Electric rice cooker capable of adding trace elements

Abstract

This utility model discloses a rice cooker capable of adding trace elements, relating to the field of kitchen appliances. It includes a pot body, an inner pot within the pot body, and an upper lid covering the pot body. The upper lid has an adding device with a holding chamber connected to the inner pot, allowing steam to flow back into the inner pot. Because the upper lid has the adding device, and the holding chamber contains trace element materials and is connected to the inner pot, when the rice cooker is cooking, the steam generated evaporates upwards from the inner pot, enters the holding chamber, and comes into contact with the trace element materials. This causes the trace elements to dissolve in the steam, which then condenses into water droplets at the adding device and falls into the food inside the inner pot, thus achieving the function of adding trace elements to the food.

Description

Technical Field

[0001] This utility model relates to the field of kitchen appliances, and in particular to a rice cooker that can add trace elements. Background Technology

[0002] As living standards improve, people are paying more and more attention to their health. Although the human body requires very small amounts (usually less than 100 mg / day), trace elements play an irreplaceable and crucial role in maintaining life activities, promoting growth and development, and ensuring health. They mainly function as cofactors of enzymes, components of hormones, or participate in key physiological processes. However, ordinary foods contain very little of these trace elements, which is insufficient to meet the body's needs. Therefore, adding trace elements to food is a good option to meet the body's requirements.

[0003] Existing rice cookers do not have the function of adding trace elements to food, which cannot meet user needs. Utility Model Content

[0004] This invention addresses the problem that existing rice cookers cannot add trace elements and thus fail to meet user needs by providing a rice cooker that allows for the addition of trace elements.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An electric rice cooker that can add trace elements includes a pot body, an inner pot disposed in the pot body, and an upper cover disposed on the pot body. The upper cover is provided with an adding device, and the adding device has a holding cavity. The holding cavity is connected to the inner pot and allows water vapor to flow back into the inner pot through the holding cavity.

[0007] As described above, the rice cooker that can add trace elements includes a food container cover, an inner cover on the side of the upper cover near the inner pot, and a fixing part on the inner cover for fixing the food container cover.

[0008] As described above, in a rice cooker that allows the addition of trace elements, one of the fixing part and the food container cover is provided with a boss, and the other part is provided with a groove that cooperates with and is fixed to the boss.

[0009] The fixing part is a disc body, and the protrusions are distributed in a ring along the inner side wall of the disc body. The side wall of the material holding cover is provided with a groove corresponding to the protrusions. The protrusions and the grooves cooperate to fix the material holding cover to the inner cover.

[0010] As described above, in a rice cooker that allows the addition of trace elements, the inner wall of the fixing part is provided with a first threaded part, and the side wall of the food container is provided with a second threaded part that cooperates with and is fixed to the first threaded part.

[0011] As described above, the rice cooker that can add trace elements has multiple L-shaped mounting grooves surrounding the inner side wall of the fixing part, and multiple protruding posts on the side wall of the food container that cooperate with and are fixed to the L-shaped mounting grooves. The L-shaped mounting grooves are perpendicular to the inner cover and have an entry end and a locking end. The protruding posts enter the L-shaped mounting grooves from the entry end, so that the locking end cooperates with the protruding posts to lock them.

[0012] As described above, in a rice cooker that can add trace elements, the inner wall of the fixed part is provided with a plurality of raised strips, and the side wall of the food container is provided with a plurality of raised points that abut against the plurality of raised strips. The raised strips are provided with an inclined end and a limiting end. When the food container rotates relative to the fixed part, the raised points move from the inclined end to the limiting end, so that the raised strips and the raised points cooperate to lock the food container.

[0013] As described above, in a rice cooker that allows the addition of trace elements, the side wall of the food container is provided with a through hole that connects the inner pot to the food container cavity.

[0014] As described above, in a rice cooker that allows the addition of trace elements, a sealing ring is provided around the inner lid. When the inner lid is placed over the inner pot, the sealing ring and the inner lid work together to seal the inner pot.

[0015] As described above, in a rice cooker that allows the addition of trace elements, a cover is provided between the fixing part and the food container to isolate the trace element material.

