[0002] Currently, the operating temperatures of cooking products such as steamers, ovens, and steam ovens on the market are mostly between 40 degrees Celsius and 320 degrees Celsius. Such high operating temperatures will inevitably have an impact on the electronic components of the products.

[0003] The researchers used thermal insulation cotton on the outside of the steam oven inner tank to isolate the heat, reduce heat transfer, protect surrounding components, and make the temperature rise of most components meet the requirements of national standards. However, the surface temperature rise of some components in special positions, such as lighting, which are not well isolated by thermal insulation cotton, is still very high. Long-term use at high temperature will shorten the service life of the components, thereby directly reducing the overall service life of the product.

[0004] Common heat dissipation methods include radiation, conduction, convection and evaporation. Radiation, conduction and evaporation will occupy a considerable amount of space when used at high temperatures, and have complex structures, high costs and unsatisfactory heat dissipation effects.

[0040] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0041] The terms "a", "an", "the", "" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0042] A steam oven according to an embodiment of the utility model comprises an inner container 1, a component assembly 2, an air guide cover 3, an air guide structure 4, and a fan 5. The component assembly 2 is installed on the outer side of the inner container 1, the air guide cover 3 is covered on the top of the inner container 1, the fan 5 is arranged at the air inlet end of the air guide cover 3, the air outlet end of the fan 5 is connected to the air inlet end of the air guide cover 3, the air guide cover 3 is provided with a relatively independent first air guide channel and a second air guide channel 30, the first air guide channel is connected to the exhaust end of the inner container 1, and the steam discharged from the inner container 1 can enter the first air guide channel , so as to discharge the steam of the inner pot 1 to the outside of the steam oven; one end of the air guide structure 4 is connected to the air outlet end of the second air guide channel 30, and the other end corresponds to the component assembly 2, so as to guide the airflow entering the second air guide channel 30 to the component assembly 2; the air outlet end of the fan 5 is connected to the first air guide channel and the second air guide channel 30 at the same time, wherein part of the airflow blown by the fan 5 enters the first air guide channel to take away the steam discharged from the inner pot 1; the other part of the airflow blown by the fan 5 is blown to the component assembly 2 through the second air guide channel 30 and the air guide structure 4. The high-speed airflow blown by the fan 5 can form a negative pressure state in the air guide cover 3, so that the steam entering the first air guide channel is discharged, and the airflow entering the second air guide channel 30 is quickly blown to the component assembly 2, so as to achieve heat dissipation of the component assembly 2. Since the first air guide channel and the second air guide channel 30 are relatively independent, the steam only enters the first air guide channel and is blown out by the fan 5, and there is no steam in the second air guide channel 30, only part of the airflow blown out by the fan 5, so that the steam can be prevented from entering the air guide structure 4 to affect the heat dissipation and service life of the component assembly 2. The air guide structure 4 in the present application can be an air guide pipe 41, or other air guide components, as long as it can guide the airflow in the second air guide channel 30 to the component assembly 2, and the present application does not make any restrictions here.

[0043] The present application provides two relatively independent first air guide channels and second air guide channels 30 on the fan cover 3 to guide part of the airflow formed by the fan 5 to the component assembly 2. The airflow directly acts on the surface of the component assembly 2 with high temperature rise, which can take away the heat of the component assembly 2, achieve the effect of cooling the component assembly 2, and solve the heat dissipation problem of the component assembly 2. The present application can effectively dissipate heat for the component assembly 2 that originally has an unsatisfactory heat dissipation effect, and improve the service life of the product. The component assembly 2 of the present application is various circuit boards of a steam oven, such as a lighting lamp, a heating tube, etc. Taking a lighting lamp as an example, the lamp body of a general lighting lamp is installed on the inner side of the inner tank 1, and the circuit board of the lighting lamp is connected to the outer side of the inner tank 1. It is proved by experiments that the above structure can reduce the temperature of the lighting lamp circuit board from 136 degrees Celsius to 96 degrees Celsius, that is, the airflow directly acting on the surface of the component assembly 2 can reduce the temperature by about 40 degrees, and the present application solves the high temperature rise problem of the component assembly 2 that cannot be handled by the heat insulation method of heat insulation cotton with the smallest space and the lowest cost. According to the above, it can be known that the present application can not only reduce the temperature of the cavity, but also fully utilize the fan 5 and the air guide cover 3 to cool the surface of the component assembly 2.

[0044] In a preferred embodiment of the present invention, Figure 1-4 The component assembly 2 shown includes a shell 20 and a component 21 installed in the shell 20. A heat dissipation cavity is formed between the shell and the component 21. The shell 20 is provided with an air inlet and a first heat dissipation hole 201 connected to the heat dissipation cavity. The other end of the air guide structure 4 is connected to the air inlet. In this way, part of the airflow blown out by the fan 5 can enter the heat dissipation cavity through the second air guide channel 30 and the air guide structure 4 and be discharged from the first heat dissipation hole 201, so that the airflow and the component 21 are fully in contact, effectively reducing the temperature of the component 21, and achieving the effect of cooling and dissipating heat for the component 21. In addition, it is only necessary to install the shell 20 on the side of the inner tank 1, which has a simple structure and low cost.

