Description

Technical Field

[0001] The invention belongs to the field of household appliances, and in particular relates to a dishwasher. Background Art

[0002] Existing dishwashers are generally equipped with a water softening device. This device needs to be periodically added with special salt when in use to replace the Ca, Mg and other ions in the water softening device so that the water softening device can continuously maintain the ability to soften water. The salt adding port of the water softening device is designed at the bottom of the washing chamber. During the adding process, the user needs to take out the tableware and the bowl rack before adding salt to the water softening device, which is troublesome. At the same time, during the adding process, since the softener is full of water, after adding salt, the salt will overflow from the salt adding port, and long-term use will cause the sheet metal at the bottom of the washing chamber to rust.

[0003] The Chinese patent application number CN201520251760 discloses a high water level alarm device for a dishwasher and a dishwasher, which solves the technical problem of high complexity of the design of the high water level alarm structure in the existing dishwasher. The dishwasher includes a water softener and a washing chamber, and an alarm device on the inner side of the bottom of the outer shell of the dishwasher; the water softener is a thin integrated cavity, which is vertically placed between the washing chamber and the inner side of the outer shell of the dishwasher; and the water outlet of the water softener is connected to the water inlet of the washing chamber through a connector, so that the water softener and the washing chamber are connected; an overflow port is provided on the upper side of the water outlet of the water softener. When the water level in the washing chamber rises to the warning water level, the water level in the water softener cavity rises to the overflow port together, and the overflow water flows from the overflow port of the water softener cavity to the bottom of the dishwasher, triggering the alarm device to alarm. The salt adding port of the water softening device of the dishwasher in this application is located in the dishwasher. During the adding process, the user needs to take out the tableware and the bowl rack before adding salt to the water softening device, which is troublesome to operate. At the same time, during the adding process, since the softener is full of water, after adding salt, the salt will overflow from the salt adding port. Long-term use will cause rust on the sheet metal at the bottom of the washing chamber.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dishwasher. The salt adding port of a water softening device is located outside the housing, so that a user can directly see the salt adding port and add salt by opening the salt adding port. The operation is simple and convenient. A backflow channel is also provided inside the water softening device. Once the water level in the softener is about to reach the salt adding port, the water can flow out through the backflow channel, thereby avoiding the problem of brine flowing out directly from the salt adding port after adding salt.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a dishwasher, including a shell, a washing water tank is arranged in the shell, and a water softener is also arranged in the dishwasher, the water softener includes a water softening chamber and a regeneration chamber, the water softening chamber is provided with an ion exchange resin, the regeneration chamber is provided with an ion regeneration material, and the shell is provided with an inlet connected to the regeneration chamber for introducing the ion regeneration material.

[0007] The shell is provided with a groove opening, and the operation interface with an inlet of the water softener is located at the groove opening. The user can directly see the salt adding port, and salt can be added by opening the salt adding port, which is simple and convenient to operate.

[0008] The operation interface is an inclined surface with an inclination angle of 75° to 30°. If the operation interface is a flat surface, the user needs to put his hand into the groove, which is inconvenient to operate. If the operation interface is a vertical surface, because the channel for the salt to flow downward is a vertical surface, there must be a vertical turning point between the operation interface and the channel, and the added salt is not easy to flow downward.

[0009] The water softener is also provided with an overflow channel to prevent liquid from flowing out of the inlet. The top of the overflow channel is lower than the inlet. Once the water level in the softener is about to reach the salt adding port, it can flow out through the backflow channel, avoiding the problem of brine flowing out directly from the salt adding port after adding salt.

[0010] The regeneration chamber is a salt water pool for holding salt water, the ion regeneration material is salt, the overflow channel is located above the salt water pool and communicates with the salt water pool, the inlet is connected to the salt water pool through the salt water cavity, the overflow channel communicates with the salt water cavity through the salt water pool, and the water level height can be kept the same at all times. After adding salt, the water level in the salt water cavity rises, which can be avoided through the overflow channel.

[0011] The overflow channel is communicated with the water outlet of the water softener, and the overflowed water flows out through the water outlet, thereby preventing the water from overflowing from the salt adding port.

[0012] A one-way switch mechanism is provided at the top of the overflow channel, which allows water to flow from the overflow channel to the water outlet. When the water level in the salt chamber is higher than the top of the overflow channel, the switch mechanism opens and water flows out of the overflow channel. When the water level is lower than the top of the overflow channel, the switch mechanism closes, so that water can only flow from the overflow channel to the water outlet, while preventing reverse flow.

