TECHNICAL FIELD
[0001] The utility model relates to water storage device field, concretely is a water storage tank and the clothes dryer with the water storage tank. BACKGROUND
[0002] For some domestic appliances that need to add water in use, for example, garment steamer, clothes dryer etc., a water storage tank is built in the domestic appliance to store water. Taking the clothes dryer as an example, the water in the water storage tank can be sprayed into the drum through the internal pipeline to care for the clothes.
[0003] The existing clothes dryer has a filter opening and a vent hole arranged side by side in the water inlet of the water storage tank, the filter opening and the vent hole are both in communication with the water storage part, the top of the vent hole is higher than the filter screen surface of the filter opening, the vent hole can exhaust during water adding to keep the air pressure balance inside and outside the water storage tank and ensure that the water can flow into the water storage part normally.
[0004] However, the area of the water inlet of the water storage tank is limited, the separately arranged vent hole will occupy a large area of the water inlet, so that the area of the filter opening is small, affecting the water filtering efficiency. In addition, when water is added to the water inlet of the water storage tank through the guide water channel, there is a risk of misplacing the water into the vent hole, which will cause the vent hole to fail and the air pressure in the water storage tank to rise. SUMMARY
[0005] In view of the above problems, the utility model provides a water storage tank without a separately arranged vent hole and a clothes dryer with the water storage tank.
[0006] On the one hand, the utility model provides a water storage tank, which comprises a tank body and a filter device. The side wall of the tank body is provided with a water inlet, and the filter device is arranged at the water inlet. The filter device comprises a plurality of filter units, and the plurality of filter units enclose a concave water filtering area. In particular, at least one filter unit of the side wall of the water filtering area is formed into a side wall filter screen, and the highest liquid storage height of the tank body is lower than the upper edge of the side wall filter screen.
[0007] According to the technical scheme of the utility model, when water is added to the water inlet of the water storage tank, since the highest liquid storage height of the tank body is lower than the upper edge of the side wall filter screen, there is always an area above the side wall filter screen that is not submerged by water, so that the side wall filter screen can realize water filtering and ventilation at the same time. That is, without a separately arranged vent hole, the water filtering area can be effectively increased and the water filtering efficiency can be improved under the condition that the area of the water inlet is limited. Moreover, even if water splashes onto the ventilation area above the side wall filter screen, the water can quickly flow down through the side wall filter screen without causing blockage, so that the air pressure balance inside and outside the water storage tank can be ensured.
[0008] It should be noted that the "maximum liquid storage height of the tank" in the utility model refers to the liquid level in the tank when the maximum liquid storage capacity is reached, at this time, even if the liquid is filled into the tank, the liquid level cannot be raised. For example, for the case where the water inlet is arranged at the top of the side wall of the water storage tank or extends from the side wall of the water storage tank to above the water storage tank, the "maximum liquid storage height of the tank" refers to the liquid level when the tank is completely filled with liquid. Another example, for the case where the water inlet is arranged on the upper part of the side wall of the water storage tank, the opening height of the water inlet is the maximum liquid storage height of the tank.
[0009] As a preferred technical solution, at least one filter unit of the bottom wall of the water filtering area is formed as a bottom wall filter screen.
[0010] According to the preferred technical solution, when water is added to the water inlet of the water storage tank, the side wall filter screen and the bottom wall filter screen of the water filtering area can filter water, increasing the water filtering area and improving the water filtering efficiency.
[0011] As a preferred technical solution, the side wall filter screen is inclined, so that the cross-sectional area of the water filtering area gradually decreases from top to bottom.
[0012] According to the preferred technical solution, since the filter screen has a certain water resistance, when the amount of water added is relatively large, water often accumulates in the water filtering area. By inclining the side wall filter screen, as the water level in the water filtering area rises, the water filtering area below the water body also increases, that is, the water filtering speed also increases, thereby increasing the water filtering efficiency and improving the water accumulation in the water filtering area.
