Description

Technical Field

[0001] The utility model relates to the field of stove heat recovery, in particular to a waste heat utilization device for commercial frying stoves. Background Art

[0002] Commercial frying stoves are the main cooking stoves in restaurants, canteens and other catering industries. They have been in use for a long time and have a high market share. Generally, commercial frying stoves sold on the market do not have a waste heat utilization device, and hot smoke is directly discharged, resulting in energy waste. For example, the patent disclosed in publication number CN102778077A uses waste heat utilization devices installed on the stove to reduce energy consumption.

[0003] Currently, most of the waste heat utilization products are integrated stoves. Due to their high production costs, expensive sales prices, low market acceptance, few customers, and the inability to directly utilize existing stoves. Utility Model Content

[0004] The purpose of the utility model is to provide a waste heat utilization device for commercial frying stoves to solve the above technical problems.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a waste heat utilization device for a commercial frying stove, comprising an annular shell, a pot-supporting chamfer, a flame channel, a hot smoke inlet hole, a stove mouth closed edge, a water inlet pipe, a water outlet pipe, a heating pipe, an exhaust port, and a base. The upper inner end of the annular shell is provided with a pot-supporting chamfer, the flame channel is arranged at the middle ring mouth of the annular shell, the hot smoke inlet hole is distributed in the middle of the inner end of the annular shell, the stove mouth closed edge is fixed to the bottom of the inner end of the annular shell, the water inlet pipe is plugged into the front right part of the side end of the annular shell, the water outlet pipe is plugged into the front left part of the side end of the annular shell, the two ends of the heating pipe are surrounded by the inside of the annular shell by connecting the water inlet pipe and the water outlet pipe respectively, the exhaust port is opened at the outer end of the annular shell, and the base is installed at the bottom end of the annular shell.

[0006] Based on the above technical solution, the base includes a bottom plate, a mounting interface, thermal fins, and a tube bracket groove. A mounting interface is opened in the middle of the bottom plate, and the bottom plate is connected to the bottom end of the annular shell through the mounting interface. The thermal fins are distributed at the top of the bottom plate, and the tube bracket groove is opened in the middle of the top of the thermal fins, and the heating tube is connected to the thermal fins through the tube bracket groove.

[0007] Based on the above technical solution, the heat-conducting fins absorb the heat entering through the hot smoke inlet holes and transfer it to the heating tube.

[0008] Compared with the prior art, the utility model has the following advantages: the utility model directly places and installs the annular shell and the base on the stove mouth, and cooperates with the wok to change the discharge channel of the hot smoke after the flame burns, and heats the water in the heat pipe with heat-conducting fins in this channel before discharging it. It is easy to use, reduces energy consumption, and does not need to replace the stove. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1 to 3 As shown, a waste heat utilization device for a commercial frying stove comprises an annular shell 1, a pot supporting chamfer 2, a flame channel 3, a hot smoke inlet hole 4, a stove mouth closed edge 5, a water inlet pipe 6, a water outlet pipe 7, a heating pipe 8, an exhaust port 9, and a base 10. The upper part of the inner side end of the annular shell 1 is provided with a pot supporting chamfer 2, the flame channel 3 is arranged at the middle ring mouth of the annular shell 1, the hot smoke inlet hole 4 is distributed in the middle of the inner side end of the annular shell 1, the stove mouth closed edge 5 is fixed to the bottom of the inner side end of the annular shell 1, the water inlet pipe 6 is plugged into the front right part of the side end of the annular shell 1, the water outlet pipe 7 is plugged into the front left part of the side end of the annular shell 1, the two ends of the heating pipe 8 are surrounded by the inside of the annular shell 1 by connecting the water inlet pipe 6 and the water outlet pipe 7 respectively, the exhaust port 9 is opened at the outer side end of the annular shell 1, and the base 10 is installed at the bottom end of the annular shell 1.

[0015] The base 10 includes a bottom plate 11, a mounting interface 12, heat-conducting fins 13, and a tube bracket 14. The bottom plate 11 has a mounting interface 12 in the middle, and the bottom plate 11 is connected to the bottom end of the annular shell 1 through the mounting interface 12. The heat-conducting fins 13 are distributed at the top of the bottom plate 11. The tube bracket 14 is opened in the middle of the top of the heat-conducting fins 13, and the heating tube 8 is connected to the heat-conducting fins 13 through the tube bracket 14.

[0016] The heat conducting fins 13 absorb the heat entering from the hot smoke inlet holes 4 and transfer it to the heating tubes 8 .

[0017] The working principle of the utility model is as follows: the device is installed on the stove mouth through the stove mouth closing edge 5, and the water inlet pipe 6 and the water outlet pipe 7 are connected to the water pipe, and the pot is placed on the annular shell 1 through the pot support chamfer 2, so that only the hot smoke inlet hole 4 can flow air between the pot and the stove mouth. After starting the stove, the flame is heated in the flame channel 3. At the same time, the hot smoke enters the annular shell 1 through the hot smoke inlet hole 4, and is discharged through the exhaust port 9 after being absorbed by the heat-conducting fins 13 and the heating tube 8. Water is injected into the heating tube 8 through the water inlet pipe 6. The water is heated by the heat transferred by the heating tube 8 and the heat-conducting fins, and then flows out as hot water through the water outlet pipe 7, so that the waste heat is recycled; it is easy to use, reduces energy consumption, and does not require the replacement of the stove.

[0018] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
