Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils, specifically to an electric rice cooker. Background Technology

[0002] A rice cooker is a modern kitchen appliance primarily used for cooking rice, but it also has multiple cooking functions such as making porridge, stewing soup, and steaming vegetables. Through its built-in heating element and intelligent control system, the rice cooker precisely controls the temperature and time, thus producing delicious and nutritious rice.

[0003] To prevent internal components from having a shortened lifespan due to high temperatures, rice cookers are usually equipped with cooling components such as cooling fans. The rice cooker also has an air intake to introduce external cold air. The fan drives the external cold air to flow in a specific direction, so that the cold air covers the heating elements and carries away the heat, thus achieving heat dissipation.

[0004] When a rice cooker is in use, particles such as oil fumes and dust in the kitchen environment can easily enter with the airflow and block the air intake, affecting heat dissipation. However, the air intake of rice cookers in the current technology is not easy to clean, which leads to a decrease in heat dissipation performance. Utility Model Content

[0005] This utility model aims to solve one of the technical problems in related technologies to a certain extent. Therefore, this utility model provides a rice cooker with the advantage of easy maintenance and cleaning of the air intake.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An electric rice cooker includes a cooker body, the cooker body including an outer shell and an air intake and a mounting groove disposed at the bottom of the outer shell, a filter cover being slidably and detachably connected in the mounting groove, the filter cover covering the air intake.

[0007] In this application, the air intake is located at the bottom of the outer casing. Since kitchen fumes, water vapor, and other pollutants typically rise (due to the principle of hot air rising), placing the air intake at the bottom reduces the probability of pollutants directly entering, thus extending the cleaning cycle of the filter cover. Furthermore, the air intake at the bottom of the casing can be concealed by cabinets or countertops, reducing visual interference, improving the overall aesthetics of the product, and also reducing the risk of accidental contact by children (such as inserting fingers into the air intake). In related technologies, the air intake of rice cookers is often a fixed structure that is difficult to disassemble, or a detachable structure that requires flipping the rice cooker to access the air intake. This application, however, includes a filter cover to conceal the air intake. The filter cover acts as a physical barrier, intercepting particulate matter such as fumes and dust in the kitchen environment, preventing them from directly accumulating at the air intake and in the internal air duct. Additionally, the filter cover can be detachably connected to the mounting slot by sliding laterally. Users can easily install and remove the filter cover by pushing and pulling it, without the need for tools or complex operations. Compared to the fixed air intake or the design that requires flipping the product to remove the air intake in related technologies, users can quickly remove and install the filter cover without moving or flipping the rice cooker, thereby achieving the purpose of maintaining the cleanliness of the air intake and improving the convenience of cleaning and maintenance.

[0008] Optionally, the mounting groove extends laterally to the sidewall of the housing and has an opening on the sidewall of the housing.

[0009] The opening provides a passage for inserting and removing the filter cover. Users can push the filter cover into the mounting slot or pull it out through the opening on the side wall. In addition, the opening is located on the side wall of the housing, so the filter cover can be operated without flipping the housing, enabling quick removal and installation of the filter cover and facilitating the cleaning of the intake port.

[0010] Optionally, the width of the mounting groove decreases from the side of the opening to the side away from the opening, and the width of the filter cover is adapted to the mounting groove.

[0011] When the filter cover is inserted into the mounting slot from the opening, the gradually decreasing width of the mounting slot guides the filter cover's movement, making it easier to reach the intended installation position, thus serving a positioning function. Therefore, when installing the filter cover, users do not need to precisely align each position of the mounting slot; they only need to roughly align the filter cover with the opening and then push it in along the decreasing width of the mounting slot, reducing the difficulty of installation and improving installation efficiency.

[0012] Optionally, the filter cover includes a shielding portion, which shields the opening when the filter cover is installed in the mounting groove.

[0013] The shielding prevents external dust and fumes from entering the housing through the opening, protecting the internal components and extending the equipment's lifespan.

[0014] Optionally, the filter cover further includes a filter section and connecting sections on both sides of the filter section. The filter section covers the air intake, and the connecting sections are slidably connected to the side wall of the mounting groove. The filter section has a concave portion, which is recessed from the bottom surface upwards.

[0015] The filter section can partially intercept dust, grease, and other contaminants, thus preventing blockage of the air intake and protecting the internal components from contamination. Additionally, the recessed design allows users to apply force when removing or installing the filter cover, facilitating lateral sliding operations.

[0016] Optionally, the filter cover is tightly fitted to the mounting groove, and the side wall of the mounting groove is provided with a sliding groove adapted to the connecting part. The sliding groove extends downward at an angle from the opening side to the side away from the opening.

