Description

Technical Field

[0001] The utility model belongs to the technical field of ovens, and in particular relates to a humidifying component for an oven and the oven. Background Art

[0002] In order to bake bread that is crispy on the outside and tender on the inside in an oven, there are some humidifying components made of water-absorbing ceramics. The humidifying components absorb water and energy by utilizing the water absorption and energy absorption of ceramics. After the humidifying components absorb water, they are placed in an oven and baked together with the bread. When the ceramics are heated, the internal moisture evaporates to form water vapor, which forms a layer of water film on the outside of the bread. Because water heats faster than gas, the surface of the bread will char faster, thereby locking in the moisture inside the bread, making it crispy on the outside and tender on the inside.

[0003] Water-absorbing ceramic humidification components are currently mainly designed in a box shape, with most of their surfaces being large flat or curved surfaces. It is difficult to improve surface utilization and the evaporation efficiency is limited. In addition, after the water inside the humidification component evaporates, condensed water is formed when the water vapor is cooled. The condensed water easily adheres to the top of the humidification component, affecting the further evaporation of water inside the humidification component and reducing the evaporation efficiency of the humidification component. Utility Model Content

[0007] A water-absorbing ceramic matrix, wherein a guide surface inclined up and down is formed on the top of the water-absorbing ceramic matrix, and a lower edge of the guide surface extends to a side edge of the water-absorbing ceramic matrix;

[0008] A wavy area extending along a preset direction is formed on the guide surface, the upper edge of the wavy area extends to the upper edge of the guide surface, the lower edge of the wavy area extends to the lower edge of the guide surface, and a guide groove is formed between two adjacent wave peaks of the wavy area; wherein the preset direction is parallel to the lower supporting surface of the water-absorbing ceramic substrate and perpendicular to the corresponding inclination direction of the guide surface.

[0009] In combination with the first aspect, in a possible implementation manner, the wavy area completely covers the guide surface.

[0010] In some embodiments, the crest of the wavy area is curved.

[0013] In some embodiments, two guide surfaces are provided, and the two guide surfaces are arranged opposite to each other.

[0014] In some embodiments, the two guide surfaces are symmetrically arranged about a preset axis, and the preset axis is the intersection line of the two guide surfaces.

[0015] In combination with the first aspect, in a possible implementation manner, an angle between the guide surface and the lower supporting surface of the water absorbing ceramic substrate is 2° to 20°.

[0016] In combination with the first aspect, in a possible implementation manner, the water-absorbing ceramic matrix is ​​a solid plate.

[0017] Compared with the prior art, the scheme shown in the embodiment of the present application has the following beneficial effects: 1) a guide surface inclined up and down is formed on the top of the water-absorbing ceramic substrate, and the condensed water on the top will flow along the guide surface to the side edge of the water-absorbing ceramic substrate, and finally slide down the side wall of the water-absorbing ceramic substrate. In particular, after the guide groove is formed, the guide groove has a gathering effect on the condensed water, further avoiding the phenomenon of condensed water condensing on the top of the water-absorbing ceramic substrate, thereby avoiding the problem of condensed water affecting the evaporation of water inside the water-absorbing ceramic substrate; 2) by forming a wavy area, without expanding the lateral size of the water-absorbing ceramic substrate, the top space of the water-absorbing ceramic substrate is fully utilized, thereby effectively increasing the top surface area of ​​the water-absorbing ceramic substrate, and ultimately improving the evaporation efficiency of water inside the water-absorbing ceramic substrate by increasing the surface heating area.

[0018] In a second aspect, the present application also provides an oven, comprising an oven main body and the above-mentioned humidifying component for the oven.

[0019] Compared with the prior art, the solution shown in the embodiment of the present application adopts the above-mentioned humidifying component for the oven to prevent condensed water from affecting the evaporation efficiency of the humidifying component for the oven. At the same time, the evaporation efficiency of the internal water is improved by increasing the heated area of ​​the surface, which promotes further improvement of the baking effect and is beneficial to improving the quality of the oven.

[0034] Please also read Figures 1 to 7 Now, the humidifying component 1 for an oven provided by the utility model is described. The humidifying component 1 for an oven comprises a water-absorbing ceramic substrate 10, the top of which is formed with a guide surface 20 inclined up and down, the lower edge of which extends to the side edge of the water-absorbing ceramic substrate 10; a wavy area 210 extending along a preset direction is formed on the guide surface 20, the upper edge of the wavy area 210 extends to the upper edge of the guide surface 20, the lower edge of the wavy area 210 extends to the lower edge of the guide surface 20, and a guide groove 211 is formed between two adjacent wave crests 2101 of the wavy area 210; wherein the preset direction is parallel to the lower support surface of the water-absorbing ceramic substrate 10, and perpendicular to the corresponding inclination direction of the guide surface 20.

