Description

Technical Field

[0001] The utility model relates to the technical field of cooking appliances, and particularly relates to a cooking appliance. Background Art

[0002] At present, in steam ovens or steamers sold on the market, usually only a single evaporation tray is provided inside. In actual use, the single evaporation tray has a weak ability to control the temperature of the internal steam, and it is easy to have the situation of overshoot of the internal temperature or too low internal temperature.

[0003] For example, after heating the temperature inside the cavity to the set temperature, even if the evaporation tray is controlled to stop working, due to the residual temperature of the evaporation tray, steam will still be generated and further increase the actual temperature inside the cavity, thus easily resulting in the situation of overheating of the cavity temperature. If the evaporation tray is controlled to stop working in advance before reaching the set temperature, plus the heat loss inside the cavity, it is easy to have the situation that the cavity temperature cannot be heated to the set temperature.

[0004] Therefore, the utility model aims to provide a cooking appliance with more accurate temperature control. Content of the Utility Model

[0005] In view of this, the utility model provides a cooking appliance to solve the problem that the current cooking appliance has a weak temperature control ability, resulting in easy overshoot of the internal temperature or too low internal temperature.

[0006] In a first aspect, the utility model provides a cooking appliance, which includes:

[0007] A box body provided with an inner container;

[0008] A temperature detection mechanism for detecting the current temperature of the inner container;

[0009] An evaporation mechanism arranged at the bottom of the inner container and communicatively connected with the temperature detection mechanism; two evaporators and a water inlet assembly are arranged in the evaporation mechanism, at least one evaporation tray is arranged in each evaporator, and the water inlet assembly is used for supplying water to the evaporation tray; the total power of the first evaporator is greater than that of the second evaporator.

[0010] Beneficial effects: In the embodiment of the present utility model, the total power of the first evaporator can be set larger, which is suitable for quickly raising the temperature and providing a large amount of steam when needed. When the actual temperature difference is large, the working time of the first evaporator is longer, increasing the heat input to ensure rapid temperature rise; when the actual temperature difference is small, in order to avoid temperature overshoot, the working time of the first evaporator is shorter, reducing the heat input, thereby reducing the temperature rise rate in the inner container, so that the temperature of the inner container slowly approaches the predetermined temperature, and during the slow temperature rise process, efficient and precise temperature control can be achieved. At the same time, since the power of the second evaporator is low, it can ensure continuous operation, maintain a stable steam environment and temperature environment, and ensure the coherence of the entire temperature control process. At the same time, technicians and users can flexibly control the steam generation rate and steam generation amount by changing the number or power of the evaporators in the evaporation mechanism. Further, technicians can also adjust the heating duration of the two evaporators in different working stages to achieve at least multiple modes such as rapid temperature rise mode and constant temperature mode, so as to meet different needs of users for cooking utensils.

[0011] In an alternative embodiment, a first evaporation tray is provided in the first evaporator, and a second evaporation tray is provided in the second evaporator, and the power of the first evaporation tray is greater than that of the second evaporation tray.

[0012] Beneficial effects: In the embodiment of the present utility model, by providing only one evaporation tray in each evaporator, while ensuring that the cooking utensil can accurately control the temperature normally, the production cost can be reduced. Further, in actual application, the first evaporation tray can use an evaporation tray with a currently common power, and the second evaporation tray can use an evaporation tray with a smaller power, or adjust the evaporation tray with a common power to make the power smaller. In this way, there is no need to customize or purchase an evaporation tray with a smaller power additionally, and to a certain extent, the production cost can be further reduced.

[0013] In an alternative embodiment, the water inlet assembly includes:

[0014] a first water inlet pipe, a second water inlet pipe and a switching valve. The water outlet end of the first water inlet pipe extends into the first evaporator after passing through the inner container; the water outlet end of the second water inlet pipe extends into the second evaporator after passing through the inner container; the water inlet ends of the first water inlet pipe and the second water inlet pipe are connected to a water source, and the switching valve is used to control the on-off of the first water inlet pipe and the second water inlet pipe;

[0015] The cross-sectional area of the first water inlet pipe is larger than that of the second water inlet pipe.

[0016] Beneficial effects: Since the total power of the first evaporator is greater than that of the second evaporator, in the embodiment of the present utility model, by making the cross-sectional area of the first water inlet pipe larger than that of the second water inlet pipe, it can ensure that the water supply to the first evaporator is greater than that to the second evaporator, thus ensuring the normal operation of the first evaporator. This avoids the situation where, with the same water supply, the water consumption of the second evaporator can be met while the water consumption of the first evaporator cannot be satisfied, achieving differential water supply.

