[0001] The utility model relates to the field of clothing processing equipment, in particular to a feeding device and clothing processing equipment. Background Art

[0002] At present, washing machines usually add detergent into the washing drum during the washing process to enhance the washing effect on the clothes. The detergent is passed into the washing drum and mixed with the washing water to form a detergent, and the clothes are soaked and washed. In order to make the detergent fully contact with the clothes, an atomizing nozzle is set at one end of the detergent delivery pipeline to atomize the detergent. In order to improve the atomization effect, a structure similar to a venturi tube is set in the detergent delivery pipeline to increase the gas content in the detergent in the detergent delivery pipeline, thereby increasing the number of bubbles formed by the detergent. However, the venturi tube structure will increase the internal pressure of the detergent delivery pipeline. A pressure relief valve needs to be set to protect the detergent delivery pipeline to prevent the pipeline from being damaged due to excessive pressure. When the pressure relief valve is opened to relieve pressure, the local pressure of the pressure relief valve is too high, and the high-speed flowing gas rubs against the pressure relief valve to produce howling, which affects the user experience.

DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] At present, washing machines usually add detergent into the washing drum during the washing process to enhance the washing effect on the clothes. The detergent is passed into the washing drum and mixed with the washing water to form a detergent, and the clothes are soaked and washed. In order to make the detergent fully contact with the clothes, an atomizing nozzle is set at one end of the detergent delivery pipeline to atomize the detergent. In order to improve the atomization effect, a structure similar to a venturi tube is set in the detergent delivery pipeline to increase the gas content in the detergent in the detergent delivery pipeline, thereby increasing the number of bubbles formed by the detergent. However, the venturi tube structure will increase the internal pressure of the detergent delivery pipeline. A pressure relief valve needs to be set to protect the detergent delivery pipeline to prevent the pipeline from being damaged due to excessive pressure. When the pressure relief valve is opened to relieve pressure, the local pressure of the pressure relief valve is too high, and the high-speed flowing gas rubs against the pressure relief valve to produce howling, which affects the user experience.

[0029] Reference below Figure 1-Figure 5 The delivery device 1 according to the embodiment of the present invention is described.

[0030] like Figure 1-Figure 5 As shown, according to the utility model, the delivery device 1 includes a component body 11 (delivery component body) and a pressure relief component 12, the component body 11 is the delivery component body, a fluid flow channel 111 is formed in the component body 11, and the pressure relief component 12 includes a valve body 121, a valve channel is formed on the valve body 121, and the valve channel can selectively connect the fluid flow channel 111 with the outside; wherein, a connecting channel is formed on the valve body 121, and the connecting channel can selectively connect the fluid flow channel 111 with the outside.

[0031] Specifically, the component body 11 is generally arranged in the clothing processing chamber inside the drum washing machine. The component body 11 can be used to put liquid detergent or solid detergent into the clothing processing chamber, and a fluid flow channel 111 is formed inside the component body 11. The detergent for washing clothes flows in the fluid flow channel 111 and can be sprayed onto the clothes through structures such as nozzles. In order to improve the spraying effect of the component body 11 on the detergent, a structure similar to a venturi tube is provided in the fluid flow channel 111 and can produce a venturi effect accordingly, thereby increasing the number of bubbles sprayed by the component body 11 and increasing the contact area between the detergent and the clothes, thereby improving the clothing washing effect. However, the venturi structure will cause excessive local pressure in the fluid flow channel 111, causing damage to the fluid flow channel 111. Therefore, a pressure relief component 12 is provided in the present application to relieve pressure in the fluid flow channel 111 to avoid excessive pressure in the fluid flow channel 111.

[0032] Among them, a valve channel is formed on the valve body 121, one end of the valve channel is connected to the fluid flow channel 111, and the other end of the valve channel is connected to the outside world. When the pressure in the fluid flow channel 111 is below a preset value, the valve channel is in a closed state. When the pressure in the fluid flow channel 111 exceeds the preset value, the high-pressure gas in the fluid flow channel 111 pushes the valve body 121 to open the valve channel to discharge the high-pressure gas in the fluid flow channel 111, thereby avoiding damage to the component body 11 caused by excessive pressure in the fluid flow channel 111.

