Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a steam oven and a control method thereof. BACKGROUND

[0002] At present, with the continuous improvement of people's living standards, people's demand for healthy diet is getting higher and higher, and steam ovens with steam function are more and more popular and chosen by people.

[0003] The steam oven with steam function is internally provided with a steam system, which includes a water storage tank, a steam generator, a water inlet component and the like, and can generate steam for heating food. In the case that any component in the steam system is abnormal, the steam system cannot operate normally, which affects the cooking effect. SUMMARY

[0004] The present application provides a steam oven and a control method thereof, which can detect the abnormal state of the steam oven in time and accurately.

[0005] In order to achieve the above purpose, the present application adopts the following technical scheme.

[0006] In a first aspect, the present application provides a steam oven, which comprises: an inner container having a cooking cavity for placing food materials; a water storage tank for storing water; a steam generator in communication with the water storage tank through a water inlet pipeline and in communication with the cooking cavity through a steam outlet pipeline, for heating water from the water storage tank to boiling to continuously generate steam and output the steam to the cooking cavity through the steam outlet pipeline; a water inlet component arranged on the water inlet pipeline, for conveying water in the water storage tank to the steam generator; a flow detection component arranged on the water inlet pipeline, for generating a pulse signal based on the detected water inlet amount of the steam generator and counting the pulse signal; and a controller configured to: in the case that the steam oven operates in a steam mode, acquire the running time length of the water inlet component in a current working period; wherein the current working period comprises a water inlet phase and a heating phase, the water inlet component operates in the water inlet phase, and the steam generator operates in the heating phase; acquire the first pulse signal number through the flow detection component when the running time length reaches a first preset time length; and determine that the water storage tank is short of water in the case that the first pulse signal number is less than a first preset pulse signal number.

[0007] The technical scheme provided by the embodiments of the present application brings at least the following beneficial effects: in the case that the steam box is running in the steam mode, when the running time length of the water inlet component reaches the first preset time length, the number of first pulse signals is obtained by the flow detection component, and in the case that the number of first pulse signals is less than the first preset number of pulse signals, it is determined that the water storage tank is out of water.

[0013] In some embodiments, the controller is further configured to: acquire a second temperature of the steam generator by the temperature sensor before the water inlet component operates in the current working cycle; send a prompt information for prompting an abnormality of the controller when the second temperature is greater than or equal to a second preset temperature; and the second preset temperature is greater than or equal to the first preset temperature.

[0014] In the second aspect, the embodiments of the present application provide a control method of a steam box, the control method comprising: acquiring a running duration of a water inlet component in a current working cycle when the steam box operates in a steam mode; wherein the current working cycle comprises a water inlet phase and a heating phase, the water inlet component operates in the water inlet phase, and a steam generator operates in the heating phase; acquiring a first pulse signal number by a flow detection component when the running duration reaches a first preset duration; and determining that a water tank is out of water when the first pulse signal number is less than a first preset pulse signal number.

[0033] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0034] It should be noted that all directional indications, such as upper, lower, left, right, front, back, etc., are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.

[0035] The terms "first", "second", etc. are only used for description purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0036] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected. For a person of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. In addition, when describing the pipeline, the "connected" and "connected" used in the present application have the meaning of conducting. The specific meaning needs to be understood in combination with the context.

[0037] In the embodiments of the present application, the words such as "exemplary" or "for example" are used to represent an example, illustration or description. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the words such as "exemplary" or "for example" are intended to present the relevant concept in a specific manner.

[0038] The steam system of the steam oven is composed of a water storage tank, a steam generator, a water inlet component and the like. In the case of any abnormality in any one of the components, it is possible to directly cause the steam to be unable to be output, and further cause the steam mode of the steam oven to be unable to be normally used. In order to ensure that each component is normally operated, the traditional method is to increase a detection component on each component, such as a remaining water amount detection component of the water storage tank for detecting whether the water tank is out of water. However, this method makes the overall structure of the steam system more complex, the manufacturing cost is higher, and the error cannot be directly reported when the component is abnormal.

[0039] Based on this, the embodiment of the present application provides a control method of a steam oven. When the running time of the water inlet component reaches the first preset time length in the case that the steam oven runs in the steam mode, the first pulse signal number is obtained by the flow detection component, and in the case that the first pulse signal number is less than the first preset pulse signal number, it is determined that the water storage tank is out of water. In this way, the detection of the water storage tank out of water is performed according to the pulse signal number detected by the flow detection component, so that the abnormal state of the water storage tank out of water can be detected in time and accurately without adding additional detection components, and the poor experience of the user caused by the water storage tank out of water is avoided.

[0040] In the embodiment of the present application, the steam oven is a cooking device with a steam heating function. For example, the steam oven can be a steam oven, an integrated cooker with a steam heating function, etc., which is not limited.

As shown in the figure, the steam oven 100 includes a cabinet 10, an inner container 20 (not shown in the figure) and a door body 30. Figure 1 Figure 1 The cabinet 10 is used to protect the electrical components inside the steam oven 100, close the channel between the inside and the outside of the steam oven 100, and avoid damage to the electrical components.

