Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a cooking device. Background Art

[0002] Cooking equipment such as steam ovens and baking ovens generate cooking fluids such as high-temperature gas or steam mist for cooking food during operation, and blow the cooking fluids toward the food through the fluid blowing member to cook the food. Increasing the flow rate of the cooking fluid can speed up the cooking of the food and shorten the cooking time.

[0003] The traditional method of increasing the flow rate is to increase the power of the fluid blowing member, such as increasing the operating speed of the fluid blowing member. This method will shorten the life of the fluid blowing member, reduce the reliability of the cooking equipment, and significantly increase energy consumption. Replacing the high-power fluid blowing member will increase the cost of the cooking equipment.

[0004] For example, in some usage scenarios, the food only occupies a small volume space in the cooking device, and the power increase of the fluid blowing member increases the total amount of cooking fluid, while the total amount of cooking fluid required to bake the food is small, resulting in a considerable portion of the cooking fluid not being fully utilized and being wasted. Utility Model Content

[0005] In view of this, the utility model provides a cooking device which can accelerate the cooking of food and has higher reliability and durability and better power consumption performance.

[0006] The cooking device of the utility model comprises a furnace wall equipped with multiple groups of air valves, a furnace cavity and a fluid blowing member respectively arranged on both sides of the furnace wall, and a partition member dividing the furnace cavity into multiple sub-cavities, each sub-cavity is associated with and controlled by at least one group of air valves, when the air valve of any sub-cavity is opened, the associated sub-cavity is connected to the side of the furnace wall away from the furnace cavity, and when the air valve of any sub-cavity is closed, the associated sub-cavity is blocked from the side of the furnace wall away from the furnace cavity.

[0007] The cooking device of the present invention divides the internal space of the furnace cavity, and the volume of each sub-cavity is smaller than the total volume of the furnace cavity. After the user puts food into any one or several sub-cavities, the valves associated with these sub-cavities are opened, and the valves associated with the sub-cavities without food are closed. The fluid blowing member can blow and transport the cooking fluid to the sub-cavities containing food through the opened valves. Compared with the cooking fluid flowing in the entire furnace cavity, the cooking fluid can flow in the sub-cavities containing food at a higher flow rate, thereby accelerating the cooking process of the food in these sub-cavities. The cooking time can be shortened without increasing the power of the fluid blowing member, thereby avoiding the problems of reduced service life, reduced cooking reliability, increased energy consumption and increased costs due to the increased power of the fluid blowing member.

[0008] In one embodiment, the partition has an in-position state and a disengaged state. The partition divides the furnace cavity into at least two sub-cavities when in the in-position state, and merges the at least two sub-cavities when in the disengaged state.

[0009] With such a configuration, the user can configure the divider to be in place or out of place according to the shape and volume of the food, thereby flexibly configuring the volume space for accommodating the food in the oven cavity. The divider can be configured to be in place so that smaller food can be placed in the sub-cavity so that the food in the sub-cavity can be baked by hot air at a higher wind speed. The divider can also be configured to be out of place so that larger food can be placed in the cavity formed by the fusion of multiple sub-cavities.

[0010] In one embodiment, the partition includes a partition that is detachably connected to the furnace cavity. When in place, the partition is connected to the furnace cavity to form sub-cavities on both sides of the partition. When out of place, the partition is detached from the furnace cavity to merge the sub-cavities on both sides of the partition.

[0011] With this arrangement, the user can configure the in-place and out-of-place states of the partition by disassembling and assembling the partition. Whether dividing the furnace cavity into multiple sub-cavities or merging multiple sub-cavities into a larger cavity, it is easier to master and the operation is faster.

[0012] In one embodiment, the partition includes a food tray detachably connected to the oven cavity. When in place, the food tray is connected to the oven cavity so that upper and lower sides of the food tray form sub-cavities respectively.

[0013] With such arrangement, the food can be directly placed in the sub-cavity above the food tray, so that the food tray can be divided into sub-cavities and can also be directly used to support the food.

