Detailed Description

In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, without conflict, the embodiments of the present invention and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced otherwise than as described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1, 2 and 3, a first embodiment of the present invention proposes a warmer, comprising: the housing 102, the bracket 104, the heat generating component 108, and the blower 110.

As shown in fig. 2 and 3, the bracket 104 is disposed in the housing 102, and the bracket 104 includes a blowing chamber 126 and a blowing port 106 communicating with the blowing chamber 126, and the blowing port 106 communicates with a space between the bracket 104 and the housing 102. The heat generating element 108 is disposed within the housing 102 and is operable to provide heat to the interior of the housing 102. Specifically, the heating element 108 supplies heat to the space between the bracket 104 and the cover 102, and at least part of the generated heat is radiated to the outside of the cover 102, so as to realize the heating function of the warmer.

In addition, as shown in fig. 2 and 3, the air flow generated by the fan 110 during operation may enter the space between the bracket 104 and the cover 102 through the air supply chamber 126 and the air supply port 106, and be discharged after being uniformly mixed with the hot air in the space between the bracket 104 and the cover 102.

In particular, since the heat generating member 108 continuously supplies heat to the space between the bracket 104 and the cover 102, and the heat is directly radiated to the outside of the cover 102, the temperature near the cover 102 is too high, which has a safety hazard. Therefore, in this embodiment, the air supply cavity 126 is disposed on the bracket 104 in the cover 102, and the air supply port 106 of the air supply cavity 126 is ensured to be communicated with the space between the bracket 104 and the cover 102, and the air supply port 106 is ensured to face the inner wall of the cover 102.

The air flow driven by the fan 110 is not heated to be cool air, so that the cool air is mixed with the heated hot air between the bracket 104 and the cover 102. The cool air and the hot air exchange heat continuously in the space between the bracket 104 and the cover 102, and are discharged out of the cover 102 after being uniformly mixed.

In this way, the temperature of the air blown out from the cover body 102 can be ensured to be proper, the intensity of the heat radiation is reduced, the temperature of the heat radiation is reduced, a user can achieve a more comfortable heating effect, and meanwhile, potential safety hazards are avoided.

In addition, during the heat release from the heat-generating component 108, the hot air may continuously rise within the enclosure 102 and collect in the top region of the enclosure 102. The invention drives the external cold air to the air supply cavity 126 and the inside of the cover 102 through the fan 110, thereby further reducing the temperature inside the warmer. Therefore, the technical problem of overhigh temperature rise of the top of the cover body in the related technology is solved, and the use safety of the warmer is further improved.

Therefore, as shown in fig. 2 and 3, the warmer provided in this embodiment can mix and discharge cold air and hot air, so as to greatly reduce the temperature of air blown out by the cover 102, avoid the excessive temperature near the cover 102, and is suitable for heating a user in a short distance, and simultaneously, under the action of the fan 110, the cold air and the hot air are mixed and discharged, so that remote heating can be realized. And moreover, a user can achieve a more comfortable heating effect, and meanwhile, the use safety of the warmer is improved.

Wherein the heat pipe is bent and disposed in the cover 102, such that the shape of the heat pipe matches the annular space between the bracket 104 and the cover 102. Thus, in the using process of the warmer, the heating tube uniformly releases heat in the annular space between the bracket 104 and the cover body 102, and the heat is circularly radiated to the surrounding, so that the effect of uniform warming is realized.

In addition, as shown in fig. 2 and 3, a through hole is provided in the middle of the annular grill, and the heating pipe surrounds the circumference of the air supply chamber 126. In this way, in the working process of the warmer, the heat generated by the warmer can be released into the space where the warmer is located in a ring shape, and the uniformity of heat radiation can be further improved due to the arrangement of the through hole in the middle of the cover body 102.

In this embodiment, further, as shown in fig. 2 and 3, the grill 114 is the heat generating side of the warmer and generally faces the user during use of the warmer.

Accordingly, the present invention provides a safe distance between heat generating element 108 and grill 114. In this way, in the using process of the warmer, a certain distance between the heating element 108 and the user can be ensured, and even if the user is very close to the grid 114, a certain distance between the heating element 108 and the user can be ensured, so that the using safety of the warmer is further improved.

The sixth embodiment of the present invention provides a warmer, further on the basis of the first embodiment:

the warmer also includes controls (not shown) and can be used to regulate the rotational speed of the blower 110 and thus the amount of air entering the plenum 126 and the interior of the enclosure 102.

During use of the warmer, when the user wants the radiant temperature of the warmer to be a little higher, the control controls the rotational speed of the fan 110 to decrease. At this time, the cool air entering the blower chamber 126 and the housing 102 is reduced. The heat generating member 108 increases the temperature of heat radiation to the outside.

During use of the warmer, when the user wants the radiant temperature of the warmer to be somewhat lower, the control controls the fan 110 to increase in rotational speed. At this time, the amount of cool air entering the blower chamber 126 and the housing 102 increases. The heat generating member 108 is lowered in temperature against external heat radiation.

Further, as shown in fig. 1 and 2, the warmer further includes a base 122 and a body 124. The body 124 is connected between the cover 102 and the seat, the body 124 and the cover 102 are stably placed through the seat 122, and the cover 102 is supported to a certain height through the body 124.

Further, the fan 110 may be disposed inside the housing 102, and the fan 110 may directly blow air into the air-blowing chamber 126. In this way, the overall structural size of the warmer can be reduced, and the air flow generated by the fan 110 can enter the space between the bracket 104 and the cover 102 through the air supply cavity 126 and the air supply port, and is discharged after being uniformly mixed with the hot air in the space between the bracket 104 and the cover 102.

Further, the fan 110 may be disposed outside the housing 102, and the fan 110 may directly blow air into the air blowing chamber 126. In this way, the structural requirement on the cover 102 can be reduced, and the air flow generated by the fan 110 can enter the space between the bracket 104 and the cover 102 through the air supply cavity 126 and the air supply port, and is discharged after being uniformly mixed with the hot air in the space between the bracket 104 and the cover 102.

The air blowing chamber 126 is located inside the ring holder, and the air flows toward the heat generating element 108 side in the air blowing chamber 126. And, the sectional area of the annular bracket gradually decreases in the direction from the fan 110 to the heating element 108, so that the air flow discharged from the air supply outlet 106 has a certain speed, and the disturbance effect of the air flow between the cover body 102 and the bracket 104 is ensured. In addition, the fan 110 and the heating element 108 are arranged on the bracket 104, and a certain supporting effect can be achieved for the fan 110 and the heating element 108 through the bracket 104. In addition, the fan 110 is arranged in the air supply cavity 126, the heating element 108 is arranged outside the air supply cavity 126, and heat generated by the heating element 108 is prevented from radiating to the fan 110, so that the service life of the fan 110 is ensured
