It has the advantages of saving space, good fume extraction effect, energy saving, low consumption and environmental protection.

[0003] The integrated stove comprises a stove body, in which a steam oven can be integrated to save kitchen space.

[0004] When users use the steam oven of the integrated stove to cook food, the heating tube in the steam oven box will generate a lot of heat. During the cooking process, the heat in the box is discharged into the public kitchen flue through the integrated stove heat dissipation duct. However, since the door of the steam oven is far away from the heat dissipation duct, the temperature of the glass panel outside the door is generally high, which can easily burn users and affect the user experience. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] Embodiment 1

[0044] See also Figure 1-Figure 6 The present embodiment provides a steam oven door, which can quickly dissipate heat when the steam oven is working, thereby avoiding burns to users due to the high temperature of the outer side of the steam oven door, thereby ensuring the user's usage experience.

[0045] Specifically, see Figure 1 and Figure 6 The steam oven door comprises a door body 1 and an air outlet member 2.

[0046] The door body 1 includes a perspective plate assembly 11 , and the perspective plate assembly 11 includes at least two partition chambers 12 . An air inlet is disposed at the lower end of each partition chamber 12 .

[0047] The air outlet member 2 is disposed at the upper end of the perspective plate assembly 11 , and is provided with a plurality of guide cavities 21 correspondingly connected to the upper ends of the partition cavities 12 . The hot air flow in the partition cavities 12 can be discharged through the corresponding guide cavities 21 .

[0048] Specifically, both ends of the flow guiding cavity 21 have an opening structure to facilitate air flow.

[0049] It should be noted that, in this embodiment, a number is at least two.

[0050] The steam oven door provided in this embodiment can be installed on the box body of the steam oven. When the steam oven is working, the steam oven door is in a closed state; the heating tube in the inner shell of the steam oven generates a large amount of heat. As the temperature in the box body increases, the temperature of the perspective plate assembly 11 of the door body 1 gradually increases, thereby causing the temperature of the air in the partition chamber 12 to gradually increase. An air inlet is provided at the lower end of the partition chamber 12, and a guide chamber 21 is provided at the upper end. The hot air in the partition chamber 12 continuously ascends and flows away from the guide chamber 21, and the low-temperature air from the outside continuously enters the partition chamber 12 from the air inlet at the lower end to reduce the temperature in the partition chamber 12, thereby forming a convection airflow in the partition chamber 12; the convection airflow continuously takes away the heat of the perspective plate assembly 11 to prevent the temperature of the perspective plate assembly 11 from being too high.

[0051] The vertical convection direct exhaust mode can quickly discharge the hot air in the partition cavity 12 in the perspective plate assembly 11, and continuously exchange heat to reduce the surface temperature of the perspective plate assembly 11.

[0052] At the same time, several guide chambers 21 are connected to several partition chambers 12 in a one-to-one manner, and the high-temperature air in each partition chamber 12 is smoothly discharged through its corresponding guide chamber 21, thereby preventing the high-temperature air discharged from the partition chamber 12 from forming turbulence in the air outlet piece 2 and affecting the heat dissipation effect of the door body 1.

[0053] It is understandable that the steam oven door provided in this embodiment is not limited to be used only in a steam oven. The steam oven door can also be used in a steamer, an oven or other cooking equipment.

[0054] Specifically, see Figure 4-Figure 6 In this embodiment, a cavity is provided in the air outlet member 2 and is directly opposite to the perspective plate assembly 11 . A partition 23 is provided in the cavity, and the partition 23 divides the cavity into a plurality of guide cavities 21 .

[0055] The partition 23 divides the cavity into a plurality of guide chambers 21 to prevent the high-temperature air discharged from the partition chamber 12 from forming turbulence in the air outlet member 2 and affecting the heat dissipation effect of the door body 1 .

[0056] Preferably, the partition 23 is a partition plate integrally formed and disposed in the cavity.

[0057] Furthermore, the air outlet member 2 includes a baffle 24, which is arranged at one end of the cavity away from the perspective plate assembly 11. The baffle 24 is provided with a baffle outlet group corresponding to the guide cavity 21, and the baffle outlet group includes a plurality of baffle outlets 241 arranged at intervals.

[0058] A baffle plate 24 is provided at one end of the cavity away from the perspective plate assembly 11 to prevent foreign matter from falling from the upper end of the cavity into the cavity when the steam oven door is in a closed state to affect the normal heat dissipation of the steam oven door. The baffle air outlet group is provided to ensure that the hot air in the guide cavity 21 can be discharged normally from the upper end of the steam oven door.

