[0040] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments, rather than all the embodiments.

[0041] Example 1

[0042] like Figures 1 to 5 As shown, this embodiment provides a heat recovery system for a drying area of ​​a dishwasher, including a water supply pipeline (not shown) and a heat exchanger 10, wherein the water supply pipeline is connected to the heat exchanger 10, and the heat exchanger 10 is configured under the tableware conveyor of the dishwasher for heat exchange.

[0043] In this embodiment, a plurality of elastic heat-conducting tentacles 20 are provided on the heat exchanger 10 . The elastic heat-conducting tentacles 20 are used to contact with the chain links of the tableware conveyor, so as to transfer the heat on the chain links to the heat exchanger 10 .

[0044] By providing a plurality of elastic heat-conducting tentacles, the contact area between the entire system and the hot air in the drying area of ​​the dishwasher can be increased, the heat transfer effect can be improved, and thus the heat exchange efficiency can be improved.

[0045] In this embodiment, the elastic heat-conducting antenna 20 is bent toward the conveying direction of the tableware conveyor to form an arc structure.

[0046] Since the elastic heat-conducting antenna 20 adopts a curved arc structure and the elastic heat-conducting antenna 20 is bent toward the conveying direction of the tableware conveyor, less resistance is caused to the tableware conveyor.

[0047] In this embodiment, the outer surface of the elastic thermal conductive antenna 20 is covered with a thermal conductive rubber protective sleeve 30. The thermal conductive rubber protective sleeve 30 can provide a good buffering effect and reduce the noise generated when the elastic thermal conductive antenna 20 collides with the link.

[0048] In this embodiment, the heat exchanger 10 includes a retaining frame 11 , a heat exchange pipe 12 and a plurality of heat exchange plates 13 .

[0049] Furthermore, the heat exchange pipe 12 is configured to be fixedly connected to the retaining frame 11 , a plurality of heat exchange plates 13 are disposed in the retaining frame 11 , and both the retaining frame 11 and the heat exchange pipe 12 are fixedly connected to the plurality of heat exchange plates 13 .

[0050] In this embodiment, the elastic heat-conducting antenna 20 is detachably connected to the heat exchange pipe 12, the plurality of heat exchange plates 13 are distributed at equal intervals, and the plurality of elastic heat-conducting antennas 20 are distributed in a rectangular array.

[0051] Specifically, an insertion groove 131 is provided on the upper end surface of the heat exchange plate 13, and an insertion block 21 matching the insertion groove 131 is provided at the bottom end of the elastic heat conductive antenna 20, and the elastic heat conductive antenna 20 and the heat exchange plate 13 are detachably connected through the insertion groove 131 and the insertion block 21. The elastic heat conductive antenna 20 is easy to install and easy to disassemble, so that the staff can easily replace the elastic heat conductive antenna 20.

[0052] Furthermore, a pull ring 22 is provided on the insertion block 21, and the pull ring 22 is configured to be fixedly connected to the insertion block 21. A plug hole (not shown) is provided on the heat-conducting rubber protective sleeve 30, and the head end of the elastic heat-conducting antenna 20 is inserted into the plug hole.

[0053] In this embodiment, the insert block 21 is a thermally conductive ceramic insert block, and the elastic thermally conductive whiskers 20 are fixedly connected to the thermally conductive ceramic insert block.

[0054] Exemplarily, the elastic thermal conductive whisker 20 is fixed to the insert block 21 by means of implanted reinforcement.

[0055] Example 2

[0056] like Figure 6 As shown, this embodiment discloses a heat recovery system for a drying area of ​​a dishwasher, which is substantially the same as the first embodiment, except that a spherical beating portion 31 is provided at the top of the heat-conducting rubber protective sleeve 30, and the spherical beating portion 31 is integrally provided with the heat-conducting rubber protective sleeve 30. The spherical beating portion 31 can further enhance the buffering effect.

Both the positioning groove 211 and the positioning protrusion are hexagonal structures.

[0059] After the insertion block 21 is inserted into the insertion slot 131, the insertion block 21 will not rotate during operation and has good stability. At the same time, the regular hexagonal structure is adopted, which allows the staff to adjust the swing direction of the elastic thermal conductive tentacles 20 according to needs and has good flexibility.

[0060] like Figure 8 As shown, the utility model also provides a dishwasher, including a casing (not shown), a main washing chamber (not shown), a rinsing chamber (not shown), a drying chamber (not shown) and a tableware conveyor 40, and also includes a heat energy recovery system for the drying area of ​​the above-mentioned dishwasher.

[0061] Although the embodiments of the present application have been shown and described above, the scope of protection of the present invention is not limited thereto, and any changes or substitutions that are not conceivable through creative work should be included in the scope of protection of the present invention; unless explicitly stated, any element, action or instruction used in this document should not be interpreted as critical or necessary.