[0013] As a preferred technical solution, the water storage tank further comprises a water guide shell fixed to the side wall of the tank corresponding to the water inlet, the water guide shell is concave with a top opening, and one side is in communication with the inside of the tank.
[0014] According to the preferred technical solution, the filter device can be directly placed at the top opening of the water guide shell, so that the water filtered by the filter unit of the filter device will be collected and guided to the water inlet by the water guide shell, on the one hand, ensuring complete collection of the filtered water, and on the other hand, the wall surface not directly corresponding to the water inlet of the filter device can also be formed as a filter unit, improving the water filtering efficiency.
[0015] As a preferred technical solution, the side wall filter screen with an upper edge higher than the maximum liquid storage height of the tank is arranged on the side of the filter device close to the inside of the tank.
[0016] According to the preferred technical solution, the side wall filter screen is directly arranged on the side close to the inside of the tank, so that the inside of the tank can be directly in communication with the outside atmosphere through the area above the side wall filter screen which is not submerged, for gas exchange, maintaining the pressure balance between the inside of the tank and the outside atmosphere.
[0017] As a preferred technical scheme, the water storage tank further comprises a clamping member formed by downward extension of the rim of the filtering device, and a clamping slot is formed between the clamping member and the outer surface of the filtering device, and the clamping slot is clamped to the top outer edge of the water guide shell.
[0018] According to the preferred technical scheme, the filtering device only needs to be placed at the top opening of the water guide shell, and reliable fixed installation can be completed in cooperation with the top outer edge of the water guide shell, which facilitates subsequent cleaning and replacement of the filtering device.
[0019] As a preferred technical scheme, the filtering device is fixed in the water guide shell in a manner of completely covering the top opening of the water guide shell.
[0020] According to the preferred technical scheme, on the one hand, complete filtration of water entering the tank can be ensured, and on the other hand, the water filtration area can be maximized to improve the water filtration efficiency.
[0021] As a preferred technical scheme, the part of the filtering device arranged towards the side wall of the water guide shell is a baffle, and the baffle is arranged in abutment with the inner surface of the water guide shell.
[0022] According to the preferred technical scheme, the filtering device is formed by the baffle and the filtering unit in cooperation, which can improve the overall structural strength of the filtering device. And the abutment of the baffle with the inner surface of the water guide shell can further improve the installation stability of the filtering device and the water guide shell.
[0023] As a preferred technical scheme, the filtering unit is a filter screen or a perforated plate.

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0031] In the present application, unless otherwise explicitly specified and limited, "on" or "under" of a first feature to a second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, "on", "above" and "on" of the first feature to the second feature include that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. "Under", "below" and "under" of the first feature to the second feature include that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.
[0032] In the present application, the term "the highest liquid storage height of the box" refers to the liquid level in the box when the maximum liquid storage capacity is reached, at which time the liquid level cannot be raised even if the liquid is further filled into the box. For example, for the case that the water inlet is arranged at the top of the side wall of the water storage tank or extends from the side wall of the water storage tank to be higher than the water storage tank, the "the highest liquid storage height of the box" refers to the liquid level when the liquid completely fills the box. For another example, for the case that the water inlet is arranged on the upper part of the side wall of the water storage tank, the opening height of the water inlet is the highest liquid storage height of the box.
[0033] First embodiment
[0034] Figure 1 It is a schematic diagram of the overall structure of a water storage tank provided by an embodiment of the present application. Figure 2 It is a schematic diagram of the cross-sectional structure of a water storage tank provided by an embodiment of the present application. In combination with Figure 1 and Figure 2 , the water storage tank comprises a box 1 and a filter device 2.
[0035] The box 1 can be a water storage box of any household appliance that needs to add water or store water, such as a clothes dryer, a garment steamer, a humidifier, a water purifier, etc., and is not limited herein. The sidewall of the box 1 is provided with a water inlet 11, and the water inlet 11 is provided with a filter device 2. A user can add water to the water storage tank through the water inlet 11.
