Description

Technical Field

[0001] The invention belongs to the field of gas stove devices, and in particular relates to a novel heat flow control energy-saving protection device for a gas stove. Background Art

[0002] As a common kitchen appliance, gas stoves provide heat for cooking by burning gas. Due to its convenience, environmental protection and strong controllability, they are widely used in various scenarios. After years of use, it is found that the following problems may occur during the use of gas stoves. During the combustion of gas, due to the flat or round bottom of the pot, the flame will spread outward after contacting the bottom of the pot, heating the bottom of the pot as a whole. However, when the flame is large, the spreading flame will rise to the upper end of the pot wall, causing the pot wall to rise to a higher temperature in a short time. However, the pot wall does not participate in the heating of the ingredients during the cooking process. After the firepower is increased to a certain level, the heating effect of the upward increase is not obvious, and most of the energy is completely wasted, which increases the gas cost and cannot achieve the best heating efficiency. At the same time, this part of the wasted energy will also be dissipated to the surroundings, such as the pot handle, pot lid and surrounding space, causing the temperature of these parts and areas to rise to a high level, making it difficult for the cook to operate, and even causing scalding accidents. The existing gas stove wind shield only covers the edge of the gas stove burner to prevent the surrounding airflow from affecting the burning flame. The flame will still spread during the cooking process. In addition to reducing the external influence on the flame during combustion, the above problems still exist. Therefore, the present invention studies the heat flow control method of the gas stove and develops an energy-saving protection device that can effectively control the heat flow. Summary of the invention

[0003] The present invention provides a new type of heat flow control energy-saving protection device for a gas stove. The main part is a control cover, which is composed of a chassis and a side wall. A round hole is opened in the center of the chassis, and the round hole allows the burner of the gas stove to pass through it, so that the combustion part of the gas stove is covered in the middle. The outer contour of the chassis is circular to adapt to the shape of a commonly used heating container. The side wall is arranged on the chassis so that the side wall surrounds the outer circumference of the chassis, so that the side wall and the chassis form a combustion space with an upper opening. In order to solve the problem of heat diffusion during combustion, it is necessary to control the outer flame with a higher temperature to the part that needs to be heated, recycle the energy to be diffused, and improve the energy utilization rate. In order to achieve the above effect, the chassis and the side wall should have a special angle inside, wherein the upper surface of the chassis is inclined upward from the inside to the outside, and the inner side of the side wall is inclined inward from the bottom to the top. When viewed from the side, the overall shape of the internal space of the control cover presents a style of being narrow at the bottom, wide in the middle and narrow at the top. In order to prevent the control cover from blocking the air during operation and causing insufficient oxygen required for combustion, a ring wall is set below the round hole, and a plurality of evenly distributed air intake holes are set on the chassis. The control cover is placed on the burner of the gas stove using the ring wall. During the combustion process, air can continuously enter the control cover from the air intake holes to supplement the oxygen required for combustion.

[0004] When gas burns, carbon dioxide gas is produced. If it is not discharged in time, the combustion effect will be affected. In order to discharge the exhaust gas such as carbon dioxide produced by combustion in time, an exhaust port is set on the side wall of the control cover. In this way, the oxygen required for combustion is supplemented from the air inlet, and the exhaust gas produced is discharged in an orderly manner from the outlet, forming an air flow channel to improve the gas combustion efficiency.

[0005] When cooking, different fire powers are adjusted according to needs. When the fire power is adjusted to the maximum, one air outlet is difficult to meet the exhaust needs, so the number of air outlets is set to multiple to improve the exhaust efficiency.

[0006] When the gas stove is at a high power, part of the burning flame and heat will overflow from the air outlet. If the air outlet is facing the cook, the heat generated will affect the human body. Therefore, all the air outlets are set on the same side of the side wall. When installing the control cover, all the air outlets are set on the side away from the operator to avoid the overflowing energy from affecting the cook.

[0007] In order to install the control cover more stably and improve the combustion efficiency of the gas, a bracket is set up for installing the control cover. The bracket consists of a base frame and a support arm. The number of the support arms is more than 3. The support arms are fixed on the base frame in a radial shape, and the control cover can be placed on the support arms through the ring wall. When installing the control cover, first set the bracket on the burner, and then place the control cover on the bracket, so that there is a certain gap between the bottom of the control cover and the stove surface of the gas stove, and the round hole in the middle of the chassis becomes an air channel, increasing the contact surface between the burner and oxygen.