[0013] The one-way switch mechanism comprises a floating ball, a one-way sealing structure located in the overflow channel, and a limiting structure away from the overflow channel.

[0014] The vertical part of the water softener with the inlet is located between the housing and the washing water tank, and the horizontal part of the water softener is located below the washing water tank.

[0015] The inlet is provided with a detachable sealing cover to prevent impurities from entering the brine chamber, thereby ensuring the cleanliness of the water softener and facilitating the salt adding operation.

[0016] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0017] 1. The housing is provided with a groove, and the operation interface with an entrance of the water softener is located at the groove. The user can directly see the salt adding port, and can add salt by opening the salt adding port, which is simple and convenient to operate;

[0018] 2. The operation interface is an inclined surface with an inclination angle of 75° to 30°. If the operation interface is a flat surface, the user needs to put his hand into the groove, which is inconvenient to operate. If the operation interface is a vertical surface, because the channel for the salt to flow downward is a vertical surface, there must be a vertical turning point between the operation interface and the channel, and the added salt is not easy to flow downward;

[0019] 3. The water softener is also provided with an overflow channel to prevent the liquid from flowing out from the inlet. The top of the overflow channel is lower than the inlet. Once the water level in the softener is about to reach the salt adding port, it can flow out through the backflow channel, thus avoiding the problem of salt water flowing out directly from the salt adding port after adding salt;

[0020] 4. The overflow channel is connected to the brine chamber through the brine pool, which can keep the water level the same at all times. After adding salt, the water level in the brine chamber rises, which can be avoided through the overflow channel;

[0021] 5. The overflow channel is connected to the water outlet of the water softener, and the overflowed water flows out through the water outlet, thereby preventing water from overflowing from the salt adding port;

[0022] 6. A one-way switch mechanism is provided at the top of the overflow channel to allow water to flow from the overflow channel to the water outlet. When the water level in the salt chamber is higher than the top of the overflow channel, the switch mechanism is opened and water flows out of the overflow channel. When the water level is lower than the top of the overflow channel, the switch mechanism is closed, so that water can only flow from the overflow channel to the water outlet, and reverse flow is prevented;

[0023] 7. A detachable sealing cover is provided on the inlet to prevent impurities from entering the brine chamber, thereby ensuring the cleanliness of the water softener and facilitating the salt adding operation.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] like Figures 1 to 4 As shown, a dishwasher of the present invention comprises a shell 1, a washing water tank 2 is arranged in the shell 1, a water softener 3 is also arranged in the dishwasher, the water softener comprises a water softening chamber and a regeneration chamber, an ion exchange resin is arranged in the water softening chamber, an ion regeneration material is arranged in the regeneration chamber, and an inlet 4 is arranged on the shell 1, which is communicated with the regeneration chamber and is used to put the ion regeneration material.

[0036] The housing 1 is provided with a groove opening 6 , and an operation interface 7 with an inlet 4 of the water softener 3 is located at the groove opening 6 .

[0037] The water softener 3 is also provided with an overflow channel 5 to prevent liquid from flowing out of the inlet 4 , and the top of the overflow channel 5 is lower than the inlet 4 .

[0038] Embodiment 1

[0039] like Figure 1 As shown, the groove opening 6 on the dishwasher housing 1 described in this embodiment is located in the middle and upper part of the housing directly in front of the dishwasher. The width of the groove opening 6 is about half of the width of the housing 1, and the height is between 5-50 cm. The vertical part of the water softener 3 is located between the housing 1 and the washing sink 2. The operation interface 7 is located at the top of the vertical part, with the same height as the groove opening 6 and the same size as the groove opening 6. The operation interface 7 is an inclined surface with an inclination angle of 75°-30°. The operation interface 7 can be operated accordingly from the groove opening 6.

[0040] Embodiment 2

[0041] like Figure 3 , Figure 4As shown, the water softener 3 described in this embodiment is L-shaped, and is divided into a vertical part and a horizontal part. The vertical part with an inlet 4 is located between the housing 1 and the washing water tank 2. The horizontal part of the water softener 3 includes a water softening chamber and a regeneration chamber, which are located below the washing water tank 2. The water softening chamber is provided with an ion exchange resin, and the regeneration chamber is provided with an ion regeneration material, both of which are sealed with an upper cover. The regeneration chamber is a salt water pool 8 for containing salt water, and the ion regeneration material is salt. The salt water pool 8 is connected to the vertical part of the water softener 3, and the overflow channel 5 is located above the salt water pool 8 and communicates with the salt water pool 8. The inlet 4 and the salt water pool 8 are connected through the salt water chamber 9, and the overflow channel 5 is connected with the salt water chamber 9 through the salt water pool 8, forming a U-shaped structure, keeping the water level of the overflow channel 5 and the salt water chamber 9 at the same height, and the height of the overflow channel 5 is less than the salt water chamber 9. After adding salt, the water level of the salt water chamber 9 rises, so that the water level of the overflow channel 5 also rises at the same time. The overflow channel 5 is connected with the water outlet of the water softener 3. When the height exceeds the overflow channel 5, water will flow from the overflow channel 5 to the water outlet of the water softener 3. The height of the overflow channel 5 is less than the salt water chamber 9, thereby preventing water from overflowing from the inlet 4 when the user adds salt. The inlet 4 is provided with a detachable sealing cover, which can be a threaded seal. When adding salt, unscrew the sealing cover of the inlet 4, add salt, and then seal the inlet 4 with the sealing cover.