[0016] Compared with existing technologies, the beneficial effects of this technical solution are as follows:

[0017] With the structure of this utility model, since the top cover is equipped with an adding device, and the adding device has a holding cavity, which holds trace element materials and is connected to the inner pot, when the rice cooker is cooking food, the water vapor generated evaporates upward from the inner pot and enters the holding cavity, and comes into contact with the trace element materials, so that the trace elements dissolve in the water vapor. The water vapor is finally condensed into water droplets in the adding device and falls into the food in the inner pot, thereby realizing the function of adding trace elements to the food.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] like Figures 1 to 4The rice cooker shown includes a pot body 1, an inner pot 11 disposed within the pot body 1, and an upper lid 12 covering the pot body 1. The upper lid 12 is equipped with an adding device 2, which has a holding chamber 21 connected to the inner pot 11, allowing steam to flow back into the inner pot 11. Because the upper lid 12 has the adding device 2, which contains the holding chamber 21, and the holding chamber 21 holds trace element materials and is connected to the inner pot 11, when the rice cooker is cooking, the steam generated evaporates upwards from the inner pot 11, enters the holding chamber 21, and comes into contact with the trace element materials. This causes the trace elements to dissolve in the steam, which then condenses into water droplets at the adding device 2 and falls into the food inside the inner pot 11, thus achieving the function of adding trace elements to the food. (See reference) Figure 1 Arrow a indicates the direction of water vapor evaporation, and arrow b indicates the direction of water droplet falling. Trace element materials may contain elements such as iron, zinc, iodine, selenium, copper, fluorine, chromium, and molybdenum.

[0029] As a specific implementation and not a limitation, in order to allow water vapor to better contact with the trace element material in the adding device 2, the adding device 2 includes a material holding cover 22. An inner cover 13 for sealing the inner liner 11 is provided on the side of the upper cover 12 near the inner liner 11. The inner cover 13 has a fixing part 3 for fixing the material holding cover 22. Because the inner cover 13 has the fixing part 3 for fixing the material holding cover 22, when the upper cover 12 is closed, the adding device 2 is positioned above the inner liner 11, allowing water vapor to better contact with the trace element material in the adding device 2, and the formed water droplets to drip more effectively into the inner liner 11.

[0030] Furthermore, in order to achieve communication between the material holding cavity 21 and the inner liner 11, the side wall of the material holding cover 22 is provided with through holes 221 that connect the inner liner 11 and the material holding cavity 21. The side wall of the material holding cover 22 is provided with multiple through holes 221, which can be of any shape, so that the material holding cavity 21 can communicate with the inner liner 11, and water vapor can easily enter the material holding cavity 21 through the through holes 221 and come into contact with the trace element materials.

[0031] As a specific implementation method and not a limitation, in order to better lock in water vapor and prevent water vapor leakage when cooking food, the inner cover 13 is provided with a sealing ring 131 around its periphery. When the inner cover 13 is placed on the inner pot 11, the sealing ring 131 and the inner cover 13 cooperate to seal the inner pot 11. The sealing ring 131 is made of food-grade silicone. Because this type of sealing ring 131 is relatively soft, when the upper cover 12 is closed, the upper cover 12 drives the inner cover 13 to fit against the inner pot 11. The sealing ring 131 seals the gap between the inner cover 13 and the inner pot 11, thereby achieving a seal on the inner pot 11. This makes it difficult for water vapor to leak during cooking, prevents moisture loss, and also provides a better heat preservation effect.

[0032] Furthermore, the fixing part 3, the inner cover 13, and the material holding cover 22 together form the material holding cavity 21.

[0033] Furthermore, to prevent the trace element material from directly contacting the fixing part 3 and forming an independent unit, thus avoiding any residue of the trace element material on the fixing part 3, a cover 23 for isolating the trace element material is provided between the fixing part 3 and the holding cover 22. This cover 23 is a cover with a diameter slightly smaller than that of the holding cover 22. When placing the trace element material, the trace element material is placed in the holding cover 22, then the cover 23 is placed on top of the trace element material, and finally the holding cover 22 is fixed to the fixing part 3, completing the placement of the trace element material. Since the cover 23 is placed on top of the trace element material, it isolates the trace element material from the fixing part 3, forming an independent unit and preventing any residue of the trace element material from remaining on the fixing part 3.

