Description

TECHNICAL FIELD The present invention belongs to the field of washing machines, and more particularly, to a water supply device for washing machines and a washing machine.

As the standard of living continues to improve, more and more families are soaking in a bathtub when taking a bath. However, if the water in the bathtub is drained as it is after bathing, it is very wasteful. Also, as water resources are becoming increasingly scarce, recycling of wastewater seems particularly important. On the other hand, washing machines are widely used in many households, and the amount of water used by washing machines accounts for a considerable portion of domestic water. Therefore, it is a matter of great concern for people how to link these to make full use of water. In Japan, leftover bath water has been used for washing clothes since the 1990s, and a washing machine capable of washing clothes with leftover bath water has been developed. Since the washing machine using the remaining hot water from the bath can reuse domestic water, the amount of water used by the washing machine can be greatly reduced.

In addition, a normal washing/drying machine can wash the clothes put into the washing tub and, after washing is completed, can dry the clothes based on the selected program. In the drying process, the action of the heating device heats the dry air in the heating tube to form dry hot air. By introducing this into the washing tank and generating heat exchange with the wet clothes in the washing tank, the water in the clothes is removed and slightly moist hot air is formed. This hot, semi-moist air enters the condensing assembly through an outlet located in the wash tank, and the condensing action of the assembly causes the moisture in the hot, semi-moist air to condense into water. As it exits the drain pipe, the condensed air becomes relatively dry and cool. This air is reintroduced into the heating tube by the action of the fan, where it is heated to become dry and hot air for the next cycle. This is repeated until the drying program ends.

In the process of washing and drying clothes, it is inevitable that a lot of fluff and other foreign substances (hereinafter referred to as fluff) are generated. The fluff directly enters the water supply channel from the water supply port together with the moist and hot air, and not only contaminates the water supply channel, but also increases the cleaning cost of the water supply channel of the washing machine. Moreover, in serious cases, there is a risk of clogging the water supply route.

In view of the above, the present invention is proposed.

The present invention is a water supply device for a washing machine and a washing machine that eliminates the defects of the prior art and connects the washing tub and the water supply path only when water is supplied, and shuts off the water supply path and the washing tub when a program such as drying is executed. is a technical problem to be solved by providing This avoids the problems of heat loss during the drying process and the ingress of contaminants such as lint into the water supply path. Also, the water supply device of the present invention receives washing water supplied from different water supply routes. In addition, by connecting the main water supply and the water suction pump in parallel using the flow path in the flow distribution chamber of the tank, there is no need for a conventional water supply valve independently installed for the water suction pump. The present invention has advantages such as fewer parts, lower cost, and smaller occupied volume than a washing machine equipped with a water suction pump. This makes it easier for the washing machine to use another water source, such as leftover hot water from a bath, as washing water for the washing machine, thereby achieving the purpose of saving the amount of water used.

To achieve the above objects, the present invention employs the following technical solutions.

Furthermore, the washing machine is provided with a drying module communicating with the washing tub. The drying module is used for drying clothes. The one-way communication device is used to prevent air in the washing tub from entering the water supply path of the washing machine when drying clothes.

Further, the tank includes a flow distribution chamber and a mixing chamber which are in communication with each other. A channel for guiding the direction of water flow is provided in the channel distribution chamber, and the tank spout is provided in the water mixing chamber.

Further, the water supply device of the washing machine includes a first water supply path and a second water supply path that communicate with the tank and can supply water individually. The first water supply path includes a water suction pump, and the flow path distribution chamber is provided with a first flow path that communicates the second water supply path and the pump chamber of the water suction pump.

Further, the channel distribution chamber has a first water supply end and a first water discharge end respectively communicating with the first channel. The first water supply end communicates with the second water supply path, and the first water discharge end communicates with the pump chamber of the water suction pump. The installation height of the first water supply end of the channel distribution chamber is lower than the installation height of the first water discharge end. Preferably, the first water supply end and the first water discharge end are provided on opposite sides of the channel distribution chamber, respectively, and the first channel crosses the channel distribution chamber.