[0014] In one embodiment, the partition includes an airtight gate disposed between the plurality of sub-cavities. When in place, the airtight gate can close and airtightly isolate the plurality of sub-cavities, and can open to connect the plurality of sub-cavities.

[0015] With such a configuration, the airtight gate can eliminate the exchange of cooking fluids between the multiple sub-cavities by airtightly isolating the multiple sub-cavities, so that the cooking fluid in each sub-cavity can cook the food more efficiently. In addition, when different food ingredients are placed in the multiple sub-cavities respectively, the airtight gate can be used to block the gas exchange between the sub-cavities to avoid the food ingredients from tainting each other. When necessary, the multiple sub-cavities can be connected to allow the sub-cavities to exchange cooking fluids with each other.

[0016] In one embodiment, the partition comprises a partition detachably connected to the furnace cavity. In an out-of-position state, the partition is detached from the furnace cavity to merge the sub-cavities on both sides of the partition. In an in-position state, the partition is connected to the furnace cavity to form sub-cavities on both sides of the partition.

[0017] Each partition is associated with at least one set of airtight gates. When in place, the airtight gates can seal the gap between the partition and the inner wall of the furnace chamber to airtightly isolate multiple sub-cavities, and can open the gap between the partition and the inner wall of the furnace chamber to connect multiple sub-cavities.

[0018] With such an arrangement, the airtight gate can divide the furnace cavity together with the partition, and is also conducive to the reasonable arrangement of the position and posture of the partition in the furnace cavity. The shape and size of the airtight gate can be designed to be more compact, simple and easy to install in the furnace cavity, and the switching between multiple sub-cavities between the two states of airtight isolation and mutual connection is easier and more reliable, and the possibility of airtight gate failure is lower.

[0019] In one embodiment, there are multiple separators, each separator has an in-position state and a disengaged state, and each separator can be independently switched between the in-position state and the disengaged state.

[0020] With this arrangement, users can more flexibly configure the volume space for accommodating food ingredients in the oven cavity. Each sub-cavity can be configured to be integrated with other adjacent sub-cavities, or to be separated from other adjacent sub-cavities. There are more diverse ways to form sub-cavities and integrate multiple sub-cavities.

[0021] In one embodiment, each set of valves can be independently switched to an open state and a closed state.

[0022] With such a configuration, the cooking device is more convenient to use, allowing the user to place ingredients into any one or more sub-cavities, then open the valve associated with the sub-cavity containing the ingredients, and close the valve associated with the sub-cavity without ingredients, so that placing ingredients into the sub-cavity will not be restricted by the position of the sub-cavity.

[0023] In one embodiment, at least one group of air valves includes multiple air windows, and the connection and blocking state between the sub-cavity associated with any group of air valves and the side of the furnace wall facing away from the furnace cavity is controlled by the multiple air windows in the air valves, wherein each air window can be opened and closed independently.

[0024] Such a setting allows the user to more flexibly adjust the cooking efficiency and cooking time. After placing the food into the sub-cavity, the air windows in the valve associated with the sub-cavity can be flexibly adjusted, that is, the number of air windows in the valve that are in an open state can be changed, so that the amount of cooking fluid blown to the sub-cavity by the airflow blowing member can be adjusted. Changing the amount of cooking fluid blown to the sub-cavity can change the cooking time of the food in the sub-cavity, ultimately achieving fine-tuning control of the cooking time of each sub-cavity.

[0025] In one embodiment, the partition divides the furnace cavity along the depth direction of the furnace cavity, and forms a plurality of sub-cavities which are sequentially stacked along the depth direction of the furnace cavity.

[0026] With such arrangement, the user can put the food into the sub-cavity layer by layer along the depth direction of the oven cavity, which makes it more convenient to put the food in and prevents the food from being disturbed or damaged.

