Description

Technical Field

[0001] This utility model belongs to the field of cookware, specifically relating to a household anti-condensation steamer. Background Technology

[0002] Many household steamers on the market now offer steaming functions for staple foods, dishes, and reheating leftovers and side dishes. For example, when cooking porridge, placing steamed buns on the steamer rack allows for simultaneous cooking and heating of the buns, improving efficiency. However, during this process, the buns often become soggy, leading to a poor taste and even food waste. There are usually two reasons why the food becomes soggy: First, the water in the steamer evaporates when heated, producing a large amount of steam. This steam rises and condenses into water droplets when it encounters the cooler lid. These droplets usually fall onto the food due to gravity, causing it to become soggy. Second, water droplets fall through the gaps between the food placed on the steamer rack, accumulating and wetting the bottom of the food. This is especially true for steamed buns taken from the refrigerator for reheating. Because steamed buns taken from the refrigerator require a longer heating time to ensure even heating, more water accumulates on the steamer rack during this process, making the buns even more soggy and severely affecting their taste.

[0003] Chinese utility model patent CN207118836U discloses a steamer rack for preventing steam and water accumulation that can soak food. The technical solution is as follows: the steamer rack includes a conical inclined surface and a circular flat plate. The conical inclined surface is formed by the horizontal intersection of a conical surface and a horizontal plane. The inner edge of the top of the conical inclined surface is fixedly connected to the outer edge of the circular flat plate. Regular circular holes are provided on the conical inclined surface and the circular flat plate. Multiple guide grooves are provided on the conical inclined surface along its generatrix. A guide groove notch is formed at the intersection of the guide grooves and the outer edge of the bottom of the conical inclined surface, which can promptly drain the steam accumulated on the rack. The condensate drain is designed to prevent food on the grate from being soaked in water. However, this grate has several drawbacks. Drawback 1: When using the grate, food is placed on the conical inclined surface for heating. Due to the angle of the grate, the food is unstable. For example, soups placed on the grate are prone to tipping over. In addition, when removing the grate, food is more likely to fall into the pot. Drawback 2: Although there are multiple drainage grooves along the generatrix on the conical inclined surface of the grate to drain the condensate, its ability to prevent food from getting wet is limited. During the drainage process, the bottom of the food may still be in contact with the condensate, causing the food to become wet.

[0004] Chinese utility model patent CN204541788U discloses a drip-proof steamer lid. It features a sponge layer in the middle of the inner layer of the lid. This allows water vapor to absorb some of the condensation as it passes through the sponge, and a V-shaped groove guides the condensation on the sponge layer and the inner lid to a water reservoir, preventing it from accumulating on the inner lid and dripping. Absorbent cotton in the water reservoir absorbs the drained water, preventing accidental re-entry of water into the steamer when the lid is opened. While this lid effectively prevents condensation, it has drawbacks: the sponge layer is difficult to clean and prone to bacterial growth, especially in the humid environment of the steamer. Without proper cleaning and drying after use, bacteria can easily multiply, potentially contaminating food and causing diarrhea if ingested. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a household anti-condensation steamer. By circumferentially arranging drain support rods with their upper surfaces at the same horizontal plane on the conical grate, the food is placed on these rods during use. This ensures that the condensation flows along the conical slope while maintaining a horizontal food surface, guaranteeing food stability and preventing it from tipping into the steamer due to the grate's tilt during steaming or when removing the grate. Furthermore, the drain support rods prevent condensation from contacting the bottom of the food as it flows along the low-angle conical slope towards the edge, thus preventing food from spilling into the steamer. This design addresses the problem of food getting wet from contact with water. By incorporating a condensation groove on the pressure-relief condensation cover, with guide columns arranged around the lower circumference and condensation-promoting protrusions on the inner end face, and a pressure relief hole on the upper end of the cover, the design accelerates the condensation of water vapor into water droplets within the condensation groove on the lid. These droplets are then precisely guided to the water collection bowl via the guide columns. This utilizes physical flow guidance and collection principles to treat condensate, preventing it from dripping onto food and affecting its texture. It also avoids the bacterial growth of the sponge layer in a humid environment, as is present in existing technologies. This improves the cleanliness and safety of the steamer. The ingenious design offers advantages over existing technologies, including simple manufacturing, ease of use, and cleanliness.