[0059] See also Figure 1 and Figure 2 The door body 1 also includes a door bracket 14 , the perspective plate assembly 11 is arranged on the door bracket 14 , and the air outlet member 2 is clamped on the door bracket 14 .

[0060] The air outlet member 2 is clamped to the door bracket 14 , so that the air outlet member 2 can be quickly disassembled and assembled on the door bracket 14 , making it convenient for users to clean and maintain the perspective plate assembly 11 .

[0061] Optionally, one of the air outlet member 2 and the door bracket 14 is provided with a buckle 22 , and the other is provided with a snap-fitting hole 141 that cooperates with the buckle 22 .

[0062] Specifically, in this embodiment, a buckle 22 is provided on the air outlet member 2 , and a clamping hole 141 cooperating with the buckle 22 is provided on the door body bracket 14 .

[0063] In order to further improve the heat dissipation effect of the door body 1, in this embodiment, a lateral air inlet group 144 is provided on the door body bracket 14, and the lateral air inlet group 144 is connected to at least one partition cavity 12. The lateral air inlet group 144 can supply low-temperature air to at least one partition cavity 12 from the side to improve the heat dissipation effect.

[0064] Preferably, in this embodiment, the lateral air inlet hole group 144 is connected to all the partition chambers 12 to fully ensure the heat dissipation effect of the door body 1.

[0065] Specifically, in this embodiment, the perspective panel assembly 11 includes a glass panel, and a low-emissivity layer 114 is formed on the glass panel by using a coating process.

[0066] The low-emissivity layer 114 reflects a large amount of far-infrared radiation heat in the inner cavity of the box that escapes to the environment back into the inner cavity of the box, thereby reducing the temperature rise rate of the perspective plate assembly 11.

[0067] The coating process includes the following steps:

[0068] S1, placing an evaporation source and an evaporation material in a vacuum environment, setting the temperature of the vacuum environment to a first set temperature, placing a glass plate in the vacuum environment, and under the action of the evaporation source and the evaporation material, depositing a low-emissivity layer 114 on one side of the glass plate;

[0069] The low-emissivity layer 114 is prepared in a vacuum environment, so that the thickness of the low-emissivity layer 114 is controllable; the low-emissivity layer 114 is not easily contaminated, so a low-emissivity layer 114 with good density, high purity and uniform coating can be obtained; at the same time, the low-emissivity layer 114 prepared in a vacuum environment has good bonding strength with the glass plate and is more solid;

[0070] Optionally, the vacuum degree of the vacuum environment is 10-1Pa to 10-6Pa;

[0071] Optionally, the first set temperature is 600°C-1100°C, preferably 800°C-1100°C; specifically, the evaporation source is a chemical solution with tin salt as the main component; under the action of the evaporation source, the evaporation material moves linearly in any direction in an atomic or molecular state, and when it encounters the surface of the glass plate with a lower temperature, it is adsorbed. Due to the continuous increase of particles, a film layer is gradually formed on the surface of the glass plate, and finally a low-emissivity layer 114 is formed;

[0072] S2, placing the glass plate under a second set temperature environment for annealing.

[0073] Optionally, the second set temperature is 25°C-600°C.

[0074] Specifically, in step S1, a CVD coating device is used to coat the glass plate. From the evaporation of the evaporation material to the formation of a film on the surface of the glass plate, it can be divided into four stages:

[0075] (1) Initial stage: When the incident evaporation material particles are adsorbed by the cold glass plate, a large number of crystal nuclei appear in the initial stage of forming a film layer on the glass plate. The diameter of the crystal nucleus is about 2nm, and the distance between adjacent crystal nuclei is about 30nm. More and more atoms are adsorbed, forming small islands of different shapes on the surface of the glass plate. The process of atoms combining with each other in an instant is as follows: two atoms that exist separately, more and more atoms are adsorbed, the contact area gradually becomes larger, and the atoms are connected to form small islands.

[0076] (2) Agglomeration stage: As the vapor of the evaporating material is continuously generated, the original small islands are expanded and connected to form large islands. The atoms adsorbed on the surface of the glass plate have condensed into small islands, and the vapor atoms that arrive later continuously fill the gaps between the small islands and aggregate into large islands.

[0077] (3) Intermediate process: The edges of the large islands are irregularly connected to form a mesh film, channel, passage, and hole stage. The amount of vapor of the evaporating material gradually increases, and a honeycomb structure is formed between the large islands. The gaps begin to connect, but the connected parts are not dense enough.

