control method. Specifically, the method is applied to the steam furnace provided in the above embodiment. Specifically, the steam furnace comprises a furnace body 1, a steam generator and a steam heater. The steam generator and the steam heater are fluidically connected, and the steam generator and the steam heater are electrically connected to the control system of the furnace body 1 respectively; Figure 2 A flow chart of a steam furnace control method is shown, the method comprising the following steps:

[0076] Step S202, the steam generated by the steam generator enters the inner pot 2 of the furnace body 1 after passing through the steam heater, and the steam heater heats the steam flowing therethrough into superheated steam;

[0077] Step S204, the humidity sensor 3 provided in the inner liner 2 detects the humidity parameter in the inner liner 2 and sends the humidity parameter to the control system;

[0078] Step S206: The control system receives the humidity parameter. When the humidity parameter exceeds a specified value, the control system controls the steam heater to heat the steam flowing therethrough.

[0079] In a specific implementation, a temperature sensor 6 is provided in the inner tank 2, and the temperature sensor 6 is electrically connected to the control system; the method further includes:

[0080] The temperature sensor 6 detects the temperature parameters in the inner container 2 and sends the temperature parameters to the control system;

[0081] The control system receives the temperature parameter, and when the temperature parameter exceeds the specified value, the control system controls the steam generator to stop working, and when the temperature parameter is lower than the specified value, the control system controls the steam generator to start. The specified value mentioned above can be a temperature value directly input by the user, or a set temperature value in each cooking time period according to the cooking program.

[0082] In a specific control method, the control system receives the humidity parameter. During grilling using superheated steam, when the humidity parameter is lower than a preset value, the control system controls the steam generator to generate saturated steam and controls the steam heater to stop heating the steam flowing therethrough.

[0083] The steam oven control method provided in this embodiment has the same technical features as the steam oven provided in the above embodiments, and therefore can solve the same technical problems and achieve the same technical effects.

[0084] Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the steam boiler control method described above can refer to the corresponding process in the aforementioned embodiment, and will not be repeated here.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
