Description

Technical Field

[0001] The utility model relates to the technical field of electric heating equipment, in particular to an electric fireplace. Background Art

[0002] Currently, electric fireplaces are electric heating devices embedded in walls. Most electric fireplaces only have one set of electric heating devices, which limits the maximum heating power of the electric fireplace and makes it difficult to adjust the heating power of the electric fireplace.

[0003] At the same time, electric fireplaces are limited by their installation methods. The air inlet and outlet of the electric fireplace are both set on the front of the electric fireplace. The electric heating device can be seen through the air inlet and outlet, which makes it easy for foreign objects to enter the air duct and touch the electric heating device. For example, if water is poured, liquid can easily enter the air duct and touch the electric heating device, thereby generating steam and causing accidental injury. Utility Model Content

[0004] The purpose of the utility model is to provide an electric fireplace with multiple electric heating devices.

[0005] The purpose of this utility model is achieved like this.

[0006] An electric fireplace includes a shell, two air ducts are arranged in the shell, each air duct has a first opening and a second opening connected to the outside world on the front of the shell, a fan and an electric heating device are arranged in the air duct, and the two air ducts are connected.

[0007] When the two electric heating devices work at the same time, the electric heating devices heat the airflow in the two air ducts respectively, and the fan sends the airflow out of the shell from the corresponding second opening, so that the corresponding first opening draws the external airflow into the air duct.

[0008] When only one electric heating device is working, the electric heating device heats the airflow in the corresponding air duct respectively, and the fan sends the airflow out of the shell from the corresponding second opening, so that the corresponding first opening and the first opening and second opening of the other air duct draw the external airflow into this air duct.

[0014] Furthermore, the air duct is respectively formed with an air passing section inclined forward and downward corresponding to the first opening and the second opening.

[0015] The mesh plate blocks foreign objects larger than the aperture from entering the air duct, and the air passage section makes it more difficult for foreign objects to enter the air duct, preventing water droplets such as splashing water from entering the air duct.

The four duct sections respectively correspond to the corresponding first opening and the second opening, and the four duct sections are connected through the installation cavity behind the upper duct shell and the lower duct shell.

[0021] The two air ducts are easy to form.

[0022] Furthermore, the fan and the electric heating device are arranged behind the mesh plate.

[0023] The fan and electric heating device cannot be seen from the front, realizing a hidden design of the fan and electric heating device.

[0024] Furthermore, the front portions of the upper shell and the lower shell of the air duct are both arranged to be tilted forward and downward, so that the front portion of the air duct section forms an air flow section tilted forward and downward.

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0038] Example 1, see Figure 1-8 As shown, an electric fireplace includes a housing 1 having a mounting cavity 2. Within the mounting cavity 2 are an upper air duct housing 3, a lower air duct housing 4, a partition 5, and a mesh panel 6. The upper air duct housing 3 and the lower air duct housing 4 are arranged in a long strip, with the upper air duct housing 3 positioned above the lower air duct housing 4. The cavity between the upper air duct housing 3 and the lower air duct housing 4 is divided into four air duct sections by the partition 5. A mesh panel 6 is provided in each air duct section. Two groups of two adjacent air duct sections form a single air duct, resulting in two air ducts within the housing 1.

[0039] Each air duct is provided with a first opening 11 and a second opening 12 on the front of the housing 1, which are connected to the outside world. The four air duct sections are each connected to the corresponding first opening 11 and second opening 12. The four air duct sections are connected through the mounting cavity 2 behind the upper air duct shell 3 and the lower air duct shell 4, that is, the two air ducts are connected. Preferably, the first openings 11 and the second openings 12 of the two air ducts are arranged symmetrically, and the second openings 12 of the two air ducts are arranged adjacent to each other. The two first openings 11 and the two second openings 12 are arranged in a row. Specifically, the two first openings 11 and the two second openings 12 are arranged in a straight line.

[0040] A fan 7 and an electric heating device 8 are provided within the air duct. Specifically, the fan 7 and the electric heating device 8 are located behind the mesh plate 6. The air outlet of the fan 7 faces the second opening 12, and the electric heating device 8 is located at the air inlet of the fan 7. The fan 7 and the electric heating device 8 are both conventional technologies and will not be described in detail in this embodiment.

[0041] In this embodiment, the front portions of the upper and lower duct shells 3 and 4 are tilted forward and downward, forming a forward and downward tilted airflow section 9 at the front portion of the duct. That is, the airflow section 9 is tilted forward and downward, corresponding to the first and second openings 11 and 12. The mesh panel 6 is installed in the airflow section 9, and the highest point of the first and second openings 11 and 12 is lower than the lowest point of the mesh panel 6. Figure 7 As shown by the middle dotted line LINE1, preferably, the wind section 9 has an inclination angle of 45°.

[0042] The housing 1 is provided with a support plate 13 for supporting the rear portion of the air duct lower shell 4 so that the rear portion of the air duct section is arranged horizontally.

[0043] The top plate 14 of the housing 1 is provided with an air inlet 15 , which is connected to the installation cavity 2 , and the air inlet 15 supplements the air flow of the air duct.

[0044] A control device is also provided in the housing 1 . The control device is electrically connected to the electric heating device 8 and the fan 7 , respectively, and controls the switches of the electric heating device 8 and the fan 7 .

[0045] The operating principle is that when two electric heating devices 8 are operating simultaneously, they heat the air in the two air ducts respectively. Fan 7 then delivers the air out of housing 1 through the corresponding second opening 12, allowing the corresponding first opening 11 to draw the outside air into the air duct. At this point, the electric fireplace operates at maximum power, rapidly raising the ambient temperature.

[0046] When only one electric heating device 8 is operating, it heats the airflow within the corresponding air duct. Fan 7 directs the airflow out of housing 1 through the corresponding second opening 12, allowing the corresponding first opening 11 and the first and second openings 11 and 12 of the other air duct (limited by the electric heating device 8 and fan 7 in this air duct, resulting in a lower airflow) to draw in external airflow into this air duct. At this point, the system operates at half power, with a high airflow rate, which helps maintain the ambient temperature.