[0027] In one embodiment, multiple sub-cavities are stacked in sequence according to their respective height dimensions, and the height dimension of the sub-cavity is the dimension of the sub-cavity along the depth direction; or, the height dimensions of the multiple sub-cavities are the same, and the height dimension of the sub-cavity is the dimension of the sub-cavity along the depth direction.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0034] The utility model provides a cooking device 100 for cooking food by generating a cooking fluid. The cooking fluid may be high-temperature gas, steam mist, a mixture of high-temperature gas and steam mist, etc. The high-temperature gas is used to bake the food and make the food lose some moisture. The steam mist is used to steam the food and make the food retain some moisture. According to the type of the cooking fluid generated, the cooking device 100 may be a baking oven for generating high-temperature gas, a steaming oven for generating steam mist, or a cooking device 100 of other structural types such as a box type and a cabinet type for generating other cooking fluids.

[0035] The cooking device 100 of the utility model comprises a hollow box, a fluid blowing member 30 for blowing cooking fluid, and a partition 40 for dividing the inner space of the box. The box comprises a furnace wall 10 equipped with a plurality of air gates 11, and a furnace cavity 20 is formed on one side of the furnace wall 10. The fluid blowing member 30 is arranged on the other side of the furnace wall 10. The partition 40 is arranged in the furnace cavity 20, and the partition 40 divides the furnace cavity 20 into a plurality of sub-cavities 21. Figure 1-2 , Figure 1-2 The cooking device 100 shown is a baking oven, which bakes food by high-temperature gas. The fluid blowing member 30 in the baking oven is a hot air blower, which accelerates the high-temperature gas to form hot air.

[0036] In the present invention, any sub-cavity 21 is associated with a group of air valves 11, and any sub-cavity 21 is controlled by the air valves 11 associated with it. The control content of each group of air valves 11 on the sub-cavity 21 associated with it includes: the control and switching of the connection state and the blocking state of each sub-cavity 21 and the side of the furnace wall 10 away from the furnace cavity 20. The side of the furnace wall 10 away from the furnace cavity 20 is also the side where the fluid blowing member 30 is located. For the convenience of description, the side of the furnace wall 10 away from the furnace cavity 20 is referred to as the rear side of the furnace body, and the side of the furnace wall 10 close to the furnace cavity 20 is referred to as the front side of the furnace body.

[0037] Thus, the connection and blocking state between each sub-cavity 21 and the rear side of the furnace wall 10 is controlled by the air gate 11 associated with the sub-cavity 21. For any sub-cavity 21, when the air gate 11 associated with the sub-cavity 21 is opened, the sub-cavity 21 is connected to the rear side of the furnace wall 10, and when the air gate 11 associated with the sub-cavity 21 is closed, the sub-cavity 21 is blocked from the rear side of the furnace wall 10. The connection between the sub-cavity 21 and the rear side of the furnace wall 10 means that the cooking airflow can be accelerated by the fluid blowing member 30 and then blown into the sub-cavity 21 through the air gate 11 associated with the sub-cavity 21, so that the food in the sub-cavity 21 is cooked.

[0038] Since the partition 40 divides the oven cavity 20 inside the oven cavity 20 to form the sub-cavities 21, the volume of any sub-cavity 21 is smaller than the total volume of the oven cavity 20, and the total volume of the oven cavity 20 is substantially equal to the sum of the volumes of all the sub-cavities 21. Based on the verification of multiple experimental results, although the amount of cooking fluid that can be received by the sub-cavity 21 is smaller than the amount of cooking fluid that can be received by the oven cavity 20, according to the principle of fluid continuity, the flow rate of the cooking fluid when flowing in the sub-cavity 21 with a smaller volume is significantly greater than the flow rate of the cooking fluid when flowing in the entire oven cavity 20, and the increase in the flow rate of the cooking fluid has a significant contribution to accelerating the cooking of food and shortening the cooking time.

[0039] The following combination Figure 1 to Figure 3 The cooking device 100 of the present invention is introduced by taking a baking oven for generating high-temperature gas as an example.

