[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. All publications, patent applications, patents, and other references mentioned herein are incorporated by reference in their entirety.
[0049] The existing electric steamer, including the steam base and the steamer assembly, usually the steamer assembly and the steam base are matched by the stepped surface, so as to limit the steamer assembly on the steam base, avoiding its movement along the horizontal direction relative to the steam base. When using, since the water amount is invisible, when adding water in the middle, the whole steamer assembly needs to be taken down along the height direction, which is easy to be scalded by the steam, and the condensed water on the steaming rack will also scatter on the table surface, which is very inconvenient. Some existing steamer assemblies are mainly formed by plastic injection molding or hardware material stretching molding, no matter what material is made, the steamer assembly needs to be taken down as a whole when adding water. The applicant designs an electric steamer with a steamer assembly capable of sliding relative to the steam base, and the existing steamer structure cannot meet the sliding relative to the steam base.
[0050] In order to solve the above problems, as shown in Figures 1 to 17 The utility model provides a kind of steaming rack 10 and electric steamer, so that steaming rack 10 can slide relative to steam base 200, and steaming rack 10 can be prevented from being deformed.
[0051] As shown in Figures 3 to 5 Specifically, the steaming rack 10 has a supporting area 11 and an edge area 12 located outside the supporting area 11, and the steaming rack 10 includes a plurality of strip-shaped support ribs 111, which are arranged in the supporting area 11. The back of the steaming rack 10 has a matching surface 121 and a sliding surface 113, the matching surface 121 is located in the edge area 12, and the sliding surface 113 is located inside the matching surface 121, and the sliding surface 113 is lower than the matching surface 121. The steaming rack 10 has a sliding direction, which is perpendicular to the length direction a of at least part of the support ribs 111.
[0052] The steam rack 10 can be arranged on the steam base 200. When the steam rack 10 is arranged on the steam base 200, the upward face of the steam rack 10 is the front face, and the downward face of the steam rack 10 is the back face.
[0053] In the steam rack 10, in the working state, the matching face 121 of the steam rack 10 can be lapped on the supporting top face 201 of the steam base 200, the steam rack 10 completely covers the steam base 200, the internal structure of the steam base 200 is not exposed, and steam leakage in the steam base 200 is avoided. Since the sliding face 113 is lower than the matching face 121, the sliding face 113 is lower than the matching face 121, so that a step structure capable of limiting the steam rack 10 is formed between the sliding face 113 and the matching face 121. Without external force, the steam rack 10 can be stably arranged on the steam base 200, and the steam base 200 can heat water to heat food placed on the supporting area 11. When it is necessary to observe the water level in the steam base 200 or to add water to the steam base 200, the steam rack 10 can be controlled to slide relative to the steam base 200 along the sliding direction to open to a sliding state. In the sliding state, the matching face 121 and the sliding face 113 can be lapped on the supporting top face 201 of the steam base 200, so that the steam rack 10 is stably arranged on the steam base 200 through the matching face 121 and the sliding face 113, and the steam rack 10 is partially misaligned with the steam base 200, so that the internal structure of the steam base 200 is partially exposed, and the user can observe the water level in the steam base 200 or add water to the steam base 200 through the misaligned part of the steam rack 10 and the steam base 200. Finally, the steam rack 10 is controlled to slide relative to the steam base 200 in the reverse direction along the sliding direction to reset to the working state, so that the steam rack 10 is lapped on the supporting top face 201 of the steam base 200 through the matching face 121 again.
[0054] Furthermore, since the length direction a of at least part of the supporting ribs 111 is perpendicular to the sliding direction of the steam rack 10, the strength of the supporting area 11 in the sliding direction can be increased, so that after heavy food is placed on the supporting area 11, the two ends of the supporting area 11 in the sliding direction are prevented from being partially deformed and sunken, the initial resistance when the user controls the steam rack 10 to slide relative to the steam base 200 along the sliding direction to open is increased, the use experience is affected, or the matching face 121 interferes with the steam base 200 when the user controls the steam rack 10 to slide relative to the steam base 200 in the reverse direction along the sliding direction to reset, the resistance is increased, and even the reset cannot be completed.
