Wherein, a valve cavity 40 is formed in the valve body 41, a port at one end of the valve cavity 40 is a steam inlet 312, a port at the other end of the valve cavity 40 is a steam outlet 311, that is, steam in the clean water tank 31 enters the valve cavity 40 through the steam inlet 312 and then enters the liner 12 through the steam outlet 311. Of course, a steam pipe may be disposed between the steam outlet 311 and the inner container 12.

A mounting plate 44 is provided within the valve chamber 20, i.e., the mounting plate 44 is fixedly connected to a portion of the side wall of the valve chamber 40. The mounting plate 44 is provided with a mounting hole 411 such that the first end of the spool 42 is pierced in the mounting hole 411, and the spool 42 is slidable in the axial direction of the mounting hole 411. In order for steam to pass from the steam inlet 312 to the steam outlet 311 through the valve chamber 40, the mounting plate 44 cannot seal off the valve chamber 40. That is, the mounting plate 44 is spaced from the side wall of the valve chamber 40, or a vapor passage 442 is provided in the mounting plate 44.

Alternatively, referring to fig. 8, the mounting plate 44 divides the valve chamber 40 into the exhaust chamber 402 and the mounting chamber 401 for mounting the valve core 42 and the elastic member 43, that is, the circumferential side surface of the mounting plate 44 is fixedly connected with the sidewall of the valve chamber 40 without any gap, which is advantageous for improving the reliability and stability of the mounting plate 44. At this time, the mounting plate 44 is provided with a steam through hole 442 communicating the steam outlet cavity 402 with the mounting cavity 401; one end of the steam outlet cavity 402 is provided with a steam outlet 311, and one end of the installation cavity 401 is provided with a steam inlet 312. At this time, steam enters the installation cavity 401 through the steam inlet 312, then enters the steam outlet cavity 402 through the steam through holes 442, and steam in the steam outlet cavity 402 enters the liner 12 through the steam outlet 311.

The through-air holes 442 are through holes penetrating the thickness direction of the mounting board 44, and may be through holes of any shape. Optionally, the via 442 is a circular through hole, and the processing is simple and convenient. In some specific embodiments, a plurality of through-holes 442 are provided, and the plurality of through-holes 442 are spaced apart along the circumference of the mounting hole 441, which is advantageous for improving the rate of steam passing. The present invention does not limit the number of the via holes 442.

The elastic member 43 may be a rubber sleeve, and the elastic member 43 may also be a spring, and in this embodiment, the elastic member 43 is a metal spring, which can withstand high-temperature steam, and is beneficial to prolonging the service life of the elastic member 43. The elastic member 43 is sleeved on the outer side of the valve core 42, the first end of the elastic member 43 is abutted against the mounting plate 44, and the second end of the elastic member 43 is abutted against the second end of the valve core 42, so that the valve core 42 is abutted against the steam inlet 312 under the action of elastic force of the elastic member 43 to seal the steam inlet 312. When the steam pressure in the clean water tank 31 is lower than the elastic force of the elastic piece 43, the valve core 42 is propped against the steam inlet 312 to seal the steam inlet 312, and the steam in the clean water tank 31 cannot enter the inner container 12 through the valve cavity 40 and the steam outlet 311.

When the vapor pressure in the clean water tank 31 is higher than the preset pressure value, the vapor pressure in the clean water tank 31 is greater than the elastic force of the elastic member 43, and the vapor pressure pushes the valve core 42 to move toward the installation hole 441, thereby opening the steam inlet 312, at this time, the vapor in the clean water tank 31 enters the valve cavity 40 through the steam inlet 312 and then enters the inner container 12 through the vapor outlet 311.

By the above arrangement, the pressure valve 3 is opened or closed by the steam in the clean water tank 31, which is simple and reliable; and the electric control is not needed, so that the structure of the clothes care machine is simplified, and the cost is reduced.

With continued reference to fig. 8, the valve core 42 includes a mounting post 421 and a blocking head 422 disposed at one end of the mounting post 421, and the other end of the mounting post 421 is disposed in the mounting hole 441 in a penetrating manner; one end of the blocking head 422 forms an abutment surface against the elastic member 43, and the other end of the blocking head 422 abuts against the steam inlet 312.

The mounting posts 421 may be cylinders, prisms, etc., and the mounting holes 441 are matched with the mounting posts 421. When the mounting posts 421 are prismatic, rotation of the mounting posts 421 relative to the mounting holes 441 is prevented. One end of the mounting column 421 is provided with a blocking head 422, and the cross-sectional area of the blocking head 422 is larger than that of the mounting column 421, so that an abutting surface is formed at the end, connected with the mounting column 421, of the blocking head 422, and the abutting surface abuts against the elastic piece 43. The other end of the blocking head 422 is an arc surface protruding towards the steam inlet 312, so that the steam inlet 312 is conveniently blocked by abutting. Optionally, the mounting post 421 and the plugging head 422 are integrally formed, so that the processing is convenient, and the structural strength is high.

In other embodiments, valve body 41 is integrally formed as a single piece with lid 314. Specifically, case lid 314 includes inner lid 3141 and outer lid 3142 that are disposed at an upper and lower interval, and thus, the structural strength of case lid 314 is advantageously improved, and heat preservation is facilitated. The outer cap 3142 protrudes downward to form a valve housing 412, the inner cap 3141 protrudes upward to form a valve seat 411, and the valve seat 411 and the valve housing 412 are fixedly connected to form the valve body 41. When the inner cover 3141 and the outer cover 3142 are connected, the connection between the valve seat 411 and the valve housing 412 can be realized, which is advantageous to simplify the structures of the pressure valve 4 and the fresh water tank 31 and to improve the stability and sealing of the installation of the pressure valve 4.

In summary, the embodiment of the present invention installs the pressure valve 4 at the steam outlet 311 on the clean water tank 31 to pressurize the steam in the clean water tank 31, so that the steam is sprayed into the liner 12 under the pressure to form a high-speed steam flow, and the liner 12 is quickly filled, so that the steam can penetrate into the fabric tissue more deeply and sufficiently, the humidity of the clothes is uniform, and the deodorizing and shaping effects are improved; the pressure valve 4 of the embodiment of the invention is opened or closed by means of steam pressure, and has simple and reliable structure, no need of electric control and low cost.

The air supply port 123 can be arranged at the bottom of the inner container 12, so that cold air supplied by the air supply port 123 conveniently enters the hot air component through the air inlet 121 to be heated; the exhaust outlet 111 may be disposed at the top of the housing 11, so that the hot air has a high specific gravity and easily rises to the top of the liner 12, and thus the exhaust outlet is convenient for exhausting the exhaust, thereby improving the drying efficiency.

In addition, in order to increase the exhaust rate of the exhaust gas, referring to fig. 2 and 3, an exhaust fan 112 is installed in the exhaust duct to accelerate the exhaust efficiency of the exhaust gas, further improving the drying efficiency of the laundry.