[0040] In some embodiments, the cooking device 100 further includes a plurality of reflux channels (not shown), the number of the reflux channels being equal to the number of the sub-cavities 21, and the plurality of reflux channels being connected to the plurality of sub-cavities 21 in a one-to-one correspondence, one end of each reflux channel being connected to the sub-cavity 21 corresponding to itself, and the other end leading to the rear side of the furnace wall 10, so that each sub-cavity 21 can be connected to the rear side of the furnace wall 10 again through the reflux channel corresponding to itself, thereby establishing a closed-loop flow path for the circulation of high-temperature gas between the rear side of the furnace wall 10 and each sub-cavity 21, and the hot air formed by the high-temperature gas is blown away from the fluid blowing member 30 and enters the sub-cavity 21, and then flows out of the sub-cavity 21 and enters the reflux channel corresponding to the sub-cavity 21, and then returns to the rear side of the furnace wall 10 through the reflux channel, and then is heated again and circulated again.

[0041] In other embodiments, multiple reflux channels may be partially or fully merged, that is, the number of reflux channels may be less than the number of sub-cavities 21. When the number of reflux channels is less than the number of sub-cavities 21, multiple sub-cavities 21 are connected to the same reflux channel to form a closed-loop flow path with the rear side of the furnace wall 10.

[0042] In some embodiments, each group of valves 11 can be switched to an open state and a closed state independently and without being affected by other groups of valves 11. When the user puts food into any of the sub-cavities 21, the valve 11 associated with the sub-cavity 21 can be switched to an open state, so that the fluid blowing member 30 blows the hot air formed by the high-temperature gas acceleration into the sub-cavity 21. When the user selects the sub-cavity 21 for placing food, the user is not limited to the position of the selected sub-cavity 21 or the sequence of the selected sub-cavity 21 in all the sub-cavities 21.

[0043] In some embodiments, there are multiple separators 40, each of which has an in-position state and a disengaged state, and each separator 40 can be switched to the in-position state and the disengaged state independently and without being affected by other separators 40. When one of the separators 40 is switched to the in-position state, other separators 40 are not considered, and the separator 40 divides the furnace cavity 20 into two sub-cavities 21, and the two sub-cavities 21 formed are respectively located on both sides of the separator 40; similarly, the remaining separators 40 are not considered, when one of the separators 40 that was originally in the in-position state is switched to the disengaged state, the separator 40 leaves its original position, and the two sub-cavities 21 originally located on both sides of the separator 40 are no longer blocked and merged to form a complete cavity.

[0044] It is understandable that in other embodiments, the number of the partitions 40 may also be one. It is worth noting that when the number of the partitions 40 is one, the partition 40 divides the furnace cavity 20 into at most two sub-cavities 21 with fixed shapes, positions and volumes. When the number of the partitions 40 is multiple, the partitions 40 can divide the furnace cavity 20 in different ways and obtain sub-cavities 21 with different shapes, positions and volumes. In fact, it is not necessary for all the partitions 40 to be in place to form multiple sub-cavities 21. When some partitions 40 are in place and other partitions 40 are out of place, the partitions 40 in place can still divide the furnace cavity 20 into multiple sub-cavities 21, which will be explained in detail below.

[0045] by Figure 1-2 Taking the embodiment shown as an example, there are two partitions 40, and the two partitions 40 are arranged in the oven cavity 20 at intervals along the depth direction of the oven cavity 20. When the two partitions 40 are in place, the two partitions 40 divide the oven cavity 20 into three sub-cavities 21 which are sequentially stacked along the depth direction of the oven cavity 20. When the cooking device 100 is used daily, the depth direction of the oven cavity 20 is the vertical direction. It can be understood that in other embodiments, three or more partitions 40 can be arranged at intervals along the depth direction of the oven cavity 20 or at intervals along other directions; when there are two partitions 40, the two partitions 40 do not need to be arranged at intervals along the depth direction of the oven cavity 20; when there is only one partition 40, the two sub-cavities 21 on both sides of the partition 40 do not need to be stacked along the depth direction of the oven cavity 20.

