The technical solutions of the embodiments of the present application are explained and described below in conjunction with the drawings of the embodiments of the present application, but the following embodiments are only preferred embodiments of the present application, and not all of them. Based on the examples in the implementation manners, other examples obtained by those skilled in the art without creative work shall fall within the protection scope of this application.

Example one:

1 and 2, the steam rice cooker with visible cooking proposed in the first embodiment of the present application includes a pot body 100, a pot cover 200, and an inner pot 300 contained in the pot body 100. The pot body 100 is provided with steam. The steam generated by the steam generator is passed into the inner container 300 for heating food. Specifically, the steam rice cooker of this embodiment has a split structure, that is, the cooker cover 200 can be detachably covered on the cooker body 100, which increases user convenience, such as facilitating the independent cleaning of the cooker cover 200. When the pot cover 200 is closed on the pot body 100, the pot cover 200 to the pot body 100 form a steam pipeline connecting the steam generator and the inner liner 300, and the steam generated by the steam generator is delivered to the inner liner 300 through the steam line Heat the food.

In order to enable the user to observe the cooking state of the food in the inner pot 300, the pot body 100 of this embodiment includes a base 120, a mounting frame 130, and an outer cover 110 installed therebetween. The base 120, the mounting frame 130 and the outer cover 110 surround In the accommodating cavity 1401, the outer cover 110 is provided with a first transparent window 1101 that can see through into the accommodating cavity 1401, and the inner container 300 is a transparent inner container and is placed in the accommodating cavity 1401. During cooking, the user can observe the cooking state of the food in the inner pot 300 from the side of the pot body 100 through the first transparent window 1101 on the outer cover 110, especially the bottom food that cannot be observed from the perspective of the pot cover 200, thereby enhancing the cooking experience.

In the above-mentioned steam rice cooker, the base 120 is the main load-bearing part of the cooker body 100. To support the outer cover 110 and the inner liner 300 to ensure the structural strength of the whole machine. The mounting frame 130 prevents the lid 200 from being directly pressed on the outer cover 110 when the lid 200 is closed, so as to better protect the outer cover 110. Since the base 120, the mounting frame 130 and the outer cover 110 are all independent components, there are more choices in product design. For example, the thickness of the outer cover 110 and the mounting frame 130 can be adjusted according to actual needs, and the two do not affect each other. The base 120, the mounting frame 130, and the outer cover 110 can also be made of different materials according to actual needs, so as to better meet the product modeling requirements.

In this embodiment, the base 120 includes a base body 121 and a column 122 extending upward from the base body 121. The base body 121 and the column 122 are integrally formed to improve the structural strength of the base 120. The outer cover 110 is supported on the base body 121 and connected with the pillar 122 to form a circumferentially closed structure. The circumferential closed structure ensures the integrity of the circumferential appearance of the pot body 100 and reduces the heat loss of the inner pot 300. The outer cover 110 with the first transparent window 1101 is relatively weak. The connection of the outer cover 110 and the column 122 can ensure that the circumferentially closed structure still has enough strength to support the pot cover 200, preventing the outer cover 110 from bearing the full weight of the pot cover 200. Deformation risk. Illustratively, the base body 121 is provided with a positioning groove 124 matching the outer cover 110, and the bottom of the outer cover 110 is inserted into the positioning groove 124. For example, if the outer cover 110 is in the shape of an arc as a whole, the positioning groove 124 is also set in an arc shape that matches the outer cover 110. Both ends of the positioning groove 124 extend to the uprights 122. The two circumferential ends of 110 are matched with the uprights 122 to circumferentially close the accommodating cavity 1401, that is, the above-mentioned circumferential closed structure. In the above example, the mating fit of the base body 121 and the outer cover 110 facilitates the disassembly and assembly between the two, and can avoid the problem of warping of the bottom of the outer cover 110.

Further, the outer cover 110 is provided with limit hooks 111 at both ends in the circumferential direction, the column 122 is provided with a limit card slot 123 corresponding to the limit hook 111, and the limit hook 111 is inserted into the limit hook from top to bottom. Position the card slot 123. Exemplarily, the limit hook 111 and the limit card slot 123 are in an L shape that cooperates with each other, the limit hook 111 is provided on the upper part of the two circumferential ends of the outer cover 110, and the limit card slot 123 is provided at the two ends of the column 122 in the circumferential direction. Upper part. When the outer cover 110 and the base 120 are assembled, the installation position of the outer cover 110 is determined by the cooperation of the limit hook 111 and the limit slot 123, and then the bottom of the outer cover 110 is inserted into the positioning slot 124. After the assembly is completed, the limit hook 111 is inserted into the limit card slot 123 to limit the relative movement of the outer cover 110 and the column 122 in the circumferential direction, so as to avoid warping deformation of the end of the outer cover 110 and the assembly gap change caused by the warping deformation. Big problem. Of course, this assembly structure facilitates the disassembly and assembly of the outer cover 110 and the base 120. In other embodiments, the outer cover 110 can also be fixed on the base 120 by connecting methods such as screws and buckles.

