BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an electric fireplace, and more particularly to an intelligent electric fireplace.

2. Description of the Prior Art

In modern society, electric fireplaces are developed rapidly instead of traditional fireplaces. While people enjoy the convenience brought by electric fireplaces, more modern needs are required. For example, traditional electric fireplaces usually only have the function of heating, providing a single function. Environmentally friendly electric fireplaces are developed accordingly, which use ultraviolet germicidal lamps to disinfect the air before heating, and the structure is relatively complicated. Moreover, the ultraviolet germicidal lamp is used all the time, which consumes a lot of electricity, and the ultraviolet germicidal lamp needs to be replaced frequently.

Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve this problem.

SUMMARY OF THE INVENTION

In view of the shortcomings of the prior art, the primary object of the present invention is to provide an intelligent electric fireplace. By providing an air quality sensing module and an ultraviolet germicidal lamp in the electric fireplace, the ultraviolet germicidal lamp can be turned on/off according to the air quality condition fed back by the air quality sensing module to reduce a waste caused by the ultraviolet germicidal lamp that is still used when the air quality condition meets the standard. It is more energy-saving and environmentally friendly, and it is more intelligent.

In order to achieve the above object, the present invention adopts the following technical solutions:

An intelligent electric fireplace comprises a housing. A simulated charcoal and a first light-emitting device are provided in the housing. The first light-emitting device is configured to emit light toward the simulated charcoal to form a burning effect of the simulated charcoal.

The housing includes an air inlet, an air outlet, a heating device, a control device, an air quality sensing module, and an ultraviolet germicidal lamp. The first light-emitting device, the heating device, the air quality sensor module and the ultraviolet germicidal lamp are electrically connected to the control device, respectively. The ultraviolet germicidal lamp is turned on/off according to an air quality condition fed back by the air quality sensing module.

Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be known from the above technical solutions:

1. By providing the air quality sensing module and the ultraviolet germicidal lamp in the electric fireplace, the ultraviolet germicidal lamp can be turned on/off according to the air quality condition fed back by the air quality sensing module to reduce a waste caused by the ultraviolet germicidal lamp that is still used when the air quality condition meets the standard. It is more energy-saving and environmentally friendly, and it is more intelligent.

2. It can realize automatic air quality detection, automatically turn on/off the ultraviolet germicidal lamp, and use the control device to immediately turn on the ultraviolet germicidal lamp for disinfection according to the air quality condition fed back by the air quality sensing module. When the air quality condition fed back by the air quality sensing module meets the standard, the control device controls the ultraviolet germicidal lamp to stop working. Preferably, the control device controls the light-emitting state of the first light-emitting device to be changed according to the air quality condition fed back by the air quality sensing module. The user can judge the current air quality condition intuitively through the burning state of the simulated charcoal, so the prompt effect is good.

3. The structural design of the whole electric fireplace is very clever.

The ultraviolet germicidal lamp is mounted to the underside of the middle plate. Through the accommodation space of the electric fireplace itself, the ambient air is in communication with the accommodation space through the meshed panel. The air flowing into the accommodation space is disinfected by the ultraviolet germicidal lamp. Generally, the front of the electric fireplace has a larger area, so the indoor air is in good communication with the accommodation space, and the ultraviolet germicidal lamp has a better disinfection effect.

The air quality sensing module is installed on the left, right or back of the upper space of the electric fireplace, keeping away from the air outlet of the electric fireplace, so that the detection of air quality is closer to the real situation of indoor air. Besides, it is more convenient to install the air quality sensing module on the left or right side of the upper space.

Furthermore, the middle plate extends obliquely upward from back to front, so that the light emitted by the ultraviolet germicidal lamp is irradiated outward toward the front side of the accommodation space, thereby further improving the disinfection effect of the ultraviolet germicidal lamp.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1 through FIG. 11, there is shown a specific structure of an embodiment of the present invention.

An intelligent electric fireplace comprises a housing. A simulated charcoal 1 and a first light-emitting device 2 are provided in the housing. The first light-emitting device 2 is configured to emit light toward the simulated charcoal 1 to form a burning effect of the simulated charcoal 1. The first light-emitting device 2 is located below the simulated charcoal 1. A reflector 3 and a second light-emitting device 4 emitting light toward the reflector 3 are provided behind the first light-emitting device 2. The reflector 3 is equipped with a rotating motor 22 for controlling rotation of the reflector 3. The second light-emitting device 4 is mainly used for imaging the flame.

The housing includes an air inlet 20′, an air outlet 20, a heating device 21, a control device 5, an air quality sensing module 6, and an ultraviolet germicidal lamp 7. The first light-emitting device 2, the heating device 21, the air quality sensor module 6 and the ultraviolet germicidal lamp 7 are electrically connected to the control device 5, respectively. The ultraviolet germicidal lamp 7 is turned on/off according to the air quality condition fed back by the air quality sensing module 6.

The control device 5 controls the light-emitting state of the first light-emitting device 2 to be changed according to the air quality condition fed back by the air quality sensing module 6. The change of the light-emitting state means that the first light-emitting device 2 is in the first light-emitting state when the air quality condition fed back by the air quality sensing module 6 meets the standard; the first light-emitting device 2 is in the second light-emitting state when the air quality condition fed back by the air quality sensing module 6 does not meet the standard. The first light-emitting state and the second light-emitting state are visually different. For example, the first light-emitting state refers to static light emission, and the second light-emitting state refers to blinking light emission; or, the first light-emitting state and the second light-emitting state refer to light emission in different colors.

As shown in FIG. 11, the control device 5 includes an MCU (microprogrammed control unit). The air quality sensing module 6, the first light-emitting device 2 and the second light-emitting device 4 are electrically connected to the MCU, respectively. The MCU is connected to a power supply driving module 18 through a relay or MOS transistor drive 17, and further connected to the ultraviolet germicidal lamp 7. The power supply input end of the electric fireplace is connected to the air quality sensing module 6 and the MCU through a power supply voltage stabilizing module 19, respectively.

In this embodiment, by providing the air quality sensing module 6 and the ultraviolet germicidal lamp 7 in the electric fireplace, the control device turns on the ultraviolet germicidal lamp 7 for disinfection in a real-time manner according to the air quality condition fed back by the air quality sensing module 6. After the air quality condition fed back by the air quality sensing module 6 meets the standard, the control device controls the ultraviolet germicidal lamp 7 to stop working. This can effectively reduce the waste of energy when the air quality meets the standard and the ultraviolet germicidal lamp 7 is still in use.

The present invention may further comprise a switch 71 for manually controlling the ultraviolet germicidal lamp 7 to be turned on/off. When the light-emitting state of the first light-emitting device 2 shows that the air quality condition does not meet the standard, the user manually controls the switch 71 to turn on the ultraviolet germicidal lamp 7 for disinfection. Of course, both automatic control and manual control can be provided. For safety, the present invention may further comprise an infrared sensor 72 for detecting whether there is a person in front of the housing. The infrared sensor 72 is connected to the control device 5. When the infrared sensor 72 detects a person in front of the housing, the control device 5 controls the ultraviolet germicidal lamp 7 to stop working, so as to ensure personal safety.
