Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a cooking appliance and a temperature control method. Background Art

[0002] Cooking appliances are used to prepare a wide variety of delicious dishes. Combination steam ovens, for example, are becoming increasingly popular because they combine the functions of a steamer and an oven, are convenient to use, and produce delicious food. Combination steam ovens typically feature a hot air baffle on the rear panel of the inner pot. This baffle separates the inner pot into a cooking cavity and a hot air chamber. The hot air chamber houses a heating tube and a circulating fan. During cooking, the circulating fan rotates, and air in the cooking cavity enters the hot air chamber through the air inlet on the hot air baffle. The heating tube releases heat, and the air entering the hot air chamber is heated and then flows back into the cooking cavity through the air outlet on the hot air baffle, thereby heating the food placed in the cooking cavity.

[0003] The opening size of the air outlet on the existing hot air baffle is fixed. However, the shapes and volumes of ingredients are different, and the cooking modes are different, which have different requirements for air volume and temperature. Since heating tubes can be installed in multiple positions inside the cooking appliance, such as the top, bottom or rear, it is easy for the cooking cavity temperature to be uneven, which will have a negative impact on the cooking effect. Summary of the Invention

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a cooking utensil is provided, and the technical solution is as follows.

[0005] The cooking appliance includes an inner pot, a partition, a baffle, a first temperature sensor, a second temperature sensor and a controller. The inner pot is enclosed to form a accommodating space; the partition is connected to the inner pot and divides the accommodating space into a cooking space and an installation space, and an air outlet connecting the cooking space and the installation space is provided on the partition; the baffle is connected to a driving member, and the baffle is movable relative to the partition through the driving member to cover or open at least part of the air outlet; the first temperature sensor is used to detect a first temperature value of a first area in the cooking space; the second temperature sensor is used to detect a second temperature value of a second area in the cooking space; the controller controls the driving member to move the baffle based on the first temperature value and / or the second temperature value to change the size of the air outlet area of ​​the air outlet.

[0006] In the cooking appliance of the present invention, a controller causes a driving member to drive a baffle to move relative to an air outlet based on a temperature value in a cooking space detected by a temperature sensor, thereby changing the size of an air outlet area of ​​the air outlet. This can thereby adjust the air volume and temperature in the cooking space, thereby improving the uniformity of the temperature inside the cooking appliance and achieving a better cooking effect.

[0007] For example, the baffle includes a shielding portion and a connecting portion, wherein the shielding portion is connected to the connecting portion, the shielding portion at least partially abuts the partition, and the connecting portion is connected to the driving member. This arrangement not only satisfies the connection requirements between the baffle and the driving member, but also satisfies the requirements of shielding or opening the air outlet, thereby facilitating the adjustment of the air outlet area.

[0008] For example, a sliding limiter is provided on the partition, and the shielding part is limited in its movement direction by the sliding limiter. In this way, the sliding limiter ensures the stability of the shielding part's movement relative to the partition, thereby achieving at least partial opening or closing of the air outlet.

[0009] For example, the sliding stopper has an abutment end that stops the shielding portion in a first position. When the shielding portion is in the first position, the air outlet is closed. This arrangement can define the limit of movement of the shielding portion, thereby preventing excessive movement of the baffle and ensuring the stability of the connection between the connecting portion and the driving member.

[0010] For example, the inner pot has an upper plate, and the driving member is arranged on a side of the upper plate away from the cooking space. This arrangement not only saves installation space, but also keeps the driving member away from the air outlet, thereby preventing the driving member from being disturbed by the concentrated hot air.

[0011] For example, a through hole is provided on the upper plate of the bladder, and the connecting portion at least partially passes through the through hole to connect with the driving member. This arrangement facilitates the connection between the baffle and the driving member, ensuring that the baffle can be driven by the driving member to move, thereby changing the size of the air outlet area.

[0012] For example, the driver has a first tooth portion, and a second tooth portion is provided along the direction of movement of the baffle on the portion of the connection portion that passes through the through hole. The first tooth portion and the second tooth portion mesh with each other. This arrangement, through the cooperation of the first and second tooth portions, allows the controller to precisely control the driver to drive the baffle according to the temperature value, thereby changing the size of the air outlet area.