With reference to FIG. 3, in this embodiment, the mounting bracket 130 covers the upper end of the outer cover 110 and the upper end of the column 122, and the outer cover 110 and the column 122 jointly support the mounting bracket 130. When assembling, you can connect the mounting frame 130 and the outer cover 110 to the base 120 as a whole, or you can first assemble the outer cover 110 and the base 120, and finally install the mounting frame 130, but no matter which installation method is required to ensure that the outer cover 110 and the base 120 The column 122 can support the mounting frame 130 at the same time, so that the mounting frame 130 can be effectively supported throughout the entire circumference, so that the pressure applied to the mounting frame 130 when the lid 200 is closed is transmitted to the outer cover 110 and the column 122, respectively, to prevent the mounting frame 130 from being affected. The uneven force increases the risk of deformation, and it also prevents the outer cover 110 from bearing the full weight of the pot cover 200 to increase the risk of deformation.

In an implementation of this embodiment, the first transparent window 1101 is arranged along the entire circumference of the outer cover 110. For example, as shown in FIG. 4, the outer cover 110 is an arc-shaped structure with a central angle α, and the first transparent window is also an arc-shaped structure with a central angle α on the outer cover 110, making full use of the space of the outer cover 110 and expanding the first transparent window. The visible area of the transparent window achieves the effect that the outer cover 110 is visible all around. Preferably, the outer cover 110 is a transparent piece, such as a transparent glass piece, and the outer cover 110 as a whole constitutes the first A transparent window 1101 maximizes the first transparent window 1101 on the outer cover 110, and enhances the user's cooking visual experience and product aesthetics.

It should be noted that the outer cover 110 described in the present application is provided with a first transparent window 1101. The outer cover 110 may partially constitute the first transparent window 1101. For example, the outer cover 110 is assembled from a transparent cover body and a non-transparent cover body or is injection molded into an integrated structure. The transparent cover body forms the first transparent window 1101; it is also possible that the outer cover 110 completely constitutes the first transparent window 1101, for example, the outer cover 110 is entirely made of a transparent material.

In this embodiment, when the outer cover 110 completely constitutes the first transparent window, the mounting frame 130 may also be a transparent piece. In this way, in the appearance of the pot body 100, the mounting frame 130 and the outer cover 110 have an integrated visual effect, which not only increases the visible area of the pot body 100, but also makes the shape of the pot body 100 more beautiful.

Further, referring to FIGS. 1 and 2, the first transparent window 1101 of this embodiment includes a window body 103 and at least two reinforcing ribs 112 arranged circumferentially on the inner circumferential surface of the window body 103 to improve the support strength of the window body 103 , So that the window body 103 can be made larger and thinner while reducing the risk of deformation and cracking. The window body 103 is divided into the main viewing zone 113 and the extended viewing zone 114 located on both sides of the main viewing zone 113 by the above-mentioned at least two reinforcing ribs 112. The side surface of the base 120 is provided with an operation panel 126 corresponding to the position of the main viewing area 113. The main viewing area 113 has the largest viewing area and there is no visual interference from the ribs 112. When the operation panel 126 on the side of the base 120 is set corresponding to the main viewing area 113, the user needs to perform cooking operations at the position facing the main viewing area 113. During operation, the cooking status of the food in the inner tank 300 can be observed through the main viewing area 113, which not only obtains a good operation and visual experience, but also reduces the probability of misoperation; the extended viewing area 114 on both sides of the main viewing area 113 increases The overall viewing area of the window body 103 is increased to realize multi-angle visibility in the circumferential direction of the pot body 100.

During cooking, the user can observe the cooking state of the food in the inner pot from the side of the pot body through the first transparent window on the outer cover, especially the bottom food that cannot be observed from the perspective of the pot lid, thereby enhancing the cooking experience.

By expanding the area of the first transparent window and reducing the thickness of the first transparent window, a larger viewing area and a clearer visual experience can be obtained, but the strength of the first transparent window will also be weakened due to ordinary impact and pressure. All may cause the first transparent window to deform or even break. In this embodiment, at least two reinforcing ribs 112 are provided on the window body 103 of the first transparent window 1101 to increase the support strength of the window body, so that the window body can be made larger and thinner while reducing the risk of deformation and cracking.

