[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0023] The present application will be described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0024] As Figures 1 - 5 shown, a prefabricated food vending cabinet with a heating function includes: a box body 1, a water injection cavity 2 and a heating cavity a 3 are arranged inside the box body 1, the water injection cavity 2 is directly above the heating cavity a 3, and multiple placing plates 101 are installed inside the box body 1; a heating assembly arranged between the box body 1 and the heating cavity a 3 for heating food, the heating assembly includes: a steam cavity 4, a heater a 7, a heating pipe 701 and a heat conducting plate 302; and a water injection assembly arranged between the box body 1 and the water injection cavity 2 for heating water for food, the water injection assembly includes: a water inlet pipe 201, a water nozzle 203 and a heater b 204.

[0025] Among them, through the setting of the heating assembly, the prefabricated food can be heated by steam heat conduction, so that the purchaser can eat the food immediately without looking for heating equipment to heat the prefabricated food; secondly, through the setting of the water injection assembly, hot water can be provided for some prefabricated foods, which can not only enrich the taste of the food, but also preheat the food, accelerate the heating of the food, and at the same time provide hot water for the purchaser to drink.

[0026] Among them, a partition plate 202 is fixed inside the water injection cavity 2. A heater b204 is installed on one side of the water injection cavity 2. A heating conduit 205 is connected to one side of the heater b204. A water inlet pipe 201 is connected to the top of the box body 1, and the water inlet pipe 201 communicates with the water injection cavity 2. A water nozzle 203 is installed at the bottom of the partition plate 202. Water flows into the water injection cavity 2 from the water inlet pipe 201 and is heated by the heating conduit 205. The water injection cavity 2 can provide hot water to preheat some prefabricated foods, and at the same time can maintain the food temperature and taste of some prefabricated foods, increasing the dining comfort.

[0027] Among them, a base plate 301 is installed inside the heating cavity a3, and a steam cavity 4 is provided at the bottom of the base plate 301. A heat conduction plate 302 is fixedly connected to the upper surface of the base plate 301. A plurality of heat conduction fins 303 are connected to the bottom of the base plate 301, and the bottom ends of the plurality of heat conduction fins 303 all extend into the steam cavity 4. The steam conducts heat through the heat conduction fins 303 to the heat conduction plate 302 to heat the food. The heat conduction fins 303 can increase the contact area with the steam, improve the heat conduction efficiency, can conduct heat effectively and quickly, can quickly heat the food, and the arrangement of the plurality of heat conduction fins 303 can evenly heat the heat conduction plate 302, thus avoiding the situation of uneven heat transfer, local overheating of the heat conduction plate 302 and too long heating time for prefabricated foods when a single heat conduction fin 303 conducts heat. Moreover, the heat conduction of a single heat conduction fin 303 will concentrate the heat in one position, forming a temperature difference with the surrounding, resulting in uneven heating of the heat conduction fin 303 and too long heating time for prefabricated foods, and excessive energy consumption.

[0028] Among them, a steam box 401 is arranged inside the steam cavity 4. A plurality of air vents 402 are arranged on the upper surface of the steam box 401. A steam conduit 601 is installed on the lower surface of the steam box 401. A diversion pipe 403 is connected to the bottom of the steam cavity 4. Steam enters the steam box 401 from the steam conduit 601 and enters the steam cavity 4 through the air vents 402, contacting the wall surface and the heat conduction fins 303. Since the wall surface temperature is lower than the steam dew point temperature, the steam loses heat. As the heat dissipates, the steam temperature decreases. When the steam temperature drops below its saturation temperature, the steam begins to condense into water droplets. The water droplets flow back to the water storage tank 5 through the diversion pipe 403, which can effectively avoid the situation of liquid leakage and also save water and reduce losses.

[0029] Among them, a water storage tank 5 is arranged below the heating chamber a3. One side of the water storage tank 5 is connected to a heating tank 6. One end of the water storage tank 5 is connected to a water injection pipe 501. A return pipe is connected between the heating tank 6 and the water storage tank 5, and a check valve 502 is installed inside the return pipe. One end of the steam conduit 601 communicates with the heating tank 6. Water flows into the water storage tank 5 from the water injection pipe 501, and then enters the heating tank 6 through the return pipe. The check valve 502 is installed in the return pipe. The check valve 502 can prevent the liquid from flowing backward or backflowing. When the heating pipe 701 in the heating tank 6 heats the water and the water forms steam, the water in the heating tank 6 decreases, and the pressure relative to the water storage tank 5 becomes smaller. A pressure difference is formed between the two. Due to the pressure difference, the check valve 502 releases the valve, and the water flows from the water storage tank 5 into the heating tank 6, so that the water can be automatically replenished, avoiding the situation that the liquid in the heating tank 6 burns dry and causing the heater a7 to be overloaded. In the lightest case, the electrical appliance is burned out, and in the worst case, a fire occurs. Therefore, through the setting of the check valve 502, not only can the water inside the heating tank 6 be prevented from flowing back into the water storage tank 5, but also the heating tank 6 can be protected. Before operating the machine, water needs to be poured into the water storage tank 5 from the water injection pipe 501 connected to one end of the water storage tank 5.

[0030] Among them, a heater a7 is arranged on one side of the heating tank 6. One side of the heater a7 is connected to a heating pipe 701. The heating pipe 701 is energized through the heater a7 to generate Joule heat, and then the water inside the heating tank 6 is heated up by the Joule heat, and the water generates steam after being heated to a certain temperature.

[0031] Working principle:

[0032] Before the machine works, water needs to be poured into the water storage tank 5 from the water injection pipe 501. Water flows into the water storage tank 5 from the water injection pipe 501, and then enters the heating tank 6 through the return pipe. A check valve is installed in the return pipe, and the check valve 502 can prevent the liquid from flowing backward or backflowing.

[0033] When the machine is working, when the heating tube 701 in the heating box 6 heats the water, after the water forms steam, the water in the heating box 6 decreases. Due to the pressure difference, the one-way valve loosens the valve, and the water flows from the water storage tank 5 into the heating box 6. The heating box 6 can quickly heat the liquid by energizing the heating tube 701 through the heater a7 to generate steam. The steam enters the steam box 401 through the steam conduit 601 and exits through the air hole 402 into the steam chamber 4. The steam conducts heat through the heat conducting fin 303 to the heat conducting plate 302, thereby heating the food. Then, when the steam enters the steam chamber 4, it contacts the wall surface and the heat conducting fin 303. Since the wall surface temperature is lower than the steam dew point temperature, the steam loses heat. As the heat dissipates, the steam temperature decreases. When the steam temperature drops below its saturation temperature, the steam begins to condense into water droplets. The water droplets flow back to the water storage tank 5 along the diversion pipe 403, which can effectively avoid the situation of liquid leakage and also save water and reduce losses.

[0034] Water flows into the water injection chamber 2 from the water inlet pipe 201 and is heated by the heating conduit 205. When some prefabricated foods need to be added with hot water, the prefabricated foods can be placed under the water nozzle 203, and hot water can be injected into the prefabricated foods through the water nozzle. At the same time, hot water is provided for the purchasers to drink.
