Abstract
The utility model relates to a heating pipe of dish washer, including heating body (1), heating body (1) both ends are the linearity, its characterized in that heating body (1) middle part is the bending of multilayer multifolding. The utility model adopts the structure that the middle part of the heating pipe is multi-layer and multi-fold bent, and the expansion length of the heating pipe is long, thereby increasing the contact area between the heating pipe and the liquid and increasing the thermal conductivity of unit area; under the condition of constant rated power, the heat load (W/cm) of the surface of the heating pipe2) The service life of the heating pipe is greatly prolonged; in addition, because the heat load on the surface of the heating pipe is small, the surface temperature is low, scale is not easy to form, and the heat of the heating pipe can be quickly transferred to the heated liquid.
Description
Technical field:
The utility model is a kind of heating tube of dishwasher, belongs to the improvement technology of dishwasher heating tube.
Background technology:
The heating tube of existing dishwasher as shown in Figure 1, its two ends are linearity, the centre is plane individual layer bending, there is following shortcoming in the heating tube of this kind structure: the heating tube length of run is less, and is also little with the contact area of liquid, the pyroconductivity of unit are is low; Under the certain situation of rated power, the surface thermal load (W/cm of heating tube
2) bigger, useful life is lower; In addition,, make that the heating tube surface temperature is higher, form incrustation scale easily because surface thermal load is bigger, also more and more along with heating tube operating time lengthening attached to the incrustation scale on heating tube surface, be unfavorable for that the heat of heating tube is delivered to heated liquid as early as possible.
The utility model content:
The purpose of this utility model is to consider the problems referred to above and a kind of pyroconductivity that can increase unit are is provided, and improves useful life, is difficult for forming incrustation scale, the heating tube of the dishwasher that heat transferred is fast.
The technical solution of the utility model is: a kind of heating tube of dishwasher, comprise the heating body, and heating body two ends are linearly, and the middle part is many bendings of multilayer song.
The utility model is because employing heating tube middle part is the structure of many bendings of multilayer song, and the heating tube length of run is long, thereby has increased the contact area of heating tube and liquid, and the pyroconductivity of unit are increases; Under the certain situation of rated power, the heat load (W/cm on heating tube surface
2) less, prolonged useful life of heating tube greatly; In addition, because the heat load on heating tube surface is less, surface temperature is lower, is not easy to form incrustation scale, and the heat of heating tube can be delivered to heated liquid fast.
Description of drawings:
Fig. 1 is the structural representation of prior art heating tube;
Fig. 2 is a structural representation of the present utility model.
Embodiment:
Embodiment 1:
As shown in Figure 2, the heating tube of present embodiment dishwasher comprises heating body 1, and heating tube 1 two ends are linearly, and the middle part is two-layer many bendings song.
Claims (1)
1, a kind of heating tube of dishwasher comprises heating body (1), and heating body (1) two ends are linearly, it is characterized in that described heating body (1) middle part is many bendings of multilayer song.
