Description

Technical Field

[0001] The utility model relates to a cooking device and an integrated stove, belonging to the technical field of kitchen appliances. Background Art

[0002] At present, in integrated stoves, cooking devices such as steamers and ovens are usually selected as lower machines and configured in the integrated stoves to improve the functional integration of the integrated stoves.

[0003] For this type of cooker, due to the limitation of the space below the integrated stove, the inner pot of the cooker is structurally wide on the left and right sides and narrow on the top and bottom. In the prior art, this type of cooker heats and cooks the food by forming an internal circulation of hot air in the inner pot, and the air outlet position of the hot air in the inner pot is usually set on one side of the inner pot. However, since the left and right sides of the inner pot are wider, the lateral discharge of hot air will cause a temperature difference on both sides of the inner pot, causing uneven heating of the food, thereby reducing the cooking quality. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a cooker and an integrated stove, which can avoid the situation where there is a temperature difference between the left and right sides of the cooker, and the cooker has a strong air output to ensure the heating intensity.

[0005] The utility model is realized through the following technical solutions.

[0006] A cooking device, comprising:

[0007] The inner pot is limited to a cooking cavity;

[0008] An air duct extends from one of the inner liner side portions to the inner liner rear portion, and an air inlet and an air outlet are formed on the inner liner side portion and the inner liner rear portion respectively;

[0009] An air inducer, used for guiding hot air to circulate in the cooking cavity and the air duct;

[0010] The heater is used to heat the hot air in the air duct.

[0011] As a further improvement of the present invention, the air duct includes an air inlet portion located at the side of the inner liner and having the air inlet, an air outlet portion located at the rear of the inner liner and having the air outlet, and a circulation portion located at the bending part between the side of the inner liner and the rear of the inner liner and connecting the air inlet portion and the air outlet portion.

[0012] As a further improvement of the present invention, the air inducer includes fan blades located at the air inlet portion and a driving motor located outside the inner tank and used for driving the fan blades.

[0013] As a further improvement of the present invention, the heater is disposed in the air inlet portion and arranged on the periphery of the fan blade.

[0014] As a further improvement of the present invention, the heater is configured as an electric heating tube and surrounds the periphery of the fan blade.

[0015] As a further improvement of the present invention, the air inlet includes a plurality of air inlet holes, and the plurality of air inlet holes are dispersedly arranged on the side of the inner pot and connect the cooking cavity and the air inlet portion.

[0016] As a further improvement of the present invention, the air inlet hole is arranged at a position on the side of the inner tank corresponding to the coverage range of the fan blades.

[0017] As a further improvement of the present invention, the air outlet includes a plurality of air outlet holes, and the plurality of air outlet holes are dispersedly arranged at the rear of the inner pot and connect the cooking cavity and the air outlet portion.

[0018] As a further improvement of the present invention, the rear portion of the inner pot has at least one water outlet corresponding to the bottom side of the air outlet, and the water outlet connects the air outlet and the cooking cavity.

[0019] As a further improvement of the utility model, the inner liner includes two inner liner side panels constituting the main structure of the inner liner, an inner liner bottom plate, an inner liner rear plate, an inner liner top plate, and an air inlet plate, a connecting plate, and an air outlet plate connected in sequence;

[0020] One of the inner liner side panels has an inner concave portion that is recessed outward, and the edge of the air inlet plate is connected to the inner concave portion, so that the space between the air inlet plate and the inner liner side panel forms an air inlet portion located on the side of the inner liner;

[0021] The edge of the air outlet plate is connected to the rear plate of the inner container, so that the space between the air outlet plate and the rear plate of the inner container forms an air outlet portion located at the rear of the inner container;

[0022] The two side edges of the connecting plate connect the inner liner side plate and the inner liner rear plate, so that the space between the connecting plate and the inner liner side plate and the inner liner rear plate forms a flow portion.

[0023] As a further improvement of the present invention, the air outlet plate and the connecting plate both have a horizontally arranged convex structure or concave structure for placing plates carrying food.

[0024] An integrated stove comprises the cooker, wherein the cooker is configured as a lower machine of the integrated stove.

[0025] Beneficial effects of the utility model:

[0026] 1. The hot air is discharged from the air outlet at the rear of the inner pot from the back to the front into the cooking cavity, and then enters the air inlet at the side of the inner pot to complete the internal circulation flow. Since the inner pot has the characteristics of wide sides in structure, combined with the hot air outlet from the right back to the front, the temperature in the inner pot can be kept balanced on both sides to avoid temperature difference on both sides;

[0027] 2. The space on both sides of the cooker is more full.

