Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, specifically a household sweet potato baking oven. Background Art

[0002] Baked sweet potatoes are common snacks in daily life and are very popular among the general public because of their sweet taste. However, currently, to get baked sweet potatoes, one can only buy them at special stalls, which cannot meet people's needs.

[0003] To solve the above problems, a series of household sweet potato ovens have emerged in the prior art, meeting people's need to make and eat baked sweet potatoes at home. During the process of baking sweet potatoes, the surface temperature is high and the water evaporates quickly. Usually, when baking other foods, we will appropriately add water to avoid excessive evaporation of water and burning. However, since sweet potatoes are baked whole, it is not convenient to add water, and if the baking time is too long, it is easy to get burned. The sweet potato ovens in the prior art cannot solve this problem. Summary of the Invention

[0004] The present invention aims to provide a household sweet potato baking oven to solve the problem that sweet potatoes are easily burned due to excessive evaporation of surface water in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solution:

[0006] A household sweet potato baking oven includes a box body. An electric hot plate is arranged inside the side wall of the box body. A baking tray is arranged inside the box body. A water storage cavity is arranged inside the baking tray. A water filling port is arranged on the baking tray. A plurality of steam escape holes are arranged on the top of the baking tray, and the steam escape holes are communicated with the water storage cavity.

[0007] The principle and beneficial effects of this solution are as follows:

[0008] The electric hot plate is used for heating to bake sweet potatoes, and the baking tray is used for placing sweet potatoes. A water storage cavity is arranged inside the baking tray to hold water. During the baking process, the water is heated to form steam, which floats out from the steam escape holes onto the sweet potatoes. Thus, it can supplement water to the surface of the sweet potatoes, avoiding the sweet potatoes from being burned due to too fast evaporation of surface water. In addition, after baking, the remaining hot water in the baking tray can keep the sweet potatoes that are not eaten in time warm.

[0009] Further, the baking tray includes a rectangular ring-shaped grill and a plurality of support pipes. The water storage cavity is arranged inside the grill. The support pipes are communicated with the water storage cavity. The support pipes are connected to the inner wall of the grill, and the steam escape holes are arranged on the support pipes. Using the support pipes and the grill to form the baking tray, without affecting the escape of steam, it can reduce the contact area between the sweet potatoes and the baking tray, thereby increasing the area for receiving heat, making the heating condition better and the baking more uniform.

[0010] Furthermore, an adjusting mechanism for regulating the steam output is provided inside the support pipe. The adjusting mechanism is used to regulate the amount of steam wafting into the support pipe to meet the steam demand when baking different quantities of sweet potatoes.

[0011] Furthermore, the adjusting mechanism includes a flexible pipe core disposed inside the support pipe. The diameter of the pipe core gradually decreases from one end to the other end. The large-diameter end of the pipe core is fixedly connected inside the support pipe, and the small-diameter end of the pipe core extends into the water storage cavity. An air outlet channel is formed between the pipe core and the support pipe. The support pipe is connected to the grill through an elastic pipe, and the support pipe is connected to the upper part of the grill. The more the number of sweet potatoes, the more steam is required. By connecting the support pipe with an elastic pipe, the weight of the sweet potatoes can be used to press down the support pipe, thereby pulling the pipe core from outside the water storage cavity. As a result, the small-diameter end of the pipe core moves to the connection between the support pipe and the grill, thus increasing the area of the air outlet channel and further increasing the amount of steam escaping.

[0012] Furthermore, the elastic pipe includes a corrugated pipe with a sandwich layer, and a spring is disposed along the length direction inside the sandwich layer of the corrugated pipe. The corrugated pipe is used to provide space for the support pipe to be pressed down, and the spring is used to drive the support pipe to reset.

[0013] Furthermore, the steam escape holes are provided on the side surface of the support pipe. Such a setting can prevent the steam escape holes from being blocked by sweet potatoes, thus affecting the steam dispersion.

[0014] Furthermore, the baking tray is horizontally slidably connected inside the box body. Such a setting facilitates pulling out the baking tray to place and take out sweet potatoes.

[0015] Furthermore, sliding grooves are provided on the side walls of the oven, and sliding blocks are provided on the baking tray. The sliding blocks are slidably connected inside the sliding grooves. The sliding of the baking tray is realized by the sliding of the sliding blocks inside the sliding grooves, with a simple structure and good sliding stability.

[0016] Furthermore, an electric heating plate is also provided inside the top wall of the box body. Such a setting can enable the top of the sweet potatoes to also receive heat, further increasing the uniformity of sweet potato baking.

