Description

Technical Field

[0001] The invention relates to the technical field of steaming and baking cooking machines, in particular to an evaporation plate assembly and a steaming and baking cooking machine. Background Art

[0002] The steam-bake cooking machine can lock in the moisture of food during the steaming and baking process, thereby maintaining the fresh and tender taste of the food. Compared with an oven, it is more suitable for making low-fat and low-calorie food and is deeply favored by consumers.

[0003] At present, steam-bake cooking machines generally use a built-in evaporation plate to generate steam. This structure is simple and the path for steam to reach food is short. However, existing evaporation plates usually have a heating body directly at the bottom to heat water directly to boiling. In this process, the boiling water will bring up fine steam particles, resulting in high steam humidity, which seriously affects the taste of food. In addition, the contaminated water mixed with salt, sugar and oil dripping from the food will also make it difficult to clean the evaporation plate. Therefore, it is necessary to spray a coating on the inner surface of the evaporation plate to achieve an anti-stick effect, which undoubtedly affects the heat conduction capacity of the evaporation plate. Summary of the invention

[0004] Since the existing steam-bake cooking machine has the problems of poor cooking taste and difficulty in taking into account both the thermal energy utilization efficiency and anti-sticking effect of the evaporation plate, it is necessary to provide an evaporation plate assembly and a steam-bake cooking machine.

[0005] Evaporator assembly, comprising:

[0006] A heating plate, the heating plate having a water storage tank, for heating liquid in the water storage tank to form wet steam;

[0007] A diverter plate, the diverter plate is covered on the heating plate and has a plurality of air outlets connected to the water storage tank; and

[0008] A heating pipe is located in the water storage tank and close to the air outlet, and is used to heat the wet steam reaching the air outlet to form superheated steam.

[0009] Such an arrangement, by covering the heating plate and heating it with a heating tube, greatly reduces the contact between wet steam and food, ensures the dryness of the steam, ensures the taste of the food after steaming and baking, and is conducive to improving the user experience.

[0010] In one embodiment, the heating plate includes a plate body providing the water tank and a heating body arranged at the bottom of the plate body; the plate body is provided with a water inlet connected to the water tank, and the diverter plate is arranged on the top of the plate body to cover the notch of the water tank.

[0011] With such an arrangement, the opening of the water inlet makes it convenient to add evaporation water during the steaming and baking process. In addition, due to the introduction of the heating tube, the heating body can be used only for the evaporation of condensed water in the water tank, without having to heat the condensed water to generate steam for steaming and baking. Therefore, the heat transfer performance requirements of the plate body are relatively low. For the evaporating plate assembly of the present application, a double-layer or multi-layer cleaning coating can be provided on the inner surface of the plate body of the heating plate, which is beneficial to increase the cleanability of the heating plate.

[0012] In one embodiment, the evaporation disk assembly also includes a partition cylinder located in the water storage tank, and the partition cylinder includes a first cylinder body abutting against the bottom wall of the disk body and a stop ring plate radially extending from the outer peripheral wall of the first cylinder body to the inner peripheral wall of the disk body, so as to divide the water storage tank into a heating chamber connected to the air outlet and a buffer chamber connected to the water inlet. The first cylinder body is also provided with a first connecting hole for connecting the heating chamber and the buffer chamber, and the first connecting hole is located on the side of the first cylinder body away from the water inlet.

[0013] This arrangement lengthens the path for cold water to enter the heating chamber, preventing cold water from directly rushing into the heating chamber and causing steam generation to temporarily stop.

[0014] In one embodiment, the separation cylinder also includes a separation plate located inside the first cylinder body to divide the heating chamber into a steam production space connected to the first connecting hole and a conversion space connected to the air outlet hole. The separation plate also has a plurality of steam channels connecting the steam production space and the conversion space. The heating pipe is located in the conversion space.

[0015] In this way, by setting a partition plate on the steam path, the wet steam in the steam production space will be fully vaporized by the heating tube and converted into superheated steam after entering the conversion space, which improves the dryness of the steam and increases the latent heat of the steam.