Since the arrangement of the stiffener 112 will obstruct the line of sight and affect the visual effect, in this embodiment, the window body 103 is separated by at least two stiffeners 112 into the main viewing area and the extended viewing area located on both sides of the main viewing area. The main viewing area has The largest viewing area without the visual interference of the rib 112. When the operating panel on the side of the base is set to correspond to the main viewing area, the user needs to perform cooking operations at the position facing the main viewing area, and the main viewing area can also be used while operating Observing the cooking state of the food in the inner tank not only obtains a good operation and visual experience, but also reduces the chance of misoperation; the extended viewing area on both sides of the main viewing area increases the overall viewing area of the window body, and realizes the circumferential direction of the pot body. Visual angle.

Further, the reinforcing rib 112 of this embodiment has a connecting portion 116 extending from the bottom end of the window body 103, and the connecting portion 116 is fixedly connected to the base 120. The connecting portion 116 is provided to facilitate the installation and fixation of the first transparent window 1101 on the base 120, and the connecting portion 116 is arranged on the reinforcing rib 112 to avoid damage to the window body when the first transparent window 1101 is disassembled and assembled. Illustratively, the base A positioning hole is provided in the positioning groove 124 of the main body 121. When the bottom of the first transparent window 1101 is inserted into the positioning groove, the connecting portion 116 is inserted into the positioning hole. The window 1101 is fixed on the base 120.

Referring to FIGS. 1-2 and 6, the first transparent window 1101 further includes a supporting platform 117 extending from the top of the window body 103 toward the center of the accommodating cavity 1401, and the mounting frame 130 bears a load on the supporting platform 117. The supporting platform 117 increases the load-bearing area of the first transparent window 1101 to the mounting frame 130 and reduces the force on the window body 103. Preferably, the thickness of the supporting platform 117 decreases in its extending direction. For example, referring to FIG. 6, the upper surface of the supporting platform 117 is kept level, and the lower surface of the supporting platform 117 is from the root position (that is, the supporting platform 117 is from the upper end of the window body 103). The starting position extending toward the center of the accommodating cavity 1401) is inclined from low to high toward the free end to form a triangular support structure to increase the support strength of the support platform 117, especially the strength of the root position of the support platform 117, so as to avoid the root position The stress concentration causes the support platform 117 to deform.

2, in this embodiment, a pair of handles 310 are provided on the upper end of the side wall of the inner tank 300, and the mounting frame 130 is provided with a handle groove 131 for placing the handles 310. When the inner tank 300 is placed in the accommodating cavity 1401, the mounting frame 130 supports The handle 310 keeps the inner container 300 in a suspended state, and therefore, the position of the window body 103 corresponding to the handle groove 131 is subjected to greater pressure than other parts. To this end, a reinforcing rib c and a reinforcing rib d are provided on the window body 103 at positions corresponding to the handle groove 131. The area between the reinforcing rib c and the reinforcing rib d on the window body 103 corresponds to a central angle of 180°, and the reinforcing rib c The and reinforcing ribs d are located directly below the corresponding handle groove 131 to avoid local deformation of the window body 103 due to excessive force. The base 120 includes an inner liner heat-insulating seat 1201 and a base shell 1202 arranged around the inner liner heat-insulating seat 1201. The inner liner 300 does not contact the outer cover 110 and the base 120. A gap is provided between the bottom of the inner liner 300 and the inner liner heat-insulating seat 1201. The temperature resistance of the seat 1201 material is required. In other embodiments, the bottom of the inner liner can also be supported on the inner liner heat-insulating seat. The inner liner heat-insulating seat and the base shell are integrally formed with good load-bearing capacity. When the inner liner heat-insulating seat supports the bottom of the inner liner, The bile is placed more smoothly.

1 and 2, the pot cover 200 covers the pot body 100 and defines a cooking cavity with the inner pot 300. The pot body 100 is provided with a steam generator for supplying steam to the cooking cavity, and the inner pot 300 is a transparent inner pot. The pot body 100 is provided with a first transparent window 1101. In one embodiment, the pot cover 200 is provided with a second transparent window 210, and the light entering the cooking cavity from the first transparent window 1101 and the second transparent window 210 complement each other, so as to better pass through the first transparent window 1101 or the second transparent window 1101 or the second transparent window 210. The transparent window 210 observes the cooking state in the cooking cavity.