[0017] Furthermore, a handle is provided on the baking tray. The handle is used for the user to hold to pull out the baking tray, which is convenient for operation. Description of the Drawings

[0018] Figure 1 is a schematic structural diagram of Embodiment 1 of the present invention;

[0019] Figure 2 is a longitudinal sectional view of the connection between the support pipe and the grill. Detailed Embodiments

[0020] The following is a further detailed description through specific embodiments:

[0021] The reference numerals in the accompanying drawings of the specification include: grill 1, support tube 2, steam escape hole 3, elastic tube 4, box body 5, spring 6, steam outlet channel 7, steam outlet hole 8, tube core 9, water storage cavity 10, baking tray 11, corrugated tube 12.

[0022] Embodiment 1

[0023] As Figure 1 shown, a household sweet potato baking oven includes a box body 5, and the box body 5 is an oven in the prior art. Electric heating plates are installed inside three side walls and a top wall of the oven, and the electric heating plates are the electric heating plates used in the oven in the prior art.

[0024] A baking tray 11 is installed inside the box body 5. The baking tray 11 includes a rectangular ring-shaped grill 1 and several support tubes 2, and the support tubes 2 are connected in parallel between the front and rear side walls of the grill 1. Combining Figure 2 it can be seen that the inside of the grill 1 is hollow to form a water storage cavity 10 for holding water. A water filling port (not shown in the figure) is opened at the top of the grill 1, and the water filling port is located outside the grill 1 (on the side close to the box door) so as to supplement water into the water storage cavity 10. Several steam outlet holes 8 are opened on the inner side wall of the grill 1, and the steam outlet holes 8 communicate with the water storage cavity 10. Each support tube 2 is connected to the steam outlet hole 8 through an elastic tube 4. The elastic tube 4 includes a corrugated tube 12 with a sandwich layer. In this embodiment, the corrugated tube 12 is made of an elastic and high-temperature resistant material such as silicone rubber or stainless steel. A spring 6 is installed along the length direction inside the sandwich layer of the corrugated tube 12 to realize the return of the corrugated tube 12.

[0025] Several steam escape holes 3 are opened on the support tube 2, and an adjusting mechanism for adjusting the air outlet volume is installed inside the support tube 2. As Figure 2 shown, the adjusting mechanism includes a flexible tube core 9 installed inside the support tube 2, and the diameter of the tube core 9 gradually decreases from the left end to the right end. The large-diameter end of the tube core 9 is fixedly connected inside the support tube 2, the small-diameter end of the tube core 9 extends into the water storage cavity 10, and a steam outlet channel 7 is formed between the tube core 9 and the inner wall of the support tube 2.

[0026] The specific implementation process is as follows:

[0027] First, fill water into the water storage cavity 10, then place the sweet potatoes on the baking tray 11, close the box door, and start the oven to bake the sweet potatoes. During the baking process, the water in the water storage cavity 10 boils to generate water vapor. The water vapor flows into the support tube 2 through the steam outlet hole 8 and the steam outlet channel 7, and then escapes from the steam escape holes 3 on the support tube 2, and finally drifts onto the sweet potatoes, thereby realizing the supplement of moisture on the surface of the sweet potatoes. Since moisture is supplemented on the surface of the sweet potatoes, it can avoid the sweet potatoes from being burned due to excessive evaporation of moisture on the surface.

[0028] The more sweet potatoes there are, the more water needs to be supplemented, and the more water vapor needs to be dissipated. In this embodiment, since the support tube 2 is connected to the grill 1 through the elastic tube 4, when the sweet potato is placed on the support tube 2, it can press down the support tube 2, thereby stretching the corrugated tube 12 and stretching the spring 6. While the support tube 2 is being pressed down, the tube core 9 can be pulled outwards from the water storage cavity 10. Since the diameter of the tube core 9 gradually decreases from the left end to the right end. Therefore, after the tube core 9 is pulled out, the steam outlet channel 7 (the space between the tube core 9 and the inner wall of the support tube 2) can be increased, thereby increasing the dissipated water vapor, so as to meet the supplement of water vapor when the number of sweet potatoes increases.

[0029] After baking is completed, the box body 5 can be opened to take out the sweet potatoes. The remaining hot water in the water storage cavity 10 can also keep the sweet potatoes on the baking tray 11 that are not eaten in time warm for easy consumption.

[0030] Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that the steam escape holes 3 are opened on the side of the support tube 2, so that the steam escape holes 3 can be prevented from being blocked by the sweet potatoes and affecting the escape of steam. In addition, the baking tray 11 is horizontally slidably connected in the box body 5. Specifically, sliding grooves are opened on the left and right side walls of the oven along the width direction of the oven, and sliders are welded on the left and right side surfaces of the grill 1, and the sliders are slidably connected in the sliding grooves. The sliding setting of the baking tray 11 facilitates pulling out the baking tray 11 to place and take out the sweet potatoes, and a handle (not shown in the figure) is welded on the front side of the grill 1 for the user to hold to pull out the baking tray 11.

[0032] The above are only the embodiments of the present invention, and common knowledge such as the specific structures and characteristics known in the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
