Technical Field
[0001] This utility model belongs to the technical field of kitchen utensils, and specifically relates to an energy-saving and heat-insulating device. Background Technology
[0002] Energy-saving heat preservation equipment mainly refers to kitchen utensils that can maintain the temperature of food and extend the time of food heat preservation. These devices are very practical in homes and the catering industry, and can ensure that food maintains a suitable temperature for a long time, thereby improving the dining experience. Therefore, energy-saving heat preservation equipment is often used in homes and the catering industry to keep food at a suitable temperature for a long time so that it can be eaten.
[0003] Existing energy-saving heat preservation equipment generates heat through built-in electric heating elements (such as resistance wires), which, combined with the blowing of a fan, continuously provides heat to the food. An internal temperature control system automatically adjusts the heating power according to the set temperature to maintain a constant temperature. A vacuum layer is formed between the inner and outer layers, or insulation material is filled to reduce heat conduction and convection. This design effectively prevents heat from transferring from the inside to the outside, thus maintaining the temperature of the food inside. However, during use, because the electric heating elements and the fan are positioned in a fixed manner, the fixed installation position of the heating elements and the fan results in a fixed blowing angle. The degree to which food near the blowing point and food further away from the blowing point are heated differs. When keeping some foods warm for extended periods, the prolonged heating may cause food near the blowing point to overheat, burn, and turn black, leading to spoilage and waste. Utility Model Content
[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an energy-saving heat preservation device that allows hot air to flow evenly and uniformly inside the heat preservation chamber during heat preservation and heating. This effectively ensures that food is baked to the same degree during heat preservation and heating, and effectively prevents food from being overheated and spoiled.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an energy-saving heat preservation device, including a base, with evenly distributed air outlets on the outer side of the base, a heat preservation box on the upper surface of the base, a heating seat on the upper surface of the heat preservation box, symmetrically distributed ventilation openings on the upper surface of the heat preservation box, all of which are connected to the heating seat, an air inlet box in the middle of the upper surface of the heating seat, a resistance wire heating module inside the air inlet box, a fan at the top of the heating seat, symmetrically distributed partitions inside the heat preservation box, a dustproof net in the middle of each partition, a second dustproof net inside a second ventilation opening in the middle of the lower surface of the heat preservation box, evenly distributed placement plates sliding between the partitions, and an air guiding module for guiding air between the heat preservation box and the base.
[0006] As a further improvement of this utility model, the front side of the insulated box is provided with symmetrically distributed door panels, each with a handle in the middle; each door panel is provided with a glass observation window.
[0007] As a further improvement of this utility model, the air guiding module includes a rotating shaft uniformly rotatably disposed between the partition and the inner wall of the adjacent heat preservation box. An air guiding plate is fixedly sleeved in the middle of the outer arc surface of the rotating shaft. An electric control unit for driving the air guiding plate to swing is also disposed between the heat preservation box and the base. The electric control unit includes a drive plate symmetrically fixedly sleeved on the outer arc surface of the rotating shaft. A drive groove is opened in the middle of the drive plate. A guide rail is symmetrically distributed between the partition and the inner wall of the adjacent heat preservation box. A sliding seat is slidably disposed between two adjacent guide rails. A sliding column is uniformly distributed on both the front and rear sides of the sliding seat. The sliding column is respectively installed in conjunction with the adjacent drive groove. An electric control component for driving the sliding seat to move is also disposed on the base. The electric control component includes electric push rods symmetrically disposed inside the base. The telescopic ends of the electric push rods are all connected and fixed to the sliding seat.
[0008] As a further improvement of this utility model, a control box is provided on the front side of the heating base, and the resistance wire heating module, fan and electric push rod are all electrically connected to the control box.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] Firstly, the fan draws outside air into the heating base through the control box. Then, the hot air enters the space between the partition and the inner wall of the insulation box through the ventilation openings on both sides. After blowing over the food, the hot air enters the base through the dustproof net inside the ventilation opening and is finally discharged from the air outlet, thus achieving the purpose of keeping the food warm and heating it.
[0011] Secondly, it allows air to be forced to flow synchronously into the insulation chamber formed by the partitions, so that hot air can flow evenly inside the insulation chamber, which can effectively ensure that the food is baked to the same degree when it is heated.
[0012] Thirdly, the control box regulates the extension and retraction of the electric push rod, causing the sliding seat to rotate through the cooperation of the sliding column and the drive groove, which in turn causes the drive plate to rotate. This, in turn, causes the air guide plate to swing back and forth continuously. The back and forth swing of the air guide plate guides the hot air, allowing it to be blown quickly and evenly onto the food placed on the plate, thus effectively ensuring efficient and uniform heating of the food.
