Description

Technical Field

[0001] This utility model relates to the technical field of steaming and baking equipment, specifically to a cooling device and a steam oven. Background Technology

[0002] A steam oven is a kitchen appliance that combines steaming and baking functions. It adds a heating element to a steam oven for heating and baking food. A water-boiling evaporation tray is located at the bottom, where water is heated directly to heat the food.

[0003] When a user uses the steam oven, the hot air generated inside the oven cavity is forced out of the external environment by the cooling fan through the air duct. The hot air can also be blown out from the gaps in the control panel and door assembly of the steam oven.

[0004] However, in the relevant hot air blowing technology of steam ovens, the hot air is blown out of the air duct of the steam oven at a high speed and with little heat dissipation, resulting in the hot air being very hot when it is blown out to the outside, which poses a risk of burns; moreover, when the hot air contains a lot of vapor (for example, when the steam oven is turned on), due to its high temperature, it is easy to condense into water droplets when it comes into contact with objects with a lower temperature after being blown out to the outside. Utility Model Content

[0005] In view of the above-mentioned defects in the prior art, the present invention provides a cooling device to solve at least one of the above-mentioned technical defects in the prior art. It can make the temperature of the hot air from the steam oven blown out of the air duct lower, avoid scalding people, improve safety, and prevent water droplets from condensing even when it encounters objects with low temperature.

[0006] The second aspect of this utility model provides a steam oven.

[0007] To achieve the objective of this utility model, a cooling device is provided, comprising:

[0008] A heat exchanger having an air inlet and an air outlet is provided in the air duct and is suitable for cooling the hot air in the air duct.

[0027] The beneficial effects of this utility model are as follows: The cooling device provided by this utility model cools the heat exchanger by setting the heat exchanger in the air duct of the steam oven and setting a radiator, liquid inlet pipe, liquid outlet pipe and drive pump to form a cooling circulation system. This allows the heat of the heat exchanger located in the air duct to be absorbed, thereby enabling the heat exchanger to cool the hot air generated by the steam oven. This makes the temperature of the hot air blown out of the steam oven lower, avoiding burns and improving safety. Moreover, even if the hot air contains a lot of vapor and encounters a low-temperature object, it is not easy to condense into water droplets.

[0047] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0048] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this applies. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0050] The following is combined Figures 1 to 7 The embodiments of this utility model will be described below. It should be understood that the following description is merely an illustrative embodiment of this utility model and does not constitute any limitation on this utility model.

[0051] Steam ovens typically have a cavity 1 and an air duct 2. The air duct 2 is connected to the cavity 1, and the hot air generated in the cavity 1 can be discharged to the outside environment through the air duct 1.

[0052] An embodiment of this utility model provides a cooling device, which includes a heat exchanger 100, a radiator 200, an inlet pipe 300, an outlet pipe 400, and a drive pump 500.

[0053] The heat exchanger 100 has an air inlet 110 and an air outlet 120. The heat exchanger 100 is installed in the air duct 2. The hot air in the air duct 2 can enter the heat exchanger 100 from the air inlet 110 and be discharged from the air outlet 120, so that the heat exchanger 100 can cool the hot air in the air duct 2, so that the hot air can be cooled to form low temperature and low humidity exhaust gas before being discharged into the external environment.

[0054] The radiator 200 contains coolant, enabling it to cool the heat exchanger 100.

[0055] The liquid inlet pipe 300 connects the radiator 200 and the heat exchanger 100. In this embodiment, the first end of the liquid inlet pipe 300 is connected to the radiator 200, and the second end of the liquid inlet pipe 300 is connected to the heat exchanger 100, so that the liquid inlet pipe 300 can input the coolant of the radiator 200 into the heat exchanger 100 to cool the heat exchanger 100, thereby enabling the cooled heat exchanger 100 to cool the hot air.

[0056] The outlet pipe 400 connects the heat exchanger 100 and the radiator 200. In this embodiment, the first end of the outlet pipe 400 is connected to the heat exchanger 100, and the second end of the outlet pipe 400 is connected to the radiator 200, so that the outlet pipe 400 can output the coolant after cooling the heat exchanger 100 to the radiator 200 to realize the recovery of coolant.