[0034] As a specific implementation and not a limitation, in order to install the adding device 2 on the inner cover 13, one of the fixing part 3 and the material holding cover 22 is provided with multiple protrusions 34, and the other part is provided with multiple grooves 32 that cooperate and fix with the multiple protrusions 34. The fixing part 3 is a disc body, and the multiple protrusions 34 are distributed in a ring along the inner side wall of the disc body. The multiple protrusions 34 and the multiple grooves 32 are correspondingly matched to fix the material holding cover 22 on the inner cover 13. The side wall of the disc body may be provided with more than two protrusions 34, and the side wall of the material holding cover 22 is provided with grooves 32 corresponding to the protrusions 34. When it is necessary to install the adding device 2, the grooves 32 on the material holding cover 22 are aligned with the protrusions 34, and the material holding cover 22 is rotated so that the protrusions 34 are engaged in the grooves 32, thereby realizing the installation of the adding device 2. When it is necessary to remove the adding device 2, it is only necessary to rotate the material holding cover 22 so that the protrusions 34 are disengaged from the grooves 32, and the material holding cover 22 can be removed from the fixing part 3. Installation and disassembly are very convenient. In addition, the side wall of the fixing part 3 can be provided with a groove 32, and the material cover 22 is provided with a boss 34 corresponding to the groove 32.

[0035] Example 2:

[0036] Reference Figure 5 As shown, the main difference between this embodiment and Embodiment 1 is that the side wall of the fixing part 3 is provided with a first threaded part 31, and the side wall of the material holding cover 22 is provided with a second threaded part 33 that cooperates with and is fixed to the first threaded part 31. The fixing part 3 is a disc body, and the side of the disc body is provided with the first threaded part 31. By twisting the material holding cover 22, the second threaded part 33 on the side wall of the material holding cover 22 is tightened with the first threaded part 31, thereby fixing the adding device 2.

[0037] Example 3:

[0038] The main difference between this embodiment and Embodiment 1 is that the inner wall of the fixing part 3 is provided with multiple L-shaped mounting grooves, and the side wall of the material holding cover 22 is provided with multiple protruding posts that cooperate and fix with the multiple L-shaped mounting grooves. The L-shaped mounting grooves are perpendicular to the inner cover 13. The L-shaped mounting grooves have an entry end and a locking end. The protruding posts enter the L-shaped mounting grooves from the entry end, so that the locking end cooperates with the protruding posts to lock them. The L-shaped mounting grooves have an entry end and a locking end. When installation is required, the L-shaped mounting grooves are aligned with the protruding posts, and the material holding cover 22 is twisted so that the protruding posts enter the L-shaped mounting grooves from the entry end and finally reach the locking end of the L-shaped mounting grooves, so that the locking end cooperates with the protruding posts to lock them, thereby realizing the installation of the adding device 2 on the inner cover 13.

[0039] Example 4:

[0040] Reference Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that a plurality of protrusions 35 are arranged around the inner sidewall of the fixing part 3, and a plurality of protrusions 36 abutting against the plurality of protrusions 35 are provided on the sidewall of the material holding cover 22. The protrusions 35 are provided with an inclined end 351 and a limiting end 352. When the material holding cover 22 rotates relative to the fixing part 3, the protrusions 36 move from the inclined end 351 to the limiting end 352, so that the protrusions 35 and the protrusions 36 cooperate to lock the material holding cover 22. In this embodiment, multiple protrusions 35 and protrusions 36 are provided. The protrusions 35 are provided with an inclined end 351 and a limiting end 352. When it is necessary to fix the material container 22, the protrusions 36 are aligned with the protrusions 35, and the material container 22 is rotated so that the protrusions 36 abut against the protrusions 35 and move from the inclined end 351 of the protrusions 35 to the limiting end 352, and finally limit it at the limiting end 352, thereby realizing that the protrusions 35 and the protrusions 36 cooperate to fix the material container 22 on the fixing part 3.

[0041] The specific working principle of this utility model is as follows:

[0042] The inner cover 13 is equipped with an additive device 2. When the rice cooker is cooking food, the water vapor generated will evaporate upwards and enter the additive device 2. The trace element material in the additive device 2 will dissolve in the water vapor. Then, the water vapor will condense into water droplets at the bottom of the additive device 2. Due to gravity, the water droplets will eventually drip into the food in the inner pot 11, thus adding trace elements to the food. When it is not necessary to add trace elements, simply remove the food cover 22 and take out the trace element material.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
