Description

Technical Field

[0001] The utility model relates to the field of kitchen appliances, in particular to a steam frying and roasting machine. Background Art

[0002] When using an ordinary grilling machine, as the food is heated at high temperature, the water content in the food evaporates during the cooking process, which can easily make the food dry and the taste worse. In order to solve this problem, a steam grilling machine is launched on the market, that is, a water storage tank is provided on the grilling machine. By adding water to the water storage tank, during use, as the lower baking tray is heated, the heat can be used to evaporate the water in the water storage tank to generate steam, which can replenish moisture for the food and improve the taste of the food.

[0003] In the prior art, in the scheme with a water storage structure, the water storage tank occupies a large space. For example, in the grilling machine disclosed in Chinese patent CN115137226A, multiple water storage tanks are provided with a large volume protruding outward relative to the working area of ​​the lower grilling plate, resulting in an increase in the overall volume of the lower grilling plate, which increases the manufacturing cost. Furthermore, the grilling machine is formed with a water supply tank and a water injection port. When water is injected, water enters the water storage tank through the water supply tank, and the water injection efficiency is low; and the water injection port is basically vertically arranged. When water is injected from the water injection port, the water has to flow down along the side plate for a long distance before flowing into the water supply tank, which greatly limits the water injection efficiency. In addition, due to the large water drop difference, some water droplets may splash onto the working area during water injection. The user needs to wipe the water in the working area before refueling, or when the user does not notice this part of the water and directly refuels, the water mixed in the edible oil is easily splashed outward after being heated, which may scald the user, thus posing a safety hazard and reducing the reliability of the machine. Utility Model Content

[0004] In order to solve the technical problems in the prior art that the water storage tank is arranged outside the radial area of ​​the baking tray, resulting in an excessively large radial volume of the baking tray, and the above-mentioned low efficiency of adding water to the water storage tank through the water injection port, and that part of the water is easily splashed into the working area when adding water, affecting the safety of use or increasing the workload of the user, the utility model provides a steam grilling machine, which forms a water storage portion inside the lower baking tray to avoid the water storage portion being convex to increase the radial volume of the lower baking tray, and at the same time adopts an inclined water injection nozzle to buffer the water flow, and adopts a water guide surface for drainage, which can reduce the probability of water splashing into the cooking area during the water injection process, thereby improving the reliability and safety of use.

[0012] The first side wall is extended upwardly along the bottom wall, and the water storage portion is arranged at the same height as the cooking area.

[0013] The first side wall is extended downwardly along the bottom wall, and the water storage portion is sunken relative to the cooking area.

[0014] The heating tube is arranged on the outer surface of the lower baking tray, the water storage portion surrounds the outer side of the heating tube, the heating tube includes an annular first heating section, and the radial distance between the first heating section and the water storage portion is smaller than the radial distance between the first heating section and the center of the lower baking tray.

[0015] A heat-conducting rib is provided on the outer surface of the lower baking pan, and the heat-conducting rib extends from the first heating section to the water storage portion.

[0018] In addition, a water guide surface is formed inside the water injection nozzle, which is conducive to guiding water to flow smoothly into the water storage part, which can reduce the probability of water splashing into the cooking area; and the first side wall can also block water to a certain extent, which can further reduce the probability of water splashing into the cooking area. The use of an annular water storage part can form a steam belt along the circumference of the lower baking tray, which is conducive to replenishing water to various areas of the food, improving the uniformity of water replenishment, and thus improving the overall cooking effect and taste of the food.

[0019] 2. In order to simplify the structural design and reduce the cost of modifying the existing lower grill pan, as a preferred embodiment, the water guide surface is formed by folding the lower end of the second side wall outward, and the water guide surface is a concave arc surface, and the water guide surface is connected to the second side wall through a rounded transition.

In order to prevent the water from splashing when it falls into the water storage part when the water drop difference is large, causing the cooking area to be wet, as a preferred embodiment, a height difference is formed between the bottom end of the water guide surface and the water storage part, and the height difference is not greater than 5mm. That is, by reducing the height difference, water can avoid splashing when it falls into the water storage part through the bottom end of the water guide surface.

[0022] 5. In order to speed up the filling of the water storage part with water, as a preferred embodiment, the bottom wall of the water storage part is inclined from the outside to the inside, and an angle α is formed between the bottom wall of the water storage part and the horizontal plane, 0°<α<2°. That is, by setting the terrain difference of high outside and low inside, it is convenient for water to flow forward quickly to fill the water storage part, thereby improving the water filling efficiency.

[0023] 6.

