[0024] Embodiment 1

[0025] This embodiment provides a heat dissipation and condensation device, which includes: a condensing assembly 100 and an air duct cover 200. The air duct cover 200 has an air inlet channel and an air outlet channel. The condensing assembly 100 is arranged at the connection of the air inlet channel and the air outlet channel. External gas flows through the condensing assembly 100 through the air inlet channel, exchanges heat with the steam in the condensing assembly 100, and then is discharged from the air outlet channel to form a directional air flow, and the air pressure at the air inlet channel is less than the air pressure at the air outlet channel.

[0026] Please refer to Figure 1 and Figure 2 As shown, in this embodiment, the air duct cover 200 is a hollow shell structure inside. An installation space, an air inlet channel and an air outlet channel are formed inside the air duct cover 200. The air inlet channel communicates with the air outlet channel through the condensation assembly 100. At the same time, the air duct cover 200 is provided with an air inlet of the air inlet channel and an air outlet of the air outlet channel for communicating with the external environment for heat exchange. The condensation assembly 100 is used to connect to external steam. The high-temperature steam flows in the condensation assembly 100 and exchanges heat with the external air. After heat exchange, the water vapor in the steam condenses into liquid and is discharged or collected. The external air has its temperature increased after heat exchange with the steam at the condensation assembly 100, and convection occurs with the surrounding low-temperature gas, so that the heat-exchanged gas actively flows out of the air duct cover 200 from the air outlet channel. After the heat-exchanged air flows out of the air outlet channel, a negative pressure is formed at the air inlet channel. The air pressure at the air inlet channel is less than that at the air outlet channel, so that more gas enters the condensation assembly 100 from the air inlet channel and flows out from the air outlet channel, forming a directional air flow with a certain flow rate, accelerating the heat exchange efficiency between the air and the condensation assembly 100, and improving the condensation and cooling effect.

[0027] Optionally, in some embodiments of this embodiment, a check valve (such as a Tesla valve) is provided in the air inlet channel, the air outlet channel or the gas channel of the condensation assembly 100 to control the gas flow direction, ensure that the heat-exchanged air only flows out along the air outlet channel, and form a low-pressure area at the air inlet channel to attract the surrounding low-temperature air to enter and exchange heat with the condensation assembly 100, so as to achieve the purpose of improving the condensation effect.

[0028] Optionally, in some embodiments of this embodiment, an arc-shaped first guiding channel 401 is provided inside the air duct cover 200, and a second guiding channel 402 is formed between the inner side wall of the air duct cover 200 and the condensation assembly 100. The first guiding channel 401 and the second guiding channel 402 communicate with each other to form the air outlet channel.

[0029] Please refer to Figure 2As shown, in this embodiment, the air duct cover 200 is arranged in a funnel-shaped structure. An arc-shaped first guiding channel 401 is arranged inside the air duct cover 200, and the first guiding channel 401 communicates with the gas channel of the condensation assembly 100. At the same time, a second guiding channel 402 is formed at an interval between the inner side wall of the air duct cover 200 and the condensation assembly 100, and the second guiding channel 402 communicates with the first guiding channel 401. The first guiding channel 401 is arranged in an arc-shaped structure to change the gas flow direction in the exhaust duct, so that the air outlet of the exhaust duct can face the front or the side wall of the air duct cover 200. It should be noted that in this embodiment, the air duct cover 200 is arranged inside an external device, such as a steam box or a steam oven. Therefore, the heat-exchanged gas needs to be discharged outside the air duct cover 200 and the steam oven. The heat-exchanged air entering the inside of the steam oven may cause the temperature in the steam oven to be too high, resulting in damage to electronic components and affecting the service life of the steam box or the steam oven. Therefore, an exhaust port 1031 is not provided on the back of the air duct cover 200, but an arc-shaped first guiding channel 401 is arranged to change the gas flow direction, thereby adjusting the air outlet of the exhaust duct and controlling the discharge direction of the hot air.

[0030] Optionally, in some embodiments of this embodiment, the second guiding channel 402 is provided with an inclined guiding surface 201, and the gas passing through the second guiding channel 402 flows along the direction of the guiding surface 201, so that the airflow discharged from the exhaust duct forms an included angle with the airflow in the intake duct.

[0031] Please refer to Figure 2 As shown, in the air duct cover 200 provided in this embodiment, the inner side wall on at least one side is arranged at an interval from the condensation assembly 100 to form a second guiding channel 402. The inner side wall of the air duct cover 200 at the second guiding channel 402 is arranged in an inclined structure, thereby forming an inclined guiding surface 201. The airflow in the exhaust duct flows obliquely along the guiding surface 201 and flows out of the air duct cover 200. The direction of the outflowing airflow forms an included angle with the airflow direction in the intake channel, so that the outflowing hot air radiates in the inclined direction, preventing the hot air that has just flowed out from quickly returning to the intake duct and affecting the condensation effect of the condensation assembly 100.