[0055] It should be noted that the steaming rack 10 can be a rectangular structure as shown, which includes two parallel long sides and two parallel short sides, so as to facilitate the user to control the steaming rack 10 to slide along the extension direction of the long side or the extension direction of the short side relative to the steam base 200, and ensure the stability of the steaming rack 10 on the steam base 200. Of course, the steaming rack 10 can also be a square, polygon, circle or other shape, as long as the steaming rack 10 can slide relative to the steam base 200 along the sliding direction, and the embodiments of the present application do not make specific limitations here. For the sake of description, the following will be described by taking the rectangular structure of the steaming rack 10 as an example, wherein the long side of the steaming rack 10 extends along the X-axis direction, and the short side extends along the Y-axis direction.
[0056] As shown in Figures 2 to 3 In one embodiment, the steaming rack 10 can slide relative to the steam base 200 along the Y-axis direction, that is, the sliding direction of the steaming rack 10 is the Y-axis direction, and at this time, the length direction a of at least part of the support ribs 111 extends along the X-axis direction. At this time, the steaming rack 10 can be controlled to slide open relative to the steam base 200 along the -Y-axis direction, and the steaming rack 10 can be controlled to slide open relative to the steam base 200 along the +Y-axis direction. In addition, the steaming rack 10 can be controlled to slide open relative to the steam base 200 along the +Y-axis direction, and the steaming rack 10 can be controlled to slide open relative to the steam base 200 along the -Y-axis direction.
[0057] As shown in Figures 12 to 13 In another embodiment, the steaming rack 10 can slide relative to the steam base 200 along the X-axis direction, that is, the sliding direction of the steaming rack 10 is the X-axis direction, and at this time, the length direction a of at least part of the support ribs 111 extends along the Y-axis direction. At this time, the steaming rack 10 can be controlled to slide open relative to the steam base 200 along the -X-axis direction, and the steaming rack 10 can be controlled to slide open relative to the steam base 200 along the +X-axis direction. In addition, the steaming rack 10 can be controlled to slide open relative to the steam base 200 along the +X-axis direction, and the steaming rack 10 can be controlled to slide open relative to the steam base 200 along the -X-axis direction.
[0058] As shown in Figures 3 to 4 A plurality of steam holes 112 are arranged on the supporting area 11 of the steaming rack 10, and the plurality of steam holes 112 are arranged between the support ribs 111. The steam generated by the steam base 200 heating water flows upward through the steam holes 112 to heat the food placed on the supporting area 11.
[0059] As shown in Figure 4 and Figure 13As shown, the support ribs 111 are arranged in rows, and at least one row of steam holes 112 is provided between any two adjacent rows of support ribs 111. Each row of steam holes 112 is formed by multiple spaced steam holes 112. The length direction 'a' of the support ribs 111 in the same row is on the same straight line, and the centers of the steam holes 112 in the same row are on the same straight line. Only one row of steam holes 112 can be provided between any two adjacent rows of support ribs 111, or two, three, or more rows can be provided as needed. Specifically, when the sliding direction of the steam rack 10 is... Figure 4 When the Y-axis direction is shown, the straight line containing the length direction 'a' of each row of support ribs 111 extends along the X-axis direction, and the straight line containing the center of each row of steam holes 112 also extends along the X-axis direction. Along the Y-axis direction, the steam holes 112 and support ribs 111 are arranged alternately. This ensures that the steam holes 112 are evenly distributed on the steam rack 10, guaranteeing that the steam in the steam base 200 flows upward evenly through the steam holes 112. Simultaneously, it prevents the support area 11 from being prone to bending deformation or even breakage due to an excessive number of steam holes 112 in the sliding direction of the steam rack 10, thus improving the strength and reliability of the support area 11. Similarly, when the sliding direction of the steam rack 10 is... Figure 13 In the X-axis direction shown, the straight line containing the length direction a of each row of support ribs 111 extends along the Y-axis direction, and the straight line containing the center of each row of steam holes 112 extends along the Y-axis direction. Along the X-axis direction, the steam holes 112 and support ribs 111 are arranged alternately.
[0060] like Figure 7 As shown, adjacent rows of steam holes 112 are staggered. Specifically, when the sliding direction of the steam rack 10 is... Figure 4 When the Y-axis direction is shown, the centers of two adjacent rows of steam holes 112 are not on the same straight line along the Y-axis direction; similarly, when the sliding direction of the steam rack 10 is... Figure 13 When viewed along the X-axis, the centers of two adjacent rows of steam holes 112 are not on the same straight line. This further prevents bending deformation or even breakage of the support area 11 in the sliding direction of the steam rack 10 due to an excessive number of steam holes 112, which would result in a low moment of inertia at that section. This further enhances the strength and reliability of the support area 11 in the sliding direction of the steam rack 10.
