The following describes the diverter tray of the water dispenser according to the first aspect of the present invention with reference to the accompanying drawings, and it should be noted that the diverter tray of the present invention can be applied to the cold tank of the water dispenser and other components that need to be diverted, taking the application of the diverter tray to the cold tank as an example: as shown in figure 3, the volume of the cold tank in the water dispenser can be divided into a cold water area 12 wrapped by the evaporator and a warm water area 11 not wrapped by the evaporator, and the diverter disc in the cold tank can prevent the natural convection and heat conduction heat exchange of the warm water and the cold water in the cold tank.

As shown in fig. 2 to 8, the diverter tray of the water dispenser according to the embodiment of the present invention includes at least two transverse partition plates, and the transverse partition plates are suitable for being arranged at intervals along the length direction of the tank body 1.

Among the above-mentioned plurality of diaphragms, the diaphragm located at the top is a top diaphragm 21, and the diaphragm located at the bottom is a bottom diaphragm 22, wherein an accommodating space 20 suitable for accommodating liquid is formed between the top diaphragm 21 and the bottom diaphragm 22, and the top diaphragm 21 is provided with an inlet groove 211, the bottom diaphragm 22 is provided with an outlet groove 221, and the inlet groove 211, the accommodating space 20 and the outlet groove 221 are communicated with each other.

According to the embodiment of the utility model, the cold tank of the water dispenser is taken as an example for explanation, and the flow distribution plate is applied to the cold tank of the water dispenser: the jar of body 1 of cold tank forms the water storage chamber, and the flow distribution dish is fixed in the water storage chamber, and at this moment, a plurality of cross slab crossbands are in the water storage chamber to a plurality of cross slab set up along the length direction interval in water storage chamber, thereby the cross slab separates the water storage chamber for three region, and three region is respectively for the warm water district 11 that is located top cross slab 21 top, the accommodation space 20 between top cross slab 21 and the top cross slab 21, and be located the cold water district 12 of bottom cross slab 22 below.

It can be understood that in the water dispenser, the hot tank supplies water to the warm water area 11 through the pipeline, and the warm water area 11 supplies water to the cold water area 12 through the diversion plate, therefore, in the utility model, when the water amount in the cold water area 12 is insufficient, the water in the warm water area 11 enters the accommodating space 20 through the inlet groove 211 on the top transverse partition plate 21, and the water in the accommodating space 20 enters the cold water area 12 through the outlet groove 221 on the bottom transverse partition plate 22, so that the water supply of the warm water area 11 to the cold water area 12 is realized.

As shown in fig. 1, in the related art, the diverter disc of the conventional water dispenser cold tank has only one layer of flat diverter disc 001, warm water is above the flat plate, and cold water is below the flat plate, and the effect of preventing temperature cross between the warm water and the cold water is not realized effectively, so that the warm water consumes cold energy, a phenomenon of no warm water occurs, and meanwhile, the refrigeration and heat preservation time is short, and the refrigeration energy consumption is high.

In order to solve the technical problems in the related art, the splitter plate provided by the utility model is provided with at least two layers of diaphragm plates, so that the heat insulation effect and the temperature cross-over prevention effect between the hot water area 11 and the cold water area 12 in the cold tank are better.

Furthermore, since the accommodating space 20 is formed between the top transverse partition 21 and the bottom transverse partition 22, water in the warm water region 11 firstly enters the accommodating space 20 and then enters the cold water region 12, at this time, the temperature of water in the warm water region 11 is higher than that in the accommodating space 20, and the temperature of water in the accommodating space 20 is higher than that in the cold water region 12.

It can be understood that, in the present invention, since the warm water region 11 is adjacent to the accommodating space 20 but not adjacent to the cold water region 12, the water in the warm water region 11 directly exchanges heat with the water in the accommodating space 20, and since the temperature difference between the warm water region 11 and the accommodating space 20 is much smaller than the temperature difference between the warm water region 11 and the cold water region 12, compared with the related art in which the warm water region 11 directly exchanges heat with the cold water region 12, in the present invention, the heat exchange efficiency between the accommodating space 20 and the warm water region 11 is worse, so that the adverse effect (i.e. temperature reduction) on the warm water region 11 is smaller, and the water temperature of the warm water region 11 can be maintained at a higher temperature value to meet the use requirement of the user.