[0045] In a preferred embodiment of the present invention, Figure 1-4The air guide cover 3 shown includes a first air inlet 300, a first air outlet 301, a second air inlet 302 and a second air outlet 303. The first air inlet 300 and the first air outlet 301 are connected to form a first air guide channel; the second air inlet 302 and the second air outlet 303 are connected to form a second air guide channel 30; wherein, the first air inlet 300 and the second air inlet 302 are both connected to the air outlet end of the fan 5, one end of the air guide structure 4 is connected to the second air outlet 303, and the other end of the air guide structure 4 is connected to the air inlet. The airflow blown out by the fan 5 enters the first air guide channel and the second air guide channel 30 respectively, which can not only discharge the steam discharged by the inner tank 1, but also dissipate heat and cool down the components 21. Since the first air guide channel and the second air guide channel 30, the second air guide channel 30 is directly connected to the fan 5 and the air guide structure 4 to prevent the steam from condensing into water droplets and reaching the surface of the components 21 to cause a short circuit, which can extend the service life of the product. At the same time, only the air guide structure 4 needs to be added between the air guide cover 3 and the components 21, and the original structure of the steam oven does not need to be changed, which is low in cost and simple to operate. Figure 1-4 The steam oven shown also includes an air guide cavity 6, which is arranged between the air guide cover 3 and the inner pot 1. The air guide cavity 6 is spaced apart from the air guide cover 3 and / or the inner pot 1 to form a first air inlet 300. A partition assembly 61 is provided in the air guide cavity 6 to divide the air guide cavity 6 into a steam cavity 62 and an air guide cavity 63. The steam inlet of the steam cavity 62 is connected to the exhaust end of the inner pot 1, and the steam outlet of the steam cavity 62 is connected to the first air guide channel. The two ends of the air guide cavity 63 are respectively connected to the second air inlet 302 and the second air outlet 303 to form a second air guide channel 30. The air guide cavity 6 is spaced apart from the air guide cover 3 and / or the inner pot 1 to form the first air inlet 300, which can be divided into three different situations: the first is that the air guide cavity 6 can be as follows Figure 2-3 The top shown is connected to the air guide cover 3, and there is a gap between the bottom of the air guide cavity 6 and the top of the inner liner 1 to form a first air inlet 300; the second, the bottom of the air guide cavity 6 can be connected to the inner liner 1, and there is a gap between the top of the air guide cavity 6 and the air guide cover 3 to form the first air inlet 300; there is another situation that the two sides of the air guide cavity 6 are connected to the air guide cover 3, and the top and bottom of the air guide cavity 6 are respectively spaced from the air guide cover 3 and the inner liner 1 to form the first air inlet 300, so that the airflow discharged by the fan 5 can be accelerated at the first air inlet 300, and the high-speed airflow can form a negative pressure in the first air guide channel, so that the steam can be smoothly discharged to the outside of the air guide cover 3. In addition, it is only necessary to set a partition assembly 61 inside the air guide cavity 6 so that the air guide cover 3 has two independent first air guide channels and second air guide channels 30, which is simple in structure, convenient for processing and low in cost.

[0046] In a preferred embodiment of the present invention, the steam outlet of the steam chamber 62 is arranged on the horizontal wall of the steam chamber 62. The steam outlet 621 is connected to the first air inlet 300 so that the steam is carried out of the steam oven by the high-speed airflow.

[0047] In a preferred embodiment of the present invention, Figure 1-4 The outer periphery of the second air inlet 302 is provided with a baffle 31, and the baffle 31 extends from the second air inlet 302 toward the direction of the fan 5. When the steam oven is working, if the amount of steam is large, it is easy to flow back toward the fan 5. The baffle 31 is arranged around the outer periphery of the second air inlet 302, and the free end of the baffle 31 can be inserted into the air outlet of the fan 5, which can effectively prevent the steam from entering the second air guide channel 30. Preferably, a protruding portion 32 protruding outward is provided on the side of the air guide cover 3 close to the fan 5, and the protruding portion 32 is connected to the top of the air outlet of the fan 5. The baffle 31 is inserted into the air outlet of the fan 5 to block the steam that may flow back, prevent the steam from entering the second air guide channel 30, and affect the heat dissipation and service life of the components 21.

