Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermostats, and particularly relates to a knob thermostat. Background Art
[0002] The knob thermostat is applied to the heating control and over-temperature protection of electric water heaters. An insertion rod assembly composed of a temperature sensing cylinder and a nickel rod with two different coefficients of thermal expansion is used to sense the rise and fall of the water temperature inside the water tank, causing expansion or contraction to turn on or off a group of switches, thereby realizing temperature control. The over-temperature protection is realized by the sudden jump and flip of a bimetallic disc to push another group of switches to disconnect. The existing knob thermostat usually uses a knob to assist in rotating and adjusting a nut, and the knob can also indicate the temperature information at this time. However, when the knob is accidentally pulled out or damaged and needs to be replaced, when reinstalling the knob, because the temperature information of the adjusting nut cannot be distinguished at this time, after reinstalling or replacing the knob, there will be a deviation between the temperature information indicated by the knob and the actual temperature information, and the temperature information needs to be recalibrated.

[0021] In the description of the present utility model, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the technical field can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.
[0022] Refer to Figures 1 to 3 As shown, a knob thermostat includes a lower cover 100, an adjusting nut 200, a nickel rod 300, a temperature sensing cylinder 400, and further includes a bearing plate 500. One end of the bearing plate 500 is riveted to the lower cover 100 to prevent the bearing plate from shaking. The other end of the bearing plate 500 is provided with an adjusting screw 600. A moving contact piece 700 is arranged below the adjusting screw 600. The adjusting nut 200 is installed at the top end of the nickel rod 300, and the adjusting nut 200 is located above the bearing plate 500; the adjusting nut 200 is provided with a vertical section 201, an adjusting knob 102 is installed on the adjusting nut 200, and an installation hole is arranged inside the adjusting knob 102, and a vertical surface 1010 is arranged inside the installation hole.
[0023] Since the adjusting nut 200 is provided with a vertical section 201, which is convenient for indicating the direction, when the adjusting knob 102 is accidentally pulled out or replaced, the vertical surface 1010 inside the installation hole is matched with the vertical section 201 of the adjusting nut 200, so that after the adjusting knob 102 is reinstalled, the temperature information indicated by it will not deviate, thus affecting the product performance.
[0024] The adjusting screw 600 can be adjusted in both forward and reverse directions, so the adjustment accuracy of the adjusting screw 600 is higher than that of the existing gear adjustment method.
[0025] Refer to Figure 3 、 4As shown, the left terminal 2000 contacts or disconnects from the left reed 4000. The left reed 4000 is riveted to the lower cover 100. A moving contact piece 700 is riveted to the right terminal 3000. The bridge piece 6000 contacts or disconnects from the moving contact piece 700 and the right reed 5000. The right reed 5000 is riveted to the lower cover 100. The left reed 4000 is connected to a left threaded terminal 7000, and the right reed 5000 is connected to a right threaded terminal 8000 to achieve the opening and closing of the circuit.
[0026] Referring to Figure 1 As shown, the reset rod 900 and the bimetal piece 1000 are successively sleeved on the nickel rod 300. The reset rod 900 includes a sleeve portion 910, a left ejector rod portion 920, and a right ejector rod portion 930. The sleeve portion 910 is sleeved on the nickel rod 300 and contacts the bimetal piece 1000. The left ejector rod portion 920 abuts against the bottom of the left reed 4000, and the right ejector rod portion 930 abuts against the bottom of the right reed 5000.
[0027] When the temperature sensing cylinder 400 expands and elongates or contracts and shortens as the temperature rises or falls, it drives the nickel iron rod and the temperature regulating nut 200, which can be regarded as not expanding or contracting, to move downward or upward simultaneously, causing the bimetal piece 1000 to be lifted and pushing the reset rod 900, so that the left terminal 2000 disconnects from the left reed 4000, and the bridge piece 6000 disconnects from the moving contact piece. When resetting, just press the reset rod 900 downward.
[0028] The reset rod 900 further includes a reset pressing rod 940, and the reset pressing rod 940 penetrates through the upper cover 101.
[0029] Referring to Figure 2 As shown, specifically, a spring 610 is sleeved on the adjusting screw 600, and the spring 610 presses above the bearing plate 500.
[0030] A positioning post 310 is sleeved on the nickel rod 300, and the positioning post 310 is installed in the temperature sensing cylinder 400 to prevent the nickel rod 300 from swaying around and causing shaking, which affects the displacement of the nickel rod 300 and ultimately affects the temperature control.