Similarly, in the present invention, since the cold water region 12 is adjacent to the accommodating space 20 but not adjacent to the warm water region 11, the water in the cold water region 12 directly exchanges heat with the water in the accommodating space 20, and since the temperature difference between the cold water region 12 and the accommodating space 20 is much smaller than the temperature difference between the warm water region 11 and the cold water region 12, compared with the related art, in the present invention, the heat exchange efficiency between the accommodating space 20 and the cold water region 12 is worse, so that the adverse effect (i.e., temperature rise) on the cold water region 12 is smaller, and the water temperature of the cold water region 12 can be maintained at a lower temperature value to meet the use requirement of the user.

In conclusion, the accommodating space 20 formed by the diverter tray of the present invention can play a role of transition and buffering, so as to avoid the direct adjacency of the cold water region 12 and the warm water region 11, and further reduce adverse effects brought by the warm water region 11 on the cold water region 12, that is, reduce the consumption of cold energy by the warm water, and reduce adverse effects brought by the cold water region 12 on the warm water region 11, that is, reduce the consumption of heat by the cold water, so that not only the water temperature of the warm water region 11 can be raised, but also the water temperature of the cold water region 12 can be ensured to be at a lower value, the refrigeration energy consumption is reduced, and the refrigeration and heat preservation time is prolonged.

In conclusion, the flow distribution disc of the water dispenser has better heat insulation and temperature cross prevention effects, can ensure that the water temperature of the warm water area 11 and the water temperature of the cold water area 12 respectively meet the use requirements, reduces the refrigeration energy consumption, and prolongs the refrigeration and heat preservation time.

It should be noted that, the number of the diaphragm plates in the present invention is not particularly limited, as long as the diaphragm plates in the diversion plate have at least two layers and can form the accommodating space 20.

As shown in fig. 3 to 6, in an embodiment of the present invention, taking the number of the diaphragm plates as two for illustration, the diverter tray includes a support 23 and a diaphragm assembly fixed on the outer circumferential surface of the support 23, the diaphragm assembly includes only two diaphragm plates, and the two diaphragm plates are a top diaphragm plate 21 and a bottom diaphragm plate 22, respectively, and the top diaphragm plate 21 and the bottom diaphragm plate 22 are spaced apart along the length direction of the support 23.

An accommodating space 20 is formed between the top diaphragm plate 21 and the bottom diaphragm plate 22, an inlet groove 211 is formed on the top diaphragm plate 21, an outlet groove 221 is formed on the bottom diaphragm plate 22, and the inlet groove 211, the accommodating space 20 and the outlet groove 221 are sequentially communicated.

Compared with the embodiment that three transverse partition plates and four transverse partition plates with equal quantity are arranged, only two transverse partition plates are arranged in the embodiment, so that the flow path of water flowing from the inlet groove 211 to the outlet groove 221 is short, the water quantity flowing into the cold water area 12 in the embodiment is larger, the cold water discharging quantity is larger, and the heat insulation effect of the double-layer structure in the embodiment is not different from that of the multi-layer structure, so that the size of the heat insulation effect and the cold water discharging quantity can meet the use requirement by the double-layer transverse partition plate structure in the embodiment, and a better balance relation is kept between the heat insulation effect and the cold water discharging quantity.

In addition, in this embodiment, top diaphragm 21 and bottom diaphragm 22 are fixed in support piece 23 respectively to diverter plate's overall stability is higher, and diverter plate's independence is also better, makes things convenient for diverter plate's installation, dismantlement and change.

As shown in fig. 4, according to an embodiment of the present invention, the supporting member 23 has a first end and a second end opposite to each other along the length direction thereof, wherein the top diaphragm 21 and the bottom diaphragm 22 are both disposed at the first end of the supporting member 23, and the second end of the supporting member 23 is adapted to be connected to the tank body 1 of the cold tank, so as to realize the installation and fixation of the diverter tray inside the tank body 1.

It should be noted that the supporting member 23 may be a supporting column, a supporting plate, or a supporting rod, and the diaphragm may be a circular diaphragm, a square diaphragm, or a polygonal diaphragm, and the specific shape of the supporting member 23 and the specific shape of the diaphragm are not specifically limited in the present invention.