[0061] like Figure 4 and Figure 13 As shown, each row of support ribs 111 is formed by at least one support rib 111. Specifically, a row of support ribs 111 can be formed by a single support rib 111, for example... Figure 4 Both rows of support ribs 111 at both ends along the Y-axis are formed by a single support rib 111. Figure 13The two rows of support ribs 111 at the two ends along the X-axis direction are formed by one piece of support rib 111. One piece of complete support rib 111 can improve the strength of the row of support ribs 111, and therefore, the two rows of support ribs 111 at the two ends along the sliding direction are formed by one piece of support rib 111, which can improve the strength of the two ends of the supporting area 11 along the sliding direction, prevent the two ends of the supporting area 11 along the sliding direction from being locally deformed and sunk, and affect the user to control the steamer 10 to slide relative to the steam base 200 along the sliding direction. Alternatively, the row of support ribs 111 can also be formed by two, three or more pieces of support ribs 111 according to the needs, so as to facilitate the processing of the steam holes 112 and other structures on the supporting area 11.
[0062] As shown in Figure 4 and Figure 13 The supporting area 11 of the steamer 10 is also provided with an egg steaming groove 114, and the support rib 111 extending through the egg steaming groove 114 is divided into multiple sections. The egg steaming groove 114 is used to place eggs to avoid rolling on the supporting area 11. The support rib 111 extending through the egg steaming groove 114 is divided into multiple sections, so as to facilitate the processing of the egg steaming groove 114 and the support rib 111 on the supporting area 11, and also can prevent the supporting area 11 from being locally processed to cause the cross-section moment of inertia of the section to be too low to easily bend and deform or even break, thereby improving the strength and reliability of the supporting area 11.
[0063] As shown in Figure 4 and Figure 13 Since the egg steaming groove 114 is a downwardly recessed structure, the bottom of the egg steaming groove 114 is lower than other areas on the supporting area 11. To prevent the condensed water on the supporting area 11 from flowing into the egg steaming groove 114 and accumulating in the egg steaming groove 114 to affect the cooking effect, a through hole 115 can be formed at the bottom of the egg steaming groove 114, so that the condensed water flowing into the egg steaming groove 114 can drop into the steam base 200 through the through hole 115.
[0064] As shown in Figure 4 and Figure 13As shown, the steaming rack 10 is also provided with a ring-shaped backflow groove 13, the bottom surface of the backflow groove 13 is a sliding surface 113, and the groove bottom of the backflow groove 13 is provided with a backflow hole 131. Since the backflow groove 13 is a downwardly recessed structure, the bottom surface of the backflow groove 13 can be used as the sliding surface 113, so that the structure of the steaming rack 10 is simple, and the sliding surface 113 is easy to process. The groove bottom of the backflow groove 13 is lower than other areas on the steaming rack 10, and the condensed water on the steaming rack 10 can flow into the backflow groove 13 and drip into the steam base 200 through the backflow hole 131, preventing the condensed water from accumulating on the steaming rack 10 and affecting the cooking effect. In an embodiment, the backflow groove 13 is arranged at the edge of the supporting area 11, or the backflow groove 13 can also be arranged at the joint of the supporting area 11 and the edge area 12, so that there is enough area inside the supporting area 11 to process other structures such as the supporting ribs 111, the steam holes 112, the egg steaming groove 114, etc., avoiding the influence of the condensed water in the backflow groove 13 on the cooking effect, and also avoiding the increase in the size of the edge area 12 due to the arrangement of the backflow groove 13 in the edge area 12. Of course, in other embodiments, the backflow groove 13 can be arranged at other positions of the supporting area 11 or in the edge area 12 as needed.