[0048] In a preferred embodiment of the present invention, Figure 1-4 The partition assembly 61 shown includes a first partition 611, a second partition 612 and a third partition 613, one end of the first partition 611 is connected to the side of the air guide cavity 6 close to the second air inlet 302, the other end of the first partition 611 extends to the inside of the air guide cavity 6, one end of the second partition 612 is connected to the other end of the first partition 611, the other end of the second partition 612 extends in the direction of the second air outlet 303, one end of the third partition 613 is connected to the other end of the second partition 612, and the other end of the third partition 613 extends along the air inlet direction and connects to the inner wall of the air guide cavity 6; wherein, the ventilation area of ​​the second air guide channel 30 gradually decreases along the air flow direction through the first partition 611, the second partition 612 and the third partition 613. The purpose of this design is to use the partition assembly 61 to change the direction of the airflow in the second air guide channel 30, and at the same time reduce the area of ​​the air outlet of the second air guide channel 30, so as to ensure that the airflow can have a certain speed when blowing towards the component 21, and effectively reduce the surface temperature of the component 21. In addition, the plate assembly 61 increases the contact area with the gas, thereby cooling the gas blown in by the fan 5 , and effectively reducing the surface temperature of the component 2 under the action of high flow rate and low airflow, thereby achieving the purpose of heat dissipation for the component 21 .

[0049] Preferably, the connection between the first baffle 611 , the second baffle 612 and the third baffle 613 is configured to be arc-shaped to reduce the loss of airflow transitioning from the first air guide plate 3251 to the second air guide plate 3252 .

[0050] In a preferred embodiment of the present invention, Figure 1-4The partition assembly 61 shown also includes a fourth partition 614, one end of the fourth partition 614 is connected to the third partition 613, and the other end of the fourth partition 614 is connected to the side of the air guide cavity 6 close to the second air outlet 303. This design allows the gas entering the second air guide channel 30 to quickly enter the air guide structure 4, thereby increasing the speed of the airflow entering the air guide structure 4.

[0051] In addition, the fourth partition plate 614 , the third partition plate 613 and the air guide cavity 63 are used to form an insulating cavity, which can effectively block the heat transfer of steam toward the second air guide channel 30 .

[0052] In a preferred embodiment of the present invention, Figure 1-4 The first heat dissipation hole 201 is provided on the side wall of the housing 20 away from the inner liner 1. The gas blown out of the air guide structure 4 is discharged from the housing 20 through the mounting hole and the first heat dissipation hole 201. In this way, the airflow entering the air guide structure 4 can be blown toward the components 21 in the housing 20 and discharged from the side of the components 21, so that the airflow and the components 21 are fully in contact, and the temperature of the components 21 is effectively reduced.

[0053] In a preferred embodiment of the present invention, Figure 1-4 The steam oven shown includes a box body 7, and the box body 7 is provided with a second heat dissipation hole 71 corresponding to the first heat dissipation hole 201. The second heat dissipation hole 71 and the first heat dissipation hole 201 form convection, so that the gas is discharged to the outside of the box body 7. The second heat dissipation hole 71 is opposite to the first heat dissipation hole 201, so that the airflow blown to the component 21 can be discharged from the first heat dissipation hole 201 and the second heat dissipation hole 71, so that part of the airflow blown by the fan 5 enters the second air guide channel 30, and the airflow directly acts on the component 21 that needs heat dissipation through the second air guide channel 30. At the same time, the first heat dissipation hole 201 and the second heat dissipation hole 71 form convection, which plays a role in heat dissipation for the component 21.

[0054] In a preferred embodiment of the present invention, Figure 1-4 The box body 7 is also provided with an exhaust hole 72 connected to the first air guide channel, so that the steam entering the first air guide channel is discharged to the outside of the box body 7. The exhaust hole 72 can be arranged as follows Figure 4 The front plate at the front end of the box body 7 shown, the first air outlet 301 on the air guide cover 3 and the exhaust hole 72 correspond to each other, so that the steam is discharged through the front end of the box body 7. Of course, the exhaust hole 72 can also be other positions of the box body 7, as long as it can correspond to the first air outlet 301 of the air guide cover 3, and this application does not limit it here.

[0055] In addition, an installation cavity can be formed between the box body 7 and the inner tank 1, and the air guide cover 3 and the fan 5 can be respectively arranged inside the installation cavity, and the box body 7 is provided with an air inlet 73 connected to the installation cavity. Of course, the air guide cover 3 and the fan 5 can also be outside the box body 7. When the air guide cover 3 and the fan 5 are both located in the cavity, when the steam oven is working, the gas in the cavity will become hot, and the fan 5 drives the gas in the cavity to enter the inside of the air guide cover 3. Since the air outlet is connected to the exhaust hole 72, the air flow inside the air guide cover 3 flows out of the box body 7 at a higher speed. At this time, the cavity is in a negative pressure state, and the gas outside the box body 7 will enter the cavity through the air inlet 73. The gas inside the cavity and the gas outside the box body 7 realize convection, which can take away the heat inside the cavity and achieve the effect of cooling the cavity.
