Abstract

PURPOSE:To prevent an operation knob from becoming loose or being detached by constituting integrally the operation knob for adjusting a thermostat, a temperature displaying pointer and a bar for connecting it to a transfer mechanism. CONSTITUTION:To a pedestal 3a provided projectingly on the outside periphery of a hot plate 3, a thermostat 6a is attached. To a temperature indicating pointer 12a of a temperature setting mechanism 16 in which an operation knob 11a and the temperature indicating needle 12a are formed integrally, a bar 10a is coupled integrally, and this bar 10a is connected to a transfer mechanism 7a such as a gear connected to the thermostat 6a. When the operation knob 11a is moved to a desired position, the temperature indicating needle 12a also moves in cooperation therewith, and displays a set temperature on a temperature display part 15. Simultaneously, the bar 10a also moves, and the thermostat 6a is adjusted through the transfer mechanism 7a. In such a way, feed to the heater 4 is controlled so that a heating plate 5 is heated to a desired temperature, and cooking in the heating plate 5 by a desired temperature can be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a heating cooker for cooking grilled meat, hot pot dishes, etc. on a plate.

[Prior Art] Cooking devices that are placed on a dining table or the like to heat and keep food warm during meals are widely used.

FIG. 3 is an enlarged sectional view of the main parts of an example of a conventional heating cooker. In the figure, (l) is a guard provided on the outer periphery of the cooking device to prevent burns to the user; (2)
is a reflector for heat insulation fixed inside the guard (1), (3)
is a hot plate fixed to the top of the reflector (2), and (4) is a heater formed as an insert on the bottom of the hot plate (3).

(5) is a heating plate which is detachably attached to the upper part of the heating plate (3) and is used for cooking on the inner surface. (6
〉 is a thermostat for temperature adjustment installed almost at the center of the hot plate (3) inside the guard (1), (7〉
is a gear for switching the thermostat (6>), (8> is a lever rotatably supported on the shaft (9), and one end is connected to the gear (7); (l1) is the heating plate ( 5) is an operation knob for setting the temperature to a desired value, (12) is a temperature display pointer whose one end ({4) is connected to a lever (8) via a bar (1o), and (l3) is a A mounting bracket 05) for attaching the operating knob (l1) to the temperature display pointer (12) is a temperature display section.

Next, the effect will be explained. When the operation knob (11) is moved in a direction perpendicular to the page, the temperature display pointer (l2) connected thereto also moves, and the desired temperature (set temperature) is displayed on the display section (l5). On the other hand, the operation knob (11) is moved by rotating the lever (8> through the bar (10>) and adjusting the thermostat (6> through the gear (7) according to the set temperature. In this state, When power is supplied to the heater (4), the heating plate (5>) is heated via the heating plate (3).The thermostat (6>) senses the temperature of the heating plate (3>) and responds to the temperature of the heating plate (3). The temperature of the heating plate (5) is maintained at approximately the set temperature by controlling the power supply to the heating plate (5).The thermostat (6) senses the temperature of the heating plate (5) and responds by controlling the power supply to the heater (4). control the power supply.

[Problems to be Solved by the Invention] According to the conventional heating cooker configured as described above, in order for the connecting lever (8) to rotate smoothly, the lever (8)
Since a certain gap must be provided between the connecting part of the control knob (11) and the temperature display pointer (l2), play may occur, which may cause the operating knob (11) to feel unnatural or cause the operating knob (11) to If a strong force is applied, the control knob (11)
There were problems such as the screw coming off from the mounting bracket (l3).

The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide a cooking device in which the operation knob does not rattle or come off.

[Means for Solving the Problems] The heating cooker according to the present invention integrally includes an operation knob for a temperature setting mechanism that adjusts a thermostat, a temperature display pointer, and a bar that connects the temperature display pointer to a transmission mechanism. This is what I did.

[Action] When the operating knob is moved to a predetermined temperature position, the thermostat is adjusted via a transmission mechanism connected to the bar, and power supply to the heater is controlled so that the heating plate is heated to the desired temperature.

[Embodiment] FIG. 1 is an exploded perspective view of an embodiment of the present invention, and FIG. 2 is a longitudinal sectional view of the embodiment of the present invention. Note that the same or corresponding parts as in the conventional example shown in FIG. 3 are given the same reference numerals, and the explanation thereof will be omitted. In the figure, (3a) is a pedestal that protrudes from the outer periphery of the heat plate (3), and a thermostat (6a) is attached to this pedestal. (16) is an operating knob (lla) and a temperature indicator ( 12a) is integrated into the temperature setting mechanism, and a bar (10a) is integrally connected to the temperature indicating pointer (12a), and this bar (10a) is connected to a thermostat (6a>). It is connected to a transmission mechanism (7a) such as a gear. Note that (l7) is a lid having a knob (t8), and (19> is a power cord).

Next, the operation of the present invention configured as described above will be explained.

When the operating knob (lla) is moved to a desired position, the temperature indicating pointer (12a) also moves together with this, and the set temperature is displayed on the temperature display section (l5). At the same time, the bar (10a) also moves, and the thermostat (6) is adjusted via the transmission mechanism (7a). This allows the heater (4) to heat the heating plate (5) to the desired temperature.
) is controlled, allowing cooking within the heating plate (5) at a desired temperature.

As described above, according to the cooking device of the present invention, only a slight wobbling of the operation knob (log) constituting the setting mechanism (16) occurs between the operation knob (log) and the transmission mechanism (7a).
The overall wobbling is smaller than before. In addition, the temperature setting mechanism (l6) has a structure that integrates the operating knob (lla), the temperature display pointer (12a), and the bar (loa), so the operating knob (lla) does not come off and is easy to assemble. Since it is only necessary to assemble the operating knob (lla) in a predetermined position, the number of assembly steps can be reduced and costs can be reduced.

[Effects of the Invention] As is clear from the above description, according to the present invention, the operation knob for adjusting the thermostat in conjunction with the setting of the desired temperature, the temperature display pointer, and the bar are integrally configured, so the cost is reduced. You can get a heating cooker with high temperature control accuracy.
