In some embodiments, as shown in connection with fig. 9, 9a, 9b and 9c, the soft water module 330 includes a module case 331 and soft water material filled in the module case 331. The inside of the module housing 331 is provided with a water flow path, the purified water is mixed with the soft water material when flowing through the water flow path, impurities such as calcium ions and magnesium ions in the purified water can be filtered by utilizing the characteristics of the soft water material, and the filtered purified water flows out of the module housing 331 and enters the water storage cavity of the water tank body.

In an embodiment, the module housing 331 has an overall outer contour that is approximately rectangular, including a lower shell 3311 and an upper cover 3312. Here, the lower case 3311 defines a space for accommodating soft water material, and the upper cover 3312 is detachably coupled to the lower case 3311. The detachable design can facilitate the user to replace soft water materials in the module housing 331.

And, the soft water module 330 further includes a water inlet pipe section 334, the water inlet pipe section 334 being located inside the lower housing 3311. One end of the water inlet pipe 334 is connected to the water outlet end of the water pipe 340, and the other end extends to the bottom of the module housing 331 from top to bottom. The water inlet pipe 334 is used for guiding the purified water from the water pipe 340 to the bottom of the module housing 331 so as to define a water flow path of 'upper water inlet and upper water outlet'. Here, the water inlet pipe section 334 has a space from the bottom of the module case 331 for water to flow out.

Here, the top end of the water inlet pipe section 334 abuts against the inner surface of the upper cover 3312. Therefore, a water leakage gap is not formed between the water inlet pipe section 334 and the upper cover 3312, so that the purified water can flow only along the water inlet pipe section 334 to the bottom of the housing 3311.

In some embodiments, the filtered water outlet 335 of the module housing 331 is formed through the top cover 3312, which is a path for purified water to flow out of the module housing 331.

The water flow action of the purified water drives the soft water material to flow towards the filtered water outlet 335, so that the soft water material is prevented from separating from the module housing 331, and the filter plate 336 is additionally arranged in the embodiment, so that the effect of intercepting the soft water material can be achieved.

Here, the filter plate 336 has a plurality of filter holes having a smaller diameter than the particle diameter of the soft water material. The soft water material cannot pass through the filtering holes and is thus confined in the inner space of the module case 331.

In some alternative embodiments, the top surface of the module housing 331 is recessed with an overflow slot 337, the overflow slot 337 extending from the filtered water outlet 335 toward the tank body to the top surface periphery. In the embodiment shown in fig. 9c, the overflow groove 337 is formed on the upper surface of the upper cover 3312, which can serve to guide the water flow direction, and particularly, the purified water flows from the overflow groove 337 to the tank body preferentially at the time of low water supply or just starting the water supply.

In some embodiments, the soft water module 330 is fixed to the inner wall of the tank body by a socket structure. The soft water module 330 can be quickly assembled and disassembled relative to the water tank body by utilizing the plug-in structure, so that soft water materials can be conveniently replaced.

In addition, in order to avoid the situation where the purified water inside the water containing tank 3212 submerges the soft water module 330, in the above-described embodiments, the vertical height of the filtered water outlet 335 of the module case 331 needs to be greater than the tank height of Rong Shuicao 3212. In this way, at least the filtered water outlet 335 is enabled to be always higher than the water level in Rong Shuicao 3212, so that the filtered water outlet 335 can be enabled to normally discharge water. Further, the water tank 3212 stores a large amount of sewage after long-term use, and the filtered water outlet 335 is provided at a high position, so that the problem of clogging of the filtered water outlet 335 due to dirt can be prevented.

Alternatively, the type of soft water material is soft water resin. Such as vinyl resins, meta-benzene resins, phenolic resins, and polyester resins. The application is not limited with respect to the particular type of soft water material selected.

Optionally, the first shell side 411, the second shell side 412 and the shell bottom 413 are integrally formed, thereby effectively ensuring structural strength and air tightness of the shell housing 410.

Here, the inside of the tube housing 410 defines a hollow air inlet cavity, and an air outlet 414 is provided at the top of the tube housing 410, a first air inlet 415 is provided at the first housing side 411, and a second air inlet 416 is provided at the second housing side 412.

In the embodiment, the pipe case 410 is disposed below the water washing purification unit 300 and is disposed to overlap with the water washing case 310 of the water washing purification unit 300. Here, the air outlet 414 formed at the top of the housing is referred to as an "air outlet end", which is in communication with the washing air inlet 3141 of the washing housing 310.

In this embodiment, the entire top of the tube housing 410 is opened as the air outlet 414, so as to ensure that the tube housing 410 has a sufficient air outlet area, and reduce the air outlet and exhaust resistance of the tube housing 410. In fig. 10a and 11, the air outlet 414 is defined as a semicircular range defined by the top edges of the first shell side 411 and the second shell side 412.

Alternatively, the outer contour of the washing housing 310 in the foregoing embodiment has a structure in which the front side is approximately rectangular and the rear side is approximately semicircular, so that the practical range of the washing air inlet 3141 formed at the bottom of the washing housing 310 includes a rectangular air inlet area at the front and a semicircular air inlet area at the rear. The relative arrangement of the tube housing 410 in the embodiment of the present disclosure corresponds to the rear portion of the washing housing 310, and thus the air outlet 414 of the tube housing 410 is configured to perform air flow transportation corresponding to the semicircular air inlet area of the washing housing 310.

In order to avoid the air leaking out of the rectangular air inlet area of the water washing air inlet 3141, in an alternative embodiment, the casing 410 further includes a front shroud 421, where the front shroud 421 is a plate body with a shape adapted to the rectangular air inlet area, and is formed by extending horizontally and forwardly from the top edge of the first casing side 411, and the front shroud 421 may be used to seal the rectangular air inlet area of the water washing air inlet 3141.