[0006] The technical solution adopted by this utility model is: a household anti-condensation steamer, including a pot body, a pot lid, and a steam rack, with pot ears provided on both sides of the upper part of the pot body. The pot lid includes a lid body, a handle, and a water collection bowl. The lid body includes a first conical inclined surface and a pressure-relieving condensation cover integrally formed with the upper part of the first conical inclined surface. The pressure-relieving condensation cover is a cylindrical structure with a lid at the top and a hollow interior. A first screw hole is opened in the center of the lid at the top of the pressure-relieving condensation cover, and pressure relief holes are opened around the first screw hole. The hollow part inside the pressure-relieving condensation cover forms a condensation groove, and guide columns are arranged around the lower circumference of the condensation groove. The handle includes a grip, with a connecting part connected to the lower side of one end of the grip. A vertical screw is provided in the center of the lower end of the connecting part. The screw passes through the first screw hole in the center of the upper end of the pressure relief condensate cover to connect the cover body to the handle. A water collection bowl with an upward opening is connected to the lower part of the screw. The grate includes a conical grate body and drainage support rods. The conical inclined surface of the conical grate body has a generatrix that makes an angle of 1-3° with the horizontal plane. Drainage support rods are arranged in a circumferential array on the conical grate body, and the upper end faces of the drainage support rods are all on the same horizontal plane.

[0007] The end face inside the condensation tank is covered with condensation-promoting protrusions.

[0008] There are two pressure relief holes, which are centrally symmetrical to each other.

[0009] The water collecting bowl has a second screw hole in the center, and the water collecting bowl is connected to the lower part of the screw rod through the second screw hole. The lower end of the second screw hole is in a closed state.

[0010] The top of the drain support rod is rounded.

[0011] The comb is a single, integral structure.

[0012] The inner circumference of the pot body is provided with two extended support parts, and the inner diameter of the upper extended support part is larger than that of the lower extended support part.

[0013] The end of the guide column is inclined toward the center of the water collection bowl.

