Description

Technical Field

[0001] The utility model relates to the field of steamers, in particular to a multifunctional steamer with scale prevention function. Background Art

[0002] At present, the structure of a steamer is as shown in a steamer in a Chinese patent document with the application number: CN202321651916.4. It mainly includes a pot body, a steaming grid and a pot lid. The steaming grid is placed on the pot body to form a steam generation cavity between the steaming grid and the pot body. The pot lid is covered on the steaming grid to form a cooking cavity between the pot lid and the steaming grid. The feature is that the steaming grid is vertically through, and a steaming tray with steam through holes is detachably arranged at the bottom of the steaming grid. Supporting feet are arranged below the steaming tray. In order to better observe the state of food during the steaming process, the pot lid generally uses transparent materials. When the pot lid is formed by plastic, due to its low own weight, the steam pressure is easy to lift the pot lid, causing steam to leak from the connection seam between the pot lid and the pot body or the steaming grid, reducing the steaming efficiency. When the pot lid is formed by glass, the pot lid can be pressed against the pot body or the steaming grid by its own weight to achieve sealing. However, when taking and placing food, the entire pot lid needs to be moved away. Its weight increases the burden on the user when taking and placing, and a position for placing the pot lid also needs to be vacated near the steamer. In addition, after the user lifts the pot lid, the condensed water on the inner wall of the pot lid will drip everywhere near the steamer, increasing the cleaning work. Therefore, the applicant provides a new steamer solution through the improvement and perfection of the existing technology for consumers to choose and use. Summary of the Invention

[0023] The present invention will be further described below with reference to the drawings and embodiments.

[0024] As Figures 1 to 6 shown, a multifunctional steamer capable of preventing scale includes a base 1 and an outer cover 2 covering the top surface of the base 1. A cooking cavity 201 is defined by enclosing between the outer cover 2 and the base 1. A steam generating assembly 3 communicating with the cooking cavity 201 is provided inside the base 1. A steam nozzle 4 placed in the cooking cavity 201 is detachably connected to the base 1. The steam nozzle 4 is connected to the air outlet port of the steam generating assembly 3, and an air jet port 401 communicating the air outlet port and the cooking cavity 201 is provided on the steam nozzle 4.

[0025] The steam nozzle on this multifunctional steamer can achieve a detachable design, with a simple structure, detachable and installable, which helps to maintain and clean the inside of the steam nozzle in the later stage, prevent the problem of scale accumulation on the inner wall of the steam nozzle, keep the steam nozzle clean, avoid the scale peeling off and spraying into the cooking cavity with the high-temperature steam and contacting the food, ensuring hygienic safety.

[0026] The steam nozzle 4 includes a jet straight pipe 41 with a closed top end and an open bottom end. The jet straight pipe 41 extends directly upward from the top surface of the base 1. Two jet ports 401 are arranged along the height direction on the side wall of the jet straight pipe 41; preferably, two jet ports 401 are provided so that steam can be sprayed into the upper space and the lower space of the cooking chamber 201 respectively, enabling the steam to quickly fill the entire cooking chamber 201.

[0027] The steam nozzle 4 is arranged against the inner wall surface of the outer cover 2, and the jet ports 401 are opened on the side of the jet straight pipe 41 facing away from the inner wall surface of the outer cover 2. One or more jet ports 401 face the central position of the cooking chamber 201 at the same angle; the steam nozzle 4 is arranged at the edge of the cooking chamber 201. This structure does not occupy the space for placing food in the cooking chamber 201 and avoids food blocking the jet ports 401.

[0028] The jet port 401 has a rectangular curved surface structure, and the arc length of the jet port 401 is greater than the height of the jet port 401. This ratio can form a flat jet port, enabling the sprayed steam to be distributed outward in a fan shape, improving the speed at which the steam fills the entire cooking chamber 201. Preferably, the opening angle of the jet port 401 is approximately 180° in this embodiment, and the jet port 401 with this opening angle can just cover the entire cooking chamber 201.

