Description

Electric fireplace with burning ball

The present invention relates to an electric fireplace, and more particularly to an electric fireplace with a burning ball. Background technique

The electric fireplaces of the prior art mostly imitate the structural mode of the traditional fireplace, and are arranged on a certain wall of the room. The light emitted by the electric fireplace imaging light source is dynamically processed by the light processing device to simulate the firewood and charcoal fire of the traditional fireplace on the imaging screen. And images such as flames, to achieve the purpose of simulation. In general, manufacturers of electric fireplaces strive to have a realistic feel of the flames simulated by electric fireplaces in order to achieve high simulation visual effects. A three-dimensional flame simulation electric fireplace is disclosed in the patent document published on Apr. 23, 2008, the disclosure of which is incorporated herein by reference. The simulated charcoal is provided with a translucent imaging screen immediately behind the simulated charcoal, and a second imaging screen is disposed in front of the imaging screen, and the second imaging screen is disposed substantially parallel to the imaging screen. The light generated by the imaging light source passes through the light processing device, and is projected onto the imaging screen to form a primary flame analog image, and part of the light is projected onto the second imaging screen through the imaging screen to form a secondary flame analog image, when the imaging screen and the second imaging screen When a sufficient distance is maintained between them, since the front and rear positions of the flame images of the two are different, a flame visual effect having a depth level can be formed. The structure utilizes the translucent property of the imaging screen to transmit part of the light to the second imaging screen, thereby forming a front and rear two-layer flame simulation image, which has a certain stereoscopic effect, thereby enhancing the realism of the simulated flame. However, the prior art electric fireplace designs the structure around the stereoscopic feeling, authenticity, and the like of the simulated flame, and the result is only different in the simulated flame pattern. The formation of the electric fireplace flame picture is similar, the same situation, resulting in the user's aesthetic fatigue on the electric fireplace flame picture, affecting the development of the electric fireplace industry. Disclosure of invention

The object of the present invention is to provide an electric fireplace with a burning ball with a strange flame and a novel visual effect in order to solve the problem that the flame picture of the existing electric fireplace is similar and different.

The specific technical solution adopted by the present invention to achieve the above technical object is: an electric fireplace with a combustion ball, comprising a casing, an imaging light source, a light processing device and an imaging screen, between the light processing device and the imaging screen The combustion ball is provided with a light transmitting structure, and the ratio of the surface area of the combustion ball to the average area of the spot reflected by the light processing device on the surface of the combustion ball is greater than 20. A light-transmitting structure of the combustion ball is disposed between the light processing device and the imaging screen. When the image light reflected by the light processing device is irradiated onto the spherical structure of the combustion ball, since the surface area of the combustion ball is much larger than the spot area of the imaging light, Under the action of the sphere structure, we can see through the imaging screen that there are several flames that are constantly changing on the spherical surface. These flames seem to be constantly moving away from the sphere and then returning to the sphere and moving along the sphere at the same time. The imaging light that changes according to a certain rule is formed by the structure of the sphere. Although it is impossible for our fireplace to have such a burning flame, this flame has a very novel visual effect. The spherical surface referred to here is a blurred outline of the physical position of the burning ball as seen through the imaging screen. In addition, the term "light spot" as used herein refers to an illuminating area formed by a light reflecting device that reflects light of an imaging light source and is reflected by a certain reflecting surface to a surface of the burning ball at a certain moment. The spot is continuously moving. Different, different reflective surfaces or the same reflective surface can form different sizes of light spots at different times. Although the size of the light spots is different, the light spots formed by the traditional electric fireplace light processing device on the imaging screen are not Large, usually in the range of a few square centimeters. The mean value of the spot area refers to the theoretical average or estimated average value of the spot formed by the light reflected from the reflective part of the electric processing device to the surface of the burning ball during the period of one rotation of the electric fireplace. Next, for most conventional light treatment devices, the diameter of the combustion ball is between 4 cm and 25 cm. In particular, the traditional electric fireplace has a method of setting a simulated carbon block, and sometimes a transparent glass ball is used as a simulated carbon block, but these glass balls are usually small, and their surface area and imaging on the glass ball are irradiated. The spot area of the light is not much different, so the technical effect of the present invention cannot occur under the irradiation of the imaging light.

Preferably, the imaging screen is a blanking imaging screen, and the aspect ratio of the imaging screen is greater than 1 to 3. Since the contour of the spherical structure is displayed on the imaging screen to a certain extent, the ordinary imaging screen affects the viewing effect of the electric fireplace. The imaging screen used in the present invention is a blanking imaging screen, and the imaging screen and the conventional imaging screen are used. The difference is that the blanking effect is better. The structure usually shows that the diffuse reflection structure of the imaging screen is more rough. It can effectively blur the contour of the burning ball, so that what we see on the imaging screen is only the flame displayed on the burning ball. In this way, the flame is integrated with the sphere to form a visual effect of burning the ball.