[0017] In an alternative embodiment, an area ratio is formed between the cross-sectional area of the first water inlet pipe and that of the second water inlet pipe, and a power ratio is formed between the total power of the first evaporator and that of the second evaporator; the area ratio is directly proportional to the power ratio.

[0018] Beneficial effects: In the embodiment of the present utility model, by corresponding the area ratio with the power ratio, the water supply can be made to correspond to the water consumption, thus ensuring that the cooking appliance will not dry out or the water supply will be too large, causing overflow from the inner container, and further ensuring the normal operation of the cooking appliance.

[0019] In an alternative embodiment, the water inlet assembly further includes a main water inlet pipe and a three-way pipe, and the switching valve includes a first switching valve and a second switching valve;

[0020] The water inlet end of the main water inlet pipe is connected to the water source, the water outlet end of the main water inlet pipe is communicated with the water inlet end of the three-way pipe, the first water outlet end of the three-way pipe is communicated with the water inlet end of the first water inlet pipe, and the second water outlet end of the three-way pipe is communicated with the water inlet end of the second water inlet pipe; the first switching valve is arranged on the first water inlet pipe to control the on-off of the first water inlet pipe, and the second switching valve is arranged on the second water inlet pipe to control the on-off of the second water inlet pipe.

[0021] In an alternative embodiment, the water inlet assembly further includes a main water inlet pipe, and the switching valve is a three-way valve;

[0022] The water inlet end of the main water inlet pipe is connected to the water source, the water outlet end of the main water inlet pipe is communicated with the water inlet end of the three-way valve, the first water outlet end of the three-way valve is communicated with the water inlet end of the first water inlet pipe, and the second water outlet end of the three-way valve is communicated with the water inlet end of the second water inlet pipe; the three-way valve controls the on-off of the first water inlet pipe and the second water inlet pipe.

[0023] In an alternative embodiment, the water inlet assembly further includes a water tank, and the water outlet end of the water tank is communicated with the water inlet end of the main water inlet pipe.

[0024] In an alternative embodiment, the cooking appliance further includes:

[0025] The blower assembly, and a ventilation hole is provided in the inner container at a position corresponding to the blower assembly.

[0026] Advantageous effects: Since the powers of the two evaporators are different, during the cooking process, the amounts of steam generated in the inner container spaces corresponding to their respective upper parts are also different, resulting in uneven temperature distribution in the inner container space, which easily causes uneven heating of the food and leads to some food being undercooked or overcooked. In the embodiment of the present utility model, by providing a blower assembly, on the one hand, the steam environment in the inner container can be evenly distributed. Under the action of the air flow, the steam in the inner container will circulate, so that the internal temperature becomes more uniform. On the other hand, it can also accelerate the steam circulation in the inner container, thereby accelerating the evaporation of water, improving the evaporation efficiency, and further accelerating the cooking efficiency of the food, making the cooking process more efficient.

[0027] In an optional embodiment, the blower assembly includes:

[0028] A pair of first blowers, which are arranged on the box body and are respectively located on two sides of the inner container; the first blowers blow air into the interior of the inner container in the horizontal direction;

[0029] A second blower, which is arranged on the box body and is located on the top surface of the inner container; when the second blower blows air into the interior of the inner container, it forms a steam internal circulation with the steam generated by each evaporator.

[0030] Advantageous effects: In the embodiment of the present utility model, by providing a pair of first blowers, the hot air in the oven is circulated to form a convection cycle, which can evenly distribute the steam at each position in the horizontal space and ensure that the temperature at each corner inside the inner container is uniform. Compared with only setting one blower on one side, one blower can directly blow to the space where the other blower is located, so as to distribute the steam in this space. After the steam is evenly distributed at each position in the space, the temperature in the inner container space can be significantly evenly distributed. Further, since the space not occupied above the current box body itself is relatively small, it is impossible to additionally install other large components above the box body. And in this embodiment, by providing a second blower, the second blower can be a small blower, so that while making full use of the top space, it can further evenly the temperature field in the inner container and ensure a better cooking effect for the user. Moreover, the air flow generated by the second blower will not directly blow against the evaporator, so it will not disperse the steam generated by the evaporator, but can blow in other directions inside the inner container, making the cold air flow generated by the second blower move downward and the hot steam generated by the evaporator move upward, so as to form a steam internal circulation with the steam generated by each evaporator, and further evenly the temperature field in the inner container and ensure a better cooking effect for the user.

