Description

Technical Field

[0001] This utility model relates to the field of steam oven technology, specifically to a steam oven with good steam emission and cooling effect. Background Technology

[0002] A steam oven is a device that combines steaming and baking functions. Compared to traditional ovens, it offers the added benefit of steam cooking, making it increasingly popular. However, during operation, the oven cavity generates high-temperature, high-humidity gas. As new steam is continuously produced, this exhaust gas is typically expelled through the vent at the top of the oven. However, due to the rapid release of the steam and its high heat, this exhaust gas often fails to dissipate quickly enough, remaining hot upon exiting the oven. This can easily cause burns to users, posing a safety hazard. Furthermore, steam ovens are usually installed below the kitchen stove, with the vent positioned directly at leg level. If the exhaust gas doesn't dissipate heat effectively, hot air can blow directly onto the user's legs, creating a poor user experience.

[0003] Therefore, it is necessary to improve upon existing technologies to provide a steam oven that can dissipate heat from high-temperature and high-humidity exhaust gases in a timely manner and has a good cooling effect. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] 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.

[0024] 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. 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.

[0025] refer to Figure 1-5 This utility model provides a steam oven with good steam exhaust cooling effect, including a steam oven cavity 1 (i.e., a cavity is provided inside the main body of the oven, which is mainly used to place food during the cooking process), and an air duct seat 2, a condenser 3, and a cooling fan 4 located on the top of the steam oven cavity 1; Reference Figure 5The air duct seat 2 is equipped with a cooling chamber 22, and the condenser 3 is located in the cooling chamber 22, which is divided into an upper chamber 220 and a lower chamber 221. The cooling fan 4 is located on one side of the air duct seat 2, and the cooling fan 4 is equipped with an air outlet 40 facing the upper chamber 220. An exhaust port 23 is opened on the other side of the air duct seat 2, and the upper chamber 220 and the lower chamber 221 can be connected to the exhaust port 23 respectively. The air outlet 40 of the cooling fan 4, the upper chamber 220 and the exhaust port 23 are connected in sequence. That is, the air blown out by the cooling fan 4 will first be cooled by the condenser 3, and then discharged through the exhaust port 23. This can cool the high temperature and high humidity exhaust gas in time, and avoid the airflow discharged from the exhaust port 23 being too hot and causing burns.

[0026] The steam oven provided by this utility model, during use, the high-temperature and high-humidity exhaust gas in the oven cavity first enters the lower cavity 221, fully contacts the condenser 3, and is cooled. By the time it reaches the upper cavity 220, it has already achieved a preliminary cooling effect. As the cooling fan 4 operates, the air outlet 40 of the cooling fan 4 continuously blows air towards the upper cavity 220. Since the air outlet 40, the upper cavity 220, and the exhaust port 23 are sequentially connected, when the fan blows air towards the upper cavity 220, the exhaust gas can be discharged to the outside through the exhaust port 23. (See reference...) Figure 5 , Figure 5 The direction indicated by the middle arrow is the direction of exhaust gas flow; after being cooled by the condenser 3, the temperature of the exhaust gas at the exhaust port 23 is greatly reduced, thus having a good cooling effect on the generated high-temperature and high-humidity exhaust gas and improving the user experience.

[0027] refer to Figure 1-3 In a preferred embodiment, the top of the steam oven cavity 1 is also provided with a steam generator 5, which is mainly used to release high-temperature gas into the oven cavity, thereby realizing the oven's micro-steaming function; the condenser 3 is provided with a water inlet 30, a water outlet 31, and a water passage 32 connecting the water inlet 30 and the water outlet 31; Reference Figure 3 The water inlet 30 of the steam generator 5 is connected to the water outlet 31 of the condenser 3, and the steam outlet of the steam generator 5 is connected to the steam oven cavity 1. In this embodiment, the water flow in the condenser 3 achieves a heat exchange effect, thereby cooling the high-temperature and high-humidity exhaust gas. Specifically, cold water flows in the condenser 3. When the high-temperature and high-humidity exhaust gas enters the cooling chamber 22, the cold water in the water channel 32 absorbs the heat of the high-temperature exhaust gas using the principle of heat exchange, thereby turning the high-temperature exhaust gas into low-temperature exhaust gas, which is then discharged to the outside through the exhaust port 23. At the same time, the cold water that has absorbed heat rises in temperature after absorbing heat and flows into the steam generator 5 for further heating and evaporation, improving the steam oven's operating capacity, achieving a recycling effect, and also saving more energy.