[0042] In some embodiments, the cabinet 10 is approximately a cuboid as shown in the figure, or can be other shapes. Figure 1

[0043] In some embodiments, the inner container 20 is arranged in the cabinet 10, and the inner container 20 forms a cooking cavity with an opening inside, which can place food materials that need to be processed by the steam oven 100.

[0044] In some embodiments, the door body 30 is hinged to the cabinet 10 through a door hinge assembly, so that the door body 30 can close or open the access opening of the cooking cavity, thereby realizing the operation of taking out or putting in the food materials to be processed from the cooking cavity.

[0046] In some embodiments, the water storage tank 101 is horizontally arranged at the top outside of the cooking cavity, and is used to store water.​​​​

[0047] In some embodiments, one end of the water inlet pipeline 102 is in communication with the water storage tank 101, and the other end is in communication with an opening at the bottom of the steam generator 105. Thus, the water in the water storage tank 101 can enter the steam generator 105 through the water inlet pipeline 102.

[0048] In some embodiments, the water inlet component 103 is arranged on the water inlet pipeline 102, and is configured to draw the water in the water storage tank 101 into the steam generator 105.

[0049] In some embodiments, the flow detection component 104 is arranged on the water inlet pipeline 102, and is configured to generate a pulse signal based on the detected water inlet amount of the steam generator, and to process the pulse signal.

[0050] In some embodiments, the steam generator 105 is configured to heat the water from the water storage tank 101 to boiling to generate steam. The steam generator 105 can be a boiling water type steam generator, a boiler type steam generator, an atomization steam generator, etc.

[0051] Optionally, the steam generator 105 can be vertically arranged at the back of the cooking cavity.

[0052] In some embodiments, one end of the first steam outlet pipeline 106 is in communication with the steam generator 105, and the other end is in communication with the water-steam separator 108, and is configured to deliver the steam generated in the steam generator 105 to the water-steam separator 108.

[0053] In some embodiments, one end of the second steam outlet pipeline 107 is in communication with the water-steam separator 108, and the other end is in communication with the cooking cavity, and is configured to deliver the steam separated by the water-steam separator 108 to the cooking cavity.

[0054] In some embodiments, the water-steam separator 108 is configured to separate the steam from the steam generator 105 into gas and liquid, and to deliver the separated steam to the cooking cavity through the second steam outlet pipeline 107.

[0055] Optionally, the water-steam separator 108 can be vertically arranged at the back of the cooking cavity, and the top end of the water-steam separator 108 can be higher than the top end of the steam generator 105.

[0056] In some embodiments, the temperature sensor 109 is arranged on the surface of the steam generator 105, and is configured to detect the temperature of the steam generator 105.

[0057] In some embodiments, the temperature controller 110 is connected in series with a circuit of the steam generator 105, and is configured to cut off the circuit when the temperature of the steam generator 105 is greater than a third preset temperature, so that the steam generator 105 stops heating.

[0058] In some embodiments, the temperature limiter 111 is connected in series to another circuit of the steam generator 105, for cutting off the circuit when the temperature of the steam generator 105 is greater than a fourth preset temperature in case the temperature controller 110 fails, so as to stop the steam generator 105 from heating. The fourth preset temperature is greater than the third preset temperature.

[0059] In some embodiments, one end of the water drainage pipeline 112 is connected to the water storage tank 101, and the other end is connected to the steam generator 105. Thus, the water vapor separator 108 is connected to the water drainage pipeline 112 through the first steam outlet pipeline 106 and the steam generator 105.

[0060] In some embodiments, the water drainage component 113 is arranged on the water drainage pipeline 112, for transporting water in the steam generator 105 and the water vapor separator 108 to the water storage tank 101.

[0061] In some embodiments, the controller 114 is a device that can generate operation control signals according to instruction operation codes and timing signals, and instruct the steam tank 100 to execute control instructions. For example, the controller 114 can be a central processing unit (CPU), a general processor network processor (NP), a digital signal processing (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof. The controller 114 can also be other devices with processing functions, such as circuits, devices or software modules, and the embodiments of the present application do not make any limitation thereto.

[0062] The controller 114 is electrically connected to the water inlet component 103, the flow detection component 104, the steam generator 105, the temperature sensor 109, the temperature controller 110, the temperature limiter 111 and the water drainage component 113, for controlling the operation of each component electrically connected thereto, so as to realize the predetermined functions of the steam tank 100.

[0063] Figure 3 A hardware structure schematic diagram of a steam tank according to an exemplary embodiment of the present application is provided. As shown in Figure 3 The steam tank 100 further includes a back heating pipe 115, a bottom heating pipe 116, a display panel 117, an operation panel 118, a voice device 119 and a communicator 120.

[0064] In some embodiments, as shown in Figure 4 The back heating pipe 115 is arranged on the back of the inner side of the cavity, for heating the food materials in the cavity.

