Further, the entire contents of the configurations shown in the following embodiments are not limited to those necessary as a solution of the invention described in the claims.

Referring to fig. 1, an embodiment of the present invention provides a detergent adding device, including a horizontal pipe 1, a detergent holding tank 2 and a detergent replenishing tank 3. Wherein, the horizontal pipe 1 is horizontally arranged, optionally, the horizontal pipe 1 is a round pipe. The first end of the horizontal pipe 1 is used for connecting with the washing water, for example, the washing water is communicated with the washing water through a water pump, so that the washing water is pumped into the horizontal pipe under the action of the water pump. The second end of the horizontal pipe 1 is used for communicating with the washing device 12 to guide the washing water in the horizontal pipe 1 into the washing device 12. The horizontal pipe 1 is provided with a throat section 4 between the first end and the second end, and the cross section area of the throat section 4, which is vertical to the axial direction of the horizontal pipe 1, is smaller than the cross section area of the horizontal pipe 1, which is vertical to the axial direction of the horizontal pipe 1. Referring to FIG. 1, the throat section 4 is connected at each end to a first end and a second end of the horizontal tube 1 by a tapered portion. The detergent containing tank 2 and the detergent replenishing tank 3 are used for containing detergent. The detergent holds pond 2 and sets up in horizontal pipe 1 below, and the detergent holds pond 2 and passes through connecting pipe 5 and throat section 4 intercommunication. Alternatively, the connecting tube 5 is a circular tube. The detergent replenishment tank 3 is provided with a communication hole for communicating with the detergent storage tank 2, and further includes a switching means for opening and closing the communication hole. When the detergent liquid level in the detergent containing pool 2 descends, the switch device is turned on, so that the detergent supplementing pool 3 is communicated with the detergent containing pool 2, the detergent in the detergent supplementing pool 3 is guided into the detergent containing pool 2, the detergent liquid level in the detergent containing pool 2 is kept constant, and the detergent dosage entering the horizontal pipe 1 from the connecting pipe 5 is prevented from being influenced by the liquid level change of the detergent containing pool 2.

Taking the detergent adding device shown in FIG. 1 as an example, assume that the velocity, pressure, relative height and cross-sectional area of washing water at the I-I cross-section of the first end of the horizontal pipe 1 are respectively represented by v₁、p₁、z₁And A₁Represents; velocity, pressure, relative height and cross-sectional area of washing water at throat section II-II v₂、p₂、z₂And A₂Represents; the flow area of the connection pipe 5 is A'₂The flow speed of the detergent in the connecting pipe 5 is v'₂(ii) a Velocity, pressure, relative height and cross-sectional area of flow at the cross-section of the detergent-holding tank III-III₃、p₃、z₃And A₃And (4) showing.

Analyzing the total flow Bernoulli equation of the I-I section and the II-II section at the main flow:

wherein alpha is₁And alpha₂The kinetic energy correction coefficients of the two sections are respectively shown, the flow speed of the washing water in the conveying process is larger than 1 meter per second, the pipe diameter is not smaller than 1 centimeter, the horizontal pipe 1 is internally provided with fully developed turbulence, and the kinetic energy correction coefficients are all 1. And because the relative heights of the centers of the two sections are consistent, z can be taken₁＝z₂0.Δ h represents the loss of on-way resistance and local resistance consumed by the flow between the two sections.

And the fluid flow satisfies the continuity, namely: v. of₁A₁＝v₂A₂

Thus based on the above two equations, there are:

it can be seen that the pressure at the throat section drops due to the increase in flow velocity and the presence of flow losses. Similarly, the flow of the detergent between the II-II and III-III sections is used as a research object, and the corresponding total flow Bernoulli equation and continuity equation can be obtained:

and

v₃A₃＝v′₂A′₂

because the liquid level area A of the detergent containing pool₃Is far larger than the flow area A 'of the connecting pipe 5'₂Then v is₃Indicating the speed at which the level of the detergent-holding tank drops, negligible, i.e. v₃0.Δ h' represents the flow loss (including the on-way resistance loss and the local resistance loss) of the detergent flowing from the detergent-containing tank 2 into the throat section 4 of the horizontal pipe 1, and is mainly represented by the on-way resistance loss

(λ is the coefficient of on-way drag loss). In addition, the detergent-holding tank 2 is open to the atmosphere, so that the surface pressure thereof can be set to a standard atmospheric pressure, i.e., p₃＝p_a. The flow is also turbulent, so that there is:

p₁representing the static pressure of the washing water at the inlet of the level 1, which can be adjusted by the delivery pump so that it is close to atmospheric pressure, p_a-p₁Approaching 0 or constant. Rho_wρ_dThe densities of the washing water and the detergent are constant. A. the₁，A₂All the structural sizes of the horizontal pipe 1 are constant. At a constant inlet flow rate, I-IThe flow loss from the cross-section to the II-II cross-section is also constant. λ is an on-way resistance loss coefficient of the flow in the connection pipe 5, and is also a constant in a steady flow state. It can be seen that the speed v' at which the detergent is sucked into the horizontal pipe 1 from the connection pipe 5 is determined when the main flow inlet speed and the liquid level difference H are constant.

So that the operating parameter v can be adjusted₁And the structural parameter H automatically adjusts the ratio of the washing water to the detergent, so that the detergent is automatically and uniformly mixed in the water adding process, and a detergent delivery pump and a metering device are not required to be additionally configured.

In particular, for example, for 50 kg of linen per washing bin, about 800 g of detergent is mixed with about 200 kg of water. The inlet line has an internal diameter of 100 mm (DN100) and a speed of approximately 1.1 m/s, and if the throat section 4 has a through-flow diameter of 25 mm, the quantity of detergent sucked in the main flow is 0.8: 200. According to the above derivation, when the water density is about 1000 kg/cubic meter, the detergent density is about 950 kg/cubic meter, the flowing reynolds number of the inhaled detergent is greater than 5000, and the height difference H between the detergent liquid level and the main flow channel level is about 63 mm, the detergent will be inhaled into the main flow at a speed of about 1.1 m/s, so that it can be deduced that the diameter of the communicating pipe is designed to be 2 mm, that is, the ratio of the detergent flow rate to the main flow rate is ensured to be 200: 0.8.

So set up, hold the detergent in the pond 2 and inhale in the horizontal pipe 1 through the effect of rivers, and through the velocity of flow and the height of the detergent liquid level that the 1 centre-to-centre spacing detergent of the horizontal pipe 1 first end intake in the detergent holds the pond 2, can adjust the ratio of detergent and washing water. So, estimate delivery pump action time and control the mode of adding the detergent dosage among the prior art, the utility model provides a detergent adds the device and adds the detergent dosage more accurate to the detergent holds 2 interior entering into horizontal pipe 1 from the detergent, flows out from horizontal pipe 1 again, and in the whole process, detergent and washing water have intensive mixing, and detergent and washing water do not appear among the prior art and add washing unit 12 respectively in, mix inhomogeneous problem easily. Besides, the embodiment of the utility model provides a detergent adds device mainly realizes adding the detergent automatically through the structure that changes horizontal pipe 1, need not to use delivery pump etc. has reduced the cost that the detergent added the device.