[0032] Optionally, please refer to Figure 1 and Figure 2 As shown, in some embodiments of this embodiment, the air duct cover 200 is arranged in a funnel-shaped structure with one side open, and the two side walls of the air duct cover 200 form inclined guiding slopes. The condensation assembly 100 is arranged at the center of the air duct cover 200, and two exhaust ducts are formed on both sides of the air duct cover 200 and the condensation assembly 100. Please refer to Figure 2As shown, the external air enters the condensation assembly 100 from the middle of the air duct cover 200 for heat exchange, and after heat exchange, it is guided through the first guiding channel 401 and discharged from both sides of the air duct cover 200. On the one hand, the air is discharged from both sides of the air duct cover 200, which can make the air inlet and the air outlet located on the same side of the air duct cover 200, facilitating the installation of the air duct cover 200 on external equipment and preventing the discharged hot air from flowing into the interior of the external equipment and affecting the temperature of the external equipment. On the other hand, the symmetrically arranged exhaust channels on both sides can disperse the airflow after heat exchange, enabling the hot air after heat exchange to quickly mix with the cold air in the surrounding environment, preventing the airflow with higher heat from accumulating near the air duct cover 200 and affecting the condensation effect. At the same time, the dispersed airflow can reduce the gas flow on one side, preventing all the hot air after heat exchange from being discharged from one exhaust channel. It can be understood that the hot air discharged from the exhaust channel may directly spray onto the body part of the operator, easily making the operator feel uncomfortable. By setting symmetric exhaust channels on both sides to disperse the hot airflow and discharge it from an inclined direction, the hot air can be maximally prevented from directly jetting towards the user, improving the comfort of use. At the same time, the heat dissipation and condensation device provided in this embodiment forms an air inlet channel and an air outlet channel by changing the structure of the air duct cover 200 and adjusting the installation position of the condensation assembly 100. The structure is simple, without the need to separately set other structures, reducing production costs.

[0033] Optionally, in some embodiments of this embodiment, the condensation assembly 100 includes a condenser 101, an intake pipe 102, and a drain pipe 103. The intake pipe 102 is communicated with the inlet of the condenser 101, and the drain pipe 103 is communicated with the outlet of the condenser 101.

[0034] Please refer to Figure 1 As shown, in this embodiment, the air inlet channel and the air outlet channel are communicated with each other after passing through the condenser 101, and the condenser 101 can adopt any existing form of heat exchanger structure. Heat exchange structures such as heat exchange tubes and heat exchange fins are provided on the condenser 101, and the heat exchange tubes are respectively connected to the intake pipe 102 and the drain pipe 103. The intake pipe 102 is used to introduce steam into the condenser 101, and after heat exchange, the steam condenses and cools down to become a liquid and is discharged from the drain pipe 103.

[0035] Optionally, in some embodiments of this embodiment, an exhaust port 1031 is provided on the drain pipe 103, and the exhaust port 1031 is communicated with the exhaust channel.

[0036] Please refer to Figure 1 As shown, an exhaust port 1031 communicating with the exhaust channel is provided on the drain pipe 103. It can be understood that there are still other uncondensed gases (mainly air) after partial gas in the steam condenses. These gases can be quickly discharged directly from the exhaust port 1031 and discharged from the air duct cover 200 together with the mixed heat exchange gas in the exhaust channel.

[0037] Optionally, in some embodiments of the present embodiment, a baffle 500 is provided at the opening of the air duct cover 200. A cold air inlet 501 and a hot air outlet 502 are provided on the baffle 500. The cold air inlet 501 is communicated with the air inlet passage, and the hot air outlet 502 is communicated with the air outlet passage.

[0038] Please refer to Figure 1 As shown, in this embodiment, the baffle 500 is used to protect the internal condensation assembly 100 from being damaged by external impact. A cold air inlet 501 communicating with the air inlet passage is provided in the middle of the baffle 500. At the same time, cold air outlets communicating with the air outlet passage are provided on both sides of the baffle 500. It can be understood that in this embodiment, an air outlet passage is formed through the gap between the condensation assembly 100 and the inner side wall of the air duct cover 200 in the air duct cover 200. Such a setting can form a relatively large air inlet area at the air inlet end of the condensation assembly 100, and attract the air flow in the air inlet area to flow through the condensation assembly 100 quickly through the heat convection effect. When discharging gas, the gas in the air outlet passage flows out obliquely, has little influence on the air inlet area, mixes with the gas farther away to cool down and then returns to the air inlet area, forming a virtuous cycle. Therefore, only by providing a cold air inlet 501 at the corresponding position on the baffle 500 and hot air outlets 502 on both sides, it is ensured that the air after heat exchange flows out of the air duct cover 200, avoiding the mixing of hot air and cold air in the air inlet passage in the air duct cover 200 and improving the heat exchange effect. Optionally, protection nets are provided at both the cold air inlet 501 and the hot air outlet 502. The protection nets can prevent external foreign objects or animals from entering the interior of the air duct cover 200, avoiding damage to internal components or affecting the condensation effect.