Preferably, the burning sphere is a transparent or translucent, smooth-looking sphere or ellipsoid. The flame picture displayed by the transparent and smooth structure of the burning ball is relatively clear, while the flame picture displayed by the burning ball of the translucent structure is relatively fuzzy, has a squeaky feeling, and its simulation effect is relatively poor. The use of a smooth, continuous sphere or elliptical sphere ensures that the surface of the burning sphere does not exhibit diffuse reflection, thereby affecting the focus of the light, and does not form an effective active flame pattern. Although a burning sphere with an irregular spherical structure on the surface can simulate a similar flame structure to some extent, irregular changes in the surface of the burning sphere can cause irregularities in the movement of the flame, resulting in The simulated flame approaches the conventional flame and loses its novel visual effect.

Preferably, there are several combustion balls, each of which is independently disposed, and the combustion ball has a single layer structure in the thickness direction of the electric fireplace. The number of burning balls is generally set according to the size of the electric fireplace imaging screen and the size of the burning ball. Usually, several flames can be set. Since the flames of the burning ball can be continuously slid, the independent setting of each burning ball is beneficial. Maximize the dynamic flame of the burning ball.

For electric fireplaces with higher imaging screens, the following structure can also be used: The combustion balls are connected to form a burning string, the length direction of the burning string is consistent with the height direction of the electric fireplace, and the electric fireplace is provided with a plurality of burning balls. The burning string is a single layer structure in the thickness direction of the electric fireplace. For an electric fireplace with a high image screen, if there are too few burning balls, the burning ball will occupy less position on the entire screen surface, thus affecting the viewing effect, and setting independent burning balls at different heights will not only The setting of the burning ball is difficult, and the fixing mechanism of the burning ball easily blocks the imaging light, thereby affecting the simulation effect. The combustion balls are connected to form a combustion ball string, and are arranged in an electric fireplace in the form of a burning ball string, such as a hanging arrangement, which can not only increase the proportion of the combustion ball on the screen surface of the imaging screen, but also enhance the simulation. The effect can also reduce the difficulty of setting the combustion ball, reduce the influence of the fixing mechanism of the burning ball on the simulated flame of the electric fireplace, and also help to simplify the structure and reduce the cost. The so-called single-layer structure means that the electric fireplace only has one burning ball in the thickness direction where the burning ball is located. This is to ensure the strange effect of the flame simulated by the electric fireplace, but the burning ball and the imaging screen at different positions or The distance between the light processing devices may be the same or different, and the combustion balls at different positions are not required to be disposed on the same straight line.

The burning ball can be of the same size or elliptical ball structure, or a mixed structure of the same size spherical ball and the same size elliptical ball. The shape and size of the burning ball are the same, It is convenient to produce and helps to reduce production costs, but the simulated flame pattern is relatively simple. In addition, the combustion ball can also be a spherical or elliptical ball structure of different sizes, or a mixed structure of spheres of different sizes and elliptical spheres of different sizes. The use of different shapes and sizes of combustion balls can enrich the flame pattern simulated by the electric fireplace. The disadvantage is that the installation is complicated, which is not conducive to tissue production, and the production cost is relatively high.

For an electric fireplace using a burning string, the burning balls on the burning string are arranged in a straight line or a curve, and the burning balls on the burning string are arranged continuously or at intervals. The different arrangement of the burning balls on the burning string can make the electric fireplace have different flame simulation effects, avoiding the similarity of the electric fireplace flame pattern, so as to meet the viewing requirements of different users.

The combustion string may also be provided with a combustion column of transparent or translucent structure. The combustion column is a columnar structure with a circular or elliptical cross section, and the length direction of the combustion column is consistent with the extending direction of the combustion string, the combustion column and the combustion Ball spacing setting. The columnar structure of the combustion column and the flame of the spherical structure burning ball have different visual effects, which can also enrich the flame pattern of the electric fireplace.

Preferably, the light processing device is a rotating shaft driven by the motor and a reflective strip disposed on the rotating shaft or a sleeve type light processing device including a core shaft, a rotating drum and a reflective strip disposed on the rotating drum. The light processing devices of the two preferred structures all have the characteristics of good flame simulating effect, simple setting and low cost. In addition, the light processing device can also adopt a reflective structure of a floating structure, the reflective curtain comprising a plurality of spaced arrays and having A flexible strip-shaped reflector of wavy structure. The average area of the spot formed by such a light processing device after reflecting the imaging source is usually 1 to 5 square centimeters. In addition, for an electric fireplace with a low image height, the light processing device can be set by a conventional setting method, that is, the light processing device is disposed at a position lower than the rear side or the rear side of the combustion ball, and the electric fireplace is higher for the image forming screen. When multiple layers of combustion balls are placed in the height direction of the electric fireplace (if In the case of a burning ball string structure, a multi-layered light processing device can be used. In this case, the imaging light source of the electric fireplace can also be arranged differently from the conventional structure, that is, in addition to providing an imaging light source at the bottom of the electric fireplace, It is also possible to provide an imaging light source on both sides or at the top of the electric fireplace, or an imaging light source having an illumination directivity, which has achieved the purpose of illuminating the light processing device at a relatively distant location.

The invention has the beneficial effects that: the utility model effectively solves the problem that the flame picture existing in the existing electric fireplace is similar and identical, and the same is the same. The electric fireplace of the invention has a strange flame and a novel visual effect, giving a refreshing feeling, and is a traditional electric The major innovation of the fireplace flame simulation technology has opened up a new field of electric fireplace flame simulation with good economic benefits.