[0028] 3. The heater is arranged at the periphery of the fan blades. Under the action of the fan, the hot air in the cooking cavity is drawn into the air inlet portion through the air inlet, and then diffuses to the periphery of the fan blades. In the process of diffusion, it can be fully heated by the heater, thereby improving the heating efficiency of the heater for hot air and ensuring that the temperature of the discharged hot air meets the established cooking requirements;

[0029] 4. Setting the air inlet to multiple air inlet holes can, on the one hand, increase the actual air intake volume and thus improve the throughput of the air duct; on the other hand, setting multiple air inlet holes can also prevent some lighter ingredients from being sucked into the air inlet part under the action of the fan; setting the air outlet to multiple dispersed air outlet holes can make the hot air discharged evenly, so that the heating effect is uniform.

[0037] The utility model is further described in detail below based on the accompanying drawings and implementation cases.

[0038] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0039] Implementation Case 1:

[0040] A cooking device, referring to Figure 1-5 , including an inner pot 1, the inner pot 1 has an opening, and its internal space is defined as a cooking cavity r for cooking ingredients, and the inner pot 1 is provided with a door body at the opening for opening or closing the cooking cavity r. The inner pot 1 of this embodiment is roughly a square body structure, and has the structural characteristics of being wide at both sides and narrow at the top and bottom.

[0041] The cooking device of this embodiment also includes an air duct m, an air inducer and a heater 2. The air duct m extends from one of the inner pot side parts 1a of the inner pot 1 to the inner pot rear part 1b, and an air inlet a and an air outlet b are formed on the inner pot side part 1a and the inner pot rear part 1b respectively, and the cooking cavity r and the air duct m are connected through the air inlet a and the air outlet b. The air inducer is used to guide the hot air from the cooking cavity r into the air inlet a of the air duct m, and then flow along the air duct m and then flow back to the cooking cavity r from the air outlet b, that is, the hot air is guided to circulate in the cooking cavity r and the air duct m, realizing the internal circulation flow of the hot air in the cooker. The heater 2 is used to heat the hot air in the air duct m to increase the cooking temperature.

[0042] In the cooker of the present embodiment, hot air is discharged from the air outlet b located at the rear part 1b of the inner pot from the back to the front into the cooking cavity r, completing the air outlet, heating and cooking the objects in the inner pot 1, and then entering the air inlet a located at the side part 1a of the inner pot to complete the internal circulation flow. Since the inner pot 1 of the present embodiment has the structural characteristics of wide two sides, combined with the hot air outlet mode from the right rear to the front, the temperature in the inner pot 1 can be kept balanced on both sides, avoiding the problem of unbalanced heating caused by the temperature difference on both sides in the prior art, thereby improving the cooking quality of the cooker.

[0043] It should be noted that the cooker in this embodiment is mainly used in an integrated stove. More specifically, the cooker is configured as a lower machine of the integrated stove. However, due to the space limitation at the bottom of the integrated stove, the space on both sides of the cooker is more full than the narrow space at the top of the cooker. Therefore, in this embodiment, a part of the air duct m is set on the side 1a of the inner tank to occupy more space than the top, which can increase the throughput of the air duct m, so that the cooker can have a stronger air output to ensure the heating and cooking intensity of the ingredients.

[0044] In this embodiment, the specific structure of the air duct m is as follows: the air duct m includes an air inlet m1, an air outlet m3 and a circulation part m2, wherein the air inlet m1 is located at the side of the inner pot 1a and has an air inlet a, the air outlet m3 is located at the rear of the inner pot 1b and has an air outlet b, and the circulation part m2 is located at the bend of the side of the inner pot 1a and the rear of the inner pot 1b, and connects the air inlet m1 and the air outlet m3, and the hot air flows laterally and enters the air inlet m1 from the air inlet a, then flows along the circulation part m2 to the air outlet m3, and then is discharged from the air outlet b from the back to the front into the cooking cavity r to complete the cycle. The specific structure of the air duct m is configured as the shortest path from the air inlet a to the air outlet b, so that the flow distance of the hot air in the air duct m is minimized, thereby improving the internal circulation efficiency of the hot air.

[0045] In this embodiment, the air inducer includes a fan blade 31 and a drive motor 32 for driving the fan blade 31, wherein the fan blade 31 is arranged in the air inlet m1, and the drive motor 32 is arranged outside the inner liner 1. When the air inlet m1 is provided with sufficient space, the fan blade 31 is selected to be of a relatively large size and adapted to the size of the air inlet m1, and the drive motor 32 is also configured to be a power-matching model.

[0046] Under ideal conditions, it is the best solution to set the heater 2 in the air duct m, because the heater 2 will not occupy the space of the cooking cavity r, which is conducive to placing food in the cooking cavity r. Based on this, in this embodiment, the heater 2 is set in the air inlet m1 and arranged on the periphery of the fan blade 31. Under the action of the fan, the hot air in the cooking cavity r is drawn into the air inlet m1 through the air inlet a, and then diffuses to the periphery of the fan blade 31 and then flows into the circulation part m2. The hot air can be fully heated by the heater 2 during the diffusion process, thereby improving the heating efficiency of the heater 2 for the hot air and ensuring that the temperature of the discharged hot air meets the established cooking requirements.