[0013] For example, an air inlet is provided in the middle of the partition, and the inner pot has an upper area and a lower area. The upper area is located above the air inlet. A first temperature sensor is provided in the upper area, while the lower area is located below the air inlet. A second temperature sensor is provided in the lower area. This arrangement detects the temperatures of the upper and lower areas of the inner pot, changes the air outlet area, and adjusts the hot air output volume to improve temperature uniformity within the cooking space, thereby achieving better cooking results.

[0014] According to another aspect of the present invention, a cooking temperature control method is provided for use with the aforementioned cooking appliance, comprising the following steps: detecting a first temperature value T1 in a first region of a cooking space using a first temperature sensor; detecting a second temperature value T2 in a second region of the cooking space using a second temperature sensor; and moving a baffle based on the first temperature value and / or the second temperature value to change the air outlet area. This arrangement not only ensures that the temperature in the cooking space reaches a preset temperature for cooking food, but also improves temperature uniformity within the cooking appliance, thereby achieving better cooking results.

[0015] For example, the step of moving the baffle based on the first temperature value T1 and / or the second temperature value T2 includes calculating T1 + T2 to obtain a temperature sum T3, subtracting the temperature sum T3 from twice the preset temperature T0, and comparing the result with a preset threshold. Based on the comparison result, the driving member is controlled to move the baffle to increase or decrease the air outlet area. This arrangement allows the total temperature within the cooking space to be detected and the air outlet area to be adjusted, thereby achieving a preset temperature within the cooking space for cooking food, thereby improving the cooking effect.

[0016] For example, the step of moving the baffle based on the first temperature value T1 and / or the second temperature value T2 includes controlling the driving member to move the baffle to increase or decrease the air outlet area of ​​the air outlet based on the difference between T1 and T2. This arrangement detects the temperatures of the upper and lower regions and adjusts the air outlet area accordingly, thereby improving temperature uniformity within the cooking space and achieving better cooking results.

[0017] This summary introduces a series of simplified concepts that will be further described in the detailed description. This summary is not intended to limit the key features and essential features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0030] In the following description, a large amount of detail is provided to facilitate a thorough understanding of the present invention. However, it will be appreciated by those skilled in the art that the following description merely illustrates preferred embodiments of the present invention, and that the present invention may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well known in the art have not been described in detail.

[0031] To provide a thorough understanding of the embodiments of the present invention, a detailed description of the structure will be provided in the following description. It should be understood that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of the present invention are described below in detail, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0032] One embodiment of the present invention provides a cooking appliance, which may be a variety of cooking appliances, including but not limited to a steamer, an oven, or a steam-bake combination appliance. The cooking appliance of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] See also Figure 1 、 Figure 2 and Figure 7 The cooking appliance may include an inner pot 110, a partition 120, a baffle 130, a first temperature sensor 141, a second temperature sensor 142, and a controller 150. The inner pot 110 may enclose a storage space. The partition 120 may be connected to the inner pot 110 and may separate the storage space into a cooking space 161 and an installation space 162. It is understood that the cooking space 161 may be used to place food for cooking. The partition 120 may be provided with an air outlet 121 connecting the cooking space 161 and the installation space 162. The baffle 130 may be connected to a driving member 170. The driving member 170 may be a motor, a cylinder, etc. The baffle 130 is movable relative to the partition 120 by the driving member 170 to cover or open at least a portion of the air outlet 121. The first temperature sensor 141 may be used to detect a first temperature value of a first area within the cooking space 161. The second temperature sensor 142 can be used to detect a second temperature value of a second area within the cooking space 161. Specifically, the controller 150 can be electrically connected to the first temperature sensor 141 and the second temperature sensor 142, and the controller 150 can also be electrically connected to the driver 170. The controller 150 can control the driver 170 to move the baffle 130 based on the first temperature value and / or the second temperature value to change the size of the air outlet area of ​​the air outlet 121.

[0034] In the cooking appliance of the present invention, the controller 150 detects the temperature value in the cooking space 161 based on the temperature sensor, so that the driving member 170 drives the baffle to move relative to the air outlet 121, thereby changing the size of the air outlet area of ​​the air outlet 121, thereby adjusting the air volume and temperature of the cooking space 161, improving the uniformity of the temperature inside the cooking appliance, and thus obtaining a better cooking effect.

[0035] Specifically, the number of air outlets 121 can be one or more. When there are multiple air outlets 121, the baffle 130 can simultaneously block or open at least part of the multiple air outlets 121. This not only saves costs but also saves space. The shape of the air outlet 121 can be square, circular, etc., and is not specifically limited here.