As shown in fig. 3-6, in one embodiment of the utility model, the support 23 may be a support post, and both the top diaphragm 21 and the bottom diaphragm 22 may be circular diaphragms. When the flow distribution disc was installed in columniform jar body 1, the length direction of support column was the same with the length direction of jar body 1, and top cross slab 21 and bottom cross slab 22 are all fixed in the upper end of support column, and the lower extreme of support column is fixed on the diapire of jar body 1. The top diaphragm plate 21 and the bottom diaphragm plate 22 are respectively adapted to the tank body 1, so that a warm water region 11 is formed between the top diaphragm plate 21 and the top wall of the tank body 1, and a cold water region 12 is formed between the bottom diaphragm plate 22 and the bottom wall of the tank body 1, and the warm water region 11 and the cold water region 12 are communicated through a flow guide channel formed by the inlet groove 211, the accommodating space 20 and the outlet groove 221.

As shown in fig. 6, a first guide plate 24 is connected between the top diaphragm 21 and the bottom diaphragm 22, and the first guide plate 24 is adapted to guide the flow of water entering the inlet slot 211 into the accommodating space 20. Like this, first guide plate 24 can play the water conservancy diversion effect to in leading the rivers in the warm water district 11 to accommodation space 20 more smoothly, the water conservancy diversion effect is better.

As shown in fig. 6, in one embodiment of the present invention, the top diaphragm 21 and the bottom diaphragm 22 are spaced apart in the up-down direction, the upper end of the first baffle 24 is fixed to the edge of the inlet tank 211, the lower end of the first baffle 24 is fixed to the upper surface of the bottom diaphragm 22, and the first baffle 24 extends obliquely from the edge of the inlet tank 211 to the bottom diaphragm 22.

As shown in fig. 6, according to one embodiment of the present invention, a second flow guide plate 25 is provided at the outlet groove 221, and the second flow guide plate 25 is adapted to guide the water flow in the accommodating space 20 to the outside of the outlet groove 221. In this way, the second flow guiding plate 25 can guide the water flow in the accommodating space 20 to the outside of the outlet groove 221 (i.e., in the cold water region 12) more smoothly.

As shown in fig. 6, in one embodiment of the present invention, the second baffle 25 extends obliquely away from the top diaphragm 21, that is, the second baffle 25 extends obliquely downward, wherein the upper end of the second baffle 25 is fixed to the edge of the outlet trough 221, and the lower end of the second baffle 25 extends obliquely inward of the cold water region 12.

As shown in fig. 1, in a water dispenser in the related art, a single-layer diverter disc 001 is generally disposed in a cold tank, and an overflow gap 002 is left between the single-layer diverter disc 001 and an inner wall surface of a tank body, so that water in a warm water area flows into a cold water area.

That is, the circulation of water flow between the warm water district and the cold water district of correlation technique is realized through the clearance 002 that overflows between single-deck flow divider 001 and the internal face of jar, and above-mentioned mode of draining has following defect: firstly, the overflowing gap 002 needs to play a water supply function, so the size of the overflowing gap 002 is usually set to be larger, and the problem of temperature crosstalk between a warm water area and a cold water area is more serious; the second, through establishing the clearance 002 that overflows that divides the flow distribution plate 001 border position and realize the function of draining, the water conservancy diversion effect is relatively poor usually, makes the internal stagnant water district that appears of jar easily to cause harmful effects to the volume of discharging cold water, for example, be close to the regional rivers of flow distribution plate 001 center because far away from dividing the flow distribution plate 001 border, consequently can't be derived to cold water district smoothly usually, thereby cause the reduction of the volume of discharging cold water.

As shown in fig. 3 to 6, in order to solve the above-mentioned disadvantages of the related art, according to an embodiment of the present invention, the top diaphragm 21, the first baffle 24, the bottom diaphragm 22 and the second baffle 25 together define a guide passage (not shown).

Therefore, in the embodiment, the gap between the diaphragm plate and the inner wall of the tank body 1 is not required to be used for water drainage, but the water drainage from the warm water area 11 to the cold water area 12 is realized through the flow guide channel, on one hand, due to the transition and buffering effects of the accommodating space 20, the water drainage mode can effectively prevent the temperature cross-connection problem between the warm water area 11 and the cold water area 12, so that the refrigeration energy consumption is reduced, and the refrigeration and heat preservation duration is prolonged; on the other hand, the inlet tank 211 and the outlet tank 221 can reduce the existence of the dead water zone in the tank body 1 as much as possible, and the first guide plate 24 and the second guide plate 25 can improve the flow guiding effect in the water discharging process, so that the water flow in the warm water zone 11 can be smoothly discharged into the cold water zone 12, and in sum, the water discharging mode can also realize the improvement of the cold water discharging amount.

