Example two

Fig. 13 is a schematic structural diagram of a household appliance provided in the second embodiment of the present invention, and fig. 14 is a schematic structural diagram of an installation structure of a housing and a nixie tube assembly in a household appliance provided in the second embodiment of the present invention.

The present embodiment provides a household appliance 200, and the household appliance 200 may be a household appliance 200 having a display function, such as an induction cooker, an electric rice cooker, an electric kettle, or a health preserving kettle.

In this embodiment, taking an induction cooker as an example for explanation, specifically, the household appliance 200 includes a housing 210 and the nixie tube assembly 100 of any of the above embodiments disposed in the housing 210, wherein the housing 210 has a display area corresponding to the nixie tube assembly 100, and the display area is an irregular area, in this embodiment, as shown in fig. 14, the nixie tube assembly 100 is opposite to a side wall of the housing 210, the display area is located on the side wall of the housing 210, and the display surface 31 of the nixie tube 30 in the nixie tube assembly 100 is inclined toward an inner wall of the display area, so that even if the display area is the irregular area, since the display surface 31 of the nixie tube 30 is inclined by the support frame 20, the display surface 31 of the nixie tube 30 is closer to the inner wall of the display area, that is, an interval between the display surface 31 of the nixie tube 30 and the inner wall of the irregular display area is shortened, so that, the better display effect of the display area is ensured.

Meanwhile, in this embodiment, because the display surface 31 of the nixie tube 30 is inclined under the inclined support of the support frame 20, when the installation is performed, gaps with different distances between the display surface 31 of the nixie tube 30 and the outer wall of the display area are shortened, thereby reducing the distance between the display surface 31 and the outer wall of the display area, and improving the display brightness of the display surface 31 of the nixie tube 30 on the display area, so that a user can more easily identify the nixie tube when using the nixie tube, therefore, the household appliance 200 provided in this embodiment solves the problem that the display effect of a display part on the display area is not ideal due to inaccurate positioning between a display component on the display panel and a special-shaped display area in the existing cooking appliance, and the normal identification of the use state or the working mode of the cooking appliance by the user is influenced.

In this embodiment, when the display surface 31 of the nixie tube 30 is obliquely disposed, a gap between the display surface 31 of the nixie tube 30 and the inner wall of the display area is greatly reduced, but since the display area is a special-shaped area, the inner wall of the display area is a special-shaped area, and the display surface 31 of the nixie tube 30 is a plane, a certain gap still exists between the display surface 31 of the nixie tube 30 and the inner wall of the display area, in this embodiment, in order to eliminate gaps with different distances between the display assembly and the inner wall of the display area, the nixie tube 30 is more accurately positioned on the display area, specifically, a part of the inner wall of the display area is set as a plane, the display surface 31 of the nixie tube 30 is attached to the plane under the support of the support frame 20 in the nixie tube assembly 100, so that the display surface 31 of the nixie tube 30 and the inner wall of the display area are, further, the distance between the display surface 31 of the nixie tube 30 and the outer wall of the display area is further reduced, thereby improving the display brightness of the display area.

Meanwhile, in this embodiment, the display surface 31 of the nixie tube 30 is attached to the planar inner wall of the display area, so that the contact area between the circuit board 10 and the inner wall of the display area is increased, and thus the display area is not easily deformed or damaged when being impacted or impacted.

Meanwhile, in the embodiment, when the inner wall of the display area is set to be a plane, the display surface 31 of the nixie tube 30 can be attached to the inner wall of the display area, in the prior art, when the display area is an irregular area, such as an arc surface, the display panel is often configured as an arc-shaped display panel matched with the arc surface of the display area, so that the display component on the display panel is attached to the irregular display area, or the display surface 31 of the nixie tube 30 is provided as an arc-shaped surface, but when the display surface 31 of the display panel or nixie tube 30 is provided as an arc, the difficulty is high, and the display panel or the display component is easy to break in the bending process, in this embodiment, a part of the inner wall of the display area is directly set to be a plane, for example, a part of the irregular inner wall of the display area can be set to be a plane through a thinning process or a thickening process, therefore, the problem that the display panel or the display surface 31 of the nixie tube 30 is arranged to be arc-shaped, which causes great manufacturing difficulty is avoided.

In this embodiment, for further enhancing the display effect, specifically, the plane on the inner wall of the display area is thinned for the second time, for example, a groove recessed towards the outer wall of the display area is formed on the plane, and the groove bottom of the groove is a plane, so that the wall thickness of the display area is further thinned, and the light transmission is better.

In this embodiment, the display area may be specifically located on a side wall of the casing 210 and/or on a top wall of the casing 210, and in this embodiment, the casing 210 may specifically include an upper cover, a middle frame, and a bottom case, where the upper cover and the middle frame may be separately or integrally disposed, and the middle frame and the bottom case may be separately or integrally disposed, or the upper cover, the middle frame, and the bottom case are separately disposed, where a side wall of the middle frame is a curved surface, and the display area is located on the side wall of the middle frame.