[0033] A connecting channel is formed on the valve body 121, one end of the connecting channel is connected to the fluid flow channel 111, and the other end of the connecting channel is connected to the outside. After the valve body 121 is opened, the connecting channel connects the fluid flow channel 111 with the outside, thereby discharging the high-pressure gas in the fluid flow channel 111 to achieve pressure relief of the fluid flow channel 111, and the connecting channel can be arranged on the valve body 121 and spaced apart from the valve channel, one end of the connecting channel is connected to the fluid flow channel 111, and the other end of the connecting channel is connected to the outside, thereby connecting the fluid flow channel 111 with the outside through the connecting channel. When the pressure in the fluid flow channel 111 exceeds a preset value, the high-pressure gas in the fluid flow channel 111 can be discharged to the outside through the valve channel and the connecting channel, thereby increasing the flow area of ​​the gas, which is beneficial to reducing the gas flow speed, thereby eliminating the whistling noise generated by gas pressure relief and improving user experience.

[0034] According to the dispensing device 1 of the utility model, the efficiency of detergent spraying is improved by setting the component body 11 to provide a cleaning effect for clothes, and the pressure relief component 12 is set to relieve the pressure of the fluid flow channel 111 to prevent the fluid flow channel 111 from being damaged due to excessive pressure. A valve body 121 is set in the pressure relief component 12 to communicate with the fluid flow channel 111. When the pressure in the fluid flow channel 111 exceeds a preset value, the high-pressure gas in the fluid flow channel 111 pushes the valve channel to open, thereby connecting the fluid flow channel 111 with the outside through the valve channel, thereby achieving pressure relief of the fluid flow channel 111. A connecting channel is also set on the valve body 121, and the connecting channel connects the fluid flow channel 111 with the outside. When the pressure relief component 12 is relieving pressure, the gas can be discharged to the outside through the valve channel and the connecting channel at the same time, thereby increasing the gas flow area and reducing the gas flow speed, which is beneficial to eliminating the whistling noise generated during gas discharge and improving the user experience.

[0035] According to some embodiments of the present invention, the pressure relief assembly 12 further includes a valve core 122 movably disposed in the valve channel and adapted to move and open the valve channel after the pressure of the fluid channel 111 exceeds a preset value.

[0036] Specifically, a valve channel for accommodating a valve core 122 is formed on the valve body 121, one end of the valve channel is connected to the fluid flow channel 111, and the other end of the valve channel is connected to the outside world. When the pressure in the fluid flow channel 111 is below a preset value, the valve core 122 is fixed at the connection between the valve channel and the fluid flow channel 111 and closes the valve channel. When the pressure in the fluid flow channel 111 exceeds the preset value, the high-pressure gas in the fluid flow channel 111 pushes the valve core 122 to move along the extension direction of the valve channel and open the valve channel to discharge the high-pressure gas in the fluid flow channel 111, thereby avoiding damage to the cavity of the component body 11 caused by excessive pressure in the fluid flow channel 111.

[0037] According to some embodiments of the present invention, a pressure relief groove 13 located inside the valve channel is formed on the valve body 121 , and a bottom wall of the pressure relief groove 13 is spaced from the valve core 122 to form a communication channel.

[0038] like Figure 4 As shown, the pressure relief groove 13 is arranged on the inner wall of the valve channel and on the outer periphery of the valve core 122. The pressure relief groove 13 and the valve core 122 are spaced apart to facilitate the high-pressure gas to push the valve core 122 open, thereby connecting the fluid flow channel 111 with the connecting channel. The pressure relief groove 13 has a simple structure. After the high-pressure gas in the fluid flow channel 111 enters the connecting channel, the flow area of ​​the gas is increased and the flow rate of the gas is reduced, thereby eliminating the whistling noise generated by gas exhaust and improving the user experience.

[0039] According to some embodiments of the present invention, the depth of the pressure relief groove 13 gradually increases in a direction away from the component body 11 .