[0046] See again Figure 1-2, the three partitions 40 are named as the first partition 40 and the second partition 40 in the vertical downward direction, and the three sub-cavities 21 are named as the first sub-cavity 21, the second sub-cavity 21 and the third sub-cavity 21 in sequence. The first partition 40 is located between the first sub-cavity 21 and the second sub-cavity 21, and the second partition 40 is located between the second sub-cavity 21 and the third sub-cavity 21. The user can switch the first partition 40 to the off-position state so that the first sub-cavity 21 and the second sub-cavity 21 are merged, and the two are still one sub-cavity 21 after fusion; or switch the second partition 40 to the off-position state so that the second sub-cavity 21 and the third sub-cavity 21 are merged, and the two are still one sub-cavity 21 after fusion.

[0047] Specifically, in some embodiments, when all the dividers 40 in the cooking device 100 are in place, the number of sub-cavities 21 divided by the dividers 40 into the oven cavity 20 reaches a maximum value. At this time, the height dimensions of each of the sub-cavities 21 are the same, and the height dimension of each sub-cavity 21 is the dimension of the sub-cavity 21 along the longitudinal direction of the oven cavity 20. Figure 1-2 In the illustrated embodiment, the height dimensions of the first sub-cavity 21, the second sub-cavity 21, and the third sub-cavity 21 are all the same. Of course, in other embodiments, when all the partitions 40 in the cooking device 100 are in place, the height dimensions of the plurality of sub-cavities 21 may also be different, for example, the plurality of sub-cavities 21 may be arranged in increasing order or decreasing order in a vertical downward direction according to their respective height dimensions.

[0048] In some embodiments, each partition 40 includes a partition 41 detachably connected to the furnace cavity 20 and an airtight gate 42 movably disposed in the furnace cavity 20, and in each partition 40, the partition 41 is associated with at least one set of airtight gates 42. When any partition 40 is in place, the partition 41 of the partition 40 is connected to the furnace cavity 20, thereby dividing the furnace cavity 20 to form at least two sub-cavities 21, and the two sub-cavities 21 formed are respectively located on both sides of the partition 41, and at least one set of airtight gates 42 associated with the partition 41 blocks the gap 43 between the partition 41 and the inner wall of the furnace cavity 20, thereby achieving airtight isolation of the two sub-cavities 21 on both sides of the partition 41 and preventing fluid exchange.

[0049] Figure 2-Figure 3In the illustrated embodiment, each partition 40 includes a partition 41 and an airtight gate 42 associated with the partition 41. A plurality of connecting parts are provided in the furnace chamber 20. These connecting parts are used to be detachably connected to the partition 41. The position and posture of each connecting part in the furnace chamber 20 are fixed, that is, the partition 41 is always connected to the same connecting part in the same position and posture. The partition 41 is connected to the furnace chamber 20, which means that the partition 41 is connected to one of the connecting parts. At this time, a gap 43 is formed between the partition 41 and the inner wall of the furnace chamber 20. Subsequently, the airtight gate 42 associated with the partition 41 moves relative to the inner wall of the furnace chamber 20 to block the gap 43.

[0050] Furthermore, when any of the partitions 40 that were originally in the in-position state is switched to the out-position state, the partition 40 is removed from the furnace cavity 20 and thus leaves its original position, so that the two sub-cavities 21 that were originally located on both sides of the partition 41 merge to form a new cavity. When the number of partitions 40 is one, the cavity formed by the fusion of the two sub-cavities 21 after the partition 41 is removed is the entire furnace cavity 20; when the number of partitions 40 is multiple (in the present utility model, the number of a certain structure is multiple, which includes the case where the number of the structure is two), the cavity formed by the fusion of the two sub-cavities 21 after the partition 41 is removed is still one sub-cavity 21.

[0051] Thus, the user removes the partition 41 to switch the partition 40 to which the partition 41 belongs to the out-of-position state, and first connects the partition 41 to the furnace chamber 20, and then uses the airtight gate 42 associated with the partition 41 to close the gap 43 between the partition 41 and the inner wall of the furnace chamber 20, so that the partition 41 and the partition 40 to which the airtight gate 42 belongs are switched to the in-position state. Of course, in other embodiments, the airtight gate 42 can also achieve airtight isolation between multiple sub-cavities 21 in other ways, for example, the airtight gate 42 is installed in the gap 43 between the partition 41 and the inner wall of the furnace chamber 20, and the airtight gate 42 itself is provided with a through hole with an adjustable opening size, and the gas exchange on both sides of the partition 41 is blocked by reducing the opening of the through hole.