This application completely uses steam heating, which is different from the non-steam heating in the prior art. From the beginning of the application, there is a large amount of hot steam in the cooking cavity. The diffuse steam causes a large number of water droplets to adhere to the first transparent window, affecting Visual effects. For this reason, a second transparent window is provided on the lid. Although the second transparent window will affect the visual effect due to the diffuse steam at the beginning, it is liquefied on the first transparent window and the second transparent window. Small water droplets can transmit light, so compared to only the first transparent window, the amount of light transmitted is increased. Therefore, light can be supplemented by visible windows in different directions to reduce the impact of steam on visual effects. The complementary light can also overcome the problem of poor visual effects in different placement environments. When the pot body is placed normally, the front side (i.e. front) and top side (i.e. top surface) of the pot body are facing the user, the back side (i.e. back) generally faces away from the user, and the left and right sides (i.e. side) are located on the left and right sides of the user. When one side of the pot body is in a low-light environment, such as the back side facing the stove or wall, the top side facing the cabinet, or the left and right sides facing the wall, etc., this can be done through the first and second transparent windows The light is supplemented to improve the visual effect. In this way, it can ensure that no matter from which angle the inner tank is viewed, the other The outside window can be supplemented with light to avoid the situation where the cooking state in the inner tank is not clearly seen.

As shown in Figure 1, the second transparent window 210 is provided with a first light-transmitting area 211 and a second light-transmitting area 212. As for a part of the main viewing area, the second light-transmitting area is set close to the left or right side or the left and right sides of the pot body, that is, it is set on the pot cover close to the part of the extended viewing zone. By setting the first light-transmitting area, the light irradiated from above the front side of the pot cover can be obtained as much as possible to illuminate the cooking cavity; at the same time, by setting the second light-transmitting area, the light from the pot can be obtained as much as possible. The light from the upper left and right side of the lid; while the back side of the body of the steam rice cooker is usually placed toward the wall, so the part of the lid near the back is darker, and the part of the lid near the back fills in light. It can be ignored, and it can be decided whether to set the light-transmitting area in this part according to the actual situation. In this way, the light in the front direction acquired by the first transparent window is added to realize the mutual complement of the light, so that the user can observe the cooking cavity from any side, and the visual effect is better.

The first transparent window includes a main viewing zone 113 and an extended viewing zone 114 located on both sides of the main viewing zone, and the visible area of the main viewing zone is larger than the visible area of the extended viewing zone. The first transparent window is located on the front side of the pot body, and when the pot body is placed normally, the front side is mostly an open space, which is not easy to be blocked, so it has a greater effect of supplementing light. In order to further improve the effect of light supplementation, an extended viewing area is set to improve the viewing angle effect under different viewing angles.

In this embodiment, the pot body 100 includes a base 120 and an outer cover 110. The base 120 and the outer cover 110 enclose a accommodating cavity 1401 for accommodating the inner liner 300, and the outer cover 110 partially or entirely constitutes the first transparent window 1101, which is designed in this way, The outer cover 110 not only constitutes a part of the outer appearance surface of the pot body 100 in the circumferential direction, but also constitutes a part or all of the first transparent window 1101, which simplifies the structure of the pot body 100 and reduces the cost. In this embodiment, the pot body 100 is also provided with a water tank for supplying water to the steam generator 150. The base body 121 supports the water tank 150, and the side of the water tank 150 is hung on the column 122 for fixing.

It should be noted that when the outer cover 110 partially constitutes the first transparent window 1101, the outer cover 110 can be assembled from a transparent cover body and a non-transparent cover body or injection molded into an integral structure, for example, a mounting hole is provided on the non-transparent cover body, and the transparent cover body The body is assembled in the mounting hole to form a first transparent window 1101; when the outer cover 110 completely constitutes the first transparent window 1101, the outer cover 110 is entirely made of a transparent material.

In this embodiment, when the second transparent window 210 is provided on the pot cover 200, all the flat parts of the pot cover 200 can be made into the second transparent window 210 to achieve the effect that the top is visible all around, or it can be the pot cover 200. A mounting hole is provided, and a transparent material is assembled in the mounting hole to form a second transparent window 210. The second transparent window 210 may have a single-layer structure or a multi-layer composite structure of two or more layers.

According to the steam rice cooker of this embodiment, the first transparent window 1101 provided on the body 100 allows the user to observe the cooking state of the food in the cooking cavity from the side of the body 100, especially the bottom food that cannot be observed from the top view angle. The second transparent window 210 provided on the cooker cover 200 allows the user to observe the cooking state of the food surface in the cooking cavity from the top of the cooker body 100, thereby achieving the visual effect of multi-angle cooking on the top and sides of the steam rice cooker. On this basis, the light entering the cooking cavity by the first transparent window 1101 and the second transparent window 210 complement each other, which can enhance the visual effect. Specifically, if only the second transparent window 210 is provided on the pot cover 200, when the user observes through the second transparent window 210, the cooking state of the food in the cooking cavity may not be clearly seen due to insufficient light, reflection of the window, etc., but when When the pot body 100 is provided with the first transparent window 1101, the light from the first transparent window 1101 entering the cooking cavity is used as a supplement to make the cooking cavity Have better visual conditions and improve visual effects. The same is true when the user observes through the first transparent window 1101.