[0017] The groove on the side wall of the mounting slot provides a sliding track for the connection part of the filter cover. That is, the groove can guide the connection part to slide along a predetermined path so that the filter cover can be smoothly installed into the mounting slot, reducing the difficulty of alignment during installation and improving the efficiency and accuracy of installation.

[0018] Optionally, the housing has a front side and a rear side that are arranged opposite to each other, and the bottom of the housing is provided with a power supply slot for installing a power supply. The power supply slot is located near the rear side, and the mounting slot is located near the front side. The opening of the mounting slot faces the front side, left side, or right side of the housing.

[0019] By placing the power supply slot near the rear and the mounting slot near the front, the functions of the power module and the filter cover are separated, preventing interference between them. This design makes full use of the housing space, placing the power supply and filter cover in suitable positions, thus improving the overall space utilization of the housing.

[0020] Optionally, one of the outer shell and the filter cover is provided with a buckle, and the other is provided with a claw. When the filter cover is installed in the mounting groove, the claw engages with the buckle.

[0021] When the filter cover is installed into the mounting slot, the claws and buckles engage, and the physical fit between them restricts the movement of the filter cover, securing it to the housing and preventing it from detaching. Furthermore, the structure of the claws and buckles is relatively simple, thus reducing production costs.

[0022] Optionally, the mounting groove has a groove opening and a bottom wall opposite to the groove opening, the air intake is located on the bottom wall, and the filter cover covers the groove opening to shield the air intake.

[0023] The air intake is placed on the bottom wall of the mounting slot, and the filter cover covers the slot opening to shield the bottom wall and the air intake on the bottom wall, thereby preventing external dust, debris, flying insects and other foreign objects from entering the air intake and avoiding foreign objects from clogging the air intake.

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0028] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this patent. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0029] Example: like Figures 1 to 3As shown, this embodiment provides a rice cooker, including a cooker body, the cooker body including an outer shell and an air intake 11 and a mounting groove 12 disposed at the bottom of the outer shell 1. A filter cover 2 is slidably connected to the mounting groove 12 and covers the air intake 11.

[0030] In this embodiment, the outer casing 1 is used to house internal components (such as heating plates, circuit boards, etc.), and a cooling component such as a cooling fan is disposed inside the outer casing 1 to dissipate heat from the internal components. Additionally, the bottom of the outer casing 1 is provided with a mounting groove 12 and an air intake 11 for introducing external cold air. The mounting groove 12 is located at the bottom of the outer casing 1 and is integrally formed with the outer casing 1, while the air intake 11 is distributed within the mounting groove 12. Specifically, the air intake 11 is constructed as multiple elongated small holes. In other embodiments, the air intake 11 can also be constructed as a single larger hole, as long as it achieves the purpose of air intake. Of course, in other embodiments, the shape of the air intake 11 can be circular, irregular, etc. The mounting groove 12 is used to install a filter cover 2, which can intercept dust, fumes, and other particulate matter, preventing them from directly depositing on the air intake 11 and the internal air duct. The filter cover 2 can be detachably connected to the mounting groove 12 by sliding laterally, that is, the filter cover 2 can be laterally slid to selectively cover or expose the air intake 11. Users can quickly install and remove the filter cover 2 simply by pushing and pulling it horizontally, without the need for tools or complicated operations.

[0031] When the rice cooker is running, internal components (such as the heating plate) generate heat, causing the internal temperature of the outer casing 1 to rise. At this time, the cooling fan starts, drawing in cool outside air through the air intake 11. As the cool air passes through the filter cover 2, dust, oil fumes, and other particulate matter are intercepted by the filter cover 2, allowing relatively clean air to enter the interior of the outer casing 1. After absorbing heat from the internal components, the clean air is exhausted from the outer casing 1, thus achieving heat dissipation.

[0032] The mounting groove 12 extends laterally to the side wall of the housing 1 and has an opening 13 on the side wall of the housing 1.