[0057] The drive pump 500 drives the coolant to circulate. In other words, the drive pump 500 can drive the coolant to circulate sequentially between the radiator 200, the inlet pipe 300, the heat exchanger 100, the outlet pipe 400, and the radiator 200 to form a cooling circulation system, thereby enabling the radiator 200 to cool the heat exchanger 100. Of course, this cooling circulation system can be a closed cooling water circuit, which can eliminate the risk of the circulation system being blocked due to external impurities.

[0058] Of course, in this embodiment, the coolant can be water, the inlet pipe 300 can be a water inlet pipe, the outlet pipe 400 can be a water outlet pipe, and the drive pump 500 can be a water pump, so as to save the manufacturing cost of the cooling device.

[0059] It is understood that the cooling device provided in the embodiments of this utility model cools the heat exchanger 100 by setting the heat exchanger 100 in the air duct 2 of the steam oven and setting the radiator 200, the liquid inlet pipe 300, the liquid outlet pipe 400 and the drive pump 500 to form a cooling circulation system. This allows the heat of the heat exchanger 100 located in the air duct 2 to be absorbed, thereby enabling the heat exchanger 100 to cool the hot air generated by the steam oven. This makes the temperature of the hot air from the steam oven lower when it is blown out of the air duct 2, avoiding burns and improving safety. Moreover, even if the hot air has a high vapor content and encounters a low-temperature object, it is not easy to condense into water droplets.

[0060] Furthermore, combined Figures 1 to 3 In order to improve the efficiency of hot air exhaust in the steam oven, in some embodiments of this utility model, the cooling device further includes a convection fan 600. The convection fan 600 is located at the air inlet 110 of the heat exchanger 100, which can draw the hot air from the air duct 2 into the heat exchanger 100. The hot air comes into contact with the heat exchanger 100 for heat exchange, and the heat exchanger 100 cools down the hot air. The cooled hot air flows out of the heat exchanger 100 from the air outlet 120 under the action of the convection fan 600, and is discharged into the external environment through the air duct 2.

[0061] In addition, combined Figures 1 to 3 In order to simplify the structure of the cooling device and thus save costs, in a specific embodiment of the present invention, the liquid outlet pipe 400 includes a first liquid outlet pipe 410 and a second liquid outlet pipe 420.

[0062] The drive pump 500 is located between the first liquid outlet pipe 410 and the second liquid outlet pipe 420. The first end of the first liquid outlet pipe 410 is connected to the heat exchanger 100, and the second end of the first liquid outlet pipe 410 is connected to the drive pump 500. The first end of the second liquid outlet pipe 420 is connected to the drive pump 500, and the second end of the second liquid outlet pipe 420 is connected to the radiator 200. This allows the coolant after heat exchange with the heat exchanger 100 to be driven by the drive pump 500 to the radiator 200 for heat dissipation and cooling, thereby removing the heat from the heat exchanger 100 and enabling the heat exchanger 100 to continuously cool the hot air in the air duct 2.

[0063] Of course, combined Figure 1 and Figure 3 In some embodiments of this utility model, the cooling device further includes a cooling fan 700, which is located next to the radiator 200 and can cool the radiator 200, so that the heat on the radiator 200 can be dissipated to the external environment more quickly, thus ensuring the cooling effect of the radiator 200 on the heat exchanger 100.

[0064] Combination Figure 6In some embodiments of this invention, the heat exchanger 100 of the cooling device is provided with a snake-shaped liquid pipe having an inlet and an outlet.

[0065] The liquid inlet pipe 300 is connected to the inlet. That is, the first end of the liquid inlet pipe 300 is connected to the radiator 200, and the second end of the liquid inlet pipe 300 is connected to the inlet of the snake-shaped liquid pipe in the heat exchanger 100, so that the liquid inlet pipe 300 can input the coolant of the radiator 200 into the snake-shaped liquid pipe in the heat exchanger 100 to achieve cooling of the heat exchanger 100.

