Description

Convection heater

Technical Field

The utility model relates to a heating installation technical field, concretely relates to convection heater.

Background

The convection heater is widely used for mobile heating of houses, offices, hotels, markets, hospitals, schools, train carriages and the like, and heating equipment of various civil and public buildings such as simple movable houses and the like. The existing convection warmer structure generally comprises a housing, wherein an air outlet is arranged on the housing, an air inlet is arranged below the housing, air around an electric heating tube is heated and ascended after being electrified, the air flows out of the air outlet, and cold air around the electric heating tube enters and is supplemented from the air inlet. The above-mentioned processes are repeated to obtain the heating effect, and can raise indoor temp.

But current convection current room heater still has the defect, and its inside does not have solitary wind channel or only single fore-and-aft direction wind channel heat conduction mostly, has the gas outlet of a direction only, and steam can only move along the gas outlet of unilateral, causes the one side that lies in this gas outlet just can experience steam, and other directions at this room heater then can not experience steam, and the heating direction is limited, can't satisfy the heating demand when the heating number is more. And because the hot gas only flows out from one air outlet, the hot gas flow-out speed is slow, and the heating efficiency is not high.

Therefore, a convection heater for heating in multiple directions is urgently needed to meet the requirement of heating for multiple people and improve the heating efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model provides a convection heater to solve the problem that the convection heater can't be multi-directionally heated among the prior art.

In order to achieve the above purpose, the basic scheme of the utility model is as follows: the utility model provides a convection heater, includes the casing and sets up in the top cap at casing top, the top cap with the casing surrounds formation chamber that generates heat, generate heat the intracavity and be provided with heat-generating body subassembly, the air intake has been seted up to the casing bottom, first air outlet has all been seted up on casing side upper portion, arbitrary first air outlet department all is provided with the grid, the second air outlet has been seted up on the top cap, second air outlet below is equipped with the guide plate, first air outlet with it has the wind channel to communicate respectively between the chamber to generate heat, the casing surface is provided with control panel, the electricity is connected between control panel and the heat-generating body subassembly.

The working principle of the scheme is as follows: the control panel controls the heating element assembly to generate heat, air in the heating cavity is heated and rises to form hot air flow, and the guide plate blocks the circulation of the second air outlet, so that part of hot air flow changes the flowing direction and flows out of the first air outlet through air duct guide, and the other part of hot air flow bypasses the guide plate and flows out of the second air outlet, so that the warmer can radiate heat in multiple directions around and at the top of the shell.

Compared with the prior art, the technical scheme has the advantages that: 1. through the arrangement of the guide plate and the independent air channel, hot air can flow out from the top and the side of the heater, so that the technical effect of multidirectional heating is achieved, compared with the existing heater which can only heat in a single direction, the quantity of air outlets is increased, the circulation speed of the hot air is increased, the heating efficiency is improved, the heating range is greatly increased, and the requirement of heating by multiple people is met; 2. on the basis of a common warmer, a first air outlet and an air duct are additionally arranged, so that the multidirectional warming effect is achieved, the structure is simple and compact, and the manufacturing cost is low; 3. through increasing air outlet quantity, enlarged the air-out area for the air convection effect is more obvious, and the heating effect is better.

Furthermore, a groove is formed in the upper surface of the guide plate, and a connecting rod is connected between the guide plate and the air channel. The arrangement of the groove increases the space between the second air outlet and the guide plate, and the efficiency of hot air flowing out from the second air outlet is improved.

Further, the heat-generating body subassembly includes convection type heat-generating body and heat-generating body support, the heat-generating body support is located between air intake and the first air outlet the intracavity that generates heat, install side by side on the heat-generating body support according to certain horizontal interval to the convection type heat-generating body. Through setting up the convection type heat-generating body, utilize the cold air heavy and descend, the principle that the hot-air is light and rise, the heat that makes the frame that generates heat produce distributes away voluntarily, forms sustainable convection circulation, does not need the fan to force to blow out the heat.

Further, the casing includes the bottom plate of level setting and the left side board, right side board, backshell and the preceding shell of vertical setting, left side board, right side board, backshell and preceding shell end to end encircle locate the bottom plate upper surface.

Furthermore, a plurality of first heat dissipation holes are formed in the left side plate, the right side plate and the rear shell respectively, and a plurality of second heat dissipation holes are formed in the top cover. The first heat dissipation hole and the second heat dissipation hole are formed, so that heat in the warmer can be dissipated in time, the temperature in the shell is kept relatively stable, and the device is prevented from being damaged due to overhigh temperature.

Further, a base is arranged below the bottom plate.