[0033] Specifically, the filter cover 2 can be slidably switched between an installation position that shields the air intake 11 and a replacement position that exposes the air intake 11. In this embodiment, the mounting groove 12 extends laterally to the side wall of the housing 1. That is, the mounting groove 12 is not arranged along the vertical direction (such as the up-down direction) of the housing 1, but extends along the horizontal direction (assuming the housing 1 is normally placed in the left-right direction), so that the mounting groove 12 can accommodate the laterally sliding filter cover 2, providing space for the installation of the filter cover 2 inside the housing 1. An opening 13 is provided on the side wall of the housing 1, so that the filter cover 2 can enter the mounting groove 12 through the opening 13, which facilitates the installation, removal and subsequent maintenance of the filter cover 2. The shape of the opening 13 should be adapted to the filter cover 2 so that the filter cover 2 can pass smoothly through the opening 13. Specifically, the opening 13 provides a channel for the insertion and removal of the filter cover 2. When the filter cover 2 needs to be installed into the mounting slot 12, the user can push the filter cover 2 into the mounting slot 12 through the opening 13 on the side wall, at which point the filter cover 2 is in the installation position. Similarly, when the filter cover 2 needs to be removed, it can be easily pulled out from the opening 13, at which point the filter cover 2 is in the replacement position. Since the opening 13 is located on the side wall of the outer shell 1, the filter cover 2 can be operated without flipping the outer shell 1, realizing quick removal and installation of the filter cover 2, thereby achieving the purpose of maintaining the cleanliness of the air intake 11 and improving the convenience of cleaning and maintenance. In other embodiments, when the filter cover 2 slides laterally to the replacement position, the filter cover 2 can also move downward to disengage from the mounting slot 12.

[0034] The width of the mounting groove 12 decreases from the side of the opening 13 toward the side away from the opening 13, and the width of the filter cover 2 is adapted to the mounting groove 12.

[0035] In this embodiment, the width direction of the mounting groove 12 refers to the direction perpendicular to the central axis of the mounting groove 12, that is, the direction perpendicular to the opening 13 of the mounting groove 12. Furthermore, within the plane containing the mounting groove 12 and the filter cover 2, the width direction of the mounting groove 12 is perpendicular to the direction of movement of the filter cover 2 during installation or removal. The mounting groove 12 is generally trapezoidal in shape, with its width decreasing from the side with the opening 13 towards the side away from the opening 13. The filter cover 2 is also generally trapezoidal in shape and is adapted to the mounting groove 12. When the filter cover 2 is inserted into the mounting groove 12 from the opening 13, the gradually decreasing width of the mounting groove 12 guides the filter cover 2, making it easier to reach the predetermined installation position, thus serving a positioning function. Additionally, as the filter cover 2 penetrates deeper into the mounting groove 12, the gradually narrowing mounting groove 12 more firmly fixes the filter cover 2 within the mounting groove 12, preventing it from loosening or falling off.

[0036] The filter cover 2 includes a shielding part 21. When the filter cover 2 is installed in the mounting groove 12, the shielding part 21 shields the opening 13.

[0037] In this embodiment, the shielding part 21 is the portion of the filter cover 2 used to shield the opening 13 of the mounting groove 12, and its shape and size must be adapted to the opening 13. In this embodiment, the opening 13 is constructed in an arc shape, so the shielding part 21 is also constructed in an arc shape. In other embodiments, the opening 13 can also be constructed in a straight line. The user aligns the shielding part 21 of the filter cover 2 with the opening 13, and then pushes the filter cover 2 to slide laterally within the mounting groove 12. As the width of the mounting groove 12 decreases, the filter cover 2 is gradually squeezed by the side wall of the mounting groove 12 during the sliding process. When it slides to the appropriate position, a tight fit is formed between the filter cover 2 and the mounting groove 12, achieving fixation.

[0038] The filter cover 2 also includes a filter section 22 and a connecting section 23 provided on both sides of the filter section 22. The filter section 22 covers the air intake 11. The connecting section 23 is slidably connected to the side wall of the mounting groove 12. The filter section 22 is provided with a concave section 24, which is recessed from the bottom surface upward.

[0039] In this embodiment, the filter section 22 has several vent holes, the diameter of which is much smaller than that of the air intake 11, so as to block dust and other particulate matter without affecting the introduction of external cold air. When air passes through the filter section 22, dust, oil fumes, etc. are partially intercepted by the filter section 22, thereby achieving the purpose of purifying the air and protecting the internal components of the outer casing 1 from contamination. The connecting part 23 is provided on both sides of the filter section 22, and the connecting part 23 is slidably connected to the side wall of the mounting groove 12, which guides the filter cover 2 to slide laterally in the mounting groove 12, so that the filter cover 2 can be smoothly installed in the installation position or moved to the replacement position, while ensuring the stability of the filter cover 2 after installation. The recessed part 24 is formed on the filter section 22. On the one hand, the recessed part 24 forms a certain space, which makes it easy for the user to apply force when disassembling or installing the filter cover 2. For example, the user can hook the edge of the recessed part 24 with their fingers or tools to facilitate lateral sliding. On the other hand, the recessed structure can increase the structural strength of the filter cover 2 to a certain extent, making it less prone to deformation when subjected to external forces.