[0029] A joint through hole 101 is opened on the top surface of the base 1. An air inlet joint 5 is arranged in the joint through hole 101. The air inlet joint 5 is connected to the air outlet port of the steam generating assembly 3. The lower part of the jet straight pipe 41 is detachably inserted into the air inlet joint 5 and communicated with the air outlet port; through the tight fit between the air inlet joint 5 and the jet straight pipe 41, the jet straight pipe 41 can be quickly assembled and disassembled, and sealing is completed immediately after assembly and disassembly.

[0030] An introduction inclined surface 411 is opened at the bottom of the jet straight pipe 41; the introduction inclined surface 411 can improve the efficiency of inserting the jet straight pipe 41 into the joint through hole 101.

[0031] The air inlet joint 5 is integrally made of an elastic material; a hollow cavity 51 that forms a clearance fit with the jet straight pipe 41 and a sealing port 52 that forms an interference fit with the jet straight pipe 41 are opened in the air inlet joint 5. The lower part of the jet straight pipe 41 passes through the sealing port 52 and is inserted into the hollow cavity 51; the sealing port 52 sleeves the jet straight pipe 41 with interference, which can prevent steam from leaking through the gap between the two, while the hollow cavity 51 makes the lower part of the jet straight pipe 41 in a loose state, reducing the contact area between the jet straight pipe 41 and the air inlet joint 5, making it easier to disassemble the steam nozzle.

[0032] The base 1 at least includes a housing 11 and a heat insulation disc 12. A supporting ring 121 is provided on the upper part of the housing 11, and the edge of the heat insulation disc 12 abuts against the supporting ring 121. An outer ring 53 extends from the side wall of the air inlet joint 5. After the heat insulation disc 12 is fixedly connected to the housing 11, the outer ring 53 is clamped between the heat insulation disc 12 and the supporting ring 121 to fix the air inlet joint 5 on the base 1.

[0033] The base 1 further includes a chassis 13. A sealing ring 14 is positioned and sleeved on the edge of the heat insulation disc 12, the edge of the chassis 13 abuts against the sealing ring 14. After the chassis 13 is fixedly connected to the heat insulation disc 12 through a connecting member, the sealing ring 14 is clamped between the chassis 13 and the heat insulation disc 12, and the bottom of the outer cover 2 presses against the sealing ring 14 to seal the steaming cavity 201.

[0034] The connecting members between the housing 11 and the heat insulation disc 12, and the connecting members between the chassis 13 and the heat insulation disc 12 mainly include several threaded posts and through holes corresponding to the threaded posts. Through fastening units such as screws passing through the through holes and the threaded posts from bottom to top, the housing 11 is fixedly connected to the heat insulation disc 12, and the chassis 13 and the heat insulation disc 12 are fixedly connected. Both are fixed by pulling tightly up and down. The above connection method belongs to a conventional connection structure and will not be elaborated in detail here.

[0035] It further includes a main controller 7. The chassis 13 is made of a metal material, and a heating tube 16 electrically connected to the main controller 7 is connected to the bottom surface. The heating tube 16 and the chassis 13 form a heating plate. The heating plate can increase the temperature in the steaming cavity 201, enable the steam to be reheated, improve the steam temperature and the steaming efficiency at the same time. Moreover, when the condensed water drops onto the heating plate, the heating plate heats the condensed water to vaporize it again to form steam, realizing the recycling of the condensed water and preventing water accumulation on the base.

[0036] The steam generating assembly 3 includes a steam generator 8 and a water storage tank 9. The water storage tank 9 is detachably connected to the base 1. The water outlet of the water storage tank 9 is communicated with the water inlet of the steam generator 8 through a water pump 10. The water outlet of the steam generator 8 is connected to the air inlet joint 5. The steam generator 8 and the water pump 10 are electrically connected to the main controller 7.

[0037] The steam generator 8 can directly heat the water in the water storage tank 9 to form steam, and then spray it into the steaming cavity through the steam nozzle 4. The water storage tank 9 is detachably connected, which is convenient for adding water at any time and increasing the usage time of the steamer.
