Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooking utensils, and in particular to an improvement of a rice steamer. Background Technology
[0002] Rice steamers are common cooking appliances used in canteens and restaurants for steaming food. They typically have a heating plate at the bottom to heat purified water, creating steam that circulates inside the steamer. The steam's heat is used to cook the food. Most rice steamers have a steam vent to prevent excessive steam pressure inside the cabinet. This steam is often directly discharged, forming condensation on the kitchen walls. This not only wastes steam but also creates slippery conditions in kitchens, which are often oily and greasy, increasing the risk of falls and injuries for those working in the kitchen. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a steam-circulating rice steamer.
[0004] This utility model is achieved using the following technical solution: a steam-circulating rice steamer, comprising a cabinet body with an opening on one side, a hinged cabinet door on the cabinet body for closing or opening the opening, an exhaust component and a condensation component on the cabinet body, the exhaust component being connected to the interior of the cabinet body, the condensation component being disposed on the exhaust component, and steam inside the cabinet body flowing from the exhaust component to the condensation component.
[0005] The exhaust assembly includes an exhaust pipe, one end of which is fixed to the cabinet and communicates with the interior of the cabinet, and the other end of which is communicated with the condensation assembly.
[0006] The condensation assembly includes a condensation box and a return water pipe. The condensation box is fixed to the outer wall of the cabinet and is connected to the exhaust pipe. The exhaust pipe delivers steam into the condensation box. One end of the return water pipe is fixed to the bottom of the condensation box and is connected to the condensation box. The other end of the return water pipe passes through the cabinet and is connected to the heating plate inside the cabinet.
[0007] The condenser box includes a box body and fins. The fins are fixed inside the box body and placed on the top of the box body. The lower edge of the fins and the bottom of the box body form a receiving cavity for condensing water. A water outlet is opened at the bottom of the box body and communicates with the return water pipe. A heat dissipation hole is opened at the top of the box body.
[0008] The condenser box also includes a fan, which is located in the heat dissipation hole and fixed on the inner wall of the heat dissipation hole. The fan is used to blow cold air into the fins.
[0009] The condensation assembly includes a condenser tube, one end of which passes through the cabinet and is connected to the heating plate of the rice steamer.
[0010] The other end of the condenser tube extends upward along the height of the cabinet and is sealed by a sealing plate. An insertion hole is provided on the sealing plate. The exhaust pipe extends downward and is inserted into the condenser tube through the insertion hole. A gap is provided between the end of the exhaust pipe inserted into the condenser tube and one end of the condenser tube to allow steam to pass through.
[0011] A water outlet is provided at the bottom of the condenser tube, and the water outlet is connected to the heating plate of the rice steamer through an elbow.
[0012] The cabinet is equipped with a water inlet.
[0013] Compared to existing technologies, this invention condenses the steam discharged from the exhaust pipe into condensate in a condenser box, which then flows back into the heating plate of the rice steamer. This allows for reuse, as most of the discharged steam is re-condensed into distilled water, thus reducing the amount of steam discharged from the rice steamer. Consequently, less condensation forms on the kitchen walls and floors, keeping the kitchen as dry as possible and reducing the risk of slips and falls. Simultaneously, converting the discharged steam into condensate for reuse conserves water resources. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0023] Reference Figure 1-7 A steam-circulating rice steamer includes a cabinet body 1 with an opening on one side, and a hinged door 2 on the cabinet body 1 for closing or opening the opening. A water inlet 5 is provided on the cabinet body 1 for replenishing water to the heating plate of the rice steamer. The cabinet body 1 is equipped with an exhaust assembly and a condenser assembly 4. The exhaust assembly is connected to the interior of the cabinet body 1, and the condenser assembly is located on the exhaust assembly. Steam inside the cabinet body 1 flows from the exhaust assembly to the condenser assembly 4. When the steam passes through the condenser assembly 4, it is condensed into distilled water and flows back into the rice steamer to be reheated into steam. This allows most of the steam water to be condensed and reused as distilled water, thus saving water resources. Furthermore, the reduced amount of overflowing steam lowers the humidity in the kitchen and effectively prevents slippery floors, reducing the occurrence of slippery accidents.
[0024] In this embodiment, the exhaust assembly includes an exhaust pipe 3. One end of the exhaust pipe 3 is fixed to the cabinet 1 and communicates with the interior of the cabinet 1, while the other end of the exhaust pipe 3 is connected to the condensation assembly 4. Excess steam enters the condensation assembly 4 through the exhaust pipe 3. Most of the steam water is condensed and reused as distilled water, thereby saving water resources. Furthermore, due to the reduced amount of overflowing steam, the humidity in the kitchen is lowered, effectively preventing the floor from becoming slippery and reducing the occurrence of slip accidents.
