Description

Technical Field

[0001] This utility model belongs to the field of steam oven technology, specifically relating to a water-cooled heat dissipation structure for a steam oven and the steam oven thereof. Background Technology

[0002] Traditional steam ovens release high-temperature steam directly through the vents during cooking, reaching temperatures exceeding 100°C. If users touch or approach the vent area, they are highly susceptible to burns. For example, users may accidentally touch the steam with their arms while operating the oven. This poses a safety hazard, especially for children and the elderly, who are near the appliance while in the kitchen, potentially resulting in severe burns. Furthermore, the high-temperature steam can scorch cabinets and walls, and even damage nearby electrical wiring. Therefore, reducing the steam temperature is a crucial requirement for ensuring user safety.

[0003] Existing steam ovens typically use condensation cooling by incorporating condensation channels, condensation plates, and condensation boxes. When high-temperature steam flows through these low-temperature condensation channels and other equipment, it quickly transfers heat to the channel walls or plates, condensing the moisture in the steam into water droplets, reducing steam emissions, and lowering the temperature of the remaining steam and condensate.

[0004] However, relying solely on cooling structures such as condenser plates and condenser boxes, the outlet temperature can still reach 80 degrees Celsius, which can easily cause burns to the hands and does not meet the safe emission gas temperature standards. Summary of the Invention

[0005] To address the problems in related technologies, this utility model proposes a water-cooled heat dissipation structure for a steam oven and the steam oven itself. A water-cooled heat dissipation structure is added to the exhaust pipe and combined with the water circuit of the evaporator of the steam oven to further reduce the temperature of the steam oven's exhaust port and prevent burns to the hands.

[0006] This utility model is implemented as follows:

[0007] A water-cooled heat dissipation structure for a steam oven is provided, which is located in one section of the exhaust pipe and connected to the exhaust pipe. The exhaust pipe includes an inlet and an outlet. The inlet is connected to the exhaust port of the steam oven. A condensation box is connected to the outlet, and the condensation box is provided with several air outlets.

[0008] The water-cooled heat dissipation structure includes a connecting shell connected to an exhaust pipe, a heat sink inside the connecting shell, a heat dissipation pipe above the heat sink, a water pump connected to one end of the heat dissipation pipe, and an evaporator connected to the other end of the heat dissipation pipe.

[0009] The high-temperature gas inside the steam oven is discharged through the exhaust port and flows into the exhaust pipe through the inlet. The water pump delivers water to the heat dissipation pipe. The high-temperature gas in the exhaust pipe flows through the heat dissipation fins and exchanges heat with the heat dissipation pipe. After cooling the gas, it enters the condenser box through the outlet. After being cooled again in the condenser box, it is discharged through the exhaust port. The water in the heat dissipation pipe flows into the evaporator after heat exchange and provides steam for the steam oven.

[0010] Preferably, a metal cover is provided above the heat dissipation pipe, and the side of the metal cover facing the heat dissipation pipe has an upper pipe groove adapted to the heat dissipation pipe.

[0011] Specifically, the metal cover is an aluminum cover, and the metal cover and the heat dissipation pipe together form part of the heat dissipation structure, so that the gas heat is dissipated by water cooling in the exhaust pipe.

[0012] Preferably, a fan is provided at the upper end of the metal cover, and the fan blows air toward one side of the metal cover.

[0013] Specifically, a fan can concentrate the heat from the gas into the heat pipe, improving the efficiency and effectiveness of heat dissipation.

[0014] Preferably, the heat dissipation pipe is a continuous U-shaped structure, fixed between the metal cover and the heat sink, and the side of the heat sink facing the heat dissipation pipe has a fixing plate, and the fixing plate is provided with a lower pipe groove adapted to the heat dissipation pipe.

[0015] Specifically, the U-shaped arrangement can improve the uniformity of heat dissipation; by using the upper and lower tube slots to fix the heat dissipation tubes between the metal cover and the fixing plate of the heat sink, the high-temperature gas can make full contact and dissipate heat when it flows through the heat sink.

[0016] Preferably, the side of the fixing plate facing away from the heat dissipation pipe is provided with a plurality of heat dissipation sub-plates, which together with the fixing plate form the heat dissipation fins. The heat dissipation sub-plates are arranged in parallel in the exhaust pipe, and the high-temperature gas in the exhaust pipe flows through the gaps between the heat dissipation sub-plates.

[0017] Specifically, the heat sink is made of aluminum alloy; the plane of the heat sink is parallel to the flow direction of the high-temperature gas in the exhaust pipe; the high-temperature gas flows between the heat sinks and works with the heat pipes to dissipate heat.

[0018] Preferably, the connecting shell is installed in the exhaust pipe, and connecting pipes are provided at both ends of the connecting shell, which are connected to the exhaust pipe. The connecting shell is located between the exhaust port and the air outlet. The upper end of the connecting shell is provided with a grid adapted to the heat sink, and the heat sink passes through the grid and is fixed inside the connecting shell.

