Technical Field

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

[0002] A heater refers to a device used for heating. There are various types of heaters. The most common electric heater is a heating device that uses electricity as an energy source for heating and can be widely used in various civil and public buildings such as residences, offices, hotels, shopping malls, hospitals, schools, and train carriages for mobile heating, simple movable houses, etc.

[0003] Most of the existing heaters use resistance wires and carbon fibers as heating elements. Using resistance wires as heating elements has many drawbacks: when a resistance wire is under an externally applied alternating electric field, inductive reactance is generated, causing a part of the electrical energy to be lost as reactive power; the heating and cooling are slow, and there are phenomena such as redness and incandescence, posing certain safety hazards; the resistance wire is prone to oxidation and short - circuit phenomena, resulting in a short service life of the heater. Summary of the Utility Model

[0004] Aiming at the above - mentioned defects, the purpose of the utility model is to provide a glass heater to solve the problem of slow heating of existing heaters that mostly use resistance wires as heating elements.

[0005] To achieve this purpose, the utility model adopts the following technical solutions:

[0006] A glass heater includes a body and a heating component;

The heating component is used to generate heat, and the heat generated by the heating component is dissipated to the outside of the body through the heat dissipation holes;

[0008] An air outlet grille and an air inlet grille communicating with the accommodation cavity are respectively provided at the upper and lower ends of the body. The heating component is provided with an air flow channel, and the air outlet grille and the air inlet grille are respectively communicated with the outlet and the inlet of the air flow channel.

[0009] Preferably, the heating component includes two mounting frames. The two mounting frames are detachably installed in the accommodation cavity.

One side of each heating body is respectively clamped in the corresponding mounting groove, and two of the heating bodies respectively cover the adjacent heat dissipation holes.

[0010] Preferably, the number of the heating bodies is two, and the heating bodies are heating glasses.

[0011] Preferably, the heating elements are arranged at intervals, and an air flow channel is formed between adjacent heating elements.

[0012] Preferably, the minimum gap between adjacent heating elements is 10 mm.

[0013] Preferably, heat-insulating glue is bonded between two of the heating elements covering the heat dissipation holes and the body.

[0014] Preferably, the heat-insulating glue is foam glue.

[0015] Preferably, the projected area of the heating element in the front view direction is 30%-80% of the projected area of the body in the front view direction.

[0027] The following will Figures 1 to 3 further illustrate the technical solution of the present utility model in conjunction with the accompanying drawings

[0028] As Figures 1-3 shown, a glass heater includes a body 1 and a heating component 2;

[0029] An accommodation cavity is provided inside the body 1. Heat dissipation holes 11 communicating with the accommodation cavity are respectively provided on two opposite outer side walls of the body 1. The heating component 2 is installed in the accommodation cavity. The heating end of the heating component 2 covers the heat dissipation holes 11. The heating component 2 is used to generate heat, and the heat generated by the heating component 2 is dissipated to the outside of the body 1 through the heat dissipation holes 11;

[0030] Air outlet grilles 12 and air inlet grilles 13 communicating with the accommodation cavity are respectively provided at the upper and lower ends of the body 1. The heating component 2 is provided with an air flow channel 24. The air outlet grilles 12 and the air inlet grilles 13 are respectively communicated with the outlet and the inlet of the air flow channel 24.

[0031] In this solution, the heat generating end of the heat generating component 2 radiates heat to the outside of the body 1. At the same time, air flows upward through the air inlet grille 13, the accommodation cavity, the air flow channel 24 and the air outlet grille 12, and is heated by the heat generating component 2 in the air flow channel 24, forming a convective heat transfer with hot air rising. Heating is achieved simultaneously through two methods: heat radiation and heat convection, reducing the ineffective loss of energy and increasing the heating rate.

[0032] It should be noted that by radiating heat to the outside of the body 1 through the heat generating end of the heat generating component 2, the heater can have a larger heat generating area. Therefore, the thickness of the heater body can be made thinner than that of conventional heaters.

[0033] As Figure 3 shown, the heat generating component 2 includes two mounting frames 21. The two mounting frames 21 are detachably mounted in the accommodation cavity. At least two heating elements 22 are provided between the two mounting frames 21. Mounting grooves 211 are respectively provided on the opposite sides of the two mounting frames 21. One side of each heating element 22 is respectively clamped in the corresponding mounting groove 211. Among them, the two heating elements 22 respectively cover the adjacent heat dissipation holes 11.

[0034] Specifically, the heating element 22 can be fixed through the mounting frame 21, which can facilitate the stable installation of the heating element 22 in the accommodation cavity.

[0035] As Figure 3 shown, the number of the heating elements 22 is two, and the heating elements 22 are heating glasses.

[0036] Specifically, the heating glass adopts advanced electrothermal film technology, which can efficiently convert electrical energy into heat energy, with a high electrothermal conversion rate, thus saving energy. Moreover, the heating glass does not generate open flames during operation, avoiding safety hazards such as fires, and has a longer service life compared to traditional heating elements such as electric heating wires.

[0037] As Figure 3 shown, the adjacent heating elements 22 are arranged at intervals, and the air flow channel 24 is formed between the adjacent heating elements 22.

[0038] As Figure 3 shown, the minimum gap between the adjacent heating elements 22 is 10 mm.

[0039] Specifically, setting the minimum gap between the adjacent heating elements 22 to 10 mm can make the thickness of the heater thinner while not affecting the heat convection effect of the heater.

[0040] As Figure 3As shown, a heat-insulating adhesive 23 is bonded between the two heating elements 22 covering the heat dissipation holes 11 and the machine body 1 .

[0041] Specifically, the heat insulating adhesive 23 can effectively reduce the heat transfer from the heating element 22 to the body 1, thereby preventing the body 1 from overheating and causing burns when the user touches it.

[0042] like Figure 3 As shown, the heat insulating adhesive 23 is foam adhesive.

[0043] Specifically, the foam adhesive has good bonding properties, heat insulation effects and weather resistance, and can increase the service life of the device.

[0044] like Figures 1-2 As shown, the projection area of ​​the heating element 22 in the front view direction is 30%-80% of the projection area of ​​the machine body 1 in the front view direction.

[0045] Specifically, the projection area of ​​the heating element 22 in the front view direction is set to 30%-80% of the projection area of ​​the body 1 in the front view direction, which can ensure that the heater has good heat radiation and heat convection effects.

[0046] like Figure 1 As shown, the two sides of the bottom end of the body 1 are detachably mounted with supporting feet 3.

[0047] Specifically, the heater can be placed on the ground by means of the provided support legs 3, and when necessary, the support legs 3 can be removed to hang the heater on the wall.

[0048] like Figure 3 As shown, a fixing block 25 is provided between adjacent heating elements 22 . The fixing block 25 can be detachably installed in the accommodating cavity. A wire fixing groove 251 is provided on one side of the fixing block 25 facing the heating element 22 .

[0049] Specifically, the power line of the heating element 22 can be stored in the wire fixing groove 251 through the provision of the wire fixing groove 251, thereby reducing safety hazards.

[0050] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
