Description

Technical Field

[0001] The invention belongs to the technical field of electric fireplaces, and in particular relates to a temperature control device for an electric fireplace and a temperature control method thereof. Background Art

[0002] An electric fireplace is a device that converts electrical energy into thermal energy. It uses modern acoustic and optical principles to simulate the flame effect of a traditional real fire fireplace, so it is also called a simulated fireplace or simulated flame fireplace. Its temperature control device is an intelligent system that integrates multiple sensors, controllers and actuators. The core function of this system is to accurately sense the indoor temperature and automatically adjust the power output of the heating element to maintain a preset comfortable temperature range.

[0003] When the electric fireplace is working, the temperature control device will activate the heating element for heating. At the same time, the built-in fan system will also start working to evenly blow the heated air throughout the room, thereby increasing the room temperature. If you need to lower the temperature of the electric fireplace, just cut off the power supply of the heating element.

[0004] Since heating elements are usually made of materials with good thermal insulation properties such as ceramics, they absorb and store a large amount of heat energy during the heating process. When the power is cut off, these materials will slowly release the stored heat, causing the surface of the element to remain at a high temperature for a period of time, thereby affecting the cooling efficiency of the electric fireplace.

[0016] A temperature control method for a temperature control device of an electric fireplace, comprising the following steps:

[0017] S1: When the electric fireplace needs to be cooled down, the fan system and the motor are started by the PLC. When the fan system is started, the outside air enters the air inlet, and the gas flows from the air inlet to one side of the air outlet. The motor is started to rotate the first rotating shaft by 90 degrees. The rotation of the first rotating shaft drives the rotation of the mounting seat. The rotation of the mounting seat drives the rotation of the heating element, so that the position of the heating element is parallel to the wind direction.

[0018] S2: When the first rotating shaft rotates, the second rotating shaft is driven to rotate through the first pulley group, the rotation of the second rotating shaft drives the rotation of the second gear, the rotation of the second gear drives the rotation of the third gear, the rotation of the third gear drives the rotation of the second winding roller, so that the second winding roller rotates to reel in the pull rope, and pulls the limit plate to move outward, the movement of the limit plate drives the heat insulation cloth to unwind on the outer wall of the first winding roller, so that the heat insulation cloth covers one side of the heating element to insulate it;

[0019] S3: When the first rotating shaft rotates, the third rotating shaft of the transmission belt of the second pulley group rotates, the rotation of the third rotating shaft drives the rotation of the first bevel gear, the rotation of the first bevel gear drives the rotation of the second bevel gear, the rotation of the second bevel gear drives the rotation of the threaded rod, the rotation of the threaded rod drives the slider to slide inside the device body, the movement of the slider drives the movement of the fourth rotating shaft, so that the cleaning roller moves on the side wall of the air outlet to absorb dust and ensure the temperature control effect of the device.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The present invention sets a rotating assembly. When the electric fireplace needs to be cooled, the PLC controls the motor to drive the first rotating shaft to rotate ninety degrees. The rotation of the first rotating shaft drives the rotation of the mounting seat. The rotation of the mounting seat drives the rotation of the heating element, so that the position of the heating element is parallel to the wind direction, reducing the contact area and contact time between the wind and the heating element, thereby accelerating the cooling of the electric fireplace and improving the temperature control effect of the device.

The rotation of the third gear drives the rotation of the second winding roller. The second winding roller rotates to reel in the pull rope, so that the pull rope pulls the limit plate to move outward. The movement of the limit plate drives the heat insulation cloth to unwind on the outer wall of the first winding roller, so that the heat insulation cloth covers one side of the heating element to insulate it and minimize the contact between wind and the heating element, so that the electric fireplace can be cooled quickly and the temperature control effect of the device can be improved.

The rotation of the mounting seat 6 drives the rotation of the heating element 5, so that the position of the heating element 5 is parallel to the wind direction, reducing the contact area and contact time between the wind and the heating element 5, thereby accelerating the cooling of the electric fireplace and improving the temperature control effect of the device.

[0036] like Figures 1 to 7 As shown, two heating elements 5 are provided.

[0037] Two heating elements 5 are staggeredly arranged inside the device body 1;

[0038] When it is necessary to control the temperature of the electric fireplace, the fan system 3 is driven to allow external air to enter the air inlet 2, and the gas flows from the air inlet 2 to one side of the air outlet 4, while contacting the heating elements 5. The two heating elements 5 heat the gas, thereby improving the heating efficiency of the electric fireplace.

[0039] like Figures 1 to 7 As shown, a first gear 10 is fixedly mounted on one end of the two first rotating shafts 7 , a rack plate 11 is meshedly connected to one side of the two first gears 10 , and the two rack plates 11 are fixedly connected via a connecting plate 12 .

The movement of the rack plate 11 drives the other rack plate 11 to move synchronously through the connecting plate 12, so that the two heating elements 5 rotate at the same time.

[0041] like Figures 1 to 7 As shown, the heat insulation assembly includes a heat insulation cloth 13 arranged inside the device body 1, the heat insulation cloth 13 is installed on the outer wall of the first winding roller 14, the first winding roller 14 is rotatably installed inside the device body 1, one end of the heat insulation cloth 13 is fixedly connected to the limiting plate 16, the side wall of the limiting plate 16 is fixedly connected with a pull rope 17, the end of the pull rope 17 away from the limiting plate 16 is installed on the outer wall of the second winding roller 18, the second winding roller 18 is rotatably installed inside the device body 1, one end of the second winding roller 18 is fixedly connected to the third gear 20, one side of the third gear 20 is meshed with the second gear 19, the second rotating shaft 21 is fixedly installed inside the second gear 19, the second rotating shaft 21 is arranged on one side of the first rotating shaft 7, and the second rotating shaft 21 is connected to the first rotating shaft 7 through a first pulley set 22.

[0049] like Figures 1 to 7 As shown, the slider 28 is rotationally connected to the fourth rotation axis 29 .

[0050] When the protrusion 9 on the outer wall of the cleaning roller 30 contacts the side wall of the air outlet 4 , the roller 30 can rotate due to the friction between the two, thereby improving the dust cleaning effect on the air outlet 4 .