[0040] The filter cover 2 is tightly connected to the mounting groove 12. The side wall of the mounting groove 12 is provided with a sliding groove 121 that is adapted to the connecting part 23. The sliding groove 121 extends downward from the side of the opening 13 to the side away from the opening 13.

[0041] In this embodiment, the groove 121 on the side wall of the mounting groove 12 provides a sliding track for the connecting part 23 of the filter cover 2. Since the groove 121 extends downwards at an angle from the side of the opening 13 towards the side away from the opening 13, i.e., the groove 121 is constructed at an angle and the side with the opening 13 is higher than the side away from the opening 13, after the filter cover 2 is installed, the side closer to the opening 13 is also higher than the side away from the opening 13, thus preventing the filter cover 2 from detaching from the mounting groove 12 under gravity. Furthermore, the angled groove 121 provides a clear installation direction for the filter cover 2. When the filter cover 2 is installed at an angle, the angled surface of the groove 121 can guide the connecting part 23 to slide along a predetermined path, reducing the difficulty of alignment during installation. The user does not need to precisely adjust the horizontal position of the filter cover 2; they only need to roughly align it with the groove 121. Relying on the guiding effect of the angled groove 121, the connecting part 23 can smoothly slide into the groove 121, improving the efficiency and accuracy of installation. In other embodiments, the height of the side of the groove 121 closer to the opening 13 and the height of the side away from the opening 13 can also be flush.

[0042] The housing 1 has a front side and a rear side that are arranged opposite to each other. The bottom of the housing 1 is provided with a power supply slot 14 for installing a power supply. The power supply slot 14 is located near the rear side, and the mounting slot 12 is located near the front side. The opening 13 of the mounting slot 12 faces the front side, left side, or right side of the housing 1.

[0043] In this embodiment, the power supply slot 14 is placed near the rear, and the mounting slot 12 is placed near the front, to achieve functional separation between the power supply module and the filter cover 2 and to avoid interference between the power supply and the filter cover 2. The power supply, as the power source of the device, requires a relatively independent environment to reduce the impact of external interference on its normal operation. The filter cover 2, on the other hand, typically requires frequent installation, removal, and maintenance depending on actual usage; placing it on the front makes operation easier. In this embodiment, the opening 13 of the mounting slot 12 faces forward to avoid interference between the filter cover 2 and the power supply during installation and maintenance. In other embodiments, the opening 13 of the mounting slot 12 may also face to the left or right; this is not a limitation.

[0044] like Figure 4 As shown, one of the outer shell 1 and the filter cover 2 is provided with a buckle, and the other is provided with a claw. When the filter cover 2 is installed in the mounting groove 12, the claw and the buckle are engaged.

[0045] In this embodiment, a buckle is provided on the outer shell 1, and a claw is provided on the filter cover 2. When the filter cover 2 is installed into the mounting groove 12, the claw engages with the buckle to fix the filter cover 2 to the outer shell 1, preventing the filter cover 2 from falling off. It should be noted that the buckle or claw can be located within the mounting groove 12 of the outer shell 1, or elsewhere on the outer shell 1, as long as it can secure the filter cover 2. In other embodiments, claws can also be provided on the outer shell 1, and buckles on the filter cover 2. The buckle and claw have a certain anti-detachment capability after engagement. For example, the edge of the buckle can be designed as a bevel or arc to match the shape of the claw, increasing the firmness of the engagement and preventing the filter cover 2 from loosening or falling off due to vibration or other reasons during use. The structure of the buckle and claw is a conventional technical means, as long as it enables a detachable connection between the outer shell 1 and the filter cover 2, and will not be elaborated further here.

[0046] The mounting slot 12 has a slot and a bottom wall opposite to the slot. The air intake 11 is located on the bottom wall, and the filter cover 2 covers the slot to shield the air intake 11.

[0047] In this embodiment, the mounting groove 12 has an opening and a bottom wall opposite to the opening. The opening is the inlet for external air to enter the interior of the mounting groove 12. The air intake 11 is located on the bottom wall of the mounting groove 12, and the filter cover 2 is installed at the opening to cover the air intake 11. In other embodiments, the air intake 11 can also be located outside the mounting groove 12, as long as the filter cover 2 can cover the air intake 11 when installed at the bottom of the outer casing 1. For example, the filter cover 2 has wings on its side, and when the filter cover 2 is installed in the mounting groove 12, the wings cover the air intake 11.

[0048] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