That is, in addition to being used for adding water, the water injection nozzle can also serve as a liquid receiving groove to receive the oil or condensed water flowing down from the upper grilling pan, so that the oil receiving groove can be omitted, and the additional outwardly protruding oil receiving groove is avoided to increase the radial volume of the lower grilling pan, making the machine more compact and lightweight as a whole.

[0024] In addition, the water injection nozzle is connected to the atmosphere, and can also exhaust steam during the use of the machine, further expanding the use of the water injection nozzle. The water injection nozzle is located at the hinge, usually at the back of the machine, so that the exhaust steam can avoid blowing to the user, which can avoid interfering with the user's vision or scalding the user.

[0025] 7. In order to facilitate the formation of the water storage part, as a preferred embodiment, the first side wall is extended upwardly along the bottom wall, and the water storage part is arranged at the same height as the cooking area. In this embodiment, the water storage part and the cooking area are arranged at the same height, which is convenient for processing, and the first side wall separates the cooking area and the water storage part, which can play a role of blocking water and prevent the water in the water storage part from flowing into the cooking area.

[0026] 8. In order to prevent the water in the water storage part from flowing to the cooking area and affecting the contact between the cooking oil and the food, and to reduce the amount of steam, as a preferred embodiment, the first side wall is extended downward along the bottom wall, and the water storage part is sunken relative to the cooking area. In this embodiment, the water storage part is arranged lower than the cooking area, so that water is prevented from flowing to the cooking area.

[0027] 9. In order to increase the evaporation rate of water in the water storage part so that steam can replenish water to the food in time, as a preferred embodiment, the heating pipe is arranged on the outer surface of the lower grill, the water storage part surrounds the outer side of the heating pipe, and the heating pipe includes a first annular heating section, and the radial distance between the first heating section and the water storage part is smaller than the radial distance between the first heating section and the center of the lower grill. The first heating section is mainly used to heat the area close to the outer ring of the lower grill, and its arrangement close to the water storage part is conducive to increasing the evaporation rate of water in the water storage part so that steam can replenish water to the food in time and make the food soft.

[0028] Furthermore, in one embodiment, a heat conducting rib is provided on the outer surface of the lower baking tray, and the heat conducting rib extends from the first heating section to the water storage portion. By providing the heat conducting rib to enhance heat transfer, the heat of the first heating section can be accelerated to reach the water storage portion, so as to further increase the evaporation rate of water.

[0045] like Figures 1 to 6 As shown, the present application provides a steam grilling machine, comprising a lower grilling plate assembly 10, wherein the lower grilling plate assembly 10 comprises a lower grilling plate 12 and a heating pipe for heating the lower grilling plate 12, wherein the lower grilling plate 12 comprises a bottom wall 121, a first side wall 122 arranged around the bottom wall 121, and a second side wall 123 arranged around the outside of the first side wall 122, wherein an annular water storage portion 13 is enclosed between the first side wall 122 and the second side wall 123, wherein the bottom wall 121 is located at the inner side of the water storage portion 13 to form a cooking area 124, wherein a portion of the second side wall 123 protrudes outward to form a water injection nozzle 14 inclined toward the water storage portion 13 and connected to the water storage portion 13, and the inner side of the water injection nozzle 14 is recessed to form a water guide surface 141 for guiding water to the water storage portion 13.

[0046] In order to solve the technical problems that the protruding water storage structure leads to an increase in the overall radial volume of the grilling pan and low water injection efficiency, the steam grilling machine of the utility model forms a water storage part 13 inside the lower grilling pan 12, which can maintain the original radial size of the lower grilling pan 12 without occupying additional space, greatly saving space and materials, making the machine look light and compact as a whole, not only saving costs but also improving aesthetics. When water is added from the water injection nozzle 14 to the water storage part 13, a certain water flow buffer can be provided while ensuring the water addition efficiency, which can prevent water from impacting the water storage part 13 and causing splashes in the cooking area 124, causing the cooking area 124 to get wet, thereby increasing the workload of the user or causing oil and water mixing and heating to splash and injure the user, thereby improving the safety of use.

[0047] In addition, a water guide surface 141 is formed inside the water injection nozzle 14, which is conducive to guiding water to flow smoothly into the water storage portion 13, and can reduce the probability of water splashing into the cooking area 124; and the first side wall 122 can also block water to a certain extent, which can further reduce the probability of water splashing into the cooking area 124. The annular water storage portion 13 can form a steam belt along the circumference of the lower baking tray 12, which is conducive to replenishing water to various areas of the food, improving the uniformity of water replenishment, and thus improving the overall cooking effect and taste of the food.