Furthermore, a second channel is further provided in the channel distribution chamber. The channel distribution chamber has a second water supply end and a second water discharge end respectively communicating with the second channel. The second water supply end communicates with the first channel, and the second water discharge end communicates with the water mixing chamber.

Further, in the flow distribution chamber, there is further provided a third flow path that guides the water in the water suction pump to flow into the tank and communicates with the drain port of the water suction pump. The channel distribution chamber has a third water supply end and a third water discharge end respectively communicating with the third channel. The third water supply end communicates with the water outlet of the water suction pump, and the third water discharge end of the third channel communicates with the water mixing chamber.

A washing machine to which any one of the water supply devices described above is applied, wherein a one-way communication device is provided in the water supply path of the washing machine. The one-way communication device is opened under water pressure when water is supplied to the washing machine, and remains closed after water supply is completed.

By using the above technical solutions, the present invention has the following beneficial effects compared with the prior art.

In the water supply device for the washing machine and the washing machine according to the present invention, the one-way communication device is provided in the water supply path of the washing machine. The one-way communication device is opened under water pressure when water is supplied to the washing machine, and remains closed after water supply is completed. The washing tank communicates with the water supply path only when water is supplied, and the water supply path and the washing tank are cut off when a program such as drying is executed. This avoids the problems of heat loss during the drying process and the ingress of contaminants such as lint into the water supply path.

The water supply device includes a tank that communicates with the water supply path, and the one-way communication device is provided at the water outlet of the tank of the washing machine. The tank communicates with a first water supply path and a second water supply path, which communicate with the washing tank and are capable of supplying water individually. The first water supply path includes a water suction pump, and the second water supply path communicates with the water suction pump. As a result, the main water suction and the water suction pump are connected in parallel, so that the water supply to the water supply path and the water supply to the pump chamber of the water suction pump, that is, the priming process is also realized. As a result, since the water suction pump can be started quickly after the water supply path is opened, the conventional independent water supply valve required for priming for starting the water suction pump is omitted. Therefore, compared with a conventional washing machine equipped with a water suction pump, the number of parts is reduced, the cost is reduced, and the occupied volume is reduced.

In order to achieve this object, the present invention provides a first channel in the tank for guiding the water flow to flow into the pump chamber of the water suction pump. The first flow path directly communicates with a water supply path independent of the water suction pump. Guidance by the priming water channel is realized by the arrangement of the flow channel in the tank, so that the cost of modifying a conventional washing machine can be reduced. Also, by replacing the tank, the washing machine can be quickly provided with a water absorption function by means of a water absorption pump.

In the present invention, the installation height of the first water supply end of the channel distribution chamber is lower than the installation height of the first water discharge end, and the first water supply end and the first water discharge end are respectively on opposite sides of the channel distribution chamber. The design is to complete priming of the pump by overflow from the tank. According to such a system, it is possible not only to extend the length of the water supply circuit, but also to provide an energy buffer area for the water supply. As a result, the impact of the water flow during water supply is reduced, and the fluidity after the water flow enters the tank is reduced, so that the water flow can be caused to flow more stably in the guiding direction of the channel.

A water mixing chamber is provided below the channel distribution chamber of the tank, and the water mixing chamber communicates with the washing tank. Also, the water mixing chamber and the channel distribution chamber communicate with each other through a plurality of openings. This ensures that the water streams from the different channels can finally join the mixing chamber and finally enter the washing tank through the opening of the mixing chamber that is open towards the washing tank. .

A one-way valve is further provided at the spout of the water mixing chamber in the present invention. The one-way valve maintains the closed/open state according to the presence/absence of pressure, thereby controlling switching between the open/closed state of the spout. As a result, the cleaning tank is communicated with the water supply path only when water is supplied, and the water supply path and the cleaning tank are disconnected when a program such as drying is executed. Therefore, problems such as heat loss during the drying process and contaminants such as lint entering the water supply path are avoided.