[0014] Beneficial effects: 1. By setting a conical grate with a generatrix angle of 1-3° to the horizontal plane, and arranging drain support rods with their upper surfaces on the same horizontal plane in a circumferential array around the conical grate, food placed on the drain support rods during steaming ensures that condensate flows along the conical slope while keeping the food surface horizontal, guaranteeing food stability and preventing food from tipping into the pot due to the grate's tilt during steaming or when removing the grate; 2. By setting the drain support rods, when food is placed on the drain support rods, the condensate on the grate flows along the low-angle conical slope to the edge, preventing condensate from contacting the bottom of the food, thus solving the problem of food... 3. By setting a condensation groove on the pressure relief condensation cover, with guide columns arranged around the lower circumference of the condensation groove and condensation-promoting protrusions laid on the inner end face, and a pressure relief hole opened on the upper end of the pressure relief condensation cover, the water vapor is accelerated to condense into water droplets in the condensation groove of the pot lid. The water is then precisely guided to the water collection bowl through the guide columns. This achieves the treatment of condensate water by using the principle of physical guidance and collection, avoiding condensate water from dripping from the pot lid onto the food and affecting the taste of the food. It also avoids the growth of bacteria in the sponge layer in the humid environment in the existing technology, improving the cleanliness and safety of the steamer. Its design is ingenious and has the advantages of simple manufacturing, convenient use, and cleanliness compared with the existing technology. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1-9 As shown, the technical solution adopted by this utility model is: a household anti-condensation steamer, including a pot body 1, a pot lid 2, and a rack 3. Pot ears 11 are provided on both sides of the upper part of the pot body 1. The pot lid 2 includes a lid body 21, a handle 22, and a water collection bowl 23. The lid body 21 includes a first conical inclined surface 211 and a pressure-relieving condensation cover 212 integrally formed with the upper part of the first conical inclined surface 211. The pressure-relieving condensation cover 212 is a cylindrical structure with a lid at the top and a hollow interior. A first screw hole 213 is opened in the center of the lid at the top of the pressure-relieving condensation cover 212, and pressure relief holes 214 are opened around the first screw hole 213. The hollow part inside the pressure-relieving condensation cover 212 forms a condensation groove 215, and guide columns 216 are arranged circumferentially at the lower end of the condensation groove 215. The handle 22 includes a grip 221. One end of the grip 221 is connected to a connecting part 222. A vertical screw 223 is provided at the center of the lower end of the connecting part 222. The screw 223 passes through the first screw hole 213 opened in the center of the upper end of the pressure relief condenser cover 212 to connect the cover 21 and the handle 22. A water collection bowl 23 with an upward opening is connected to the lower part of the screw 223. The grate 3 includes a conical grate body 31 and drain support rods 32. The conical inclined surface of the conical grate body 31 has a generatrix angle of 1-3° with the horizontal plane. The drain support rods 32 are arranged in a circumferential array on the conical grate body 31, and the upper end faces of the drain support rods 32 are all on the same horizontal plane. The principle is as follows: During steaming, the hot steam generated by the boiling water in the pot forms an upward airflow. Since the first conical inclined surface 211 of the cover body 21 and the pressure relief condensing cover 212 form the highest temperature gradient area in the pot, and the condensing groove 215 is located at the top of the pot body 1, away from the heat source at the bottom of the pot, the steam will naturally gather in the lower temperature upper part. At the same time, the air pressure inside the pot is higher than that outside, and the steam needs to be released through the pressure relief hole 214. The pressure relief hole 214 is located at the upper end of the pressure relief condensing cover 212, forming a pressure guiding path, so that the steam preferentially passes through the condensing groove 215 area to be discharged outside the pot. When the steam passes through the condensing groove 215, it comes into contact with the low temperature inner wall. The steam quickly condenses into water droplets. At this time, the circumferentially arranged guide columns 216 increase the contact area between the steam and the condensing surface, accelerating condensation. The condensed water droplets will flow along the surface of the guide columns 216 towards the water collection bowl 23, avoiding direct dripping onto the food surface. Due to the guiding effect of the pressure relief hole 214, the main steam flow is discharged through the condensation tank 215. Therefore, most of the condensed water is formed and collected in the condensation tank 215. Only a small amount of uncondensed steam may form water droplets in the first conical inclined surface 211 of the lid 21. The water droplets will slide down the edge of the inclined surface to the edge of the pot 1, rather than dripping onto the central food area. At the same time, the angle of the conical grate body 31 of the grate 3 is tilted so that the condensed water falling from the edge of the pot 1 onto the grate 3 flows to the edge. The upper end of the horizontally set drain support rod 32 ensures that the bottom of the food is isolated from the condensed water on the grate 3, forming a double anti-drip and anti-wetting effect between the lid 2 and the grate 3.

[0018] The end face inside the condensation tank 215 is provided with condensation-promoting protrusions 217. This setting increases the surface roughness and geometric curvature, providing nucleation sites for steam, reducing the energy barrier required for steam condensation, accelerating the rapid condensation of steam into fine droplets on the inner wall of the condensation tank 215, reducing the diffusion of uncondensed steam, and reducing the risk of water droplets falling onto food from the source. The setting of condensation-promoting protrusions 217 is conducive to the scientific rationality of this utility model. The condensation-promoting protrusions 217, the guide column 216 and the cover 21 are made of the same material and are integrally stamped, which is simple to manufacture, easy to clean, avoids the growth of bacteria, and ensures the stability and reliability of long-term use.