[0035] In this embodiment, the water-absorbing ceramic substrate 10 can be in the shape of a block or plate, etc., which can fit into the internal space of the oven body 2 and have a large cross-sectional area on the cross section perpendicular to the up and down direction. The material of the water-absorbing ceramic substrate 10 includes but is not limited to porous water-absorbing ceramic material.

[0036] In this embodiment, the lower surface of the water-absorbing ceramic matrix 10 is a plane, and the lower surface of the water-absorbing ceramic matrix 10 is the lower support surface; or, the bottom of the water-absorbing ceramic matrix 10 has a plurality of coplanar support positions, and the surface where these support positions are located is the lower support surface of the water-absorbing ceramic matrix 10. The inclination direction of the guide surface 20 refers to: the intersection line of the guide surface 20 and the lower support surface of the water-absorbing ceramic matrix 10 is defined as the first intersection line, which is located on the guide surface 20 and is perpendicular to the direction of the first intersection line.

[0037] In this embodiment, the number of the guide surface 20 can be one or more, and is not limited to the number of guide surfaces 20. Taking the example of a solution in which one guide surface 20 is provided, the configuration of the guide surface 20 includes but is not limited to the following: (1) The upper edge of the guide surface 20 extends to one side edge of the water-absorbing ceramic substrate 10, and the lower edge extends to the other side edge of the water-absorbing ceramic substrate 10, and in a preset direction, the two end edges of the guide surface 20 extend to the two end edges of the water-absorbing ceramic substrate 10 respectively, such as Figures 2 to 7As shown; (2) the upper edge of the guide surface 20 extends to one side edge of the water-absorbing ceramic matrix 10, and the lower edge extends to the other side edge of the water-absorbing ceramic matrix 10. In the preset direction, the two end edges of the guide surface 20 do not extend to the two end edges of the water-absorbing ceramic matrix 10, which is not shown in the figure; (3) the upper edge of the guide surface 20 extends to one side edge of the water-absorbing ceramic matrix 10, and the lower edge extends to the other side edge of the water-absorbing ceramic matrix 10. In the preset direction, one end edge of the guide surface 20 extends to the corresponding edge of the water-absorbing ceramic matrix 10, and the other end edge does not extend to the corresponding edge of the water-absorbing ceramic matrix 10, which is not shown in the figure; (4) the upper edge of the guide surface 20 extends to one side edge of the water-absorbing ceramic matrix 10, and the lower edge extends to the other side edge of the water-absorbing ceramic matrix 10. In the preset direction, the setting method of the two end edges of the guide surface 20 refers to the aforementioned methods (1) to (3). In method (4), the upper edge of the guide surface 20 and the corresponding side edge of the water-absorbing ceramic matrix 10 can be a plane in the vertical direction or a curved surface, and no sole limitation is made here. In addition, in order to avoid condensation water; in addition, it is necessary to keep the upper edge of the guide surface 20 and the corresponding side edge of the water-absorbing ceramic matrix 10 within a smaller range to avoid a large amount of condensation water accumulation in this area.

[0038] Compared with the prior art, the humidifying component 1 for an oven provided in the present embodiment has the following beneficial effects: 1) a guide surface 20 inclined up and down is formed on the top of the water-absorbing ceramic substrate 10, and the condensed water on the top will flow along the guide surface 20 to the side edge of the water-absorbing ceramic substrate 10, and finally slide down along the side wall of the water-absorbing ceramic substrate 10, especially after the guide groove 211 is formed, the guide groove 211 has a gathering effect on the condensed water, further avoiding the phenomenon that the condensed water condenses on the top of the water-absorbing ceramic substrate 10, thereby avoiding the problem that the condensed water affects the evaporation of water inside the water-absorbing ceramic substrate 10; 2) by forming the wavy area 210, without expanding the lateral size of the water-absorbing ceramic substrate 10, the top space of the water-absorbing ceramic substrate 10 is fully utilized, the top surface area of ​​the water-absorbing ceramic substrate 10 is effectively increased, and the evaporation efficiency of the water inside the water-absorbing ceramic substrate 10 is finally improved by increasing the surface heating area.

