Definitions

  • the present invention relates to an operation apparatus for a cooktop, and in particular, to an operation apparatus for a cooktop having a light-emitting member and gear marks, and a cooktop having the operation apparatus.
  • knobs capable of emitting light on existing cooktops light generally only plays a role of decoration, or an open/closed state of a cooktop is displayed by simply using ON/OFF of light. Information transmitted by such light-emitting knobs to users is limited, and a current fire/power state of a cooktop cannot be displayed through light. Moreover, some knobs may emit light in different colors, so as to display different fire/power of the cooktop. However, a gas cooktop produces open fire at work, the burning flame interferes with a user's judgment on the color of a knob to some extent, and thus the user cannot accurately identify the current fire/power. In addition, it is worth mentioning that those skilled in the art have formed a deep-rooted understanding that light sources of the knobs capable of emitting light are all fixedly set and will not rotate with rotation of the knobs, because line connection of rotating light sources is a problem.
  • An objective of the present invention is to solve the above at least one technical problem, and therefore, an operation apparatus for a cooktop that displays a relative size of a current fire/power of a cooktop more directly and accurately, and a cooktop having the operation apparatus are provided.
  • an operation apparatus for a cooktop having at least two gears
  • the operation apparatus including a panel, a rotation shaft and a knob
  • the panel has at least two light-transmissive gear marks
  • the rotation shaft is at least partially located on an inner side of the panel
  • the knob is at least partially located on an outer side of the panel, for driving the rotation shaft to rotate.
  • the operation apparatus further includes a connecting element located on the inner side of the panel, connected to the rotation shaft and rotating under the driving of the rotation shaft when the rotation shaft rotates; and the connecting element is provided with a light-emitting member, and one gear mark on the panel is lit up by light of the light-emitting member when the knob rotates to one gear of the operation apparatus.
  • the gear mark lit up correspondingly displays the current gear of the operation apparatus, so that users can intuitively and accurately obtain power/fire size information of the cooktop. Even if in a situation in which a kitchen is dim, the users, when standing, can clearly see the light-emitting gear mark without frequently bending down to check the power/fire size of the cooktop.
  • the panel included in the operation apparatus may be understood as a panel for closing some parts of the operation apparatus inside the cooktop, so as to protect the parts from contamination by dirt and soup.
  • the panel may be a cooktop panel.
  • the present invention has a simple structure, some technical features can be naturally merged into the structure of the existing cooktops, for example, light-transmissive gear marks may be disposed on the cooktop panel, the manufacturing cost is low, and the present invention is less limited by the number of gears.
  • the present invention overcomes technical bias, to enable the light-emitting member to rotate with the rotation shaft, and light of the light-emitting member is rotatably irradiated to the light-transmissive gear marks on the panel directly; in this way, it is unnecessary to dispose an element making light selectively transmit or irradiate between the light-emitting member and the panel.
  • "located on an outer side of the panel" in the present invention can be understood as being located on one side of the panel facing the outside, which is a side that often can be seen by the users in a use state of the cooktop.
  • the gear marks may be numbers such as 0-9, symbols or patterns such as different sizes of gas flames.
  • the gear marks may be formed through printing, coating, laminating or etching.
  • the connecting element includes a light-transmissive portion, and the light of the light-emitting member is evenly emitted to the panel through the light-transmissive portion. Light emitted from different angles of the light-emitting member is concentrated on the front of the light-transmissive portion, thereby improving brightness and evenness of the gear marks.
  • the light-transmissive portion includes a light exit surface facing the panel, and a distance (d) from the light exit surface to the panel is within a range of 0.5 mm ⁇ d ⁇ 2 mm. In this way, the light of the light-emitting member can be gathered in a corresponding position on the panel, to ensure that the required position has sufficient brightness, which will not cause that gear marks adjacent to the gear mark lit up are lit up to some extent.
  • the light exit surface is a matte surface.
  • the light-transmissive portion is made of an acrylic material, or the light-transmissive portion is made of a polycarbonate material to which a light diffusant is added.
  • the connecting element is disk-like.
  • the mold is simple and manufacturing is easy.
  • the connecting element includes a groove that receives the light-emitting member, and the light-transmissive portion is located at the top of the groove.
  • the connecting element is made of an opaque material, and the light-transmissive portion is assembled at the top of the groove; or the light-transmissive portion is formed integrally by the connecting element, the connecting element is made of a light-transmissive material, and an opaque material is coated or an opaque film is pasted on a surface of the connecting element facing the panel except the top of the groove. That the light-transmissive portion is formed integrally by the connecting element saves the trouble of manual assembly of the light-transmissive portion.
  • the operation apparatus for a cooktop further includes a circuit board that controls ON/OFF of the light-emitting member, where the light-emitting member includes a connecting pin, and the connecting pin rotatably contacts the circuit board when the connecting element rotates.
  • the technical solution creatively solves the problems of line connection and control of the rotating light-emitting member, which is a great progress compared with the existing technologies.
  • the damaged light-emitting member can be replaced with a light-emitting member individually, but the circuit board does not need to be replaced, which can save the maintenance cost.
  • the rotation shaft is capable of moving axially under the driving of the knob, and the connecting pin flexibly contacts the circuit board when the connecting element moves along an axial direction of the rotation shaft.
  • the present invention further provides a cooktop, including the operation apparatus for a cooktop as described above.
  • the gears of the cooktop of the present invention can be intuitively displayed on the panel, and users can accurately judge relative sizes of fire/power accordingly.
  • light-emitting gear marks are displayed on the panel, which also adds a sense of fashion to the appearance of the cooktop.
