Description

Technical Field

[0001] This utility model relates to the field of electric heater technology, and in particular to an electric heater that prevents burns. Background Technology

[0002] Electric heaters are efficient and convenient heating devices, mainly used to provide indoor heating in cold seasons. They can quickly convert electrical energy into heat energy, raising the indoor temperature in a short time and providing users with a comfortable indoor environment.

[0003] Most electric heaters nowadays have relatively simple protective structures, often only protecting the heating element through the outer shell. When in use, the area that emits heat is often very hot, and this area is mostly directly exposed, making it easy for people to touch it, which may result in burns and affect the safety of using the electric heater.

[0004] Therefore, given that the existing electric heaters have relatively simple protective structures, making it easy for people to be burned, anti-scalding electric heaters can be designed. By guiding the hot air out from a concealed location, the possibility of operators touching high-temperature areas can be effectively reduced, and the warm air can be evenly discharged from the electric heater, improving the safety of electric heater use and thus effectively enhancing the practical value of electric heaters. Utility Model Content

[0005] In order to overcome the problem that most electric heaters have relatively simple protective structures, making it easy for people to touch the high-temperature areas and suffer burns, resulting in low safety during use, this utility model is proposed.

[0006] The technical solution of this utility model is as follows: an anti-scalding electric heater, comprising a base, a shell, an electric heating mechanism, an electric heating component, a moving component, a protective top cover, a first air guiding chamber, an air guiding component, an air inlet slot, a protective side plate, a second air guiding chamber, an air outlet slot, and an air guiding plate. The shell is provided on the upper surface of the base, the moving component is provided on the bottom surface of the base, the electric heating mechanism is provided on the inner side of the shell, the electric heating component is provided on one side of the electric heating mechanism, the protective top cover is provided on the top of the shell, the first air guiding chamber is provided on the inner side of the protective top cover, the air guiding component is provided on the inner side of the first air guiding chamber, the air inlet slot is provided on the bottom surface of the protective top cover, the protective side plate is provided on the outer side of the protective top cover, the second air guiding chamber is provided on the inner side of the protective side plate, the air outlet slot is provided on the bottom surface of the protective side plate, and the air guiding plate is provided on the bottom surface of the protective side plate.

[0007] Preferably, the base position is flexibly moved by a movable component to ensure stable placement. The base provides fixed support for the housing, which in turn protects the electric heating mechanism. The electric heating component controls the temperature rise of the electric heating mechanism, and the housing is further protected by a protective top cover and protective side panels. The housing, protective top cover, and protective side panels are made of heat-insulating materials to prevent personnel from touching the high-temperature parts of the housing. The hot air generated by the electric heating mechanism is drawn in by a guide component, and the warm air enters the first guide chamber through the air inlet slot. The warm air in the first guide chamber is naturally diverted to the second guide chamber and discharged through the air outlet slot, thus warming the environment. The warm air discharged from the air outlet slot has its blowing path changed by a guide plate to prevent the warm air from blowing directly onto the base plate, thereby effectively reducing the possibility of operators touching high-temperature areas and ensuring that the warm air is evenly distributed from the electric heater, improving the safety of the electric heater.

[0008] As a preferred option, multiple sets of air inlet slots are provided, protective side plates are inclined at a certain angle around the protective top cover, the second air guide chamber is connected to the first air guide chamber, and the air guide plate is set in a V-shape at a certain angle on one side of the air outlet slot.

[0009] Preferably, the moving component includes omnidirectional casters, and the bottom surface of the base is provided with omnidirectional casters. Multiple sets of omnidirectional casters are provided, and the omnidirectional casters are located at the four corners of the base.

[0010] Preferably, the moving component also includes a wedge block, an electric telescopic rod, and a supporting base plate. A wedge block is provided on one side of the housing, and two sets of wedge blocks are symmetrically arranged. An electric telescopic rod is provided on one side of the inclined surface of the wedge block, and a supporting base plate is provided at one end of the electric telescopic rod.

[0011] Preferably, the electric heating component includes a control panel and a protective grille, with the control panel located on one side of the housing and the protective grille located on the top of the housing.

[0012] Preferably, the flow guiding component includes a support rod, the upper surface of the base is provided with the support rod, multiple sets of support rods are provided, and a protective top cover is provided at one end of the support rod.

[0013] Preferably, the flow guiding assembly also includes a protective cover and an exhaust fan. The top of the inner side of the first flow guiding chamber is provided with a protective cover, and two sets of protective covers are symmetrically arranged. An exhaust fan is provided on the inner side of the protective cover.