[0031] In an alternative embodiment, two evaporation trays are symmetrically arranged at intervals on the left and right at the bottom of the inner container, and the second blower is arranged directly above the middle position between the two evaporation trays.

[0032] Beneficial effects: In the embodiment of the present utility model, by arranging the evaporation mechanism at the bottom of the inner container, the internal space of the inner container can be utilized more effectively, so that the water in the cooking appliance can directly contact the surface of the evaporator. After generating steam, the steam can be more quickly and evenly distributed throughout the oven interior, thereby improving the cooking efficiency and the moisture of the food. Further, when generating steam, the steam will directly be released along the space corresponding to the upper part of the evaporator, and then, in cooperation with the cold air blown between the two evaporators, a better steam internal circulation can be formed, and further, the temperature field in the inner container can be made uniform, ensuring a better cooking effect for the user.

[0033] In an alternative embodiment, the second blower takes in air from the side and blows air into the interior of the inner container in the vertical direction.

[0034] Beneficial effects: In the embodiment of the present utility model, by changing the air flow direction of the second blower from the air intake mode of the ordinary blower from the top to the bottom to the air intake mode from the side to the bottom, on the one hand, compared with the ordinary blower, the space occupied in the vertical direction is significantly reduced, and the space of the air intake part of the blower is moved from the top of the blower to the side of the blower, so as not to affect the space occupied above the box body. On the other hand, taking in air from the side can significantly expand the air intake area of the blower, and compared with only taking in air from the top of the blower, the air volume can be significantly increased.

[0035] In an alternative embodiment, the cooking appliance further includes:

[0036] A heating component, arranged on the top wall inside the inner container; the heating component is arranged in a meandering layout in a plurality of bent shapes and is correspondingly arranged with the ventilation holes at the top of the inner container.

[0037] Beneficial effects: When the first evaporator stops operating, the temperature inside the inner container will rapidly drop, so that the excess steam in the inner container will condense, forming water droplets on the surface of the food in the inner container or on the side wall of the inner container, thereby affecting the taste of the food. In the embodiment of the present utility model, by arranging the heating component, when the first evaporator stops running, the heating component and the second blower can be started to work. The second blower blows out cold air through the ventilation holes, and after being heated by the heating component, hot air can be formed, so as to timely dry the excess steam in the inner container, thereby avoiding the condensation of the steam, and further being able to ensure the taste of the food and improve the user experience. At the same time, the condensed water can be evaporated again, improving the utilization rate of the condensed water. And, the heating component is arranged in a meandering layout in a plurality of bent shapes, which can significantly increase the heating area of the heating component and improve the drying efficiency to a certain extent.

[0038] In an alternative embodiment, the heating component has an intermittent working state, and the heating component is only activated during the period when the first evaporator pauses.

[0039] Advantageous effects: In the embodiment of the present utility model, by also making the heating component work intermittently and completely staggering its working time from that of the first evaporator, when the first evaporator generates steam, the heating component stops operating, avoiding the reduction of steam in the inner container. When the first evaporator does not generate steam, the heating component starts to operate, thereby drying the excess steam in the inner container, avoiding the condensation of steam, and further ensuring the taste of food and improving the user experience.

[0040] In an alternative embodiment, the cooking appliance further comprises:

[0041] A baking bracket disposed on the inner side wall of the inner container; the baking bracket is correspondingly disposed with the ventilation holes on the inner side wall of the inner container.

[0042] Advantageous effects: In the embodiment of the present utility model, by correspondingly disposing the baking bracket at the position of the ventilation holes, when the cooking appliance has both steaming and baking functions, the first blower can also evenly disperse the heat generated by the baking bracket into the inner container, so that during baking, the temperature in the inner container can also be evenly distributed, further meeting the user's usage requirements.

[0053] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0054] The following combines Figures 1 to 7 , to describe the embodiments of the present utility model.

[0055] According to an embodiment of the present utility model, on the one hand, a cooking appliance is provided, and the cooking appliance includes a box body 1, an evaporation mechanism and a temperature detection mechanism.

[0056] Specifically, in the embodiment of the present utility model, as Figure 1 shown, the cooking appliance can be equipment such as a steam oven or a steamer, and has a steaming function. An inner container 11 is arranged in the box body 1 of the cooking appliance, and food is placed in the inner container 11 for cooking.

[0057] Furthermore, in the embodiment of the present utility model, the temperature detection mechanism can be arranged inside the inner container 11 or outside the inner container 11, and the temperature detection mechanism is used to detect the current temperature inside the inner container 11. The temperature detection mechanism can be a temperature sensor, an infrared sensor or a thermal resistor and other devices.

