Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a stove heater. Background Art

[0002] Open flame heaters are a common traditional device for keeping warm. Although they have low heating efficiency (most of the hot air is discharged to the outside through the chimney), poor hygiene (combustion produces soot), and high economic costs (the price of fuel is higher than the electricity bill), watching the dancing flames while sitting around the fire and chatting with family over a winter night can make people feel warm and comfortable.

[0003] Although it is comfortable to sit around a fire, if you do not pay attention to ventilation, it may cause carbon monoxide poisoning. Nowadays, the urbanization rate is getting higher and higher, the per capita living area is compressed, and the housing area of ​​ordinary urban residents is much smaller than the rural housing area in the past. Incidents of serious consequences caused by fire poisoning often occur. Therefore, open flame heaters have been basically eliminated in urban housing, and electric heaters have been rapidly developed as an alternative.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] It should be noted that, in this document, relational terms such as “first” and “second” are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.

[0034] Example 1

[0035] The present application embodiment provides a stove heater, referring to Figure 1 and Figure 2 The stove heater comprises a base 1, a bracket 3, a heating element 2, a protective net 4, a table top 5 and a bottom plate 6; the upper surface of the base 1 is horizontal and fixed with the bracket 3; a horizontal bottom plate 6 is fixed on the top of the bracket 3, a horizontal table top 5 is arranged directly above the bottom plate 6, and a vertical heating element 2 and a protective net 4 are fixed between the bottom plate 6 and the table top 5. A circular connecting block 41 is welded and fixed to the top of the protective net 4 along its circumference, and the connecting block 41 is detachably connected to the table top 5 by screws; the bottom of the protective net 4 is welded and fixed to the upper surface of the bottom plate 6.

[0036] The heating element 2 has two forms: Figure 3 One is that a tube groove 231 is provided on the inner wall of the metal cylinder 23, and a metal heating tube is inserted into the tube groove 231. In this form of the heating element 2, the top end of the metal cylinder 23 is directly fixed to the lower surface of the table board 5, and the bottom end is fixed to the upper surface of the bottom plate 6; Figure 4 The other is that a metal cylinder 23 is arranged inside a quartz tube 24, the inner wall of the quartz tube 24 is coated with a graphene heating layer, and an insulating coating is coated or a mica plate is sandwiched between the quartz tube 24 and the metal cylinder 23.

[0037] Reference Figure 2 When the heating element 2 is in the form of a double-layer tube of a quartz tube 24 and a metal cylinder 23 , the heating element 2 is fixed between the table top 5 and the bottom plate 6 using a first limiting ring 61 , a first gasket ring 62 , a second limiting ring 51 and a second gasket ring 52 .

[0038] Reference Figure 5 A first limiting ring 61 and a first gasket ring 62 are fixed on the upper surface of the bottom plate 6. The first limiting ring 61 is coaxial with the first gasket ring 62. The first gasket ring 62 is located on the outer side of the first limiting ring 61. The first gasket ring 62 has a first slot 621. The quartz tube 24 is a cylinder with a similar shape to the metal cylinder 23. There is a uniform gap between the outer wall of the metal cylinder 23 and the inner wall of the quartz tube 24. The quartz tube 24 and the metal cylinder 23 are both coaxial with the first limiting ring 61. The outer wall of the bottom of the metal cylinder 23 fits in with the inner ring surface of the first limiting ring 61, and the bottom of the quartz tube 24 fits in with the first slot 621.

[0039] Reference Figure 6A second limiting ring 51 and a second gasket 52 are fixed on the lower surface of the table top 5. The second limiting ring 51 is coaxial with the second gasket 52. The second gasket 52 is located on the outer side of the second limiting ring 51. The second gasket 52 has a second groove 521. The inner wall of the top of the metal cylinder 23 fits in with the outer ring surface of the second limiting ring 51, and the top of the quartz tube 24 fits in with the second groove 521.

[0040] Reference Figure 5 and Figure 6 By changing the thickness of the second gasket 52 or the first gasket 62, the installation of quartz tubes 24 of different lengths can be adapted; since the top inner wall of the quartz tube 24 is limited by the inner wall of the second slot 521, and the bottom inner wall of the quartz tube 24 is limited by the inner wall of the first slot 621, the quartz tube 24 can be fixed between the table top 5 and the bottom plate 6; the metal cylinder 23 can be fixed between the table top 5 and the bottom plate 6 by limiting the inner wall of the metal cylinder 23 by the second limiting ring 51 and limiting the outer wall of the metal cylinder 23 by the first limiting ring 61.

[0041] Reference Figure 1 The bracket 3 is composed of multiple (at least three) pillars 31, all of which stand vertically between the base 1 and the bottom plate 6. The lower surface of the bottom plate 6 has sleeves 63 corresponding to the number of the pillars 31. The top end of the pillar 31 is inserted into the sleeve 63 and fixed, and the bottom end of the pillar 31 is fixedly connected to the base 1 with bolts.

[0042] Reference Figure 7 The support 31 is a hollow tube with an open top. The first limiting ring 61 has a circular hole 611 connected to the top end of the support 31. The cable of the heating element 2 is introduced into the support 31 through the circular hole 611 and led out from the base 1 to connect to the power supply.

[0043] Reference Figure 2 The bottom opening of the heating element 2 is an air inlet 21, and there is a gap for air intake between the air inlet 21 and the upper surface of the base 1, and the top opening of the heating element 2 is an air outlet 22; the protective net 4 is also a straight cylinder, and the protective net 4 can be a square cylinder or a cylinder. The protective net 4 is sleeved on the outside of the heating element 2 and the two are coaxial, and the protective net 4 maintains a safe distance from the outer wall of the heating element 2; a through hole is opened in the center of the bottom plate 6 to expose the air inlet 21; the table board 5 is used as a small tea table for placing food and tea cups, and can be made of metal or wood. A through hole is also opened in the center of the table board 5 to expose the air outlet 22, and the hot air discharged from the air outlet 22 fumes the table board 5, so that the table board 5 is heated, thereby keeping the food and tea placed on the table board 5 warm.