In the present invention, water other than the priming water in the first flow path flows into the washing tank through the second flow path, thereby achieving a parallel connection between the main water supply and the water suction pump, thereby increasing the water absorption speed. do. Further, the water sucked by the water suction pump flows into the washing tank through the third channel provided in the channel distribution chamber, and supplies the washing water to the washing machine. Further, after the water suction pump is started, the water supply to the first flow path may be stopped by closing the water supply valve, and water may be supplied only by the water suction pump. Since the water suction pump has a water suction function, it can suck other water accumulated in daily life into the washing machine. In particular, since the water suction pump can communicate with a large-sized water storage device such as a bathtub at home, the purpose of greatly saving the amount of water used can be achieved.

As shown in FIGS. 1 to 6, the present invention discloses a washing machine water supply device and a washing machine. A one-way communication device is provided in the water supply path of the washing machine. The one-way communication device is opened under water pressure when water is supplied to the washing machine, and remains closed after water supply is completed. In the present invention, the cleaning tank and the water supply path are communicated only when water is supplied, and the water supply path and the cleaning tank are disconnected when a program such as drying is executed. This avoids the problems of heat loss during the drying process and the ingress of contaminants such as lint into the water supply path. Also, the water supply device of the present invention receives washing water supplied from different water supply routes. In addition, by connecting the main water supply and the water suction pump in parallel using the flow path in the flow distribution chamber of the tank, there is no need for a water supply valve independently installed for the conventional water suction pump. The present invention has advantages such as a smaller number of parts, a lower cost, and a smaller occupied volume than a washing machine equipped with a water suction pump. This makes it easier for the washing machine to use another water source, such as leftover hot water from a bath, as washing water for the washing machine, thereby achieving the purpose of saving the amount of water used.

As shown in FIGS. 1 to 6, this embodiment discloses a water supply device for a washing machine. A one-way communication device is provided in the water supply path of the washing machine. The one-way communication device is opened under water pressure when water is supplied to the washing machine, and remains closed after water supply is completed.

As shown, the water supply system includes a tank 1 communicating with a water supply route. The tank 1 has a spout 61 and communicates with the washing tub of the washing machine. The one-way communication device is mounted on the spout 61 to control switching between open and closed states of the spout 61 .

In this embodiment, the one-way communication device is a one-way valve 62 mounted on the spout 61 . The material of the one-way valve shown in FIG. 6 is rubber.

As shown in FIG. 5, the washing machine of this embodiment is provided with a drying module 13 communicating with the washing tub. The drying module 13 is used for drying clothes. The one-way valve 62 is used to prevent the air in the washing tub from entering the water supply path of the washing machine when drying the clothes.

The water supply device includes a first water supply path and a second water supply path that communicate with the tank 1 and can individually supply water. The first water supply path includes a water suction pump 2 , and the second water supply path communicates with the water suction pump 2 . In this embodiment, the second water supply route supplies water to the washing tank through the water supply route of the tap.

The water suction pump 2 of the first water supply path and the second water supply path communicate with the tank 1 respectively. Tank 1 includes a tank top lid 11 . The tank 1 also includes a channel distribution chamber 5 . The channel distribution chamber 5 is provided with a first channel 51 that guides water to flow into the pump chamber of the water suction pump 2 . This realizes communication between the second water supply path and the pump chamber of the water suction pump.

The water suction pump 2 is provided with a water suction pump water inlet 21, and by the operation of the water suction pump 2, water from another water source can be sucked into the washing tank and used for washing the washing machine. In the present invention, by using the water suction pump 2 and communicating the water suction pump conduit 21 with the bathtub at home, it is possible to realize the function of washing clothes using leftover bath water. This reduces the amount of water used in the washing machine.