[0019] There are two pressure relief holes 214, which are symmetrical about each other. This arrangement ensures that the steam in the boiler is discharged evenly and stably. On the other hand, the symmetrically distributed pressure relief holes 214 can make the steam be subjected to balanced force as it rises to the condensation tank 215, pass through the condensation tank 215 area in an orderly manner and condense quickly, thereby improving the condensation efficiency and reducing the possibility of uncondensed steam overflowing from other positions to form water droplets.

[0020] The water collection bowl 23 has a second screw hole 231 in the center, which connects the water collection bowl 23 to the lower part of the screw rod 223. The lower end of the second screw hole 231 is closed. The second screw hole 231 in the center of the water collection bowl 23, connected to the lower part of the screw rod 223, ensures a stable connection between the water collection bowl 23 and the screw rod 223, preventing the water collection bowl 23 from shifting or falling off due to shaking during use, and ensuring its effective collection of condensate. The closed design of the lower end of the second screw hole 231 prevents the collected condensate from leaking back into the pot through the screw hole, and prevents water from entering the connection gap between the screw rod 223 and the screw hole, preventing the growth of dirt and affecting disassembly and cleaning. In addition, this structural design facilitates the installation and disassembly of the water collection bowl 23, and makes it easy to clean the water and impurities inside the water collection bowl 23 after use, ensuring the cleanliness and anti-condensation effect of the steamer for long-term use.

[0021] The top of the drain support rod 32 is rounded. This design can effectively prevent sharp edges from scratching hands or damaging the food surface when placing or picking up food, thus improving safety and convenience during use. On the other hand, the rounded corner design reduces the retention of condensate at the top of the support rod, allowing water to flow more smoothly along the rounded edge to the inclined surface of the grate 3, accelerating drainage efficiency and further reducing the possibility of the bottom of the food coming into contact with water.

[0022] The grate 3 is a one-piece structure; the one-piece molding of the grate 3 ensures the overall structural strength and stability of the grate 3. Secondly, the one-piece molding design avoids dirt and grime from accumulating in the gaps and reduces cleaning dead corners.

[0023] The inner circumference of the pot body 1 is provided with two extended support parts 12. The inner diameter of the upper extended support part 12 is larger than that of the lower extended support part 12. The extended support parts 12 are used to support the grates 3. The fact that the inner diameter of the upper extended support part 12 is larger than that of the lower extended support part 12 ensures that the two grates 3 can be smoothly put in and taken out when in use.

[0024] The end of the guide column 216 is inclined toward the center of the water collection bowl 23. This setting, through the design of the inclined angle, provides a clear centripetal flow path for the condensed water, so that the condensed water droplets can be more quickly and accurately gathered along the surface of the guide column 216 to the central area of ​​the water collection bowl 23, avoiding water droplet retention or splashing to the edge of the steamer due to the dispersion of the flow path, which is conducive to the scientific rationality of this utility model.

[0025] Specific working principle: During use, the screw 223 located at the center of the lower end of the connecting part 222 on the lower side of the handle 221 passes through the first screw hole 213 in the center of the upper end of the pressure relief condensation cover 212, connecting the cover 21 to the handle 22. The lower end of the screw 223 is fixedly connected to the second screw hole 231 of the water collection bowl 23, forming a detachable condensate collection structure. During steaming, the steam in the pot gathers towards the condensation groove 215 of the pot cover 2 due to the temperature gradient, and is accelerated to condense into condensate through the condensation-promoting protrusion 217. The guide column 216 guides the condensate to flow into the water collection bowl 23 along the circumference, preventing food from dripping. A small amount of water droplets condensed in the first conical inclined surface 211 slide down to the edge of the pot body 1. The conical grate body 31 of the grate 3, together with the horizontal drain support rod 32, isolates the bottom of the food from the accumulated water. After use, the water collection bowl 23 can be directly disassembled to pour out the condensate and clean, effectively solving the problem of food soaking, and taking into account both ease of operation and hygiene.