[0016] In one embodiment, the partition cylinder also includes a second cylinder extending from the partition plate toward the bottom wall of the disk body and spaced apart from the first cylinder to form an insulating space together with the first cylinder and the partition plate, and a plurality of second connecting holes are opened on one side of the second cylinder close to the bottom wall of the disk body.

[0017] Such an arrangement further increases the flow path of the cold flow, and there is an insulating space between the cold flow in the buffer cavity and the hot flow in the steam producing space, which can minimize the heat loss in the steam producing space and ensure that the addition of cold water will not cause the steam producing space to be temporarily unable to produce steam.

[0018] In one embodiment, a plurality of the second connecting holes are symmetrically arranged along a line connecting the water inlet and the first connecting hole.

[0019] With such arrangement, when the cold flow enters the steam production space chamber from different second connecting holes, the impact on the steam production space is more uniform, thus avoiding the situation where the temperature field in the steam production space is disturbed.

[0020] In one embodiment, the separation cylinder further includes a support ring plate extending from the first cylinder, wherein the support ring plate abuts against the bottom wall of the disk body in the axial direction and against the inner peripheral wall of the disk body in the radial direction.

[0021] Such an arrangement ensures the position stability of the separation cylinder in the heating plate and avoids the problem of the separation cylinder floating up due to the buoyancy in the insulation space.

[0022] In one embodiment, the diverter plate includes a central area recessed toward the heating disk and an edge area surrounding the central area.

[0023] Such an arrangement makes it convenient to collect dirt dripping from food, and makes it convenient for the user to directly take out and clean the partition plate.

[0024] In one embodiment, the diverter plate includes a plate body providing the central area and the edge area and a plurality of convex shells recessed from the central area of ​​the plate body in a direction away from the heating plate, the air outlet is located in the convex shell, and the vertical distance between the air outlet and the central area is greater than the recessed distance of the central area.

[0025] This arrangement minimizes the possibility of dirt entering the water tank, ensures the purity of the steam, and guarantees cooking quality.

[0026] Steam-bake cooking machine, comprising:

[0027] a liner body; and

[0028] As for the above-mentioned evaporation tray assembly, the evaporation tray assembly is installed on the inner tank body.

[0029] With such arrangement, the evaporation plate assembly provided by the present application is used, and the steam production efficiency is high, and the steam dryness is good, which is conducive to ensuring the cooking quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The steam-bake cooking machine can lock in the moisture of food during the steaming and baking process, thereby maintaining the fresh and tender taste of the food. Compared with an oven, it is more suitable for making low-fat and low-calorie food and is deeply favored by consumers.

[0045] At present, steam-bake cooking machines generally use a built-in evaporation plate to generate steam. This structure is simple and the path for steam to reach food is short. However, the existing evaporation plate usually directly sets a heating body 12 at the bottom to directly heat water to boil. In this process, the boiling water will bring up fine steam particles, resulting in high steam humidity, which seriously affects the taste of food; in addition, the contaminated water mixed with salt, sugar and oil dripping from the food will also make it difficult to clean the evaporation plate, so it is necessary to spray a coating on the inner surface of the evaporation plate to achieve an anti-sticking effect, which undoubtedly affects the heat conduction capacity of the evaporation plate.

[0046] Based on this, it is necessary to provide an evaporation plate assembly and a steam-bake cooking machine that can provide dry steam and have good heat conduction effect and do not require an anti-stick coating.