The washing machine of the present invention further includes a water supply path independent of the water suction pump 2 . In this embodiment, the water supply path communicates with the domestic water supply, and is controlled to open and close by the water supply valve 9 . The channel distribution chamber 5 has a first water supply end 511 and a first water discharge end 512 communicating with the first channel 51 respectively. The first water supply end 511 communicates with the water supply path of the washing machine, and the first water discharge end 512 communicates with the pump chamber of the water suction pump 2 .

In general, a suction pump must be primed to fill the pump chamber with liquid before operation. For this purpose, an independent water supply valve is required to control water flow into the pump chamber of the water suction pump, and the water suction pump can only start normal operation after the priming operation is completed. In contrast, the first flow path 51 of the present invention directly communicates with a water supply path independent of the water suction pump 2 . As a result, the main water suction and the water suction pump 2 are connected in parallel, so that the pump chamber of the water suction pump 2 is supplied with water at the same time as the water is supplied to the water supply path, that is, the priming process is also realized. As a result, since the water suction pump can be started quickly after the water supply path is opened, the conventional independent water supply valve required for priming for starting the water suction pump is omitted. Therefore, the number of parts is reduced, the cost is reduced, and the occupied volume is reduced as compared with a conventional washing machine equipped with a water suction pump.

In order to better realize the flow guiding action of the flow path, the installation height of the first water supply end 511 of the flow path distribution chamber 5 in this embodiment is set to the height of the first water discharge end 512, as shown in FIG. It is lower than the installation height. The first water supply end 511 and the first water discharge end 512 are provided on opposite sides of the channel distribution chamber 5, respectively, and the first channel crosses the channel distribution chamber. . According to such a system, it is possible not only to extend the length of the water supply circuit, but also to provide an energy buffer area for the water supply. As a result, the impact of the water flow during water supply is reduced, and the fluidity after the water flow enters the tank is reduced, so that the water flow can be caused to flow more stably in the guiding direction of the channel.

Needless to say, since the installation height of the first water supply end 511 is lower than the installation height of the first water discharge end 512, the first water supply end 511 of the first flow path 51 can be removed after using the washing machine. Puddles can form nearby, which can be a potential hygiene risk. In order to avoid the occurrence of such a situation, as shown in FIG. An opening is provided for discharging pooled water near the water supply end 511 . The opening is a pooled water drain port 513 . Since the cross-section of the pooled water outlet 513 is much smaller than the cross-section of the first water supply end 511 , a large amount of water does not leak out when the water flows in the first channel 51 . On the other hand, after the washing machine stops supplying water, it is possible to drain the accumulated water from the flow path through the accumulated water outlet 513 .

As shown in FIGS. 1 and 4, the tank further includes a mixing chamber 6 communicating with and positioned below the flow distribution chamber. Said water mixing chamber 6 communicates with the washing tub through a spout 61 allowing water from different channels in the distribution chamber to enter the washing tub 61 through said spout 61 for use in washing in the washing machine.

As shown in FIG. 3, a second channel 52 is further provided inside the channel distribution chamber 5 . Further, the channel distribution chamber 5 has a second water supply end 521 and a second water discharge end 522 communicating with the second channel 52 respectively. The second water supply end 521 communicates with the first channel 51 . The second water discharge end 522 is an opening positioned at the bottom of the flow path distribution chamber 5 and communicates with the water mixing chamber 6 . In this embodiment, the role of the second flow path 52 is to cooperate with the first flow path 51 to supply water (tap water in this embodiment) to the washing machine from the water supply path. That is, the flow direction of the water flow drawn from the water supply path by the first flow path 51 is the direction of flowing into the pump chamber of the water suction pump through the first water discharge end 512 and the direction of flow from the water mixing chamber 6 through the second flow path 52 to the washing tank. There are two directions of inflow.