[0013] Fourth, the glass observation window on the door panel allows personnel to better observe the food's temperature control, thus effectively ensuring personnel's control over the food quality. Attached Figure Description

Detailed Implementation
[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.
[0021] like Figure 1 , 4As shown, the device includes a base 101, with evenly distributed air outlets 102 on the outer side of the base 101. An insulation box 103 is mounted on the upper surface of the base 101, and a heating seat 104 is mounted on the upper surface of the insulation box 103. Symmetrically distributed ventilation openings are located on the upper surface of the insulation box 103, and all ventilation openings are connected to the heating seat 104. An air inlet box 105 is located in the middle of the upper surface of the heating seat 104, and a resistance wire heating module is installed inside the air inlet box 105. A fan 113 is located at the top of the heating seat 104. Symmetrically distributed partitions 109 are located inside the insulation box 103, and a dustproof net 110 is installed in the middle of each partition 109. A second dustproof net 111 is installed inside a second ventilation opening in the middle of the lower surface of the insulation box 103. Evenly distributed placement plates 112 are slidably arranged between the partitions 109. An air guiding module for guiding airflow is also provided between the insulation box 103 and the base 101.
[0022] like Figure 1 , 2 As shown, the front side of the insulated box 103 is provided with symmetrically distributed door panels 106, and each door panel 106 is provided with a handle 108 in the middle.
[0023] like Figure 2 , 3 As shown, the air guiding module includes a rotating shaft 201 uniformly rotatably disposed between the partition 109 and the inner wall of the adjacent heat preservation box 103. Air guiding plates 202 are fixedly sleeved on the middle of the outer arc surface of the rotating shaft 201. An electronic control unit for driving the air guiding plates 202 to swing is also disposed between the heat preservation box 103 and the base 101. The electronic control unit includes a drive plate 203 symmetrically fixedly sleeved on the outer arc surface of the rotating shaft 201. A drive groove 204 is opened in the middle of the drive plate 203. The partition 109 and the inner wall of the adjacent heat preservation box 103... Symmetrically distributed guide rails 205 are provided between the base 101, and a sliding seat 206 is slidably provided between each pair of adjacent guide rails 205. Sliding columns 207 are evenly distributed on both the front and rear sides of the sliding seat 206. The sliding columns 207 are respectively installed in conjunction with the adjacent drive grooves 204. An electrical control component for driving the sliding seat 206 to move is also provided on the base 101. The electrical control component includes electric push rods 208 symmetrically arranged inside the base 101. The telescopic ends of the electric push rods 208 are all connected and fixed to the sliding seat 206.
[0024] like Figure 1 , 2 As shown, a control box 301 is provided on the front side of the heating base 104, and the resistance wire heating module, the fan 113 and the electric push rod 208 are all electrically connected to the control box 301.
[0025] In use, the operator pulls handle 108 to rotate door panel 106, then places the food to be kept warm on placement plate 112, and then pulls handles 108 on both sides to rotate door panel 106 to close the insulated box 103. The control box 301 regulates the operation of the resistance wire heating module, fan 113, and electric push rod 208, causing fan 113 to draw outside air into the heating base 104. The resistance wire heating module heats the drawn-in air, and the hot air enters the space between partition 109 and the inner wall of insulated box 103 through vents on both sides. It then passes through dustproof net 110 and is blown onto the food placed on placement plate 112 to keep it warm. After passing over the food, the hot air passes through dustproof net 111 inside vent 2 and enters the interior of the base, finally exiting from air outlet 102. This blowing method allows for synchronous forced airflow. The insulating chamber formed between the partitions 109 allows hot air to flow evenly and uniformly within it, effectively ensuring that the food is baked to the same degree during the heating process. The control box 301 controls the extension and retraction of the electric push rod 208, causing it to slide the sliding seat 206 between the two guide rails 205. This causes the sliding seat 206 to move the sliding column 207 within the drive groove 204. Consequently, the sliding seat 206, through the cooperation of the sliding column 207 and the drive groove 204, causes the rotating shaft 201 containing the drive plate 203 to rotate. This, in turn, causes the rotating shaft 201 to continuously oscillate the air guide plate 202. The oscillation of the air guide plate 202 continuously guides the hot air, allowing it to be quickly and evenly blown onto the food placed on the placement plate 112, thus effectively ensuring efficient and uniform heating of the food.
[0026] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, each door panel 106 is equipped with a glass observation window 107. During use, the glass observation window 107 on the door panel 106 allows personnel to better observe the temperature of the food, thereby effectively ensuring personnel's control over the food quality.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