[0047] See also Figures 1 to 3 , Figure 1 This is a partial structural schematic diagram of a steaming and baking cooking machine according to an embodiment of the present invention. Figure 2 for Figure 1 Structural diagram of the middle steaming and baking tray assembly. Figure 3 for Figure 2 The cross-sectional view of the steam-bake pan assembly is shown. The steam-bake cooking machine provided by the present application includes an inner tank body 50 and an evaporation pan assembly installed at the bottom of the inner tank body 50, and a sealing gasket 60 is provided between the evaporation pan assembly and the inner tank body 50. The steam-bake pan assembly provided by the present application includes a heating pan 10, a diverter plate 20 and a heating tube 30. The heating pan 10 has a water storage tank 101 and is used to heat the liquid in the water storage tank 101 to form wet steam. The diverter plate 20 is covered on the heating pan 10 and is provided with a plurality of air outlets 201 connected to the water storage tank 101. The heating tube 30 is located in the water storage tank 101 and close to the air outlet 201 and is used to heat the wet steam reaching the air outlet 201 to form superheated steam. In this way, by covering the heating pan 10 and heating it with the heating tube 30, the contact between the wet steam and the food is greatly reduced, the dryness of the steam is ensured, and the taste of the food after steaming and baking is ensured, which is conducive to improving the user experience. Furthermore, the heating plate 10 includes a plate body 11 provided with the water storage tank 101 and a heating body 12 arranged at the bottom of the plate body 11. The plate body 11 is provided with a water inlet 111 connected to the water storage tank 101, and the diverter plate 20 is arranged at the top of the plate body 11 to cover the notch of the water storage tank 101. The opening of the water inlet 111 facilitates the addition of evaporation water during the steaming and baking process. In addition, due to the introduction of the heating tube 30, the heating body 12 can be used only for evaporation of condensed water in the water storage tank 101, without having to heat the condensed water to generate steam for steaming and baking. Therefore, the heat transfer performance requirements of the plate body 11 are relatively low. For the evaporation plate assembly of the present application, the inner surface of the plate body 11 of the heating plate 10 can be provided with a double-layer or multi-layer cleaning coating, which is conducive to increasing the easy cleaning of the heating plate 10.

[0048] Optionally, in order to facilitate the collection of dirt dripping from food, the diverter plate 20 includes a central area 202 that is recessed toward the heating plate 10 and an edge area 203 that surrounds the central area 202. Further, in order to prevent the dirt from entering the water storage tank 101, the diverter plate 20 includes a plate body 21 that provides the central area 202 and the edge area 203, and a plurality of convex shells 22 that are recessed from the central area 202 of the plate body 21 in a direction away from the heating plate 10, the air outlet 201 is located in the convex shell 22, and the vertical distance between the air outlet 201 and the central area 202 is greater than the recessed distance of the central area 202. In normal use mode, dirt cannot cover the air outlet 201, and thus cannot enter the water storage tank 101, and the provision of the plurality of convex shells 22 only raises the height of the air outlet 201, and does not affect the capacity of the central area 202. It is understandable that, if it is only to prevent the dirt from entering the water tank 101, the central area 202 of the partition plate 45 can also be an upwardly convex curved surface, as long as the height of the air outlet 201 is higher than the height of the edge area 203. Optionally, in the present application, the convex shell 22 is a curved surface, so that even if the dirt drips onto the convex shell 22, it will slide down along the curved surface of the convex shell 22, and when working normally, the superheated steam emitted at the air outlet 201 will also blow away the dirt, thereby minimizing the possibility of dirt entering the water tank 101, ensuring the purity of the steam, and ensuring the cooking quality.

[0049] See also Figure 4 , Figure 4 This is a partial structural schematic diagram of an evaporation tray assembly in another embodiment provided in the present application. Figure 5 for Figure 4 A schematic diagram of the structure of the middle dividing tube 40 and the heating tube 30 from another perspective. Figure 6 for Figure 4 A cross-sectional view of the evaporator assembly is shown.

