The present disclosure generally relates to an oven, and more specifically, to a baffle assembly for the oven that creates distinct air flow regions within a cooking chamber of the oven having different temperatures.
A user sometimes utilizes an oven to cook a food item or more than one food items for a meal. However, there are several problems. First, an oven preheats an entire volume of a cooking chamber regardless of a percentage of the volume the food item to be heated in the cooking chamber occupies. So preheating the oven results in an inefficient use of energy and time when the volume of the food item to be heated in the cooking chamber is relatively small compared to the volume of the cooking chamber that is preheated.
Second, the user cannot typically cook more than one food item simultaneously, because each food item typically requires a different temperature at which to be cooked. Rather, the user must typically cook a first food item in the oven at a first temperature, remove the first food item, wait for the cooking chamber to settle at a second temperature at which the second food item is to be cooked, and then cook the second food item at that second temperature. This problem again results in an inefficient use of energy and time because the food items have to be cooked consecutively rather than simultaneously.
According to one aspect of the present disclosure, an oven comprises: (a) interior walls forming a cooking chamber and providing an opening into the cooking chamber; (b) a baffle assembly comprising: (i) a top inlet positioned to draw air from the cooking chamber, (ii) a pair of top outlets, positioned laterally away from the top inlet, with one of the pair of top outlets positioned on one side of the baffle assembly and the other of the pair of top outlets positioned on another side of the baffle assembly, the pair of top outlets positioned to return air to the cooking chamber, (iii) top air flow paths from the top inlet to the pair of top outlets, (iv) a top wall that defines a top of each of the pair of top outlets and a top surface of the top air flow paths, (v) a bottom inlet positioned to draw air from the cooking chamber, (vi) a pair of bottom outlets, positioned laterally away from the bottom inlet, with one of the pair of bottom outlets positioned on the one side of the baffle assembly and the other of the pair of top outlets positioned on the other side of the baffle assembly, the pair of bottom outlets positioned to return air to the cooking chamber, (vii) bottom air flow paths from the bottom inlet to the pair of bottom outlets, and (viii) a bottom wall that defines a bottom of each of the pair of bottom outlets and a bottom surface of the bottom air flow paths; (c) a top fan positioned to force air to flow from the cooking chamber, through the top inlet, through the top air flow paths, and then back into the cooking chamber; (d) a top heating element positioned to heat air flowing through the top air flow paths; (e) a bottom fan positioned to force air to flow from the cooking chamber, through the bottom inlet, through the bottom air flow paths, and then back into the cooking chamber; and (f) a bottom heating element positioned to heat air flowing through the bottom air flow paths.

In embodiments, the top heating element 160 is further disposed between the axis of rotation 156 of the top fan 154 and the middle wall 144 of the baffle assembly 46. Accordingly, regardless of whether the air flowing through the top air flow paths 146a, 146b flows from the top inlet 56 to the top outlet 66a on the one side 68 of the baffle assembly 46 (i.e., top air flow path 146a) or to the top outlet 66b on the other side 70 of the baffle assembly 46 (i.e., top air flow path 146b), the top heating element 160 is able to increase or maintain the temperature of the air returning through the pair of top outlets 66a, 66b to the cooking chamber 12.
The baffle assembly 46 further includes bottom air flow paths 162a, 162b (see
The forward wall 58, the bottom wall 108, the middle wall 144, the rear wall 138, the first lateral vertical wall 82, and the second lateral vertical wall 84 of the baffle assembly 46 guide the air that enters the bottom inlet 62 from the cooking chamber 12 to the pair of bottom outlets 102a, 102b. The forward wall 58 defines a forward surface 164 of the bottom air flow paths 162a, 162b. The bottom wall 108 defines a bottom surface 166 of the bottom air flow paths 162a, 162b. The middle wall 144 defines a top surface 168 of the bottom air flow paths 162a, 162b, and the top surface 168 opposes the bottom surface 166. In embodiments, the top surface 168 and the bottom surface 166 of the bottom air flow paths 162a, 162b are generally horizontal. In embodiments, the forward surface 164 of the bottom air flow paths 162a, 162b is generally vertical.