180°，即，第一透明視窗1101在周向方向上覆蓋煲體100的角度大於等於180°。如圖4所示，本實施例的外罩110呈圓弧形，當外罩110部分或者全部構成第一透明視窗1101時，第一透明視窗1101亦為圓弧形，可視角度α即為第一透明視窗1101對應於外罩110所在圓周圓心的圓心角。當第一透明視窗1101在煲體100周向方向上的可視角度α

180°時，煲體100側部在周向方向上獲得更廣泛的視覺角度，由於內膽300大都為圓筒形，當用戶在第一透明視窗1101正中位置觀察時，烹飪腔的可視區域也達到了180°，周向方向上沒有視覺盲區。更優選地，可視角度α為200°~260°，當可視角度α超過260°時，外罩110強度偏低，受衝擊或者受熱容易變形，為了兼顧到視覺化和機械強度，故限定可視角度α為200°~260°，可選地，α為200°、210°、220°、230°、240°、250°、260°。 In order to enhance the visual effect, in this embodiment, the visual angle α of the first transparent window 1101 in the circumferential direction of the pot body 100 is

180°, that is, the angle at which the first transparent window 1101 covers the pot body 100 in the circumferential direction is greater than or equal to 180°. As shown in FIG. 4, the outer cover 110 of this embodiment is in the shape of an arc. When the outer cover 110 partially or completely constitutes the first transparent window 1101, the first transparent window 1101 is also in the shape of an arc, and the viewing angle α is the first transparent window. The window 1101 corresponds to the central angle of the center of the circumference where the outer cover 110 is located. When the viewing angle α of the first transparent window 1101 in the circumferential direction of the pot body 100

At 180°, the side of the pot body 100 obtains a wider visual angle in the circumferential direction. Since the inner pot 300 is mostly cylindrical, when the user observes at the center of the first transparent window 1101, the visible area of the cooking cavity is also Reaching 180°, there is no blind spot in the circumferential direction. More preferably, the viewing angle α is 200°~260°. When the viewing angle α exceeds 260°, the outer cover 110 has low strength and is easily deformed by impact or heat. In order to take into account the visual and mechanical strength, the viewing angle α is limited. It is 200°~260°, optionally, α is 200°, 210°, 220°, 230°, 240°, 250°, 260°.

Exemplarily, referring to FIG. 4, the window body 103 is an arc-shaped structure with a central angle α greater than 180°, and the side of the pot body 100 has a wider viewing angle in the circumferential direction, which can further expand the main viewing area 113 It has a viewing area and can extend the extended viewing area 114 to opposite sides of the pot body 100. The user can also observe the cooking state of the food in the inner pot 300 on the opposite sides of the pot body 100. The inner circumferential surface of the window body 103 is provided with ribs 112 at intervals in the circumferential direction. The ribs 112 include at least rib a and rib b. The area between the rib a and the rib b on the window body 103 is the main viewing area 113 , The window body 103 is located between the reinforcing rib a and the left end of the window body 103 The area in between is the extended viewing zone 114 on the left, and the area on the window body 103 between the rib b and the right end of the window body 103 is the extended viewing zone 114 on the right. The reinforcing rib a and the reinforcing rib b extend vertically from the top end of the window body 103 to the bottom end of the window body 103. When the window body 103 bears the load, the direction of the force is consistent with the height direction of the window body 103, and the reinforcing rib 112 is formed by the window body 103 The top end vertically extends to the bottom end of the window body 103, so that the window body 103 can be effectively supported by the reinforcing rib 112 in the height direction.

In this embodiment, the central angle β of the main viewing zone 113 is 90°~180°. When the central angle β of the main viewing area 113 is less than 90°, the viewing area of the main viewing area 113 is too small, and it is easy to be interfered by the above-mentioned reinforcing ribs a and b. When the central angle β of the main viewing area 113 is greater than 180°, strengthen Rib a and rib b are too far apart, weakening the support strength of the main viewing area 113, so the central angle β of the main viewing area 113 is limited to 90°~180°, and the optional central angle β is 90°, 100°, 110 °, 120°, 150°, 160°, 180°.

Of course, the present application is not limited to the foregoing embodiments. In other embodiments, more reinforcing ribs can be provided according to the size of the visible area of the first transparent window and the support strength requirements.