It should be noted that in one embodiment of the present invention, when the diverter tray is installed in the tank 1 of the cold tank, the edges of the diaphragms (i.e. the top diaphragm 21 and the bottom diaphragm 22, etc.) may be spaced from the inner wall of the tank 1. It will be understood that the reason for the above-mentioned "spacing" is not to realize the water discharging function, but to leave the installation gap 13 for the installation of the diverter tray, thereby facilitating the installation of the diverter tray. In this embodiment, the value of the mounting gap 13 is usually much smaller than that of the overcurrent gap in the related art, for example, the value of the mounting gap 13 may be in a range of 1mm to 5 mm.

According to an embodiment of the present invention, the flow guide passage is spirally wound on the support 23 along the length direction of the support 23. Therefore, the flow guide channel is designed into a spiral structure, so that the flow guide efficiency can be further improved, and the cold water discharge amount is further improved.

As shown in FIG. 6, according to one embodiment of the utility model, the top diaphragm 21 and the bottom diaphragm 22 may both be horizontal and perpendicular to the support 23.

According to another embodiment of the utility model, at least one of the top diaphragm 21 and the bottom diaphragm 22 extends spirally downward around the support 23. For example, the top diaphragm 21 extends obliquely downward, an inlet slot 211 is formed between the top end and the bottom end of the top diaphragm 21, and the bottom end of the top diaphragm 21 is connected to the top end of the first guide plate 24, so that the water flow in the warm water region 11 is guided into the inlet slot 211 through the top diaphragm 21 and guided into the accommodating space 20 through the first guide plate 24. For another example, the bottom diaphragm 22 extends spirally and downwardly, an outlet groove 221 is formed between the upper end and the lower end of the bottom diaphragm 22, and the lower end of the bottom diaphragm 22 is connected to the upper end of the second flow guide plate 25, so that the water flow in the accommodating space 20 is guided into the outlet groove 221 through the bottom diaphragm 22 and guided into the cold water area 12 through the second flow guide plate 25.

As shown in fig. 8, according to a further embodiment of the present invention, at least a portion of the bottom diaphragm 22 extends obliquely away from the top diaphragm 21 to form a flow guide surface adapted to guide liquid entering the receiving space 20 to the outlet slot 221. Like this, on the one hand, compare in spiral decurrent structure, bottom diaphragm 22's manufacturing is simpler, and on the other hand can further improve bottom diaphragm 22's water conservancy diversion effect through setting up the water conservancy diversion face to improve the cold water yield.

As shown in fig. 8, in one embodiment of the utility model, the bottom diaphragm 22 includes a first cross partition 222 and a second cross partition 223 having a height difference, the first cross partition 222 being disposed adjacent to the top diaphragm 21 and connected to the first baffle 24, and the second cross partition 223 being disposed away from the top diaphragm 21 and connected to the second baffle 25.

The bottom diaphragm 22 further comprises a flow guiding region 224 for connecting the first 222 and the second 223 cross partition, which flow guiding region 224 forms a flow guiding surface.

As shown in fig. 8, in one embodiment of the present invention, the bottom diaphragm 22 is a circular diaphragm, the first transverse partition 222 and the second transverse partition 223 are complementary semicircular plates, respectively, the first transverse partition 222 is located above the second transverse partition 223, and the diversion area 224 connects the first transverse partition 222 and the second transverse partition 223 and is inclined downward. The center of the bottom diaphragm 22 coincides with the center of the support member 23, and the outlet groove 221 and the guide area 224 are formed at opposite sides of the support member 23, respectively.

As shown in fig. 7, according to one embodiment of the present invention, the inlet slots 211 extend from the support 23 to the outer edge of the top diaphragm 21, such that the width of the inlet slots 211 is greater to further avoid the occurrence of dead water above the top diaphragm 21.