[0052] The purpose of providing the airtight lock 42 is to prevent gas exchange between the multiple sub-cavities 21. For example, when a user puts different ingredients into the multiple sub-cavities 21 at the same time, these ingredients may have mixed flavors. By blocking the sub-cavities 21 with different ingredients with the airtight lock 42, the situation of mixed flavors between different ingredients can be eliminated. It is understood that in other embodiments, the airtight lock 42 can also be eliminated.

[0053] Optional, see Figure 1 to Figure 3In some embodiments, the partition 41 includes a food tray 411 detachably connected to the inner wall of the oven cavity 20. The food tray 411 can be used directly to hold food. When the cooking device 100 is used daily, the food tray 411 is approximately perpendicular to the depth direction of the oven cavity 20. The user can connect the food tray 411 to the oven cavity 20 in a horizontal or approximately horizontal posture so that sub-cavities 21 are formed above and below the food tray 411. Figure 1 to Figure 3 In the illustrated embodiment, the partitions 41 are all food trays 411 . On this basis, some of the food trays 411 may be replaced with other types of partitions 41 .

[0054] In some embodiments not shown in the figure, there are multiple dividers 40, some of which are arranged at intervals along the first direction in the oven cavity 20, and the other parts are arranged at intervals along the second direction in the oven cavity 20, so that the multiple dividers 40 divide the oven cavity 20 into at least two types of sub-cavities 21, and the arrangement direction of the first type of sub-cavity 21 is different from that of the second type of sub-cavity 21. In this way, the shape, size, volume and position of the sub-cavity 21 are more diversified, which is more convenient to meet the needs of accommodating food of different shapes and sizes.

[0055] As mentioned above, each sub-cavity 21 is associated with and controlled by at least one set of air gates 11. In other words, multiple sets of air gates 11 may be provided, and these air gates 11 are jointly responsible for controlling the connection and barrier control and switching between a sub-cavity 21 and the rear side of the furnace wall 10. Further, in some embodiments, at least one set of air gates 11 includes multiple air windows 111. Taking multiple air windows 111 of one set of air gates 11 as an example, the air gate 11 is associated with a sub-cavity 21, and these air windows 111 are jointly responsible for the connection and barrier switching between the sub-cavity 21 and the rear side of the furnace wall 10. Any one of these air windows 111 can be opened and closed independently. When the user puts food into the sub-cavity 21, these air windows 111 can be opened partially or completely. By changing the number of openings of these air windows 111, the amount of hot air entering the sub-cavity 21 can be changed.

[0056] See also Figure 1 and Figure 3 In the embodiment shown in the figure, the furnace wall 10 is equipped with three groups of air doors 11, each group of air doors 11 includes two air windows 111 that are opened and closed independently. When food is put into one of the sub-cavities 21, one of the air windows 111 in the air door 11 associated with the sub-cavity 21 can be opened to cook the food at a relatively slow cooking rate, or both of the air windows 111 in the air door 11 associated with the sub-cavity 21 can be opened to cook the food at a relatively fast cooking rate. In this way, the dynamic adjustment of the hot air volume delivered in each sub-cavity 21 is achieved.

[0057] Optional, see Figure 3 In some embodiments, the air window 111 includes a through hole opened in the furnace wall 10, and also includes a door panel movably connected to the furnace wall 10, and the door panel moves relative to the furnace wall 10 to open or cover the through hole. The airtight gate 42 is similar to the door panel, and the airtight gate 42 is also movably connected to the furnace wall 10. The movement of the door panel and the airtight gate 42 can be controlled by a motor drive or an electromagnetic drive.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection required by the present invention.
