Description

Technical Field

[0001] This utility model belongs to the field of rice steamer technology, specifically relating to an energy-saving rice steamer. Background Technology

[0002] A rice steamer is a kitchen appliance specifically designed for steaming rice or other foods. Rice steamers are widely used in homes, restaurants, canteens, and other places, and are favored by users because of their ease of operation and good steaming effect.

[0003] Existing energy-saving rice steamers typically have multiple insulation layers installed in their interlayer to improve heat preservation and reduce heat loss, thereby achieving energy saving. Although multiple insulation layers can improve heat preservation, in actual operation, the heat preservation effect of relying solely on the insulation layer is still limited. The high-temperature steam released by the pressure relief valve contains a large amount of heat energy, but this steam cannot be effectively reused, resulting in energy waste. When only a small amount of food needs to be steamed, the entire rice steamer needs to be filled with steam, which is not only time-consuming and energy-intensive, but also cannot effectively achieve the effect of energy saving. Utility Model Content

[0004] In view of this, the present invention provides an energy-saving rice steamer, which can improve the heat preservation effect of the steamer by working together with the energy-saving insulation mechanism and the partition component, and make the insulation cavity a steam insulation barrier. By collecting and reusing the high-temperature steam released by the pressure relief valve, the heat preservation effect of the steamer is significantly improved, energy waste is reduced, and the entire rice steamer does not need to be filled with steam, thus achieving the purpose of high efficiency and energy saving.

[0005] To address the aforementioned technical problems, this utility model provides an energy-saving rice steamer, comprising a steamer and a pressure relief valve located at the top of the steamer. The steamer is equipped with an energy-saving insulation mechanism for collecting the high-temperature steam released from the pressure relief valve. The energy-saving insulation mechanism includes an insulation chamber within the steamer, a steam collection hood at the top of the steamer, the pressure relief valve located within the steam collection hood, a transmission pipe on the outer arc surface of the pressure relief valve, and an insulation pipe within the insulation chamber. The exhaust end of the transmission pipe penetrates the inner wall of the insulation chamber and connects to the insulation pipe. The exhaust ends of the insulation pipe penetrate the lower ends of both sides of the steamer and extend to the outside. The steamer also includes a partition component, which improves the insulation effect of the steamer and makes the insulation chamber a steam insulation barrier. By collecting and reusing the high-temperature steam released from the pressure relief valve, the insulation effect of the steamer is significantly improved, reducing energy waste. It eliminates the need to fill the entire rice steamer with steam, achieving high efficiency and energy saving.

[0006] The insulation pipes are distributed in a serpentine pattern on the wall surface of the insulation cavity near the inner cavity of the steam chamber, which increases the heat release area during steam recovery.

[0007] The partition assembly includes a partition plate that can be inserted into the steamer. The middle opening of the partition plate is internally threaded with a connecting pipe head one, and the lower end of the pressure relief valve is threaded with a connecting pipe head two. A high-temperature resistant pipe is provided between the connecting pipe head two and the connecting pipe head one, so that the entire rice steamer does not need to be filled with steam, thus achieving the purpose of high efficiency and energy saving.

[0008] The partition assembly also includes multiple mounting slots respectively located on the left and right sides of the steam oven cavity. The two ends of the partition plate are movably connected to the adjacent mounting slots on the same side, thus providing support for the partition plate and its auxiliary mechanisms.

[0009] The partition assembly also includes an insulation board set inside the partition plate, which further improves the heat preservation effect of the steam oven.

[0010] The wall surface of the insulation cavity near the inner cavity of the steamer is provided with grooves that are compatible with the insulation pipes, thereby improving the efficiency and effect of heat exchange.