[0058] Certainly, in the embodiment of the present utility model, only the specific types of the temperature detection mechanism are illustrated, but are not limited thereto. Those skilled in the art can make changes according to actual situations as long as the same technical effects can be achieved.

[0059] Further, in the embodiment of the present utility model, as Figure 1 , Figure 4 , Figure 6 , Figure 7 shown, the evaporation mechanism is arranged at the bottom of the inner container 11. The evaporation mechanism can be communicatively connected to the main control of the cooking appliance, and the main control can also be communicatively connected to the temperature detection mechanism, so that the working mode of the evaporation mechanism is linked with the actual temperature detected by the temperature detection mechanism in the inner container 11.

[0060] Specifically, in the embodiment of the present utility model, the evaporation mechanism is provided with a water inlet assembly 8 and two evaporators. The water inlet assembly 8 is used to supply water to the evaporation tray. At least one evaporation tray is arranged in each evaporator. The total power of the first evaporator is greater than that of the second evaporator. The evaporation device of the first evaporator can still adopt the evaporation device commonly used in the current steam box or steam oven, so that the existing device can be directly used without additional customization. On this basis, a certain production cost can be reduced.

[0061] For the first evaporator, the purpose is to quickly increase the temperature in combination with the second evaporator after startup. For the second evaporator, it only needs to ensure that the temperature of the inner container 11 does not drop. Therefore, those skilled in the art can select evaporation devices with appropriate power according to the actual situation. The specific power size is not limited in this embodiment, as long as the same technical effect can be achieved.

[0062] Further, during the actual working process, the first evaporator has an intermittent working state, and the second evaporator has a maintaining working state. That is to say, the first evaporator has a working cycle. In each working cycle, the first evaporator will work normally for a period of time and stop working for another period of time. In the intermittent cycle of the first evaporator, that is, in each working cycle of the first evaporator, the working time of the first evaporator is proportional to the actual temperature difference. The actual temperature difference is the difference between the current temperature and the predetermined temperature, where the current temperature is the temperature of the inner container 11, and the predetermined temperature is the cooking temperature set by the user during use.

[0063] When the actual temperature difference is larger, it indicates that the current temperature in the inner container 11 is lower, and more steam needs to be quickly generated for cooking, so the working time of the first evaporator is longer. When the actual temperature difference is smaller, it indicates that the current temperature in the inner container 11 is higher, and the first evaporator needs to reduce its working time. Thus, the temperature of the inner container 11 can be slowly increased by relying on the small amount of heat brought by the first evaporator and the temperature maintained by the second evaporator, so that the current temperature of the inner container 11 gradually approaches the predetermined temperature, thereby achieving efficient and precise temperature control.

[0064] With such a setting, the total power of the first evaporator in the embodiment of the present utility model is greater, which is suitable for quickly raising the temperature and providing a large amount of steam when needed. The intermittent working mode can dynamically adjust the working time according to the actual temperature difference. When the actual temperature difference is large, it indicates that a large amount of heat is still needed. Therefore, in a single intermittent cycle, the working time of the first evaporator is longer to increase the heat input and ensure rapid temperature rise. When the actual temperature difference is small, in order to avoid overshoot of the temperature, in a single intermittent cycle, the working time of the first evaporator is shorter to reduce the heat input, thereby reducing the temperature rise rate in the inner container 11, so that the temperature of the inner container 11 slowly approaches the predetermined temperature, and during the slow temperature rise process, efficient and precise temperature control can be achieved. At the same time, since the power of the second evaporator is low, it can ensure continuous operation, maintain a stable steam environment and temperature environment, and ensure the coherence of the entire temperature control process. At the same time, since multiple evaporation trays can be installed inside each evaporator according to the actual situation, technicians and users can flexibly control the steam generation rate and steam generation amount. Further, technicians can also adjust the heating duration of the two evaporators in different working stages to enable the use of at least multiple modes such as rapid temperature rise mode and constant temperature mode, so as to meet different needs of users for cooking utensils.

[0065] Further, in an optional implementation manner, an example is given with a single evaporation tray provided in each evaporator. Specifically, as Figure 1 , Figure 4 , Figure 6 , Figure 7 shown, a first evaporation tray 2 is provided in the first evaporator, and a second evaporation tray 3 is provided in the second evaporator. Since a single evaporation tray is provided in each evaporator, the power of the first evaporation tray 2 is greater than that of the second evaporation tray 3.

