Abstract
The utility model discloses an automatic temp-adjusting electric stove, composed of an electric heating wire (3), a cooker plate (4) and a support frame (5), wherein, a screw which passes through the central through hole of the cooker plate is screwed into the support frame to fix the cooker plate. A screw (9) is a heat-conducting metal screw whose lower end is tightly connected with an adjustable dual-metal temperature controlled switch (7) arranged at the bottom of the support frame (5), and the normally-closed contact of the temperature controlled switch (7) is connected in series in the electric source return circuit of the electric heating wire (3). The utility model has the advantages of simple structure and safety with automatic temperature adjustment, being adaptable for cooking congee, stewing soup, decocting Chinese medicinal materials in slow fire, etc. and being convenient for users.
Description
The utility model relates to electric heating appliance, more particularly, be a kind of be heating element heater with the heating wire that evenly is arranged in the stone or metal plate for standing a stove on as a precaution against fire groove, especially as the automatic temperature-control electric furnace of electrothermal cooker tool.
Electric furnace of the prior art and have the electrothermal cooker tool such as electric cup, electric frying pan of same heating arrangement with electric furnace does not have the automatic regulatory function of temperature.Continuous high temperature heating makes these cooking appliances be unsuitable for being used for slow fire and cooks congee, burns soup or decoct Chinese medicine etc.Often because user carelessness, the food of being hotted plate is excessive, and the corroded by liquid that electric heating appliance is overflowed damages, serious in, the liquid that overflows can cause whole electric power loop short circuit, causes damage.
The purpose of this utility model is to avoid the deficiencies in the prior art part, and a kind of automatic temperature-control electric furnace is provided, and with its heater as cooking appliance, can carry out temperature within the specific limits and regulate automatically, the convenient use.
The purpose of this utility model is achieved through the following technical solutions.
The utility model is by heating wire, stone or metal plate for standing a stove on as a precaution against fire and be configured to, and heating wire evenly is arranged in the stone or metal plate for standing a stove on as a precaution against fire upper surface groove, and stone or metal plate for standing a stove on as a precaution against fire is placed on the support, and there is a through hole in stone or metal plate for standing a stove on as a precaution against fire central authorities, and screw passes this through hole and screws in support.
Of the present utility model being characterised in that: described screw adopts the heat-conducting metal screw, the screw lower end closely contacts with the adjustable bimetallic temperature detect switch (TDS) that is arranged on frame bottom, and a pair of normally closed interlock of described bimetallic temperature detect switch (TDS) is serially connected in the electric power loop of heating wire.
The utlity model has following advantage.
The utility model can automatically adjust its serviceability temperature by adjustable bimetallic temperature detect switch (TDS) is set within the specific limits.It is simple in structure, safe and reliable.With its heater block as device for cooking, the cooking appliance that is constituted is suitable for slow fire and cooks congee, simmers soup, decocts Chinese medicine etc., is very easy to the user.
Accompanying drawing is the utility model structural representation.
Number in the figure: 1, bowl cover, 2, cup, 3, heating wire, 4, stone or metal plate for standing a stove on as a precaution against fire, 5, support, 6, even heat plate, 7, temperature detect switch (TDS), 8, adjusting knob, 9, screw, 10, screw rod.
By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Present embodiment is an electric cup, as shown in drawings.The body of heater that comprises bowl cover (1), cup (2) and cup (2) bottom.Body of heater is made of heating wire (3), stone or metal plate for standing a stove on as a precaution against fire (4) and support (5).Stone or metal plate for standing a stove on as a precaution against fire (4) upper surface is offered groove, and there is a through hole in central authorities.Heating wire (3) evenly is arranged in the stone or metal plate for standing a stove on as a precaution against fire groove, stone or metal plate for standing a stove on as a precaution against fire (4) is placed on the support (5), at support (5) bottom center stationary adjustable formula bimetallic temperature detect switch (TDS) (7), there is a long spiro nail (9) to pass stone or metal plate for standing a stove on as a precaution against fire (4) center through hole, and screwing in support (5), its lower end closely contacts with temperature detect switch (TDS) (7).Screw (9) is fixed in stone or metal plate for standing a stove on as a precaution against fire (4) on the support (5) on the one hand, and the temperature with stone or metal plate for standing a stove on as a precaution against fire (4) passes to temperature detect switch (TDS) (7) on the other hand, and screw (9) adopts the metallic screw with good heat conductive performance.The thermoregulation knob (8) of temperature detect switch (TDS) (7) is positioned at support (5) lateral wall, is connected by screw rod (10) between adjusting knob (8) and the temperature detect switch (TDS) (7).
Between cup (2) and body of heater, the upper surface that is positioned at stone or metal plate for standing a stove on as a precaution against fire (4) is placed even heat plate (6), and even heat plate (6) is the porcelain flat board.
The a pair of normally closed interlock of temperature detect switch (TDS) (7) is serially connected in the electric power loop of heating wire (3).Connect when power switch, electric furnace begins heat temperature raising, and when being warming up to setting value, the normally closed interlock of temperature detect switch (TDS) (7) opens circuit, stop heating, after this rely on residual heat insulation, be reduced under the temperature detect switch (TDS) until temperature and prescribe a time limit, its normally closed interlock is connected heavily again, so circulation, and the realization temperature is regulated automatically.Rotate adjusting knob (8), make it be in different positions, can make normally closed interlock break-make under different temperature values, under different temperatures, regulate automatically to realize electric furnace.
Claims (3)
1, a kind of automatic temperature-control electric furnace, by heating wire (3), stone or metal plate for standing a stove on as a precaution against fire (4) and support (5) constitute, described heating wire (3) evenly is arranged in stone or metal plate for standing a stove on as a precaution against fire (4) the upper surface groove, stone or metal plate for standing a stove on as a precaution against fire (4) is placed on the support (5), there is a through hole in stone or metal plate for standing a stove on as a precaution against fire (4) central authorities, screw (9) passes this through hole and screws in support (5), it is characterized in that: described screw (9) adopts the heat-conducting metal screw, screw (9) lower end closely contacts with the adjustable bimetallic temperature detect switch (TDS) (7) that is arranged on support (5) bottom, and a pair of normally closed interlock of described bimetallic temperature detect switch (TDS) (7) is serially connected in the electric power loop of heating wire (3).