[0047] In this embodiment, the heater 2 is set as an electric heating tube. On the one hand, due to the fast response speed and small thermal inertia of electric heating, precise temperature control can be achieved, which is particularly suitable for cooking heating tasks of the cooker. On the other hand, the electric heating tube is relatively compact in structure, easy to install in the air inlet m1 and occupies a small space. More specifically, the electric heating tube is annular in structure and arranged around the fan blades 31. The number of turns of the electric heating tube can be increased to improve the heating intensity of the hot air. In addition, a clamp 21 is set to bind and fix the electric heating tube to prevent the fan blades 31 from scratching the electric heating tube when starting and causing damage.

[0048] In the present embodiment, for the air inlet a, the air inlet a includes a plurality of air inlet holes a1, and the plurality of air inlet holes a1 are dispersedly arranged on the side portion 1a of the inner pot, and the air inlet holes a1 connect the cooking cavity r and the air inlet portion m1. Since the setting space of the air inlet portion m1 is relatively full, the air inlet a is set as a plurality of air inlet holes a1. On the one hand, the actual air intake volume can be increased, thereby improving the throughput of the air duct m. On the other hand, setting a plurality of air inlet holes a1 can also prevent some lighter ingredients from being sucked into the air inlet portion m1 under the action of the fan.

[0049] In this embodiment, the position of the air inlet a1 arranged on the side portion 1a of the inner liner corresponds to the coverage range of the fan blades 31. The correspondence between the air inlet a1 and the coverage range of the fan blades 31 can improve the air intake efficiency of the air inlet a1, thereby improving the overall efficiency of the internal circulation in the inner liner 1.

[0050] In this embodiment, the air outlet b includes a plurality of air outlet holes b1, which are dispersedly arranged at the rear portion 1b of the inner pot, and are preferably evenly arranged. The air outlet holes b1 connect the cooking cavity r and the air outlet portion m3, so that the hot air can be evenly discharged forward from the rear portion 1b of the inner pot, thereby making the heating effect of the hot air on the food more uniform and improving the cooking quality.

[0051] In addition, in this embodiment, the rear portion 1b of the inner pot has at least one water outlet b2 at the bottom side corresponding to the air outlet m3, and the water outlet b2 connects the air outlet m3 and the cooking cavity r. When the hot air circulates, the condensed water generated in the air duct m will flow downward in the air outlet m3 and be discharged from the water outlet b2. Generally, one or two water outlets b2 can meet the needs.

[0052] As for the specific structural composition of the inner liner 1, in the present embodiment, the inner liner 1 includes two inner liner side panels 11, an inner liner bottom panel 12, an inner liner rear panel 14, an inner liner top panel 13, an air inlet panel 15, a connecting panel 16 and an air outlet panel 17, wherein the two inner liner side panels 11, the inner liner rear panel 14, the inner liner bottom panel 12 and the inner liner top panel 13 constitute the main structure of the inner liner 1 having an opening.

[0053] One of the inner liner side panels 11, i.e., the inner liner side panel 11 corresponding to the air inlet portion m1, has an inner recess 111 that is recessed outward, and the edge of the air inlet plate 15 is connected to the inner recess 111, so that the space between the air inlet plate 15 and the inner recess 111 forms the air inlet portion m1 located at the inner liner side portion 1a, the air inlet a is arranged on the air inlet plate 15, the fan blade 31 is arranged in the space between the inner recess 111 and the air inlet plate 15, the driving motor 32 is installed on the outer wall of the inner recess 111, and its starting shaft passes through the inner recess 111 and is connected to the fan blade 31; The air plate 17 has a folded edge 171 at its edge and is connected to the inner liner rear plate 14, so that the space between the air outlet plate 17 and the inner liner rear plate 14 forms an air outlet portion m3 located at the inner liner rear portion 1b, and the air outlet b is arranged on the air outlet plate 17; the connecting plate 16 is arranged obliquely and connects the rear edge of the air inlet plate 15 and the top edge of the air outlet plate 17, and the two side edges 161 of the connecting plate 16 are bent and connected to the inner liner side panel 11 and the inner liner rear plate 14, so that the space between the connecting plate 16 and the inner liner top plate 13 and the inner liner rear plate 14 forms a flow portion m2.

[0054] In this embodiment, the inner wall of the air outlet plate 17 has a plurality of horizontally arranged convex structures j, and the inner wall of the connecting plate 16 has a plurality of horizontally arranged concave structures k, and the convex structures j and the concave structures k are used to place plates carrying food. Obviously, the concave structures k can also be provided on the air outlet plate 17, and the convex structures j can be provided on the connecting plate 16.