[0066] Similarly, those skilled in the art can select evaporation trays with suitable power according to the actual situation. The specific power of each evaporation tray is not limited in this embodiment, as long as the same technical effect can be achieved.

[0067] With such a setting, in the embodiment of the present utility model, by providing only one evaporation tray in each evaporator, while ensuring that the cooking utensil can accurately control the temperature normally, the production cost can also be reduced. Further, in actual application, the first evaporation tray 2 can use an evaporation tray with a currently common power, and the second evaporation tray 3 can use an evaporation tray with a smaller power, or adjust the evaporation tray with a common power to make the power smaller. In this way, there is no need to customize or purchase evaporation trays with smaller power additionally, and to a certain extent, the production cost can be further reduced.

[0068] Further, in an optional implementation manner, as Figure 5As shown, the water inlet assembly 8 includes a first water inlet pipe 81, a second water inlet pipe 82, and a switching valve.

[0069] Specifically, in this embodiment, the water inlet ends of the first water inlet pipe 81 and the second water inlet pipe 82 are connected to a water source. After the water outlet end of the first water inlet pipe 81 passes through the inner tank 11, it extends into the first evaporator to supply water to the first evaporator. After the water outlet end of the second water inlet pipe 82 passes through the inner tank 11, it extends into the second evaporator to supply water to the second evaporator. The switching valve is used to control the on / off of the first water inlet pipe 81 and the second water inlet pipe 82.

[0070] Meanwhile, the cross-sectional area of the first water inlet pipe 81 is larger than the cross-sectional area of the second water inlet pipe 82.

[0071] With such a setting, since the total power of the first evaporator is greater than the total power of the second evaporator, in the embodiment of the present utility model, by making the cross-sectional area of the first water inlet pipe 81 larger than the cross-sectional area of the second water inlet pipe 82, it can be ensured that the water supply to the first evaporator is greater than the water supply to the second evaporator, so as to ensure the normal operation of the first evaporator. This avoids the situation where the water supply is the same, which can meet the water consumption of the second evaporator but cannot meet the water consumption of the first evaporator, realizing differential water supply.

[0072] Further, in an alternative embodiment, an area ratio is formed between the cross-sectional area of the first water inlet pipe 81 and the cross-sectional area of the second water inlet pipe 82, and a power ratio is formed between the total power of the first evaporator and the total power of the second evaporator; the area ratio is directly proportional to the power ratio.

[0073] With such a setting, in the embodiment of the present utility model, by corresponding the area ratio with the power ratio, the water supply can be made to correspond to the water consumption, so as to ensure that the cooking appliance will not dry out or the water supply is too large, resulting in overflow from the inner tank 11, and further ensure the normal operation of the cooking appliance.

[0074] The following describes the specific water inlet mode of the water inlet assembly 8.

[0075] Further, in an alternative embodiment, the water inlet assembly 8 further includes a main water inlet pipe 83 and a three-way pipe, and the switching valve includes a first switching valve and a second switching valve arranged in parallel.

[0076] Specifically, in the embodiment of the present utility model, the water inlet end of the main water inlet pipe 83 is connected to the water source, and the water source can be a faucet, a water tank, or a water pipe. The water outlet end of the main water inlet pipe 83 is communicated with the water inlet end of the three-way pipe. The first water outlet end of the three-way pipe is communicated with the water inlet end of the first water inlet pipe 81, and the second water outlet end of the three-way pipe is communicated with the water inlet end of the second water inlet pipe 82.

[0077] Further, the first on-off valve is arranged on the first water inlet pipe 81 to control the on-off of the first water inlet pipe 81, and the second on-off valve is arranged on the second water inlet pipe 82 to control the on-off of the second water inlet pipe 82.

[0078] Further, in a preferred embodiment, as Figure 5 shown, the water inlet assembly 8 further includes a main water inlet pipe 83, and the on-off valve is a three-way valve 84.

[0079] Similarly, the water inlet end of the main water inlet pipe 83 is connected to the water source, the water outlet end of the main water inlet pipe 83 is communicated with the water inlet end of the three-way valve 84, the first water outlet end of the three-way valve 84 is communicated with the water inlet end of the first water inlet pipe 81, and the second water outlet end of the three-way valve 84 is communicated with the water inlet end of the second water inlet pipe 82. The three-way valve 84 is used to control the on-off of the first water inlet pipe 81 and the second water inlet pipe 82.