[0028] refer to Figure 1-3 In a further preferred embodiment, a water storage tank 6 and a water pump 7 are connected to each other at the top of the steam oven cavity 1. The outlet 31 of the water storage tank 6 is connected to the inlet 30 of the condenser 3. The water pump 7 is used to transport the medium (such as cold water) in the water storage tank 6 to the steam generator 5 through the condenser 3. The water pump 7 draws the cold water in the water storage tank 6 into the water flow channel of the condenser 3 to achieve water circulation and improve the heat exchange effect of the condenser 3.

[0029] refer to Figure 3 In a preferred embodiment, there are multiple water channels 32, which are spaced apart along the length of the condenser 3. Connecting pipes 33 are provided on both sides of the condenser 3, allowing adjacent water channels 32 to be connected. The multiple water channels 32 further accelerate the heat exchange efficiency of the condenser 3, ensuring timely cooling of the high-temperature exhaust gas and preventing it from being discharged before it has had time to cool. Furthermore, the timely cooling of the exhaust gas prevents discomfort to the user, thus reducing restrictions on the installation location of the steam oven.

[0030] refer to Figure 3 and 4 In a preferred embodiment, the flow direction of the water channel 32 is perpendicular to the airflow direction of the air outlet 40 of the cooling fan 4. For example... Figure 3 and 4 As shown, with Figure 3 From a first-person perspective, the direction of water flow within waterway 32 ( Figure 3 The direction indicated by the middle arrow is the direction of water flow, and the direction of air outlet 40 of the cooling fan 4 is the direction of air outlet 40. Figure 4 The direction indicated by the middle arrow is perpendicular to the air outlet direction. Here, "perpendicular" refers to a relatively perpendicular state; in actual operation, it may not be perfectly perpendicular. This ensures more uniform heat exchange on the surface of condenser 3, resulting in better heat exchange performance.

[0031] In a preferred embodiment, the condenser 3 is a finned condenser 3. The finned condenser 3 can increase the contact area between the condenser 3 and the high-temperature exhaust gas, further improving the heat exchange efficiency and simultaneously accelerating the cooling rate of the high-temperature exhaust gas.

[0032] refer to Figure 2 and 5In a preferred embodiment, the air duct base 2 includes a base 20 and a cover 21, which are connected to form a cooling chamber 22; the base 20 and the cover 21 are detachably connected. Since the condenser 3 is located inside the cooling chamber 22, the detachable connection between the base 20 and the cover 21 facilitates the later inspection and maintenance of the condenser 3 or the equipment.

[0033] refer to Figure 1-3 In a preferred embodiment, a guide member 24 is provided at one end of the duct seat 2 near the exhaust port 23. Multiple guide members 24 are provided, spaced apart along the length of the duct seat 2, thus dividing the exhaust port 23 into multiple exhaust channels (e.g., Figure 1 As shown, the exhaust vent 23 is divided into multiple channels by the guide member 24; the guide member 24 is located on the base 20 or on the cover 21. The guide member 24 mainly serves to guide the exhaust gas emission. The guide member 24 can be located on the base 20 or on the cover 21. Specifically, when the guide member 24 is located on the base 20, one end is connected to the base 20, and the other end protrudes upward relative to the base 20 (that is, towards the cover 21) and abuts against the cover 21; similarly, when the guide member 24 is located on the cover 21, one end is connected to the cover 21, and the other end protrudes downward relative to the cover 21 (that is, towards the base 20) and abuts against the base 20, thereby serving to divert and guide the exhaust gas at the exhaust vent 23.

[0034] refer to Figure 2 In a preferred embodiment, the guide member 24 is integrally formed with the base 20 or the cover 21. This integral forming design increases the overall strength and makes it less prone to damage.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