[0008] As the best shape of the bracket, the support arm is set to an inverted L shape, so that one side of the support arm is vertically connected to the base frame, and the other side of the support arm is parallel to the horizontal plane and faces the center of the circular hole. Multiple support arms form multiple support points to provide a placement surface for the control cover. At the same time, a pot rack is set above the end of the horizontal side of the support arm, so that the pot rack and the support arm form an upward step shape. Since the multiple support arms are radially arranged, the multiple pot racks on the support arms are also radially arranged. Therefore, the multiple pot racks are equivalent to being arranged on a circle with the circular hole as the center. The distance from the outer end face of the pot rack to the center of the circular hole is equivalent to the maximum radius of the circle. The equivalent radius formed by the pot rack is consistent with the radius of the circular hole, so that the multiple pot racks can pass through the circular hole. The cross section formed by the pot rack and the support arm can be used to fix the control cover on the support arm without displacement. The pot rack extending into the control cover can be used to support the pot during cooking.

[0009] In order to better fix the control cover and prevent it from rotating during use, a card slot is set on the ring wall below the control cover. There are multiple card slots and they correspond to the pot racks one by one, so that the pot rack can pass through the card slots from under the card slots, and the card slots are used to limit the displacement of the control cover.

[0010] Since the bracket raises the position of the control hood, there is a certain distance between the control hood and the stove surface of the gas stove. Air can enter the round hole from the distance, and the flame will be disturbed during the air flow. In order to avoid the above problem, the dimensions of the bracket and the ring wall are set to ensure that when the control hood is installed on the burner of the gas stove, the lower end of the ring wall is lower than the air outlet on the burner. In this way, when the air rushes into the round hole, the air directly rushing to the air outlet will be blocked by the ring wall, and the blocked air will only enter the round hole from bottom to top, avoiding interference with the flame in the combustion chamber.

[0011] In order to provide a better fixing effect, a non-slip soft rubber is provided on the bottom surface of the base frame to prevent the bracket from sliding on the gas stove top during use.

[0012] The novel heat flow control energy-saving protection device for gas stoves provided by the present invention has the following beneficial effects: 1. Recycle the energy generated by combustion to ensure that most of the energy can be used for cooking and heating, improve the energy utilization rate of gas combustion, and reduce resource consumption under the same circumstances.

[0013] 2. The air outlet, air inlet and bracket arranged on the device can improve the air circulation effect and increase the oxygen intake, thus solving the problem of incomplete gas combustion during the use of ordinary wind shields and increasing the combustion efficiency of the gas.

[0014] 3. By recycling energy to avoid heat leakage, effectively blocking heat and preventing it from being transferred to the surrounding environment, the problem of hot handles, spatulas, pot ears and pot bodies can be solved. It can prevent high temperature from directly reaching the operator, reduce the risk of physical damage to the human body, and improve cooking safety performance.

[0015] 4. During the cooking process, the pot can be well fixed so that the bottom of the pot is fully supported on the device to prevent the pot from sliding during cooking.

[0016] 5. The combination of the bracket and the control cover can adapt to different types of pots and pans, and the same set of equipment can be used to complete cooking tasks with different needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] To further illustrate the concept of the present invention, the specific implementation of the present invention will be further described below in conjunction with the accompanying drawings: Embodiment 1

[0020] A new type of heat flow control energy-saving protection device for gas stoves, such as Figure 1As shown, the control cover 1 as a whole is composed of a chassis 2 and a side wall 3, and the whole is formed in one piece by a casting or stamping process. The chassis 2 is disc-shaped with a higher periphery than the middle, and the inclination angle of the chassis 2 relative to the horizontal plane is 15°. The side wall 3 extends upward from the periphery of the chassis 2, and the side wall 3 is inclined inward as a whole, and the angle between the side wall 3 and the horizontal plane is 72°. Figure 2 As shown, a circular hole 4 is opened in the middle of the chassis 2, and the diameter of the circular hole 4 is set according to the size of the burner of the gas stove so that the burner can be completely inserted into the circular hole 4, and then a circle of annular wall 5 is set downward around the circular hole 4, and a plurality of air inlet holes 6 are opened on the disk surface of the chassis 2, and the air inlet holes 6 are evenly distributed along two concentric rings with the center of the circular hole 4 as the center.