[0039] In order to maximize the top surface area of ​​the water-absorbing ceramic substrate 10, in some embodiments, the wavy region 210 completely covers the guide surface 20, that is, in a preset direction, the two end edges of the wavy region 210 extend to the two end edges of the guide surface 20, such as Figure 2 and Figure 5 The full coverage of the wavy area 210 not only provides a larger top surface area, but also enables the guide grooves 211 to have a wider distribution range, thereby forming more confluence areas on the guide surface 20 and achieving a better guide effect on condensed water.

[0040] Of course, the wavy area 210 may not completely cover the guide surface 20. Figure 7 The guide surface 20 not covered by the wavy area 210 may be an inclined plane or an inclined curved surface. In this embodiment, the uncovered area is exemplarily shown as an inclined plane structure.

[0041] In some specific embodiments of the wavy region 210 , the wave crests 2101 and the wave troughs 2102 of the wavy region 210 include, but are not limited to, sharp angles less than 90°, so that the wavy region 210 is sawtooth-shaped.

[0042] participate Figure 3 In other specific embodiments of the wavy area 210, the crest 2101 of the wavy area 210 is an upwardly convex arc surface. On the one hand, it can enhance the load-bearing capacity of the crest 2101 area and reduce the risk of damage caused by pits at the crest 2101. On the other hand, it can also enhance the guiding effect on condensed water, making it easier for the condensed water to converge into the guide groove 211.

[0043] participate Figure 3 In some specific embodiments of the wavy region 210, the trough 2102 of the wavy region 210 is a downwardly concave arc surface, wherein the trough 2102 corresponds to the bottom surface of the guide groove 211. By designing the bottom surface of the guide groove 211 to be an arc surface, a dead angle is avoided at the bottom of the guide groove 211, which is convenient for cleaning and can also enhance the diversion effect on condensed water. More specifically, the bottom surface of the guide groove 211 and the side wall of the guide groove 211 have a smooth transition.

[0044] It should be noted that the solution in which the crest 2101 is an arc surface and the solution in which the trough 2102 is an arc surface can be used alone or in combination. This embodiment exemplarily shows the combination of the two.

[0045] In some embodiments, there are multiple guide surfaces 20, and the inclination direction of each guide surface 20 is different; the guide grooves 211 on two adjacent guide surfaces 20 correspond to each other, and the tops of the inner walls of the two corresponding guide grooves 211 are connected to each other. The multiple guide surfaces 20 of this embodiment are not parallel to each other, so as to realize multi-directional flow guidance of condensed water, and effectively shorten the guide path (the length of the guide path corresponds to the length of the guide groove 211), thereby improving the guide efficiency; and the design of multiple non-parallel guide surfaces 20 also effectively increases the area of ​​the guide surface 20. On the basis of the larger area of ​​the guide surface 20, it can be ensured that the wavy area 210 has a larger coverage area; in addition, by connecting the guide grooves 211 on different backflow surfaces, the condensed water formed at the intersection of the two guide surfaces 20 can freely enter the guide groove 211 on one side.

[0046] In this embodiment, if two adjacent guide surfaces 20 directly intersect with each other, the side walls of the two corresponding guide grooves 211 are directly connected; if the two adjacent guide surfaces 20 do not directly intersect with each other (that is, the extended surfaces of the two guide surfaces 20 intersect), there is a spacing surface between the two guide surfaces 20 (the implementation methods of the spacing surface include but are not limited to a plane and a curved surface), and a connecting groove is opened on the spacing surface to connect the two guide grooves 211.

[0047] In this embodiment, two or more guide surfaces 20 may be provided. Taking the case where three guide surfaces 20 are provided as an example, the three guide surfaces 20 are distributed around the axis of the water-absorbing ceramic substrate 10 and penetrate the axis up and down, and two adjacent guide surfaces 20 directly intersect. Other implementations are not listed here one by one.

[0048] On the basis of the above embodiment, the tops of the inner walls of two adjacent and corresponding guide grooves 211 are transitioned through an upwardly convex arc surface. On the one hand, the bearing capacity of the connecting area at the top of the two guide grooves 211 can be enhanced, and the risk of damage to the area caused by pit collision can be reduced. On the other hand, the guiding effect on condensed water can be enhanced, so that the condensed water can be more easily gathered in the guide groove 211.

[0049] In some embodiments, in order to simplify the design of the guide surface 20 and ensure that the guide path is short, two guide surfaces 20 are provided, and the two guide surfaces 20 are arranged opposite to each other, wherein the tops of the two guide surfaces 20 can intersect directly, or the extended surfaces of the two guide surfaces 20 can intersect.