[0036] The filter device 2 comprises a plurality of filter units 21, which can be any filter structure capable of filtering impurities in water, such as a filter screen, a perforated plate, etc. In addition, the area and shape of the filter unit 21 are not limited herein and can be formed as an entire wall of the filter device 2 or as a component block on any sidewall.
[0037] The plurality of filter units 21 of the filter device 2 are enclosed to form a concave structure, and the inside of the concave structure is used to store and filter water, i.e., a filter water area 20. In particular, at least one filter unit 21 of the sidewall of the filter water area 20 is formed as a sidewall filter screen 211, and the highest liquid storage height of the box 1 is lower than the upper edge of the sidewall filter screen 211. Therefore, when water is added to the water inlet 11 of the water storage tank, there will always be an area above the sidewall filter screen 211 (hereinafter referred to as a ventilation area) that is not submerged by water, so that the box 1 can be in communication with the outside atmosphere through the ventilation area, so that the air pressure inside the box 1 is balanced with the outside atmospheric pressure.
[0038] Compared with the existing water storage tank that separately provides a ventilation port at the water inlet 11, the water storage tank provided by the present embodiment integrates the functions of ventilation and filtration on the sidewall filter screen 211. On the one hand, in the case of limited area of the water inlet 11, it is not necessary to separately provide a ventilation port, which can effectively increase the filter water area and improve the filter water efficiency. On the other hand, even if water splashes onto the ventilation area above the sidewall filter screen 211, it can quickly flow down through the sidewall filter screen 211 without causing blockage of the ventilation area, thereby ensuring the air pressure balance inside and outside the water storage tank.
[0039] It should be noted that the plurality of filter units 21 enclose the concave filter water area 20, which means that the concave filter water area 20 is surrounded by the plurality of filter units 21, and is not limited to being enclosed by the filter units 21 only. As shown in the drawings, the filter water area 20 can also be enclosed by the plurality of filter units 21 and the baffles 22 without filtration function. Those skilled in the art can understand that the alternative technical solutions formed by simple adjustment of the number and position of the filter units 21 also belong to the protection scope of the present utility model.
[0040] Second embodiment
[0041] Figure 3This is a schematic diagram of the structure of a water storage tank filtration device 2 provided in this embodiment. The specific structure of the water storage tank filtration device 2 provided in this embodiment will be further described in detail below with reference to the accompanying drawings.
[0042] like Figure 3 As shown, at least one filter unit 21 on the side wall of the filter device 2 is a side wall filter screen 211, and at least one filter unit 21 on the bottom wall of the filter device 2 is a bottom wall filter screen 212. When water is added to the water inlet 11, both the side wall filter screen 211 and the bottom wall filter screen 212 of the water filtration zone 20 can filter water, increasing the filtration area and improving the filtration efficiency.
[0043] For example, the side wall of the filter device 2 near the water inlet 11 can be formed as a side wall filter 211, and the bottom wall of the filter device 2 can also be formed as a bottom wall filter 212. This can further increase the filtration area, and the water filtered by the side wall filter 211 facing the water inlet 11 can flow directly into the tank, thereby maximizing the filtration efficiency of the filter device 2.
[0044] Combination Figure 2 and Figure 3 Furthermore, preferably, the sidewall filter screen 211 of the filter device 2 can be inclined, so that the cross-sectional area of the filtration zone 20 gradually decreases from top to bottom. Since the filter screen and other filtration units 21 have a certain water resistance, the water level in the filtration zone 20 will rise after a large amount of water enters. At this time, due to gravity, the filter screen located below the water in the filtration zone 20 will have a higher filtration efficiency. Therefore, by inclinedly setting the sidewall filter screen 211, as the water level in the filtration zone 20 rises, the filtration area below the water also increases, that is, the filtration speed also increases, thereby increasing the filtration efficiency and improving the water accumulation situation in the filtration zone 20.