[0078] (4) Film formation stage: Based on the channel stage, as the vapor atoms of the evaporated material are continuously adsorbed and continuously filled around the channel, a low-emissivity layer 114 is gradually formed. The thickness of the low-emissivity layer 114 is not uniform at the microscopic level, but is uneven.

[0079] Compared with the prior art in which a chemical solution with tin salt as the main component is directly sprayed on the surface of the glass plate to form a single layer of tin oxide (SnO2) compound film with certain low-radiation function, in this embodiment, the low-radiation layer 114 formed by the action of evaporation material and evaporation source in a vacuum environment is denser and more stable.

[0080] Specifically, in step S2, the glass sheet undergoes drastic temperature changes and shape changes during the forming process of the low-emissivity layer 114, and such changes leave thermal stress in the glass sheet. Such thermal stress will reduce the strength and thermal stability of the glass sheet. If the glass sheet is cooled directly, it is very likely that the glass sheet will break by itself during the cooling process or during subsequent storage, transportation and use (commonly known as cold explosion of glass). In order to avoid the occurrence of cold explosion, the glass sheet must be annealed after the low-emissivity layer 114 is formed. Annealing is to keep warm or slowly cool down for a period of time within a certain temperature range to clean or reduce the thermal stress in the glass until the thermal stress reaches an allowable value. Optionally, the annealing temperature is between 25°C and 600°C.

[0081] Specifically, before step S1, the coating process further includes the following steps:

[0082] S0. Make glass plates.

[0083] Specifically, the process of making the glass sheet includes the following steps:

[0084] Ingredients: According to the designed material list, weigh various raw materials and mix them evenly in a mixer. The main raw materials of glass are: quartz sand, limestone, feldspar, soda ash, boric acid, etc.

[0085] Melting: heating the prepared raw materials at the third set temperature to form a uniform glass liquid without bubbles; specifically, the third set temperature is 1100-1600°C;

[0086] Molding: The melted glass liquid is transformed into a solid product with a fixed shape; the molding temperature is between 1100 and 1600°C, and the molding process is a cooling process. The glass first changes from a viscous liquid to a plastic state, and then to a brittle solid state.

[0087] Specifically, the forming process adopts mechanical forming; such as mechanical forming pressing, blowing or drawing.

[0088] Specifically, in this embodiment, the light transmittance of the finally formed glass plate is 75%-79%; the emissivity is less than 0.18; and the square resistance is less than 15Ω / m.

[0089] Specifically, see 2 and Figure 6 In this embodiment, the perspective plate assembly 11 includes a first inner glass plate 111, a second inner glass plate 112 and an outer glass plate 113 which are sequentially arranged at intervals.

[0090] A partition cavity 12 is disposed between the first inner glass plate 111 and the second inner glass plate 112 , and a partition cavity 12 is disposed between the second inner glass plate 112 and the outer glass plate 113 .

[0091] Furthermore, the air outlet piece 2 is also provided with a first inner glass plate clamping groove 25 which is clamped with the upper end of the first inner glass plate 111. When the air outlet piece 2 is clamped to the door body bracket 14, the upper end of the first inner glass plate 111 is clamped in the first inner glass plate clamping groove 25, further ensuring the stable installation of the air outlet piece 2.

[0092] A low-emissivity layer 114 is disposed on a surface of the first inner glass plate 111 facing away from the second inner glass plate 112 and a surface of the second inner glass plate 112 facing away from the outer glass plate 113 .

[0093] Preferably, the emissivity En of the low-emissivity layer 114 is less than 0.18.

[0094] Under the same cooking temperature conditions, the surface of the first inner glass plate 111 facing away from the second inner glass plate 112 and the surface of the second inner glass plate 112 facing away from the outer glass plate 113 are both provided with a low-emissivity layer 114. Compared with only the surface of the first inner glass plate 111 facing away from the second inner glass plate 112 being provided with a low-emissivity layer 114, the temperature of the outer surface of the steam oven door can be reduced by more than 5°C.

[0095] During the operation of the steam oven, the first inner glass plate 111 faces the inner cavity of the steam oven, and is subjected to the most heat radiation and heats up the fastest. A low-emissivity layer 114 is provided on the surface of the first inner glass plate 111 facing away from the second inner glass plate 112, that is, the surface of the first inner glass plate 111 facing the inner cavity of the steam oven. The low-emissivity layer 114 reflects a large amount of far-infrared radiation heat in the inner cavity of the box that escapes to the environment back into the inner cavity of the box, thereby reducing the heating rate of the first inner glass plate 111.