[0036] In some embodiments, the inner pot 110 may include a side panel 111. A first temperature sensor 141 may be connected to the upper portion of the inner side of the panel 111, and a second temperature sensor 142 may be connected to the lower portion of the inner side of the panel 111. This facilitates installation while also ensuring the accuracy of temperature detection by the first and second temperature sensors 141, 142. It should be understood that the installation locations of the first and second temperature sensors 141, 142 are not limited, as long as the first temperature sensor 141 can detect a first temperature value in the first area of ​​the cooking space 161 and the second temperature sensor 142 can detect a second temperature value in the second area of ​​the cooking space 161.

[0037] See also Figures 4 to 6 The baffle 130 may have a shielding portion 131 and a connecting portion 132. The shielding portion 131 may be connected to the connecting portion 132. The shielding portion 131 may be at least partially attached to the partition 120. The connecting portion 132 may be connected to the driving member 170. In this way, not only can the connection requirements of the baffle 130 and the driving member 170 be met, but also the requirements for blocking or opening the air outlet 121 can be met, and the size of the air outlet area of ​​the air outlet 121 can be conveniently changed. Specifically, the connecting portion 132 and the shielding portion 131 may be an integrated structure with a simple structure, which is easy to produce and manufacture, saving assembly time. Of course, the connecting portion 132 and the shielding portion 131 may also be a split structure, and the connecting portion 132 and the shielding portion 131 may be connected by screw connection or snap connection. When the connecting portion 132 or the shielding portion 131 is partially damaged, only the damaged connecting portion 132 or the shielding portion 131 can be replaced, reducing maintenance costs.

[0038] Furthermore, the connecting portion 132 may be bent and extended relative to the shielding portion 131 , thereby reducing contact between the connecting portion 132 and the partition 120 and avoiding friction between the connecting portion 132 and the partition 120 , thereby improving the efficiency of the movement of the baffle 130 .

[0039] See also Figure 1 and Figure 4 , a sliding limiter 122 may be provided on the partition 120. The shielding portion 131 may limit the moving direction (eg Figure 4XX direction). In this way, by providing the sliding limit portion 122, the stability of the movement of the shielding portion 131 relative to the partition 120 is ensured, so as to realize opening or closing of at least part of the air outlet 121. Specifically, the sliding limit portion 122 can be provided at both side ends of the shielding portion 131, and the shielding portion 131 moves along the sliding limit portion 122, further improving the stability of the movement of the shielding portion 131. The sliding limit portion 122 and the partition 120 can be an integrated structure, and the sliding limit portion 122 can be a plate-like member extending from the partition 120, which has a simple structure and saves assembly time. The sliding limit portion 122 and the partition 120 can also be a split structure, connected by screw connection or snap connection, etc., to facilitate maintenance or replacement.

[0040] Furthermore, the sliding limit portion 122 may have a slide rail 1221 , and the shielding portion 131 is sandwiched between the slide rail 1221 and the partition 120 , and the shielding portion 131 may move along the slide rail 1221 , thereby improving the efficiency of the movement of the baffle 130 .

[0041] Again, refer to Figure 1 and Figure 4 The sliding stopper 122 may include an abutment end 1222 that stops the shielding portion 131 in the first position. This abutment end 1222 may be the portion where the sliding stopper 122 connects to the partition 120, preventing the shielding portion 131 from further movement in the moving direction. When the shielding portion 131 is in the first position, it closes the air outlet 121. This limits the movement of the shielding portion 131, preventing excessive movement of the baffle 130 and ensuring the stability of the connection between the connecting portion 132 and the driver 170.

[0042] See also Figure 1 and Figure 2 The inner pot 110 may have a pot upper plate 112. The driving member 170 may be arranged on the side of the pot upper plate 112 away from the cooking space 161. This not only saves the installation space 162, but also keeps the driving member 170 away from the air outlet 121, thereby preventing the driving member 170 from being disturbed by the concentrated hot air. Specifically, a plate body 180 may be connected to the side of the pot upper plate 112 away from the cooking space 161. The plate body 180 and the pot upper plate 112 may be enclosed to form an air outlet duct 190, which is used to discharge steam and hot air to the outside to improve the cooking effect. The driving member 170 can be fixed on the side of the plate body 180 away from the air outlet duct 190 by a plate-like member. The plate-like member and the plate body 180 can be connected by fasteners such as screws or bolts, which not only ensures the firmness of the driving member 170 on the plate body 180, but also avoids the direct connection between the driving member 170 and the plate body 180, which makes processing difficult or causes the driving member 170 to be easily damaged.

