Description
Technical field the utility model relates to a kind of warmer, the box heating of particularly a kind of cover type.
The box warmer of background technology cover type is a kind of being used at home or the heating installation of office space, it comprises the open type casing of being made by timber, in casing, be provided with by the built on stilts metal pedal of underframe, metal pedal and bottom half form airtight heating space, be glued with several heaters on the lower surface of metal pedal and form heating plate, the metal pedal surface covers one deck carpet or flexible web, the conduction of heat of dependence metal pedal is used for heating with the air heat in space, casing middle and upper part, need heating person to be sitting on sofa or the seat, double-legged sole is stepped on the carpet that steps down in above the metal pedal and is warmed oneself.For avoiding thermal loss, heating person hides the overcover of glazing felt one class toward the contact meeting on leg, and overcover and main heating board and casing upper cavity form the heating space that has certain heat insulation effect and be enclosed in the whole lower part of the body of heating person.For guaranteeing safety, the heating case is provided with automatic constant-temperature control and adjusting device, both can realize thermostatic control, also the heating temperature can be set according to heating person's individual difference, PTC heater element, MCH ceramic heating plate or other similar heater elements that its heater is also often safe to use, the maximum temperature of heater all is lower than the burning-point of timber or blended carpet etc. usually.For improving firing rate, on the madial wall of casing, be provided with auxiliary heating board.Be in contact with it and near air in the upper surface heating service space that existing heating case is the dependence heating board, after the air of heating rises, cold air descends to replenishing and realizes cold and hot air exchange, thereby the space of will warming oneself is heated gradually and is reached temperature required, like this, because the heat radiation of the lower surface of heating board is not rationally utilized, so there is the heating deficiency that the space temperature rise is slow, the thermal efficiency is low; Simultaneously, owing to be subjected to the structural limitations of warmer, the temperature probe of the temperature sensor of thermostatically-controlled equipment can only be located in the closed cavity of heating cabinet bottom, and the temperature in this cavity was both inequality with the temperature in the heating space, there is not direct corresponding relation yet, rely on its temperature of controlling warmer, exist temperature control inaccurate, the purpose of temperature constant in the space of can not effectively realizing warming oneself.
In addition, existing warmer heater directly is close to the back side of main heating board or auxiliary heating board, owing to be a plurality of being distributed on the heating board, the area of single heater is less, the regional temperature that closes on heater is higher, and lower away from the regional temperature of heater, therefore, the temperature distributing disproportionation on the heating board is even, during heating, touch the zone of closing on heater and feel boiling hotter, or feel colder away from the zone of heater, the comfort of heating is relatively poor.For this reason, so need existing warmer is further improved.
The summary of the invention the purpose of this utility model is exactly at the deficiencies in the prior art, provides that a kind of temperature rise is fast, the thermal efficiency is high, the box warmer of the cover type of temperature precise control.
For achieving the above object, the utility model adopts following technical scheme:
The box warmer of a kind of cover type, the open type casing, the control device that comprise the pentahedron shape, be provided with the main heating board that is fixedly connected on the frame structure underframe in the casing, be fixedly connected on the auxiliary heating board on the wall box, main heating board and auxiliary heating board are formed with bottom cavity and sidepiece cavity with casing respectively, the back side of main heating board and auxiliary heating board is respectively equipped with a plurality of heating sheets, described main heating board is provided with several through holes, and through hole is communicated with bottom cavity with the upper space of casing; Described auxiliary heating board only is located on the madial wall of casing, on the madial wall in opposite directions of the auxiliary heating board of casing connection, be provided with scavenge duct, the inlet end of scavenge duct is positioned at main heating board top, the inlet end oral area of scavenge duct is fixedly connected with protective plate, the protective plate outer profile size is slightly larger than the cross sectional dimensions of scavenge duct inlet end oral area, protective plate is provided with the air admission hole that runs through its plate body thickness, and the other end of scavenge duct is communicated with bottom cavity.
After adopting above scheme, the temperature control detecting head of control device is installed in the bottom cavity, when using the box warmer of this cover type to warm oneself, heating person is sitting in the sidewall that is provided with scavenge duct on sofa or the seat towards casing, sole step on the main heating board or place mat on the carpet on the main heating board, hide a felting overcover at shank, and make the common heating space that forms basic sealing of overcover and casing top and heating person.Behind main heating board heating power, air in the bottom cavity is heated by main heating board lower surface, air after being heated rises to the heating space from the through hole on the main heating board, and with directly be used to after hot-air that through hole flows into mixes to warm oneself or improve air themperature in the space of warming oneself; Scavenge duct replenishes the air of lower temperature to bottom cavity from the heating space by air admission hole, the air that is arranged in heating space, main heating board top is heated by main heating board upper surface, form the circulation heating, the air in heating service space gradually, in this process, bottom cavity is equal substantially with the air themperature of heating in the space, when temperature rise when setting value, heating stops, and realizes thermostatic control; So the warmer temperature rise is fast, thermal efficiency height, temperature precise control.Simultaneously, small amount of hot air, reaches heating and feels comfortable purpose for the heating of heating person's upper body position by appearing in the felting overcover slit.Longer when the heating time, heating person thinks that the air of heating in the space is stale, and needs to replenish and when changing a large amount of fresh air, can suitably adjust felting overcover position, and the air admission hole that scavenge duct is advanced gets final product with the ambient air connection.