10-12, in this embodiment, the first transparent window 1101 extends symmetrically to both sides of the pot body 100 at the center of the front side of the pot body 100. When the user observes the front side of the pot body 100, the first transparent window 1101 The visible areas of the areas on both sides of the pot body 100 are the same, achieving a good symmetrical vision, and the pot body 100 also has a left-right symmetrical appearance.

2 and 10, in an implementation of this embodiment, the first transparent window is arranged around the liner and the first transparent window 1101 is within the height range of the liner 300, and the horizontal projection of the first transparent window 1101 is all located at On the side of the inner pot 300, the visible area defined by the first transparent window 1101 is concentrated on the side of the inner pot 300 to prevent other devices inside the pot body 100 from being exposed The first transparent window 1101 affects the visual effect. Exemplarily, the base body 121 is provided with a groove 125 matching the bottom of the inner liner 300, and the bottom of the inner liner 300 sinks into the groove 125, so that the inner liner 300 is placed on the base 120 more stably. Wherein, the first transparent window is arranged around the inner liner, and the first transparent window may surround the entire inner liner circumferentially, or it may be a part of the first transparent window circumferentially surrounding the inner liner. Specifically, that the first transparent window 1101 is within the height range of the inner container 300 means that the bottom wall of the inner container 300 is lower than the lower edge of the first transparent window 1101, and the mouth of the inner container 300 is higher than the upper edge of the first transparent window 1101 . In this way, when the user is observing at the side position of the pot body 100, the cooking state of the food in the inner container 300 can be observed by looking up or down the first transparent window 1101.

L

2/3H。這裡的可視距離L對於圓形的第一透明視窗而言即為第一透明視窗的直徑，對於矩形的第一透明視窗而言即為第一透明視窗的高度，當可視距離L不足煲體100高度H的1/3時，煲體100側部形成的可視區域過於狹窄，不利於用戶觀察，且對第二透明視窗210的補光效果也大幅削弱；當可視距離L超過煲體100高度H的2/3時，不僅煲體100結構強度得不到保證，而且留給煲體100安裝其他器件的空間高度不足，需要增加煲體100體積。 In this embodiment, the visible distance of the first transparent window 1101 in the height direction of the pot body 100 is L, and the height of the pot body 100 is H, 1/3H

L

2/3H. The visible distance L here is the diameter of the first transparent window for the circular first transparent window, and the height of the first transparent window for the rectangular first transparent window. When the visible distance L is less than 100 When the height H is 1/3, the visible area formed by the side of the pot body 100 is too narrow, which is not conducive to user observation, and the supplementary light effect of the second transparent window 210 is also greatly weakened; when the visible distance L exceeds the height H of the pot body 100 2/3 of the time, not only the structural strength of the pot body 100 cannot be guaranteed, but also the height of the space left for the pot body 100 to install other devices is insufficient, and the volume of the pot body 100 needs to be increased.

2, in an implementation of this embodiment, the pot cover 200 includes a transparent cover 220 (for example, a glass cover, a transparent plastic cover, etc.) and a decorative cover 230. The decorative cover 230 is usually made of a non-transparent material. And it surrounds the edge of the transparent cover 220 for protecting the transparent cover 220, and the exposed part of the transparent cover 220 constitutes the second transparent window 210. This design greatly increases the visible area of the pot cover 200, and achieves the visual effect of the pot cover 200 throughout the entire week. Accordingly, the user can observe the cooking state of more food in the cooking cavity through the second transparent window 210, which improves Improve the user’s cooking visual experience.

Referring to Figures 1-2 and 5, in an implementation of this embodiment, the boiler body 100 is also provided with a steam output pipe 410 connected to the steam generator 400, and the boiler cover 200 is provided with a steam input pipe 250, when When the pot cover 200 is closed on the pot body 100, the steam output line 410 and the steam input line 250 are connected, and the steam generated by the steam generator 400 is delivered to the inner liner 300 through the steam output line 410 and the steam input line 250 Heat food in medium. Further, the center of the pot cover 200 is also provided with an air inlet channel communicating with the cooking cavity, and the steam input pipeline 250 on the pot lid 200 is in communication with the air inlet channel.

Since the steam input pipe 250 and the air intake passage are both within the visible range of the transparent cover 220, in order to avoid the steam pipe and the air intake passage from being exposed, the decorative cover 230 is provided with a shielding portion 231 extending toward the center of the pot cover 200 to block The part 231 covers the transparent cover 220 to shield the steam pipeline. A handle 240 is installed in the center of the pot cover 200 to block the air inlet channel and facilitate the user to take and place the pot cover.