As shown in FIG. 3, the second water discharge end 522 of the present embodiment is an opening located at the bottom of the flow distribution chamber 5, which directly communicates with the water mixing chamber 6 below. Similarly, the pooled water discharge port 513 in the first flow path 51 is also communicated with the water mixing chamber 6 to discharge the pooled water to the water mixing chamber 6 . The pooled water finally enters the washing tub of the washing machine through the spout 61 .

The tank of the present embodiment and the washing machine using the tank can perform the washing function by using other recovered water such as the remaining bath water sucked by the water suction pump, compared with a general washing machine. is the biggest advantage. Therefore, in the channel distribution chamber 5 of this embodiment, there is provided a third channel that guides the water in the water suction pump 2 to flow into the tank 1 and communicates with the drain port of the water suction pump 2. 53 are further provided. In addition, the channel distribution chamber 5 has a third water supply end 531 and a third water discharge end 532 communicating with the third channel 53 respectively. The third water supply end 531 communicates with the water outlet of the water suction pump, and the third water discharge end 532 of the third channel 53 communicates with the water mixing chamber 6 . As shown in FIG. 3 , the third water discharge end 532 is an opening formed at the bottom of the flow path distribution chamber 5 .

In this embodiment, the cross section of the first water discharge end 512 is smaller than the cross section of the third water supply end 531 . This is because although the amount of water for priming is not large, the amount of water at the drain port increases after the water suction pump starts operating. This saves water tube material.

The first water discharge end 512 in this embodiment is a water pipe that communicates with the pump chamber of the water suction pump 2 . An opening a7 is provided in the side wall of the flow path distribution chamber 5, and the first water discharge end 512 is connected to the opening a7. The third water supply end 531 is a water pipe that communicates with the water outlet of the water suction pump. An opening b8 is provided in the side wall of the channel distribution chamber 5, and the third water supply end 531 is connected to the opening b8. The opening a7 and the opening b8 are located on the same side wall of the flow path distribution chamber 5 on the side of the water suction pump. The role of the third flow path is to implement the process of guiding water from another water source through the suction pump to the wash basin.

As shown in FIGS. 1 to 4, this embodiment is a supplement to the first embodiment. In this embodiment, the second water supply path further includes a branch water supply path. That is, it includes the first branched water absorption passage 3 and the second branched water absorption passage 4 in the figure. The first water suction branch 3 communicates with the pump chamber of the water suction pump 2 and the washing tub of the washing machine through the tank 1 . Also, the second water absorption branch 4 communicates with the washing tub of the washing machine through the tank 1 .

A fourth flow path 54 is further provided in the flow distribution chamber 5 to guide the water flow from the second water absorption branch 4 to flow into the tank 1 . Further, the channel distribution chamber 5 has a fourth water supply end 541 and a fourth water discharge end 542 communicating with the fourth channel 54 respectively. The fourth channel 54 communicates with the additive chamber 12 . The fourth water discharge ends 542 are two round holes in the bottom of the flow distribution chamber 5, which communicate with the water mixing chamber 6 and are used to feed additives into the washing tank. As shown, the additive in this example is a softener. The softener is dosed by pouring it into the wash tub during the final rinse of the wash.

The amount of water required for dosing the softener is much less than for washing. Therefore, the first branched water absorption passage 3 and the second branched water absorption passage 4 have different water supply ports, and the water supply amount of the first water absorption branched passage 3 is larger than the water supply amount of the second water absorption branched passage 4. It's becoming That is, the cross section of the water supply port of the first branched water absorption passage 3 is larger than the cross section of the water supply port of the second water absorption branched passage 4, and the cross section of the fourth water supply end 541 is larger than the cross section of the first water supply end 511. small.

Furthermore, the water supply system includes a water supply valve 9 . The water supply valve 9 communicates with the water supply ports of the first branched water absorption passage 3 and the second branched water absorption passage 4, and is used to control water supply from the first branched water absorption passage 3 and the second branched water absorption passage 4. be done.