[0021] When in use, the control cover 1 is covered from above the burner, and the burner is completely covered in the middle of the annular wall 5. The control cover 1 is placed on the gas stove through the annular wall 5. During the cooking process, the flame is guided back to the bottom of the pot under the guidance of the bottom plate 2 and the side wall 3, and the energy originally dissipated is reused for heating, thereby improving the heating efficiency. At the same time, air is replenished from the air inlet 6 to provide oxygen required for combustion. Embodiment 2

[0022] A new type of heat flow control energy-saving protection device for a gas stove, based on the first embodiment, the angle between the side wall 3 and the horizontal plane is adjusted to 78°, the angle between the bottom plate 2 and the horizontal plane is adjusted to 11°, and an air outlet 7 is opened on the side wall 3, the number of the air outlets 7 is 5, and the positions of the openings ensure that the air outlets 7 are located on the same side of the side wall 3, so that there is no air outlet 7 on a section of the side wall 3, such as Figure 3 shown.

[0023] During use, the control cover 1 is rotated to the side where the air outlet 7 is completely away from the operator, and the carbon dioxide and other gases produced by combustion can be discharged from the air outlet 7, forming convection between the air outlet 7 and the air inlet 6, increasing the amount of oxygen replenishment and improving the combustion effect. At the same time, the heat on the side of the control cover 1 facing the operator is blocked by the side wall 3 to prevent the heat from rushing to the operator. Embodiment 3

[0024] On the basis of the second embodiment, the angle between the side wall 3 and the horizontal plane is adjusted to 75°, the angle between the bottom plate 2 and the horizontal plane is adjusted to 15°, and a bracket 8 is added. The bracket 8 is composed of a base frame 9 and a support arm 10. The base frame 9 is a square frame, and a circle of non-slip soft glue 13 is adhered to the bottom surface of the base frame 9. The support arm 10 is four inverted L-shaped metal rods, and the four support arms 10 are respectively welded to the midpoints of the four sides of the base frame 9, so that one side of the support arm 10 is perpendicular to the bracket 8, and the other sides are all facing the center of the base frame 9. Then, a trapezoidal metal block is welded to the end facing inward above the support arm 10 as a pot rack 11. When welding, the distance between the outermost end of the pot rack 11 and the center of the base frame 9 is consistent with the radius of the circular hole 4, as shown in FIG. Figure 5Then four slots 12 are opened on the ring wall 5, and the slots 12 are distributed in a cross shape, and the slots 12 can just allow the pot rack 11 to pass through. Figure 4 shown.

[0025] First, the bracket 8 is covered from above the burner, so that the bottom frame 9 frames the burner inside, and then the control cover 1 is installed on the bracket 8. During installation, the pot rack 11 is passed through the slot 12 of the ring wall 5, and the position of the control cover 1 is fixed by the slot 12 and the pot rack 11. Figure 6 As shown. It should be noted that when setting the annular wall 5 and the bracket 8, the height of the annular wall 5 and the height of the arm 10 of the bracket 8 should be adjusted so that when the control cover 1 is installed on the bracket 8, the lower end surface of the annular wall 5 is lower than the air outlet on the burner. Then adjust the angle of the bracket 8 so that all the air outlets 7 on the control cover 1 are away from the side where the personnel operate, and place the pot on the pot wall of the bracket 8 when cooking. During the combustion process, the air intake channel is the air intake hole 6 and the circular hole 4 under the control cover 1, and then the exhaust gas is discharged from the air outlet 7, which greatly improves the air convection efficiency and can achieve the best combustion effect. The annular wall 5 can also prevent the air from blowing directly horizontally to the flame on the burner air outlet during the air convection process, reducing the interference of the flame during the combustion process.

[0026] The device in Example 3 was tested, and a water boiling test was conducted on the same gas stove. A carbon monoxide detector was set at the installation location of the household gas alarm device. Water was boiled in a normal manner and by using the device in Example 3. The experiment was conducted in two ways: boiling soup and cooking. The full combustion efficiency of the gas was determined by detecting carbon monoxide, and the required energy consumption was determined by the time it took for the water to boil. After the experiment, under the same conditions, when boiling water in the normal manner, the average time required to boil water was 8 minutes and 46 seconds, while the average time required to boil water by using the device provided in Example 3 was 7 minutes and 24 seconds, which was about 20% energy-saving compared to the normal water boiling method. Without turning on the range hood, the carbon monoxide concentration measured by the water boiling method in Example 3 was 12PPM, and when the range hood was turned on, it was 0PPM. The lower limit of the alarm in the national standard is 50PPM, and the upper limit is 500PPM. This detection value fully meets the requirements of international standards.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various changes and variations may occur. Any modifications, equivalent substitutions, improvements, etc. made using the present invention should be included in the scope of protection of the present invention.