[0011] High-temperature resistant pipes are high-temperature resistant corrugated expansion joints, which can maintain good flexibility and sealing performance in high-temperature environments.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. The steamer generates a large amount of steam during operation. The steam cooks the food inside the steamer, and the pressure inside the steamer gradually increases. Once a certain value is reached, the pressure relief valve automatically opens, releasing excess high-temperature steam to ensure that the internal pressure of the steamer is within a safe range. The released high-temperature steam enters the steam collection hood and is guided through the transmission pipe on the steam collection hood to the insulation pipe in the insulation cavity. The insulation pipe is distributed in a serpentine pattern on the wall of the insulation cavity near the inner cavity of the steamer, increasing the heat dissipation area. The high-temperature steam flows in the insulation pipe and exchanges heat with the air inside the steamer, improving the insulation effect of the steamer and making the insulation cavity a steam insulation barrier, thus achieving the purpose of energy saving in the rice steamer. By collecting and reusing the high-temperature steam released by the pressure relief valve, the insulation effect of the steamer is significantly improved, and energy waste is reduced.

[0014] 2. When only a small amount of food needs to be steamed, the baffle plate can be inserted into a set of mounting slots at the corresponding height. Then, the first connecting pipe end is threaded to the baffle plate, and the second connecting pipe end is threaded to the pressure relief valve. This reduces the steaming area, allowing for quick steaming of that portion of the food without filling the entire steamer with steam, achieving high efficiency and energy saving. The baffle plate is equipped with an insulation board, further improving the heat preservation effect of the steamer. The high-temperature resistant pipe is a high-temperature resistant corrugated expansion pipe, which can maintain good flexibility and sealing performance in high-temperature environments, ensuring the reliability of steam transmission.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides an energy-saving rice steamer, such as... Figure 1-5 As shown: It includes a steam chamber 100 and a pressure relief valve 200 disposed on the upper end of the steam chamber 100. The steam chamber 100 is equipped with an energy-saving heat preservation mechanism, which is used to collect the high-temperature steam released by the pressure relief valve 200. The energy-saving heat preservation mechanism includes a heat preservation cavity 300 disposed in the steam chamber 100. A gas collection hood 301 is disposed at the upper end of the steam chamber 100. The pressure relief valve 200 is located in the gas collection hood 301. A transmission pipe 302 is disposed on the outer arc surface of the pressure relief valve 200. A heat preservation pipe 303 is disposed in the heat preservation cavity 300. The exhaust end of the transmission pipe 302 penetrates the inner wall of the heat preservation cavity 300 and is connected to the heat preservation pipe 303. The exhaust ends of the heat preservation pipe 303 penetrate the lower ends of both sides of the steam chamber 100 and extend to the outside. A partition component is also disposed in the steam chamber 100.

[0023] The steam oven 100 generates a large amount of steam during operation. This steam cooks the food inside the steam oven 100, gradually increasing the pressure. Once a certain pressure is reached, the pressure relief valve 200 automatically opens, releasing excess high-temperature steam to ensure the internal pressure of the steam oven 100 remains within a safe range. The released high-temperature steam enters the steam collection hood 301 and is guided through the transmission pipe 302 on the steam collection hood 301 to the insulation pipe 303 inside the insulation cavity 300. The insulation pipe 303 is distributed in a serpentine pattern on the wall of the insulation cavity 300 near the inner cavity of the steam oven 100, increasing... By increasing the heat dissipation area, high-temperature steam flows within the insulation pipe 303, exchanging heat with the air inside the steam oven 100, thus improving the insulation effect of the steam oven 100 and making the insulation cavity 300 a steam insulation barrier, thereby enhancing the insulation effect of the rice steamer and achieving the purpose of energy saving. By collecting and reusing the high-temperature steam released by the pressure relief valve 200, the insulation effect of the steam oven 100 is significantly improved, reducing energy waste. The exhaust end of the insulation pipe 303 passes through the lower ends of both sides of the steam oven 100 and extends to the outside, which can discharge the remaining low-temperature steam and condensate.

[0024] like Figure 2-4 As shown, the insulation pipes 303 are distributed in a serpentine pattern on the wall surface of the insulation cavity 300 near the inner cavity of the steam box 100, increasing the heat release area during steam recovery.