[0080] Further, in an alternative embodiment, the water inlet assembly 8 further includes a water tank, and the water outlet end of the water tank is communicated with the water inlet end of the main water inlet pipe 83.

[0081] Further, in an alternative embodiment, as Figures 5 to 7 shown, the cooking appliance further includes a fan assembly 4. The fan assembly 4 is arranged on the cabinet 1 and is located outside the inner container 11. The inner container 11 is provided with a ventilation hole 5 at a position corresponding to the fan assembly 4 to ensure that the fan assembly 4 can normally transfer air to the inner container 11 through the ventilation hole 5. In the embodiment of the present utility model, the fan assembly 4 can be selected from types such as a centrifugal fan, an axial fan, or an inclined-flow exhaust fan.

[0082] Of course, this embodiment is only an example for illustrating the selection type of the fan assembly 4, but it is not limited thereto. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0083] With such a setting, since the powers of the two evaporators are different, during the cooking process, the amounts of steam generated in the corresponding inner pot 11 spaces above each of them are also different, resulting in uneven temperature distribution in the inner pot 11 space. This easily causes uneven heating of the food, leading to some food being undercooked or overcooked. In the embodiment of the present utility model, by providing the fan assembly 4, on the one hand, it can evenly distribute the steam environment in the inner pot 11. Under the action of the air flow, the steam in the inner pot 11 will circulate, thereby making the internal temperature more uniform. On the other hand, it can also accelerate the steam circulation in the inner pot 11, thereby accelerating the evaporation of water, improving the evaporation efficiency, and further accelerating the cooking efficiency of the food, making the cooking process more efficient.

[0084] Further, the fan assembly 4 and the box body 1 can be fixedly connected or detachably connected. For the fixed connection, welding, bonding and other methods can be adopted. For the detachable connection method, it can be fixed by means of screw holes, or by means of snap fasteners and slots, or by means of magnetic attraction between magnetic sheets.

[0085] The following gives examples of the detachable connection method. For example, a fixing plate can be additionally provided on the box body 1. Those skilled in the art can change the number of fixing plates according to the actual situation, such as 1, 2, 3, 4, etc. Then screw holes are opened on the fixing plate, and another screw hole is opened on the fan assembly 4 at the position corresponding to the screw hole. Then the screws are sequentially passed through the screw holes on the fixing plate and the screw holes on the fan assembly 4, so as to connect the box body 1 and the fan assembly 4. Further, when using the snap fastener and slot method for fixing, a snap fastener can be additionally provided on the box body 1. Those skilled in the art can change the number of snap fasteners according to the actual situation, such as 1, 2, 3, 4, etc. Then a slot that can cooperate with the snap fastener is opened on the fan assembly 4 at the position corresponding to the snap fastener. Then the snap fastener on the box body 1 is directly inserted into the slot on the fan assembly 4, so as to connect the box body 1 and the fan assembly 4. When using the magnetic attraction method for fixing, a magnetic sheet can be additionally provided on the box body 1. Those skilled in the art can change the number of magnetic sheets according to the actual situation, such as 1, 2, 3, 4, etc. Then a magnetic sheet of the opposite polarity that can be attracted by the magnetic sheet is opened on the fan assembly 4 at the position corresponding to the magnetic sheet. Then the magnetic sheet on the box body 1 is directly aligned and inserted into the magnetic sheet of the opposite polarity on the fan assembly 4, so as to magnetically connect the box body 1 and the fan assembly 4.

[0086] Certainly, this embodiment is only an example of the fixed connection method and the detachable connection method, but it is not limited thereto. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0087] Further, in an optional implementation manner, as Figures 5 to 7As shown, the blower assembly 4 includes a first blower 41 and a second blower 42.

[0088] Specifically, in the embodiment of the present utility model, there is a pair of first blowers 41, and both of the two first blowers 41 are arranged on the box body 1 and are respectively located on two sides of the inner tank 11. During actual application, the first blower 41 can blow air into the inner tank 11 in the horizontal direction. In this way, when the steam moves upward from the bottom, the steam can be blown from both sides to the middle, so that a hot air circulation is formed inside, ensuring uniform temperature inside the inner tank 11.

[0089] Meanwhile, the second blower 42 is arranged on the box body 1 and is located on the top surface of the inner tank 11, and the second blower 42 blows air into the inner tank 11. When the second blower 42 blows air into the inner tank 11, a steam internal circulation is formed with the steam generated by each evaporator. Considering that the distance between the top surface of the inner tank 11 and the top of the box body 1 is relatively small, the second blower 42 can be a small fan as long as it can be installed between the top of the inner tank 11 and the top of the box body 1. Of course, ventilation holes 5 need to be opened on the inner tank 11 at the corresponding positions of the first blower 41 and the second blower 42. The area of the ventilation holes 5 can correspond to the air outlet area of the first blower 41 and the second blower 42, or can be directly larger than the air outlet area, as long as it ensures that the first blower 41 and the second blower 42 can intake air normally.