[0050] On the basis of the above embodiment, in order to further simplify the design of the guide surface 20, see Figure 2 , Figure 4 , Figure 5 and Figure 7 The two guide surfaces 20 are symmetrically arranged about a preset axis, and the preset axis is the intersection line of the two guide surfaces 20, wherein the intersection line can be an intersection line formed by directly intersecting the tops of the two guide surfaces 20, or an intersection line formed by intersecting the extended surfaces of the two guide surfaces 20.

[0051] In some embodiments, in order to maximize the top surface area of ​​the water-absorbing ceramic matrix 10 while ensuring the diversion effect, the angle between the diversion surface 20 and the lower support surface of the water-absorbing ceramic matrix 10 is 2° to 20°. In specific implementations, the angle between the diversion surface 20 and the lower support surface includes but is not limited to 4°, 4.5°, 5°, 5.5°, 6°, 8°, 10°, 12°, 15°, and 17°.

[0052] If the water-absorbing ceramic substrate 10 is designed in a block shape, the water-absorbing ceramic substrate 10 has a large thickness and a slow heat conduction, which affects the evaporation efficiency of the internal water to a certain extent; if the water-absorbing ceramic substrate 10 is designed as a hollow box structure, although its wall thickness is small, the side walls and heating tubes in different areas are different, resulting in uneven heating. In order to solve these problems, refer to Figures 1 to 5 and Figure 7 In some embodiments, the water-absorbing ceramic substrate 10 is a solid plate-shaped component. The plate-shaped design makes the overall thickness of the water-absorbing ceramic substrate 10 smaller, the heat conduction is faster, and the internal water can be evaporated faster; at the same time, due to the solid design, the problem of uneven heating is avoided; in addition, the plate-shaped design greatly compresses the size of the water-absorbing ceramic substrate 10 in the vertical direction, and then the plate surface area can be appropriately expanded without affecting the weight of the water-absorbing ceramic substrate 10 too much, ensuring the evaporation efficiency while not affecting the convenience of the user's grasping and transfer.

[0053] In some specific embodiments of the water-absorbing ceramic substrate 10, the water-absorbing ceramic substrate 10 is a polygonal plate, and two adjacent sides of the water-absorbing ceramic substrate 10 are transitioned by a curved surface. This embodiment exemplarily shows the case where the water-absorbing ceramic substrate 10 is a rectangular plate, and all four corners thereof are rounded (i.e., two adjacent sides are transitioned by a curved surface).

[0054] In other specific embodiments of the water-absorbing ceramic matrix 10, the water-absorbing ceramic matrix 10 may also be a circular plate, an elliptical plate, etc., which is not limited here.

[0055] In some embodiments, in order to further ensure the reliability of the condensed water flowing from the guide surface 20 to the side wall surface of the water-absorbing ceramic substrate 10, see Figure 4 The guide surface 20 and the side wall surface of the water-absorbing ceramic substrate 10 are transitioned through an arc surface.

[0056] Based on the same inventive concept, the present application embodiment also provides an oven, see Figure 1 The oven includes an oven body 2 and the above-mentioned oven humidifying component 1.

[0057] Compared with the prior art, the oven provided in this embodiment adopts the above-mentioned humidifying component 1 for the oven to prevent condensed water from affecting the evaporation efficiency of the humidifying component 1 for the oven, and at the same time improves the evaporation efficiency of the internal water by increasing the heated area of ​​the surface, which promotes further improving the baking effect and is beneficial to improving the quality of the oven.

[0058] In some embodiments, the oven humidifying component 1 can be placed on the same baking rack as the food to be baked (such as bread); or, a bracket specifically for placing the oven humidifying component 1 is provided at the bottom of the oven body 2.

[0059] If a bracket is provided, a limiting protrusion may be provided on the bracket to limit the periphery of the oven humidifying member 1 (i.e., limit the position in a direction perpendicular to the up and down direction) to prevent the oven humidifying member 1 from directly touching the inner wall of the oven body 2. More specifically, the limiting protrusion may be provided as a continuous annular structure, and the limiting protrusion may also form a groove structure, which may not only limit the oven humidifying member 1, but also gather the condensed water flowing down from the oven humidifying member 1 to prevent the condensed water from overflowing from the bracket and affecting other components in the oven.

[0060] This embodiment exemplarily shows an embodiment in which the bracket is arranged below the oven heating tube, but it should be understood that the bracket can also be arranged above the heating tube and selectively arranged according to actual baking requirements.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