[0065] In some embodiments, as shown in FIG. 1, the bottom heating pipe 116 is arranged at the bottom of the inner side of the cavity for heating the food materials in the cavity. Figure 4

[0066] In some embodiments, the display panel 117 can be a liquid crystal display panel, an organic light-emitting diode (OLED) display panel. The specific type, size, resolution, and the like of the display panel are not limited. The display panel 117 can be used to display the control panel of the steamer 100, and the steamer 100 can feed back the current operation mode of the steamer 100 through the display panel 117. For example, the steamer 100 runs in a pure steaming mode, a high-temperature steaming mode, or a tender roasting mode, etc.

[0067] In some embodiments, the operation panel 118 has function keys. For example, the function keys include an on / off key, a mode selection key, a temperature selection key, a + (increase) key, a - (decrease) key, etc. In this way, the user can interact with the steamer 100 through the operation panel 118 to adjust the mode, temperature, etc. of the steamer 100.

[0068] In some embodiments, the voice device 119 is used to issue prompt information. For example, when the water storage tank is out of water, the voice device 119 issues prompt information for prompting that the water storage tank is out of water. For another example, when the steam generator 105 is abnormal, the voice device 119 issues prompt information for prompting that the steam generator 105 is abnormal. For another example, when the controller 114 is abnormal, the voice device 119 issues prompt information for prompting that the controller 114 is abnormal.

[0069] In some embodiments, the communicator 120 is a component for communicating with external devices or external servers according to various communication protocol types. For example, the communicator 120 can include at least one of a Wi-Fi chip, a Bluetooth communication protocol chip, a wired Ethernet communication protocol chip, other network communication protocol chips or near field communication protocol chips, and an infrared receiver. The communicator 120 can be used to communicate with other devices or communication networks (such as Ethernet, radio access network (RAN), wireless local area networks (WLAN), etc.).

[0070] ​In some embodiments, the controller 114 can communicate with a terminal device used by a user through the communicator 120. For example, after the steamer 100 completes a cooking program, the controller 114 can send a prompt message such as “food is cooked” to the terminal device used by the user through the communicator 120, prompting the user that the cooking program has been completed and the food can be taken out of the steamer 100.

[0071] In some embodiments, based on Figure 4 As shown in the steamer 100, when the steamer 100 is running in the steam mode, the controller 114 can obtain the running duration of the water inlet component 103 in the current working period, and when the running duration reaches the first preset duration, obtain the first pulse signal number through the flow detection component 104. Thus, when the first pulse signal number is less than the first preset pulse signal number, it is determined that the water storage tank 101 is out of water. Or, when the first pulse signal number is greater than or equal to the first preset pulse signal number, it is determined that the water storage tank 101 is not out of water, and the water inlet component 103 is controlled to continue running.

[0072] In some embodiments, when it is determined that the water storage tank 101 is out of water, the controller 114 can also issue a prompt message through the voice device 119 to prompt that the water storage tank 101 is out of water.

[0073] In some embodiments, before the controller 114 obtains the first pulse signal number through the flow detection component 104, the controller 114 also obtains the second pulse signal number through the flow detection component 104 when the running duration of the water inlet component 103 reaches the second preset duration, and when the second pulse signal number is greater than or equal to the second preset pulse signal number, it is determined that the water storage tank 101 is not out of water, and the water inlet component 103 is controlled to stop running. Or, when the second pulse signal number is less than the second preset pulse signal number, the water inlet component 103 is controlled to continue running.

[0074] In some embodiments, the controller 114 can also obtain the running mode and the set temperature of the steamer 100, so that according to the running mode and the set temperature, the target water inlet amount of the steam generator 105 in the current working period and the second preset duration corresponding to the target water inlet amount can be determined. The controller 114 also converts the target water inlet amount into the second preset pulse signal number according to the preset parameter of the flow detection component 104.

[0075] In some embodiments, the controller 114 can also obtain the continuous running duration of the steam generator 105; when the continuous running duration reaches the third preset duration, obtain the first temperature of the steam generator 105 through the temperature sensor 109, and when the first temperature is less than the first preset temperature, issue a prompt message through the voice device 119 to prompt that the steam generator is abnormal.

[0076] In some embodiments, the controller 114 can also obtain the second temperature of the steam generator 105 through the temperature sensor 109 before the water inlet component 103 operates in the current working period, and issue the prompt information for prompting the controller abnormality through the voice device 119 when the second temperature is greater than or equal to the second preset temperature.

[0077] Figure 5 Another hardware structure schematic diagram of the steam generator provided by the present application according to the exemplary embodiments is provided, which includes a water inlet component 201, a steam generator 202, a water-vapor separator 203, a temperature sensor 204, a temperature controller 205, a temperature limiter 206, a water outlet component 207, a back heating pipe 208, a bottom heating pipe 209, a display panel 210, an operation panel 211, a voice device 212, a communicator 213, and a controller 214.

[0078] In addition, the specific description of the steam generator 200 can refer to the specific description of the steam generator 100 shown in the above Figure 2 and Figure 3 , and details are not described herein.

[0079] In some embodiments, in the case that the steam generator 200 does not have the flow detection component 104, the controller 214 obtains the temperature A of the steam generator through the temperature sensor 204 when the steam generator 202 operates. After the water inlet component 201 operates, that is, after the water inlet component delivers the water in the water storage tank to the steam generator 202, the controller 214 obtains the temperature B of the steam generator through the temperature sensor 204. In the case that the temperature B is greater than or equal to the temperature A, it is determined that the water storage tank is out of water.