The oven 10 further includes a bottom fan 170. The bottom fan 170 is positioned to force air to flow from the cooking chamber 12, through the bottom inlet 62, through the bottom air flow paths 162a, 162b, through the pair of bottom outlets 102a, 102b, and then back into the cooking chamber 12. For example, in embodiments, the bottom fan 170 is disposed rearward of the forward wall 58 of the baffle assembly 46, such as between the rear wall 138 and the forward wall 58 of the baffle assembly 46. The bottom fan 170 is disposed between the middle wall 144 and the bottom wall 108 of the baffle assembly 46. In embodiments, the bottom fan 170 has an axis of rotation 172 (see
In embodiments, the direction 158 in which the top fan 154 spins is opposite of the direction 174 in which the bottom fan 170 spins. For example, in embodiments, the top fan 154 spins counterclockwise, while the bottom fan 170 spins clockwise. As another example, in embodiments, the top fan 154 spins clockwise, while the bottom fan 170 spins counterclockwise. In embodiments, the direction 158 in which the top fan 154 spins is the same as the direction 174 in which the bottom fan 170 spins (e.g., both spin clockwise).
The oven 10 further includes a bottom heating element 176. The bottom heating element 176 is positioned to heat air flowing through the bottom air flow paths 162a, 162b. For example, in embodiments, the bottom heating element 176 is disposed rearward of the forward wall 58 of the baffle assembly 46, such as between the rear wall 138 and the forward wall 58 of the baffle assembly 46. The bottom heating element 176 is disposed between the middle wall 144 and the bottom wall 108 of the baffle assembly 46.

In embodiments, the bottom heating element 176 is further disposed between the axis of rotation 172 of the bottom fan 170 and the middle wall 144 of the baffle assembly 46. Accordingly, regardless of whether the air flowing through the bottom air flow paths 162a, 162b flows from the bottom inlet 62 to the bottom outlet 102a on the one side 68 of the baffle assembly 46 (i.e., the bottom air flow path 162a) or to the bottom outlet 102b on the other side 70 of the baffle assembly 46 (i.e., the bottom air flow path 162b), the bottom heating element 176 is able to increase or maintain the temperature of the air returning through the pair of bottom outlets 102a, 102b to the cooking chamber 12.
In embodiments, the baffle assembly 46 further includes a pair of middle outlets 178a, 178b. The middle outlet 178a is disposed at the one side 68 of the baffle assembly 46, between the top outlet 66a and the bottom outlet 102a that are disposed at that side 68 of the baffle assembly 46. The forward wall 58 and the first lateral vertical wall 82 cooperate to form the middle outlet 178a. The middle outlet 178a is disposed to overlap elevationally with the middle wall 144. In other words, the middle wall 144, if it were to extend through the first lateral vertical wall 82, would extend through the middle outlet 178a. The top tab 120 of the first lateral vertical wall 82 forms a top 180 of the middle outlet 178a. The forward wall 58 forms a forward portion 182 of the middle outlet 178a. The first lateral vertical wall 82 forms a rear portion 184 of the middle outlet 178a. The bottom tab 122 of the first lateral vertical wall 82 forms a bottom 186 of the middle outlet 178a. The middle outlet 178a is disposed between the top outlet 66a and the bottom outlet 102a at the first lateral vertical wall 82.
The middle outlet 178b is disposed at the other side 70 of the baffle assembly 46, between the top outlet 66b and the bottom outlet 102b that are disposed at that other side 70 of the baffle assembly 46. The forward wall 58 and the second lateral vertical wall 84 cooperate to form the middle outlet 178b. The middle outlet 178b is disposed to overlap elevationally with the middle wall 144. In other words, the middle wall 144, if it were to extend through the second lateral vertical wall 84, would extend through the middle outlet 178b. The top tab 126 of the second lateral vertical wall 84 forms a top 188 of the middle outlet 178b. The forward wall 58 forms a forward portion 190 of the middle outlet 178b. The second lateral vertical wall 84 forms a rear portion 192 of the middle outlet 178b. The bottom tab 128 of the second lateral vertical wall 84 forms a bottom 194 of the middle outlet 178b. The middle outlet 178b is disposed between the top outlet 66b and the bottom outlet 102b at the second lateral vertical wall 84.