[0066] The outlet pipe 400 is connected to the outlet. That is, the first end of the outlet pipe 400 is connected to the outlet of the snake-shaped liquid pipe in the heat exchanger 100, and the second end of the outlet pipe 400 is connected to the radiator 200, so that the outlet pipe 400 can output the coolant after cooling the heat exchanger 100 to the radiator 200 to realize the recovery of coolant.

[0067] The snake-shaped liquid pipe increases the contact area between the coolant and the heat exchanger 100, thereby improving the cooling efficiency and effect of the heat exchanger 100.

[0068] In addition, combined Figure 1 In some embodiments of this utility model, multiple vertical grooves 130 are provided on both sides of the heat exchanger 100. The multiple vertical grooves 130 can increase the surface area of ​​the heat exchanger 100, increase the contact area between the hot air in the air duct 2 and the heat exchanger 100, thereby improving the cooling efficiency and effect of the heat exchanger on the hot air.

[0069] Furthermore, combined Figure 1 In some embodiments of this utility model, a first vertical groove 131 is provided on the first side of the heat exchanger 100, and a second vertical groove 132 is provided on the second side of the heat exchanger 100.

[0070] The first vertical groove 131 has a serpentine opening, which can increase the passage and contact surface of the hot air in the air duct 2 through the heat exchanger 100, so that the hot air can fully contact the heat exchanger 100 to dissipate heat, thereby reducing the temperature of the hot air.

[0071] The second vertical groove 132 is upright, which increases its surface area and allows the air generated by the convection fan 600 to pass through quickly, thereby quickly removing the heat from the heat exchanger 100 and improving the cooling efficiency of the cooling device.

[0072] Combination Figures 2 to 6 In some embodiments of this utility model, the steam oven includes an air duct cover and an air duct seat, wherein the air duct cover and the air duct seat form the air duct 2, and the hot air generated inside the steam oven can be discharged to the outside environment through the air duct 2.

[0073] The heat exchanger 100 is installed on the air duct seat, which can separate the air duct 2 formed by the air duct cover and the air duct seat, and play a role in separating the hot air gas generated by the steam oven cavity and the gas blown out by the convection fan 600, thereby improving the cooling effect.

[0074] Of course, combined Figure 2 and Figure 3 In some embodiments of this utility model, the cooling device further includes a condensate recovery pipe 800, which connects the air duct 2 of the steam oven to the cavity 1 of the steam oven. This allows the cooling device to collect the moisture condensed from the hot air generated by the steam oven and return it to the cavity 1 of the steam oven via the condensate recovery pipe 800 for secondary heating and evaporation. In other words, even if a large amount of hot air (i.e., steam) from the steam oven is blown into the external environment, the moisture in the steam can be recovered through the condensate recovery pipe 800, thus improving the operating time of the steam oven's water tank. This eliminates the need for frequent water replenishment or the installation of a large-capacity water tank, ensuring longer operating time, improving user experience, and conserving the structural space of the steam oven.

[0075] Combination Figures 1 to 7 In an embodiment of this utility model, a steam oven is also provided, which includes the cooling device and the steam oven body 3 described above.

[0076] The main body 3 of the steam oven has a cavity 1 and an air duct 2. The air duct 2 connects the cavity 1 with the external environment. The heat exchanger 100 in the cooling device is installed on the air duct 2. After the hot air generated by the cavity 1 of the steam oven enters the air duct 2, it can exchange heat with the heat exchanger 100 in the air duct 2, so that the temperature of the hot air is reduced before it is discharged to the external environment.

[0077] It is understood that the steam oven provided in the embodiments of this utility model, having included the aforementioned cooling device, necessarily possesses all the advantages of that cooling device. That is, the hot air generated by the steam oven is cooled, so that the temperature of the hot air blown out of the steam oven from the air duct 2 is lower, avoiding burns and improving safety. Moreover, even if the hot air has a high vapor content and encounters a low-temperature object, it is not easy for it to condense into water droplets.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.
