Description
Technical field
The invention belongs to the technical field of electromagnetism heating, particularly relate to a kind of water-cooled electromagnetic heater.
Background technology
Traditional electromagnetic oven adopts air-cooled structure to dispel the heat, and owing to air-cooled structure exists various shortcoming, people constantly attempt designing the electromagnetic oven of water-cooling structure heat radiation. But, effective and rapid the transmissions feedwater of the heat how electromagnetic heating coil produced, and how to make water-cooled electromagnetic stove stove structure compact, easy for installation, be still problem to be solved so far.
Existing water-cooled electromagnetic stove stove is provided with electromagnetic heating coil, heat dissipation plate, cooling water tank, electric controling element, electromagnetic heating coil is close to heat dissipation plate, heat dissipation plate also needs a supporting heat dissipation plate support again, heat dissipation plate has offered water stream channel, water-in, the water outlet of water stream channel are connected to cooling water tank by water inlet pipe, rising pipe respectively, electric controling element is not only needed to be detected by signal wire and controls the state of cooling water tank accessory (comprising water pump), and needs to be detected by signal wire and control the working order of electromagnetic heating coil.
Existing above-mentioned water-cooled electromagnetic stove stove exists following not enough:
One, due to the bulky heaviness of electromagnetic oven, therefore at place of manufacturer, whole cooking stove can not be installed and then entirety is transported to the kitchen of user, and each several part can only be taken apart and be transported to the kitchen of user, finally just assemble at the kitchen place of user, the operation of assembling be first by each parts respectively one by one fixing and locking on the main body frame of electromagnetic oven, and then the light current carried out between each parts connects, forceful electric power connects, water connects, therefore field installation procedure is complicated, particularly electric component and water fittings dispersion, interface is numerous, therefore field assembly trouble, particularly user cannot assemble at all voluntarily, therefore a water-cooled electromagnetic stove stove is often sold, producer all needs in-site installation of sending someone, have impact on the convenience that it is promoted the use of,
Two, in use procedure if there is fault time, user by oneself, cannot can only wait that manufacturer sends someone maintenance of visiting, it is determined that after trouble location, row is repaired again, this process is it is generally required to the time of several days, and general used by hotels and restaurants by dining room is difficult to tolerate that its commercial electromagnet cooking stove is stopped using several days;
Three, heat dissipation plate needs to be formed helical flow of water passage therein, therefore makes trouble;
Four, owing to the water yield in heat dissipation plate is little, therefore the heat radiation efficiency of heat dissipation plate is poor, and working process all needs to rely on all the time the powerful promotion of water pump could realize the water circulation heat radiation of heat dissipation plate, if water pump breaks down, then the water of heat dissipation plate is owing to the water yield that contains is few and can not flow, and must significantly heat up rapidly and lose heat-sinking capability.
Summary of the invention
It is an object of the invention to overcome above-mentioned shortcoming and provide a kind of water-cooled electromagnetic heater, its heat radiation is quick reliable, and structure is compacted, and in-site installation is convenient.