[0096] The second inner glass plate 112 is sandwiched between the first inner glass plate 111 and the outer glass plate 113. Compared with the outer glass plate 113, the second inner glass plate 112 heats up faster. A low-emissivity layer 114 is provided on the surface of the second inner glass plate 112 facing away from the outer glass plate 113, that is, the surface of the second inner glass plate 112 facing the first inner glass plate 111. The low-emissivity layer 114 reflects a large amount of far-infrared radiation heat in the inner cavity of the box body that escapes to the environment back into the inner cavity of the box body, thereby reducing the rapid heating of the second inner glass plate 112.

[0097] Specifically, in this embodiment, the door body bracket 14 includes two hollow columns 143 that are relatively arranged, and a through cavity with openings at both ends is arranged in the hollow column 143, and the two hollow columns 143 are fixedly connected to the inner surface of the outer glass plate 113; a connecting block 115 is respectively arranged at both ends of the outer surface of the first inner glass plate 111, and each connecting block 115 is provided with a snap-in groove 1151, and the second inner glass plate 112 is installed in the two snap-in grooves 1151, so as to be arranged relative to the first inner glass plate 111; the connecting block 115 is also fixedly connected to the inner surface of the outer glass plate 113, so as to realize the overall assembly of the door body 1, and at the same time realize the relative spacing between the second inner glass plate 112 and the outer glass plate 113.

[0098] Specifically, a support corner 142 is sleeved inside the lower end of the hollow column 143 to provide better support for the door body bracket 14 .

[0099] The upper end of the outer side surface of each hollow column 143 is provided with a snap-fitting hole 141, and the air outlet member 2 is provided with two snap-fitting buckles 22, which are snap-fitted with the snap-fitting holes 141 in a one-to-one correspondence. In this way, the steam oven door is assembled.

[0100] Specifically, the buckle 22 includes an elastic arm and a latching protrusion arranged on the side of the lower end of the elastic arm. When the air outlet piece 2 is connected to the door body bracket 14, the elastic arm extends into the inner cavity of the corresponding hollow column 143, and the latching protrusion is latched in the latching hole 141 to prevent the latching hole 141 from detaching from the door body bracket 14 during use of the steam oven door.

[0101] In order to achieve the connection between the lateral air inlet hole group 144 and all the partition chambers 12, the lateral air inlet hole group 144 includes an outer side inlet hole group 1441 and two inner side inlet hole groups 1442; the outer side inlet hole group 1441 is arranged on the outer side of the hollow column 143, and the inner side inlet hole group 1442 is arranged on the inner side of the hollow column 143. The outer side inlet hole group 1441 includes a row of outer side inlet holes arranged at intervals along the extension direction of the hollow column 143; the inner side inlet hole group 1442 includes a row of inner side inlet holes arranged at intervals along the extension direction of the hollow column 143. The two inner side inlet hole groups 1442 are connected to the two partition chambers 12 in a one-to-one correspondence. The low-temperature air from the outside enters the hollow column 143 through the outer side inlet hole group 1441, and the low-temperature air in the hollow column 143 enters the two partition chambers 12 respectively through the two inner side inlet hole groups 1442, thereby accelerating the cooling rate in the partition chamber 12.

[0102] Specifically, the thickness of the two partition chambers 12 can be the same or different, as required. Preferably, the thickness of the partition chamber 12 between the first inner glass plate 111 and the second inner glass plate 112 is greater than the thickness of the partition chamber 12 between the second inner glass plate 112 and the outer glass plate 113.

[0103] Exemplarily, in this embodiment, the air flow path in the steam oven door is as follows:

[0104] The external low-temperature air enters the partition chamber 12 through the air inlet at the lower end of the partition chamber 12 and the lateral air inlet hole group 144. The air in the partition chamber 12 is radiantly heated by the heating tube in the inner shell of the steam oven. After being heated, the air in each partition chamber 12 flows upward and flows into the corresponding guide chamber 21, and finally flows out from the baffle air outlet 241. The external low-temperature air that continuously enters is heated and flows away, taking away the temperature of the door body 1, so as to avoid the steam oven door temperature being too high after the steam oven is finished working and burning the user.

[0105] Low-temperature air can enter the lower end and two sides of the steam oven door, forming a three-sided cold air flow channel structure to accelerate heat dissipation.

[0106] Embodiment 2

[0107] This embodiment provides a steam oven.