[0025] Reference Figure 1-5 In this embodiment, one implementation of the condenser assembly 4 is as follows: the condenser assembly 4 includes a condenser box 41 and a return water pipe 42. The condenser box 41 is fixed to the outer wall of the cabinet 1 and connected to the exhaust pipe 3. The exhaust pipe 3 supplies steam into the condenser box 41. One end of the return water pipe 42 is fixed to the bottom of the condenser box 41 and connected to the condenser box 41. The other end of the return water pipe 42 passes through the cabinet 1 and connects to the heating plate inside the cabinet 1. (Refer to...) Figure 5The condenser box 41 includes a box body 411 and fins 412. The fins 412 are fixed inside the box body 411 and located on top of the box body 411. A receiving cavity 413 for collecting condensate is formed between the lower edge of the fins 412 and the bottom of the box body 411. A water outlet 46 is opened at the bottom of the box body 411 and communicates with a return water pipe 42. A heat dissipation hole 414 is opened at the top of the box body 411. Steam enters the box body 411 and comes into contact with the fins 412. It condenses on the surface of the fins 412 and drips into the receiving cavity 413. The condensate in the receiving cavity 413 is returned to the heating plate by the return water pipe 42 and reheated into steam. This achieves the reuse of distilled water after most of the steam water is condensed, thereby saving water resources. In addition, the reduced amount of overflowing steam lowers the humidity in the kitchen and effectively prevents the floor from becoming slippery, reducing the occurrence of slip accidents. Steam that cannot condense in time can escape through the heat dissipation hole 414 to avoid excessive pressure in the cabinet 1 and increase safety. Figure 1 and Figure 3 The length of the condenser box 41 can be selected according to actual needs. Depending on the length of the condenser box 41, the return pipe 42 can also consist of a section of elbow and a section of straight pipe, depending on the fixed position of the condenser assembly 4, allowing for flexible use. When the condenser box 41 is relatively long and its bottom is close to the return point, such as... Figure 3 and Figure 4 As shown, only one elbow section can be used as the return channel. When the bottom of the condenser box 41 is far from the return position, a combination of straight pipe and elbow can be used to adapt to different usage requirements.
[0026] Reference Figures 1-4 as well as Figure 5 Based on the above embodiments, the condenser box 41 further includes a fan 415, which is disposed in the heat dissipation hole 414 and fixed on the inner wall of the heat dissipation hole 414. The fan 415 is used to blow cold air into the fins 412. The cold air blown in by the fan 415 is used to cool the fins 412, thereby keeping the temperature of the fins 412 low, enabling continuous cooling of steam and improving condensation efficiency.
[0027] Reference Figure 6 , Figure 7In this embodiment, another implementation of the condenser assembly 4 is as follows: The condenser assembly 4 includes a condenser pipe 43, one end of which passes through the cabinet body and connects to the heating plate of the rice steamer; the other end of the condenser pipe 43 extends upward along the height direction of the cabinet body 1 and is closed by a sealing plate 44. An insertion hole is provided on the sealing plate 44, and an exhaust pipe 3 extends downward and is inserted into the condenser pipe 43 through the insertion hole. A gap 45 is provided between the end of the exhaust pipe 3 inserted into the condenser pipe 43 and one end of the condenser pipe 43 to allow steam to pass through. A water outlet 46 is provided at the bottom of the condenser pipe 43, and the water outlet 46 is connected to the heating plate of the rice steamer through an elbow. In this solution, the condenser pipe 43 is lengthened, allowing more water vapor to be condensed simultaneously. This enables most of the steam water to be condensed and reused as distilled water, thereby saving water resources. Furthermore, the reduced amount of overflowing steam lowers the humidity in the kitchen and effectively prevents the floor from becoming slippery, reducing the occurrence of slip accidents. Steam that cannot be condensed can escape through the gap between the cabinet body 1 and the cabinet door 2, increasing safety.
[0028] Compared to existing technologies, in this invention, the steam discharged from the exhaust pipe 3 is condensed into condensate in the condenser box 41 and then flows back into the heating plate of the rice steamer. This allows for reuse, as most of the discharged steam is re-condensed into distilled water for reuse, thus reducing the amount of steam discharged from the rice steamer. Consequently, less condensate forms on the kitchen walls or floor, keeping the kitchen as dry as possible and reducing the risk of slips and falls. Simultaneously, converting the discharged steam into condensate for reuse conserves water resources.
[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