[0019] Specifically, the connecting shell is mainly used to fix the water-cooled heat dissipation structure and position it in the path of high-temperature gas flow. The connecting shell is a rectangular box shape with connecting pipes at both ends, which are connected to the exhaust pipes at both ends respectively, and heat dissipation fins and other structures are set in the middle. The grid can fix the heat dissipation fins and also make full contact between the heat dissipation structures to improve the heat dissipation effect.

[0020] Preferably, the exhaust pipe is T-shaped and located at the top of the steam oven. The downward-extending part of the exhaust pipe is the inlet, and the exhaust port is located at the top of the steam oven. The inlet is connected to the exhaust port at the top of the steam oven. A fan is provided at the end of the exhaust pipe away from the outlet, and the inlet is located between the fan and the outlet. High-temperature steam flows upward into the exhaust pipe from the exhaust port, and the fan at the end away from the outlet blows the high-temperature steam from the inlet to one side of the outlet.

[0021] Specifically, the fan and the outlet are located at opposite ends of the T-shape, with the downward-extending middle section serving as the inlet, which connects directly to the exhaust vent at the top of the steam oven. The fan can also be a regular fan, primarily used to direct the high-temperature steam exhausted upwards from the steam oven from one end of the T-shaped exhaust pipe to the outlet at the other end.

[0022] Preferably, the condenser box is provided with a drain outlet, and the bottom of the steam oven is provided with a wastewater box. The drain outlet is connected to the wastewater box through a pipe, and the condensed water flows from the drain outlet to the wastewater box.

[0023] Specifically, the width of the condenser box is the same as that of the steam oven. It is located at the front of the steam oven, above the oven door. The gas from the exhaust pipe is cooled by the water-cooled heat dissipation structure and then further cooled by the condenser box before being discharged from the front outlet. The water produced by the condensation of the gas entering the condenser box flows out through the drain outlet and into the wastewater box at the bottom through the pipe.

[0024] A drain outlet is installed in the condensate box to drain water and prevent water accumulation, which can lead to bacteria, grease, and mold growth.

[0025] Preferably, the water pump is located at the lower end of the steam oven, and the lower end of the steam oven is also provided with a water tank. The water pump is also connected to the water tank, and the water pump delivers the water in the water tank to the heat dissipation pipe.

[0028] Specifically, the steam oven includes an outer shell and a cavity set inside the outer shell. The water-cooled heat dissipation structure, exhaust pipe, condenser box, water pump, evaporator, wastewater box, water tank, etc. are all located on the outside of the cavity and the inside of the outer shell.

[0029] Compared with the prior art, the present invention achieves the following beneficial effects:

[0030] This utility model provides a water-cooled heat dissipation structure for a steam oven and the steam oven itself. A water-cooled heat dissipation structure is installed in one section of the exhaust pipe. The structure consists of heat sinks and heat dissipation pipes. One end of the heat dissipation pipe is connected to a water pump, and the other end is connected to an evaporator. The inlet of the exhaust pipe is connected to the exhaust port of the steam oven, and the outlet is connected to a condenser box. High-temperature gas inside the steam oven flows into the exhaust pipe, is cooled by the water-cooled heat dissipation structure, enters the condenser box for further cooling, and is then discharged from the outlet of the condenser box, thus improving the cooling effect of high-temperature steam. The water in the heat dissipation pipes can be directly sourced from the steam oven. After being cooled and heat-exchanged by the heat dissipation pipes, the water flows to the evaporator for preheating. The evaporator then further supplies steam to the steam oven, forming a circulation. This not only improves the cooling effect of steam discharge but also increases the steam efficiency of the evaporator. Attached Figure Description

[0076] This utility model provides a water-cooled heat dissipation structure 3 for a steam oven 1 and the steam oven 1 thereof. The high-temperature steam of the steam oven 1 enters the exhaust pipe 2 through the exhaust port 11. The fan 23 at one end of the exhaust pipe 2 blows the high-temperature gas discharged upward toward one side of the outlet 22. After being cooled by the water-cooled heat dissipation structure 3, the gas flows out of the outlet 22 and then into the condensation box 4. After being cooled again by the condensation box 4, the gas is discharged through the air outlet 41. At this time, the temperature of the air outlet 41 does not exceed 60 degrees Celsius, which meets the discharge temperature standard. The water generated by condensation in the condensation box 4 flows to the wastewater box 7 through the drain port 42.

[0077] When the high-temperature gas in the exhaust pipe 2 passes through the water-cooled heat dissipation structure 3, it undergoes heat exchange through the heat sink 32, heat dissipation pipe 33, and fan 35 in the water-cooled heat dissipation structure 3 to achieve cooling. One end of the heat dissipation pipe 33 is connected to the water pump 5, which pumps water from the water tank 51 into the heat dissipation pipe 33 for water cooling, and outputs it from the other end of the heat dissipation pipe 33 to the evaporator 6. The evaporator 6 operates to preheat the water and provide steam to the steam oven 1, forming a circulation. This not only improves the cooling effect, but also allows the water after heat exchange to be further utilized through the evaporator 6, thereby improving efficiency.