[0080] In addition, in a possible implementation, if Figure 2 the flow detection component 104 in the steam generator 100 shown in the above is damaged or in an abnormal state, and thus cannot detect the water inlet amount of the steam generator 105, the control method for detecting the water shortage of the water storage tank can adopt Figure 5 the control method for detecting the water shortage of the steam generator 200 shown in the above.

[0081] It can be understood that the structure shown in the embodiments of the present application does not constitute a specific limitation on the steam generator. In other embodiments of the present application, the steam generator can include more or fewer components than shown in the figure, or combine certain components, or split certain components, or different component arrangements. The components shown in the figure can be implemented in hardware, software, or a combination of software and hardware.

[0082] The specific schemes of the present application are described in detail below with reference to the accompanying drawings.

[0083] The present application provides a control method for a steam generator, as shown inFigure 6 The control method can include the following steps, as shown in the figure:

[0084] S101, the controller acquires the running duration of the water inlet component in the current working cycle when the steam oven is running in the steam mode.

[0085] The steam mode is a mode in which the steam generator needs to run to generate steam. The steam mode includes pure steaming mode, high-temperature steaming mode, tender roasting mode, etc. The current working cycle includes a water inlet stage and a heating stage. The water inlet component runs in the water inlet stage, and the steam generator runs in the heating stage.

[0086] It can be understood that, when the steam oven is running in the steam mode, the water inlet component and the steam generator are periodically operated. In each working cycle, the water inlet component is controlled to run for a first duration in the water inlet stage and then pause, and after the water inlet component pauses, the steam generator is controlled to run for a second duration in the heating stage.

[0087] In some embodiments, the user can select the running mode of the steam oven through the operation panel of the steam oven, and the controller controls the operation of various components of the steam oven based on the running mode selected by the user. For example, the running mode selected by the user is the steam mode, and the controller controls the periodic operation of components such as the water inlet component and the steam generator.

[0088] In some embodiments, when the steam oven is running in the steam mode, the controller acquires the running duration of the water inlet component in the current working cycle.

[0089] S102, the controller acquires the number of first pulse signals when the running duration reaches a first preset duration.

[0090] In some embodiments, the first preset duration can be determined based on the running mode of the steam oven selected by the user. Specifically, according to the running mode, the target running duration of the water inlet component in the current working cycle can be determined, and then according to the target running duration, the first preset duration can be determined.

[0091] Optionally, the first preset duration can be m times of the target running duration, and m is a positive integer.

[0092] For example, when the steam oven is running in the steam mode, the target running duration of the water inlet component in the current working cycle corresponding to the steam mode is 1.5 seconds, and if the first preset duration is 2 times of the target running duration, then the first preset duration is 3 seconds.

[0093] Optionally, the first preset duration can also be pre-set by the management personnel when the steam oven is shipped, or can be acquired by the controller from other steam ovens, which is not limited.

[0094] It should be noted that in order to reduce the false detection rate of the steam tank abnormal state detection, the first preset time length should be set longer, and considering the timeliness of the steam tank abnormal state detection, the first preset time length should not be set too large.

[0095] In some embodiments, when the running time length reaches the first preset time length, the first pulse signal number is obtained by the flow detection component.

[0096] It can be understood that when the water inlet component is running, water in the water storage tank will be transported into the steam generator, so that the flow detection component can detect the water inlet amount of the steam generator. Further, the flow detection component generates a pulse signal based on the water inlet amount, and counts the pulse signals.

[0097] For example, the flow detection component detects 1 milliliter of water inlet amount, generates 50 pulse signals based on the 1 milliliter of water inlet amount, and records the number of pulse signals. In this way, when the running time length of the water inlet component is 1.5 seconds and the total water inlet amount detected by the flow detection component is 4 milliliters, the number of pulse signals recorded by the flow detection component is 200 pulse signals.

[0098] S103, the controller determines that the water storage tank is out of water when the first pulse signal number is less than the first preset pulse signal number.

[0099] In some embodiments, the first preset pulse signal number can be determined based on the user-selected running mode of the steam tank. Specifically, the controller can determine the target water inlet amount of the steam generator in the current working period according to the running mode, and generate a target pulse signal number based on the target water inlet amount, and then determine the first preset pulse signal number according to the target pulse signal number.

[0100] Optionally, the first preset pulse signal number is 1 / n times of the above-mentioned target pulse signal number, or the first preset pulse signal number is m / n times of the above-mentioned target pulse signal number, where n is a positive integer.

[0101] For example, when the steam tank runs in a steam mode, the target water inlet amount of the steam generator in the current working period corresponding to the steam mode is 7 milliliters, and the target pulse signal number corresponding to the target water inlet amount is 350. If the first pulse signal number is 1 / 3 times of the target pulse signal number, the first preset pulse signal number is 116. If the first preset pulse signal number is 2 / 3 times of the target pulse signal number, the first preset pulse signal number is 233.