[0043] Again, refer to Figure 1and Figure 4 The upper plate 112 of the air duct can be provided with a through hole 1121, through which at least a portion of the connecting portion 132 can pass to connect with the driving member 170. It is understood that the size of the through hole 1121 is greater than or equal to that of the connecting portion 132, so that the connecting portion 132 can pass through. This facilitates the connection between the baffle 130 and the driving member 170, ensuring that the baffle 130 can be driven by the driving member 170 to move, thereby changing the size of the air outlet area of ​​the air outlet 121.

[0044] See also Figure 4 and Figure 5 , the driving member 170 may have a first tooth portion 171. The portion of the connecting portion 132 passing through the through hole 1121 may be provided with a second tooth portion 1321 along the moving direction of the baffle 130. The first tooth portion 171 and the second tooth portion 1321 may be engaged with each other. Specifically, the first tooth portion 171 may be a gear, and the second tooth portion 1321 may be a rack, through which the gear of the driving member 170 is engaged with the rack of the connecting portion 132 to convert the rotational motion of the driving member 170 into the linear motion of the baffle 130. In this way, through the cooperation of the first tooth portion 171 and the second tooth portion 1321, the controller 150 can accurately control the driving member 170 to drive the baffle 130 according to the temperature value, thereby changing the size of the air outlet area of ​​the air outlet 121.

[0045] In some embodiments, the movement range of the baffle 130 is greater than or equal to the length or width of the air outlet 121 , so that the driving member 170 can drive the baffle 130 to completely cover or open the air outlet 121 .

[0046] See also Figure 2 and Figure 3 , an air inlet 123 may be provided in the middle of the partition 120. The inner pot 110 may have an upper area and a lower area. The upper area may be located above the air inlet 123. The first temperature sensor 141 may be provided in the upper area. The lower area may be located below the air inlet 123. The second temperature sensor 142 may be provided in the lower area. It is understandable that the upper area may be the first area, and the lower area may be the second area. In this way, by detecting the temperature of the upper and lower areas of the inner pot 110, the air outlet area of ​​the air outlet 121 is changed, and the air outlet volume of the hot air is adjusted to improve the temperature uniformity in the cooking space 161, thereby obtaining a better cooking effect.

[0047] In some embodiments, a fan and a heating pipe can be provided in the installation space 162 to heat the cooking space 161 from the back. When the fan rotates, the gas in the cooking space 161 can enter the installation space 162 through the air inlet 123. The heating pipe releases heat energy, heating the gas entering the installation space 162. The heated gas (i.e., hot air) can flow back into the cooking space 161 through the air outlet 121. The upper plate 112 can also be provided with a heating pipe to heat the cooking space 161 from the top. The inner pot 110 can have a lower plate (not shown in the figure), which can also be provided with a heating pipe to heat the cooking space 161 from the bottom.

[0048] There can be multiple air outlets 121. A portion of the multiple air outlets 121 can be located at the upper portion of the partition 120, that is, above the air inlet 123. Another portion of the first air outlet 121 can be located at the lower portion of the partition 120, that is, below the air inlet 123. The baffle 130 can block or open the air inlet 123 located at the upper portion. The multiple air outlets 121 at the upper portion can be grouped into at least five air outlets 121, and there can be at least two groups, and each two groups can be arranged at intervals. The length of the portion of the baffle 130 relative to the interval position of each two groups of air outlets 121 along the moving direction can be smaller than the length of the portion of the baffle 130 relative to the position of the air outlet 121 along the moving direction, so as to save costs, save installation space 162, reduce friction between the partition 120 and the baffle 130, and improve the efficiency of the movement of the baffle 130.