As shown in fig. 8, according to an embodiment of the present invention, the outlet groove 221 extends from the supporting member 23 to the outer edge of the bottom diaphragm 22, so that the width of the outlet groove 221 is greater, thereby further preventing the occurrence of a dead water zone in the accommodating space 20.

As shown in fig. 6, according to an embodiment of the present invention, at least one connecting column 26 is disposed between the top diaphragm 21 and the bottom diaphragm 22, and an overflowing hole 261 is opened on the connecting column 26.

To increase the structural strength of the diverter tray, a connecting post 26 may be provided between the top diaphragm 21 and the bottom diaphragm 22. The connecting post 26 may be integrally formed with the top diaphragm 21 or the bottom diaphragm 22, or may be removably connected to the top diaphragm 21 or the bottom diaphragm 22.

In order to avoid the resistance caused by the connecting column 26 to the water flow, the overflowing hole 261 is further formed in the connecting column 26, so that when the water flow passes through the connecting column 26, the water flow can flow out through the overflowing hole 261, and the flowing resistance of the connecting column 26 to the water flow is reduced through the arrangement of the overflowing hole 261. The overflowing hole 261 may be one or more, and when the overflowing hole 261 is plural, the plural overflowing holes 261 may be spaced apart from each other along the height direction of the connecting column 26.

The reinforcing ribs 27 may be provided on the upper surface of the bulkhead or may be provided on the lower surface of the bulkhead. Meanwhile, the extending direction of the reinforcing beads 27 is not particularly limited, and for example, the reinforcing beads 27 may extend in the radial direction of the diaphragm.

A cold tank of a water dispenser according to an embodiment of the second aspect of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 2 to 8, the cold tank comprises a diverter tray according to the first aspect of the present invention, and further comprises a tank body 1 and a refrigeration unit 3. Wherein, jar body 1 is formed with the water storage chamber, and the flow distribution dish is established in jar body 1 in order to divide into warm water district 11 and cold water district 12 with the water storage chamber. The side wall of the tank 1 corresponding to the cold water region 12 is provided with a refrigeration part 3.

As shown in fig. 1, in the related art, the diversion plate of the water dispenser is usually a single-layer diversion plate 001, and the evaporator 003 is usually as high as the diversion plate 001 or slightly higher than the diversion plate 001, so that the evaporator 003 is directly adjacent to the warm water zone, and the cold energy generated by the evaporator 003 is easily consumed by the warm water zone, thereby on one hand, wasting the cold energy, prolonging the refrigeration startup time, increasing the refrigeration energy consumption, and shortening the refrigeration and heat preservation time; on the other hand, heat loss in the warm water area is caused, so that the water temperature in the warm water area is reduced, and the use requirement of a user cannot be met.

As shown in fig. 2 and 3, in order to solve the above technical problem, according to an embodiment of the present invention, the diversion tray includes a top diaphragm 21 and a bottom diaphragm 22, and a receiving space 20 is formed between the top diaphragm 21 and the bottom diaphragm 22.

In this way, on the one hand, the area directly adjacent to the refrigerating component 3 remains the accommodation space 20 instead of the warm water area 11, thus reducing the consumption of cold; on the other hand, at least one part of the accommodating space 20 is arranged opposite to the refrigeration part 3, so that the refrigeration part 3 can also perform a refrigeration function on part of water flow in the accommodating space 20, thereby precooling the water flow before entering the cold water area 12 in advance and facilitating the rapid refrigeration of the water in the cold water area 12.

In conclusion, when the diameter of the transverse partition plate is greatly different from the diameter of the inner wall of the tank body 1, the heat insulation effect is poor, so that the effect of reducing the refrigeration energy consumption is not obvious.

In addition, in order to study the influence of the installation gap 13 on the cold water discharge quantity of the water dispenser, the utility model respectively tests the cold water discharge quantity of the water dispenser when the difference between the diameter of the transverse partition plate and the diameter of the inner wall of the tank body 1 is 25mm and 3mm (namely, the distance between the edge of the transverse partition plate and the inner wall of the cold tank is 12.5mm and 1.5mm respectively), and obtains the following results: when the distance between the edge of the transverse partition plate and the inner wall of the cooling tank is 12.5mm, the amount of cold water discharged is between 4900ml and 5000 ml; when the distance between the edge of the transverse partition plate and the inner wall of the cooling tank is 1.5mm, the amount of the cold water is 5300ml to 5400 ml.