[0102] Optionally, the first preset pulse signal number can also be pre-set by the management personnel when the steam tank is shipped, or can be obtained by the controller from other steam tanks, which is not limited.

[0103] In some embodiments, the controller determines that the water tank is out of water when the first number of pulse signals is less than a first preset number of pulse signals.

[0104] It should be noted that the ratio of the water inflow amount of the steam generator to the running time of the water inflow component in the current working period is the water inflow rate of the steam generator in the current working period. When the water amount in the water tank is sufficient, the water inflow rate of the steam generator is determined according to the ratio of the target water inflow amount to the target water inflow time, and the water inflow rate of the steam generator is the same even if the water inflow amount of the steam generator in each working period is different. When the water amount in the water tank is small, i.e., the water tank is out of water, in order to meet the target water inflow amount of the steam generator in the current working period, the water inflow component needs to extend the running time, so that the water inflow rate of the steam generator is reduced.

[0105] Therefore, a preset water inflow rate can be set, and when the water inflow rate is less than the preset water inflow rate, it is determined that the water tank is out of water. Specifically, a first preset number of pulse signals and a first preset time are set, and the ratio of the preset water inflow amount represented by the first preset number of pulse signals to the first preset time is the preset water inflow rate. Further, when the running time of the water inflow component reaches the first preset time, if the first number of pulse signals is less than the first preset number of pulse signals, it indicates that the water inflow rate of the steam generator is less than the preset water inflow rate, so that it can be determined that the water tank is out of water.

[0106] In some embodiments, the controller determines that the water tank is not out of water when the first number of pulse signals is greater than or equal to the first preset number of pulse signals, and controls the water inflow component to continue running so that the first number of pulse signals reaches the target number of pulse signals.

[0107] It can be understood that when the running time of the water inflow component reaches the first preset time, if the first number of pulse signals is greater than or equal to the first preset number of pulse signals, it indicates that the water inflow rate of the steam generator is greater than or equal to the preset water inflow rate, so that it can be determined that the water tank is not out of water. In order to reach the target water inflow amount in the current working period, the controller controls the water inflow component to continue running.

[0108] In some embodiments, the controller sends prompt information for prompting that the water tank is out of water when it is determined that the water tank is out of water.

[0109] Optionally, the controller can send the prompt information for prompting that the water tank is out of water to a voice device to send a voice prompt to the user that the water tank is out of water.

[0110] Optionally, the controller can also send the prompt information for prompting that the water tank is out of water to a display panel to display a prompt to the user that the water tank is out of water.

[0111] In some embodiments, the controller can also obtain the first pulse signals through the flow detection component when the running duration of the water inlet component does not reach the first preset duration, and determine that the water storage tank is out of water when the number of the first pulse signals is greater than or equal to the first preset number of pulse signals.

[0112] Based on Figure 6 In the embodiments shown in the drawings, the control method of the steam oven is provided. When the steam oven is running in the steam mode and the running duration of the water inlet component reaches the first preset duration, the number of first pulse signals is obtained through the flow detection component, and it is determined that the water storage tank is out of water when the number of first pulse signals is less than the first preset number of pulse signals. It can be understood that the number of pulse signals is used to represent the water inlet amount of the steam generator. When the running duration reaches the first preset duration, if the number of first pulse signals is less than the first preset number of pulse signals, that is, the first water inlet amount of the steam generator is less than the preset water inlet amount, it can be determined that the water inlet component is difficult to deliver the preset water inlet amount of water from the water storage tank to the steam generator within the first preset duration, and thus it can be determined that the water storage tank is out of water. In this way, the detection of the water storage tank being out of water according to the number of pulse signals detected by the flow detection component can timely and accurately detect the abnormal state of the water storage tank being out of water without the need to increase additional detection components, thereby avoiding the adverse effects of the water storage tank being out of water on user experience.

[0113] In some embodiments, before obtaining the number of first pulse signals, that is, before step S102, the control method further includes the following steps: Figure 7

[0114] S201, the controller obtains the number of second pulse signals when the running duration reaches the second preset duration.

[0115] In some embodiments, the second preset duration is determined based on the running mode of the steam oven selected by the user. Specifically, the controller can determine the target running duration of the water inlet component in the current working period according to the running mode, and the target running duration is the second preset duration.

[0116] In some embodiments, the second preset duration is determined based on the running mode of the steam oven selected by the user. Specifically, the controller can determine the target running duration of the water inlet component in the current working period according to the running mode, and the target running duration is the second preset duration.

[0117] In addition, the target running duration is consistent with the target running duration in step S102, and it can be understood that the controller can determine the second preset duration, and thus the first preset duration in step S102.

[0118] In some embodiments, the controller obtains the number of second pulse signals when the running duration reaches the second preset duration.

[0119] ​S202, the controller determines that the water tank is not out of water in a case where the second pulse signal number is greater than or equal to the second preset pulse signal number, and controls the water inlet component to stop running.

[0120] The second preset pulse signal number is greater than or equal to the first preset pulse signal number.