[0108] Specifically, the steam oven comprises a box body, and the steam oven door of the first embodiment is hingedly provided at the opening of the box body.

[0109] Specifically, the door of the steam oven is hinged to the lower end of the opening of the box body. The specific implementation method of the hinge is the existing technology and will not be introduced in detail here.

[0110] During the operation of the steam oven, the door of the steam oven is in a closed state. The heating tube in the inner shell of the steam oven generates a large amount of heat. As the temperature in the box increases, the temperature of the perspective plate assembly 11 of the door body 1 gradually increases, thereby gradually increasing the temperature of the air in the partition chamber 12. An air inlet is provided at the lower end of the partition chamber 12, and a guide chamber 21 is provided at the upper end. The hot air in the partition chamber 12 continuously ascends and flows away from the guide chamber 21, and the low-temperature air from the outside continuously enters the partition chamber 12 from the air inlet at the lower end to reduce the temperature in the partition chamber 12, thereby forming a convection airflow in the partition chamber 12; the convection airflow continuously takes away the heat of the perspective plate assembly 11 to prevent the temperature of the perspective plate assembly 11 from being too high.

[0111] At the same time, several guide chambers 21 are connected to several partition chambers 12 in a one-to-one manner, and the high-temperature air in each partition chamber 12 is smoothly discharged through its corresponding guide chamber 21, thereby preventing the high-temperature air discharged from the partition chamber 12 from forming turbulence in the air outlet piece 2 and affecting the heat dissipation effect of the door body 1.

[0112] Furthermore, in this embodiment, the steam oven also includes a smoke removal and odor purification device, which is arranged in the external space position of the pressure relief port on the top of the inner shell of the steam oven. The smoke removal and odor purification device is mainly composed of oil-blocking filter, heating tube, catalytic assembly, smoke removal catalytic cover, exhaust pipe assembly, fan blades, fan cover, active suction fan, two-way exhaust channel assembly pipe and other sub-components.

[0113] When using a steam oven to cook foods with high fat content, a large amount of oil smoke will be produced. The liquid oil droplets in the oil smoke are first filtered through the oil-blocking filter of the smoke removal and odor purification device, and the gaseous oil smoke is heated by the heating tube at a temperature range of 400℃-700℃. In this high-temperature environment, the catalytic component will cause the oil smoke to chemically react and catalytically decompose it into carbon dioxide and water, which are then discharged through the exhaust pipe assembly.

[0114] Furthermore, the catalytic component is a metal disc structure woven from metal wires, which effectively increases the effective contact area. In order to improve the catalytic decomposition effect of oil smoke, an oil smoke catalytic material (a precious metal material that can catalytically decompose oil smoke at 400-700°C) is coated on the surface of the catalytic component. Under high temperature, the catalytic material catalyzes the oil smoke into carbon dioxide and water. Under high temperature, the water becomes water vapor and is discharged along with the gas.

[0115] Furthermore, the exhaust pipe assembly is designed as a two-way exhaust channel mode, which is divided into an external exhaust channel mode and an internal exhaust channel mode.

[0116] The external exhaust channel method is that when the oven cooks foods with less fat, a small amount of oil smoke will be produced. The active suction fan is not started. This part of the oil smoke will naturally pass through the oil-blocking filter to filter the oil droplets. The heating tube is heated to 400℃-700°C. The oil smoke is decomposed into carbon dioxide and water by the catalytic component at high temperature, and then passes through the exhaust pipe, the exhaust channel air inlet, the two-way exhaust channel component pipe and the external exhaust channel outlet at one time, enters the heat dissipation duct, and is discharged from the oven box under the action of the heat dissipation fan.

[0117] The inner exhaust channel method is that when the oven cooks foods with high fat content, a large amount of oil smoke will be generated. The active suction fan starts to actively absorb the oil smoke, and the oil smoke is filtered through the oil-blocking filter. The heating tube is heated to 400°C-700°C, and the oil smoke is decomposed into carbon dioxide and water through the high temperature of the catalytic component. Then, it passes through the exhaust pipe, the exhaust channel air inlet, the two-way exhaust channel component pipe, and the inner exhaust channel outlet in sequence, and enters the baking inner cavity of the oven, forming an inner exhaust channel method.

[0118] The internal exhaust channel method can effectively reduce the heat consumption of the smoke removal and odor purification device during the baking process of the steam oven, reduce the impact on the internal temperature field of the steam oven, and is beneficial to ensure the baking and cooking effect.