[0065] In an embodiment, the backflow groove 13 includes a first backflow groove 132 and a second backflow groove 133, the bottom surface of the first backflow groove 132 is the sliding surface 113, the groove bottom of the second backflow groove 133 is lower than the groove bottom of the first backflow groove 132, and the backflow hole 131 is arranged at the groove bottom of the second backflow groove 133. The condensed water on the steaming rack 10 can first flow into the first backflow groove 132, the condensed water in the first backflow groove 132 can then flow into the second backflow groove 133, and finally the condensed water in the second backflow groove 133 can drip into the steam base 200 through the backflow hole 131. When the sliding direction of the steaming rack 10 is the Y-axis direction as shown, the second backflow groove 133 is arranged at both ends of the steaming rack 10 along the X-axis direction, avoiding the reduction of the strength of the steaming rack 10 in the sliding direction; similarly, when the sliding direction of the steaming rack 10 is the X-axis direction as shown, the second backflow groove 133 is arranged at both ends of the steaming rack 10 along the Y-axis direction. Figure 4 Figure 13 Of course, in other embodiments, the backflow hole 131 can be arranged at the groove bottom of both the first backflow groove 132 and the second backflow groove 133; or the backflow groove 13 can only include the first backflow groove 132, and the backflow hole 131 can be arranged at the groove bottom of the first backflow groove 132.
[0066] As shown in FIG. 1, the steaming rack 10 is provided with a plurality of supporting ribs 111, and the supporting ribs 111 are arranged in the supporting area 11. The supporting ribs 111 are arranged in the supporting area 11 to support the food to be steamed, and the supporting ribs 111 are arranged in the supporting area 11 to form a plurality of steam holes 112. The steam holes 112 are arranged in the supporting ribs 111 to allow steam to pass through the steam holes 112 and contact the food to be steamed. The supporting ribs 111 are arranged in the supporting area 11 to form an egg steaming groove 114. The egg steaming groove 114 is arranged in the supporting area 11 to accommodate an egg to be steamed. Figures 15 to 17 As shown, the reflux trough 13 has a recessed portion 134 facing inward toward the steam rack 10, and a reflux hole 131 is located in the recessed portion 134. When the cage body 20 or the cover body 300 is placed on the steam rack 10, the bottom of the cage body 20 or the cover body 300 may overlap in the reflux trough 13. The recessed portion 134 can prevent the bottom of the cage body 20 or the cover body 300 from pressing on the reflux hole 131, thus preventing steam leakage from the reflux hole 131. The recessed portion 134 can be located on both sides of the steam rack 10 along the sliding direction, or it can be located in other positions as needed. Specifically, the distance L between the bottom of the cage body 20 or the cover body 300 and the reflux hole 131 satisfies L≥0.5mm to avoid assembly errors causing the bottom of the cage body 20 or the cover body 300 to press on the reflux hole 131.
[0067] like Figure 4 and Figure 13 As shown, the steaming rack 10 is provided with annular reinforcing ribs 14. The reinforcing ribs 14 are located at the edge of the support area 11, or they can be located at the junction of the support area 11 and the edge area 12. The annular reinforcing ribs 14 can improve the strength of the edge of the support area 11, preventing the edge of the support area 11 from deforming and sinking locally after heavy food is placed on it, thus affecting the user's control of the steaming rack 10 to slide relative to the steam base 200 in the sliding direction, thereby ensuring the overall flatness of the steaming rack 10. When the steaming rack 10 is provided with annular return grooves 13, the return grooves 13 are preferably located outside the reinforcing ribs 14, preventing the return grooves 13 from being close to structures such as steam holes 112 or egg steaming grooves 114, which would cause the section moment of inertia of that section to be too low and easily bend, deform, or even break, thereby improving the strength and reliability of the support area 11.
[0068] like Figure 4 and Figure 8 As shown, the number of reinforcing ribs 14 can be one, two, or more. When the number of reinforcing ribs 14 is... Figure 8 In the two cases shown, one reinforcing rib 14 surrounds the outer periphery of the other reinforcing rib 14. This further enhances the strength of the edge of the supporting area 11 and improves the overall flatness of the steam rack 10. Of course, when the sliding direction of the steam rack 10 is... Figure 13 In the X-axis direction shown, since the long side of the steam rack 10 has relatively good resistance to deformation, the reinforcing rib 14 can be omitted, so that there is enough area on the support area 11 to process other structures such as the supporting rib 111, steam hole 112, and egg steaming groove 114 to ensure the cooking effect.