[0040] Specifically, the pressure relief groove 13 is inclined relative to the extension direction of the valve channel, and the bottom wall of the pressure relief groove 13 forms a guiding slope, which extends in the direction away from the fluid flow channel 111. When the high-pressure gas in the fluid flow channel 111 pushes the valve core 122 open and is discharged from the connecting channel through the pressure relief groove 13, the depth of the pressure relief groove 13 gradually increases in the direction away from the fluid flow channel 111, and the flow area of ​​the high-pressure gas when passing through the pressure relief groove 13 increases. Under the condition of the same gas flow rate, the smaller the gas flow area, the greater the gas flow speed, and the easier it is for the gas to rub against the valve body 121 and produce howling when discharged. Through the above-mentioned arrangement, the gas flow area is increased, which is beneficial to reducing the gas flow rate, so as to eliminate the howling caused by high-speed gas circulation and improve the user experience.

[0041] According to some embodiments of the present invention, the pressure relief grooves 13 are configured to be multiple and spaced apart in the circumferential direction of the valve channel.

[0042] Specifically, a plurality of pressure relief grooves 13 are arranged at intervals in the circumferential direction of the valve channel, and the arrangement of the pressure relief grooves 13 is more uniform. When the gas is depressurized, the gas is discharged through the plurality of pressure relief grooves 13, and the gas is discharged evenly, thereby avoiding the situation where excessive local pressure occurs during the pressure relief process, and ensuring that the gas pressure relief is more stable. In addition, by arranging a plurality of pressure relief grooves 13 at intervals in the circumferential direction of the valve channel, the flow area of ​​the gas can be increased, and the flow rate of the gas during pressure relief can be further reduced, thereby eliminating the whistling noise caused by the high-speed gas flow.

[0043] According to some embodiments of the present utility model, the valve channel includes a first channel section 141 and a second channel section 142 which are connected to each other, one end of the first channel section 141 is connected to the fluid flow channel 111, one end of the second channel section 142 is connected to the other end of the first channel section 141, and the other end of the second channel section 142 is connected to the outside; wherein the diameter of the first channel section 141 is smaller than the diameter of the second channel section 142 so that a step surface 143 is formed between the first channel section 141 and the second channel section 142, and the pressure relief groove 13 is arranged on the inner wall of the first channel section 141 and the pressure relief groove 13 extends to the step surface 143.

[0044] Specifically, one end of the first channel section 141 is connected to the fluid flow channel 111, and the gas discharged from the fluid flow channel 111 preferentially flows through the first channel section 141. A plurality of pressure relief grooves 13 are arranged at intervals on the circumferential direction of the inner wall of the first channel section 141. In the process of the gas passing through the first channel section 141, the plurality of pressure relief grooves 13 guide the gas and increase the gas flow area, thereby reducing the gas flow rate; one end of the second channel section 142 is connected to the first channel section 141, and the other end of the second channel section 142 is connected to the outside. The gas guided by the pressure relief grooves 13 flows into the second channel section 142 and is discharged to the outside through the second channel section 142, wherein The diameter of the second channel section 142 is greater than that of the first channel section 141, which further increases the flow area of ​​the gas, improves the gas deceleration effect, and eliminates the whistling noise generated by the gas. A step surface 143 is formed between the first channel section 141 and the second channel section 142, and at least part of the circumferential edge of the valve core 122 abuts against the step surface 143. When the pressure in the fluid flow channel 111 is below a preset value, the circumferential edge of the valve core 122 abuts against the step surface 143, and the step surface 143 supports the valve core 122. The first channel section 141 can be sealed by the cooperation between the valve core 122 and the step surface 143.

[0045] According to some embodiments of the present invention, the diameter of the first channel section 141 gradually increases toward the second channel section 142 .

[0046] like Figure 4As shown, the peripheral wall of the first channel section 141 is inclined toward the second channel section 142, and the wall thickness of the first channel section 141 gradually decreases in the direction away from the fluid flow channel 111, so that in the process of the gas discharged from the fluid flow channel 111 passing through the first channel section 141, the area of ​​gas circulation gradually increases, which is beneficial to improving the pressure relief efficiency. In addition, since the gas circulation area is large, it is beneficial to reduce the gas flow rate and eliminate the whistling noise generated by the gas circulation.

[0047] According to some embodiments of the present invention, a sealing ring 15 is sleeved on the outer periphery of the valve core 122 , and the sealing ring 15 is suitable for abutting against the inner wall of the first channel section 141 .