[0025] like Figure 3-4 As shown, the partition assembly includes a partition plate 401 that is movably inserted into the steam oven 100. A connecting pipe head 402 is threadedly connected to the middle opening of the partition plate 401. A connecting pipe head 403 is threadedly connected to the lower end of the pressure relief valve 200. A high-temperature resistant pipe 404 is provided between the connecting pipe head 403 and the connecting pipe head 402.

[0026] When only a small amount of food needs to be steamed, the partition plate 401 is movably inserted into a set of mounting slots 400 at the corresponding height. Then, the connecting pipe head 402 is threaded to the partition plate 401, and the connecting pipe head 403 is threaded to the pressure relief valve 200. This reduces the area for steaming rice, allowing that portion of the food to be steamed quickly without filling the entire rice steamer with steam, thus achieving high efficiency and energy saving.

[0027] like Figure 3-5 As shown, the partition assembly also includes multiple mounting slots 400 respectively disposed on the left and right sides of the inner cavity of the steam oven 100. The two ends of the partition plate 401 are respectively movably inserted into the adjacent mounting slots 400 on the same side to provide support for the partition plate 401 and its auxiliary mechanisms.

[0028] like Figure 3-5 As shown, the partition assembly also includes an insulation board 405 disposed within the partition plate 401. The insulation board 405 disposed within the partition plate 401 further improves the heat preservation effect of the steam oven 100.

[0029] like Figure 2-4 As shown, the wall surface of the heat preservation cavity 300 near the inner cavity of the steam oven 100 is provided with a groove that matches the heat preservation pipe 303, thereby improving the efficiency and effect of heat exchange.

[0030] like Figure 3-5 As shown, the high-temperature resistant pipe 404 is a high-temperature resistant corrugated expansion pipe. It can maintain good flexibility and sealing performance in high-temperature environments, ensuring the reliability of steam transmission.

[0031] The working principle of the energy-saving rice steamer provided by this utility model is as follows: The steamer 100 generates a large amount of steam, which cooks the food inside. The pressure inside the steamer 100 gradually increases. Once a certain value is reached, the pressure relief valve 200 automatically opens, releasing excess high-temperature steam and ensuring that the internal pressure of the steamer 100 remains within a safe range. The released high-temperature steam enters the gas collection hood 301 and is guided by the transmission pipe 302 on the gas collection hood 301 to the insulation pipe 303 inside the insulation cavity 300. The insulation pipe 303 is distributed in a serpentine pattern on the wall of the insulation cavity 300 near the inner cavity of the steamer 100, increasing the heat dissipation area. The high-temperature steam flows within the insulation pipe 303, exchanging heat with the air inside the steamer 100, improving the insulation effect of the steamer 100, and making the insulation cavity 300 a steam insulation barrier, thereby enhancing the insulation effect of the rice steamer and achieving the purpose of energy saving. The high-temperature steam released by the pressure relief valve 200 is collected and reused, which significantly improves the heat preservation effect of the steam oven 100 and reduces energy waste. The exhaust end of the insulation pipe 303 runs through the lower ends of both sides of the steam oven 100 and extends to the outside, which can discharge the remaining low-temperature steam and condensate. When only a small amount of food needs to be steamed, the partition plate 401 is movably inserted into a set of mounting slots 400 of the corresponding height. Then, the connecting pipe head 402 is threaded to the partition plate 401, and the connecting pipe head 403 is threaded to the pressure relief valve 200, thereby reducing the area for steaming rice. This allows the food in that part to be steamed quickly without filling the entire steam oven with steam, achieving the purpose of high efficiency and energy saving. In addition, the partition plate 401 is equipped with an insulation plate 405, which further improves the heat preservation effect of the steam oven 100. The high-temperature resistant pipe 404 is a high-temperature resistant corrugated expansion pipe, which can maintain good flexibility and sealing in high-temperature environments and ensure the reliability of steam transmission.

[0032] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