[0090] With such a setting, in the embodiment of the present utility model, by arranging a pair of first blowers 41, the hot air in the oven can be circulated to form a convection cycle, which can evenly distribute the steam at each position in the horizontal space, ensuring uniform temperature at each corner inside the inner tank 11. Compared with only setting one blower on one side, one blower can directly blow to the space where the other blower is located, so as to distribute the steam in this space. After the steam is distributed at each position in the space, the temperature in the space of the inner tank 11 can be significantly evenly distributed. Further, since the space not occupied above the box body 1 itself is relatively small currently, it is impossible to additionally install other large components above the box body 1. And in this embodiment, by arranging the second blower 42, the second blower 42 can be a small blower, so that while making full use of the top space, it can further evenly the temperature field in the inner tank 11, ensuring a better cooking effect for users. Moreover, the air flow generated by the second blower 42 will not directly blow towards the evaporator, so it will not disperse the steam generated by the evaporator, but can blow in other directions inside the inner tank 11, making the cold air flow generated by the second blower 42 move downward and the hot steam generated by the evaporator move upward, so that a steam internal circulation can be formed with the steam generated by each evaporator, and further the temperature field in the inner tank 11 can be evenly, ensuring a better cooking effect for users.

[0091] Further, in an alternative embodiment, as Figure 6 shown, two through holes 111 are provided at the bottom of the inner container 11, and each evaporation tray is correspondingly arranged in the through hole 111, so that the evaporation tray is recessed at the bottom of the inner container 11. The gap between the two evaporation trays corresponds to the air outlet direction of the second blower 42. Specifically, the two evaporation trays can be symmetrically arranged at intervals left and right at the bottom of the inner container 11, and the second blower 42 is arranged directly above the middle position between the two evaporation trays.

[0092] With such an arrangement, in the embodiment of the present invention, by arranging the evaporation mechanism in the through hole 111 at the bottom of the inner container 11, the internal space of the inner container 11 can be more effectively utilized, so that the water in the cooking appliance can directly contact the surface of the evaporator. After generating steam, the steam can be more quickly and evenly distributed throughout the oven interior, thereby improving the cooking efficiency and the moisture of the food. Further, placing the evaporation mechanism in the recess at the bottom of the inner container 11 can facilitate the condensate to fall back onto the evaporation tray again, so that the condensate can be reused. At the same time, since the evaporation mechanism is located in a relatively closed through hole 111, during the actual cooking process, food residues and the water in the inner container 11 can be prevented from flowing to the outside, reducing the potential electrical safety hazards, and it is also convenient for the user to clean and maintain. Further, when generating steam, the steam will be directly released along the upper space corresponding to the recessed area of the evaporator, and then, in cooperation with the cold air blown between the two evaporators, a better steam internal circulation can be formed, and further, the temperature field in the inner container 11 can be made uniform, ensuring a better cooking effect for the user.

[0093] Further, in an alternative embodiment, as Figure 7 shown, the second blower 42 is provided with an air inlet side and an air outlet side. Currently, the air inlet side and the air outlet side of the blower are usually in one direction, that is to say, the air inlet direction and the air outlet direction are both on a straight line. In this embodiment, however, the air inlet side and the air outlet side of the second blower 42 are adjusted so that the second blower 42 takes in air from the side, for example, takes in air from all around in the horizontal direction and blows air into the interior of the inner container 11 in the vertical direction. Obviously, the length and volume of the second blower 42 in the air inlet direction can be reduced, and a part of the length and volume is transferred to the side.

[0094] With such an arrangement, in the embodiment of the present invention, by changing the air flow direction of the second blower 42 from the air inlet mode of the ordinary blower from the top to the bottom to the air inlet mode of taking in air from the side and blowing air out from the bottom, on the one hand, compared with the ordinary blower, the space occupied in the vertical direction is significantly reduced, and the space of the air inlet part of the blower is moved from the top of the blower to the side of the blower, so that the space occupied above the box body 1 will not be affected. On the other hand, taking in air from the side can significantly expand the air inlet area of the blower, and compared with only taking in air from the top of the blower, the air volume can be significantly increased.