In embodiments, the baffle outlet further includes a pair of doors—a first door 196 disposed at the one side 68 of baffle assembly 46 and a second door 198 disposed at the other side 70 of the baffle assembly 46. The first door 196 has a closed position 200 and an open position 202 (see
In the open position 202, the middle outlet 178a is open and access is allowed through the middle outlet 178a disposed at the first lateral vertical wall 82. Thus, air flowing through the top air flow path 146a toward the top outlet 66a and through the bottom air flow path 162a toward the bottom outlet 102a at the one side 68 of the baffle assembly 46 also flows through the middle outlet 178a.
The second door 198 is has a closed position 204 and an open position 206 (see
In the open position 206, the middle outlet 178b is open and access is allowed through the middle outlet 178b disposed at the second lateral vertical wall 84. Thus, air flowing through the top air flow path 146b toward the top outlet 66b and through the bottom air flow path 162b toward the bottom outlet 102b at the other side 70 of the baffle assembly 46 also flows through the middle outlet 178b.
In use, in instances when the food item 18 that the user desires to cook with the oven 10 occupies a significant portion of the cooking chamber 12, the user can place the first door 196 and the second door 198 of the baffle assembly 46 to their respective open positions 202, 206 to allow air to flow through all of the top outlets 66a, 66b, middle outlets 178a, 178b, and bottom outlets 102a, 102b of the baffle assembly 46. The top heating element 160 and the bottom heating element 176 can be set to heat air flowing through the baffle assembly 46 from the cooking chamber 12 to the same or approximately the same temperature. Thus, the entirety of the volume of the cooking chamber 12 achieves approximately the same temperature.
However, in instances where the user desired to cook two food items 18 with the oven 10, with each food item 18 at a different temperature (e.g., one food item 18 at a higher temperature, the other food item 18 at a lower temperature), the user can place the first door 196 and the second door 198 of the baffle assembly 46 in their respective closed positions 200, 204. In addition, the user places the food item 18 desired to be cooked at the higher temperature within the cooking chamber 12 elevationally above the food item 18 desired to be cooked at the lower temperature.
Air from the cooking chamber 12 will thus flow through the top air flow paths 146a, 146b to be heated by the top heating element 160 and separately through the bottom air flow paths 162a, 162b to be heated by the bottom heating element 176. The top heating element 160 is set to heat the air flowing through the top air flow paths 146a, 146b to a temperature that is greater than a temperature at which the bottom heating element 176 is set to heat the air flowing through the bottom air flow paths 162a, 162b.
Referring now to
In embodiments, the top region 48 of air flow 52 has a temperature that is at least 20° C. greater than a temperature of the bottom region 50 of air flow 52. For example, air flow 52 within the cooking chamber 12 at a top horizontal plane 208 (see
Because the baffle assembly 46 is able to generate the top region 48 and the bottom region 50 of air flow 52 having different temperatures, the user can simultaneously cook two food items 18. For example, the user can steam pasta within the top region 48 of the cooking chamber 12 at 100° C. simultaneously with reheating a prior meal within the bottom region 50 of the cooking chamber 12 at 65° C. As another example, the user can cook a rice casserole at 180° C. within the top region 48 of the cooking chamber 12 simultaneously with baking a shortbread cake at 170° C. within the bottom region 50 of the cooking chamber 12. As another example, the user can cook a meat loaf at 230° C. within the top region 48 of the cooking chamber 12 simultaneously with baking potatoes at 200° C. within the bottom region 50 of the cooking chamber 12. Thus, the present disclosure solves the problem of an oven not allowing the user to cook more than one food item 18 simultaneously at different temperatures.
Further, in instances where the user desires to cook a single food item 18 that is sized to fit within solely the top region 48, the baffle assembly 46 of the present disclosure allows the top region 48 to be heated to the desired temperature while the bottom region 50 can be heated to a lower temperature. The first door 196 and the second door 198 of the baffle assembly 46 are placed in their respective closed positions 200, 204. The oven 10 can be preheated so that the top region 48 is at the desired temperature to cook the single food item 18. The lower region, which will not be utilized to cook the single food item 18, can be preheated to a temperature that is less than the temperature of the top region 48. The entirety of the volume of the cooking chamber 12 does not need to be preheated to the temperature at which the single food item 18 will be cooked at the top region 48. The user then places the single food item 18 within the top region 48 for cooking. Thus, the present disclosure solves the problem of a typical oven requiring preheating of the entirety of the volume of the cooking chamber 12 to the desired temperature, and the associated inefficient use of energy and time that arises from doing so.