[0048] Specifically, during the use of the grilling machine of the present application, water is added to the water storage part 13. During the heating of the grill pan, the water in the water storage part 13 evaporates and vaporizes, and steam can be provided to the food at 360 degrees, making the food soft inside and crispy outside, thereby improving the taste of the food. Furthermore, during the heating of the food, the steam in the cooking cavity can be exhausted through the water injection nozzle 14, thereby expanding the function of the water injection nozzle 14. The water storage part 13 has a certain width, for example, a width range of 8-15 mm, for easy cleaning.

[0049] In order to simplify the structural design and reduce the modification cost of the existing lower grill pan 12, as a preferred embodiment, the water guide surface 141 is formed by folding the lower end of the second side wall 123 outward, and the water guide surface 141 is a concave arc surface, and the water guide surface 141 is connected to the second side wall 123 through a rounded transition. Figure 2 As shown, in this embodiment, the water injection nozzle 14 has a simple structure and is conducive to reducing the volume of the water injection nozzle 14 itself, thereby helping to reduce the overall radial volume of the lower grill plate 12; the water guide surface 141 adopts a concave arc surface, and when water is injected, the water is buffered by the concave arc surface and then flows into the water storage portion 13, which can reduce the probability of water splashing into the cooking area 124, and the concave arc surface can temporarily store a certain amount of water, so that the water can continuously and smoothly flow from the concave arc surface through a smooth transition into the water storage portion 13, so as to improve the water adding efficiency and the reliability of the water adding operation.

[0050] like Figure 2 and Figure 3 As shown, the second side wall 123 extends vertically, for example, and only protrudes outward at the water injection nozzle 14, and the water guide surface 141 has a certain width to facilitate water injection.

[0051] In order to prevent water overflow during the water injection process, reduce water waste and ensure water injection efficiency, as a preferred embodiment, the water injection nozzle 14 is a water injection channel 142 extending outwardly along the second side wall 123, and the inner wall of the water injection channel 142 forms the water guide surface 141. Figure 4As shown, in this embodiment, water overflow can be effectively prevented when adding water through the water injection channel 142, and the channel is conducive to water gathering. When a certain amount of water is maintained in the channel, water can be discharged continuously and smoothly to the water storage part 13, which is convenient for controlling the water addition flow rate; further, the inner wall of the water injection channel 142 increases the area of ​​the water guide surface 141, which can optimize the water guide effect, and by restricting the path of the water flow, it can avoid water splashing randomly and causing water splashes.

[0052] Although Figure 4 The U-shaped water injection channel 142 is shown, but it does not constitute a limitation of the present application, and the circumferentially surrounded channel structure is also within the protection scope of the present application. When the amount of water in the water injection channel 142 is small, the inner bottom wall and the inner side wall of the water injection channel 142 form a water guide surface 141, and when the amount of water in the water injection channel 142 is large, the inner top wall of the water injection channel 142 will also contact with water to form a water guide surface 141 together. The length of the water injection channel 142 extending outward should not be too large, so as not to increase the volume of the lower baking tray 12.

[0053] In order to prevent the water from splashing when the water falls into the water storage part 13 when the water drop difference is large, causing the cooking area 124 to be wet, as a preferred embodiment, a height difference h is formed between the bottom end of the water guide surface 141 and the water storage part 13, and the height difference h is not greater than 5mm. Figure 3 As shown, by reducing the height difference h, water can avoid splashing when it falls into the water storage portion 13 through the bottom end of the water guide surface 141. More specifically, the height difference h is greater than zero.

[0054] It is understandable that in other embodiments, the bottom end of the water guide surface 141 may also extend to be flush with the bottom of the water storage portion 13, which is conducive to the water flowing smoothly into the water storage portion 13 along the inclined water guide surface 141, thereby reducing the impact of the water flow on the water storage portion 13 and reducing the probability of water splashing into the cooking area 124.

[0055] In order to speed up the filling of the water storage part 13 with water, as a preferred embodiment, the bottom wall of the water storage part 13 is inclined from the outside to the inside, and an angle α is formed between the bottom wall of the water storage part 13 and the horizontal plane, 0°<α<2°. That is, by setting the terrain difference of high outside and low inside, it is convenient for water to flow forward quickly to fill the water storage part 13, thereby improving the water filling efficiency.

[0056] It should be noted that, for the annular water storage portion 13, the angle α can be set in the entire circle of the water storage portion 13, or only in the semicircle corresponding to the water injection nozzle 14, while the bottom wall of the other semicircular water storage portion 13 is set horizontally.