[0048] Specifically, when the pressure in the fluid flow channel 111 is lower than a preset value, at least part of the outer peripheral edge of the valve core 122 abuts against the step surface 143, and the sealing ring 15 is squeezed under the weight of the valve core 122 and abuts against the inner wall of the first channel section 141. The circumferential sides of the sealing ring 15 respectively abut against the inner walls of the valve core 122 and the first channel section 141 to seal the first channel section 141. Since the fluid flow channel 111 is connected to the first channel section 141, the sealing ring 15 seals the first channel section 141, thereby ensuring the sealing of the fluid flow channel 111 and avoiding air leakage when the medium is added, which affects the addition efficiency.

[0049] According to some embodiments of the present invention, the pressure relief valve 1 further includes an elastic member 16 , and the elastic member 16 is disposed at an end of the valve core 122 away from the first channel section 141 .

[0050] Specifically, an installation groove may be formed at one end of the valve core 122 away from the fluid flow channel 111, a connecting column is arranged in the installation groove, an elastic member 16 is sleeved on the outer periphery of the connecting column and arranged in the installation groove, one end of the elastic member 16 is connected to one end of the valve core 122 away from the first channel section 141, an end cover may be arranged at one end of the valve channel away from the fluid flow channel 111, and the other end of the elastic member 16 may be connected to the end cover, when the pressure in the fluid flow channel 111 is below a preset value, the valve core 122 is pushed to squeeze the seal under the elastic effect of the elastic member 16 and the influence of the gravity of the valve core 122 itself. The sealing ring 15 abuts against the peripheral wall of the first channel section 141 to close the first channel section 141; when the pressure in the fluid flow channel 111 is higher than the preset value, the high-pressure gas in the medium accommodating chamber pushes the valve core 122 to move away from the fluid flow channel 111 along the extension direction of the valve channel to connect the fluid flow channel 111 with the outside, and the high-pressure gas is discharged to the outside through the first channel section 141 and the second channel section 142 in sequence. When the high-pressure gas is depressurized, the valve core 122 is reset under the action of the elastic member 16 and its own gravity, and the first channel section 141 is sealed again to ensure the medium delivery efficiency.

[0051] In summary, the dispensing device 1 according to the utility model includes a component body 11, a fluid flow channel 111 is formed in the component body 11, and the detergent for washing clothes flows in the fluid flow channel 111 and is sprayed onto the clothes through the component body 11, thereby improving the cleaning effect of the clothes. In order to avoid excessive pressure in the fluid flow channel 111, a pressure relief component 12 is provided to relieve the pressure of the fluid flow channel 111, a valve channel is formed in the valve body 121, and a valve core 122 is movably arranged in the valve channel, and the valve channel is connected to the fluid flow channel 111. When the pressure in the fluid flow channel 111 exceeds a preset value, the high-pressure gas in the fluid flow channel 111 pushes the valve core 122 to move and connects the fluid flow channel 111 to the outside. The gas is discharged from the valve channel, and a connecting channel is also formed on the valve body 121. The connecting channel connects the fluid flow channel 111 with the outside. When the gas is depressurized, the discharged gas can be discharged through the valve channel and the connecting channel to increase the gas flow area, thereby reducing the gas flow rate and eliminating the whistling caused by gas discharge; a pressure relief groove 13 is arranged in the valve channel, and the depth of the pressure relief groove 13 gradually increases in the direction away from the fluid flow channel 111, and the pressure relief groove 13 is constructed to be a plurality of pressure relief grooves 13 arranged at intervals in the circumferential direction of the valve channel to increase the gas flow area. Under the condition of the same flow rate, the gas flow area is larger and the flow rate is smaller, which is conducive to eliminating the whistling noise generated by the gas and improving the user experience.

[0052] Among them, the valve channel includes a first channel section 141 and a second channel section 142 which are connected to each other. A pressure relief groove 13 is arranged in the first channel section 141. The diameter of the first channel section 141 is smaller than the diameter of the second channel section 142, which further increases the gas flow area and is conducive to eliminating the howling caused by gas discharge. A sealing ring 15 is sleeved on the outer periphery of the valve core 122 to ensure the sealing of the first channel section 141; an elastic member 16 is arranged at one end of the valve core 122 away from the first channel section 141 to push the valve core 122 to reset after the pressure relief is completed.