In this embodiment, the base 120 is the main load-bearing component of the pot body 100, which directly or indirectly supports structural components such as the outer cover 110 and the inner liner 300, and ensures the structural strength of the whole machine. The inner tank heat insulation seat 1201 and the base shell 1202 adopt an integrated structure, which increases the load-bearing capacity of the base 120 and improves the structural strength of the whole machine. Exemplarily, the base shell 1202 includes an annular shell 1203 arranged around the inner insulation seat 1201 and an upright body extending upward from one side of the annular shell 1203. The housing 1204 and the outer cover 110 are supported on the annular housing 1203 and connected with the upright housing 1204 to form a circumferentially closed structure. The circumferential closed structure ensures the integrity of the circumferential appearance of the pot body 100, and reduces the heat loss of the inner pot 300; the outer cover 110 with a transparent window is relatively weak, and the outer cover 110 and the upright shell 1204 are connected to ensure circumferential sealing The structure still has enough strength to support the pot cover 200 to prevent the outer cover 110 from bearing the full weight of the pot cover 200 and increase the risk of deformation.

When the steam rice cooker is cooking, since the inner insulation seat 1201 is located under the inner pot 300, the inner insulation seat 1201 insulates the heat radiation from the bottom of the inner pot 300 to the inner space of the base 120, effectively alleviating the radiation temperature rise in the inner space of the base 120, The electronic devices (such as circuit boards, etc.) in the base 120 are prevented from working in a high temperature environment for a long time, and the working safety and service life of the electronic devices are increased.

5, in this embodiment, since the outer cover 110 is provided with a transparent window, in order to prevent other devices in the pot body 100 from being exposed in the transparent window and affecting the visual effect, these devices can be installed inside the base 120, for example, a steam generator 400 is arranged in the annular shell 1203, and the steam output pipeline 410 is arranged in the vertical shell 1204, which not only prevents the steam generator 400 and the steam output pipeline 410 from being exposed in the transparent window of the outer cover 110, but also reduces steam The heat loss when passing through the steam output line 410.

Embodiment two:

The arrangement of the water tank 150 makes full use of the circumference of the cooker body 100. To space, the water tank 150 is used as a water storage container, and also used to form the outer appearance of the pot body 100, so that the water tank 150 obtains a larger water storage space without increasing the volume of the pot body, which is suitable for steam cooking. At the same time, the middle ring and other structural parts of the shell of the pot in the prior art can be omitted, the structure of the pot can be simplified, and the cost can be reduced.

Since the water tank 150 is arranged around the inner tank 300, the heat emitted from the inner tank 300 can be used by the water tank 150, that is, the heat emitted from the inner tank preheats the water in the water tank 150 and raises the initial temperature of the water in the water tank 150. This speeds up the steam generation efficiency and saves energy. Since the water in the water tank 150 absorbs most of the heat, it is equivalent to setting up a heat insulation layer between the inner tank and the outer side wall 151 of the water tank. It extends the life of the water tank 150 and has a better anti-scalding effect.

The water tank 150 of this embodiment has a non-closed ring structure, such as a C-shaped structure.

Preferably, the water tank 150 is provided with a second relief portion 154 that cooperates with the second upright 1222, and the second relief portion 154 is formed by a recessed inner side wall 152 of the water tank. The cooperation here can be understood as the second upright 1222 is fully or partially embedded in the second giving way portion 154, which weakens the influence of the second upright 1222 on the appearance of the pot body 100, and serves to position the water tank 150 during the assembly and use of the water tank 150. The role of.

In an implementation of this embodiment, the pot lid is buckled on the water tank with the lid closed. For example, a fixed buckle that can be buckled with the movable buckle is provided on the upper end of the inner side wall of the water tank, so that the pot lid can be directly buckled. On the water tank, no additional buckling structure is needed on the base.

One end of the steam guide pipe is connected to the steam input pipeline, and the other end extends into the cooking cavity to send steam into the food so that the steam can be Fully contact with the food material, the heat effect of the food material is better.

The long steam flow path and the unstable air outlet speed of the steam generator 400 will make the steam in the steam pipeline appear pulsating, and the transient steam pressure may be too high to lift the lid 200 and destroy the steam output pipeline 410 In the connection state with the steam input pipe 250, air leakage occurs, and the steam delivered to the cooking cavity will also have irregular pulse jets, which affects the cooking quality.

With reference to Figures 17 and 18, in view of the above problems, the present embodiment is provided with a first bending section on the steam input pipeline 250, and the first bending section changes the steam flow direction to buffer the impact of the steam flow. More specifically, when the pulsed steam passes through the first bending section, the steam flow rate is reduced due to the change of the steam flow direction, which effectively alleviates the pulsation of the steam flow, so that the steam input pipe 250 delivers steam to the cooking cavity stably and continuously; The reduction of the steam flow rate also reduces the pressure fluctuations in the steam input pipeline 250, and avoids the problem of steam leakage caused by the instantaneous high pressure that causes the lid 200 to be lifted up.