[0121] In some embodiments, the second preset pulse signal number is determined based on a user-selected running mode of the steam box. Specifically, the controller can determine a target water inlet amount of the steam generator in the current working period according to the running mode, and convert the target water inlet amount into a corresponding target pulse signal number, which is the second preset pulse signal number.

[0122] In addition, the target pulse signal number is consistent with the target pulse signal number in step S103, and it can be understood that the controller can determine the second preset pulse signal number according to the running mode, and then determine the first preset pulse signal number in step S103.

[0123] In some embodiments, the controller determines that the water tank is not out of water in a case where the second pulse signal number is greater than or equal to the second preset pulse signal number, and controls the water inlet component to stop running.

[0124] It can be understood that when the running duration of the water inlet component reaches the second preset duration, if the second pulse signal number is greater than or equal to the second preset pulse signal number, it means that the water inlet rate of the steam generator is greater than or equal to the water inlet rate of the steam generator in the case where the water tank is full of water, so that it can be determined that the water tank is not out of water. Since the second pulse signal number is greater than or equal to the second preset pulse signal number, that is, the water inlet amount of the steam generator reaches the target water inlet amount in the current working period, the water inlet component is controlled to stop running, and then the steam generator starts running.

[0125] S203, the controller controls the water inlet component to continue running in a case where the second pulse signal number is less than the second preset pulse signal number.

[0126] It can be understood that when the running duration of the water inlet component reaches the second preset duration, if the second pulse signal number is less than the second preset pulse signal number, it means that the water inlet rate of the steam generator is less than the water inlet rate of the steam generator in the case where the water tank is full of water, but it cannot be determined whether the water inlet rate of the steam generator is less than the preset water inlet rate. Therefore, the water inlet component is controlled to continue running, and when the running duration reaches the first preset duration, it is determined again whether the first pulse signal number is less than the first preset pulse signal number, and then it is determined whether the water tank is out of water.

[0127] In some embodiments, as Figure 8As shown, the control method further includes the following steps:

[0128] S301, the controller acquires the operation mode and the set temperature of the steamer.

[0129] The operation mode includes a steam mode and a non-steam mode. In addition, referring to the description of the steam mode in step S101, the steam mode specifically includes a pure steaming mode, a high-temperature steaming mode, a tender roasting mode, etc.

[0130] In some embodiments, in addition to selecting the operation mode of the steamer through the operation panel of the steamer, the user can also select the set temperature. Based on the operation mode and the set temperature selected by the user, the controller controls the steamer to operate in the operation mode and the set temperature. For example, the operation mode selected by the user is the pure steaming mode in the steam mode, and the set temperature selected by the user is 100 degrees Celsius, and the controller controls the steamer to operate in the pure steaming mode and 100 degrees Celsius.

[0131] Further, the controller acquires the operation mode and the set temperature of the steamer.

[0132] S302, the controller determines the target water inlet amount of the steam generator in the current working period and the second preset time corresponding to the target water inlet amount according to the operation mode and the set temperature.

[0133] In some embodiments, the target water inlet amount and the second preset time have a preset corresponding relationship, and the preset corresponding relationship includes the operation mode, the set temperature, the target water inlet amount, and the second preset time.

[0134] Optionally, the above-mentioned preset corresponding relationship can be pre-set by the management personnel when the steamer is shipped, or can be acquired by the controller from other steamers, which is not limited.

[0135] In some embodiments, based on the above-mentioned preset corresponding relationship, the controller determines the target water inlet amount of the steam generator in the current working period and the second preset time corresponding to the target water inlet amount according to the operation mode and the set temperature.

[0136] Exemplarily, the preset corresponding relationship between the operation mode and the set temperature and the target water inlet amount and the second preset time can be as shown in Table 1.

[0137] Table 1

[0138]

[0139]

[0140] In the pure steam mode, when the set temperature is 100 degrees Celsius, the target water inlet amount of the steam generator in the current working period is determined to be 7 milliliters, and the second preset time corresponding to the target water inlet amount is 1.5 seconds. For example, in the high-temperature steam mode, when the set temperature is 115 degrees Celsius, the target water inlet amount of the steam generator in the current working period is determined to be 10 milliliters, and the second preset time corresponding to the target water inlet amount is 2.5 seconds.

[0141] S303, the controller converts the target water inlet amount into the second preset pulse signal number according to the preset parameter of the flow detection component.

[0142] The preset parameter is used to represent the preset correspondence between the water inlet amount and the pulse signal number. For example, one milliliter of water inlet amount corresponds to 50 pulse signals, or one milliliter of water inlet amount corresponds to 60 pulse signals.

[0143] In some embodiments, the controller converts the target water inlet amount into the second preset pulse signal number according to the preset parameter of the flow detection component.

[0144] For example, when the target water inlet amount is 7 milliliters and the preset parameter is that one milliliter of water inlet amount corresponds to 50 pulse signals, the controller converts the target water inlet amount into 350 pulse signals, that is, the second preset pulse signal number is 350.

[0145] The complete process of the steam box completing the water shortage detection of the water storage box is exemplarily introduced as follows:

[0146] As shown in Figure 9 The detection process starts:

[0147] S11, the controller obtains the running mode and the set temperature of the steam box.