[0057] In order to further reduce the volume of the lower grilling tray 12 and increase the versatility of the water injection nozzle 14, as a preferred embodiment, the steam grilling machine also includes an upper grilling tray assembly 11, and the upper grilling tray assembly 11 is hingedly connected to the lower grilling tray assembly 10, and the lower grilling tray assembly 10 is provided with a hinged seat, and the water injection nozzle 14 is arranged opposite to the inner side of the hinged seat, and when the upper grilling tray assembly 11 is in a flip-cover state, the water injection nozzle 14 is used to receive oil or condensed water from the upper grilling tray assembly 11.

[0058] That is, in addition to being used for adding water, the water injection nozzle 14 can also serve as a liquid receiving groove to receive the oil or condensed water flowing down from the upper baking tray, so that the oil receiving groove can be omitted, and the radial volume of the lower baking tray 12 can be increased by additionally setting an oil receiving groove protruding outward, so as to make the machine more compact and light as a whole. Specifically, the upper baking tray assembly 11 includes an upper baking tray, and a guide groove is provided at a position corresponding to the upper baking tray and the water injection nozzle 14. During use, when the user opens the upper baking tray assembly 11, condensed water is easily formed on the upper baking tray at this time, and the condensed water flows along the upper baking tray into the guide groove, and then flows into the water injection nozzle 14, which can avoid the condensed water flowing onto the desktop and increasing the workload of the user. This part of the condensed water can also be used for evaporation to generate steam to replenish food in the subsequent processing process, providing a recycling method. Alternatively, when the upper baking tray is coated with edible oil, when the upper baking tray assembly 11 is opened, the oil can also flow into the water injection nozzle 14 through the guide groove, and the special oil receiving groove can be omitted. It is understandable that the functions of adding oil to the upper baking tray and water to the water storage portion 13 can be used separately to prevent the oil from entering the water storage portion 13 through the water injection nozzle 14, causing water and oil to mix and cause flavor contamination.

[0059] In addition, the water injection nozzle 14 is connected to the atmosphere, and can also exhaust steam during the use of the machine, further expanding the use of the water injection nozzle 14. The water injection nozzle 14 is arranged at the hinge, usually at the rear side of the machine, so that the steam can be exhausted without blowing to the user, which can avoid interfering with the user's vision or scalding the user.

[0060] In order to facilitate the formation of the water storage portion 13, as a preferred embodiment, the first side wall 122 is extended upwardly along the bottom wall 121, and the water storage portion 13 is arranged at the same height as the cooking area 124. Figure 5 As shown, in this embodiment, the water storage portion 13 and the cooking area 124 are arranged at the same height for easy processing, and the first side wall 122 separates the cooking area 124 and the water storage portion 13, which can play a role in blocking water and preventing water in the water storage portion 13 from flowing into the cooking area 124.

[0061] In order to prevent the water in the water storage part 13 from flowing into the cooking area 124 to affect the contact between the cooking oil and the food, and to reduce the amount of steam, as a preferred embodiment, the first side wall 122 is extended downward along the bottom wall 121, and the water storage part 13 is sunken relative to the cooking area 124. Figure 6 As shown, in this embodiment, the water storage portion 13 is arranged lower than the cooking area 124 , thereby preventing water from flowing into the cooking area 124 .

[0062] In order to increase the evaporation rate of water in the water storage part 13 so that steam can replenish water to the food in time, as a preferred embodiment, the heating pipe is arranged on the outer surface of the lower grill 12, the water storage part 13 surrounds the outer side of the heating pipe, and the heating pipe includes an annular first heating section, and the radial distance between the first heating section and the water storage part 13 is smaller than the radial distance between the first heating section and the center of the lower grill 12. Among them, the first heating section is mainly used to heat the area close to the outer circle of the lower grill 12, and its arrangement close to the water storage part 13 is conducive to increasing the evaporation rate of water in the water storage part 13, so that steam can replenish water to the food in time and make the food soft.

[0063] In order to increase the heating area of ​​the lower grill 12 and improve the uniformity of food heating, the heating tube also includes a second heating section arranged inside the first heating section, and the second heating section can heat the area of ​​the lower grill 12 close to the inner circle.

[0064] Furthermore, in one embodiment, heat conducting ribs are provided on the outer surface of the lower baking tray 12, and the heat conducting ribs extend from the first heating section to the water storage portion 13. By providing heat conducting ribs to enhance heat transfer, the heat of the first heating section can be accelerated to reach the position of the water storage portion 13, so as to further increase the evaporation rate of water.

[0065] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model.