[0050] Optionally, in order to prevent the liquid in the water storage tank 101 from cooling down when cold water enters the water storage tank 101 and affecting the continuous generation of steam, in one embodiment provided in the present application, the evaporation disk assembly further includes a separation cylinder 40 located in the water storage tank 101, the separation cylinder 40 includes a first cylinder body 41 and a stop ring plate 43, the first cylinder body 41 abuts against the bottom wall of the disk body 11, the stop ring plate 43 radially extends from the outer peripheral wall of the first cylinder body 41 to the inner peripheral wall of the disk body 11, so as to divide the water storage tank 101 into a heating chamber 1011 and a buffer chamber 1012, the heating chamber 1011 is connected to the air outlet 201, and the buffer chamber 1012 is connected to the water inlet 1 11. The first cylinder 41 is also provided with a first connecting hole 411 for connecting the heating chamber 1011 and the buffer chamber 1012. The first connecting hole 411 is located on the first cylinder 41 on a side away from the water inlet 111 to prevent cold water from directly rushing into the heating chamber 1011. After the cold water enters the heating plate 10, it will flow along the buffer chamber 1012 all the way to the first connecting hole 411. During this period, the cold water will absorb the heat of the first cylinder 41, and will not directly rush into the heating chamber 1011 and mix with the liquid in the heating chamber 1011, thereby minimizing the influence of the newly added condensed water on the steam generation in the heating chamber 1011.

[0051] Furthermore, in order to reduce the leakage of wet steam and ensure the dryness of the steam flowing out of the air outlet 201, the partition cylinder 40 also includes a partition plate 45 located in the first cylinder body 41 to divide the heating chamber 1011 into a steam production space 10111 and a conversion space 10112. The steam production space 10111 is connected to the first connecting hole 411, and the conversion space 10112 is connected to the air outlet 201. The heating pipe 30 is located in the conversion space 10112. The partition plate 45 is also provided with a plurality of steam channels 451 connecting the steam production space 10111 and the conversion space 10112. In this way, by arranging the partition plate 45 on the path of the steam, the wet steam in the steam production space 10111 will be fully vaporized by the heating pipe 30 and converted into superheated steam after entering the conversion space 10112, that is, the dryness of the steam is improved and the latent heat of the steam is increased.

[0052] Furthermore, in order to increase the circulation path of the cold flow and reduce the influence of the newly added cold flow of the heating disk 10 on the boiling liquid in the water storage tank 101, in one embodiment provided in the present application, the partition cylinder 40 further includes a second cylinder 42, which is surrounded by the first cylinder 41 and the partition plate 45 to form a heat-insulating space 10113, and a plurality of second connecting holes 421 are opened on the side of the second cylinder 42 close to the bottom wall of the disk body 11. In this way, the cold flow needs to flow from the first connecting hole 411 along the outer peripheral wall of the second cylinder 42 to the second connecting hole 421 before entering the steam production space 10111, which further increases the circulation path of the cold flow, and there is a heat-insulating space 10113 between the cold flow in the buffer cavity 1012 and the hot flow in the steam production space 10111, which can minimize the loss of heat in the steam production space 10111 and ensure that the steam production space 10111 will not be temporarily unable to produce steam when adding cold water.

[0053] Optionally, in an embodiment provided in the present application, a plurality of second connecting holes 421 are symmetrically arranged along the line connecting the water inlet 111 and the first connecting hole 411, so that when the cold flow enters the steam production space 10111 from different second connecting holes 421, the impact on the steam production space 10111 is more uniform, thereby avoiding the temperature field disorder in the steam production space 10111.

[0054] Optionally, in order to ensure the position stability of the separation cylinder 40 in the heating disk 10 and avoid the problem that the separation cylinder 40 floats due to the buoyancy in the heat-insulating space 10113, in one embodiment provided in the present application, the separation cylinder 40 further includes a support ring plate 44 extending from the first cylinder body 41, and the support ring plate 44 abuts against the bottom wall of the disk body 11 in the axial direction and the inner peripheral wall of the disk body 11 in the radial direction. Preferably, the support ring plate 44 is attached to the bottom wall of the disk body 11, so that under the gravity of the liquid in the buffer chamber 1012, the separation cylinder 40 is pressed against the disk body 11, and at the same time, it is restricted by the inner peripheral wall of the disk body 11, and the separation cylinder 40 will not shake easily. From another perspective, when the evaporation disk assembly is filled with liquid, under the action of atmospheric pressure, even if the separation cylinder 40 is moved and pulled in the direction away from the bottom wall of the disk body 11, a negative pressure will be formed between the support ring plate 44 and the disk body 11, thereby preventing the separation cylinder 40 from being taken out.

[0055] 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.

[0056] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