[0148] S12, the controller determines the target water inlet amount and the second preset time of the steam generator in the current working period according to the running mode and the set temperature.

[0149] S13, the controller converts the target water inlet amount into the second preset pulse signal number according to the preset parameter of the flow detection component.

[0150] S14, the controller controls the water inlet component to run and obtains the running time of the water inlet component.

[0151] It is judged whether the running time reaches the second preset time.

[0152] If yes, step S15 is executed.

[0153] If not, step S14 is continuously executed until the running time reaches the second preset time.

[0154] S15, the controller acquires the second pulse signal number.

[0155] determining whether the second pulse signal number is greater than or equal to a second preset pulse signal number.

[0156] If yes, step S19 is performed.

[0157] If no, step S16 is performed.

[0158] S16, the controller controls the water inlet component to continue running and acquires the running duration of the water inlet component.

[0159] determining whether the running duration reaches a first preset duration.

[0160] If yes, step S17 is performed.

[0161] If no, step S16 is continuously performed until the running duration reaches the first preset duration.

[0162] S17, the controller acquires the first pulse signal number.

[0163] determining whether the first pulse signal number is less than a first preset pulse signal number.

[0164] If yes, step S18 is performed.

[0165] If no, step S19 is performed.

[0166] S18, determining that the water tank is out of water.

[0167] S19, determining that the water tank is not out of water.

[0168] The above embodiments focus on how to quickly and accurately detect the abnormal state of the water tank in the control method of the steam oven provided by the embodiments of the present application. In some embodiments, the control method of the steam oven provided by the embodiments of the present application also includes how to quickly and accurately detect the abnormal state of the steam generator, such as Figure 10 As shown in the figure, the control method further includes the following steps:

[0169] S401, the controller acquires the continuous running duration of the steam generator.

[0170] It should be noted that the running duration of the steam generator in each working cycle corresponding to different running modes is different, and the temperature of the steam generator is also different. Therefore, when detecting the abnormal state of the steam generator, the controller detects according to the continuous running duration of the steam generator.

[0171] S402, the controller acquires the first temperature of the steam generator when the continuous running duration reaches a third preset duration.

[0172] In some embodiments, the controller acquires the first temperature of the steam generator by the temperature sensor when the continuous running duration reaches a third preset duration.

[0173] Optionally, the third preset duration can be preset by the administrator when the steam generator is manufactured, or can be acquired by the controller from other steam generators, which is not limited.

[0174] S403, the controller sends prompt information for prompting the abnormality of the steam generator when the first temperature is less than a first preset temperature.

[0175] Optionally, the first preset temperature is 100 degrees Celsius.

[0176] It should be noted that, since the water level of the water transported to the steam generator by the water inlet component is close to the installation position of the temperature sensor, before the steam generator starts to work, the temperature detected by the temperature sensor is close to the temperature of the unheated water in the water tank, which is less than 100 degrees Celsius. After the steam generator starts to work, if the steam generator does not appear abnormal, the steam generator will heat the water in the steam generator to boiling to generate steam, based on the boiling point of water, at this time, the temperature detected by the temperature sensor will be greater than or equal to 100 degrees Celsius. If the steam generator appears abnormal, the water in the steam generator will not be heated, and at this time, the temperature detected by the temperature sensor will be less than 100 degrees Celsius. Therefore, the controller sends prompt information for prompting the abnormality of the steam generator when the first temperature is less than the first preset temperature.

[0177] Optionally, the controller can send the prompt information for prompting the abnormality of the steam generator to the voice device to send voice prompt of the abnormality of the steam generator to the user.

[0178] Optionally, the controller can also send the prompt information for prompting the abnormality of the steam generator to the display panel to display the prompt of the abnormality of the steam generator to the user.

[0179] It should be noted that, Figure 10 The embodiments shown are performed when the running mode of the steam generator is the steam mode.

[0180] Based on Figure 10 Based on the embodiments shown, the application provides a control method of a steam generator, which sends prompt information for prompting the abnormality of the steam generator when the continuous running duration of the steam generator reaches a third preset duration, and the first temperature of the steam generator acquired at this time is less than a first preset temperature. In this way, after the user selects the running mode and the set temperature of the steam generator, the user can be prompted in time and accurately about the abnormality of the steam generator, thereby avoiding the poor user experience caused by the user discovering that the food material does not change until determining that the steam generator is abnormal.

[0181] The complete process of the steam generator abnormality detection of the steam oven is exemplarily introduced as follows:

[0182] As shown in Figure 11 , the detection process starts:

[0183] S21, the controller controls the steam generator to run.

[0184] S22, the controller acquires the continuous running duration of the steam generator.

[0185] It is judged whether the continuous running duration reaches the third preset duration.

[0186] If yes, step S23 is executed.

[0187] If no, step S21 and step S22 are continuously executed until the continuous running duration reaches the third preset duration.

[0188] S23, the first temperature of the steam generator is acquired.

[0189] It is judged whether the first temperature is less than the first preset temperature.

[0190] If yes, step S24 is executed.