[0045] In this embodiment, the distribution and arrangement of the filter units 21 of the filter device 2 are designed in more detail, which effectively increases the filtration area of the filtration zone 20 and further improves the filtration efficiency of the filter device 2.
[0046] Third embodiment
[0047] In the third embodiment of this utility model, a water storage tank with a water-conducting outer shell 3 is provided. Other undescribed structures are the same as those in the first or second embodiment and will not be described in detail here.

Figure 1 and Figure 4As can be seen, the water guide shell 3 is formed as a concave shape opening at the top of the side wall of the box body 1, and one side of the concave water guide shell 3 corresponds to the water inlet 11, so that the inside of the concave water guide shell 3 is in communication with the inside of the box body 1.
[0049] In the above manner, the filter device 2 can be directly placed at the top opening of the water guide shell 3, so that the water filtered by the filter unit 21 of the filter device 2 will be collected and guided by the water guide shell 3 to the water inlet 11, which on the one hand ensures the complete collection of the filtered water, and on the other hand, the wall surface of the filter device 2 which does not directly correspond to the water inlet 11 can also be formed as a filter unit 21, thereby improving the water filtering efficiency.
[0050] Preferably, in order to further ensure the complete filtration of the water entering the box body 1 and maximize the water filtering area of the filter device 2, the filter device 2 can be fixed in the water guide shell 3 in a manner that completely covers the top opening of the water guide shell 3, so that the external water must pass through the filter device 2 before entering the water guide shell 3 to reach the water inlet 11.
[0051] In combination with Figure 2 and Figure 4 As can be seen, the side wall of the filter device 2 near the inside of the box body 1 is formed as a side wall filter screen 211 with an upper edge higher than the highest liquid level of the box body 1. The side wall filter screen 211 is directly arranged near the inside of the box body 1, so that the inside of the box body 1 can be in direct communication with the outside atmosphere through the air exchange area at the upper part of the side wall filter screen 211 for gas exchange, thereby maintaining the air pressure balance between the inside of the box body 1 and the outside atmosphere.
[0052] Further preferably, the filter device 2 can be formed by the baffle 22 and the filter unit 21 together. Specifically, the part of the filter device 2 towards the water inlet 11 can be arranged as the filter unit 21, the part of the filter device 2 towards the side wall of the water guide shell 3 can be arranged as the baffle 22, and the baffle 22 can be arranged in close contact with the inner surface of the water guide shell 3, thereby improving the overall structural strength of the filter device 2 and the installation stability of the filter device 2 and the water guide shell 3.
[0053] In some embodiments, the filter device 2 can be directly placed at the top opening of the water guide shell 3, or the filter device 2 can be provided with a magnetic attraction structure corresponding to the water guide shell 3 for assembly. In another preferred embodiment, the filter device 2 can be provided with a lapping piece 4 extending downward from the edge of the filter device 2, and a lapping clamping groove 40 is formed between the lapping piece 4 and the outer surface of the filter device 2, which lapping clamping groove 40 lappingly engages the top outer edge of the water guide shell 3.
[0054] The filter device 2 is fixed by the overlap piece 4 on the side far away from the water inlet 11, and the overlap piece 4 is further fixed on the side far away from the water inlet 11 in cooperation with the side wall filter screen 211. However, the utility model is not limited thereto, and the overlap piece 4 arranged on the two sides adjacent to the water inlet 11 of the filter device 2 is also applicable to the technical scheme of the utility model.
[0055] In some other embodiments of the utility model, a clothes dryer is also provided, which has the water storage tank in any of the above embodiments, and water in the water storage tank can be sprayed onto the surface of clothes in the drum of the clothes dryer through the guide water pipe to care for the clothes.
[0056] The above are only the preferred embodiments of the utility model, and are not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