[0042] Embodiment 3

[0043] This embodiment is a further limitation of the above-mentioned embodiment 2. A one-way switch mechanism is provided at the top of the overflow channel 5. The one-way switch mechanism only allows water to flow from the overflow channel 5 in the direction of the water outlet of the water softener 3, while preventing water from flowing from the water outlet of the water softener 3 to the overflow channel 5. When the water level of the brine chamber 9 is higher than the top of the overflow channel, the one-way switch structure opens and water flows out of the overflow channel. When the water level is lower than the top of the overflow channel, the switch mechanism closes.

[0044] The one-way switch mechanism includes three parts: a float 10, a one-way sealing structure located in the overflow channel 5, and a limiting structure away from the overflow channel 5. The one-way sealing structure is located below the float, and the limiting structure limits the float from flowing upward or in the direction of the water flow. The float is a hollow rubber ball. The one-way sealing structure is located below the float 10. The one-way sealing structure is in the shape of a spherical crown, which matches the shape of the float 10. A hole is provided at the bottom of the one-way sealing structure. When salt is added, the water level in the salt water chamber 9 rises, causing the water level in the overflow channel 5 to rise. , water contacts the float through the hole at the bottom of the one-way sealing structure, the float floats up, the one-way switch structure opens, and water flows from the overflow channel 5 to the water outlet of the water softener 3. Due to the limited structure next to the float, the float has limited activity space and will not flow away with the water flow; when the water level is lower than the one-way sealing structure, no water enters the hole at the bottom of the one-way sealing structure, the float will not float up and will naturally fall on the one-way sealing structure. Due to the matching appearance, there is no gap between the float and the one-way sealing structure, thereby preventing the reverse flow of water.

[0045] Embodiment 4

[0046] This embodiment is a further limitation of the above-mentioned embodiment three. The limiting mechanism is located above the float and is connected to the float through a spring. When the water level is lower than the one-way sealing structure, the spring presses the float so that there is no gap between the float and the one-way sealing structure, and the one-way switch structure is closed to prevent the reverse flow of water. When the water level is higher than the one-way sealing structure, it rises through the hole below the one-way sealing structure, the buoyancy of the float is greater than the elastic force of the spring, the float rises, and the one-way switch structure opens.

[0047] Embodiment 5

[0048] A sink-type dishwasher described in this embodiment uses a side cavity of a stainless steel sink as a washing cavity of the dishwasher, a sealing cover that can be opened and closed is provided on the top, a spray device is provided inside, a shell 1 is provided on the outside of the sink, a groove 6 is provided in the shell 1, and the groove 6 cooperates with the water softener operation surface. The salt adding port and the brightener adding port of the water softener 3 are located at the upper part of the operation surface and can be directly touched by the user. The operation surface is an inclined surface with an inclination angle of 75° to 30°; an overflow channel 5 is provided in the water softener 3, and the channel is connected to the water softener outlet. A float 10 is provided at the top of the overflow channel 5. When the water level in the water softener 3 rises due to the addition of salt, the float 10 will float up, and the water flow above the channel will flow out through the overflow port, so that the water level in the salt cavity is not higher than the top of the overflow channel 5, and the top of the overflow channel 5 is lower than the salt adding port. Therefore, during the salt adding process, no water will overflow from the salt adding port.

[0049] Alternatively, an overflow channel 5 is provided in the water softener 3, and this channel is connected to the water softener outlet. A one-way valve is provided at the top of the overflow channel 5. When the water level in the brine chamber 9 is higher than the top of the overflow channel 5, the one-way valve opens and water flows out from the overflow channel 5. When the water level is lower than the top of the overflow channel 5, the one-way valve closes, and the top of the overflow channel 5 is lower than the lowest point of the salt adding port.

[0050] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