In an embodiment, one of the first air inlet 415 and the second air inlet 416 is an indoor air return, and the other is a fresh air inlet. In this embodiment, the first air inlet 415 is used as an indoor air return, i.e. corresponds to the indoor air inlet end in the foregoing. The second air inlet 416 serves as a fresh air inlet, i.e., corresponds to the "outdoor air inlet" described above.

Here, the first air inlet 415 is opened on the first case side 411. Optionally, the first air inlet 415 is configured in a rectangular, circular, triangular, trapezoid, or other shape, which is not limited in this application.

In an embodiment, the air inlet switching part 400 further includes a fresh air duct 450, wherein one end of the fresh air duct 450 is connected to the outdoor side, and the other end is connected to the second air inlet 416, so as to introduce the outdoor fresh air into the duct housing 410.

In some alternative embodiments, the switching guide 431 is pivoted in the air intake cavity of the tube housing 410, and it switches between different induced air modes by rotating. Here, the switching guide 431 may switch between at least the first air guiding state and the second air guiding state; in the first air guiding state, the air outlet 414 is communicated with the first air inlet 415 and seals the second air inlet 416, as shown in fig. 12 a. In the second air guiding state, the air outlet 414 is communicated with the second air inlet 416 and seals the first air inlet 415, as shown in fig. 12 b. That is, in the foregoing embodiment, when the switching guide 431 is in the first air guiding state, the air path switching mechanism is communicated with the indoor side for introducing indoor return air; when the switch guide 431 is in the second air guiding state, the air path switch mechanism is communicated with the outdoor side for introducing outdoor fresh air. The arrows in the figure show the airflow directions corresponding to the respective wind guiding states.

In an embodiment, as shown in fig. 13, the wind path switching mechanism further includes a pivot shaft 432 and a driver 433, and the driver 433 is in driving connection with the switching guide 431 through the pivot shaft 432, so as to controllably drive the switching guide 431 to switch between the first wind guiding state and the second wind guiding state.

In some embodiments, the pivot shaft 432 is disposed at a bottom edge of the first air inlet 415 or the second air inlet 416 and is formed by extending longitudinally along the bottom edge. In the embodiment shown in fig. 10a, the pivot shaft 432 is disposed at the bottom edge of the first air inlet 415, and the pivot shaft 432 is fixedly connected to the bottom edge of the switch guide 431, so that the switch guide 431 can rotate synchronously with the pivot shaft 432. Here, the wall of the tube housing 410 is provided with a through hole through which the pivot shaft 432 penetrates into the air intake chamber.

In the present embodiment, the switching guide 431 can flip up and down around the pivot shaft 432, so as to switch between the first air guiding state and the second air guiding state. When the switching guide plate 431 is turned down to a state of being attached to the wind guiding eyebrow 422, the wind path switching mechanism is in a first wind guiding state; when the switching guide 431 is turned up to a state of being attached to the first case side 411, the air path switching mechanism is in the second air guiding state.

And, the driver 433 includes a driving motor disposed at one end of the bottom edge of the first air inlet 415 or the second air inlet 416. For example, in the foregoing embodiment, the pivot shaft 432 is disposed on the bottom edge of the first air inlet 415, and the driving motor is correspondingly disposed at one end of the bottom edge of the first air inlet 415 and is in driving connection with the corresponding end of the pivot shaft 432.

Optionally, the driving motor is screwed and fixed on the wall of the tube housing 410, so as to facilitate disassembly and assembly.

Optionally, in this embodiment, referring to fig. 11, the tube housing 410 further includes an air guiding eyebrow 422, where the air guiding eyebrow 422 extends from the second housing side 412 to the first housing side 411, and the air guiding eyebrow 422 can enclose with the rest of the tube housing 410 (including the second housing side 412 and the housing bottom 413) to form a cavity channel corresponding to the second air inlet 416. In the first air guiding state, the switching guide plate 431 is overlapped with the air guiding eyebrow 422 to seal the cavity channel.

In an embodiment, the wind-guiding eyebrow 422 includes a cross plate surface 4221 and a sloping plate surface 4222. Wherein the cross plate 4221 extends from the upper edge of the second air inlet 416 toward the first case side 411, and the inclined plate 4222 extends from the outer edge of the cross plate 4221 obliquely downward toward the first case side 411. Here, the space between the inclined plate 4222 and the bottom of the casing 410 is configured as an air outlet end face of the cavity channel, through which the air flow may continue upward to the air outlet 414 at the top of the casing 410.

In further embodiments, not shown in the drawings, the first shell side 411 and the second shell side 412 are disposed adjacent. For example, the overall outer contour of the tube housing 410 is rectangular, and the first shell side 411 and the second shell side 412 are two adjacent shell sides that perpendicularly intersect. Here, the pivot shaft 432 is provided at the intersecting edge of the first case side 411 and the second case side 412, and is formed extending longitudinally along the intersecting edge, that is, in the present embodiment, the axial direction of the pivot shaft 432 is provided parallel to the vertical direction.

In the present embodiment, the switching guide 431 may be turned left and right about the pivot shaft 432, so as to switch between the first air guiding state and the second air guiding state.

And, a driving motor as the driver 433 is provided at one end of the intersecting edge of the first case side 411 and the second case side 412, for example, at the top end or bottom end position of the intersecting edge in the present embodiment.

In some alternative embodiments, the air path switching mechanism further includes a purification cartridge 440, the purification cartridge 440 being for filtering and purifying air flowing through the duct housing 410.