Preferably, the steam input pipeline 250 of this embodiment includes an air delivery channel 251, an air inlet channel 252 communicating with the cooking cavity, and a docking channel 253 for connecting the steam output pipeline 410. The connecting part and the connecting part of the gas transmission channel 251 and the docking channel 253 respectively form a first bending section. When the steam is introduced into the cooking cavity from the steam input pipe 250, it undergoes two changes and buffers, so that the steam originally flowing from the pot body 100 to the pot cover 200 The flow is folded back to the direction of the pot body 100 to realize the steam delivery to the cooking cavity. The two buffering can enhance the stability and continuity of the steam flow without excessively reducing the steam flow rate and pressure, which is conducive to the rapid and uniform steam in the cooking cavity. To spread.

Exemplarily, an air inlet connector 170 is provided in the center of the pot lid 200, and a butt joint 158 is provided on one side of the pot lid 200.

The side wall of the butt joint 158 has a first interface 254 extending outward, and the bottom of the butt joint 158 is provided with a second interface 255. When the lid 200 is closed, the second interface 255 communicates with the steam output pipe 410. The air inlet connector 170 includes an upper connector 430 and a lower connector 440 connected to each other. The side wall of the upper connector 430 is provided with an upper interface 431, and the bottom of the lower connector 440 is provided with a lower interface 441. The docking joint 158 defines a docking passage 253, the upper joint 430 and the lower joint 440 are connected to define an air inlet passage 252, and two ends of the first connecting tube 160 are respectively inserted into the first interface 254 and the upper interface 431 to define the air delivery passage 251.

It should be understood that this embodiment is not limited to the above exemplary solutions. In other embodiments, bending one end or both ends of the first connecting pipe can also form the first bending section.

Preferably, the air intake passage 252 is orthogonally communicated with the air conveying passage 251, and the docking passage 253 is orthogonally communicated with the air conveying passage 251. Specifically, the center axis of the first interface 254 is perpendicular to the center axis of the butt joint 158, the center axis of the upper interface 431 is perpendicular to the center axis of the upper joint 430, and the center axis of the butt joint 158 and the center axis of the air inlet joint are vertical. State, the central axis of the first connecting pipe 160 is in a horizontal state, and the two first bending sections between the air inlet passage 252 and the air passage 251 and between the docking passage 253 and the air passage 251 can all achieve 90° bends. The fold can not only effectively buffer the steam flow, but also reduce the height requirement for the installation space inside the pot cover 200, and facilitate the installation of the steam input pipeline 250.

17 and 18, preferably, the cross-sectional area of the air inlet passage 252 is larger than the cross-sectional area of the air delivery passage 251 (for example, the inner diameter D1 of the upper joint 430> the inner diameter D2 of the upper interface 431), and the cross-sectional area of the docking passage 253 is larger than the steam output The cross-sectional area of the pipeline 410 (for example, the inner diameter D3 of the butt joint 158> the diameter D4 of the steam output pipeline 410). The steam flow rate and pressure in the steam input pipe 250 will change with the cross-sectional area of the steam input pipe 250. Since the cross-sectional area of the air inlet passage 252 is larger than the cross-sectional area of the air delivery channel 251, when When the steam enters the intake passage 252, the sudden increase of the cross-sectional area will reduce the steam flow rate and pressure, that is, enhance the buffering effect of the first bending section on the pulsed air flow. The same is true when steam enters the docking channel 253 from the steam input line 250.

Further, referring to Figures 15-17, the steam output pipe 410 is provided with a second bending section. The second bending section buffers the impact of the steam flow by changing the steam flow direction, so that the pulsed flow can be obtained before entering the pot cover 200 Effective buffering, further smoothing pressure fluctuations and stabilizing steam flow rate.

Preferably, the steam output pipeline 410 includes a transverse passage 450 communicating with the steam generator 400 and a vertical passage 460 communicating with the transverse passage 450, and the connecting portion between the transverse passage 450 and the vertical passage 460 forms a second bending section. In this embodiment, the air outlet 420 of the steam generator 400 is arranged horizontally, and the steam flow direction is changed through the steam output pipe 410, and the steam is delivered to the steam input pipe 250 while buffering the steam flow. Exemplarily, an air outlet connector 470 is provided on the pot body 100, and the air outlet connector 470 is connected to the air outlet 420 of the steam generator 400 through a second connecting pipe 161 to define a steam output pipeline 410.