[0039] Optionally, in some embodiments of the present embodiment, a fan 300 is provided inside the air duct cover 200, and the fan 300 is located in the air inlet passage.

[0040] Please refer to Figure 1 and Figure 2 As shown, a fan 300 is provided in the air inlet passage. The fan 300 can accelerate the flow rate of the gas, enabling the unheated cold air to quickly exchange heat with the condensation assembly 100. At the same time, setting the fan 300 to accelerate the gas flow can enable the gas in the air outlet passage to flow out of the air duct cover 200 quickly along the inclined guide surface 201 and spray a relatively long distance, avoiding the directly flowing back of the gas after heat exchange into the air duct cover 200 and affecting the heat exchange effect.

[0041] Embodiment 2

[0042] This embodiment provides a steam oven, which includes a steam oven main body and the above-mentioned heat dissipation and condensation device. The heat dissipation and condensation device is arranged on the steam oven main body, and the steam pipeline of the steam oven main body is communicated with the condensation assembly 100 of the heat dissipation and condensation device.

[0043] In this embodiment, the air duct cover 200 of the heat dissipation and condensation device is installed inside the main body of the steam oven, facilitating connection to the heat dissipation component in the heat dissipation and condensation device through a pipeline, thereby reducing the steam generated by the main body of the steam oven and delivering it to the condensation component 100. In addition to protecting the internal components, the baffle 500 of the heat dissipation and condensation device can also play a role in installation and fixation. The baffle 500 can be provided with screw holes, and the baffle 500 can be fixed to the outer shell of other devices by cooperating with screws, thereby realizing the installation and fixation of the heat dissipation and condensation device.

[0044] Optionally, in some embodiments of this embodiment, the side wall of the air duct cover 200 in the heat dissipation and condensation device is provided with an air inlet through hole 202. The exhaust duct in the heat dissipation and condensation device communicates with the inside of the main body of the steam oven through the air inlet through hole 202, and the orifice of the air inlet through hole 202 on the side close to the exhaust duct is arranged towards the exhaust port of the exhaust duct.

[0045] Please refer to Figure 1 As shown in the figure, in this embodiment, the air duct cover 200 is located inside the main body of the steam oven. A plurality of air inlet through holes 202 are provided on the side wall of the air duct cover 200, so that the air duct cover 200 communicates with the inside of the main body of the steam oven. The air inlet through holes 202 are arranged obliquely along the gas flow direction in the exhaust duct, so that the orifice of the air inlet through hole 202 faces the exhaust port of the exhaust duct. When the heat dissipation and condensation device works, the exhaust duct flows along the side wall provided with the air inlet through holes 202. Since the air inlet through holes 202 are arranged obliquely along the gas flow direction, it can prevent the flowing gas from entering the inside of the main body of the steam oven through the air inlet through holes 202. When the gas flows, due to the increase in flow velocity and the decrease in pressure, the air inside the main body of the steam oven flows towards the low-pressure area, thereby passing through the air inlet through holes and entering the exhaust duct, and being discharged along with the exhaust duct. The heat dissipation and condensation device provided in this embodiment can not only condense the steam generated by the steam oven, but also accelerate the gas flow inside the main body of the steam oven, playing a role in assisting heat dissipation and cooling.

[0046] In summary, the embodiment of the present utility model provides a heat dissipation and condensation device, which includes: a condensation component 100 and an air duct cover 200. The air duct cover 200 has an air inlet channel and an exhaust duct. The condensation component 100 is arranged at the connection of the air inlet channel and the exhaust duct. External gas flows through the condensation component 100 through the air inlet channel, exchanges heat with the steam in the condensation component 100, and is discharged from the exhaust duct to form a directional air flow, and the air pressure at the air inlet channel is less than the air pressure at the exhaust duct. The high-temperature steam generated by devices such as a steam oven is cooled and condensed by using the air flow, so that the moisture in the steam is condensed, collected and discharged. By providing an air inlet channel and an exhaust duct in the air duct cover 200, and exchanging heat between the steam and the external air through the condensation component 100, the external gas is heated and flows to form a directional air flow, thereby accelerating the air flowing through the condensation component 100 and improving the heat dissipation and condensation effect.

[0047] The embodiment of the present utility model further provides a steam oven, which includes a steam oven main body and the above-mentioned heat dissipation and condensation device. An air inlet through hole 202 is formed in the side wall of the air duct cover 200 in the heat dissipation and condensation device. The exhaust air duct in the heat dissipation and condensation device is communicated with the inside of the steam oven main body through the air inlet through hole 202. The orifice of the air inlet through hole 202 close to the exhaust air duct is arranged towards the air outlet of the exhaust air duct. By adopting the above-mentioned heat dissipation and condensation device to condense and collect the steam generated by the steam oven, it is possible to prevent the steam from being directly discharged into the kitchen and condensing on electrical appliances or kitchen utensils, avoiding damage to household appliances and furniture. At the same time, avoiding direct steam discharge can reduce the humidity in the kitchen, prevent kitchen utensils from growing mold due to moisture, and improve the use safety and comfort.

[0048] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