[0095] Further, in an optional embodiment, as Figure 2 and Figure 3 As shown, the cooking utensil also includes a heating component 6, which is arranged on the top wall inside the inner pot 11, and the heating component 6 is arranged corresponding to the ventilation hole 5 on the top of the inner pot 11. The heating component 6 can be an electric heating tube, which is arranged at the ventilation hole 5 on the top and is arranged in a winding manner in a plurality of bending shapes. The heating component 6 is arranged in a winding manner in a plurality of bending shapes, which can significantly increase the heating area of ​​the heating component 6 and improve the drying efficiency to a certain extent. Of course, the heating component 6 can also adopt an electric heating sheet. In order to ensure that the second fan 42 can normally discharge air through the ventilation hole 5, a through hole can also be provided on the electric heating sheet corresponding to the ventilation hole 5.

[0096] This embodiment is merely an example of the structural form of the heating component 6, but does not limit it. Those skilled in the art can make changes according to actual conditions as long as the same technical effect can be achieved.

[0097] With such a configuration, when the first evaporator stops operating, the temperature in the inner tank 11 will drop rapidly, causing the excess steam in the inner tank 11 to condense, forming water droplets on the surface of the food in the inner tank 11 or on the side wall of the inner tank 11, thereby affecting the taste of the food. In the embodiment of the utility model, by providing a heating component 6, when the first evaporator stops operating, the heating component 6 and the second fan 42 can start working, and the second fan 42 blows out cold air through the ventilation hole 5. After being heated by the heating component 6, hot air can be formed, thereby timely drying the excess steam in the inner tank 11, thereby avoiding condensation of steam, and further ensuring the taste of the food, and improving the user experience.

[0098] Furthermore, in an optional embodiment, the heating component 6 is in communication connection with the temperature detection mechanism and the evaporation mechanism at the same time. The heating component 6 has an intermittent working state, and the heating component 6 starts working only during the time period when the first evaporator is paused. In the intermittent cycle of the heating component 6, the working time of the heating component 6 is proportional to the actual temperature difference.

[0099] That is to say, the heating component 6 works in conjunction with the evaporation mechanism. When the first evaporation mechanism works, the heating component 6 stops working. When the first evaporation mechanism stops working, the heating component 6 starts working, and the working time of the heating component 6 is related to the actual temperature difference of the inner tank 11.

[0100] Specifically, the greater the actual temperature difference is, the lower the current temperature in the inner container 11 is. At this time, steam is quickly generated for cooking. When the first evaporator stops working, the speed at which the steam turns into condensed water is faster, and the amount of condensed water generated is larger. Therefore, the heating component 6 needs to dry the condensed water for a long time. When the actual temperature difference is smaller, it indicates that the current temperature in the inner container 11 is higher. At this time, it is in a state of maintaining the temperature and slowly increasing the temperature of the inner container 11. When the first evaporator stops working, the temperature fluctuation is smaller, the speed at which the steam turns into condensed water is slower, and the amount of condensed water generated is smaller. Therefore, the working time of the heating component 6 will also be shorter.

[0101] With such a setting, in the embodiment of the present utility model, by also intermittently operating the heating component 6 and completely staggering the working time from that of the first evaporator, when the first evaporator generates steam, the heating component 6 stops operating, avoiding reducing the steam in the inner container 11. When the first evaporator does not generate steam, the heating component 6 starts to operate, thereby drying the excess steam in the inner container 11, avoiding the condensation of steam, and further ensuring the taste of the food and improving the user experience.

[0102] Further, in an optional embodiment, as Figures 1 to 3 、 Figure 6 and Figure 7 shown, the cooking appliance further includes a baking bracket 7, and the baking bracket 7 is arranged on the inner side wall of the inner container 11, and the baking bracket 7 is correspondingly arranged with the ventilation holes 5 on the inner side wall of the inner container 11. In this embodiment, when the cooking appliance is provided with both a baking bracket 7 and an evaporation mechanism, the cooking appliance is a steam oven with both baking and steaming functions.

[0103] With such a setting, in the embodiment of the present utility model, by correspondingly arranging the baking bracket 7 at the position of the ventilation holes 5, when the cooking appliance has both steaming and baking functions, the first blower 41 can also evenly disperse the heat generated by the baking bracket 7 into the inner container 11, so that during baking, the temperature distribution in the inner container 11 can also be ensured to be uniform, further meeting the user's usage requirements.

[0104] Although the embodiments of the present utility model have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations all fall within the scope defined by the appended claims.