[0069] like Figure 15 As shown, the reinforcing rib 14 may also be provided with a concave section 141 that is recessed towards the inside of the steam rack 10, and the concave section 141 is arranged corresponding to the concave part 134 of the return channel 13.
[0070] likeFigures 4 to 5 As shown, in one embodiment, the support rib 111 protrudes from the support area 11 on the front side of the steamer rack 10. This prevents condensate from flowing into and accumulating within the support rib 111, thus affecting the cooking effect, because the bottom of the support rib 111 is lower than other areas on the support area 11 when it is recessed. Of course, in other embodiments, the support rib 111 can also be recessed from the support area 11 on the front side of the steamer rack 10, that is, the support rib 111 protrudes from the support area 11 on the back side of the steamer rack 10.
[0071] like Figures 9 to 11 As shown, the height difference H1 between the sliding surface 113 and the mating surface 121 satisfies 0.5mm ≤ H1 ≤ 5mm. The height difference H1 can be any value within the range of 0.5mm ≤ H1 ≤ 5mm, such as 0.5mm, 0.6mm…1mm, 2mm, 3mm, 4mm, 5mm, etc. A height difference H1 ≥ 0.5mm ensures the limiting effect of the stepped structure formed between the sliding surface 113 and the mating surface 121 on the steam rack 10, preventing the steam rack 10 from shifting along the sliding direction and ensuring that the steam rack 10 can be stably mounted on the steam base 200. A height difference H1 ≤ 5mm prevents the user from controlling the steam rack 10 to slide open relative to the steam base 200 along the sliding direction, causing the mating surface 121 and the sliding surface 113 to overlap the supporting top surface 201 of the steam base 200, resulting in an excessively large tilt angle of the steam rack 10.
[0072] like Figure 5 , Figure 6 and Figure 14 As shown, a transition section 15 is provided between the sliding surface 113 and the mating surface 121. In one embodiment, a protrusion 151 is provided on the transition section 15. The protrusion 151 can reduce the contact area between the top surface of the steam rack 10 and the top surface of the steam base 200, changing the line-surface fit between the transition section 15 and the top surface of the steam base 200 into a point-surface fit between the protrusion 151 and the top surface of the steam base 200. This reduces the friction between the top surface of the steam rack 10 and the top surface of the steam base 200, reducing the force required for the user to control the steam rack 10 to slide relative to the steam base 200 in the sliding direction, making the user operation smoother. Specifically, when the sliding direction of the steam rack 10 is... Figure 4 When the Y-axis direction is shown, the protrusions 151 are provided at both ends of the transition section 15 along the Y-axis direction; when the sliding direction of the steam rack 10 is... Figure 13 In the X-axis direction shown, the protrusions 151 are provided at both ends of the transition section 15 along the X-axis direction. Of course, in other embodiments, the transition section 15 can also be an arc segment. The arc segment allows for a smooth connection between the sliding surface 113 and the mating surface 121, so that the user can control the steam rack 10 to slide relative to the steam base 200 in the sliding direction, and also makes the user operation smoother.
[0073] As Figures 3 to 4 shown, the steamer 10 further comprises a handle assembly part 16 protruding from the side of the steamer 10. The handle assembly part 16 is used to mount the handle 30 to facilitate the user to control the steamer 10 to slide relative to the steam base 200 through the handle 30, and the handle 30 and the handle assembly part 16 are arranged in a split structure to facilitate the processing of the steamer 10. The handle 30 can be made of a material with low thermal conductivity, such as silicone rubber, to prevent the user from being scalded.
[0074] As Figure 1 shown, the utility model further provides an electric steamer, including steamer basket assembly 100, steam base 200 and cover 300, steam base 200 has support top surface 201, and steamer basket assembly 100 includes above-mentioned steamer 10. The steamer is arranged between steam base 200 and cover 300, and in the working state, the matching surface 121 is overlapped on the support top surface 201, and in the sliding state, the matching surface 121 and the sliding surface 113 are overlapped on the support top surface 201 together. Further, the steamer basket assembly 100 can further include the basket 20 and the handle 30, when only one layer of steamer 10 needs to be arranged, the cover 300 can be covered on the steamer 10, when multiple layers of steamer 10 need to be arranged, the basket 20 can be arranged on the bottom layer of steamer 10, and the second layer of steamer 10 can be arranged on the basket 20, and so on, finally, the cover 300 is covered on the top layer of steamer 10.