[0014] The beneficial effects of this utility model are:

[0015] When heating, the electric heating mechanism is protected by the casing. After the base is moved to the designated position, the electric heating mechanism is controlled to raise the temperature. The casing is protected by a protective top cover and protective side panels. The casing, protective top cover, and protective side panels are made of heat-insulating materials to prevent people from touching the high-temperature parts of the casing. The hot air generated by the electric heating mechanism is drawn in and directed into the first air guide chamber through the air inlet slot. The warm air in the first air guide chamber is naturally diverted to the second air guide chamber and discharged through the air outlet slot, thus warming the environment. The warm air discharged from the air outlet slot is deflected by the guide plate to change its blowing path, preventing the warm air from blowing directly onto the base plate. This solves the problem that most electric heaters only protect the heating element with the casing. When in use, the temperature of the heat-emitting part is often high, and this part is mostly directly exposed, making it easy for people to touch and causing burns. This improves the safety of electric heaters. Attached Figure Description

The housing 2 is disposed on the upper surface of the base 1, and the movable component is disposed on the bottom surface of the base 1. The electric heating mechanism 3 is disposed inside the housing 2, and the electric heating component is disposed on one side of the electric heating mechanism 3. The protective top cover 4 is disposed above the housing 2, and the inner side of the protective top cover 4 is provided with... The first flow guide chamber 5 has a flow guide component on its inner side. The bottom surface of the protective top cover 4 has an air inlet slot 6, which has multiple sets. The outer side of the protective top cover 4 has a protective side plate 7, which is inclined at a certain angle around the protective top cover 4. The inner side of the protective side plate 7 has a second flow guide chamber 8, which is interconnected with the first flow guide chamber 5. The bottom surface of the protective side plate 7 has an air outlet slot 9, and the bottom surface of the protective side plate 7 has a flow guide plate 10, which is V-shaped at a certain angle and located on one side of the air outlet slot 9.

[0023] Please see Figure 2 In this embodiment, the moving assembly includes universal casters 201, wedge blocks 202, an electric telescopic rod 203, and a support base plate 204. Universal casters 201 are provided on the bottom surface of the base 1, with multiple sets of universal casters 201 positioned at the four corners of the base 1. Two sets of wedge blocks 202 are symmetrically arranged on one side of the housing 2. An electric telescopic rod 203 is provided on one inclined side of the wedge block 202, and a support base plate 204 is provided at one end of the electric telescopic rod 203. Rotating the universal casters 201 allows the base 1 to be moved flexibly, and the electric heater can be moved to the designated position. The electric telescopic rod 203 is fixed in position by wedge block 202, so that the electric telescopic rod 203 is tilted downward at a certain angle. The height of the support base plate 204 is adjusted by telescopic electric telescopic rod 203. The support base plate 204 supports and fixes the base 1, ensuring that the base 1 is placed stably and avoiding tipping over. The electric heating component includes control panel 301 and protective grille 302. Control panel 301 is provided on one side of housing 2, and protective grille 302 is provided on the top of housing 2. The heating state of electric heating mechanism 3 can be flexibly controlled by control panel 301. The protective grille 302 is used to cover the top of housing 2 and protect electric heating mechanism 3 inside.

[0024] Please see Figures 3-4In this embodiment, the flow guiding assembly includes a support rod 501, a protective cover 502, and an exhaust fan 503. The upper surface of the base 1 is provided with a support rod 501, and multiple sets of support rods 501 are provided. The protective top cover 4 is provided at one end of the support rod 501. The top of the inner side of the first flow guiding chamber 5 is provided with a protective cover 502, and two sets of protective covers 502 are symmetrically arranged. The exhaust fan 503 is provided inside the protective cover 502. The protective top cover 4 is supported and fixed by the support rod 501. The exhaust fan 503 is protected inside by the protective cover 502. When the exhaust fan 503 is started, it draws out the hot air generated by the electric heating mechanism 3. After the electric heating mechanism 3 is started, the hot air is continuously drawn into the first flow guiding chamber 5 to ensure continuous air flow.

[0025] Before heating, rotate the universal stop wheel 201 to move the base 1 to the designated position, lock the universal stop wheel 201, and then extend the electric telescopic rod 203 on the wedge block 202 so that the support base plate 204 contacts the ground.

[0026] When heating, the temperature of the electric heating mechanism 3 inside the housing 2 is increased by controlling the control panel 301. The hot air generated by the heating passes through the protective grille 302 and enters the area below the protective top cover 4 and the protective side plate 7 supported by the support rod 501. The exhaust fan 503 inside the protective cover 502 is started to draw the hot air into the first guide chamber 5 through the air inlet slot 6.

[0027] Subsequently, the hot airflow in the first guide chamber 5 is diverted to the second guide chamber 8 of the protective side plate 7, discharged through the air outlet 9, and the hot air blowing path is changed by the guide plate 10.

[0028] Through the above steps, the position of the base 1 is flexibly moved by the movable component to ensure the stable placement of the base 1. The base 1 is used to fix and support the shell 2, and the shell 2 protects the electric heating mechanism 3. The electric heating component controls the temperature rise of the electric heating mechanism 3. The shell 2 is protected by the protective top cover 4 and the protective side plate 7. The shell 2, the protective top cover 4, and the protective side plate 7 are made of heat-insulating materials to prevent personnel from touching the high-temperature parts of the shell 2. The hot air generated by the electric heating mechanism 3 is drawn in by the air guide component, and the warm air enters the first air guide chamber 5 through the air inlet slot 6. The warm air in the first air guide chamber 5 is naturally diverted to the second air guide chamber 8 and discharged through the air outlet slot 9 to heat the environment. The warm air discharged from the air outlet slot 9 passes through the air guide plate 10 to change the blowing path, preventing the warm air from blowing directly on the bottom plate, thereby effectively reducing the possibility of the operator touching the high-temperature area and ensuring that the warm air is evenly discharged from the electric heater.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