[0044] Reference Figure 2When the stove heater of this embodiment is working, indoor air enters the heating element 2 from the air inlet 21, and the hot air heated by the heating element 2 is discharged from the air outlet 22, forming a chimney effect; while the heating element 2 radiates heat to the surrounding of the electric heater, it also continuously circulates and heats the air around the stove through the chimney effect, so the heating efficiency of the air around the stove is high. The heat radiation of the heating element 2 and the hot air discharged from the air outlet 22 will also affect the table board 5, causing the table board 5 to heat up, so that people can use the table board 5 to keep food and tea warm while heating around the stove.

[0045] Reference Figure 2 In order to prevent the food on the table 5 from falling into the heating element 2 from the air outlet 22, a grid frame 8 is fixed in the center of the table 5, and the grid frame 8 is used to cover the air outlet 22 of the heating element 2. The grid frame 8 protrudes from the upper surface of the table 5 in a shroud shape, and the protrusion height should be sufficient: even if a person accidentally presses on the top of the grid frame 8, he will not be burned by the hot air discharged from the air outlet 22. Nuts, fruits and other food materials can also be placed on the grid frame 8 for heating.

[0046] The main innovation of the stove heater proposed in the embodiment of the present application is:

[0047] 1. Use a hollow cylindrical heating element to form a chimney effect. Part of the heat is convected upward in the heating element along with the air, which heats the space and the food on the grid on top of the heating element at the same time;

[0048] 2. The cylindrical heating element can radiate heat 360 degrees horizontally, giving people the feeling of warming up around a fire. Another part of the heat rises to heat the table top, thereby achieving the purpose of heating the food on the table.

[0049] Example 2

[0050] The embodiment of the present application provides a stove heater based on the embodiment 1, which is different from the embodiment 1 in that the bottom of the protective net 4 and the bottom plate 6 are not welded, but are plug-in-fitted for easy assembly and disassembly.

[0051] Reference Figure 8 An annular protrusion 64 is fixed on the upper surface of the bottom plate 6 around the heating element 2. The protrusion 64 has a slot 641 for inserting the bottom end of the protection net 4. The protection net 4 and the slot 641 are interference fit in a plug-in manner.

[0052] Example 3

[0053] The present application embodiment provides a stove heater based on the embodiment 1, referring to Fig. 9, a display screen 7 and a controller are added. The display screen 7 is a straight cylinder, the display screen 7 is coaxial with the heating element 2, the display screen 7 is fixed to the lower surface of the bottom plate 6, the bracket 3 can extend into the space surrounded by the display screen 7 and be fixedly connected to the bottom plate 6, and the display screen 7 can also be fixedly connected to the top of the bracket 3 after the bottom is sealed. The controller is used to control the display screen 7 to display a static picture or dynamic video of the flame. The controller is hidden inside the base 1 and connected to the display screen 7 through a cable. The display screen 7 is one of a lamp bead board, an LCD screen, an LED screen or an OLED screen, among which the lamp bead board is the most stable and durable, and is least affected by the thermal radiation of the heating element 2, while the OLED screen has good color saturation and vividness, and the flame display effect is more realistic. Considering that the LCD screen, LED screen or OLED screen has a high cost and a greatly reduced service life at high temperatures, the present embodiment preferably uses a flexible lamp bead board as the display screen 7, and selects high temperature resistant LEDs as lamp beads.

[0054] Since the air inlet 21 (see Figure 2 ) The air intake flow rate needs to be ensured, so a sufficiently large air intake gap is left between the bottom end of the display screen 7 and the upper surface of the base 1. If the display screen 7 is sealed with a bottom plate, a central hole needs to be reserved on the bottom plate for air intake 21.

[0055] The stove heater provided in the embodiment of the present application uses the display screen 7 to display the flame image without using an open flame, so that the bottom of the electric heater can also have a visual effect of simulating flames, and can create the illusion that there is a burning cavity at the bottom of the electric heater, allowing users to recall the warmth when using a traditional open flame heater, making the user feel warm and comfortable.

[0056] Example 4

[0057] The present application embodiment provides a stove heater based on the embodiment 1, referring to Fig.10 , a transparent plate 9, a resin block 10 and a lamp 11 are added. The transparent plate 9 is a straight cylinder and is coaxial with the heating element 2. The transparent plate 9 is fixed to the lower surface of the bottom plate 6. The bracket 3 can extend into the space surrounded by the transparent plate 9 and be fixedly connected to the bottom plate 6. The transparent plate 9 can also be fixedly connected to the top of the bracket 3 after the bottom is sealed.

[0058] Since the air inlet 21 (see Figure 2 ) It is necessary to ensure the air intake flow, so a sufficiently large air intake gap is left between the bottom end of the transparent plate 9 and the upper surface of the base 1. If the transparent plate 9 is sealed with a bottom plate, a central hole needs to be reserved on the bottom plate for air intake through the air inlet 21.

[0059] Reference Fig.10The resin block 10 is formed by solidifying the resin poured from the mold, and the lamp 11 is embedded in the resin block 10. The shape and color of the resin block 10 imitate the burning carbon block. When the lamp 11 is lit, it can simulate the scene of the carbon block burning red. The user sees the resin block 10 through the transparent plate 9 as a red-hot carbon block, which makes the user feel the heat radiation like a warm fire, and the body feels like a real stove.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
