The water system 33 includes a water inlet valve 331, a water outlet valve 332, a connecting water pipe 333 and a hot water pipe (not shown in the figure). In this embodiment, the water inlet valve 331 and the water outlet valve 332 are respectively arranged on the left and right sides behind the burner. The cold water outlet of the water inlet valve 331 is connected to the first water inlet 3111 through the connecting water pipe 333, so that tap water or cold water can flow from the water inlet valve 331 and the connecting water pipe 333 to the burner in sequence. The water inlet valve 331 is used to control the on-off state of the water inlet. The hot water inlet 3321 of the water outlet valve 332 is connected to the first water outlet 3112 through the hot water pipe, and a hot water outlet 3322 is arranged on the water outlet valve 332. In this way, the hot water heated by the burner flows from the hot water pipe to the water outlet valve 332, and then flows out from the hot water outlet 3322, so as to provide hot water for the user.

[0032] The smoke exhaust system 34 includes a fan 341, which is arranged in front of the burner. The air inlet of the fan 341 faces the smoke outlet of the burner and is connected to the inside of the box assembly 11 of the box module. The air outlet of the fan 341 is connected to the drum 21, and is used to collect and discharge the high-temperature smoke generated by the burner into the drum 21, so as to achieve the use of high-temperature smoke for drying clothes.

[0033] In this embodiment, the burner includes an outer shell 311, a burner body 312 and a main heat exchanger 313. The outer shell 311 is arranged between the gas path system 32 and the air inlet of the fan 341. The front end of the outer shell 311 is open to form a smoke outlet.

The water system 33 also includes a cold water pipe (not shown in the figure), and the cold water outlet of the water inlet valve 331 is connected to the second water inlet 3141 through the cold water pipe. As a result, tap water or cold water first flows through the condensing heat exchanger 314, is preliminarily heated by the condensing heat exchanger 314, and then flows to the main heat exchanger 313 of the burner, and is heated again, so as to realize secondary heating of water, which is conducive to increasing the outlet water temperature.

[0035] The smoke exhaust system 34 also includes a smoke exhaust channel 342, a fan 341 is arranged between the condensing heat exchanger 314 and the burner, and the smoke exhaust channel 342 is arranged between the condensing heat exchanger 314 and the drum 21. The upper end of the smoke exhaust channel 342 is connected to the drum 21, and the lower end is connected to the air outlet of the fan 341 through the smoke collecting chamber. As a result, the high-temperature flue gas generated by the operation of the burner, under the action of the fan 341, first flows to the condensing heat exchanger 314 and exchanges heat with the water flowing through the condensing heat exchanger 314, and then flows to the drum 21 through the smoke exhaust channel 342 and dries the clothes in the drum 21, so as to realize the secondary utilization of high-temperature flue gas and reduce resource waste. It is particularly noted that the condensing heat exchanger 314 in the combustion system 31 can be omitted. At this time, the lower end of the smoke exhaust channel 342 is configured to be directly connected to the air outlet of the fan 341.

[0036] refer to Figure 4 Furthermore, the water system 33 also includes a support seat 334, which is arranged at the bottom of the box assembly 12 of the box module and is located behind the burner. The water inlet valve 331 and the water outlet valve 332 are respectively installed at the left and right ends of the top of the support seat 334, and the gas valve 321 is arranged at the top of the support seat 334 and is located between the water inlet valve 331 and the water outlet valve 332. In this way, it is convenient to install the water inlet valve 331, the water outlet valve 332 and the gas valve 321 in the box assembly 12 through the support seat 334.

[0037] A first positioning structure is provided between the support seat 334 and the water inlet valve 331, and a second positioning structure is provided between the support seat 334 and the water outlet valve 332.

Positioning columns 3341 extending upward are provided at the left and right ends of the top of the support seat 334, respectively. Positioning grooves are provided at the positions of the positioning columns 3341 of the water inlet valve 331 and the water outlet valve 332. The water inlet valve 331 and the water outlet valve 332 can be positioned at the top of the support seat 334 by matching and plugging the positioning columns 3341 with the corresponding positioning grooves.

[0038] At least one mounting hole 3342 is provided at the position of the support seat 334 corresponding to the water inlet valve 331 and the water outlet valve 332. A connecting piece (such as a screw) is inserted into the mounting hole and is fastened to the water inlet valve 331 or the water outlet valve 332, so that the water inlet valve 331 and the water outlet valve 332 are fixedly mounted on the support seat 334 to prevent the water inlet valve 331 and the water outlet valve 332 from shifting relative to the support seat 334. In addition, a plurality of press profiles 3343 extending upward are integrally formed on the top surface of the support seat 334, all of which are located between the two positioning columns 3341, and a heat dissipation channel is formed between adjacent press profiles 3343. In this way, by providing the press profiles 3343 and the heat dissipation channel, the strength of the support seat 334 is strengthened and the supporting effect is improved. Secondly, the friction between the gas valve 321 and the top surface of the support seat 334 is increased, and the contact area between the two is reduced, so that the gas valve 321 is easily dissipated through the heat dissipation channel to prevent the temperature rise of the gas valve from being too high.

[0039] refer to Figure 3-5 , further, an exhaust portion 211, a partition and a rotating shaft 214 are provided on the back of the drum 21, the rotating shaft 214 is located at the center of the back of the drum 21, the partition and the exhaust portion 211 are both arranged on the periphery of the rotating shaft 214, and the partition divides the exhaust portion 211 into a plurality of sub-exhaust hole groups arranged at intervals in the circumferential direction, and each exhaust hole group is composed of a plurality of air holes. In this embodiment, the partition includes a plurality of strip-shaped profiles 212 and an annular profile 213, the annular profile 213 is arranged between the exhaust portion 211 and the rotating shaft 214, all the strip-shaped profiles 212 are arranged at intervals in the circumferential direction on the periphery of the annular profile 213 and are integrally formed with the annular profile 213, and all the strip-shaped profiles 212 divide the exhaust portion 211 into a plurality of sub-exhaust hole groups arranged at intervals in the circumferential direction. It can be seen that by cooperating with a plurality of strip-shaped profiles 212 and annular profiles 213, the exhaust portion 211 can be partitioned while strengthening the overall strength of the back of the drum 21.

[0040] The smoke exhaust assembly 22 includes an air guide hood 221 and an air outlet seat 222. The air guide hood 221 is disposed on the back of the drum 21 and is sealed and connected to the drum 21.