[0049] The cooking appliance can have at least two cooking modes. For example, for cooking spaces 161 that perform upper and lower heating, when the temperature in the upper area is too high, the baffle 130 can increase the outlet area of ​​the upper air outlet 121 to accelerate air circulation, allowing the air heated by the upper heating tube to flow to the outside along the air outlet duct 190, thereby lowering the temperature in the upper area of ​​the cooking space 161. Conversely, when the temperature in the upper area is too low, the baffle 130 can decrease the outlet area of ​​the upper air outlet 121 to slow air circulation, allowing the air heated by the upper heating tube to remain, thereby raising the temperature in the upper area of ​​the cooking space 161. This maintains a uniform temperature within the cooking space 161. Take the cooking mode of back heating in the cooking space 161 as an example; when the temperature of the upper area is too high, the baffle 130 can reduce the air outlet area of ​​the upper air outlet 121 to reduce the hot air entering the cooking space 161 from the air outlet 121, thereby lowering the temperature of the upper area of ​​the cooking space 161; conversely, when the temperature of the upper area is too low, the baffle 130 can increase the air outlet area of ​​the upper air outlet 121 to increase the hot air entering the cooking space 161 from the air outlet 121, thereby raising the temperature of the upper area of ​​the cooking space 161; in this way, the temperature in the cooking space 161 is kept uniform.

[0050] According to another aspect of the present invention, a cooking temperature control method is provided for use with the aforementioned cooking appliance, comprising the following steps: detecting a first temperature value T1 in a first area within a cooking space 161 using a first temperature sensor 141. Detecting a second temperature value T2 in a second area within the cooking space 161 using a second temperature sensor 142. Based on the first temperature value and / or the second temperature value, the baffle 130 is moved to change the air outlet area of ​​the air outlet 121. This method not only ensures that the temperature within the cooking space 161 reaches a preset temperature for cooking food, but also improves temperature uniformity within the cooking appliance, thereby achieving better cooking results.

[0051] For example, the step of moving baffle 130 based on first temperature value T1 and / or second temperature value T2 includes calculating T1 + T2 to obtain a temperature sum T3, subtracting the temperature sum T3 from twice the preset temperature T0, and comparing the result with a preset threshold. Based on the comparison result, driving member 170 is controlled to move baffle 130 to increase or decrease the air outlet area of ​​air outlet 121. In this way, by detecting the total temperature within cooking space 161 and adjusting the air outlet area of ​​air outlet 121, the temperature within cooking space 161 reaches the preset temperature, thereby improving the cooking effect.

[0052] For example, the step of moving baffle 130 based on first temperature value T1 and / or second temperature value T2 includes controlling driver 170 to move baffle 130 based on the difference between T1 and T2 to increase or decrease the air outlet area of ​​air outlet 121. In this way, by detecting the temperatures of the upper and lower regions and adjusting the air outlet area of ​​air outlet 121 accordingly, the temperature uniformity within cooking space 161 is improved, thereby achieving a better cooking effect.

[0053] In summary, see Figure 8 The cooking temperature control method is described in detail below. Taking the upper heating and lower heating cooking modes as an example, the default initial position of the baffle 130 is between fully open and fully closed (i.e., the position when the temperature inside the inner pot 110 is uniform). The preset threshold value can be -4, -5, or -6 (the preset threshold value of -5 is used as an example below);

[0054] S1. Select cooking mode and set the working time t0 and temperature T0 of the cooking appliance;

[0055] S2. After the cooking appliance is started, the first temperature sensor 141 detects a first temperature value T1 of the upper area of ​​the cooking space 161 and transmits the temperature value to the controller 150. The second temperature sensor 142 detects a second temperature value T2 of the lower area of ​​the cooking space 161 and transmits the temperature value to the controller 150.

[0056] S3, the controller 150 calculates T1+T2 to obtain the temperature of the inner tank 110 and T3, and calculates T3-2T0 and compares it with the preset threshold value -5;

[0057] S4. When the controller 150 determines that T3-2T0 is less than or equal to -5, the controller 150 controls the driving member 170 to drive the baffle 130 to move to fully open the air outlet 121 in the upper area;

[0058] S5. When the controller 150 determines that T3-2T0 is greater than -5, the controller 150 calculates T1-T2 and compares it with 0;

[0059] S6. When the controller 150 determines that T1-T2 is equal to 0, the baffle 130 remains at the initial position;

[0060] S7. When the controller 150 determines that T1-T2 is greater than 0, the controller 150 controls the driving member 170 to drive the baffle 130 to move until the upper air outlet 121 is fully opened;

[0061] S8. When the controller 150 determines that T1-T2 is less than 0, the controller 150 controls the driving member 170 to drive the baffle 130 to move until the upper air outlet 121 is completely closed;

[0062] S9: When the set working time t0 of the cooking appliance is reached, the cooking appliance stops working.