[0191] If no, step S25 is executed.

[0192] S24, prompt information for prompting the abnormality of the steam generator is sent out.

[0193] S25, it is determined that the steam generator does not have abnormality.

[0194] The above embodiments focus on how to quickly and accurately detect the abnormal state of the steam generator in the control method of the steam oven provided by the embodiments of the present application. In some embodiments, the control method of the steam oven provided by the embodiments of the present application also includes how to quickly and accurately detect the abnormal state of the controller. As shown in Figure 12 , the control method further includes the following steps:

[0195] S501, the controller acquires the second temperature of the steam generator before the water inlet component runs in the current working cycle.

[0196] In some embodiments, if the user selects the running mode of the steam oven as the steam mode, the controller first controls the water in the steam generator and the water vapor separator to be transported to the water storage tank by the water drainage assembly when starting to run the steam mode.

[0197] Further, after the water in the steam generator and the water vapor separator is transported to the water storage tank by the water drainage assembly, the second temperature of the steam generator is acquired by the temperature sensor before the water inlet component runs in the current working cycle.

[0198] It can be understood that the second temperature obtained before the water inlet component operates in the current working cycle is the second temperature obtained before the steam generator operates.

[0199] In other embodiments, if the user selects the operation mode of the steam tank to be the non-steam mode, the second temperature of the steam generator is directly obtained by the temperature sensor.

[0200] It can be understood that, in the case that the operation mode of the steam tank is the non-steam mode, the controller does not need to control the operation of components such as the water inlet component and the steam generator, and therefore, the second temperature of the steam generator can be directly obtained by the temperature sensor.

[0201] S502, the controller issues prompt information for prompting the abnormality of the controller when the second temperature is greater than or equal to the second preset temperature.

[0202] The second preset temperature is greater than or equal to the first preset temperature, and the second preset temperature is less than the third preset temperature.

[0203] Optionally, the second preset temperature can be pre-set by the administrator when the steam tank is shipped, or can be obtained by the controller from other steam tanks, which is not limited.

[0204] It should be noted that, when the controller is not abnormal, in the case that the steam tank operates in the non-steam mode, or in the case that the steam tank operates in the steam mode and the steam generator operates before the current working cycle, the steam generator will not operate, and therefore, the temperature of the steam generator will not be greater than or equal to the second preset temperature. When the controller is abnormal, the steam generator operates, and the temperature of the steam generator will rapidly rise, and therefore, the temperature of the steam generator will be greater than or equal to the second preset temperature. Therefore, the controller issues the prompt information for prompting the abnormality of the controller when the second temperature is greater than or equal to the second preset temperature, so as to prompt the user that the controller is abnormal, and the controller controls the steam generator to operate when the steam generator does not need to operate.

[0205] Optionally, the controller can send the prompt information for prompting the abnormality of the controller to the voice device, so as to issue the voice prompt of the abnormality of the controller to the user.

[0206] Optionally, the controller can also send the prompt information for prompting the abnormality of the controller to the display panel, so as to display the prompt of the abnormality of the controller to the user.

[0207] Based on Figure 12In the embodiment shown, the embodiment of the present application provides a control method of the steam oven. Before the water inlet component operates in the current working period, if the second temperature of the steam generator obtained is greater than or equal to the second preset temperature, prompt information for prompting the controller abnormality is sent. In this way, after the user selects the operation mode and the set temperature of the steam oven, the controller abnormality can be timely and accurately prompted to the user to prevent the dry burning from occurring.

[0208] The complete process of the steam oven completing the controller abnormality detection is exemplarily introduced as follows:

[0209] As shown in the embodiment, Figure 13 The detection process starts.

[0210] S31, the controller obtains the operation mode selected by the user.

[0211] It is judged whether the operation mode selected by the user is the steam mode.

[0212] If yes, step S32 is executed.

[0213] If no, step S33 is executed.

[0214] S32, the controller obtains the second temperature of the steam generator before the water inlet component operates in the current working period.

[0215] S33, the controller directly obtains the second temperature of the steam generator.

[0216] S34, the controller sends prompt information for prompting the controller abnormality when the second temperature is greater than or equal to the second preset temperature.

[0217] In other embodiments, in the case that the steam oven does not have the flow detection component, the controller can determine whether the water storage tank is out of water by the temperature of the steam generator detected by the temperature sensor.

[0218] In some embodiments, the controller obtains the third temperature of the steam generator by the temperature sensor when the steam generator operates. And the fourth temperature of the steam generator is obtained by the temperature sensor after the water inlet component operates. In the case that the fourth temperature is greater than or still equal to the third temperature, it is determined that the water storage tank is out of water.

[0219] It should be noted that in the case that the water storage tank has sufficient water, when the controller controls the water inlet component to deliver water to the steam generator, the temperature of the steam generator will decrease. And in the case that the water storage tank is out of water, since the amount of water delivered to the steam generator by the controller controlling the water inlet component is small, the temperature of the steam generator will not decrease. Therefore, in the case that the fourth temperature is greater than or still equal to the third temperature, it is determined that the water storage tank is out of water.
